    Anterior uveitis is rare, with an annual incidence of 12/100,000 population, although it is more common in Finland (annual incidence of 23/100,000), probably because of genetic factors, such as high frequency of HLA-B27 in the population. It is often self-limiting, but can, in some cases, lead to complications such as posterior synechiae, cataract, glaucoma, and chronic uveitis. We conducted a systematic review and aimed to answer the following clinical question: What are the effects of anti-inflammatory eye drops on acute anterior uveitis? We searched: Medline, Embase, The Cochrane Library and other important databases up to November 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found six systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: corticosteroids, mydriatics, and non-steroidal anti-inflammatory drug eye drops.

    Equine recurrent uveitis (ERU), a chronic, recurrent inflammation primarily of the anterior uveal tract, is the most common cause of blindness in horses. Recently, T-lymphocytes have been found to be the most numerous cell type to infiltrate the anterior uveal of horses with ERU. In the present study, we characterized the T-lymphocyte population in the anterior uveal tract of eyes of horses with chronic ERU by evaluating the microscopic appearance (histopathologic features), the T-lymphocyte subsets, and the relative levels and amounts of T-lymphocyte cytokine mRNA in the anterior uvea. Seven inflamed eyes (from six horses with chronic ERU) and 5 normal eyes (from five horses with nonocular problems) were studied. After clinical examination, the eyes were removed, ocular fluids were aspirated, and anterior uveal tissues (iris and ciliary body) were processed for histologic and molecular (RNA isolation) analyses. Histologic examination by hematoxylin and eosin (H and E) staining and immunohistochemistry evaluating T-lymphocyte subsets (anti-CD4, CD8, CD5) were performed for each sample. RNA samples were analyzed for levels of messenger (m) RNA specific for interleukin (IL)-2, 4, and interferon-gamma (IFNgamma) by quantitative reverse transcriptase polymerase chain reaction (QRT-PCR). Eyes with ERU exhibited characteristic clinical signs, including corneal edema, aqueous flare, posterior synechia, corpora nigra degeneration, and cataract formation. Histologically, infiltration of the uveal tract with lymphocytes, plasma cells, and macrophages was most evident in the ciliary body and base of the iris. Loss of tissue structure (destruction) was most evident in the ciliary processes. Infiltrating lymphocytes were predominantly CD4+ T-cells (e.g. 48% CD4+ and 18% CD8+ in the ciliary body stroma), as determined by immunohistochemistry. Few inflammatory cells were observed in the normal eyes. The QRT-PCR results revealed increased transcription of IL-2 and IFNgamma and low

    Uveitis is an important component of many rheumatic diseases. The main causes of recurrent uveitis are seronegative spondylarthropathies and Behçet's disease. We describe a rare case of Henoch Schönlein vasculitis (HSV) along with multiple recurrences of acute anterior uveitis. In cases of skin rash and recurrent anterior uveitis, HSV should be considered in the differential diagnosis.

    To evaluate changes in inflammatory activity over time in patients with juvenile idiopathic arthritis (JIA)-associated anterior uveitis after two different types of glaucoma surgery. Retrospective analysis of 32 patients with JIA who had trabeculectomy (TE, 21 eyes) or Ahmed glaucoma valve implantation (AGV, 11 eyes). Inflammatory activity and use of anti-inflammatory medication were evaluated 1 year prior to surgery and in the first, third, and fifth years after surgery. In both groups IOP decreased significantly from pre-surgery to 2 years after surgery (TE, 31.1 ± 6.7 to 12.8 ± 6.1 mmHg, p<0.0001; AGV, 28.5 ± 8.5 to 14.9 ± 6.6 mmHg, p<0.001). In the TE group flare, anterior chamber cells, and uveitis activity decreased significantly after surgery, whereas with AGV there was no sustained reduction of flare. The degree of inflammation in JIA-associated uveitis is significantly reduced after trabeculectomy.

    Purpose To gain a better understanding of laser flare photometry values (“flare”) as a feature of chronic anterior uveitis in children; to identify relationships between flare and other patient and disease characteristics; to describe changes in flare during course of disease; and specifically to determine whether elevated flare is predictive of subsequent adverse events. Methods A retrospective review of medical records was performed for all children (aged ≤16 years at disease onset) with chronic anterior uveitis presumed to be noninfectious, who were examined by one clinician at the Jules Stein Eye Institute since laser flare photometry became available at that facility. All involved eyes were studied. Cross-sectional analysis compared initial flare to other characteristics. Relationships between potential risk factors and outcomes were studied by Kaplan-Meier analyses and Cox proportional hazards regression models. Results Included were 114 patients (198 involved eyes). Follow-up ranged from 0 to 154.8 months (median, 23.5 months for 82 patients with follow-up). Flare was related to the following factors: anterior chamber cells, keratic precipitates, papillitis, and various complications of uveitis, including band keratopathy, posterior synechiae, and cataract. Flare was not a function of disease duration. High flare was associated with an increased risk of vision loss and development of new vision-threatening complications, including glaucoma/increased intraocular pressure, during follow-up; risk was independent of anterior chamber cells. Conclusions Flare may be useful in the evaluation and management of chronic anterior uveitis in children. Flare is a marker of disease severity and is predictive of adverse events during the course of disease. PMID:18427621

  6. Childhood chronic anterior uveitis associated with vernal keratoconjunctivitis (VKC): successful treatment with topical tacrolimus. Case series

    PubMed Central

    2011-01-01

    Uveitis treatment involves topical corticosteroids along with cycloplegic-mydriatics. Particularly severe cases may require systemic corticosteroids and immunosuppressive drugs. Vernal keratoconjunctivitis (VKC) treatment consists of a brief period of topical corticosteroids and/or cyclosporine. In patients refractory to traditional treatment, the use of 0.1% topical ophtalmic FK- 506 (tacrolimus) ointment has been occasionally reported. This is the first report of the coexistence of uveitis and VKC. The documented response to topical tacrolimus eyedrop of uveitis and VKC is also of interest, in particular since to our knowledge there are no published reports on its clinical use in uveitis.

    The aim of the study was to assess the long-term efficacy and tolerability of tumour necrosis factor α (TNFα) inhibitors in the therapy of children with refractory antinuclear antibody (ANA)-associated chronic anterior uveitis. Retrospective analysis of 31 children with ANA-associated uveitis, treated with TNFα inhibitors with a follow-up period of at least 2 years. The outcome measures included: control of inflammation, corticosteroid-sparing potential and side effects. Twenty-three children (74%) were treated with adalimumab, five children (16%) with infliximab and three children (10%) with etanercept. Control of uveitis, defined as 0 anterior chamber cells while on ≤2 drops/day topical corticosteroids, was achieved in 22 of 31 patients (71%) after 1 year (95% CI 52% to 86%), and in 21 of 29 patients (72%) after 2 years of treatment (95% CI 53% to 87%). Control of uveitis was observed in 18 of 23 children (78%) treated with adalimumab, and in two of five children (40%) treated with infliximab. In all children treated with etanercept, no sufficient inflammatory control was found. Systemic corticosteroids could be discontinued in 71% (12/17 children) and topical corticosteroids in 55% (17/31) of the patients. Treatment-related side effects were found in nine children (29%, rate: 0.10/patient-year). Our data show that adalimumab and infliximab have beneficial effects in the therapy of severe ANA-associated anterior uveitis in children.

    Curcumin has been successfully applied to treat inflammatory conditions in experimental research and in clinical trials. The purpose of our study is to evaluate the efficacy of an adjunctive-to-traditional treatment with Norflo tablets (curcumin-phosphatidylcholine complex; Meriva) administered twice a day in recurrent anterior uveitis of different etiologies. The study group consisted of 106 patients who completed a 12-month follow-up therapeutic period. We divided the patients into three main groups of different uveitis origin: group 1 (autoimmune uveitis), group 2 (herpetic uveitis), and group 3 (different etiologies of uveitis). The primary end point of our work was the evaluation of relapse frequency in all treated patients, before and after Norflo treatment, followed by the number of relapses in the three etiological groups. Wilcoxon signed-rank test showed a P < 0.001 in all groups. The secondary end points were the evaluation of relapse severity and of the overall quality of life. The results showed that Norflo was well tolerated and could reduce eye discomfort symptoms and signs after a few weeks of treatment in more than 80% of patients. In conclusion, our study is the first to report the potential therapeutic role of curcumin and its efficacy in eye relapsing diseases, such as anterior uveitis, and points out other promising curcumin-related benefits in eye inflammatory and degenerative conditions, such as dry eye, maculopathy, glaucoma, and diabetic retinopathy.

    Uveitis is composed of a diverse group of disease entities, which in total has been estimated to cause approximately 10% of blindness. Uveitis is broadly classified into anterior, intermediate, posterior and panuveitis based on the anatomical involvement of the eye. Anterior uveitis is, however, the commonest form of uveitis with varying incidences reported in worldwide literature. Anterior uveitis can be very benign to present with but often can lead to severe morbidity if not treated appropriately. The present article will assist ophthalmologists in accurately diagnosing anterior uveitis, improving the quality of care rendered to patients with anterior uveitis, minimizing the adverse effects of anterior uveitis, developing a decision-making strategy for management of patients at risk of permanent visual loss from anterior uveitis, informing and educating patients and other healthcare practitioners about the visual complications, risk factors, and treatment options associated with anterior uveitis.

    Purpose To identify factors predictive of remission of inflammation in new-onset anterior uveitis cases treated at tertiary uveitis care facilities. Design Retrospective cohort study. Participants Patients seeking treatment at participating academic uveitis clinics within 90 days of initial diagnosis of anterior uveitis. Methods Retrospective cohort study based on standardized chart review. Main Outcome Measures Factors predictive of remission (no disease activity without corticosteroid or immunosuppressive treatments at all visits during a 90-day period). Results Nine hundred ninety eyes (687 patients) had a first-ever diagnosis of anterior uveitis within 90 days before initial presentation and had follow-up visits thereafter. The median follow-up time was 160 days. Systemic diagnoses with juvenile idiopathic arthritis (JIA; adjusted hazard ratio [aHR], 0.38; 95% confidence interval [CI], 0.19–0.74) and Behçet’s disease (aHR, 0.10; 95% CI, 0.01–0.85) were associated with a lower incidence of uveitis remission. Cases of bilateral uveitis (aHR, 0.68; 95% CI, 0.54–0.87) and those with a history of cataract surgery before presentation (aHR, 0.51; 95% CI, 0.29–0.87) also had a lower incidence of remission. Regarding clinical findings at the initial visit, a high degree of vitreous cells at initial presentation was associated with a lower incidence of remission (for 1+ or more vs. none: aHR, 0.72; 95% CI, 0.55–0.95). An initial visual acuity of 20/200 or worse, with respect to 20/40 or better, also was predictive of a lower incidence of remission (aHR, 0.52; 95% CI, 0.32–0.86). Conclusions Factors associated with a lower incidence of remission among new-onset anterior uveitis cases included diagnosis with JIA, Behçet’s disease, bilateral uveitis, history of cataract surgery, findings of 1+ or more vitreous cells at presentation, and an initial visual acuity of 20/200 or worse. Patients with these risk factors seem to be at higher risk of persistent

    Two female patients with histories of cancer who showed cryptogenic organizing pneumonia (COP) complications and bilateral anterior uveitis with hypopyon were examined. Both patients had suffered from COP and received intermitted systemic corticosteroid administration (SCA). The first patient, a 65-year-old woman with a history of breast cancer, showed bilateral uveitis with hypopyon. The topical corticosteroid treatment was ineffective. After SCA for the treatment of COP was started, the hypopyon gradually dissipated. Upon termination of SCA, uveitis relapses were controlled by renewed SCA. The other patient, a 69-year-old woman with a history of ovarian cancer, showed bilateral anterior uveitis with hypopyon. Her intraocular outcome did not improve by the topical corticosteroid administration, but SCA that was applied to treat COP led to remission of uveitis. Imaging examinations, biochemical analysis, symptoms or HLA-B27 antigen screenings in either patient did not explain the development of uveitis. Bilateral anterior uveitis is commonly related to autoimmune disease or systemic syndrome. We report two cases with COP that developed bilateral anterior uveitis with hypopyon resistant to topical administration but responsive to systemic administration of corticosteroid. These findings suggest that COP can be associated with the etiology of anterior uveitis.

    A 29-year-old woman who underwent laser in situ keratomileusis (LASIK) for myopic astigmatism in both eyes presented with severe pain, photophobia and decreased visual acuity in the left eye eight days after surgery. Examination revealed severe anterior uveitis with fibrinous exudates in the anterior chamber, flap edema and epithelial bullae. Laboratory investigations for uveitis were negative and the patient required systemic and intensive topical steroids with cycloplegics to control the inflammation. This case demonstrates that severe anterior uveitis may develop after LASIK and needs prompt and vigorous management for resolution. PMID:19574707

    The purpose of this study is to determine whether pupillary dilation has any effect on anterior chamber flare measurements using a Kowa laser flare meter (FM-500) in patients with chronic anterior uveitis (CAU). Twenty-five eyes of 25 consecutive patients with CAU were assessed for anterior chamber inflammation by an experienced operator using the Kowa laser flare meter. Ten measurements were taken in total, with the highest and the lowest measurements deducted. The mean value and standard deviation was then recorded. One drop of tropicamide 1% and phenylephrine 2.5% was then applied and after 30 min the measurements were repeated and the results recorded. Sixteen women (64%) and nine men (36%) were recruited. The majority of patients were white Caucasian (68%). Fifteen left and ten right eyes were studied and the median (interquartile range: IQR) visual acuity was 6/9 (6/6-6/18). Iris colour was classified as brown, blue, grey/hazel and hazel. Thirteen eyes (52%) had brown irises, eight (32%) had blue, two had grey and the remainder were grey/hazel and hazel. The mean (SD) age was 50.8 (12.59) years. The median (IQR) flare reading before dilation was 17.93 (8.33-29.93) and after dilation was 15.97 (10.17-29.4). The mean change was -0.74 which was not a statistically significantly different to 0 (P=0.25) and the 95% limits of agreements ranged from -6.91 to 5.43. This study showed little evidence of any systematic difference between dilated and undilated flare measurements. The measurement of flare was not affected by the dilation of the pupil and measurements could be taken before or after papillary dilation for the purpose of patient follow-up data and clinical studies.

    To investigate possible relationships between laser flare photometry values, complications of uveitis, and outcomes in children with chronic uveitis. Retrospective chart review. We evaluated patients with active, noninfectious anterior, intermediate, or panuveitis who were 16 years of age or younger and who had laser flare photometry at one of two academic institutions. Complications enumerated at baseline and during follow-up were compared with laser flare photometry values and to anterior chamber cell counts. At least one laser flare photometry value ("flare"), defined as baseline measurement, was available for 59 patients (41 girls, 18 boys; mean age, 10.3 +/- 3.5 years); 38 of these patients had at least one additional measurement during follow-up (median 11 months). Complications of uveitis were present in 35 patients (59%) at baseline. There was a positive association between increased laser flare photometry values and complications at baseline (any complication [P =.007], posterior synechiae [P =.003]). The development of complications during follow-up was associated with the presence of complications at baseline (P =.018). A subgroup of patients with low flare at baseline had no complications during follow-up regardless of treatment given. There is a positive relationship between laser flare photometry values and the prevalence of complications of uveitis in children. Laser flare photometry provides a novel way to monitor children with uveitis. Future study will be needed to determine whether values have prognostic importance and whether a treatment strategy that minimizes flare results in fewer uveitic complications.

    To evaluate the effectiveness of treatment with cyclosporine A 0.05% eye drops in reducing frequency and severity of recurrences in patients with recurrent anterior uveitis. A retrospective case-crossover study was conducted by reviewing medical charts of patients treated for recurrent anterior uveitis between 2002 and 2011 at the Kellogg Eye Center by one cornea specialist. We identified patients who had been treated with topical cyclosporine A 0.05% and recorded data regarding demographics, episodes of anterior uveitis, severity of episodes and treatment modalities before and after initiation of cyclosporine A 0.05%. Eight patients were identified as having been treated with topical cyclosporine 0.05% in addition to standard treatment with an average follow-up of 54.9±33.9 months (range: 28-143 months). The patients had statistically significant fewer episodes of anterior uveitis, shorter duration of episodes and fewer total days of inflammation per year while on topical cyclosporine 0.05%. This study showed improvement of recurrent anterior uveitis in patients while on conventional treatment with cyclosporine A 0.05% compared with conventional treatment alone.

    Three mongrel dogs, aged 10 months (case 1), 14 months (case 2) and 7.5 years (case 3), were presented because of ophthalmologic disorders of 4 months, 6 months and 7 years duration, respectively. All three dogs were offspring of stray dogs from Hungary and Serbia and had positive serum antibody titres against Encephalitozoon (E.) cuniculi. The two young dogs showed unilateral, the older dog bilateral chronic anterior uveitis with posterior synechia and focal anterior cortical cataract. The fundi that could be evaluated developed focal tapetal hyporeflective lesions in the course of the disease. Dogs 1 and 2 underwent removal of the lens via phacoemulsification. PCR of the lens material was positive for E. cuniculi strains IV and II, respectively. In dog 2 findings suggestive of microsporidia were detected underneath the anterior lens capsule by immunohistochemical staining. In all cases medical treatment consisted of systemic fenbendazole, prednisolone, and topical anti-inflammatory drugs, and additional brinzolamid/timolol for dog 3. For the time being all cases (follow up 23 months, 6 months and 3 months, respectively) are still on topical anti-inflammatory therapy. It is concluded that E. cuniculi infections can cause cataract and chorioretinal lesions in dogs.

    2016-01-01

    Fingolimod is an oral sphingosine-1-phosphate (S1P) receptor modulator and the first oral therapy for relapsing-remitting multiple sclerosis. Its use has been complicated by a low rate of cystoid macular edema usually in the first 3 months after commencement of the medication. We report the case of a 34-year-old male with relapsing-remitting multiple sclerosis, who developed acute anterior uveitis on day 5 of fingolimod treatment. He responded to appropriate treatment and cessation of drug, but developed low-grade chronic anterior uveitis without cystoid macular edema. We discuss possible mechanisms of uveitis onset in this group of patients. Urgent ophthalmological review is recommended for patients receiving fingolimod therapy who develop a red, painful eye, which may occur within 5 days of fingolimod treatment initiation.

    2005-01-01

    Background Zoledronic acid is very widely used in patients with metastatic bone disease and osteoporosis. Only one case of bilateral uveitis was recently reported related to its use. Case presentation We report the first case of severe unilateral anterior uveitis in a patient with breast cancer and an intraocular lens. Following zoledronic acid infusion, the patient developed severe and dramatic right eye pain with decreased visual acuity within 24 hours and was found to have a fibrinous anterior uveitis of moderate severity The patient was treated with topical prednisone and atropine eyedrops and recovered slowly over several months. Conclusion Internists, oncologists, endocrinologists, and ophtalmologists should be aware of uveitis as a possible complication of zoledronic acid therapy. Patients should be instructed to report immediately to their physicians and treatment with topical prednisone and atropine eyedrops should be instituted immediately at the onset of symptoms. This report documents anterior uveitis as a complication of zoledronic acid therapy. This reaction could be an idiosyncratic one but further research may shed more light on the etiology.

  2. Frequency of dendritiform inflammatory cells in the cornea in herpetic anterior uveitis without clinical keratitis and Fuchs uveitis

    PubMed Central

    2014-01-01

    Background Herpetic anterior uveitis is a frequent cause of infectious uveitis. A definite diagnosis is obtained by anterior chamber puncture and polymerase chain reaction, an invasive procedure. We hypothesized that patients with herpetic anterior uveitis have a certain pattern of inflammatory cells in their cornea that distinguishes herpetic anterior uveitis from other uveitis types. This study is a prospective, controlled, observational study. Ten patients are with active herpetic anterior uveitis and 14 patients are with Fuchs uveitis syndrome. Patients were imaged with the Heidelberg Retina Tomograph with the Rostock Cornea Module attachment. Three images of the subepithelial area of the cornea were evaluated for dendritiform inflammatory cells. Means were calculated and used for analysis. The contralateral unaffected eyes and numbers published in the literature served as controls. Results The number of dendritiform inflammatory cells in herpetic anterior uveitis was compared to that in the Fuchs uveitis syndrome. Of the eyes of patients with herpetic anterior uveitis, 80% had an average of 98.0±10.8 cells/mm2 (mean±standard error of the mean (SEM), n=10) in their affected eyes and 60.4±26.4 cells/mm2, (n=6) in 30% of their fellow eyes. Patients with Fuchs uveitis syndrome had moderately elevated dendritiform inflammatory cells (47.0±9.7 cells/mm2, n=14) in 96.4% of their affected eyes and normal numbers (23.0±7.3 cells/mm2, n=13) in 46.4% of their fellow eyes. The difference between the four groups was significant (p=0.0004). Conclusions Patients with herpetic anterior uveitis had significantly higher levels of dendritiform inflammatory cells in their subepithelial cornea than patients with Fuchs uveitis syndrome, which can be detected by in vivo confocal microscopy. The clinically unaffected eyes of herpetic anterior uveitis patients showed a co-response regarding dendritiform inflammatory cell elevation. We conclude that high numbers of dendritiform

    To determine the incidence of elevated intraocular pressure (IOP) and secondary glaucoma in herpetic anterior uveitis (AU), owing to either herpes simplex or varicella zoster virus, by using the Standardization of Uveitis Nomenclature (SUN) criteria, and to identify risk factors for the development of glaucoma. Retrospective observational cohort study. Patients with herpetic AU presenting themselves between 2001 and 2013 at the ophthalmology department of the University Medical Center Groningen were included. Main outcome measures were the incidence of elevated IOP and glaucoma and risk factors for the development of glaucoma. Seventy-three herpetic AU patients were included. Ocular complications most commonly seen during follow-up for uveitis were elevated IOP (75%), keratitis (59%), dry eyes (34%), posterior synechiae (34%), cataract (32%), and glaucoma (15%). Glaucoma patients, in comparison to non-glaucoma patients, had a higher number of IOP peaks during their follow-up for uveitis (P < .001). The majority of patients with elevated IOP (91%) had this already at the start of the uveitis. Nineteen percent of the patients needed glaucoma surgery. Using the SUN criteria, our study confirmed that elevated IOP and secondary glaucoma are major complications in herpetic AU. If an elevated IOP occurred, it was usually already present at the start of a uveitis episode. A risk factor for the development of glaucoma was the number of endured IOP peaks. Future studies are needed to evaluate whether early and prolonged use of antiviral and IOP-lowering medication may prevent glaucoma. Copyright © 2017 Elsevier Inc. All rights reserved.

    Recent studies have sought to quantify aqueous flare by laser flare measurement. An increase in aqueous flare caused by a rise of protein concentration was frequently found both in anterior and posterior segment disease. This has been interpreted as a break-down of the blood--aqueous barrier (BAB). By measuring the diffusion coefficient of the BAB compared to the aqueous flare value in patients with anterior and posterior uveitis, the extent to which the increase in flare value was related to a possible break down of the BAB was examined. Thirty-nine normal eyes (23-78 years; 41.6 +/- 18.6), 18 eyes with anterior uveitis (iritis, iridocyclitis; 18-57 years; 35.2 +/- 12.4) and 29 eyes with posterior uveitis (chorioretinitis or retinochorioditis; 18-51 years; 31.7 +/- 10.5). The diffusion coefficient P(a) of the BAB was measured fluorophotometrically, while the flare value was quantified by laser flare measurement. Flare values (1/ms) were found to be significantly increased (p < 0.001) compared to normal eyes (4.6 +/- 1.7) both in anterior uveitis (20.9 +/- 8.5) and in posterior uveitis (17.4 +/- 8.3) but did not significantly differ between them (p = 0.43). The diffusion coefficient P(a) (10(-3)/min) of the BAB was not significantly different (p > 0.05) between normal eyes (0.5 +/- 0.2) and eyes with posterior uveitis (0.9 +/- 0.7), whereas it was significantly increased (p < 0.001) in anterior uveitis (6.5 +/- 5.4) compared to the other groups. (1) In posterior uveitis, an increased flare value is not necessarily correlated with a breakdown of the BAB; proteins may enter the aqueous from posterior. (2) Assessing the function of the BAB in posterior segment disease using laser measurement should be carried out with caution; if possible, permeability measurements of the BAB should be undertaken separately.

    Systemic sclerosis (SSc) sine scleroderma (ssSSc) is characterized by the absence of skin involvement, despite other manifestations of systemic sclerosis are present. It is not known whether sSSc represents a forme fruste of limited cutaneous SSc or a distinct entity, but the 2013 American College of Rheumatology/European League Against Rheumatism criteria for the classification of SSc have considered SSc without skin involvement to be a distinct subset. The authors present the case of a 70-year old female that was referred for a consultation for Raynaud's phenomenon and a chronic anterior uveitis (CAU). She had a history of dysphagia, diffuse pulmonary emphysema and a biopsy-documented fibrosis of the upper lobes, and an idiopathic non-ischemic dilated cardiomyopathy with severe left ventricle systolic dysfunction and left bundle branch block. Anti-nuclear and anti-centromere antibodies were positive, while manometry revealed distal esophageal hypomotility. After establishing the diagnosis of ssSSc and starting immunosuppression, the ocular disease improved, while the lung and heart diseases remained stable. This case underlines that it is very important to suspect SSc when CAU is present and/or skin thickening is absent. To our knowledge, this is the first report of CAU in a patient with ssSSc.

    2013-01-01

    Background The objective of the study is to report a case of unilateral anterior uveitis after laser hair removal of the eyebrows with an alexandrite laser. Findings A 36-year-old female presented with painful red eye and photophobia in her left eye 2 days after receiving alexandrite (755 nm) laser epilation of both eyebrows. Visual acuity was 20/20 in both eyes. Right eye examination was normal. Left eye examination showed conjunctival injection, 2+ cells in the anterior chamber, and local posterior synechiae. Intraocular pressure and fundus examination were normal in both eyes. Topical steroids and cycloplegic drops were prescribed. Three days after the initiation of topical treatment, there was a reduction in anterior chamber cells to 1+, but posterior synechiae was enhanced. One week after, there were 0.5+ cells in the anterior chamber and no further enlargement of posterior synechiae. At the 2-month follow-up, uncorrected visual acuity remained 20/20 in both eyes. Slit-lamp biomicroscopy of the right eye was normal. Intraocular pressure and fundus examination were still normal in both eyes. Although anterior chamber of the left eye was clear, posterior synechiae persisted. We are still following the patient. Conclusion Laser hair removal of the eyebrows can lead to ocular damage and should be avoided. PMID:23587197

    Uveitis is a potentially sight-threatening disease characterized by repeated cycles of remission and recurrent inflammation. The JAK/STAT pathway regulates the differentiation of pathogenic Th1 and Th17 cells that mediate uveitis. A SOCS1 mimetic peptide (SOCS1-KIR) that inhibits JAK2/STAT1 pathways has recently been shown to suppress experimental autoimmune uveitis (EAU). However, it is not clear whether SOCS1-KIR ameliorated uveitis by targeting JAK/STAT pathways of pathogenic lymphocytes or via inhibition of macrophages and antigen-presenting cells that also enter the retina during EAU. To further investigate mechanisms that mediate SOCS1-KIR effects and evaluate the efficacy of SOCS1-KIR as an investigational drug for chronic uveitis, we induced EAU in rats by adoptive transfer of uveitogenic T-cells and monitored disease progression and severity by slit-lamp microscopy, histology, and optical coherence tomography. Topical administration of SOCS1-KIR ameliorated acute and chronic posterior uveitis by inhibiting Th17 cells and the recruitment of inflammatory cells into retina while promoting expansion of IL-10-producing Tregs. We further show that SOCS1-KIR conferred protection of resident retinal cells that play critical role in vision from cytotoxic effects of inflammatory cytokines by downregulating proapoptotic genes. Thus, SOCS1-KIR suppresses uveitis and confers neuroprotective effects and might be exploited as a noninvasive treatment for chronic uveitis. PMID:27703302

    Rubella virus is involved in the pathogenesis of Fuchs heterochromic uveitis and almost all cases in Europe show an active antibody production in the aqueous humor against rubella virus. Herein we report a case of a fully vaccinated patient with common variable immunodeficiency who developed unilateral Fuchs heterochromic uveitis secondary to rubella virus which was proven by intraocular fluid examination. Awareness of rubella associated anterior uveitis should remain also in vaccinated patients, especially those without a fully competent immune system.

    This article presents a comprehensive approach of the diagnosis of anterior uveitis and appropriate investigational tests based on clinical signs. Uveitis has classically been presented by uveitis specialists as an obscure and complicated field in ophthalmology that was supposed to be restricted to the happy few who had the knowledge, which in some countries was even prevented from being diffused. The effect was that ophthalmologists turned away from uveitis or were not correctly armed when they chose to take care of uveitis patients. The consequences of this situation often fell upon the patients. Since more than 15 years our group has been represented by the Society for Ophthalmo-Immunoinfectiology in Europe (SOIE), which has been working to alter this image of uveitis and ensure that the knowledge of the basics of uveitis reaches the practicing ophthalmologist. Our firm believe is that up to 70% of uveitis cases, especially anterior uveitis, can be taken care of by the practicing ophthalmologist following a structured approach in the appraisal of the uveitis case. Judging from the attendance obtained, the response to our approach in every country (where we organise courses) has been inversely proportional to the previous disinterest since we started publicizing it.

    Endogenous uveitis in 117 children aged 15 years or under was investigated at The Hospital for Sick Children, Toronto, in a 12-year period from 1953 to 1964. This group included 55 children with anterior uveitis, 59 with posterior uveitis, and three with diffuse uveitis. An etiologic diagnosis could be made or the uveitis recognized as part of a definite clinical syndrome in approximately 47% of the 117 children. The commonest cause of posterior uveitis was toxoplasmosis and the commonest associated finding in anterior uveitis was juvenile rheumatoid arthritis. Chronic cyclitis of unknown etiology was a relatively common disease. ImagesFig. 1Fig. 2Fig. 3Fig. 4Fig. 5Fig. 6Fig. 7 PMID:6066889

    Anterior uveitis is far more common than intermediate, posterior or panuveitis. About 50% of patients with acute anterior uveitis are HLA B27+. Those who are HLA B27+ are highly likely to have associated back, joint, or tendon disease. The majority of patients with acute anterior uveitis and inflammatory low back pain are suffering from axial spondyloarthritis and radiographic evidence for abnormal sacroiliac joints is not required to make this diagnosis.

This study reports the case of a female patient with acute unilateral anterior uveitis caused by alexandrite laser-assisted hair removal of the eyebrows. We report a 38-year-old female who presented with unilateral eye pain, redness, and photophobia after receiving alexandrite (755 nm) laser epilation of both eyebrows. Best corrected visual acuity was 20/20 in both eyes. Right eye examination was normal. Left eye examination showed conjunctival injection and 2+/3+ cells in the anterior chamber. Intraocular pressure and fundus examination were normal. Topical steroids and cycloplegic drops were prescribed for 3 weeks. At the end of the 3-week follow-up, best corrected visual acuity was 20/20, and intraocular pressure and fundus examination were normal in both eyes. The left eye was white, and the anterior chamber was clear. The patient continues to be monitored. In conclusion, without adequate protective eyewear, laser hair removal of the eyebrows with alexandrite laser can lead to ocular damage.

    We investigated inflammatory cell infiltrates in iris biopsies in uveitis associated with juvenile idiopathic arthritis (JIA) in comparison with other pediatric uveitis entities and noninflammatory pediatric controls. Iridectomy specimens were obtained during elective trabeculectomy from 31 eyes of 25 patients: 12 eyes with JIA-associated uveitis, 13 eyes with other uveitis entities, and 6 eyes with open angle nonuveitic juvenile glaucoma. Histopathologic and immunohistochemical analyses were performed. A semiquantitative scoring system was used with a scale ranging from 0 to 4 depending on the number of stained cells. An inflammatory infiltrate was present in 8/12 (67%) specimens with JIA-associated uveitis. The cellular infiltrate in JIA specimens was characterized by the presence of CD138+ plasma cells and CD68+ macrophages, while the presence of CD20+, CD4+, and CD8+ cells was variable. Presence of plasma cells in the inflammatory infiltrates in anterior uveitis correlated with antinuclear autoantibody (ANA) positivity regardless of the diagnosis of JIA. CD4+ and CD8+ T cells were not always detectable in the iris biopsies of all childhood uveitis patients, although a slight predominance of CD4+ cells was noted. Children with ANA-positive anterior uveitis often show an infiltrate of plasma cells, regardless of the diagnosis of JIA. The iris of JIA-associated uveitis patients is additionally characterized by the presence of various numbers of macrophages.

    Background Uveitis is a term used to describe a heterogeneous group of intraocular inflammatory diseases of the anterior, intermediate, and posterior uveal tract (iris, ciliary body, choroid). Uveitis is the fifth most common cause of vision loss in high-income countries, accounting for 5% to 20% of legal blindness, with the highest incidence of disease in the working-age population. Corticosteroids are the mainstay of acute treatment for all anatomical subtypes of non-infectious uveitis and can be administered orally, topically with drops or ointments, by periocular (around the eye) or intravitreal (inside the eye) injection, or by surgical implantation. Objectives To determine the efficacy and safety of steroid implants in people with chronic non-infectious posterior uveitis, intermediate uveitis, and panuveitis.

    To develop recommendations on the use of immunodepressors in patients with non-infectious, non-neoplastic anterior uveitis (AU) based on best evidence and experience. A multidisciplinary panel of five experts was established, who, in the first nominal group meeting defined the scope, users, and chapters of the document. A systematic literature review was performed to assess the efficacy and safety of immunosuppressors in patients with non-infectious, non-neoplastic AU. All the above was discussed in a second nominal group meeting and 33 recommendations were generated. Through the Delphi methodology, the degree of agreement with the recommendations was tested also by 25 more experts. Recommendations were voted on from one (total disagreement) to 10 (total agreement). We defined agreement if at least 70% voted ≥7. The level of evidence and degree of recommendation was assessed using the Oxford Centre for Evidence-based Medicine's Levels of Evidence. The 33 recommendations were accepted. They include specific recommendations on patients with non-infectious, non-neoplastic AU, as well as different treatment lines. In patients with non-infectious, non-neoplastic AU, these recommendations on the use of immunosuppressors might be a guide in order to help in the treatment decision making, due to the lack of robust evidence or other globally accepted algorithms.

    Multidisciplinary management in the diagnosis and management of patients with ocular inflammatory disease is often critical. The workup of uveitis or scleritis may reveal an underlying systemic disease. Recognition of inflammation by the primary care physician can facilitate prompt referral to a uveitis specialist and improve patient outcomes. The primary care physician can assist the ophthalmologist in monitoring for potential side effects of corticosteroids and immunosuppressive drugs, including the newer biologic agents. The ophthalmologist in turn can assist the primary care physician in recognizing that active uveitis may suggest incomplete control of preexisting conditions.

    Purpose To measure thrombopoietin (TPO) levels in the serum and aqueous humors of patients with noninfectious acute anterior uveitis. Methods A prospective, comparative, controlled study. Serum and aqueous humors were obtained from the eyes of 16 patients with noninfectious acute anterior uveitis. TPO levels were measured using an enzyme-linked immunosorbent assay (ELISA). The results obtained were compared with those of a control group. Results Serum concentrations of TPO were not significantly different between control individuals and patients with active anterior uveitis. Aqueous humor TPO levels were 54.46±16.24 pg/mL in the eyes of patients with uveitis, and 34.32±11.63 pg/mL in the eyes of controls. The difference between the two groups was significant (Mann–Whitney U-test for independent data, P=0.0008), with uveitis patients exhibiting significantly higher levels of TPO. Conclusion The high levels of TPO in the aqueous humors of uveitis patients points toward a cytoprotective role of this factor in inflammatory repair processes and the recovery of tissue homeostasis.

    Purpose Since few reports had been published on the prevalence of toxocariasis in ankylosing spondylitis (AS) patients with acute non-granulomatous anterior uveitis (ANGAU), the aim of this work was to determine the presence of antibodies against Toxocara canis in AS patients with ANGAU. Methods Thirty-six patients (14 female and 22 male) with AS were enrolled in the study. The history of ANGAU was accepted only if diagnosed by an ophthalmologist. The detection of IgG antibodies to T. canis was determined by enzyme-linked immunosorbent assay. In addition, antibodies to Ascaris lumbricoides were also tested to verify non-specific reactions. Results The prevalence of ANGAU in the AS patients was 58% (21 / 36), and 38% (8 / 21) of the patients with ANGAU were positive for antibodies to Toxocara, while 7% (1 / 15) of AS patients without ANGAU were positive for T. canis (p = 0.038, two tails; mid-p exact). No antibodies were detected to A. lumbricoides antigens in the serum samples of patients with AS. Conclusions These data suggest that the seroprevalence of antibodies to T. canis is high in Mexican patients with AS-associated uveitis, suggesting a chronic asymptomatic toxocariosis, which could be associated with the pathogenesis of ANGAU; however, further larger-scale studies are needed to confirm this observation.

    Uveitis, or ocular inflammation, is a cause of severe visual impairment. Rodent models of uveitis are powerful tools used to investigate the pathological mechanisms of ocular inflammation and to study the efficacy of new therapies prior to human testing. In this paper, we report the utility of spectral-domain optical coherence tomography (SD-OCT) angiography in characterizing the inflammatory changes induced in the anterior segment of a rat model of uveitis. Acute anterior uveitis (AAU) was induced in two rats by intravitreal injection of a killed mycobacterial extract. One of them received a concurrent periocular injection of steroids to model a treatment effect. OCT imaging was performed prior to inflammation induction on day 0 (baseline), and 2 days post-injection (peak inflammation). Baseline and inflamed images were compared. OCT angiography identified swelling of the cornea, inflammatory cells in the anterior and posterior chambers, a fibrinous papillary membrane, and dilation of iris vessels in the inflamed eyes when compared to baseline images. Steroid treatment was shown to prevent the changes associated with inflammation. This is a novel application of anterior OCT imaging in animal models of uveitis, and provides a high resolution, in vivo assay for detecting and quantifying ocular inflammation and the response to new therapies.

    Anterior uveitis (AU), inflammation of the iris, choroid, or ciliary body, can cause significant eye morbidity, including visual loss. In the pediatric age group, the most common underlying diagnosis for AU is juvenile idiopathic associated uveitis and idiopathic AU, which are the focus of this paper. AU is often resistant to medications such as topical corticosteroids and methotrexate. In the past 15 years, biologic agents (biologics) have transformed treatment. In this review, we discuss those in widespread use and those with more theoretical applications for anterior uveitis. Tumor Necrosis Factor alpha inhibitors (anti-TNFα) have been available the longest and are used widely to treat pediatric uveitis. The effects of anti-TNFα in children are described mostly in small retrospective case series. Together, the literature suggests that the majority of children treated with anti-TNFα achieve decreased uveitis activity and reduce corticosteroid burden. However, many will have disease flares even on treatment. Only a few small studies directly compare outcomes between alternate anti-TNFα (infliximab and adalimumab). The use of different uveitis grading systems, inclusion criteria, and outcome measures, makes cross-study comparisons difficult. Whether the achievement and maintenance of inactive disease occurs more frequently with certain anti-TNFα remains controversial. Newer biologics that modulate the immune system differently (e.g., interfere with TH17 activation through IL-17a and IL-6 blockade, limit T lymphocyte costimulation, and deplete B lymphocytes), have shown promise for uveitis. Studies of these agents are small and include mostly adults. Additional biologics are also being explored to treat uveitis. With their advent, we are hopeful that outcomes will ultimately be improved for children with AU. With many biologics available, much work remains to identify the optimal inflammatory pathway to target in AU. PMID:25893479

    Cyclosporine (CsA) is a widely used drug in the treatment of posterior uveitis. Whereas treatment with CsA has considerably improved the visual prognosis of uveitis patients, the therapeutic benefits of CsA are partially outweighed by its adverse effects, most notably nephrotoxicity and hypertension. Recently, monitoring the CsA 2-h postdose level (C(2)) has been recommended as the most sensitive assay and predictor of clinical outcome in transplantation. This prospective clinical trial included 15 patients with posterior uveitis who received oral CsA (5 mg/kg BW b.i.d.). The relationship of C(2) to C0 blood levels was analyzed and correlated with clinical safety and efficacy. A high intrapatient and interpatient variability was observed regarding the C0 values depending on several factors including comedication and intestinal resorption. C(2) values corresponded to control measurements of intraocular inflammation. C(2) monitoring offers a simple and accurate alternative for clinical monitoring of CsA. It allows the dose of CsA to be individualized effectively for each patient.

    Uveitis specialists and rheumatologists treat patients with anterior scleritis, but data from controlled trials to guide management are scarce, making differences in treatment paradigms possible. 1044 uveitis specialists and rheumatologists were surveyed regarding therapy for a patient with anterior scleritis. Respondents were asked to select first- and second-choice therapies and then reselect therapies assuming that the costs of all options were equal and that insurance approval was ensured. Fisher's exact tests were employed to compare selections. Ninety-two respondents (8.6%) completed the survey. Methotrexate was the most-selected first-choice treatment before equalization of cost/insurance factors among uveitis specialists (44.4%) and rheumatologists (78.6%) (p < 0.009). Uveitis specialists selected mycophenolate at a higher rate (27.8%) than did rheumatologists (5.3%) (p < 0.015). Cost and insurance considerations were not significant. Uveitis specialists and rheumatologists have different preferences in the treatment of anterior scleritis. The difference is impacted more by specialty practice than by cost/insurance.

    HLA-B27 is a transplantation antigen found in a high proportion of patients with ankylosing spondylitis. Recently, an association has been shown to exist between HLA-B27 and acute uveitis, even in the absence of ankylosing spondylitis. We have examined the HLA antigen profile of 45 patients with acute nongranulomatous anterior uveitis and have confirmed this relation. In addition, using 90mtechnetium stannous pyrophosphate we have been able to demonstrate abnormal bone scan in 19 of 30 patients studied. Such abnormalities are limited to the sacroiliac joints but are otherwise the same as those seen in overt ankylosing spondylitis. Seven of the 19 patients did not have HLA-B27. These factors suggest that acute anterior uveitis may often represent a manifestation of a spondylitic diathesis even in the complete absence of any suggestive symptomatic or radiologic change and, in some cases, even though the antigenic marker HLA-B27 may be absent.

    Background A few reports have described ocular complications of influenza A infection, such as impaired ocular movement, parasympathetic ocular nerve, keratitis, macular lesion, and frosted branch angiitis. We encountered a rare case of acute anterior uveitis and optic neuritis associated with influenza A infection. Case presentation A 70-year-old man presented with symptoms of upper respiratory tract infection. A rapid diagnostic test showed a positive result for influenza A. At the same time, he developed ocular symptoms including blurred vision with optic disk edema and hemorrhage in the left eye, and bilateral red eyes. Multiplex polymerase chain reaction performed on aqueous humor sample detected no viral infection. Visual field testing with a Goldmann perimeter showed central and paracentral scotomas in the left eye. In addition to antiviral agent (oseltamivir phosphate 75 mg), the patient was prescribed topical prednisolone acetate ophthalmic suspension eye drops every 5 hours and high-dose intravenous methylprednisolone 1,000 mg daily for 3 days. Two months later, his best-corrected visual acuity improved to 20/50 with regression of visual field defects in his left eye. Conclusion We report a case of bilateral acute anterior uveitis and unilateral optic neuritis concomitant with influenza A infection. Topical and systemic corticosteroids were effective to resolve acute anterior uveitis and neuritis. Analysis of aqueous humor sample suggested that acute anterior uveitis and optic neuritis in this case were not caused by influenza A virus infection per se but by autoimmune mechanism.

    The sudden onset of unilateral blepharospasm and hyphema, without evidence of corneal damage, initiated a thorough diagnostic work-up of an 11-wk-old purpose-bred intact male domestic shorthair kitten. Secondary acute anterior uveitis and hyphema were most likely due to trauma within the primary enclosure.

    In a randomised double-masked study of 27 patients with a severe chronic idiopathic uveitis we evaluated the efficacy, safety, and tolerability of cyclosporin. All received prednisone in a low dose (0.3 mg/kg/day). In 14 patients this was combined with cyclosporin in a single daily dose of 10 mg/kg/day, while 13 patients received a placebo. The dosages were tapered off in accordance with a protocol, and we compared the number of months of successful therapy before the uveitis relapsed. The efficacy results, as expressed in a Kaplan-Meier curve, were in favour of cyclosporin. Owing to the small sample size, however, this difference did not reach statistical significance. The immunosuppressive effect of cyclosporin was not permanent, and in all but one patient the intraocular inflammation relapsed on reduction of dosage. Rather small cumulative doses of cyclosporin proved to be nephrotoxic, but subjective tolerability for cyclosporin was good. PMID:2198928

    This report aims to describe the facilitating role of in vivo confocal microscopy in differentiating inflammatory cells from a metastatic process in a patient with uveal melanoma and multiple systemic metastases who developed anterior uveitis while under ipilimumab treatment. A 43-year-old woman developed systemic metastases 11 months after treatment of amelanotic choroidal melanoma in her right eye with 30 Gy fractionated stereotactic radiotherapy. She first received temozolomide and then 4 cycles of ipilimumab 3 mg/kg/day. After the third cycle, severe anterior uveitis with coarse pigment clumps on the lens was seen in the left eye. Her left visual acuity declined from 20/20 to 20/80. Confocal microscopy revealed globular keratic precipitates with hyperreflective inclusions and endothelial blebs all suggestive of granulomatous uveitis. The uveitic reaction subsided after a 3-week course of topical corticosteroids, and her visual acuity was 20/20 again. Although uveal melanoma metastatic to the intraocular structures of the fellow eye is exceedingly rare and metastasis masquerading uveitis without any identifiable uveal lesion is even more unusual, it was still mandatory to rule out this distant possibility in our particular patient who already had widespread systemic metastases. Confocal microscopy was a useful complementary tool by identifying the inflammatory features of the keratic precipitates. PMID:27790127

    Lymphoplasmacytic endotheliitis and anterior uveitis was diagnosed in four lambs infected experimentally with field isolates of Rift Valley fever virus (RVFV). Formalin-fixed and paraffin wax-embedded tissue from these animals was investigated by histopathology and quantitative real time reverse transcriptase polymerase chain reaction. To our knowledge, this is the first pathological description of this ocular manifestation of RVFV infection in ruminants, although these lesions have been described in man.

    To describe aqueocentesis cytopathology results from dogs and cats presenting for uveitis investigation and to determine whether this is a useful and safe procedure. Dogs and cats presenting for investigation of anterior uveitis (April 2008-December 2013). Aqueous was collected via limbal entry under sedation/general anesthesia, for cytopathology and occasionally bacterial culture or polymerase chain reaction (PCR) testing. Further workup included blood testing (hematology, biochemistry, and serology), diagnostic imaging, nonocular cytopathology, and available histopathology. Fifty-six dogs and 39 cats were included in the study. An aqueous cytopathologic diagnosis of lymphoma (or discrete cell neoplasia) was made in six dogs and seven cats, and a diagnosis of large cell carcinoma made in one dog. This diagnosis of lymphoma was confirmed by ocular histopathology in two dogs and one cat; nonocular cytopathology corroborated lymphoma in another three dogs and five cats. Lymphoma was not evident on aqueous cytopathology but confirmed on nonocular histopathology in two dogs and by cytopathology in one cat. Additionally, aqueous cytopathology in three cats suggested, but was not considered diagnostic of, lymphoma; one of these cats had a confirmatory diagnosis of lymphoma on subsequent clinical investigation. Aqueous humor cytopathology alone was not diagnostic in non-neoplastic anterior uveitis cases, but supplemented the clinical picture with other systemic diagnostic tests. No clinically important complications were reported in association with aqueocentesis. Aqueocentesis is performed readily with minimal risk. The results were primarily useful in aiding a diagnosis of lymphoma in both dogs and cats. © 2014 American College of Veterinary Ophthalmologists.

  12. Recurrent symptomatic intraocular pressure spikes during hemodialysis in a patient with unilateral anterior uveitis

    PubMed Central

    2013-01-01

    Background The relationship between intraocular pressure (IOP) changes and hemodialysis has been evaluated for several decades. However, no report on an IOP rise in uveitis patients during hemodialysis has been previously documented. This report describes the case of an uveitis patient with repetitive IOP spikes associated with severe ocular pain during hemodialysis sessions, which resolved after glaucoma filtering surgery. Case presentation A 47-year-old male with diabetes and hypertension had complained of recurrent ocular pain in the left eye during hemodialysis sessions. A slit-lamp examination showed diffuse corneal epithelial edema with several white keratic precipitates and inflammatory cells (Grade 3+) in the anterior chamber of the left eye. No visible neovascularization or synechiae were visible on the iris or angle. Topical glaucoma eye-drops and intravenous mannitol before hemodialysis did not prevent subsequent painful IOP spikes in the left eye. At the end of hemodialysis, IOP averaged ~40 mmHg. After trabeculectomy with mitomycin C in the left eye, his IOP stabilized in the low-teens (range, 10–14 mmHg) and no painful IOP spikes occurred during hemodialysis over the first postoperative year. Conclusion We present a case of recurrent painful IOP spikes during hemodialysis in a patient with unilateral anterior uveitis unresponsive to conventional medical treatment prior to hemodialysis. To our knowledge, this is the first case report of repetitive symptomatic IOP rise during hemodialysis in an uveitic glaucoma patient. This case highlights the importance of the awareness of the possibility that IOP may rise intolerably during hemodialysis in uveitis patients with a compromised outflow facility. PMID:23384186

    A 38-year-old woman with diabetes mellitus complained of acute visual loss in the left eye (20/200) and swollen left upper eyelid. Slit lamp examination of the left eye revealed ciliary injection, posterior synechia iritis, numerous inflammatory cells, and fibrin exudates in the anterior chamber. T1-weighted enhanced magnetic resonance imaging demonstrated left lacrimal gland enhancement with inflammatory spread to the left anterior ocular segment. Blood examination showed increased blood sugar but the other components were within normal limits. The patient was treated with steroid pulse therapy (methylprednisolone 1 g/day × 3 days) under a blood sugar control regimen in consultation with an endocrinologist, after which additional peribulbar injection of triamcinolone acetonide (40 mg) was performed. Resolution of the anterior uveitis and the dacryoadenitis was obtained after 2 months and there was no recurrence 1 year after the therapy. This is a rare case of severe anterior uveitis caused by idiopathic dacryoadenitis in a patient with diabetes mellitus. PMID:21654891

    To study the sensitivity of laser flare photometry (LFP) in monitoring anterior chamber inflammation by correlating LFP measurements with slit-lamp evaluation of aqueous cells in HLA-B27-related uveitis in a prospective trial. Slit-lamp cell evaluation was correlated with LFP-measured flare in a masked fashion in HLA-B27-related uveitis patients receiving standard topical therapy. At the time of 50 and 90% LFP flare reduction, the corresponding reduction of cells was recorded and statistically compared using the sign test. Forty-three episodes (in 43 patients) of acute anterior HLA-B27-related uveitis were included. LFP flare reduction and slit-lamp cell reduction were strongly correlated. LFP was significantly more sensitive for both 50% (P = 0.001) and 90% (P = 0.02) LFP flare reduction in assessing the decrease of anterior chamber inflammation. LFP was superior to slit-lamp cell evaluation in monitoring anterior chamber inflammation in uveitis. Flare, becoming a quantitative parameter when measured by LFP, rather than cells, should be considered the gold standard to measure anterior chamber inflammation in uveitis.

    Uveitis, the pathologic condition of inflammation of the uvea, frequently leads to severe vision loss and blindness. S100A8 is a calcium-binding protein which mainly expresses in granulocytes and monocytes and plays a prominent role in the regulation of inflammatory processes and immune response. Here, we determined the role of S100A8-positive cells in acute anterior uveitis (AAU) and keratitis. In rat models of endotoxin (lipopolisaccharide, LPS) -induced uveitis (EIU) and keratitis, S100A8-positive granulocytes and monocytes increased significantly in the iris-ciliary body and cornea as well as in the blood. Interestingly, Glucocorticoids slightly increased S100A8 levels in leukocytes, but reduced its presence significantly in the iris-ciliary body after LPS injection. Moreover, inhibition of NF-kB activation remarkably suppressed both progression of AAU and total S100A8 levels in leukocytes and the iris-ciliary body after LPS administration. Additionally, S100A8 protein level was also found to be elevated in the serum of AAU patients parallel with the progression of AAU through the designated clinical stages. Thus, S100A8 plays a pivotal role in the processes of AAU through involvement in migration and infiltration of S100A8-positive cells. Our findings suggest that serum levels of S100A8 protein can be used to monitor inflammatory activity in AAU. PMID:27786310

    To determine the incidence of and associated risk factors for uveitis after cataract surgery. A total of 17,757 eyes were identified and records of 42 eyes that developed uveitis and 2320 eyes that did not were reviewed. Postsurgical uveitis was defined as persistent inflammation for ≥ 6 months after surgery. Forty-two eyes of 35 patients developed uveitis (0.24%). Eleven patients underwent consecutive cataract surgery but developed unilateral uveitis, and intraoperative complications occurred in 55% of uveitic eyes compared to 0% in fellow eyes (p < 0.05). Median duration of inflammation was 8 and 11.5 months in eyes with and without vitrectomy (p < 0.05). Intraocular complications occurred in 44 and 8.3% of eyes that did and did not develop uveitis, respectively (p = 0.01). Postsurgical uveitis developed after approximately 1 in 400 cataract surgeries and occurred more frequently in eyes experiencing intraoperative complications.

    Background: Spondyloarthritis (SpA) is associated with an array of peripheral manifestations. Our study aims to evaluate extra-articular manifestations of SpA in a Romanian academic clinical setting and to observe their associations with different disease measures. Methods: The study was designed to note the extra-articular manifestations of SpA patients in a cross-sectional and retrospective manner. Records included demographics, inflammation markers, SpA clinical characteristics, treatment regimes, associated osteoporosis and cardiovascular morbidity. Data were assessed by using appropriate non-parametric tests. Results: A total of 126 SpA patients were included. The most common extra-articular manifestations were skin involvement in the form of psoriasis (34.1%), eye involvement in the form of acute anterior uveitis (8.7%) and dactylitis (7.2%). Compared to patients with no record of uveitis, uveitis-affected cases were more frequently males, more frequently diagnosed with ankylosing spondylitis, but less frequently dyslipidemic and diagnosed with psoriasis. Psoriasis-affected patients were older and had a higher prevalence of peripheral SpA diagnosis, but a lower prevalence of radiographic sacroiliitis. Conclusions:Acute anterior uveitis in SpA predominantly affects males with AS. This is relevant both to clinical and fundamental science, since its management requires both ophthalmology and rheumatology clinical settings. Psoriasis was associated more frequently with peripheral SpA.

    The purpose of this study was to evaluate the cytokine expression profile of specific IL-1 family members in the aqueous humor and sera of patients with HLA-B27 associated acute anterior uveitis (AAU) and idiopathic AAU. Following informed consent, a total of 13 patients with HLA-B27 associated AAU, 12 patients with idiopathic AAU and 9 controls were recruited to this study from May 2013 to July 2014. Each individual received a complete ophthalmologic examination. Aqueous humor and sera samples were collected and 11 inflammation-related cytokines of the IL-1 family (IL-1α, IL-1β, IL-1 receptor antagonist [IL-1Ra], IL-18, IL-36 receptor antagonist [IL-36Ra], IL-33, IL-36α, IL-36β, IL-36γ, IL-37, IL-38) were quantitatively measured and analyzed for statistical significance between groups. The degree of inflammation, anterior chamber cell or flare, correlated with expression of IL-1β, IL-1Ra, and IL-18. The highest levels of IL-1β, IL-1Ra, IL-18, and IL-36Ra were seen in the aqueous of patients with HLA-B27 associated AAU and this was statically significant when compared to the controls, but not to idiopathic AAU. Expression of IL-18 was statistically higher in the aqueous of patients with HLA-B27 associated AAU in comparison to either idiopathic AAU or controls, but this may reflect greater inflammation in this patient group. In the sera only IL-1α was statistically higher in the HLA-B27 associated AAU in comparison to the control. Cytokine analysis reveals elevation of multiple IL-1 family members in the aqueous humor of patients with AAU as compared to controls. The specific signature of inflammation may potentially be useful in developing new future therapies for AAU. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To evaluate cytokine expression profile in aqueous humor and sera in patients with HLAB27 associated acute anterior uveitis (AAU) and idiopathic AAU. Twenty patients with AAU and 17 controls were recruited from August 2012 to March 2013. Study subjects with uveitis were divided into two groups: 9 patients with idiopathic AAU and 11 patients with HLA-B27 associated AAU. Complete ophthalmological examinations were performed and clinical features of each group were clearly documented. Aqueous humor and sera were collected and the concentration of 15 immune mediators (IL-1β, IL-4, IL-6, IL-10, IL-17A, IL-17F, IL-21, IL-22, IL-23, IL-25, IL-31, IL-33, TNF-α, IFN-γ, sCD40L) were measured in both aqueous humor and sera simultaneously by multiplex immunoassay. There were significantly higher levels of multiple cytokines in aqueous humor in patients with uveitis compared to controls, including IL-1β, IL-6, IL-10, IL-17a, IL-17f, IL-21, IL-25, IL-31, IFN-γ, TNF-α, and sCD40L. The levels of IL-17a in aqueous humor correlated significantly with disease activity in patients with idiopathic AAU, while the level of IFN-γ in aqueous humor correlated significantly with disease activity in patients with HLA-B27 associated AAU. There was no significant difference in serum cytokine expression between uveitis patients and controls except IL-6, elevated in patients with both idiopathic and HLA-B27 associated AAU. Cytokine expression pattern in the aqueous humor, in contrast to that in serum, may reflect intraocular immune reactions during active inflammation in patients with AAU. Both Th1 and Th17 are involved in immunopathogenesis of HLA-B27 associated and idiopathic AAU, but a different cytokine pattern was identified in these two clinical entities. A predominant Th17-driven immune response may play an important role in the immunopathogenesis of idiopathic AAU, while Th1 dominant immune response may be responsible for the inflammation in HLA-B27 associated AAU.

    2015-06-01

    Uveitis is a common complication of spondyloarthritis. The "phenotype" of the uveitis characteristic of ankylosing spondylitis (sudden onset, anterior, unilateral, recurrent, more often male) may differ from the phenotype often seen with either psoriatic arthritis or inflammatory bowel disease (insidious onset, anterior and intermediate, bilateral, chronic, and/or more often female). The frequency of uveitis is also much greater in association with ankylosing spondylitis than with either inflammatory bowel disease or psoriasis. Uveitis may affect the choice of therapy and can rarely be a complication of therapy. Uveitis and arthritis also co-exist in several animal models.

    Defined as an intraocular inflammation, uveitis may be linked to a systemic disease or represent an isolated entity. Screening for associated extra-ocular manifestations is mandatory in uveitis patients. The localisation of inflammation may be uni- or bilateral, anterior, intermediate or diffuse (panuveitis). Other main elements of the evaluation are the acute or chronic mode and the detection of a granulomatous presentation. In some cases, the examination of intraocular structures may be enough for the diagnosis of uveitis. When a correct approach is taken to the diagnosis of uveitis, causes are identified in approximately 50% of cases and presumed in 25% of patients; in one-fourth of cases, the origin of inflammation remains idiopathic.

Retrospective observational clinical record review of pediatric children with diagnosis of uveitis. In total, 310 children were evaluated, 51.9% were female, mean age of 10.1 years. Posterior uveitis was the most common location (58.7%), of insidious onset (87.4%) and chronic course (78.1%). The most common etiology was infection (58.4%) caused by toxoplasmosis (76.8%). There was a statistically significant difference in visual acuity between anterior (20/68) and intermediate uveitis (20/70), compared with posterior uveitis (20/434) (p<0.05). This is the first study to report the clinical features of pediatric uveitis in Colombia, where infectious etiologies are the leading cause. It will improve awareness and knowledge of pediatric uveitis in developing countries, and contribute to the development of public health policies of pediatric visual health.

    2015-01-01

    Intermediate uveitis is a subset of intraocular inflammation where vitritis is the most consistent sign, with or without snowball opacities or snow banks over the pars plana. Some patients will have an associated underlying systemic disease such as sarcoidosis, multiple sclerosis, ocular tuberculosis, inflammatory bowel disease, possibly Behçet's disease and intraocular lymphoma, whereas some will be classified as pars planitis in case of the lack of an identifiable systemic disease association. Our patient, a 47-year-old woman, developed intermediate uveitis after cataract surgery in her right eye, was misdiagnosed as pars planitis, and received steroid monotherapy for 8 months. Her inflammation only fully resolved after vitrectomy with removal of the intraocular lens (IOL) and capsular bag. Oral fluconazole and intravitreal amphotericin B injection had failed to resolve her inflammation when Candida albicans was identified as the cause of her persistent intermediate uveitis.

    Purpose To develop anterior segment spectral-domain optical coherence tomography (SD-OCT) and quantitative image analysis for use in experimental uveitis in rats. Methods Acute anterior uveitis was generated in Lewis rats. A spectral domain anterior segment OCT system was used to image the anterior chamber (AC) and ciliary body at baseline and during peak inflammation 2 days later. Customized MatLab image analysis algorithms were developed to segment the AC, count AC cells, calculate central corneal thickness (CCT), segment the ciliary body and zonules, and quantify the level of ciliary body inflammation with the ciliary body index (CBI). Images obtained at baseline and during peak inflammation were compared. Finally, longitudinal imaging and image analysis was performed over the 2-week course of inflammation. Results Spectral-domain optical coherence tomography identifies structural features of inflammation. Anterior chamber cell counts at peak inflammation obtained by automated image analysis and human grading were highly correlated (r = 0.961), and correlated well with the histologic score of inflammation (r = 0.895). Inflamed eyes showed a significant increase in average CCT (27 μm, P = 0.02) and an increase in average CBI (P < 0.0001). Longitudinal imaging and quantitative image analysis identified a significant change in AC cell and CBI on day 2 with spontaneous resolution of inflammation by day 14. Conclusions Spectral-domain optical coherence tomography provides high-resolution images of the structural changes associated with anterior uveitis in rats. Anterior chamber cell count and CBI determined by semi-automated image analysis strongly correlates with inflammation, and can be used to quantify inflammation longitudinally in single animals.

    Objective STAT4 and IL23R loci represent common susceptibility genetic factors in autoimmunity. We decided to investigate for the first time the possible role of different STAT4/IL23R autoimmune disease-associated polymorphisms on the susceptibility to develop non-anterior uveitis and its main clinical phenotypes. Methods Four functional polymorphisms (rs3821236, rs7574865, rs7574070, and rs897200) located within STAT4 gene as well as three independent polymorphisms (rs7517847, rs11209026, and rs1495965) located within IL23R were genotyped using TaqMan® allelic discrimination in a total of 206 patients with non-anterior uveitis and 1553 healthy controls from Spain. Results No statistically significant differences were found when allele and genotype distributions were compared between non-anterior uveitis patients and controls for any STAT4 (rs3821236: P=0.39, OR=1.12, CI 95%=0.87-1.43; rs7574865: P=0.59 OR=1.07, CI 95%=0.84-1.37; rs7574070: P=0.26, OR=0.89, CI 95%=0.72-1.10; rs897200: P=0.22, OR=0.88, CI 95%=0.71-1.08;) or IL23R polymorphisms (rs7517847: P=0.49, OR=1.08, CI 95%=0.87-1.33; rs11209026: P=0.26, OR=0.78, CI 95%=0.51-1.21; rs1495965: P=0.51, OR=0.93, CI 95%=0.76-1.15). Conclusion Our results do not support a relevant role, similar to that described for other autoimmune diseases, of IL23R and STAT4 polymorphisms in the non-anterior uveitis genetic predisposition. Further studies are needed to discard a possible weak effect of the studied variant. PMID:24312163

    The blood-aqueous barrier (BAB) permeability was studied by fluorophotometry in 17 healthy control subjects and in 27 eyes from 27 patients with HLA-B27-positive acute anterior uveitis (HLA-B27 AAU). Twenty of these patients had an associated spondyloarthropathy. BAB permeability was studied during the ocular inflammatory crisis and in the disease-free periods in the same patients. Anterior chamber fluorophotometric scans were performed before and 30 minutes after the intravenous injection of 14 mg/kg of sodium fluorescein. The diffusion coefficient (Kd) was obtained from the ratio between the fluorescein concentration in the anterior chamber and the NPBF. Data were analyzed using the Student's t test and analysis of variance. A statistically significant difference (P < 0.001) was found between the Kd of active HLA-B27 AAU (61.4 +/- 16.8 x 10(-4) min-1) and the Kd of inactive HLA-B27 AAU (4.8 +/- 1.6 x 10(-4) min-1). No statistically significant differences were found between the Kd of inactive HLA-B27 AAU and the Kd of the control subjects (4.3 +/- 1.0 x 10(-4) min-1). We also failed to detect significant differences between patients with and without spondyloarthropathy either during the acute attack or during the disease-free period. On the basis of these results we conclude that the permeability of the BAB remains intact in inactive HLA-B27-positive AAU. The parallel fluorophotometric behaviour of HLA-B27-positive AAU with spondyloarthropathy and without spondyloarthropathy suggests that both share a common pathogenetic mechanism.

    We investigated the vision-related quality of life (VR-QOL) and the prevalence and severity of depression in patients with herpetic anterior uveitis (AU). This study was conducted in 2012 at the ophthalmology department of the University Medical Center of Groningen (tertiary referral center). We selected patients from an existing uveitis database, all eligible patients were approached. Thirty-six of 66 (55%) patients with herpetic AU (herpes simplex virus or varicella zoster virus) participated, patients were 18 years or older. The diagnosis was made by clinical presentation or a positive anterior chamber tap. All patients received an information letter, informed consent form, National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25), Beck Depression Inventory (BDI-II), Social Support List – Interactions (SSL-I), Social Support List – Discrepancies (SSL-D) and an additional questionnaire for gathering general information. Medical records were reviewed for clinical characteristics. Analyses were conducted on various patient and ocular characteristics. We compared our NEI VFQ-25 scores with those previously found in the literature. Our main outcome measures were VR-QOL, prevalence and severity of depression, social support and various patient and ocular characteristics that could influence the VR-QOL. We found that the NEI VFQ-25 mean overall composite score (OCS) was 88.1±10.6. Compared with other ocular diseases our OCS is relatively high, but lower than that found in a normal working population. The mean general health score was 59.0±19.0; this score is lower than in patients with other ocular diseases, except for untreated Behçet’s patients. Depression was scarce, with only one patient (2.8%) having a moderate depression (BDI-II score of 21). We concluded that herpetic AU affects the VR-QOL in a moderate way. The prevalence of depression in our group of herpetic AU patients was low and therefore does not seem to indicate a need for specific

    The uveitogenicity of melanin has been a controversial subject for a long time, presumably as a result of the use of ill-defined preparations in the experiments. We have developed procedures for the preparation of purified uveitogenic melanins from the retinal pigment epithelium and choroid that are free from pathogenic retinal photoreceptor proteins. The active melano-antigen is located at the surface of the melanin granules and is probably identical in both tissues. It retains its pathogenicity in hot polar detergent and during in vitro proteolysis, but it is inactivated by macrophage phagocytosis and hydrolysis in hot hydrochloric acid. Lewis rats immunized with microgram doses of bovine retinal pigment epithelial or choroidal melanin develop severe experimental autoimmune anterior uveitis (EAAU) about 10 days later. Retinitis and pinealitis are not observed. Skin melanin prepared in a similar way evokes EAAU as well, but it is only weakly pathogenic. EAAU cannot be transferred by serum, and its development can effectively be inhibited by antibodies to the inciting antigen and by cyclosporin. Vitamin E treatment of the animals causes a delay in its onset. The results indicate that cell-mediated immunity plays a dominant role in the pathogenesis of EAAU. This is the first time it has been shown that purified ocular and skin melanins are able to induce an autoimmune disease. The relevance of this finding for the study of melanin-related immunopathology in man is discussed.

    Objective: To study the infectious backround of patients with a history of acute anterior uveitis (AAU) and healthy control subjects. Methods: Sixty four patients with previous AAU and 64 sex and age matched controls were studied. Serum antibodies to Salmonellae, Yersiniae, Klebsiella pneumoniae, Escherichia coli, Proteus mirabilis, Campylobacter jejuni, and Borrelia burgdorferi were measured using enzyme linked immunosorbent assay (ELISA), and antibodies to Chlamydia trachomatis and Chlamydia pneumoniae by microimmunofluorescence test. Peripheral blood mononuclear cells (PBMCs), separated by density gradient centrifugation, were studied for Salmonella and Yersinia antigens by means of an immunofluorescence test, and for C pneumoniae DNA with a polymerase chain reaction (PCR). Results: Neither prevalence nor levels of single microbial antibodies studied differed between the patients and control subjects, or between subgroups of patients created on the basis of clinical characteristics. In logistic regression analysis, the high number of recurrences (>10) of AAU was independently related to the presence of single or multiple bacterial antibodies (p=0.04). None of the PBMC samples of the patients were positive for Yersinia or Salmonella antigens. C pneumoniae PCR was positive in a patient who was negative for C pneumoniae antibodies. Conclusion: Although neither the prevalence nor the levels of single microbial antibodies studied differed between the patients and the controls, current data suggest that the presence of single or multiple antibodies in patients with many recurrences of AAU compared with patients with none or few recurrences may be a sign of repeated infections, antigen persistence, or raised innate immune responsiveness.

    Rheumatologists may need to establish the etiological diagnosis and handle the therapeutic management of adults with uveitis. To date, no diagnostic strategy for uveitis has been validated by prospective studies. Investigations are selected based on the clinical features and on the anatomic location of the ocular abnormalities. Infections such as syphilis, Lyme disease, tuberculosis, and Whipple's disease may cause uveitis, with concomitant joint inflammation in a few cases. In patients with a known history of chronic inflammatory joint disease, causes of uveitis include bisphosphonate therapy and immunodepression-related infections (e.g., due to Toxoplasma or a herpes virus). Sarcoidosis is an underestimated cause of uveitis, which occurs in 15% of cases, with a predilection for middle-aged women. In spondyloarthritis, uveitis is almost always acute, unilateral, and anterior. Among patients with uveitis and spondyloarthritis, about two thirds have their joint disease diagnosed during an evaluation for uveitis. Therefore, patients with inflammatory or noninflammatory back pain should be routinely evaluated for spondyloarthritis, which is the leading cause of uveitis in western countries. The risk of blindness is extremely low, and the main complication is recurrent uveitis, seen in 50% to 60% of cases. Sulfasalazine decreases the frequency, duration, and severity of uveitis and can be used prophylactically.

    The following report describes the direct detection of Ehrlichia canis by real-time PCR in the conjunctiva of a 1-year-old female Maltese dog. After being imported from Brazil, the dog was presented because of anorexia, dehydration, fever, and palpable mandibular lymph nodes. A few days later, the dog developed bilateral blepharospasm, photophobia and anterior uveitis. Monocytic ehrlichia was diagnosed by a positive PCR result and the detection of IgM and IgG antibodies. Because of the massive uveitis a conjunctival sample was taken with a cytobrush, which also tested positive for Ehrlichia canis DNA by real-time PCR. Only one week after starting treatment with systemic doxycycline and local anti-inflammatory and cyclopalgic therapy the dog recovered from systemic and eye diseases. After therapy the follow-up examination revealed a full remission of clinical and hematological parameters and negative PCR result.

    Objective Interferon (IFN) signaling plays a crucial role in autoimmunity. Genetic variation in interferon regulatory factor 5 (IRF5), a major regulator of the type I interferon induction, has been associated with risk of developing several autoimmune diseases. In the current study we aimed to evaluate whether three sets of correlated IRF5 genetic variants, independently associated with SLE and with different functional roles, are involved in uveitis susceptibility and its clinical subphenotypes. Methods Three IRF5 polymorphisms, rs2004640, rs2070197 and rs10954213, representative of each group, were genotyped using TaqMan® allelic discrimination assays in a total of 263 non-anterior uveitis patients and 724 healthy controls of Spanish origin. Results A clear association between two of the three analyzed genetic variants, rs2004640 and rs10954213, and the absence of macular edema was observed in the case/control analysis (PFDR=5.07E-03, OR=1.48, CI 95%=1.14-1.92 and PFDR=3.37E-03, OR=1.54, CI 95%=1.19-2.01, respectively). Consistently, the subphenotype analysis accordingly with the presence/absence of this clinical condition also reached statistical significance (rs2004640: P=0.037, OR=0.69, CI 95%=0.48-0.98; rs10954213: P=0.030, OR=0.67, CI 95%=0.47-0.96), thus suggesting that both IRF5 genetic variants are specifically associated with the lack of macular edema in uveitis patients. Conclusion Our results clearly showed for the first time that two functional genetic variants of IRF5 may play a role in the development of macular edema in non-anterior uveitis patients. Identifying genetic markers for macular edema could lead to the possibility of developing novel treatments or preventive therapies. PMID:24116155

    To compare clinical findings and the aqueous levels of inflammatory mediators between toxic anterior segment syndrome (TASS) and endotoxin-induced uveitis (EIU) animal models and to evaluate the efficacy of systemic steroid pretreatment in both animal models. Rats were used in this study. Ortho-phthalaldehyde solution was injected into the anterior chamber to produce TASS (n=30), and lipopolysaccharide was injected into one hind footpad to produce EIU (n=30). Clinical findings were evaluated under slit-lamp examination, and the aqueous levels of prostaglandin E2 (PGE2) and tumor necrosis factor-α (TNF-α) were measured 24 hours after these procedures. Twelve of the rats in each animal model were pretreated with intraperitoneal injection of dexamethasone for 4 days before the development of TASS and EIU. Corneal haze scores were significantly higher for TASS than EIU, but clinical scores for anterior uveitis were not different between the two animal models. Although aqueous levels of PGE2 were markedly increased in both animal models, PGE2 levels were significantly higher for TASS than for EIU. However, an increase in aqueous levels of TNF-α was observed only in EIU. Dexamethasone pretreatment reduced the corneal haze score and clinical score for anterior uveitis in both animal models and inhibited the increase in aqueous levels of PGE2 and TNF-α. Prostaglandin E2 and TNF-α in aqueous humor seem to be regulated differently in animal models of TASS and EIU. However, dexamethasone pretreatment improved the clinical findings and inhibited the increases in PGE2 and TNF-α in both animal models.

    Purpose Evaluation of peripheral retinal vascular changes in anterior uveitis using ultra-wide-field fluorescein angiography. Design A prospective, observational study of a case series of patients diagnosed with anterior uveitis. Methods Setting: Clinical observation at an academic medical center. Patient or Study Population: A total of 65 eyes of 33 patients corresponded with the research criteria of anterior uveitis in the opinion of specialists of Peking University First Hospital. Observation Procedures: Patients were diagnosed primarily through clinical examinations and conventional fluorescein angiography. Subsequently, ultra-wide-field fluorescein angiograms were obtained for each patient. Main Outcome Measures: The main outcome was the detection of peripheral retinal changes by ultra-wide-field fluorescein angiography, and how these changes influenced the evaluation and management of the disease. Results Peripheral vessel leakage was detected in 27 eyes (42%) with anterior uveitis, of which 15 eyes displayed active inflammation and 12 eyes displayed inactive inflammation. Peripheral vessel leakage was found in seven of eight eyes with cystoid macular edema. Cystoid macular edema was detected in 7 of 27 eyes (26%) with peripheral vessel leakage, whereas 1 of 38 eyes (3%) did not display peripheral vessel leakage (p<0.01). 44.4% of the patients with peripheral vessel leakage had a specific etiology. The relevant treatment strategies were modified based on the results of the ultra-wide-field fluorescein angiography. 12 patients with peripheral vessel leakage and a quiescent anterior segment were added to those receiving topical glucocorticoids, while 3 patients with serious peripheral vessel leakage and an active anterior segment received a sub-Tenon injection of triamcinolone acetonide. Conclusions Ultra-wide-field fluorescein angiography was very effective in detecting peripheral retinal vascular pathology in anterior uveitis. The changes found in the

    Background Juvenile idiopathic arthritis is the most common rheumatic disease in children. Chronic uveitis is a common and serious comorbid condition of juvenile idiopathic arthritis, with insidious presentation and potential to cause blindness. Knowledge of clinical associations will improve risk stratification. Based on clinical observation, we hypothesized that allergic conditions are associated with chronic uveitis in juvenile idiopathic arthritis patients. Methods This study is a retrospective cohort study using Stanford’s clinical data warehouse containing data from Lucile Packard Children’s Hospital from 2000–2011 to analyze patient characteristics associated with chronic uveitis in a large juvenile idiopathic arthritis cohort. Clinical notes in patients under 16 years of age were processed via a validated text analytics pipeline. Bivariate-associated variables were used in a multivariate logistic regression adjusted for age, gender, and race. Previously reported associations were evaluated to validate our methods. The main outcome measure was presence of terms indicating allergy or allergy medications use overrepresented in juvenile idiopathic arthritis patients with chronic uveitis. Residual text features were then used in unsupervised hierarchical clustering to compare clinical text similarity between patients with and without uveitis. Results Previously reported associations with uveitis in juvenile idiopathic arthritis patients (earlier age at arthritis diagnosis, oligoarticular-onset disease, antinuclear antibody status, history of psoriasis) were reproduced in our study. Use of allergy medications and terms describing allergic conditions were independently associated with chronic uveitis. The association with allergy drugs when adjusted for known associations remained significant (OR 2.54, 95% CI 1.22–5.4). Conclusions This study shows the potential of using a validated text analytics pipeline on clinical data warehouses to examine practice

    Objective To use high density genotyping to investigate the genetic associations of acute anterior uveitis (AAU) in patients both with and without ankylosing spondylitis (AS). Method We genotyped 1,711 patients with AAU (either primary or with AAU and AS), 2,339 AS patients without AAU, and 10,000 controls on the Illumina Immunochip Infinium microarray. We also used data on AS patients from previous genomewide association studies to investigate the AS risk locus ANTXR2 for its putative effect in AAU. ANTXR2 expression in mouse eyes was investigated by RT-PCR. Results Comparing all AAU cases with HC, strong association was seen over HLA-B corresponding to the HLA-B27 tag SNP rs116488202. Three non-MHC loci IL23R, the intergenic region 2p15 and ERAP1 were associated at genome-wide significance (P < 5×10−8). Five loci harboring the immune-related genes IL10-IL19, IL18R1-IL1R1, IL6R, the chromosome 1q32 locus harboring KIF21B, as well as the eye related gene EYS, were also associated at a suggestive level of significance (P < 5×10−6). A number of previously confirmed AS associations demonstrated significant differences in effect size between AS patients with AAU and AS patients without AAU. ANTXR2 expression was found to vary across eye compartments. Conclusion These findings, with both novel AAU specific associations, and associations shared with AS demonstrate overlapping but also distinct genetic susceptibility loci for AAU and AS. The associations in IL10 and IL18R1 are shared with inflammatory bowel disease, suggesting common etiologic pathways. PMID:25200001

    Lewis rats immunized with myelin basic protein (MBP) develop experimental autoimmune encephalomyelitis (EAE) and associated anterior uveitis (AU). Rats recover and become resistant to further reinduction of EAE. We investigated whether the resistance to reinduction of EAE was associated with the resistance to AU in LEW rats reinjected with MBP. We demonstrated that while rats remained resistant to EAE, they become susceptible to uveitis after recovery, and suffered a second episode of disease. The susceptibility to reinduced disease was associated with the recognition of new MBP epitopes. In contrast to the initial episode of AU, TCR Vbeta8.2 predominance was not observed in the iris/ciliary body. Our results suggest that T cells specific for MBP, which are rapidly reactivated when re-exposed to antigen, are sufficient to induce clinical uveitis in LEW rats. This process may involve a shifting of T cell specificity from the major encephalitogenic peptide utilizing the Vbeta8.2 receptor to a more diverse cell repertoire.

    There is no updated information on epidemiology and cost of management of non infectious uveitis (NIU) in Spain. This study assessed the frequency of various types of uveítis as well as associated costs of resources used in their management. NIU epidemiological data and direct costs were collected from a literature search. This was complemented with consensus information from 2 expert panel meetings and data from questionnaires to ophthalmologists and rheumatologists, experts on these conditions. Healthcare resources costs were obtained from the Oblikue database, from a medical society and from approved drug prices in Spain. During 2011 the estimate number of NIU was 9,398 (45% male, 70% aged 16-65 years). Incidence per type of uveitis was: acute anterior uveitis (AAU) 55%; posterior uveitis (PU) and pan-uveitis (PanU) 15% each; adult chronic anterior uveitis, paediatric chronic anterior uveitis and intermediate uveitis 5% each. Among total costs (77,834,282.10€), initial drug therapy was the highest (43,602,359.29€), followed by surgical treatment of complications (8,367,420.43€). With respect to types of uveitis, PanU (26,692,948.29€), PU (22,283,330.50€) and AAU (14,336,755.38€) showed the highest associated costs. Non infectious uveitis is associated to high costs in Spain, both in its diagnosis and in its treatment. Early diagnosis and treatment should allow for substantial savings for the National Health System.

    To develop a combination surgery for wet age-related macular degeneration and concurrent chronic peripheral uveitis that would include intravitreal injection of Lucentis and cryocerclage of the peripheral retina. A total of 75 patients were examined and divided into 2 groups: the main group (37 patients) and the controls (38 patients). Patients from the main group underwent the new combination surgery, while the controls received intravitreal Lucentis alone (peripheral uveitis was managed therapeutically). It has been found that the new combination method provides a significant and stable improvement in visual acuity (by a factor of 10) and a decrease in the area of central scotoma (by a factor of 2.95) in the postoperative period. The period needed for recovery in the central retinal thickness is also 1.6 times shorter. The new combination surgery for wet age-related macular degeneration and concurrent chronic peripheral uveitis provides rapid reduction of inflammation in the extreme periphery of the fundus and a 1.5 times faster (as compared to traditional methods) primary restoration of topographic anatomy of the retina in the macular region.

    Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease of childhood, with JIA-associated uveitis its most common extra-articular manifestation. JIA-associated uveitis is a potentially sight-threatening condition and thus carries a considerable risk of morbidity. The aetiology of the condition is autoimmune in nature with the predominant involvement of CD4(+) T cells. However, the underlying pathogenic mechanisms remain unclear, particularly regarding interplay between genetic and environmental factors. JIA-associated uveitis comes in several forms, but the most common presentation is of the chronic anterior uveitis type. This condition is usually asymptomatic and thus screening for JIA-associated uveitis in at-risk patients is paramount. Early detection and treatment aims to stop inflammation and prevent the development of complications leading to visual loss, which can occur due to both active disease and burden of disease treatment. Visually disabling complications of JIA-associated uveitis include cataracts, glaucoma, band keratopathy and macular oedema. There is a growing body of evidence for the early introduction of systemic immunosuppressive therapies in order to reduce topical and systemic glucocorticoid use. This includes more traditional treatments, such as methotrexate, as well as newer biological therapies. This review highlights the epidemiology of JIA-associated uveitis, the underlying pathogenesis and how affected patients may present. The current guidelines and criteria for screening, diagnosis and monitoring are discussed along with approaches to management.

    Uveitis are a large group of inflammatory diseases involving the iris, the ciliary body and the uvea. Multiple causes can be responsible for ocular inflammation that can result either from infectious or autoimmune disease. The incidence varies from 14 to 28/100,000 habitants. According to the anatomical classification, about 30-60% (average 47%) are related to anterior uveitis. 6-30% average 21%) are posterior uveitis, 7-15% (average 12%) are intermediate uveitis and 7-69% (average 20%) are panuveitis. A specific diagnostic can be established in more than 70% in most series. The most frequently diagnosed entities are HLA-B27 related uveitis, acute anterior uveitis in herpes zoster disease, toxoplasmosis, sarcoidosis and pars planitis.

    To describe the clinical presentation of uveitis with coincident onset of raised and indurated tattooed skin. Case series. Seven consecutive patients were evaluated at a tertiary ophthalmologic facility with coincident uveitis and cutaneous tattoo induration over an 18-month period. All subjects underwent complete ophthalmic examination and a focused systemic medical evaluation including serologic testing and imaging studies. Two participants underwent biopsy of their tattoos. The patients' clinical courses and responses to treatment over a follow-up period of 1-20 months are reported (mean follow-up = 9 months). Main outcome measures included degree of intraocular inflammation, ocular complications, visual acuity, clinically observable tattooed skin changes, and biopsy results. Five of 7 patients had bilateral nongranulomatous anterior uveitis: 4 with chronic and 1 with recurrent disease. The remaining 2 patients had bilateral chronic granulomatous panuveitis. Biopsies of raised and indurated tattoos were performed in 2 patients and demonstrated noncaseating granulomatous inflammation surrounding tattoo ink in the dermis. The skin changes resolved in all patients, with a faster response noted in those treated with high-dose oral prednisone for intraocular inflammation. Five patients subsequently experienced recurrent flares of intraocular inflammation in conjunction with the recurrence of raised and indurated tattoos. These cases represent a subset of patients in whom skin tattooing may have incited an immune response leading to simultaneous inflammation of the eyes and tattooed skin.

    Targeted drug delivery to the ocular tissues remains a challenge. Biodegradable intraocular implants allow prolonged controlled release of drugs directly into the eye. In this study, we evaluated an anterior suprachoroidal polyurethane implant containing dexamethasone polyurethane dispersions (DX-PUD) as a drug delivery system in the rat model of endotoxin-induced uveitis (EIU). In vitro drug release was studied using PUD implants containing 8%, 20%, and 30% (wt/wt) DX. Cytotoxicity of the degradation products of DX-PUD was assessed on human ARPE-19 cells using 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide (MTT) test. Short-term ocular biocompatibility of suprachoroidal DX-PUD implants was evaluated in normal rat eyes. Endotoxin-induced uveitis was then induced in rat eyes preimplanted with DX-PUD. Clinical examination was performed at 24 hours; eyes were used to assess inflammatory cell infiltration and macrophage/microglial activation. Cytokine and chemokine expression in the iris/ciliary body and in the retina was investigated using quantitative PCR. Feasibility of anterior suprachoroidal PUD implantation was also tested using postmortem human eyes. A burst release was followed by a sustained controlled release of DX from PUD implants. By-products of the DX-PUD were not toxic to human ARPE-19 cells or to rat ocular tissues. Dexamethasone-PUD implants prevented EIU in rat eyes, reducing inflammatory cell infiltration and inhibiting macrophage/microglial activation. Dexamethasone-PUD downregulated proinflammatory cytokines/chemokines (IL-1β, IL-6, cytokine-induced neutrophil chemoattractant [CINC]) and inducible nitric oxide synthase (iNOS) and upregulated IL-10 anti-inflammatory cytokine. Polyurethane dispersion was successfully implanted into postmortem human eyes. Dexamethasone-PUD implanted in the anterior suprachoroidal space may be of interest in the treatment of intraocular inflammation.

    The aim of our study is to investigate the long-term transitions of intraocular pressure (IOP) and aqueous flare values in uveitis patients with faint anterior chamber flare who were treated with once-daily topical ophthalmic betamethasone for more than 6 months. The study included a total of 111 eyes of 68 outpatients. The mean follow-up period was 26.8 months. The average IOP and aqueous flare value of patients divided by the 5-months follow-up period showed no significant difference. Six eyes (of four patients) were followed-up for more than 1 year after termination of the treatment. Among these patients, the average aqueous flare value was significantly higher, and the average period to reach more than 1.5 times the former aqueous flare value significantly decreased after termination than before. Once-daily topical ophthalmic betamethasone is not expected to cause steroid-induced ocular hypertension but to have prophylactic effect.

    Hypothesis:Abnormal Vitamin D (Vit D) level could have consequences on the immuno-inflammatory processes in Ankylosing Spondylitis (AS). Aim:The purpose of this study was to analyze the role of Vitamin D in the interplay between immune and inflammation effectors in AS associated-Acute Anterior Uveitis (AAU). Methods and Results:25-hydroxyvitamin D (Vit D), LL-37 peptide, IL-8 and Serum Amyloid A (SAA) were identified and quantified in the serum/ plasma of thirty-four AS patients [eleven AS patients presenting AAU (AAU AS patients) and twenty-three AS patients without AAU (wAAU AS patients)] and eighteen healthy individuals (Control) using enzyme-linked immunosorbent assay. Acute-phase SAA level was significantly higher in AS patients compared to Controls. Contrary with wAAU AS patients, significantly elevated levels of IL-8, and diminished levels of Vit D characterized AAU AS patients. Regarding LL-37, its level decreased concomitantly with the level of Vit D. When AS patients were subgrouped based on AAU presence or on Vit D level, important associations between immuno-inflammatory assessed markers and AS features were noticed. Generally, Vit D levels were associated indirectly with leukocytes/ neutrophils number or with ESR, CRP, and Fibrinogen levels. The levels of SAA and IL-8 associated directly with AAU or with AAU relapses, especially in AS patients with Vit D insufficiency, while SAA associated directly with infection/ inflammatory markers and with disease activity indexes or with the degree of functional limitation. Discussion:Altered levels of Vit D affect the balance between LL-37, IL-8 and SAA, suggesting an association with AAU, an extra-articular manifestation of AS. Abbreviations:Vit D = Vitamin D, AS = Ankylosing Spondylitis, AAU = Acute Anterior Uveitis, AAU AS = AS patients with AAU, wAAU AS = AS patients without AAU, SSZ = Sulphasalazine, Leu = Leukocytes, Neu = Neutrophils.

    To present the long-term results of ab externo trabeculotomy in the management of glaucoma secondary to chronic uveitis. In this retrospective single-centre case series, medical records of patients with glaucoma secondary to chronic uveitis, who underwent ab externo trabeculotomy, were evaluated. Two definitions of success were used: intraocular pressure (IOP) 6 ≤ IOP ≤ 21 mmHg (success 1) or 6 ≤ IOP ≤ 21 mmHg and at least 25 % reduction from baseline (success 2). Success was complete when no additional medication was required or qualified when additional medication or cycloablative procedures were required to achieve the specific IOP definition. Twenty-two eyes of 18 patients were included. After 3 years, median IOP decreased from 27 mmHg [range 17-43 mmHg, mean 27.5 mmHg, 95 % confidence interval of the mean (CI) 24.5-30.5 mmHg] to 15 mmHg (range 9-19 mmHg, mean 14.5 mmHg, CI 13-16.1 mmHg). Complete and qualified success 1 was 23 and 45 % after 3 years, respectively. For success 2, the rates were 23 and 32 %, respectively. Hyphema was the most common complication, which resolved completely within 1 month after surgery without further intervention. Trabeculotomy ab externo was moderately successful in glaucoma secondary to chronic uveitis after 3 years. No sight-threatening complications were observed during the follow-up period.

    Purpose. Endogenous anterior uveitis (AU), when untreated, may lead to vision loss. This study compared the safety and efficacy of difluprednate versus prednisolone acetate for the treatment of this condition. Methods. This phase III, double-masked, noninferiority study randomized patients with mild to moderate endogenous AU to receive difluprednate 0.05% (n = 56) four times daily, alternating with vehicle four times daily, or prednisolone acetate 1% (n = 54) eight times daily. The 14-day treatment period was followed by a 14-day dose-tapering period and a 14-day observation period. The primary efficacy end point was change in anterior chamber cell grade (range, 0 for ≤1 cell to 4 for >50 cells) from baseline to day 14. Results. At day 14, the mean change in anterior chamber cell grade with difluprednate was noninferior to that with prednisolone acetate (−2.2 vs. −2.0, P = 0.16). The proportions of difluprednate-treated patients versus prednisolone acetate–treated patients demonstrating complete clearing of anterior chamber cells at day 3 were 13.0% vs. 2.1% (P = 0.046) and at day 21 were 73.9% vs. 63.8% (P = 0.013). A significant between-group difference in the mean IOP increase was seen at day 3 (2.5 mm Hg for difluprednate-treated patients and 0.1 mm Hg for prednisolone acetate–treated patients, P = 0.0013) but not at other time points. The mean IOP values in both groups remained less than 21 mm Hg throughout the study. Conclusions. Difluprednate 0.05% four times daily is well tolerated and is noninferior to prednisolone acetate 1% eight times daily for the treatment of endogenous AU. (ClinicalTrials.gov number, NCT01201798.)

    To evaluate the differences in the biometric parameters of iridocorneal angle and iris structure measured by anterior segment optical coherence tomography (AS-OCT) in Fuchs' uveitis syndrome (FUS). Seventy-six eyes of 38 consecutive patients with the diagnosis of unilateral FUS were recruited into this prospective, cross-sectional and comparative study. After a complete ocular examination, anterior segment biometric parameters were measured by Visante(®) AS-OCT. All parameters were compared between the two eyes of each patient statistically. The mean age of the 38 subjects was 32.5 ± 7.5 years (18 female and 20 male). The mean visual acuity was lower in eyes with FUS (0.55 ± 0.31) than in healthy eyes (0.93 ± 0.17). The central corneal thickness did not differ significantly between eyes. All iridocorneal angle parameters (angle-opening distance 500 and 750, scleral spur angle, trabecular-iris space (TISA) 500 and 750) except TISA 500 in temporal quadrant were significantly larger in eyes with FUS than in healthy eyes. Anterior chamber depth was deeper in the eyes with FUS than in the unaffected eyes. With regard to iris measurements, iris thickness in the thickest part, iris bowing and iris shape were all statistically different between the affected eye and the healthy eye in individual patients with FUS. However, no statistically significant differences were evident in iris thickness 500 μm, thickness in the middle and iris length. There were significant difference in iris shape between the two eyes of patients with glaucoma. AS-OCT as an imaging method provides us with many informative resultsin the analysis of anterior segment parameters in FUS.

    Cell grading in a rodent anterior chamber is essential for anterior inflammation evaluation in preclinical vision research. This paper describes a computerized method for detection and counting of the anterior chamber cells from swept-source optical coherence tomography (SS-OCT) images of a experimental rodent model of uveitis. The volumetric anterior segment OCT data is obtained from 100 kHz SS-OCT imaging of mouse eye in vivo. For the OCT cross-sections, each OCT structural image is de-speckled and binarized. After removal of cornea, iris, and crystalline lens structures connected to the binary image border, an area thresholding is then employed for each labeled region to isolate only celllike objects in the anterior chamber, followed by roundness estimation of the objects to identify potential cell candidates in the data. Eventually, the cell candidates are counted and graded as total number of cells in the anterior chamber.

    We have compared the anti-inflammatory efficacy of 5% tolmetin sodium dihydrate, 0.5% prednisolone disodium phosphate, and 0.1% betamethasone disodium phosphate in 71 consecutive patients presenting with acute endogenous non-granulomatous uveitis randomly assigned to one of these treatment groups. Inflammatory symptoms and signs were scored during the course of the 21-day trial period. There was no statistically significant difference in the effect on the signs or symptoms of the three drugs tested. 90% of the Betnesol (betamethasone sodium phosphate, benzalkonium chloride) treated group were clinically judged cured compared with 68% of the Predsol (prednisolone sodium phosphate, benzalkonium chloride) treated group, and 57% of the tolmetin treated group.

    Th17 and regulatory T cells, involved in the pathogenesis of several autoimmune diseases, are new lineages of CD4+ T helper cells. However, the role of their imbalance in human leukocyte antigen B27-associated acute anterior uveitis has not been elucidated. In our study, the percentages of Th17 and Treg cells, their molecular markers and related factors in peripheral blood of patients and healthy controls were measured by flow cytometry, real-time RT-PCR and ELISA. We observed a remarkable increase of CD4+ and CD4+IL-17+ T cells in peripheral blood of patients compared to controls. The molecular markers and related factors of Th17 cell were also showed a distinct elevation. Interestingly, we observed an obvious decrease of CD4+CD25+Foxp3+ T cells and Foxp3 mRNA level in patients. The ratio of Th17/Treg in patients was dramatically higher than controls. Moreover, the ratio of Th17/Treg cells had a more significantly positive correlation with the disease activity score than Th17 cells whereas Treg cells had a negative correlation. Our findings demonstrated a distinct increase of Th17 cells and a significant decrease of Treg cells in patients compared to controls. The imbalance of Th17 and Treg cells may play a vital role in the pathogenesis of the disease. PMID:28091550

    AIM To assess the levels of the neutrophil to lymphocyte ratio (N/L) and the platelet to lymphocyte ratio (P/L) in patients with idiopathic acute anterior uveitis (AAU) and to compare with healthy controls. METHODS Thirty-six male patients with idiopathic AAU and 36 male healthy subjects were enrolled in this retrospective study. Complete ophthalmological examination and complete blood count measurements results of all subjects were evaluated. RESULTS There was a significant difference in N/L and P/L between idiopathic AAU and control groups (P=0.006, P=0.022). Also, correlation analysis revealed a significant correlation between C-reactive protein (CRP) and N/L (P=0.002; r=0.461). CONCLUSION Our study for the first time provides evidence of N/L and P/L may be useful biomarkers in patients with idiopathic AAU. N/L is correlated with CRP, so it can be a useful biomarker to predict the prognosis in idiopathic AAU. PMID:28251086

    Purpose. This study aimed to investigate the association between single nucleotide polymorphisms (SNPs) of JAK-STAT signaling pathway genes and acute anterior uveitis (AAU) with or without ankylosing spondylitis (AS) in the Han Chinese population. Methods. Eleven SNPs of the JAK1, JAK2, STAT1, IRF1, and NOS2 genes were analyzed in 443 AAU patients with AS, 486 AAU patients without AS, and 714 healthy controls. Genotyping was performed by PCR-RFLP assay or TaqMan® probe assay. The Chi-squared (χ2) test and multivariate logistic regression analysis were used to compare the distributions of alleles and genotypes between patients and controls. P values were adjusted using Bonferroni correction. Results. We did not observe significant differences in the genotype and allele frequencies of any SNP between AAU patients with or without AS and healthy controls. Stratification analyses by gender and HLA-B27 status showed a boundary significant association between two SNPs (rs10975003 and rs10758669) in JAK2 and AAU (P = 0.052 and P = 0.053, resp.). Conclusions. Our results indicated that genetic polymorphisms of the JAK-STAT signaling pathway genes may not be associated with AAU in the Han Chinese population. PMID:27965977

    Purpose: To determine the clinical features and distribution of uveitis in the pediatric age group at a referral eye care center in Shiraz, South Iran. Materials and Methods: All new cases of uveitis in patients 18-year-old or younger referred from January 2007 to December 2013 were enrolled in this study. The patient underwent a complete history of systemic and ocular diseases, comprehensive ophthalmic examination. Patients were classified according to the International Uveitis Study Group definitions. The definitive diagnosis was based on clinical manifestations and laboratory investigations. Results: Seventy-seven eyes (54 patients) comprised the study sample. The mean age at the onset of uveitis was 12.5 years. The female-to-male ratio was 1.25. Anterior uveitis was the most frequent anatomical location (40.7%), followed by intermediate uveitis (33.3%), posterior uveitis (18.5%), and panuveitis (7.5%). Seventy-four percent of patients presented with chronic uveitis. Noninfectious uveitis (81.5%) was the most frequent etiology. Thirty-seven percent of patients had a specific diagnosis for uveitis, and 63% were classified as idiopathic cases. Toxocariasis was the most common infectious cause. Associated systemic diseases were present in 14.8% of patients. The most frequent systemic disease was juvenile idiopathic arthritis in 9.2% of patients. Complications occurred in 66 (85.5%) of affected eyes. The most common complications were posterior synechia (20.7%), cataract (18.8%), and cystoid macular edema (12.9%). Conclusions: Uveitis in the majority of children had an insidious onset and was chronic. Over half the patients had a specific diagnosis. Idiopathic cases were more common in the intermediate uveitis group. PMID:27555706

    Introduction: In clinical settings, acute anterior uveitis (AAU) could be the first presentation of ankylosing spondylitis (AS). Based on this hypothesis, we investigate whether AAU is a risk factor in developing AS later by using National Health Insurance Research Database (NHIRD) in Taiwan. Materials and Methods: This cohort comparison study used longitudinal Taiwanese NHIRD to probe the relative risk odds of AAU for AS development, and consisted of all patients diagnosed with AAU (n = 5621) (ICD-9-CM codes 364.00). The relative risks of AS between AAU patients and controls were compared by estimating the crude hazard ratio with logistic regression. Kaplan–Meier analysis was used to calculate the cumulative incidence rates of developing AS, and a log-rank test was used to analyze the differences between the survival curves. Separate Cox proportional hazard regressions were performed to compute the AS-free rate after adjusting for possible confounding factors such as age and sex. Results: The crude hazard ratio was 2.667 for the AAU group, and the adjusted hazard ratio was 2.705 for the AAU group. The observation time of the AS-free group was shorter for AAU patients compared with the control group (1507 versus 1578 days). Moreover, in the AAU patients, the younger age onset of AAU (less than 30 years old here) would lead to an earlier diagnosis of AS later with a median of 1445.5 (742–2241) versus 1544 (819–2289) days of survival for the group of age onset of AAU greater than 30 years old. The difference is statistically significant (p < 0.05). Conclusions: AAU was a risk factor for AS. To identify AAU as an extra-articular manifestation is crucial for early diagnosis and treatment of AS and containing functional loss accordingly. PMID:28124984

    We investigated the vision-related quality of life (VR-QOL) in patients with HLA-B27 associated anterior uveitis (AU). The study was conducted in 2012 at the ophthalmology department of the University Medical Center of Groningen. We included AU patients who were HLA-B27 positive and/or were diagnosed by a rheumatologist with an HLA-B27 associated systemic disease. Sixty-one of 123 (50%) adult patients participated. All patients filled-out the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25), Beck Depression Inventory (BDI-II), social support lists and an additional questionnaire for gathering general information. Medical records were reviewed for clinical characteristics. Analyses were conducted on various patient and ocular characteristics. We compared our NEI VFQ-25 scores with those previously found in the literature. Our main outcome measures were VR-QOL scores and their associations with various general patient and ocular characteristics. We found that the NEI VFQ-25 mean overall composite score was 88.9±8.8, which is relatively high, but lower than that found in a normal working population. The mean general health score was 47.4±20.8, which is lower than in patients with other ocular diseases. Patients with a systemic disease scored significantly lower on general health and VR-QOL, compared to patients without a systemic disease. Patients with a depression (6/59 (10%)) frequently had ankylosing spondylitis (5/6 patients) and they scored significantly worse on VR-QOL. We concluded that patients with HLA-B27 associated AU have a relatively high VR-QOL. However, the presence of a systemic disease is associated with lower VR-QOL and general health scores. In addition, depression is associated with a lower VR-QOL. PMID:26808922

    To analyze the effectiveness of immunosuppressants and biological therapies in autoimmune posterior uveitis, chronic anterior uveitis associated with juvenile idiopathic arthritis, and macular edema. Systematic review. We conducted a sensitive literature search in Medline (from 1961) and EMBASE (from 1980) until October 2007. Selection criteria were as follows: (1) population: autoimmune posterior uveitis, chronic anterior uveitis in juvenile idiopathic arthritis, and macular edema; (2) intervention: immunosuppressive and biologic therapies; (3) outcomes: visual acuity, Tyndall, vitreous haze, macular edema, pars planitis, and retinal vasculitis. There were no limitations regarding study design. The quality of each study was evaluated using the Jadad's scale and Oxford Levels of Evidence. Two hundred sixty-five articles were selected for detailed review of the 4235 found in the initial search: 128 records were on immunosuppressants, 105 on biological therapies, and 32 on macular edema. Overall, both the immunosuppressive and the biologic therapies appeared effective in the treatment of autoimmune posterior uveitis, except for daclizumab in uveitis related to Behçet's disease, and for etanercept in any uveitis. In the treatment of macular edema, the drugs tested were also effective. Based on the evidence collated, immunosuppressants and biological therapies (except for daclizumab in Behçet and etanercept) may be effective in autoimmune uveitis and macular edema. No superiority may be inferred from this review. Copyright © 2011 Elsevier Inc. All rights reserved.

    We present a clinical case of chronic dissection of the anterior tibial artery leading to acute aneurysmal dilatation. Our patient, a 22-year-old man, had a history of trauma at the middle third of his left leg. Because of impending ischemia, he was diagnosed by emergency arteriography. We ligated the proximal and distal ends of the dissection and used a reversed saphenous vein for a short end-to-end bypass. Although the evolution of this dilatation had been silent, its clinical presentation was spectacular. The case is worthy of attention because of its extreme rarity, both as a dissection of a peripheral artery caused by trauma and as an aneurysmal dilatation at tibial level.

    To investigate the association of microRNA (miRNA) copy number variants (CNVs) with acute anterior uveitis (AAU) with or without ankylosing spondylitis (AS) and to assess underlying disease mechanisms. This study included 768 patients with AAU+AS+ or AAU+AS- and 660 controls from a Chinese Han population. Genotyping of CNVs was performed by TaqMan PCR. The expression of miRNAs, transfection efficiency of miR-9-3, and cytokine production were measured by real-time PCR, flow cytometry, or ELISA. The frequency of low copy numbers of miR-143, miR-146a, miR-9-3, and miR-205 and of high copy numbers of miR-301a and miR-23a was increased in patients with AAU+AS+ (P = 3.725 × 10-5 to 8.033 × 10-9). Additionally, the frequency of a low copy number of miR-146a and a high copy number of miR-23a and miR-205 was significantly increased in AAU+AS- patients (P = 0.002-0.001). The frequency of low copy number of miR-205 was increased in AAU+AS+ compared with AAU+AS- (P = 0.001). The mRNA expression of miR-9-3 was significantly decreased in patients with AAU+AS+ compared with controls and positively associated with its copy number. Additionally, the production of IL-1β and IL-6 was shown to be regulated by miR-9-3 in human primary retinal pigment epithelial cells. Low gene copy numbers of miR-143, miR-146a, miR-9-3, miR-205 and high gene copy numbers of miR-301a and miR-23a were associated with susceptibility to AAU+AS+. A low copy number of miR-146a and a high copy number of miR-23a and miR-205 were associated with AAU+AS-.

    To investigate the genes and signalling pathways located upstream of the inflammatory processes in human leukocyte antigen (HLA)-B27-associated acute anterior uveitis by gene expression microarray. Experimental study. HLA-B27-positive and-negative monocytes isolated from human peripheral blood were stimulated with Vibrio cholera lipopolysaccharide (LPS). Gene expression microarrays were used to identify the differentially expressed genes. Differentially expressed (DE) genes were testified by real-time PCR and analyzed by a series of bioinformatics-based techniques such as Gene Ontology, Kyoto Encyclopedia of Genes and Genomes. Gene expression microarray analysis revealed marked differences between HLA-B27-positive acute anterior uveitis (AAU) and HLA-B27-negative healthy control peripheral monocytes in the genes that were upregulated in response to LPS stimulation with 1105 genes and 25 genes respectively. Gene Ontology enrichment and pathway analysis indicated that genes participating in protein transport and folding were essential to the inflammatory process. The LPS receptor-Toll-like receptor (TLR)4 induced TLR signalling pathway and pathway related to Vibrio cholerae infection were located upstream of the network and contribute to the overall response. Among the DE genes, PIK3CA, PIK3CB, AKT3, and MAPK1 might play critical roles in inflammation. Equivalent LPS stimulation induces a different response in HLA-B27-positive peripheral monocytes compared to normal control, suggesting that the TLR pathway is involved in the pathogenesis of HLA-B27-associated AAU.

    Pediatric uveitis may be a serious health problem because of the lifetime burden of vision loss due to severe complications if the problem is not adequately treated. Juvenile idiopathic arthritis (JIA)-associated uveitis is characterized by insidious onset and potentially blinding chronic anterior uveitis. Periodic ophthalmologic screening is of utmost importance for early diagnosis of uveitis. Early diagnosis and proper immunomodulatory treatment are essential for good visual prognosis. The goal of treatment is to achieve enduring drug-free remission. The choice of therapeutic regimen needs to be tailored to each individual case. One must keep in mind that patients under immunomodulatory treatment should be monitored closely due to possible side effects. Local and systemic corticosteroids have long been the mainstay of therapy; however, long-term corticosteroid therapy should be avoided due to serious side effects. Steroid-sparing agents in the treatment of JIA-associated uveitis include antimetabolites and biologic agents in refractory cases. Among the various immunomodulatory agents, methotrexate is generally the first choice, as it has a well-established safety and efficacy profile in pediatric cases and does not appear to increase the risk of cancer. Other classic immunomodulators that may also be used in combination with methotrexate include azathioprine, mycophenolate mofetil, and cyclosporin A. Biologic agents, primarily tumor necrosis factor alpha inhibitors including infliximab or adalimumab, should be considered in cases of treatment failure with classic immunomodulatory agents.

    Childhood uveitis is a rare but serious disease that may causes visual loss. Causes are various and an underlying disease is not always found. To analyse clinical features and prognosis of uveitis in children. A retrospective, descriptive study of cases observed in a general pediatric unit over a period of 15 years (1990-2005) at Tunis. We gathered 18 cases of uveitis (girls 55.6% ,boys 44.4%). Mean age at the diagnosis was 8+/-3 years. Diagnosis was made after a decreased of visual acuity in 55.6% of cases. Localization of uveitis was anterior (6 cases), intermediate (1 case), posterior (3 cases) and total (8 cases). An underlying disease was found in only 5 patients: Behçet's disease (3 patients), juvenile chronic arthritis (1 patient), possible dermatopolymyositis (1 patient). The evolution was favorable in 10 cases with local treatment, systemic corticotherapy and/or immunosuppressive agents. Complications occurred in 3 cases. Causes of uveitis in childhood remains most often undiagnosed Our study illustrates the pending risk of severe visual impairment and strict ophtalmology follow-up is mandatory.

In particular, this article reviews the literature on identification and treatment of acute retinal necrosis due to herpes simplex virus, varicella virus, and cytomegalovirus. While no agreed-upon treatment has been identified, the characteristics of Ebola virus panuveitis is also reviewed. In addition, forms of parasitic infection such as Toxoplasmosis and Toxocariasis are summarized, as well as spirochetal uveitis. Syphilitic retinitis is reviewed given its increase in prevalence over the last decade. The importance of early identification and treatment of infectious uveitis is emphasized. Early identification can be achieved with a combination of maintaining a high suspicion, recognizing certain clinical features, utilizing multi-modal imaging, and obtaining specimens for molecular diagnostic testing.

    AIM—To investigate the effect of additional oral vitamins C and E on acute anterior uveitis.
METHODS—A placebo controlled double masked study on the effect of vitamin C 500 mg in combination with vitamin E 100 mg twice daily in 145 patients with acute anterior uveitis. As a primary end point variable, laser cell/flare measurements were performed. Best corrected and stenopeic visual acuity (VA) testing and clinical variable scores were measured.
RESULTS—Laser flare measurements (ph/s) before treatment were 207.1 (SD 258) in the vitamin group and 143.6 (156) in the placebo group. After 3 days corresponding values were 80.2 (129) and 54.7 (82), after 7 days 89.2 (187) (12.5) and 85.8 (208), after 14 days 47.1 (109.5) and 40.5 (116) after 28 days 23.1 (53.6) and 23.1 (48), and after 56 days 15.6 (26) and 15.3 (17). There was no significant difference in time trend between the two treatment groups (RMANOVA; p = 0.53). Baseline VA (logMAR) was 0.106 (0.241) in the vitamin group and 0.128 (0.456) in the placebo group. VA after 3 days was 0.236 (0.293) and 0.344 ( 0.489), after 7 days 0.204 (0.292) and 0.292 (0.479), after 14 days 0.162 (0.274) and 0.193 (0.454), after 28 days 0.096 (0.232) and 0.158 (0.436), and 0.026 (0.213) and 0.106 (0.437) after 56 days. Although no significant difference in time trend was detected, evaluation of the VA data of the last time point (56 days) by means of the Mann-Whitney test showed a significantly better VA in the vitamin group (p = 0.01).
CONCLUSIONS—There was no significant effect of vitamins C and E on laser flare measurements. The significant effect of the oral vitamins on visual acuity at 8 weeks after start of the oral vitamins C and E may indicate a protective effect in patients with acute anterior uveitis.

    The multiplicity of causes of uveitis makes diagnosis difficult. Determining epidemiological factors associated with uveitis allows better diagnostic orientation and facilitates therapeutic management. This is a retrospective study spanning four years from January 2012 to December 2015. We collected 105 cases with uveitis and studied its epidemiological, clinical and etiological aspects. The average age was 42 years, the most affected age group was 40-50 years. Men were more affected (57.14%) than women (42.86%). Uveitis was unilateral in 60.95% of cases. Anterior uveitis was found in 35.24%, intermediate uveitis in 5.71%, posterior uveitis in 10.48% and panuveitis in 48.57%. Etiologies were dominated by Behçet's disease, sarcoidosis and Vogt-Koyanagi-Harada disease. The origin remained unknown in 43.81% of cases. The evolution was variable. Uveitis is an intraocular inflammation which may represent a real threat to vision. The approach to discover its cause needs to be codified and based on several steps. Our results are relatively close to those found in the literature. Uveitis is a clinical entity where ophthalmology and internal medicine meet. The field of its causes and investigations for the diagnosis is extensive or even unlimited. This study highlighted the clinical challenges and emphasized the limitations of our clinical training in the management of uveitis.

    Objective Endogenous uveitis is a major cause of visual loss mediated by the immune system. The protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene encodes a lymphoid-specific phosphatase that plays a key role in T-cell receptor (TCR) signaling. Two independent functional missense single nucleotide polymorphisms (SNPs) located within the PTPN22 gene (R263Q and R620W) have been associated with different autoimmune disorders. We aimed to analyze for the first time the influence of these PTPN22 genetic variants on endogenous non-anterior uveitis susceptibility. Methods We performed a case-control study of 217 patients with endogenous non-anterior uveitis and 718 healthy controls from a Spanish population. The PTPN22 polymorphisms (rs33996649 and rs2476601) were genotyped using TaqMan allelic discrimination assays. The allele, genotype, carriers, and allelic combination frequencies were compared between cases and controls with χ2 analysis or Fisher’s exact test. Results Our results showed no influence of the studied SNPs in the global susceptibility analysis (rs33996649: allelic P-value=0.92, odds ratio=0.97, 95% confidence interval=0.54–1.75; rs2476601: allelic P-value=0.86, odds ratio=1.04, 95% confidence interval=0.68–1.59). Similarly, the allelic combination analysis did not provide additional information. Conclusions Our results suggest that the studied polymorphisms of the PTPN22 gene do not play an important role in the pathophysiology of endogenous non-anterior uveitis. PMID:23559857

    The present article reviews the epidemiology, pathogenesis, clinical features, diagnosis, and treatment of ankylosing spondylitis and its association with ocular changes. The authors used the PubMed (MEDLINE), LILACS, and Ophthalmology Library databases. Ankylosing spondylitis is a chronic inflammatory disease that usually affects the axial skeleton and can progress to stiffness and progressive functional limitation. Ankylosing spondylitis usually begins around the second to third decade of life, preferentially in HLA-B27-positive white males. Its etiology and pathogenesis are not completely understood, and its diagnosis is difficult. Clinical control and treatment are frequently satisfactory. Acute anterior uveíte is the most common extra-articular manifestation, occurring in 20%-30% of the patients with ankylosing spondylitis. Approximately half of the acute anterior uveíte cases are associated with the presence of the HLA-B27 antigen. It can be the first manifestation of an undiagnosed rheumatic disease, usually having a good prognosis and appropriate response to treatment. In conclusion, for better assessment and treatment of patients with uveitis, ophthalmologists and rheumatologists should work together.

    AIM To describe the results of vitrectomy and partial capsulectomy via anterior approach surgical technique in treatment of chronic postoperative endophthalmitis (CPE). METHODS Clinical records of 9 patients treated for CPE between 2006 and 2010 were reviewed retrospectively. All of these patients were treated with vitrectomy and partial capsulectomy via anterior approach. RESULTS Six of 9 patients were male. The average patients' age was (60±8.1) years. The average period between cataract extraction and onset of signs and symptoms was (3.6±1.3) weeks. The average presenting visual acuity was 0.3±0.1 and the average final post operative visual acuity was 0.7±0.2. The mean follow-up period was (28.1±8.9) weeks. In all patients, the inflammation subsided after surgery. CONCLUSION Our results suggest that anterior vitrectomy and partial capsulectomy via anterior approach may be considered as potentially useful and relatively less invasive technique to treat CPE.

    The aim of to test efficacy and safety of Echinacea purpurea (echinacea) extract in the control of low-grade uveitis. Fifty-one (51) patients with low-grade, steroid dependent, autoimmune uveitis were recruited; posterior uveitis was excluded. The start therapy was represented by topical desamethazone for anterior uveitis and oral prednisone, rapidly tapered, for anterior uveitis with inflammatory scores equal to +2 and in all cases of intermediate uveitis. Best-corrected visual acuity (BCVA) decrease or improvement was defined as a reduction or increase of 2 or more letters seen from the initial BCVA; ETDRS chart was used. Thirty-two (32) patients (21 with anterior uveitis and 11 with intermediate uveitis) received Echinacea (150 mg twice/day) as add-on therapy, whereas 20 patients (10 with anterior uveitis and 9 with intermediate uveitis) were treated with the conventional steroid therapy alone. Thirty-one (31) patients showed anterior uveitis and 20 intermediate uveitis. The follow-up duration was 9 months. At the last follow-up, 19/21 patients with anterior uveitis and 9/11 with intermediate uveitis treated with echinacea presented uveitis settled, with a steroid-off time of 209 and 146 days, respectively. BCVA was stable or improved in 19/21 of anterior uveitis and 9/11 of intermediate uveitis. No adverse reactions supposed to be resulting from commercial-grade echinacea were recorded. Patients who did not receive echinacea required a longer treatment period with steroids with a steroid-off time of 121 and 87 days. Systemic echinacea appears safe and effective in the control of low-grade autoimmune idiopathic uveitis.

    Chronic ruptures of the tibialis anterior tendon are often associated with tendon retraction and poor-quality tissue, resulting in large segmental defects that make end-to-end repair impossible. Interpositional allograft reconstruction has previously been described as an operative option in these cases; however, there are no reports of the clinical outcomes of this technique in the literature. Eleven patients with chronic tibialis anterior tendon ruptures underwent intercalary allograft recon-struction between 2006 and 2013. Patient demographics, injury presentation, and details of surgery were reviewed. Postoperative outcomes at a mean follow-up of 43.8 (range, 6-105) months included the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot score, Short Form-12 (SF-12) physical health score, Lower Extremity Functional Score (LEFS), visual analog scale (VAS) pain rating, dorsiflexion strength, gait analysis, and complications. The average postoperative dorsiflexion strength, as categorized by the Medical Council grading scale, was 4.8 ± 0.45. The average postoperative VAS score was 0.8 ± 1.1. The average LEFS was 66.9 ± 17.2, SF-12 physical health score was 40.1 ± 14.4, and AOFAS score was 84.3 ± 7.7. One complication occurred, consisting of transient neuritic pain in the superficial peroneal nerve distribution. There were no postoperative infections, tendon reruptures, reoperations, or allograft-associated complications. Allograft reconstruction of chronic irreparable tibialis anterior tendon ruptures yielded satisfactory strength, pain, and patient-reported functional outcomes. This technique offers a safe and reliable alternative, without the donor site morbidity associated with tendon transfer or autograft harvest.

    Four patients that had received an anterior cingulotomy (ACING) and five patients that had received both an ACING and an anterior capsulotomy (ACAPS) as an intervention for chronic, treatment refractory depression were presented with a series of dynamic emotional stimuli and invited to identify the emotion portrayed. Their performance was compared with that of a group of non-surgically treated patients with major depression (n=17) and with a group of matched, never-depressed controls (n=22). At the time of testing, four of the nine neurosurgery patients had recovered from their depressive episode, whereas five remained depressed. Analysis of emotion recognition accuracy revealed no significant differences between depressed and non-depressed neurosurgically treated patients. Similarly, no significant differences were observed between the patients treated with ACING alone and those treated with both ACING and ACAPS. Comparison of the emotion recognition accuracy of the neurosurgically treated patients and the depressed and healthy control groups revealed that the surgically treated patients exhibited a general impairment in their recognition accuracy compared to healthy controls. Regression analysis revealed that participants' emotion recognition accuracy was predicted by the number of errors they made on the Stroop colour-naming task. It is plausible that the observed deficit in emotion recognition accuracy was a consequence of impaired attentional control, which may have been a result of the surgical lesions to the anterior cingulate cortex.

    Equine recurrent uveitis (ERU) is the most frequently encountered cause of eye problems and blindness in horses. Classic treatment of ERU includes mydriatics, corticosteroids and nonsteroidal anti-inflammatory drugs. Despite vigorous topical and systemic treatment, however, in many cases, the prognosis for preserving vision remains poor. Experiences with surgical treatment of chronic endogenous uveitis in human patients have shown that vision-impairing axial opacities in the vitreous body can be removed by pars plana vitrectomy, and that a considerable decrease in the frequency and severity of uveitic relapses results. So far, 11 eyes of 10 horses were subjected to vitrectomy. All horses had suffered from 3 or more uveitic attacks and had a hazy vitreous. In all cases, at discharge from the clinic, the vitreous chamber was less hazy compared to preoperative findings. At follow-up examinations, 8 eyes (8/10) had normal i.o. pressure, and 2 (2/10) had subnormal i.o. pressure and the vitreous chambers were clear or contained only small floaters. Uveitic attacks had not been observed in the operated eyes. Postoperative complications included fibrinous, or fibrinous-haemorrhagic exudate in the anterior chamber of all eyes, and in one eye, a minor haemorrhage in the vitreous chamber. Our preliminary results indicate that pars plana vitrectomy assuring proper case selection and accurate surgical technique, may contribute to improvement of vision and may delay the progression of uveitic complications in horses.

    The treatment of noninfectious uveitis continues to remain a challenge for many ophthalmologists. Historically, clinical trials in uveitis have been sparse, and thus, most treatment decisions have largely been based on clinical experience and consensus guidelines. The current treatment paradigm favors initiation then tapering of corticosteroids with addition of steroid-sparing immunosuppressive agents for persistence or recurrence of disease. Unfortunately, in spite of a multitude of highly unfavorable systemic effects, corticosteroids are still regarded as the mainstay of treatment for many patients with chronic and refractory noninfectious uveitis. However, with the success of other conventional and biologic immunomodulatory agents in treating systemic inflammatory and autoimmune conditions, interest in targeted treatment strategies for uveitis has been renewed. Multiple clinical trials on steroid-sparing immunosuppressive agents, biologic agents, intraocular corticosteroid implants, and topical ophthalmic solutions have already been completed, and many more are ongoing. This review discusses the results and implications of these clinical trials investigating both alternative and novel treatment options for noninfectious uveitis. PMID:26035763

    Fuchs uveitis syndrome (FUS) is typically a unilateral, chronic, low-grade inflammation of the anterior segment which manifests in young adulthood. It is underdiagnosed because of its variable clinical spectrum. Although it can mimic various forms of anterior uveitis, it is important to make the correct diagnosis, based on clinical grounds, because both the management and prognosis differ from those of other uveitides. While its etiology remains unknown, it is possible that the disease has multiple causes that lead through different pathogenic mechanisms to the same clinical entity. Although many patients do not require treatment, it is not a benign condition, as often perceived. The high incidence of glaucoma makes it mandatory that all patients with FUS should be screened at regular intervals, even if they are not being actively treated and are relatively asymptomatic.

    Fuchs heterochromic uveitis (FHU) in its classic presentation is a unilateral, chronic, low grade, often asymptomatic anterior uveitis. It is characterized by a classic triad of iris heterochromia, cataract and keratic precipitates. Neovascularization of the iris and the anterior chamber (AC) angle (radial and circumferential) occurs in 6–22% of cases. This angle and iris new vessels can sometimes lead to a characteristic filiform haemorrhage and formation of hyphaema after AC paracentesis and is a hallmark of FHU known as Amsler–Verrey sign. This haemorrhage has been previously associated with trivial trauma, mydriasis, applanation tonometry, gonioscopy, or it may occur spontaneously. In the setting of cataract surgery it has been previously reported with the use of a Honan balloon. We report a case of cataract and FHU where the Amsler–Verrey sign developed intraoperatively during a phacoemulsification procedure. To the best of our knowledge, this is the first documented report of this sign occurring intraoperatively during cataract surgery. PMID:22767537

    Subretinal fibrosis and uveitis syndrome is a rare, potentially devastating, posterior uveitis of unknown aetiology, characterised bilaterally by initial multifocal choroiditis with later progressive subretinal fibrosis. We report a rare case of unilateral subretinal fibrosis and uveitis syndrome. To date, there are only two case reports of unilateral disease. Our patient presented with unilateral blur and was found to have reduced visual acuity. A Bartonella profile was positive and a diagnosis of Bartonella posterior uveitis was made. Several positive ocular findings in the anterior chamber and on fundoscopy consistent with the syndrome were found. When steroid therapy alone could no longer control active inflammation, the immunosuppressive agent mycophenolate was added. Over time subretinal fibrosis became established sparing the macula and associated complications occurred, but with mycophenolate, at four years, our patient's visual acuity had improved and remains stable. Moreover, four years after her initial presentation, her condition remains strictly unilateral.

    Tubulointerstitial nephritis and uveitis (TINU) is an important yet underrecognized ocular inflammatory syndrome. This review summarizes key historical publications that identified and defined the syndrome, and more recent literature that reveal the importance of urinary β2-microglobulin testing and kidney biopsy in the diagnostic evaluation of patients with TINU. Additionally, research studies providing new insights into disease pathogenesis are highlighted. In contrast with initial reports of TINU manifesting exclusively as an anterior uveitis in pediatric patients, more recent reports have identified TINU in patients of all ages with a wide range of ocular manifestations. Urinary β2-microglobulin has emerged as a sensitive and specific laboratory screening test, and the role of kidney biopsy in differentiating TINU from sarcoidosis continues to evolve. Genetic studies have identified HLA-DQA101, HLA-DQB105, and HLA-DRB101 as high-risk alleles and the identification of antimonomeric C-reactive protein antibodies suggests a role for humoral immunity in disease pathogenesis. Management strategies have evolved to include systemic anti-inflammatory treatment as a result of important outcome studies in patients with significant renal and ocular disease. With greater recognition, understanding, and treatment of this syndrome, both ocular inflammation and renal disease can be better addressed.

She complained of floaters and progressive blurring of vision in both eyes for some months, as well as arthralgia and cough. Her visual acuity was 0.3 in the right eye and 0.4 in the left eye. Biomicroscopy showed bilateral anterior granulomatous uveitis (1+ cells). Funduscopy showed bilateral vitritis 3+, snow banking and peripheral phlebitis. Fluorescein angiography did not show central vasculitis, and optical coherence tomography showed bilateral cystoid macular oedema. Fundus autofluorescence was normal. How would you initially assess this patient in order to decide which systemic examination should be performed, bearing in mind the ophthalmological manifestations?

    Background: Recent studies document alterations in cortical and subcortical volumes in patients with chronic primary insomnia (PI) in comparison with normal sleepers. We sought to confirm this observation in two previously studied PI cohorts. Methods: Two separate and independent groups of unmedicated patients who met Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition (DSM-IV) criteria for PI were compared with two separate, healthy control groups (Study 1: PI = 20, controls = 15; Study 2: PI = 21, controls = 20). Both studies included 2 weeks of sleep diaries supplemented by wrist actigraphy. The 3.0 T MRI-derived rostral anterior cingulate cortex (rACC) volumes were measured with FreeSurfer image analysis suite (version 5.0) and results normalized to total intracranial volume (ICV). Unpaired t-tests (two-tailed) were used to compare rACC volumes between groups. Post hoc correlations of rACC volumes to insomnia severity measures were performed (uncorrected for multiplicity). Results: Both studies demonstrated increases in normalized rACC volume in PI compared with control patients (Study 1: right side P = 0.05, left side P = 0.03; Study 2: right side P = 0.03, left side P = 0.02). In PI patients from Study 1, right rACC volume was correlated with sleep onset latency (SOL) by both diary (r = 0.51, P = 0.02) and actigraphy (r = 0.50, P = 0.03), and with sleep efficiency by actigraphy (r = -0.57, P = 0.01); left rACC volume was correlated with SOL by diary (r = 0.48, P = 0.04), and wake after sleep onset (WASO) (r = 0.49, P = 0.03) and sleep efficiency (r = -0.49, P = 0.03) by actigraphy. In Study 2, right rACC volume was correlated with SOL by diary (r = 0.44, P = 0.05) in PI patients. Conclusions: Rostral ACC volumes are larger in patients with PI compared with control patients. Clinical severity measures in PI correlate with rACC volumes. These data may reflect a compensatory brain response to chronic insomnia and may represent a marker of

    The purpose of this article is to study the clinical and demographic profile of uveitis-related ocular hypertension (OHT) and evaluate risk factors predisposing to development of OHT in uveitis. Two hundred patients (200 eyes) with uveitis were evaluated for type of uveitis and the presence of OHT [IOP > 21 mmHg]. All patients underwent a complete ophthalmic examination and appropriate systemic evaluation. Patients with OHT were started on appropriate antiglaucoma medication and were followed up for minimum of 6 months. Forty-two eyes (21 %) were found to have OHT. Anterior uveitis alone was seen in 22 (52.4 %), granulomatous uveitis was seen in 8 (19.1 %) eyes, while 13 eyes (30.9 %) had active uveitis. On multiple logistic regression, age greater than 60 years (p = 0.025), peripheral anterior synechiae (PAS) > 180° (p = 0.029), and steroid use (p < 0.001) were found to have significant association with OHT. Mean IOP at baseline was 24.6 ± 10.1 mmHg which decreased to 17.3 ± 4.5 mmHg at 6 months (p < 0.001). At 6 months, 30 eyes were medically controlled (71.4 %), 5 eyes underwent trabeculectomy with MMC (11.9 %), and in 7 eyes, antiglaucoma medication could be discontinued. One-fifth of eyes with uveitis had OHT. Risk factors for IOP elevation included increased age, PAS > 180°, and corticosteroid use.

Each dog was assigned to 1 of 4 treatment groups. Treatment groups were saline (0.9% NaCl) solution (1 mL, IV), meloxicam (0.2 mg/kg, IV), carprofen (4.4 mg/kg, IV), and flunixin meglumine (0.5 mg/kg, IV). Each dog was anesthetized, treatment was administered, and aqueocentesis was performed on each eye at 30 and 60 minutes after treatment. Aqueous humor samples were frozen at -80°C until assayed for PGE(2) concentration with an enzyme immunoassay kit. For all 4 treatment groups, PGE(2) concentration was significantly higher in samples obtained 60 minutes after treatment, compared with that in samples obtained 30 minutes after treatment, which indicated aqueocentesis-induced PGE(2) synthesis. For aqueous humor samples obtained 60 minutes after treatment, PGE(2) concentration did not differ significantly among groups treated with saline solution, meloxicam, and carprofen; however, the PGE(2) concentration for the group treated with flunixin meglumine was significantly lower than that for each of the other 3 treatment groups. Flunixin meglumine was more effective than meloxicam or carprofen for minimizing the PGE(2) concentration in the aqueous humor of dogs with experimentally induced uveitis. Flunixin meglumine may be an appropriate pre-medication for use prior to intraocular surgery in dogs.

    To summarize evidence regarding the effectiveness of anti-tumor necrosis factor α (anti-TNFα) treatments in childhood autoimmune chronic uveitis (ACU), refractory to previous disease-modifying antirheumatic drugs (DMARDs). A systematic search between January 2000 and October 2012 was conducted using EMBase, Ovid Medline, Evidence-Based Medicine (EBM) Reviews: American College of Physicians Journal Club, Cochrane libraries, and EBM Reviews. Studies investigating the efficacy of anti-TNFα therapy, in children ages ≤16 years, as the first treatment with a biologic agent for ACU, refractory to topical and/or systemic steroid therapy and at least 1 DMARD, were eligible for inclusion. The primary outcome measure was the improvement of intraocular inflammation, as defined by the Standardization of Uveitis Nomenclature Working Group criteria. We determined a combined estimate of the proportion of children responding to anti-TNFα treatment, including etanercept (ETA), infliximab (INF), or adalimumab (ADA). We initially identified 989 articles, of which 148 were potentially eligible. In total, 22 retrospective chart reviews and 1 randomized clinical trial were deemed eligible, thus including 229 children (ADA: n = 31, ETA: n = 54, and INF: n = 144). On pooled analysis of observational studies, the proportion of responding children was 87% (95% confidence interval [95% CI] 75-98%) for ADA, 72% (95% CI 64-79%) for INF, and 33% (95% CI 19-47%) for ETA. There was no difference in the proportion of responders between ADA and INF (χ(2) = 3.06, P = 0.08), although both showed superior efficacy compared with ETA (ADA versus ETA: χ(2) = 20.9, P < 0.001 and INF versus ETA: χ(2) = 20.9, P < 0.001). Although randomized controlled trials are needed, the available evidence suggests that INF and ADA provide proven similar benefits in the treatment of childhood ACU, and they are both superior to ETA.

    Uveitis is a common cause of vision loss, accounting for 10-15 % of all cases of blindness worldwide and affects individuals of all ages, genders, and races. Uveitis represents a broad range of intraocular inflammatory conditions due to complications of autoimmune diseases, bacterial infections, viral infections, and chemical and metabolic injuries. Endotoxin-induced uveitis (EIU) in rodents is an efficient experimental model to investigate the pathological mechanism and pharmacological efficacy of potential drug agents. EIU is characterized by clinically relevant classical signs of inflammation, including inflammatory exudates and cells in the anterior and vitreous chambers. EIU in small animal models such as rats, mice, and rabbits is a short-lived uveal inflammation that can be developed subsequent to administration of bacterial endotoxin, such as lipopolysaccharide. Here, we present a reproducible, reliable, and simplified protocol to induce EIU in mice. This method could be used with similar efficacy for EIU induction in other small animals as well.

    Equine recurrent uveitis (ERU) is a spontaneous disease characterised by repeated episodes of intraocular inflammation. The epidemiology of ERU has not been fully elucidated, but the condition appears to be much more common in horses than is recurrent uveitis in humans, especially in certain breeds and geographical regions. Both humans and horses show a similarly altered immune response and a marked autoimmune response as the primary disease pathophysiology. However, an inciting cause is not always clear. Potential inciting factors in horses include microbial agents such as Leptospira spp. Microbial factors and genetic predisposition to the disease may provide clues as to why the horse appears so susceptible to this disease. The aim of this review is to discuss the immunology and genetics of ERU, compare the disease in horses with autoimmune anterior uveitis in humans, and discuss potential reasons for the increased prevalence in the horse.

    Because of their varied spectrum of clinical presentation and difficulty in management, pediatric uveitis remains a challenge to the ophthalmologist. Variations in clinical presentation, difficulties in eye examination, extended burden of the inflammation over quality of life, limited treatment modalities, risk of amblyopia are the main challenges in the management of pediatric uveitis. Pediatric uveitis is a cause of significant ocular morbidity and severe vision loss is found in 25-33% of such cases. This article summarizes the common causes of uveitis in children with special approach to the evaluation and diagnosis of each clinical entity. PMID:24379547

    To describe the clinical pattern of uveitis in patients with retinitis pigmentosa (RP) at a tertiary care eye hospital over a period of 30 years. The medical records of 32 eyes of 22 patients of RP with uveitis were included in this study. Collected data included age, subsets of uveitis, best corrected visual acuities (BCVA), detailed laboratory investigations, and treatment. Mean age at presentation was 53.4 ± 18.8 years, and mean age of diagnosis of RP was 39.2 ± 21.4 years. Uveitis was bilateral in 10 (45.5%) patients. The most common of uveitis in current study was anterior uveitis (56.2%), followed by intermediate uveitis (43.8%). Cataract developed in 12 (37.5%) eyes, and three eyes had raised intraocular pressure. Ten patients (45.5%) required oral steroid, and one patient required oral methotrexate. Uveitis in RP patients is rare, but not uncommon. Coexistence of these disorders might support the inflammatory pathway in etiology of RP.

    To calculate the incidence rates of ocular complications and vision loss in HLA-B27-associated uveitis and to explore the effect of chronic inflammation on clinical outcomes. Retrospective longitudinal cohort study. The clinical records of 99 patients (148 uveitis-affected eyes) with HLA-B27-associated uveitis seen at a tertiary care center were included. The main outcome measures were ocular complications (posterior iris synechiae, band keratopathy, posterior subcapsular [PSC] cataracts, ocular hypertension, hypotony, cystoid macular edema, and epiretinal membrane) and vision loss. Anterior chamber inflammation was defined as ≥1+ grade inflammation. Chronic uveitis was defined as persistent inflammation with relapse in <3 months after discontinuing treatment or requiring medications to suppress inflammation for >3 months after reviewing the patient's entire clinical course. The clinical course was most commonly acute/recurrent (75%) or chronic (20%). The most common complications to develop during follow-up were ocular hypertension (0.10/eye-year) and PSC cataracts (0.09/eye-year). In multivariate analysis, the presence of posterior synechiae at presentation, inflammation, corticosteroid-sparing therapy, corticosteroid injections, chronic disease, and male gender were associated with a statistically significant increased risk of developing vision loss (20/50 or worse). Chronic disease course was associated with a 7-fold increased risk of visual impairment (hazard ratio [HR] = 6.8, P < .0001). The presence of inflammation during follow-up was associated with an increased risk of developing visual impairment (HR = 6.2, P < .0001). In multivariate analysis, chronic disease course and topical corticosteroids were associated with an increased risk of developing any incident ocular complication (HR = 2.2, P = .04 and HR = 3.3, P = .01, respectively). Poorly controlled inflammation was associated with the development of ocular complications including vision loss

    Uveitis is a heterogeneous group of clinical entities that have in common ocular inflammation. The wide range of causes of uveitis makes diagnosis and family support difficult; hence the pediatrician occupies a determinant site to provide a coherent and timely diagnostic strategy. The aim of this paper is to present a 16-year-old patient who consulted to the ophthalmologist for red eye associated with lacrimation, photophobia, and pain. Once the diagnosis of acute anterior uveitis was made, the specialist suggested a pediatrician consult to rule out a systemic disease.

    Purpose The purpose of this study was to compare the histologic features and cytokine profiles of experimental autoimmune uveitis (EAU) and a primed mycobacterial uveitis (PMU) model in rats. Methods In Lewis rats, EAU was induced by immunization with interphotoreceptor binding protein peptide, and PMU was induced by immunization with a killed mycobacterial extract followed by intravitreal injection of the same extract. Clinical course, histology, and the cytokine profiles of the aqueous and vitreous were compared using multiplex bead fluorescence immunoassays. Results Primed mycobacterial uveitis generates inflammation 2 days after intravitreal injection and resolves spontaneously 14 days later. CD68+ lymphocytes are the predominant infiltrating cells and are found in the anterior chamber, surrounding the ciliary body and in the vitreous. In contrast to EAU, no choroidal infiltration or retinal destruction is noted. At the day of peak inflammation, C-X-C motif ligand 10 (CXCL10), IL-1β, IL-18, and leptin were induced in the aqueous of both models. Interleukin-6 was induced 2-fold in the aqueous of PMU but not EAU. Cytokines elevated in the aqueous of EAU exclusively include regulated on activation, normal T cell expressed and secreted (RANTES), lipopolysaccharide-induced CXC chemokine (LIX), growth-related oncogene/keratinocyte chemokine (GRO/KC), VEGF, monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1α (MIP-1α), and IL-17A. In the vitreous, CXCL10, GRO/KC, RANTES, and MIP-1α were elevated in both models. Interleukin-17A and IL-18 were elevated exclusively in EAU. Conclusions Primed mycobacterial uveitis generates an acute anterior and intermediate uveitis without retinal involvement. Primed mycobacterial uveitis has a distinct proinflammatory cytokine profile compared with EAU, suggesting PMU is a good complementary model for study of immune-mediated uveitis. CXCL10, a proinflammatory cytokine, was increased in the aqueous and

    The loss of anterior teeth has serious functional, esthetic disabilities, in addition to compromising the patients' quality of life. Various etiologies can be attributed to the anterior tooth loss, including trauma, caries, and periodontal diseases. The chronic mouth breathing due to nasal adenoids is known to enhance the gingival and periodontal diseases. The dental literature proves the association of nasal breathing, tongue thrusting, and anterior open bite. Arch shape and tooth position are primarily determined by the equilibrium of the forces from tongue and perioral musculature. Increased force from tongue musculature in the tongue thrusting patient leads to flaring of anterior teeth, making them susceptible for periodontal and traumatic tooth loss. Replacement of the anterior teeth in this patient will also help in restoration of anterior guidance, which is critical for the health of temporomandibular joint, posterior teeth, and musculature.

    Uveitis is a common ophthalmic disorder that can be induced in hamsters by a single intravitreal injection of bacterial lipopolysaccharide (LPS). To examine the therapeutic effects of melatonin on uveitis, a pellet of melatonin was implanted subcutaneously 2 hours before the intravitreal injection of either vehicle or LPS. Both 24 hours and 8 days after the injection, inflammatory responses were evaluated in terms of i) the integrity of the blood-ocular barrier, ii) clinical signs, iii) histopathological studies, and iv) retinal function. Melatonin reduced the leakage of proteins and cells in the anterior segment of LPS-injected eyes, decreased clinical signs such as dilation of the iris and conjunctival vessels, and flare in the anterior chamber, and protected the ultrastructure of the blood-ocular barrier. A remarkable disorganization of rod outer segment membranous disks was observed in animals injected with LPS, whereas no morphological changes in photoreceptor outer segments were observed in animals treated with melatonin. Furthermore, melatonin prevented a decrease in LPS-induced electroretinographic activity. In addition, melatonin significantly abrogated the LPS-induced increase in retinal nitric-oxide synthase activity, tumor necrosis factor-α, and nuclear factor κB p50 and p65 subunit levels. These results indicate that melatonin prevents the clinical, biochemical, histological, ultrastructural, and functional consequences of experimental uveitis, likely through a nuclear factor κB-dependent mechanism, and support the use of melatonin as a new therapeutic strategy for the treatment of uveitis.

    To study patterns of uveitis in Indian children and compare with data sets published earlier in the literature. Consecutive patients below 16 years of age presenting to the uvea clinic of a tertiary eye care center were included prospectively through the period of July 2009-August 2013. Children with retinal vasculitis, exogenous endophthalmitis and masquerade syndromes were excluded from analysis. Uveitis was classified as per the nomenclature system adopted by the International Uveitis Study Group. Hemogram, Mantoux test and chest X-ray were done for each patient, along with tailored investigations and pediatric review as per clinical profile. Clinical pattern and etiology were the main outcome measures. One hundred and thirty-four children were analyzed. Anterior uveitis (40%) was the commonest pattern followed by intermediate uveitis (25%), panuveitis (18%) and posterior uveitis (17%). Bilateral disease was present in 54%, 15% had infectious uveitis, 10% had granulomatous uveitis and 54% had idiopathic uveitis. Complications were present in half of the patients. Juvenile idiopathic arthritis (22), followed by toxoplasmosis (10) and tuberculosis (5), was the commonest etiology. Intermediate uveitis, non-granulomatous inflammation and older onset of disease had the high odds ratio of having idiopathic disease. Patterns of pediatric uveitis can vary between regions from even within the same geopolitical region. Anterior uveitis is commonest, and juvenile idiopathic arthritis and toxoplasmosis are the most frequent etiologies. Diagnosis of pediatric ocular tuberculosis is more difficult than in adults and needs better and well-defined criteria.

    Autoimmune uveitis is an organ-specific disorder characterized by irreversible lesions to the eye that predominantly affect people in their most productive years and is among the leading causes of visual deficit and blindness. Currently available therapies are effective in the treatment of a wide spectrum of uveitis, but are often associated with severe side effects. Here, we review ongoing research with promising immunomodulatory therapeutic strategies, describing their specific features, interactions and the responses triggered by the targeted immune molecules that aim to minimize clinical complications and the likelihood of disease relapse. We first review the main features of the disease, diagnostic tools, and traditional forms of therapy, as well as the animal models predominantly used to understand the pathogenesis and test the novel intervention approaches aiming to control the acute immune and inflammatory responses and to dampen chronic responses. Both exploratory research and clinical trials have targeted either the blockade of effector pathways or of their companion co-stimulatory molecules. Examples of targets are T cell receptors (CD3), their co-stimulatory receptors (CD28, CTLA-4) and corresponding ligands (B7-1 and B7-2, also known as CD80 and CD86), and cytokines like IL-2 and their receptors. Here, we summarize the available evidence on effectiveness of these treatments in human and experimental uveitis and highlight a novel CD28 antagonist monovalent Fab′ antibody, FR104, which has shown preclinical efficacy suppressing effector T cells while enhancing regulatory T cell function and immune tolerance in a humanized graft-versus-host disease (GVHD) mice model and is currently being tested in a mouse autoimmune uveitis model with encouraging results.

This was a retrospective observational case series of 16 patients with CMV infection on qualitative polymerase chain reaction PCR-based assays for viral DNA in aqueous samples. Case records of 16 patients were reviewed and relevant clinical information was collected using a standardized data sheet. There were 10 male and 6 female patients, with 16 eyes included. The median age at the first attack was 52 years (range 27-77 years). Thirteen patients (81.3%) presented with an initial BCVA of 20/40 or better. Eleven eyes (68.8%) had anterior chamber inflammation of 1+ cells or less. Eight eyes (50.0%) had concomitant sectoral iris atrophy, while 2 eyes were noted to have heterochromic irides. Eleven patients (68.8%) presented with an elevated intraocular pressure. Seven patients (43.8%) had clinical features that led to a presumptive diagnosis of Posner-Schlossman syndrome, while 3 patients (18.8%) were initially diagnosed with Fuchs heterochromic iridocyclitis. Six patients were initially treated for uveitic glaucoma or anterior uveitis of unknown cause. There is a spectrum of clinical manifestations of CMV anterior uveitis. A high index of suspicion of a possible viral etiology, especially CMV, and subsequent accurate identification of the virus involved are fundamental to the overall therapeutic approach.

    Immune-mediated uveitis may be associated with a systemic disease or may be localized to the eye. T-cell-dependent immunological events are increasingly being regarded as extremely important in the pathogenesis of uveitis. Several studies have also shown that macrophages are major effectors of tissue damage in uveitis. Uveitis phenotypes can differ substantially, and most uveitis diseases are considered polygenic with complex inheritance patterns. This review attempts to present the current state of knowledge from in vitro and in vivo research on the role of genetics in the development and clinical course of uveitis. A review of the literature in the PubMed, MEDLINE, and Cochrane databases was conducted to identify clinical trials, comparative studies, case series, and case reports describing host genetic factors as well as immune imbalance which contribute to the development of uveitis. The search was limited to primary reports published in English with human subjects from 1990 to the present, yielding 3590 manuscripts. In addition, referenced articles from the initial searches were hand searched to identify additional relevant reports. After title and abstract selection, duplicate elimination, and manual search, 55 papers were selected for analysis and reviewed by the authors for inclusion in this review. Studies have demonstrated associations between various genetic factors and the development and clinical course of intraocular inflammatory conditions. Genes involved included genes expressing interleukins, chemokines, chemokine receptors, and tumor necrosis factor and genes involved in complement system. When considering the genetics of uveitis, common threads can be identified. Genome-wide scans and other genetic methods are becoming increasingly successful in identifying genetic loci and candidate genes in many inflammatory disorders that have a uveitic component. It will be important to test these findings as uveitis-specific genetic factors. Therefore, the

    Bilateral Fuchs uveitis associated with vitreous infiltration and posterior segment involvement requires a thorough diagnostic evaluation. The lack of well-defined diagnostic criteria makes identification of this entity difficult. The aim of this case report was to present the characteristics of a patient with atypical Fuchs uveitis and the procedures needed to rule out the differential diagnosis with specific attention to the utility of in vivo confocal microscopy (IVCM). Case Report One case of chronic bilateral uveitis with severe vitreous opacities is presented. After extensive systemic workup, including vitrectomy, the case had no identifiable systemic etiology. IVCM of the cornea revealed the presence of dendritiform keratic precipitates. Conclusion The diagnosis of Fuchs uveitis is based on clinical findings as no confirmatory laboratory tests are available. A high index of suspicion is key to an early diagnosis, especially in the cases with vitreous opacities and posterior segment manifestations. Auxiliary tests such as IVCM may aid the clinician in the diagnosis of Fuchs uveitis. PMID:26483668

    To evaluate the efficacy of golimumab on severe and frequent recurrent anterior uveitis in patients with HLA-B27-positive ankylosing spondylitis. In this study, 15 eyes of 12 HLA-B27-positive AS patients with resistant anterior uveitis who received 50 mg of subcutaneous golimumab (Gol) per month due to frequent uveitis recurrences were analyzed retrospectively between May 2013 and October 2015. Assessment criteria were uveitis activity, the number of recurrence of uveitis, visual acuity, systemic corticosteroid, or other drug requirement for maintenance of remission of AU. Twelve patients (15 eyes) with HLA-B27-positive ankylosing spondylitis and anterior uveitis have been treated with golimumab 50 mg/month. Remission of uveitis was observed in 12 eyes out of 15. Malign hypertension developed in one subject after the second dose of golimumab therefore the treatment was stopped and this subject was excluded from the study. Median follow-up time was 11 months (interquartile range: 8-18). No uveitic reaction was seen except in the patient who stopped treatment. No topical or systemic steroid necessity was needed except in two cases with oral 4 mg systemic maintenance. Visual acuity was significantly increased (p = 0.002). Golimumab may be a new and effective choice for maintaining remission and the prevention of recurrences of severe, resistant anterior uveitis in patients with HLA-B27-positive ankylosing spondylitis.

    This study aimed to investigate the incidence and prevalence of uveitis in Taiwan, and then analyzed the risk factors related to uveitis using multivariate regression. Population-based cohort study using medical claims data. We randomly selected 1 000 000 residents from the Taiwan National Health Insurance Research Database. All participants with correct registry data (96%) were included in the study. The study period was from 2000 to 2008. All types of uveitis were identified using the International Classification of Diseases, 9th revision, Clinical Modification diagnostic codes. The annual incidence and cumulative prevalence of uveitis were calculated. A univariate and a multivariate Poisson regression were used to determine the risk factors associated with uveitis. The first diagnosis of uveitis noted during the study period. The annual cumulative incidence rate of uveitis ranged from 102.2 to 122.0 cases per 100 000 persons over the study period, and the average incidence density was 111.3 cases per 100 000 person-years (95% confidence interval, 108.4-114.1). The cumulative prevalence was found to have increased from 318.8 cases per 100 000 persons in 2003 to 622.7 cases per 100 000 persons in 2008. Anterior uveitis was the most common location and accounted for 77.7% of all incident cases, which was followed by panuveitis, posterior uveitis, and intermediate uveitis. Multivariate regression analysis showed that males, the elderly, and individuals who lived in an urban area had higher incidence rates for uveitis. The epidemiology of uveitis in Taiwan differs from most previous studies in other countries. The incidence of uveitis in Taiwan has increased significantly recently. The elderly and individuals living in urban areas are the populations that are most commonly affected by uveitis. These findings are consistent with suggestions found in several recent studies.

    To study the value and safety of aqueous humor polymerase chain reaction (PCR) analysis for Herpes simplex, varicella zoster, cytomegalovirus, Epstein-Barr virus and Toxoplasma gondii in patients with uveitis. Records of 45 consecutive patients with anterior and posterior uveitis who underwent AC paracentesis with PCR were reviewed. The main outcome measure was frequency of PCR positivity. Secondary outcomes were alteration of treatment, safety of paracentesis, and correlation of keratitic precipitates with PCR positivity, RESULTS: The overall PCR positivity was 48.9 % (22/45). Therapy was changed because of the PCR results in 14/45 patients (37.7 %). One patient experienced a paracentesis related complication (1/45, 2.2 %) without long-term sequelae. Aqueous PCR altered the diagnosis and treatment in over a third of our patients and was relatively safe. Aqueous PCR should be considered for uveitis of atypical clinical appearance, recurrent severe uveitis of uncertain etiology, and therapy refractory cases.

    Autoimmune anterior uveitis (AU) accounts for at least half of the cases of noninfectious uveitis, and similarly to spondyloarthritis (SpA), its occurrence is related to HLA-B27 positivity. AU is significantly more frequently found in HLA-B27-positive subjects with SpA and is characterized by unilateral eye involvement, marked tendency to recur with involvement of both eyes in alternate fashion, and has good prognosis in the majority of cases. The estimated frequency of SpA in patients with AU is around 50%, whereas AU in SpA has been reported in at least 30% of cases. Across the SpA disease spectrum, AU has a frequency peak of 33.4% in patients with ankylosing spondylitis, while the estimated prevalence in psoriatic arthritis (PsA) and inflammatory bowel disease-associated SpA is 2%-25%, and 25%, respectively. In early PsA, the frequency of AU has been found in 9% of patients. The wide range of prevalence reported in PsA may be explained by the variable sets of classification criteria used for patient selection and the different length of followup. AU may precede the clinical features of SpA, may be present at diagnosis, or may complicate the SpA clinical course. However, the occurrence of AU in SpA as well as AU flares has been reduced through treatment of SpA with anti-tumor necrosis factor-α agents.

    To demonstrate the difficulties of the differential diagnosis between tuberculosis and sarcoidosis as the cause of posterior uveitis. A 56-year-old woman suffered from bilateral anterior uveitis, snow-ball like infiltrates in the vitreous, and peripheral retinochoroidal granulomas with marked exudation shown in fluorescein angiography. Angiotensin-converting enzyme, as a marker of sarcoidosis, was elevated; the tuberculin test, however, was negative. Chest X-ray revealed an infiltrate and numerous smaller granulomas. The presumptive diagnosis was sarcoidosis. Surprisingly, in the biopsy of the pulmonal lesion tubercle bacilli were detected by Ziehl-Neelsen staining. Thus, a diagnosis of pulmonal and also retinochoroidal tuberculosis was made. After tuberculostatic therapy the choroidal lesions healed off. In a second case, a 30-year-old man suffered from bilateral panuveitis with candle wax exudates near the retinal vessels. Chest X-ray revealed lymphomas in the hilus, and the lymph node biopsy showed granulomas with epitheloid cells, indicating sarcoidosis. Detection of mycobacterium tuberculosis by culture or histological criteria was negative. Only in the PCR was mycobacterium tuberculosis DNA detectable. Tuberculostatic therapy had no benefit. Under therapy with steroids, however, pulmonal and ophthalmologic findings rapidly disappeared. The difficult differential diagnosis between sarcoidosis and tuberculosis cannot always be made by laboratory tests or diagnostic imaging alone. Clinical manifestations, including response to therapy, are essential.

    The Tubulointerstitial Nephritis and Uveitis syndrome is a very rare condition, probably under-diagnosed in clinical practice. It is characterized by the combination of an interstitial nephritis and uveitis, and is an exclusion diagnosis. Tissue non caseating granuloma can be rarely present, with only 6 cases reported on bone marrow. We present a case of a 55 year old female with a 3-month history of asthenia and weight loss. Blood tests showed anemia and renal insufficiency. Renal biopsy revealed interstitial nephritis and the bone marrow biopsy showed caseating granuloma. One month later anterior uveitis of the left eye appeared. An extensive exclusion of all possible causes allowed a diagnosis of Tubulointerstitial Nephritis and Uveitis syndrome with caseating granuloma in bone marrow. As ocular and renal manifestations may not occur simultaneously, Tubulointerstitial Nephritis and Uveitis Syndrome should be systematically considered in cases of interstitial nephritis and/or uveitis, and tissue granulomas can be part of this rare syndrome.

    Purpose To describe the disease characteristics and visual outcome of pediatric uveitis. Design Retrospective longitudinal observation. Participants 527 pediatric uveitis patients from the National Eye Institute, University of Illinois, Chicago and Oregon Health Sciences University. Methods Retrospective chart review. Main outcome measures Demographics, uveitis disease characteristics, complications, treatments, and visual outcomes and were determined at baseline and at 1, 3, 5 and 10 year time points. Results The patient population was 54 % female; 62.4% White, 12.5% Black, 2.7% Asian, 2.1 % multiracial and 14.61% Hispanic. Median age at diagnosis was 9.4 years. The leading diagnoses were idiopathic uveitis (28.8%), juvenile idiopathic arthritis-associated uveitis (20.9%), and pars planitis (17.1%). Insidious onset (58%) and persistent duration (75.3%) were most common. Anterior uveitis was predominant (44.6%). Complications were frequent, and cystoid macular edema (Odds Ratio: OR 2.94, p=0.006) and hypotony (OR 4.54, p=0.026) had the most significant visual impact. Ocular surgery was performed in 18.9% of patients. The prevalence of legal blindness was 9.23% at baseline, 6.52% at 1 year, 3.17% at 3 years, 15.15% at 5 years and 7.69% at 10 years. Posterior uveitis and panuveitis had more severe vision loss. Hispanic ethnicity was associated with a higher prevalence of infectious uveitis and vision loss at baseline. Conclusions The rate and spectrum of vision threatening complications of pediatric uveitis are significant. Prospective studies using standard outcome measures and including diverse populations are needed to identify children most at risk. PMID:19651312

    Untreated chronic shoulder dislocation eventually leads to functional disability and pain. Open reduction with different fixation methods have been introduced for most chronic shoulder dislocation. We hypothesized that open reduction and simultaneous Bankart lesion repair in chronic anterior shoulder dislocation obviates the need for joint fixation and leads to better results than previously reported methods. Eight patients with chronic anterior dislocation of shoulder underwent open reduction and capsulolabral complex repair after an average delay of 10 weeks from injury. Early motion was allowed the day after surgery in the safe position and the clinical and radiographic results were analyzed at an average follow-up of one year. The average Rowe and Zarin's score was 86 points. Four out of eight shoulders were graded as excellent, three as good and one as fair (Rowe and Zarins system). All patients were able to perform their daily activities and they had either mild or no pain. Anterior active forward flexion loss averaged 18 degrees, external active rotation loss averaged 17.5 degrees and internal active rotation loss averaged 3 vertebral body levels. Mild degenerative joint changes were noted in one patient. The results show that the overall prognosis for this method of operation is more favorable than the previously reported methods and we recommend concomitant open reduction and capsulolabral complex repair for the treatment of old anterior shoulder dislocation.

    To describe the main characteristics of a cohort of patients with uveitis referred to a multidisciplinary unit in northern Spain. Retrospective analysis of clinical records of patients evaluated in the Multidisciplinary Unit of the Navarra Hospital Complex from the period January 2010 until March 2015. An analysis was performed on the demographic characteristics, origin, types of uveitis, laterality, and aetiology. The present series was also compared with 2 previous series from Castilla y León and Barcelona. A total of 500 patients were identified, with a mean age of 47.9±16.4 years, with 50% women. The most frequent type of uveitis was anterior uveitis (65.4%), followed by posterior uveitis (17.6%), panuveitis (15.2%), and intermediate uveitis (1.8%). The origin was unclassifiable in 31.2%, followed by non-infectious systemic disease in 29.2%. Ankylosing spondylitis was the most frequent cause in 10.8% of patients, followed by herpes infection in 9.2%, and toxoplasmosis in 7.8%, respectively. Compared with the 2other cohorts, the present cohort showed a higher proportion of unilateral anterior uveitis. Furthermore, the patients from the Navarra series had a higher prevalence of unilateral and idiopathic uveitis compared to the series from Barcelona. The main characteristics of the present cohort of patients with uveitis are similar to those of patients from other regions of our country. Unilateral anterior uveitis and idiopathic uveitis were the most frequent in our series. Copyright © 2016 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U.

    We describe the repair of a chronic bony Bankart lesion in a case with recurrent instability using standard techniques and equipment for addressing anteroinferior glenohumeral instability. A 25-year-old man with recurrent instability and a chronic bony Bankart lesion with a Hill-Sachs lesion was treated. The inferior 2 sutures and knotless anchors are placed through a low anterior portal, which improves the angle of approach to the inferior portion of the glenoid that is fractured. The knotless anchors are impacted through the low anterior portal, just superior to the level of the suture, as the fragment tends to retract medially and inferiorly, with the drill guide slightly on the face of the glenoid. The superior-anterior portal adjacent to the biceps tendon gives a better view of the glenoid articular cartilage position of the anchors required to restore the anatomic location of the fracture fragment. The low anterior portal improved and simplified the reduction of the fracture fragment to the glenoid neck by allowing access to the anterior-inferior bony Bankart lesion that was repairable with suture and knotless anchors using standardized techniques.

    Following an inconclusive study of differential lymphocyte counts in uveitis in which the peripheral blood was examined only once in the course of each case a longitudinal study has been carried out in patients with acute anterior uveitis. Venous blood lymphocytes were examined at intervals throughout the course of the illness, from presentation until six months later. No changes in E-rosetting T cells or total lymphocyte values have been found, nor any variations from normal in the helper (OKT4)/suppressor (OKT8) T-cell ratio. Random studies performed in a sample of patients with heterochromic cyclitis have also failed to reveal consistent abnormalities in peripheral blood lymphocyte parameters. PMID:6236843

    To assess the long-term outcomes and complications of patients with uveitis from juvenile idiopathic arthritis (JIA) treated with adalimumab. Prospective interventional case series. All patients who underwent treatment with adalimumab for JIA and anterior uveitis were prospectively included in the study. The anterior chamber inflammation was evaluated according to the Standardization of Uveitis Nomenclature criteria. Twenty-one patients (16 females, five males, 38 eyes) were included in the study. Mean age of patients at referral was 11.1 ± 3.8 (5-17) years. Before initiation of treatment, mean duration of arthritis was 7.0 ± 5.5 (median, 6) months, mean duration of uveitis was 7.0 ± 4.4 (median, 7) months. Oligoarticular arthritis was present in 15 cases (71 %), polyarticular arthritis in six cases (28 %). After a mean follow-up of 18.2 ± 7.7 (9-41) months, resolution of anterior chamber inflammation was obtained in 29/38 eyes (76 %). The anterior uveitis flare rate during the 12 months prior to enrollment was 1.6 ± 0.4/year, and was reduced during adalimumab treatment to 0.7 ± 0.3/year (p<0.001). A significant decrease of the number of relapses/month was present after onset of treatment with adalimumab (0.18 ± 0.2 before versus 0.02 ± 0.1 after treatment onset, p<0.001). No significant correlation was found between relapse number and age, sex, type of JIA and doses of previous steroid treatment (p>0.05). Adalimumab showed to be effective and relatively safe for treatment of JIA-associated uveitis.

    To evaluate the incidence of remission among patients with intermediate uveitis; to identify factors potentially predictive of remission. Retrospective cohort study. Involved eyes of patients with primary noninfectious intermediate uveitis at 4 academic ocular inflammation subspecialty practices, followed sufficiently long to meet the remission outcome definition, were studied retrospectively by standardized chart review data. Remission of intermediate uveitis was defined as a lack of inflammatory activity at ≥2 visits spanning ≥90 days in the absence of any corticosteroid or immunosuppressant medications. Factors potentially predictive of intermediate uveitis remission were evaluated using survival analysis. Among 849 eyes (of 510 patients) with intermediate uveitis followed over 1934 eye-years, the incidence of intermediate uveitis remission was 8.6/100 eye-years (95% confidence interval [CI], 7.4-10.1). Factors predictive of disease remission included prior pars plana vitrectomy (PPV) (hazard ratio [HR] [vs no PPV] = 2.39; 95% CI, 1.42-4.00), diagnosis of intermediate uveitis within the last year (HR [vs diagnosis >5 years ago] =3.82; 95% CI, 1.91-7.63), age ≥45 years (HR [vs age <45 years] = 1.79; 95% CI, 1.03-3.11), female sex (HR = 1.61; 95% CI, 1.04-2.49), and Hispanic race/ethnicity (HR [vs white race] = 2.81; 95% CI, 1.23-6.41). Presence/absence of a systemic inflammatory disease, laterality of uveitis, and smoking status were not associated with differential incidence. Our results suggest that intermediate uveitis is a chronic disease with an overall low rate of remission. Recently diagnosed patients and older, female, and Hispanic patients were more likely to remit. With regard to management, pars plana vitrectomy was associated with increased probability of remission. Copyright © 2016 Elsevier Inc. All rights reserved.

    Anterior tibial stress fractures are associated with high rates of delayed union and nonunion, which can be particularly devastating to a professional athlete who requires rapid return to competition. Current surgical treatment strategies include intramedullary nailing, which has satisfactory rates of fracture union but an associated risk of anterior knee pain. Anterior tension band plating is a biomechanically sound alternative treatment for these fractures. Tension band plating of chronic anterior tibial stress fractures leads to rapid healing and return to physical activity and avoids the anterior knee pain associated with intramedullary nailing. Case series; Level of evidence, 4. Between 2001 and 2013, there were 13 chronic anterior tibial stress fractures in 12 professional or collegiate athletes who underwent tension band plating after failing nonoperative management. Patient charts were retrospectively reviewed for demographics, injury history, and surgical details. Radiographs were used to assess time to osseous union. Follow-up notes and phone interviews were used to determine follow-up time, return to training time, and whether the patient was able to return to competition. Cases included 13 stress fractures in 12 patients (9 females, 3 males). Five patients were track-and-field athletes, 4 patients played basketball, 2 patients played volleyball, and 1 was a ballet dancer. Five patients were Division I collegiate athletes and 7 were professional or Olympic athletes. Average age at time of surgery was 23.6 years (range, 20-32 years). Osseous union occurred on average at 9.6 weeks (range, 5.3-16.9 weeks) after surgery. Patients returned to training on average at 11.1 weeks (range, 5.7-20 weeks). Ninety-two percent (12/13) eventually returned to preinjury competition levels. Thirty-eight percent (5/13) underwent removal of hardware for plate prominence. There was no incidence of infection or nonunion. Anterior tension band plating for chronic tibial stress

    The aim of this study was to report on the prevalence of uveitic secondary glaucoma (USG) and ocular hypertension in patients with uveitis in Thailand, and to identify factors associated with the development of USG and its visual outcome. This is a retrospective cohort study. We included 174 consecutive uveitis patients (237 affected eyes) visiting the Ophthalmology Department of Chiang Mai University Hospital, Thailand, from January 2013 to March 2013. The prevalence of USG was 29% (51/174) and that of ocular hypertension was 18% (32/174). The follow-up period ranged from 3 to 96 months (mean±SD=33±21 mo). Characteristics associated with the development of USG were as follows: age at onset of uveitis above 60 years and longer duration of uveitis (P=0.001). No association between location of uveitis and development of USG was observed. Clinical entities associated with the highest prevalence of USG consisted of Posner-Schlossman syndrome and herpetic uveitis. Within the anterior uveitis group, viral etiology was strongly associated with the development of USG, whereas human leukocyte antigen-B27 (HLA-B27)-associated anterior uveitis had lower prevalence of USG than did their HLA-B27-negative counterparts. The prevalence of patients with at least 1 blind eye was significantly higher in those who developed USG (21/51; 41%) than in uveitis patients without glaucoma (22/123; 18%, P=0.001). Characteristics associated with visual loss in USG included poor visual acuity at presentation (P<0.001), and undergoing glaucoma surgery (P<0.05). The prevalence of secondary glaucoma among Southeast Asian patients with uveitis was 29%. Blindness in at least 1 eye developed more commonly in patients with USG than in uveitis patients without USG.

    Purpose We report the clinical course and visual outcome of patients with diabetes mellitus (DM) who subsequently developed uveitis from any cause. Methods Longitudinal, retrospective case note review. Results A total of 36 patients (M/F: 18/18, 58 eyes) were included, Of the 36 patients, 35 had Type 2 DM and one had Type 1 DM. Mean age of onset of DM was 49 years and uveitis 55 years. The uveitis was bilateral in 22 (61%) patients. There were 19 patients with anterior uveitis, 12 with panuveitis and 5 with intermediate uveitis. Mean follow up was 4.4 years (range 1-18). Mean number of uveitis recurrences was 3 (range 1-7). Causes of vision of 6/18 or worse appeared related to the uveitis in 9 eyes and diabetes in 4 eyes. Cataract occurred in 22 eyes, glaucoma in 17 eyes, and cystoid macular oedema in 10 eyes. Diabetic retinopathy was detected in 38 (65.5%) eyes (29 non-proliferative including 6 with clinically significant macular oedema, and 9 proliferative). Progression of diabetic retinopathy to proliferative stage occurred in 7 eyes of 4 patients over a mean duration of 4.4 years. In 10 patients with active uveitis the mean HbA1c was 80 mmol/mol [9.5%], (range 49-137 [6.6-14.7]), and 67 mmol/mol [8.3%] (range 46-105 [6.4-11.8]) when the uveitis was quiescent, p = 0.01. Better glycaemic control was required in 10 patients during episodes of uveitis. Conclusions Patients with DM who develop uveitis may have a high complication rate, reduced vision and poor glycaemic control. Checking blood glucose during episodes of uveitis is important.

    [125I]Corticotropin-releasing factor binding was measured in membrane homogenates prepared from the anterior pituitary, frontal cortex, motor cortex, somatosensory cortex, mesolimbic area (olfactory tubercle and nucleus accumbens), caudate putamen, hypothalamus, midbrain, and cerebellum from control and chronically stressed rats. The stressor consisted of 3 or 14 days of around-the-clock intermittent foot-shock (approximately one trial per 5-min frequency) that could be avoided or escaped on 90% of the trials presented by pulling a ceiling chain. Plasma corticosterone levels were almost doubled in stressed rats following 3 days of chronic stress and remained significantly elevated in rats stressed for 14 days as compared to controls. Plasma corticotropin levels were similar in controls and stressed animals in both the 3- and 14-day experiments. [125I]Corticotropin-releasing factor binding was decreased in anterior pituitary and frontal cortex following 3 days of chronic stress; binding affinity of anterior pituitary membranes was not different between control and stressed animals. [125I]Corticotropin-releasing factor binding was similar in control and 3-day-stressed animals in the other brain areas examined. After 14 days of chronic stress, hypothalamic [125I]corticotropin-releasing factor binding was decreased in stressed rats as compared to control animals but no other differences were seen. The decrease in the apparent number of anterior pituitary corticotropin-releasing factor receptors following 3 days of stress may be due, in part, to increased plasma corticosterone levels and/or increased corticotropin-releasing factor secretion during that time.(ABSTRACT TRUNCATED AT 250 WORDS)

    Fuchs' uveitis is very often diagnosed with substantial delay, which is at the origin of deleterious effects such as unnecessary treatment and its consequences. The aim of this study was to analyse the type and frequency of posterior inflammatory and fluorescein angiographic signs in Fuchs' uveitis in conjunction with other clinical signs. Patients seen at the Centre for Ophthalmic Specialised Care (COS) in Lausanne and the Memorial A. de Rothschild, Clinique Générale-Beaulieu in Geneva between 1995 and 2008 with the diagnosis of Fuchs' uveitis and who had undergone a fundus fluorescein angiography (FFA) were analysed. In addition to FFA signs, the data collected included age, gender, initial and final visual acuities, clinical findings at presentation, mean diagnostic delay and ocular complications. Between 1995 and 2008, 105 patients seen in our centres in Lausanne and Geneva were diagnosed with Fuchs' uveitis. Forty of them (38.1%) had undergone at least one FFA. One patient was excluded because of a concomittant diagnosis of multiple sclerosis. In 28 of 39 patients (71.2%) diagnosis was not reached at presentation with a mean diagnosis delay of 3.67 ± 4.86 years (range: 1 month-24 years). The original erroneous diagnosis was intermediate uveitis in 16 patients (57.1%), posterior uveitis in two patients (7.1%), panuveitis in four patients (14.3%) and anterior granulomatous uveitis in six patients (21.4%). Fluorescein angiography demonstrated the presence of disc hyperfluorescence in 43/44 eyes (97.7%), sectorial peripheral retinal vascular leaking in 6/44 eyes (13.6%) and cystoid macular oedema in 4/44 eyes (9.1%), all of which were seen in eyes having undergone cataract surgery. Fuchs' uveitis was bilateral in 5/39 patients (12.8%). The most frequent clinical signs were vitritis in 42/44 eyes (95.5%), stellate keratic precipitates in 41 eyes (93.2%), posterior subcapsular opacities or cataract in 19 eyes (43.2%), and heterochromia in 19 eyes (43.2%).

    To evaluate the presence of fungi in patients with chronic anterior blepharitis with periodic acid-Schiff (PAS) staining of the eyelashes in addition to the conventional methods of fungal cultures and direct microscopy. Nineteen patients with chronic anterior blepharitis of seborrheic or mixed seborrheic/staphylococcal type and 11 healthy age- and sex-matched controls were included in this prospective, nonrandomized, cross-sectional study. Blepharitis was diagnosed based on clinical evidence of greasy scales between the cilia, lid margin erythema, conjunctival hyperemia, telangiectasia, thickening, or irregularity of the eyelid margins by slit-lamp biomicroscopy. Eyelash samples were obtained by epilation with a sterile forceps and evaluated with PAS staining, fungal cultures, and direct microscopy. We demonstrated fungal elements with PAS staining in 79% of the blepharitis group (hyphae and/or spores) and 18% of the control group. The difference was statistically significant (P=0.002). Four patients in the blepharitis group (21%) had positive cultures for fungi. The isolated fungi were Penicillium species (2 cases), Candida species (1 case), and Trichophyton verrucosum (1 case). Direct microscopic examination revealed Demodex mites in 42.1% of the blepharitis group. No culture growth or Demodex mites were observed in the control group. We have shown fungi with PAS staining in the majority of patients with chronic anterior blepharitis. Further controlled studies are necessary to clarify the role of fungi in the etiopathogenesis of blepharitis.

    Experimental uveitis is one of the main models in the diseases of autoimmunological background. The purpose of this paper was to analyze the quantitative histological changes in the experimental uveitis, induced by different types of homogenous endotoxin salts of Havnia alvei. We studied 74 eyes of Lewis rats (males) divided into 4 groups. Each group received a homogenous salt of Havnia alvei in a single subcutaneous injection. In the 1 group-LPS Ca++, in 2 group-LPS Na++, in 3 group-LPS 981, in 4 group physiological salt (control group). The histologic and immunocitochemical examinations were performed after 24, 48 hours, and after 4 and 7 days following the injection. The histologic changes were analyzed (he intensity of inflammatory reaction) using a Highly Optimazed Microscope Enviroment system. The most intensive inflammation was observed in experimental group after 24 hours (n the LPS 981D group in 5 rats out of 6, in LPS Ca++ group in 3 rats out of 6). After 48 hours the intensity of inflammatory reaction visibly decreased. On the fourth day the inflammation revealed a minimal intensity and after 7 days was practically absent. In the control group minimal inflammation was observed only in a few rats. Cilliary body hypermia was present for 48 hours in most of the experimental rats. Only a few of them had hyperemia on the fourth day. In the posterior segment minimal inflammation was noted at the end of the first day (I and II-nd group after 24 hours); this process continued until the fourth day, on the 7th day disappeared. The most intensive inflammation of the anterior and posterior choroidal segment is caused by homogenous salts of Havnia alvei 981.

    The purpose of this study is to review the results of treatment of juvenile idiopathic arthritis-related uveitis with the use of intravitreal dexamethasone implant. Sixteen eyes with Juvenile idiopathic arthritis (JIA)-associated uveitis received intravitreal dexamethasone implant to treat recalcitrant anterior segment inflammation (43.7 %), chronic macular edema (6.2 %), or a combination of both (50 %). One month after injection, mean visual acuity had improvement to 39.6 ± 11 ETDRS letters (p < 0.001). Mean AC cells measure at 1 month was 0.79 and 0.75 at 3 months. One month after injection, there was a significant reduction of central retinal thickness (CRT) to 342.4 ± 79.3 µm (p < 0.01). One month after the second implant, 11 eyes (91.6 %) achieved improved activity of the anterior uveitis, and mean best-corrected visual acuity improved to 44.6 ± 8.1 ETDRS letters (p < 0.01). At 1 month after the second injection, 4/5 eyes had resolution of macular edema with CRT of 250.4 ± 13.7 µm (p < 0.01). Of the 16 eyes, 12 eyes received a second injection at mean of 7.5 ± 3.1 months after the first treatment, and 5 eyes received a third Ozurdex injection on average 7 ± 4.6 months after the second injection. Of the 16 eyes, five eyes were pseudophakic prior to injection. Of the remaining 11 eyes, 8 (73 %) developed worsening posterior subcapsular cataract at a mean of 7.3 ± 1.2 months after the first injection. After the first injection, only one eye required topical antiglaucoma therapy with maximum pressure of 25 mmHg. In patients with recalcitrant JIA-associated active uveitis, injection of sustained-release dexamethasone can achieve control of anterior inflammation and resolution of macular edema.

    Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease, defined by the association of idiopathic acute TINU. The aim of our work was to determine the characteristics of adult TINU syndrome in France, and to assess factors (including treatment) influencing medium-term prognosis.We conducted a nationwide study including 20 French hospitals. Clinical, laboratory, and renal histopathologic data of 41 biopsy-proven TINU syndromes were retrospectively collected. The patients were diagnosed between January 1, 1999 and December 1, 2015.Twenty-five females and 16 males were included (F/M ratio: 1.6:1). The median age at disease onset was 46.8 years (range 16.8-77.4) with a median serum creatinine level at 207 μmol/L (range 100-1687) and a median estimated glomerular filtration rate (eGFR) at 27 mL/min per 1.73 m (range 2-73). Twenty-nine patients (71%) had a bilateral anterior uveitis and 24 (59%) had deterioration in general health at presentation. Moderate proteinuria was found in 32 patients (78%) (median proteinuria 0.52 g/24 h; range 0.10-2.10), aseptic leukocyturia in 25/36 patients (70%). The evaluation of renal biopsies revealed 41 patients (100%) with an acute tubulointerstitial nephritis, 19/39 patients (49%) with light to moderate fibrosis and 5 patients (12%) with an acute tubular necrosis. Thirty-six patients (88%) were treated with oral corticosteroids. After 1 year of follow-up, the median eGFR was 76 mL/min per 1.73 m (range 17-119) and 32% of the patients suffered from moderate to severe chronic kidney disease. Serum creatinine (P < 0.001, r = -0.54), serum bicarbonate and phosphate levels (respectively, P = 0.01, r = 0.53; and P = 0.04, r = 0.46), and age (P = 0.03, r = -0.37) at the 1st symptoms were associated with eGFR after 1 year. During the 1st year 40% of patients had uveitis relapses. The use of oral corticosteroids was not associated with a better kidney function but was associated with fewer uveitis relapses

    Authors compared clinical and economic effeciency of treatment of the classical corticosteroids therapy and modern immunosuppressive treatment or their combination. Retrospective evaluation carried out in 2012, covering 2006-2011, monitored sample of 27 patients, 16 women and 11 men, 45 eyes with disabilities. The average age in the last year of follow-up monitoring was 30.2, ranging from 14 to 76 years. The mean duration of disease for the whole sample is 16.5 years with a range from 6 to 36 years. Three basic diagnoses were included in investigated group: chronic iridocyclitis in 59 % of eyes, intermediate uveitis in 30 % of eyes and sympathetic ophthalmia in 11 % of eyes. The optimal treatment not be determined, however, combined corticosteroid sparing therapy was the most beneficial to maintain in terms of visual acuity with minimal side effects and cost effectiveness. Successful outcomes of treatment were observed for intermediate uveitis, because the visual acuity improved in nine letetters of ETDRS chart in the study. Satisfactory treatment was proved in chronic iridocyclitis and sympathetic ophthalmia in general, because visual acuity improved in a few letters of ETDRS chart, in the same line as in the beginning of the six-year follow-up. Rounded average annual prize for treatment including pharmacotherapy, outpatient and inpatient care and laboratory follow-up was in chronic iridocyclitis € 990, in intermediate uveitis € 310 and sympathetic ophthalmia € 1550. Pharmacotherapy exceeded the financial appraisal of specialized medical and inpatient care in total cost. Key words: uveitis, corticosteorids, immunosuppression, costeffectivness.

    Equine recurrent uveitis (ERU) is an autoimmune disease that occurs with a high prevalence (10%) in horses. ERU represents the only reliable spontaneous model for human autoimmune uveitis. We already identified and characterized novel autoantigens (malate dehydrogenase, recoverin, CRALBP) by analyzing the autoantibody-binding pattern of horses affected by spontaneous recurrent uveitis (ERU) to the retinal proteome. CRALBP also seems to be relevant to human autoimmune uveitis. Proteomic screening of vitreous and retinal samples from ERU diseased cases in comparison to healthy controls has led to the identification of a series of differentially regulated proteins, which are functionally linked to the immune system and the maintenance of the blood-retinal barrier.

    The pathogenic mechanism of equine recurrent uveitis (ERU) is still poorly defined and many variations between experimental animal models and spontaneous disease exist. The aim of our study was to investigate if Th17 cell-mediated response plays role in the pathogenesis of the used experimental model in horses and to reveal its pathological findings. Experimental uveitis was induced in 6 healthy horses. The concentrations of retinal autoantigen CRALBP and IL-17 were measured using ELISA in aqueous humor and vitreous body of the 12 inflamed eyes as well as in 12 control non-inflamed eyes taken from 6 horses in slaughter house. After centrifugation of the two eye media, smears were prepared and cytological investigation was performed. Tissue specimens were taken from all eye globes and were submitted to histopathological investigation. CRALBP and IL-17 concentrations were significantly elevated in eye media of horses with experimental uveitis in comparison with controls. Cytological and histopathological findings corresponded to the changes characteristic of chronic immune-mediated inflammation with mononuclear cell infiltration of uvea, choroid, retina, and eye media as well as severe retinal destruction. Our study demonstrated the involvement of the retinal autoantigen CRALBP as well as IL-17 in the pathogenesis of experimental uveitis in horses. These findings suggests that this experimental uveitis in horses may serve as a suitable animal model for investigation of IL-17- mediated immune response during spontaneous autoimmune uveitis in horses as well as in humans.

    Sleep-waking profiles were obtained from 130 7 hr stimulation-EEG recording sessions in a series of cats bearing chronically implanted stimulating electrodes in the regions of the area postrema and anterior raphe nuclei. The results indicated that: (a) during electrical stimulation of the region of the area postrema with 0.5 or 10 Hz at 1 and 2 mA there were significant increases in the occurrence of the deeper aspects of slow-wave sleep and in REM sleep. These elevations were significant in comparison to nonstimulation baselines and to sleep profiles obtained during stimulation of points located dorsal and anterior to the area postrema. (b) Stimulation of the medial reticular formation including the anterior raphe using the same parameters employed for the area postrema did not alter the occurrence of any stage of sleep. These findings indicate that the region of the area postrema may be more involved in the generation of sleep than the anterior raphe nuclei.

    20/60 or better in 60 (90.9%) patients in Phaco group and 53 (88.3%) in the manual SICS group (P=0.478). The mean surgical time was significantly shorter in the manual SICS group (10.8±2.9 versus 13.2±2.6min) (P<0.001). Oral prednisolone, 1 mg/kg body weight was given 7d prior to surgery, continued post-operatively and tapered according to the inflammatory response over 4-6wk in patients with previously documented macular edema, recurrent uveitis, chronic anterior uveitis and intermediate uveitis. Rate of complications like macular edema (Chi-square, P=0.459), persistent uveitis (Chi-square, P=0.289) and posterior capsule opacification (Chi-square, P=0.474) were comparable between both the groups. CONCLUSION Manual SICS and phacoemulsification do not differ significantly in complication rates and final CDVA outcomes. However, manual SICS is significantly faster. It may be the preferred technique in settings where surgical volume is high and access to phacoemulsification is limited, such as in eye camps. It may also be the appropriate technique for uveitic cataract under such circumstances. PMID:26558210

    We develop a quantitative bioluminescence assay for in vivo longitudinal monitoring of inflammation in animal models of uveitis. Three models of experimental uveitis were induced in C57BL/6 albino mice: primed mycobacterial uveitis (PMU), endotoxin-induced uveitis (EIU), and experimental autoimmune uveitis (EAU). Intraperitoneal injection of luminol sodium salt, which emits light when oxidized, provided the bioluminescence substrate. Bioluminescence images were captured by a PerkinElmer In Vivo Imaging System (IVIS) Spectrum and total bioluminescence was analyzed using Living Image software. Bioluminescence on day zero was compared to bioluminescence on the day of peak inflammation for each model. Longitudinal bioluminescence imaging was performed in EIU and EAU. In the presence of luminol, intraocular inflammation generates detectable bioluminescence in three mouse models of uveitis. Peak bioluminescence in inflamed PMU eyes (1.46 × 105 photons/second [p/s]) was significantly increased over baseline (1.47 × 104 p/s, P = 0.01). Peak bioluminescence in inflamed EIU eyes (3.18 × 104 p/s) also was significantly increased over baseline (1.09 × 104 p/s, P = 0.04), and returned to near baseline levels by 48 hours. In EAU, there was a nonsignificant increase in bioluminescence at peak inflammation. In vivo bioluminescence may be used as a noninvasive, quantitative measure of intraocular inflammation in animal models of uveitis. Primed mycobacterial uveitis and EIU are both acute models with robust anterior inflammation and demonstrated significant changes in bioluminescence corresponding with peak inflammation. Experimental autoimmune uveitis is a more indolent posterior uveitis and generated a more modest bioluminescent signal. In vivo imaging system bioluminescence is a nonlethal, quantifiable assay that can be used for monitoring inflammation in animal models of uveitis.

    AIMS—To investigate whether routine testing for Epstein-Barr virus (EBV) is necessary in the examination of a patient with uveitis.
METHODS—Intraocular EBV DNA was determined in 183 ocular fluid samples taken from patients with AIDS and uveitis, HIV negative immunocompromised uveitis, acute retinal necrosis, toxoplasma chorioretinitis, intraocular lymphoma, anterior uveitis, and miscellaneous uveitis of unknown cause. In 82 samples from this group of patients paired serum/ocular fluid analysis was performed to detect local antibody production against EBV. Controls (n=46) included ocular fluid samples taken during surgery for diabetic retinopathy, macular pucker, or cataract.
RESULTS—Serum antibody titres to EBV capsid antigen proved to be significantly increased in HIV negative immunocompromised patients with uveitis (p<0.01) compared with controls. Local antibody production revealed only three positive cases out of 82 patients tested, two results were borderline positive and one patient had uveitis caused by VZV. EBV DNA was detected in three out of 46 control ocular fluid samples. In the different uveitis groups EBV DNA was noted, but was not significantly higher than in the controls, except in six out of 11 HIV negative immunocompromised patients (p=0.0008). In four out of these six cases another infectious agent (VZV, HSV, CMV, or Toxoplasma gondii) had previously been identified as the cause of the uveitis.
CONCLUSIONS—When comparing various groups of uveitis patients, EBV DNA was found more often in HIV negative immunocompromised patients with uveitis. Testing for EBV does not have to be included in the routine management of patients with uveitis, since indications for an important role of this virus were not found in the pathogenesis of intraocular inflammation.

    Animal models of autoimmunity to the retina mimic specific features of human uveitis, but no model by itself reproduces the full spectrum of human disease. We compared three mouse models of uveitis that target the interphotoreceptor retinoid binding protein (IRBP): (i) the “classical” model of experimental autoimmune uveitis (EAU) induced by immunization with IRBP; (ii) spontaneous uveitis in IRBP T cell receptor transgenic mice (R161H) and (iii) spontaneous uveitis in Autoimmune Regulator (AIRE)−/− mice. Disease course and severity, pathology and changes in visual function were studied using fundus imaging and histological examinations, optical coherence tomography and electroretinography. All models were on the B10.RIII background. Unlike previously reported, IRBP-induced EAU in B10.RIII mice exhibited two distinct patterns of disease depending on clinical scores developed after onset: severe monophasic with extensive destruction of the retina and rapid loss of visual signal, or lower grade with a prolonged chronic phase culminating after several months in retinal degeneration and loss of vision. R161H and AIRE−/− mice spontaneously developed chronic progressive inflammation; visual function declined gradually as retinal degeneration developed. Spontaneous uveitis in R161H mice was characterized by persistent cellular infiltrates and lymphoid aggregation, whereas AIRE−/− mice characteristically developed multi-focal infiltrates and severe choroidal inflammation. These data demonstrate variability and unique distinguishing features in the different models of uveitis, suggesting that each one can represent distinct aspects of uveitis in humans. PMID:24015215

    Chronic neuropathic pain is estimated to affect 3%-4.5% of the worldwide population. It is associated with significant loss of productive time, withdrawal from the workforce, development of mood disorders such as depression and anxiety, and disruption of family and social life. Current medical therapeutics often fail to adequately treat chronic neuropathic pain. Deep brain stimulation (DBS) targeting subcortical structures such as the periaqueductal gray, the ventral posterior lateral and medial thalamic nuclei, and the internal capsule has been investigated for the relief of refractory neuropathic pain over the past 3 decades. Recent work has identified the dorsal anterior cingulate cortex (dACC) as a new potential neuromodulation target given its central role in cognitive and affective processing. In this review, the authors briefly discuss the history of DBS for chronic neuropathic pain in the United States and present evidence supporting dACC DBS for this indication. They review existent literature on dACC DBS and summarize important findings from imaging and neurophysiological studies supporting a central role for the dACC in the processing of chronic neuropathic pain. The available neurophysiological and empirical clinical evidence suggests that dACC DBS is a viable therapeutic option for the treatment of chronic neuropathic pain and warrants further investigation.

    The incidence of uveitis associated with juvenile idiopathic arthritis (JIA) varies around the world. Our aim was to investigate the incidence and predictors of uveitis in a Nordic population-based cohort. Consecutive JIA cases from defined geographical areas in Denmark, Finland, Sweden and Norway with disease onset between January 1997 to June 2000 were followed for median 98 months in this prospective longitudinal cohort study. Potential clinical and immunological predictors of uveitis were identified with logistic regression analysis. Uveitis occurred in 89 (20.5%) of the 435 children with regular ophtalmologic follow-up among the 500 included. Chronic asymptomatic uveitis developed in 80 and acute symptomatic uveitis in 9 children. Uveitis developed at a median interval of 0.8 (range - 4.7 to 9.4) years after onset of arthritis. Predictors of uveitis were age < 7 years at JIA onset (Odds ratio (OR) 2.1, 95% confidence interval (CI) 1.3 to 3.5), presence of antihistone antibodies (AHA) > 15 U/ml (OR 4.8 (1.8 to 13.4)) and antinuclear antibodies (ANA) (OR 2.4 (1.5 to 4.0)). Mean combined IgM/IgG AHA was significantly higher in the uveitis group (19.2 U/ml) than in the non-uveitis group (10.2 U/ml) (p = 0.002). Young age at JIA onset predicted uveitis in girls (p < 0.001), but not in boys (p = 0.390). Early-onset arthritis and presence of AHA in girls, as well as presence of ANA in both genders, were significant predictors of chronic uveitis. The high incidence of uveitis in this long-term Nordic JIA cohort may have severe implications in a lifelong perspective.

    Chronic exertional compartment syndrome is characterized by exertional pain and elevated intracompartmental pressures affecting the leg in physically active young people. In patients who have failed conservative measures, fasciotomy is the treatment of choice. This study presents a new method for performing fasciotomy using high-resolution ultrasound (US) guidance and reports on the clinical outcomes in a group of these patients. Over a 3-year period, 7 consecutive patients with a total of 9 involved legs presented clinically with anterior compartment chronic exertional compartment syndrome, which was confirmed by intracompartmental pressure measurements before and after exercise. After a US examination, fasciotomy under US guidance was performed. Preoperative and postoperative pain and activity levels were assessed as well as number of days needed to "return to play." All patients had a decrease in pain, and all except 1 returned to presymptomatic exercise levels with a median return to play of 35 days. © 2016 by the American Institute of Ultrasound in Medicine.

    Abstract Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease of unknown etiology defined by the combination of tubulointerstitial nephritis, uveitis, and biochemical abnormalities. It has been reported that TINU mainly affects adolescents and young women. Here we reported a special case regarding a 60-year-old man with acute renal failure due to TINU syndrome documented by renal biopsy. We present a rare case of an elderly patient, who had been suffering from a fever for 2 weeks, characterized by sudden onset and resolving spontaneously, and accompanied by extreme fatigue, loss of appetite, and shivering. Renal biopsy showed a tubulointerstitial nephritis, with polymorphonuclear infiltration and acute tubulitis. In the outpatient clinic, he was diagnosed with idiopathic bilateral anterior uveitis 1 month ago. Ophthalmological examination revealed anterior asymptomatic bilateral uveitis. Human leukocyte antigen (HLA) typing (HLA-DQA1∗0101/0201 and HLA-DQB1∗0303/0503) was found which supported the suspect of TINU syndrome. The patient was treated with oral prednisone (1 mg/kg) and continued for 8 weeks on tapering doses. Serum creatinine normalized within 3 and 6 months later renal function also recovered completely. This case highlights that TINU syndrome is probably an underdiagnosed disease responsible for some cases of idiopathic anterior uveitis in elderly male patients. It is of critical importance to be aware of this syndrome by nephrologist and ophthalmologists in this special population. Further studies are needed to elucidate clinical characteristic and pathogenesis of TINU syndrome in elderly population. PMID:26632725

    Currently, the definitive diagnosis of chronic compartment syndrome is based on invasive measurements of intracompartmental pressure. We measured the intramuscular pressure and the relative oxygenation in the anterior compartment of the leg in eighteen patients who were suspected of having chronic compartment syndrome as well as in ten control subjects before, during, and after exercise. Chronic compartment syndrome was considered to be present if the intramuscular pressure was at least fifteen millimeters of mercury (2.00 kilopascals) before exercise, at least thirty millimeters of mercury (4.00 kilopascals) one minute after exercise, or at least twenty millimeters of mercury (2.67 kilopascals) five minutes after exercise. Changes in relative oxygenation were measured with use of the non-invasive method of near-infrared spectroscopy. In all patients and subjects, there was rapid relative deoxygenation after the initiation of exercise, the level of oxygenation remained relatively stable during continued exercise, and there was reoxygenation to a level that exceeded the pre-exercise resting level after the cessation of exercise. During exercise, maximum relative deoxygenation in the patients who had chronic compartment syndrome (mean relative deoxygenation [and standard error], -290 +/- 39 millivolts) was significantly greater than that in the patients who did not have chronic compartment syndrome (-190 +/- 10 millivolts) and that in the control subjects (-179 +/- 14 millivolts) (p < 0.05 for both comparisons). In addition, the interval between the cessation of exercise and the recovery of the pre-exercise resting level of oxygenation was significantly longer for the patients who had chronic compartment syndrome (184 +/- 54 seconds) than for the patients who did not have chronic compartment syndrome (39 +/- 19 seconds) and the control subjects (33 +/- 10 seconds) (p < 0.05 for both comparisons).

    The present studies examined the effect of chronic neuropathic pain on cannabinoid receptor density and receptor-mediated G-protein activity within supraspinal brain areas involved in pain processing and modulation in mice. Chronic constriction injury (CCI) produced a significant decrease in WIN 55, 212-2 -stimulated [35S]GTPγS binding in membranes prepared from the rostral anterior cingulate cortex (rACC) of CCI mice when compared to sham operated controls. Saturation binding with [3H]SR 141716A in membranes of the rACC showed no significant differences in binding between CCI and sham mice. Analysis of levels of the endocannabinoids anandamide (AEA) or 2-arachidonoylglycerol (2-AG) in the rACC following CCI showed no significant differences between CCI and sham mice. These data suggest that CCI produced desensitization of the cannabinoid 1 receptor in the rACC in the absence of an overall decrease in cannabinoid 1 receptor density or change in levels of AEA or 2-AG. These data are the first to show alterations in cannabinoid receptor function in the rostral anterior cingulate cortex in response to a model of neuropathic pain. PMID:20380816

    Objective To describe the risk and risk factors for hypotony in a non-infectious uveitis cohort. Design Retrospective cohort study. Participants Patients with non-infectious uveitis seen between 1979-2007 at four academic ocular inflammation specialty clinics. Method Data were collected by trained, certified, expert reviewers from medical records. Main Outcome Measures Hypotony (<5mmHg) and low intraocular pressure (<8mmHg), each sustained for ≥2 visits spanning at least 30 days. Results During follow-up, 126/6785 (1.86%) developed hypotony at the rate of 0.61%(95% Confidence Interval (CI) 0.50, 0.75%)/eye-year. Cataract surgery was associated with a 7.5-fold risk (adjusted hazard ratio (aHR = 7.51, 95% CI 3.97,14.23) of incident hypotony. Phacoemulsification, the type of cataract surgery associated with the least hypotony risk still was associated with nearly five-fold higher hypotony incidence (aHR =4.87, 95% CI 2.25, 10.55). Increased risk was observed in children (aHR =2.92, 95% CI 1.20, 7.10) with respect to young adults, and duration of uveitis of >5 years (aHR =3.08, 95% CI 1.30, 7.31) with respect to uveitis of <6 month duration. ≥3+ vitreous cells, band keratopathy, exudative retinal detachment, posterior synechia and history of pars plana vitrectomy also were associated with greater hypotony incidence. With respect to anterior uveitis, intermediate uveitis (aHR = 0.17, 95% CI 0.05,0.56) and posterior uveitis (aHR =0.11, 95% CI 0.03,0.45) were associated with lower hypotony risk, whereas panuveitis (aHR=1.25, 95% CI 0.67, 2.35) was similar. Approximately five-sixths (84.1%) of eyes presenting with hypotony had a visual acuity of 20/200 or worse (aOR for visual acuity 20/200 or worse=13.85, 95% CI 7.23, 26.53). Risk factors for prevalent hypotony were similar. Conclusions The risk of hypotony is low among eyes with non-infectious uveitis, but is more frequently observed in cases with anterior segment inflammation. Signs of present or past inflammation

    Two horses with chronic uveitis and histological lesions consistent with equine recurrent uveitis (ERU) were examined. Microscopical findings in the ciliary body included deposits of amyloid lining the non-pigmented epithelium, intracytoplasmic, rod-shaped, eosinophilic inclusions and intraepithelial infiltration of T lymphocytes. Ultrastructural examination of the ciliary body of one horse confirmed the presence of abundant extracellular deposits of non-branching fibrils (9-11 nm in diameter) consistent with amyloid. Immunohistochemistry revealed strong positive labelling for AA amyloid and mass spectrometry showed the amyloid to consist primarily of serum amyloid A1 in both cases. The findings suggest that localized, intraocular AA amyloidosis may occur in horses with ERU.

    Uveitis is the third leading cause of blindness in developed countries. Currently, the most widely used treatment of non-infectious uveitis is corticosteroids. Posterior uveitis and macular edema can be treated with intraocular injection of corticosteroids, however, this is problematic in chronic cases because of the need for repeat injections. Another option is systemic immunosuppressive therapies that have their own undesirable side effects. These systemic therapies result in a widespread suppression of the entire immune system, leaving the patient susceptible to infection. Therefore, an effective localized treatment option is preferred. With the recent advances in bioengineering, biodegradable polymers that allow for a slow sustained-release of a medication. These advances have culminated in drug delivery implants that are food and drug administration (FDA) approved for the treatment of non-infectious uveitis. In this review, we discuss the types of ocular implants available and some of the polymers used, implants used for the treatment of non-infectious uveitis, and bioengineered alternatives that are on the horizon.

    Surgery in the management of uveitis can be divided based on indication: either for therapeutic or can be for diagnostic purposes or to manage complications. The commonest indications include: Visual rehabilitation: surgery for removal of cataract, band keratopathy, corneal scars, pupillary membranes, removal of dense vitreous membranes, management of complications: anti-glaucoma surgery, vitreous hemorrhage, retinal detachment and chronic hypotony and diagnostic: aqueous tap, vitreous biopsy, tissue biopsy (iris, choroid). In this review, we shall describe the surgical technique for visual rehabilitation and for management of complications. PMID:23803480

    Results of the Latarjet procedure for chronic anterior shoulder instability using a coracoid block are known in terms of recurrence, but not in terms of apprehension. We studied a prospective consecutive series of shoulders treated with the Latarjet method in order to determine whether patients forget their shoulder or whether they are still bothered, particularly during sports activities. The series included 74 patients with chronic anterior shoulder instability treated with a coracoid block according to the Latarjet procedure. Sixty-nine were available for review and 66 had complete radiographic explorations (93.2%). The Duplay score was used to classify sports activities. Mean age was 26.5 years; 90% of the patients practiced sports. The surgical procedure was performed by the same operator for 78% of patients. The Duplay score and the Constant score were determined and standard x-rays (four views) were obtained. Statistical analysis was performed with the chi-square test. Multivariate analysis was then applied to the subpopulation presenting persistent apprehension. Follow-up was at least 24 months, average follow-up 50 months. Four patients presented secondary dislocation and two subluxation; 85% of patients were satisfied, 6% were hesitant and 9% were dissatisfied. The Duplay score was: excellent (18.8%), good (49.9%), fair (20.2%) and poor (10.1%). External elbow rotation (RE1) was limited by 17.69 degrees compared with the other side. Eighty-seven percent of patients resumed their sports activity five months postoperatively on average; 34% presented persistent apprehension. This subpopulation was examined separately. Multivariate analysis demonstrated two significantly independent factors of persistent apprehension: recovery of RE1 at 30 days postop, and total recovery of R1 at last follow-up. The radiographies demonstrated degenerative lesions in 10.6% of patients. The satisfaction rate of 85% and the 9% failure rate are similar to earlier reports. Our

    There is very limited evidence for the efficacy of any specific therapeutic intervention in chronic, treatment refractory major depression. Thermal anterior capsulotomy (ACAPS) is a rarely performed but established therapeutic procedure for this patient group. While benefit has been claimed, previous ACAPS reports have provided limited information. Detailed prospective reporting of therapeutic effects and side effects is required. To report a prospective study of therapeutic effect, mental status, quality of life, social functioning and neurocognitive functioning in individuals with chronic treatment refractory major depression, treated with ACAPS. A prospective case series of 20 patients treated with ACAPS between 1992 and 1999 were reassessed at a mean follow-up of 7.0±3.4 years. Data were collected preoperatively and at long term follow-up. Structural MRI was performed in 14 participants. According to a priori criteria, at long term follow-up, 50% were classified as 'responders' and 40% as 'remitters'. Fifty-five per cent were classified as 'improved'; 35% were 'unchanged'; and 10% had 'deteriorated'. Neurocognitive and personality testing were not significantly different at follow-up. A trend towards improvement in some aspects of executive neuropsychological functioning was observed. Significant adverse effects were infrequent and there were no deaths. ACAPS may represent an effective intervention for some patients with chronic, disabling, treatment refractory major depression that has failed to respond to other therapeutic approaches. The adverse effect burden within this population was modest, with no evidence of generalised impairment of neurocognitive functioning.

    Anterior ischemic optic neuropathy (AION) is characterized by infarction of the optic nerve head due to hypoperfusion of the posterior ciliary arteries and causes sudden blindness in adults on chronic dialysis, but has rarely been described in children. Unlike adults, children do not have comorbidities related to aging. We retrospectively analyzed data of 7 children on nocturnal continuous cycling peritoneal dialysis (CCPD) who developed AION identified within the Italian Registry of Pediatric Chronic Dialysis. We also summarized data from 10 cases reported in the literature. Our 7 patients suffered from acute onset bilateral blindness. Their mean age was 3.2 years and chronic hypotension had been observed prior the AION in 3 of the 7 children. Low systolic blood pressure (SBP) was associated with higher risk of developing AION according to statistical analysis. None recovered completely. In total, 11 out of 16 experienced a partial recovery and no clear evidence emerged favoring specific treatments. Hypotensive children treated with CCPD are at increased risk of developing AION, which often results in irreversible blindness. Copyright © 2015 International Society for Peritoneal Dialysis.

    Infectious causes should always be considered in all patients with uveitis and it should be ruled out first. The differential diagnosis includes multiple well-known diseases including herpes, syphilis, toxoplasmosis, tuberculosis, bartonellosis, Lyme disease, and others. However, clinicians should be aware of emerging infectious agents as potential causes of systemic illness and also intraocular inflammation. Air travel, immigration, and globalization of business have overturned traditional pattern of geographic distribution of infectious diseases, and therefore one should work locally but think globally, though it is not possible always. This review recapitulates the systemic and ocular mainfestations of several emergent infectious diseases relevant to the ophthalmologist including Rickettsioses, West Nile virus infection, Rift valley fever, dengue fever, and chikungunya. Retinitis, chorioretinitis, retinal vasculitis, and optic nerve involvement have been associated with these emergent infectious diseases. The diagnosis of any of these infections is usually based on pattern of uveitis, systemic symptoms and signs, and specific epidemiological data and confirmed by detection of specific antibody in serum. A systematic ocular examination, showing fairly typical fundus findings, may help in establishing an early clinical diagnosis, which allows prompt, appropriate management. PMID:20404989

    Purpose The aim of this study was to evaluate the characteristics and outcomes of pediatric uveitis cases at a large tertiary referral center in Dallas, TX, USA. Materials and methods The authors performed a retrospective chart review between 2001 and 2011 to identify children with uveitis. Results A total of 46 children (68 eyes) with uveitis were identified. Sixty-seven percent were Hispanic, and the mean age was 9.2 years. The majority of cases were idiopathic (74%). Anterior uveitis accounted for 42% of cases followed by intermediate uveitis/pars planitis (33%), posterior uveitis/retinitis (7%), and panuveitis (20%). Most patients were treated with corticosteroids (98% topical), 52% with systemic immunosuppression therapy, and 30% with surgery. Complications occurred in 74% of patients, with the most common complication being cataract development (26%), followed by posterior synechiae (24%). Twenty-four percent of patients had recurrences. Hispanic patients had worse visual acuities at presentation (P-value =0.073) and follow-up (P-value =0.057), compared to non-Hispanic patients. Conclusion Pediatric uveitis cases seen in a large center in Dallas were largely idiopathic, had commonly developed complications, and were associated with worse visual outcomes in Hispanic patients.

    BACKGROUND It is important for an ophthalmologist and nephrologist to look for hidden causes of uveitis and nephritis, respectively. Delay in diagnosis leads to increased morbidity and failure to systemically manage the patient results in future recurrence of disease. It is likely that TINU remains underdiagnosed and could potentially account for some of the cases of idiopathic uveitis, especially when greater than 50% of uveitis cases have no identifiable cause. Fewer than 300 cases of tubulointerstitial nephritis and uveitis (TINU) syndrome have been reported. In TINU syndrome, inflammation affects the renal tubules, interstitial tissue, and uveal tract. Its pathogenesis remains poorly understood. CASE REPORT We report a rare case of TINU syndrome in a 23-year-old female who was treated using a multispecialty approach. Her primary care physician diagnosed her with proteinuria and acute kidney injury and referred her to the nephrologist, who later referred her to the ophthalmologist. A left kidney biopsy confirmed acute interstitial nephritis. Following the discovery of a "pink eye", the patient was referred to ophthalmology and diagnosed with anterior uveitis, confirming TINU syndrome. Without the additional findings of uveitis, the diagnosis would have been missed. Resolution was obtained through steroid therapy. CONCLUSIONS Correctly diagnosing TINU syndrome requires a multispecialty approach and may not be obvious upon initial presentation. Therefore, the ophthalmologist needs to consider TINU in the differential diagnosis for a patient with bilateral uveitis and evaluate a urinalysis for proteinuria as part of the work up.

    The evidence base to guide therapeutic choices for patients with chronic and treatment-refractory depression (TRD) remains weak. There is limited comparative information available to guide the choice of intervention for patients with the most severe and disabling forms of illness. The aim of this work was to describe the 12-month clinical outcomes of patients with chronic TRD treated with anterior capsulotomy (ACAPS; n = 5), anterior cingulotomy (ACING; n = 5) or vagus nerve stimulation (VNS; n = 5). We performed a retrospective, consecutive, case series comparison. With clinical response defined as a ≥50% reduction from the baseline MADRS score, response rates were 40% for ACAPS, 60% for ACING and 20% for VNS. Adverse effects from all three procedures were relatively mild, consistent with previous reports and, in most cases, transient. Adverse effects from VNS were related to active stimulation, and were modifiable and diminished in severity over time. There were no deaths. Although based on a small sample, our data represent a unique comparison of ACAPS, ACING and VNS for chronic TRD. The three cohorts were broadly equivalent in terms of baseline clinical characteristics, indices of chronicity, illness severity and estimates of previous failed treatments. ACING and ACAPS, but not VNS, were associated with favourable response rates at 12 months. © 2015 S. Karger AG, Basel.

    Abstract Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease, defined by the association of idiopathic acute TINU. The aim of our work was to determine the characteristics of adult TINU syndrome in France, and to assess factors (including treatment) influencing medium-term prognosis. We conducted a nationwide study including 20 French hospitals. Clinical, laboratory, and renal histopathologic data of 41 biopsy-proven TINU syndromes were retrospectively collected. The patients were diagnosed between January 1, 1999 and December 1, 2015. Twenty-five females and 16 males were included (F/M ratio: 1.6:1). The median age at disease onset was 46.8 years (range 16.8–77.4) with a median serum creatinine level at 207 μmol/L (range 100–1687) and a median estimated glomerular filtration rate (eGFR) at 27 mL/min per 1.73 m2 (range 2–73). Twenty-nine patients (71%) had a bilateral anterior uveitis and 24 (59%) had deterioration in general health at presentation. Moderate proteinuria was found in 32 patients (78%) (median proteinuria 0.52 g/24 h; range 0.10–2.10), aseptic leukocyturia in 25/36 patients (70%). The evaluation of renal biopsies revealed 41 patients (100%) with an acute tubulointerstitial nephritis, 19/39 patients (49%) with light to moderate fibrosis and 5 patients (12%) with an acute tubular necrosis. Thirty-six patients (88%) were treated with oral corticosteroids. After 1 year of follow-up, the median eGFR was 76 mL/min per 1.73 m2 (range 17–119) and 32% of the patients suffered from moderate to severe chronic kidney disease. Serum creatinine (P < 0.001, r = −0.54), serum bicarbonate and phosphate levels (respectively, P = 0.01, r = 0.53; and P = 0.04, r = 0.46), and age (P = 0.03, r = −0.37) at the 1st symptoms were associated with eGFR after 1 year. During the 1st year 40% of patients had uveitis relapses. The use of oral corticosteroids was not associated with a better kidney function but was associated

    To describe a patient with Hodgkin disease with posterior uveitis who also had a thinning of the retina and an antiretinal autoantibody in his serum. Our patient was a 58-year-old man who had been diagnosed with Hodgkin disease. He had a complete ophthalmologic examination including fluorescein angiography, electroretinography, perimetry, and spectral-domain optical coherence tomography. A search for antiretinal antibodies in the serum was made by Western blot analysis, and the retinal sites reactive to the antibodies were determined by immunohistochemistry. The ocular signs were mild cellular infiltration in the anterior chamber and vitreous, and small, round chorioretinal lesions in the peripheral retina. The electroretinograms were slightly reduced. Small ring-like scotomas were detected in the Goldmann visual fields. An antiretina-specific 116-kDa antibody was detected in the serum by Western blot analysis, and the antibody reacted with the ganglion cell and inner nuclear layers of mice retinas. Although the visual acuities were maintained for over eight years, the macular thickness measured in the spectral-domain optical coherence tomography images was reduced. The presence of an antiretinal autoantibody, granulomatous uveitis, and retinal thinning in a patient with Hodgkin disease suggests that the patient had a granulomatous uveitis associated with Hodgkin disease or lymphoma-associated uveitis with retinal involvement.

    Two colour flow cytometry techniques were used to assess the activation stages of peripheral and intraocular T lymphocytes in uveitis. Increased numbers of T lymphocytes bearing the interleukin-2 (IL-2) receptors were found in intraocular fluids or peripheral blood or both of 35/51 patients with uveitis. This increased expression of IL-2 receptors on lymphocytes correlated with increased expression of other early T lymphocyte activation markers, HLA-DR and L-35. Both T helper cells (Leu-3A+) and suppressor cells (Leu 2A+) were activated in vivo. A positive correlation was seen between lymphocyte activation and clinical uveitis activity. In idiopathic uveitis activation of Leu-3A lymphocytes (helper/inducer) was significantly increased, and intraocular activation of the Leu-2A lymphocytes (cytotoxic/suppressor) was significantly decreased. These data show that some patients with idiopathic uveitis have a perturbation of T helper cells. Twenty-two of 31 patients with idiopathic uveitis, not associated with systemic disease, had increased peripheral T lymphocyte activation. This finding indicates that in some inflammations believed to be restricted to the eye an abnormal systemic immune activation exists. PMID:2964862

    This retrospective clinical study describes the clinical manifestations, light microscopic findings, and diagnosis and treatment of acute and chronic lens rupture in the horse. Rupture of the lens capsule in the horse usually results in a chronic, blinding inflammation (phacoclastic uveitis) unless prompt surgical and medical therapies are implemented. The clinical manifestations of acute lens capsule rupture included: cataract; intralenticular displacement of iridal pigment; lens cortical fragments attached to the perforated lens capsule, iris, and corneal endothelium; miosis; aqueous flare; and usually a corneal or scleral perforation with ulceration or focal full thickness corneal edema and scarring. The clinical signs of chronic phacoclastic uveitis include blindness, phthisis bulbi, and generalized corneal opacification related to scarring, vascularization, pigmentation, and edema. In one horse, acute phacoclastic uveitis was successfully treated with phacoemulsification to remove the ruptured lens and medical therapy to control the accompanying inflammation. The affected eyes of the horses with chronic phacoclastic uveitis were enucleated because of persistent clinical signs of nonulcerative keratitis and uveitis, despite long-term medical management. The clinical manifestations and lack of improvement with medical therapy are similar in the horse, dog, cat, and rabbit. However, the histologic findings in equine phacoclastic uveitis differ significantly from those in the dog, and rabbit. Images Figure 1. Figure 2. Figure 3. Figure 4. Figure 5. Figure 6. Figure 7.

    We hereby describe a 49-year-old woman with acute renal failure due to tubulointerstitial nephritis and uveitis (TINU) syndrome. This patient presented with vomiting and nausea and was found to have chronic uveitis, elevated creatinine, and interstitial nephritis. The combination of tubulointerstitial nephritis and uveitis emerged the diagnosis of TINU syndrome after a stepwise examination for differential diagnosis. Clinical course and renal function improved quickly on oral steroids but not to normal range. TINU syndrome, although known to some ophthalmologists and nephrologists, is still rather obscure. TINU syndrome should be considered in patients with uveitis in combination with acute renal failure. The prognosis for the renal disorder is excellent, although the uveitis often recurs or remains chronic.

    Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease of unknown etiology defined by the combination of tubulointerstitial nephritis, uveitis, and biochemical abnormalities. It has been reported that TINU mainly affects adolescents and young women. Here we reported a special case regarding a 60-year-old man with acute renal failure due to TINU syndrome documented by renal biopsy.We present a rare case of an elderly patient, who had been suffering from a fever for 2 weeks, characterized by sudden onset and resolving spontaneously, and accompanied by extreme fatigue, loss of appetite, and shivering. Renal biopsy showed a tubulointerstitial nephritis, with polymorphonuclear infiltration and acute tubulitis. In the outpatient clinic, he was diagnosed with idiopathic bilateral anterior uveitis 1 month ago. Ophthalmological examination revealed anterior asymptomatic bilateral uveitis. Human leukocyte antigen (HLA) typing (HLA-DQA1*0101/0201 and HLA-DQB1*0303/0503) was found which supported the suspect of TINU syndrome. The patient was treated with oral prednisone (1 mg/kg) and continued for 8 weeks on tapering doses. Serum creatinine normalized within 3 and 6 months later renal function also recovered completely.This case highlights that TINU syndrome is probably an underdiagnosed disease responsible for some cases of idiopathic anterior uveitis in elderly male patients. It is of critical importance to be aware of this syndrome by nephrologist and ophthalmologists in this special population. Further studies are needed to elucidate clinical characteristic and pathogenesis of TINU syndrome in elderly population.

    Purpose. To report one-year results of phacoemulsification combined with deep sclerectomy and goniosynechiolysis ab interno for chronic glaucoma associated with peripheral anterior synechiae (PAS). Methods. We retrospectively analyzed medical charts of 16 patients (20 eyes) treated by one-site combined phacoemulsification and deep sclerectomy with goniosynechiolysis ab interno. PAS were transected by a spatula introduced into the anterior chamber through a paracentesis. To account for the correlation of right and left eyes a linear mixed model with unstructured covariance structure was calculated. Results. The mean preoperative intraocular pressure (IOP) was 20.3 ± 5.2 mmHg with 2.4 ± 1.0 medications. One year postoperatively, the mean IOP was 15.3 ± 3.3 mmHg (P = 0.004, paired t-test) with 0.6 ± 1.0 medications. A postoperative IOP of ≤21 mmHg without medication was achieved in 17 of 19 eyes (89.5%) and in 12/19 eyes (63.2%) at 3 and 12 months after surgery, respectively. In the remaining eyes (10.5% at 3 months and 36.8% at 12 months), additional medication led to an IOP ≤21 mmHg or the target pressure. No case required further glaucoma surgery. In one eye, conversion of the surgery to trabeculectomy was necessary due to Descemet's window rupture. Conclusions. With goniosynechiolysis ab interno, effective and safe nonpenetrating glaucoma surgery is possible in presence of PAS. PMID:26199738

If so, heterogeneity in processes may be a function of the spatial organization of the paranasal sinuses. Density characteristics of sinus opacities on computed tomography (CT) scans offer insight into the nature of sinus opacities and disease, in general, and may thus be used to detect spatial heterogeneity of sinus disease within a given patient. The study was a retrospective chart review of CRS patients with available sinus CT scans. Radiographic density profiles of sinus opacities were assessed by raw measures of densities (in Hounsfield units [HU]). Radiographic density profiles of the different affected sinuses were compared to each other, checked for correlation, and finally, checked for evidence of clustering using a principal component analysis. Frontal sinus opacities appear to be more heterogeneous, with both higher and lower density components than other sinuses. There was strong correlation between the radiographic density profiles of opacities in the frontal, anterior ethmoid, and sphenoid sinuses (p < 0.001). However, on principal component analysis the radiographic density characteristics of the opacities of the frontal and anterior ethmoid sinuses appeared to cluster together more than the other sinuses. Radiographic properties of sinus opacities suggest the nature of sinus opacities are related not only to some common underlying pathology but also to factors related to the specific sinus as well as other spatially close affected sinuses. This suggests an anatomic orientation for sinus pathophysiology in CRS. Copyright © 2012 American Rhinologic Society-American Academy of Otolaryngic Allergy, LLC.

    Objectives: To evaluate the clinical and demographic properties of Fuchs’ uveitis syndrome (FUS) in Turkish patients. Materials and Methods: The medical records of 161 patients with FUS followed in the Uveitis Division of Ulucanlar Eye Hospital between 1996 and 2014 were respectively reviewed. The mean age at diagnosis, sex, the number of affected eyes, follow-up period, clinical findings at presentation, complications during the follow-up period, medical and surgical treatments, and best corrected visual acuity at the initial and final visits were recorded. Results: The study included 171 eyes of 161 patients diagnosed with FUS. Of the patients, 94 (58.4%) were female and 67 (41.6%) were male. The mean age at presentation was 35.2±11.0 (11-65) years. The mean follow-up period was 23.5±32.8 (2-216) months. Ten (6.2%) patients had bilateral involvement. The most common symptoms at presentation were decreased visual acuity or blurred vision in 63 (39.1%) and floaters in 19 (11.8%) patients. Clinical findings at presentation included diffuse small, round, white keratic precipitates in 128 (74.8%) eyes, anterior chamber reaction in 82 (47.9%), vitreous cells in 122 (71.3%), heterochromia in 47 (27.4%) and iris nodules in 32 (18.7%) eyes. During the follow-up period, elevated intraocular pressure occured in 31 (18.1%) eyes and the most common complication was cataract development (89 eyes, 52.0%). Conclusion: Heterochromia was observed in 27.4% of patients in our study. However, the diffuse small, round keratic precipitates, low-grade anterior chamber reaction and varying degrees of vitreous reaction are more common clinical characteristics that are helpful in making the diagnosis.

    Purpose. To review the clinical outcome of patients with hypertensive uveitis. Methods. Retrospective review of uveitis patients with elevated intraocular pressure (IOP) > 25 mmHg and >1-year follow-up. Data are uveitis type, etiology, viral (VU) and nonviral uveitis (NVU), IOP, and medical and/or surgical treatment. Results. In 61 patients, IOP values are first 32.9 mmHg (SD: 9.0), highest 36.6 mmHg (SD: 9.9), 3 months after the first episode 19.54 mmHg (SD: 9.16), and end of follow-up 15.5 mmHg (SD: 6.24). Patients with VU (n = 25) were older (50.6 y/35.7 y, p = 0.014) and had more unilateral disease (100%/72.22%  p = 0.004) than those with NVU (n = 36). Thirty patients (49.2%) had an elevated IOP before topical corticosteroid treatment. Patients with viral uveitis might have higher first elevated IOP (36.0/27.5 mmHg, p = 0,008) and maximal IOP (40.28/34.06 mmHg, p = 0.0148) but this was not significant when limited to the measurements before the use of topical corticosteroids (p = 0.260 and 0.160). Glaucoma occurred in 15 patients (24.59%) and was suspected in 11 (18.03%) without difference in viral and nonviral groups (p = 0.774). Conclusion. Patients with VU were older and had more unilateral hypertensive uveitis. Glaucoma frequently complicates hypertensive uveitis. Half of the patients had an elevated IOP before topical corticosteroid treatment. PMID:26504598

    To assess anti-TNF-α therapy response in uveitis associated with sarcoidosis refractory to conventional immunosuppressive therapy. Open-label, multicenter, retrospective study on patients with sarcoid uveitis who underwent anti-TNF-α therapy because of inadequate response to conventional therapy including corticosteroids and at least 1 systemic synthetic immunosuppressive drug. The main outcome measurements were degree of anterior and posterior chamber inflammation, visual acuity, macular thickness, and immunosuppression load. A total of 17 patients (8 men; 29 affected eyes; mean ± standard deviation age 38.4 ± 16.8; range: 13-76 years) were studied. The patients had bilateral hilar lymphadenopathy (58.8%), lung parenchyma involvement (47.1%), peripheral lymph nodes (41.2%), and involvement of other organs (52.9%). Angiotensin-converting enzyme was elevated in 58.8%. The most frequent ocular pattern was bilateral chronic relapsing panuveitis. The first biologic agent used was adalimumab in 10 (58.8%) and infliximab in 7 (41.2%) cases. Infliximab 5mg/kg intravenously every 4-8 weeks and adalimumab 40mg subcutaneously every 2 weeks were the most common administration patterns. In most cases anti-TNF-α therapy was given in combination with immunosuppressive drugs. The mean duration of follow-up was 33.9 ± 17.1 months. Significant improvement was observed following anti-TNF-α therapy. Baseline results versus results at 2 years from the onset of biologic therapy were the following: the median of cells in the ocular anterior chamber (interquartile range-IQR) 0.5 (0-2) versus 0 (0-0) (p = 0.003), vitritis 0 (0-1.25) versus 0 (0-0) (p = 0.008), macular thickness (391.1 ± 58.8 versus 247 ± 40.5µm) (p = 0.028), and visual acuity 0.60 ± 0.33 versus 0.74 ± 0.27; p = 0.009. The median daily (interquartile range) dose of prednisone was also reduced from 10 (0-30)mg at the onset of the anti-TNF-α therapy to 0 (0-0)mg at 2 years (p = 0.02). Significant reduction was

    It is largely unknown how invading autoreactive T cells initiate the pathogenic process inside the diseased organ in organ-specific autoimmune diseases. In experimental autoimmune uveitis (EAU) induced by uveitogenic, interphotoreceptor retinoid-binding protein (IRBP)-specific T cells (tEAU) in mice, we have previously reported that high mobility group box 1 (HMGB1) released as a consequence of the direct interaction between IRBP-specific T cells and retinal parenchymal cells is an early and critical mediator in induction of intraocular inflammation. Our present study explored the roles of HMGB1 in intraocular inflammation, focusing on its role in recruiting inflammatory cells into the eye. Our results showed that supernatants from retinal explants either stimulated with HMGB1 or cocultured with IRBP-specific T cells attracted leukocytes. Notably, HMGB1 antagonists blocked supernatant-induced chemoattraction when present from the start of coculture, but not when added to the culture supernatants after coculture, indicating that molecules released by HMGB1-treated retinal cells are chemoattractive. Moreover, CXCL12 levels in the coculture supernatants were dependent on HMGB1, since they were increased in the cocultures and reduced when HMGB1 antagonists were added at the beginning of the coculture. When either anti-CXCL12 Ab was added to the supernatants after coculture or the responding lymphocytes were pretreated with Ab against CXCL12 specific receptor, CXCR4, chemoattraction by the coculture supernatants was decreased. Finally, induction of tEAU was significantly inhibited by a CXCR4 antagonist, AMD3100, at the time of autoreactive T cell transfer. Our study demonstrates that, at a very early stage of intraocular inflammation initiated by uveitogenic autoreactive T cells, synergism between HMGB1 and CXCL12 is crucial for the infiltration of inflammatory cells.

    Deep brain stimulation (DBS) has been investigated for the treatment of epilepsy. In rodents, an increase in the latency for the development of seizures and status epilepticus (SE) has been reported in different animal models but the consequences of delivering stimulation to chronic epileptic animals have not been extensively addressed. We study the effects of anterior thalamic nucleus (AN) stimulation at different current intensities in rats rendered epileptic following pilocarpine (Pilo) administration. Four months after Pilo-induced SE, chronic epileptic rats were bilaterally implanted with AN electrodes or had sham-surgery. Stimulation was delivered for 6 h/day, 5 days/week at 130 Hz, 90 µsec. and either 100 µA or 500 µA. The frequency of spontaneous recurrent seizures in animals receiving stimulation was compared to that recorded in the preoperative period and in rats given sham treatment. To investigate the effects of DBS on hippocampal excitability, brain slices from animals receiving AN DBS or sham surgery were studied with electrophysiology. We found that rats treated with AN DBS at 100 µA had a 52% non-significant reduction in the frequency of seizures as compared to sham-treated controls and 61% less seizures than at baseline. Animals given DBS at 500 µA had 5.1 times more seizures than controls and a 2.8 fold increase in seizure rate as compared to preoperative values. In non-stimulated controls, the average frequency of seizures before and after surgery remained unaltered. In vitro recordings have shown that slices from animals previously given DBS at 100 µA had a longer latency for the development of epileptiform activity, shorter and smaller DC shifts, and a smaller spike amplitude compared to non-stimulated controls. In contrast, a higher spike amplitude was recorded in slices from animals given AN DBS at 500 µA. PMID:24892420

  9. Repair of Chronic Tibialis Anterior Tendon Rupture With a Major Defect Using Gracilis Allograft.

    Tibialis anterior tendon (TAT) rupture is an uncommon injury, however, it can cause substantial deficit. Diagnosis is often delayed due to lack of initial symptoms; yet loss of function over time typically causes the patient to present for treatment. This delay usually ends up with major defects creating a great technical challenge for the operating surgeon. We present a novel technique and operative algorithm for the management of chronic TAT ruptures with a major gap after a delayed diagnosis not otherwise correctable with currently described techniques in the literature. This technique has been performed in 4 cases without any complications with fairly successful functional outcomes. For the reconstruction of chronic TAT rupture with an average delay of nine weeks after initial injury and gap of greater than 10 cm, a thorough operative algorithm was implemented in 4 patients using a double bundle gracilis allograft. Patients were then kept nonweightbearing for 6 weeks followed by weightbearing as tolerated. They began physical therapy with a focus on ankle exercises and gradual return to normal activity at 8 weeks, with resistance training exercises allowed at 12 weeks. At a mean follow-up time of 24.5 months, all patients reported significant pain relief with normal gait pattern. There were no reported intra- or postoperative complications. The average Foot and Ankle Ability Measure score increased to 90 from 27.5 in the postoperative period. All patients were able to return their previous activity levels. Gracilis allograft reconstruction as used in this study is a viable and reproducible alternative to primary repair with postoperative results being favorable without using complex tendon transfer techniques or autograft use necessitating the functional sacrifice of transferred or excised tendon. To the best of our knowledge, this is the first study demonstrating a successful technique and operative algorithm of gracilis allograft reconstruction of the TAT

    Patient characteristics associated with the course and severity of low back pain (LBP) and disability have been the focus of extensive research, however, known characteristics do not explain much of the variance in outcomes. The relationship between anterior trunk pain (ATP) and LBP has not been explored, though mechanisms for visceral referred pain have been described. Study objectives were: (1) determine prevalence of ATP in chronic LBP patients, (2) determine whether ATP is associated with increased pain and disability in these patients, and (3) evaluate whether ATP predicts the course of pain and disability in these patients. In this study, spinal outpatient department patients mapped the distribution of their pain and patients describing pain in their chest, abdomen or groin were classified with ATP. Generalized estimating equations were performed to investigate the relationship between ATP and LBP outcomes. A total of 2974 patients were included and 19.6% of patients reported ATP. At all time points, there were significant differences in absolute pain intensity and disability in those with ATP compared with those without. The presence of ATP did not affect the clinical course of LBP outcomes. The results of this study suggest that patients who present with LBP and ATP have higher pain and disability levels than patients with localised LBP. Visceral referred pain mechanisms may help to explain some of this difference.

    ABSTRACT Aims: To report a case of a patient who developed uveitis-glaucoma-hyphema (UGH) syndrome after an uneventful cataract surgery and to discuss risk factors, diagnostic challenges, management options, and clinical implications. Background: Uveitis-glaucoma-hyphema syndrome is a rare but potentially serious cataract surgery complication. Clinical manifestations include increased intraocular pressure (IOP), anterior chamber inflammation, and recurrent hyphema or microhyphema. Uveitis-glaucoma-hyphema Plus syndrome also includes accompanying vitreous hemorrhage. Although classically associated with rigid anterior chamber intraocular lenses (lOLs), cases of malpositioning and subluxated posterior chamber lOLs have also been described as possible triggers. Case description: We report a case of a 70-year-old Caucasian man who developed UGH Plus syndrome after an uneventful cataract surgery with an lOL implanted in the capsular bag. During postoperative follow-up, persistent intraocular inflammation, increased IOP, hyphema, and vitreous hemorrhage were consistent with this diagnosis. Slit-lamp examination demonstrated progressive localized iris atrophy, compatible with chafing of the posterior iris by the IOL haptic as the trigger for UGH syndrome. A pars plana vitrectomy was performed and a retropupillary intraocular lens was implanted. No further complications occurred during follow-up. Conclusion and clinical significance: Given the increasing prevalence of single-piece lOLs implanted in the capsular bag, it is important to recognize UGH syndrome as a rare but potentially serious complication.

    This study was initiated to induce experimental autoimmune anterior uveitis (EAAU) in Lewis rats by melanin-associated antigen (MAA; 22-kDa fragment of type I collagen α2 chain) derived from rat iris and ciliary body (CB), to localize MAA within the eye, and to investigate the possible mechanism of MAA generation in vivo. The EAAU model replicates idiopathic human anterior uveitis. Lewis rats sensitized to rat MAA developed anterior uveitis, and EAAU induced by rat MAA can be adoptively transferred to naive syngenic rats by MAA-primed T cells. Animals immunized with rat MAA developed cellular immunity to the antigen. MAA was detected only in the iris and CB of the eye. Iris and CB were the major source of matrix metalloproteinase-1 (MMP-1) in the naive eye, and ocular expression of MMP-1 was up-regulated, whereas expression of tissue inhibitor of metalloproteinase 1 decreased before the onset of EAAU. These results demonstrated that EAAU can be induced by autologous MAA. Uveitogenic antigen is present only in the iris and CB of the eye, and the imbalance between MMP-1 and tissue inhibitor of metalloproteinase 1 may play a role in the generation of MAA in vivo. Collectively, the evidence presented here suggests that MAA is an autoantigen in EAAU. These observations may extend to idiopathic human anterior uveitis and facilitate the development of antigen-specific therapy. PMID:19755419

    Uveitis refers to diseases characterized by intraocular inflammation of the uveal tract. Anterior uveitis is a common ocular disease characterized by inflammation of the iris and the ciliary body. To establish the frequency of HLA-B27-positive uveitis in Asian Indian population, study their clinical profile and compare it with other reports in literature. We retrospectively reviewed medical data of 89 patients of uveitis referred for HLA B27 typing with predominantly ocular symptoms during the period from April 2006-October 2010. All patients were tested for complete blood count, erythrocyte sedimentation rate, infectious diseases serology, HLA-B27 typing, and prepared radiographs of the sacroiliac joints and lumbar spine if required. The HLA-B27 positive rate was 56.2% among patients and 3% for control samples. Most of the patients were in the age group of 41-50 years with a male predominance. HLA-B27 was seen to be associated with acute anterior uveitis in Asian Indian males and the test is important for confirmation of diagnosis, prognostication and also for planning the treatment.

    Literature reports on ophthalmological manifestations related to tularemia, a zoonose caused by the bacterium Francisella tularensis, largely refer to Parinaud's oculoglandular syndrome, which consists of the association of conjunctivitis with preauricular lymphadenitis. In this paper, we report a case of intraocular inflammation during tularemia infection. A 52-year-old Caucasian man was diagnosed with unilateral uveitis. The uveitis was posterior, with a 2+ vitritis and a large yellowish lesion involving the macula with an overlying sub-retinal detachment, extending inferiorly, and subretinal hemorrhages. Fluorescein angiography showed a late hyperfluorescence with focal vascular leakage. Ultrasound biomicroscopy confirmed the presence of a 3.8 mm parietal granuloma with a few calcifications in the left eye. While extensive work-up eliminated any other infectious and non-infectious etiology, tularemia was diagnosed by advanced serology consisting of two-dimensional Western-immunoblotting. The patient, a hunter, recalled having killed rabbits in the days before the symptoms appeared. Uveitis was rapidly controlled following treatment with doxycycline, yet three years after initiation of the treatment, the patient still complained of loss of vision in the left eye with a central scotoma. Posterior uveitis may be an infrequent manifestation of tularemia infection, and therefore this infection should be considered in the differential diagnosis of intraocular inflammation in areas where F. tularensis is endemic.

    The purpose of the current study was to investigate the effects of aging on tendon response to repetitive exposures of stretch-shortening cycles (SSC's). The left hind limb from young (3 mo, N = 4) and old (30 mo, N = 9) male Fisher 344 x Brown Norway rats were exposed to 80 maximal SSCs (60 deg/s, 50 deg range of motion) 3 x/week for 4.5 weeks in vivo. After the last exposure, tendons from the tibialis anterior muscle were isolated, stored at -80 degrees C, and then tested using a micro-mechanical testing machine. Deformation of each tendon was evaluated using both relative grip-to-grip displacements and reference marks via a video system. At failure, the young control tendons had higher strain magnitude than the young exposed (p < 0.01) and the old control tendons (p < .0001). Total load at inflection was affected by age only (p < 0.01). Old exposed and control tendons exhibited significantly higher loads at the inflection point than their young counterparts (p < 0.05 for both comparisons). At failure, the old exposed tendons carried higher loads than the young exposed tendons (p < 0.05). Stiffness was affected by age only at failure where the old tendons exhibited higher stiffness in both exposed and control tendons than their young counterparts (p < 0.05 and p < 0.01, respectively). The chronic protocol enhanced the elastic stiffness of young tendon and the loads in both the young and old tendons. The old exposed tendons were found to exhibit higher load capacity than their younger counterparts, which differed from our initial hypothesis.

    The purpose of the study was to assess the rate of protein synthesis (PS) and elucidate signalling pathways regulating PS in mouse soleus (Sol) and tibialis anterior (TA) muscles following chronic hypergravity (30-day centrifugation at 2G). The content of the key signalling proteins of the various anabolic signalling pathways was determined by Western-blotting. The rate of PS was assessed using in-vivo SUnSET technique. An exposure to 2G centrifugation did not induce any significant changes in the rate of PS as well as phosphorylation status of the key anabolic markers (AKT, p70s6k, 4E-BP1, GSK-3beta, eEF2) in Sol. On the contrary, a significant 55% increase in PS (p < 0.05) was found in TA. The cause of such a rise in PS could be associated with an increase in AKT (+72%, p < 0.05), GSK-3beta (+60%, p < 0.05) and p70s6k (+40%, p < 0.05) phosphorylation, as well as a decrease in eEF2 phosphorylation (-46%, p < 0.05) as compared to control values. Thus, the results of our study indicate that 30-day 2G centrifugation induces a distinct anabolic response in mouse Sol and TA muscles. The activation of the PS rate in TA could be linked to an up-regulation of both mTORC1-dependent and mTORC1-independent signalling pathways.

    Autoimmune uveitis (AU), an inflammatory non-infectious process of the vascular layer of the eye, can lead to visual impairment and, in the absence of a timely diagnosis and suitable therapy, can even result in total blindness. The majority of AU cases are idiopathic, whereas fewer than 20 % are associated with systemic diseases. The clinical severity of AU depends on whether the anterior, intermediate, or posterior part of the uvea is involved and may range from almost asymptomatic to rapidly sight-threatening forms. Race, genetic background, and environmental factors can also influence the clinical picture. The pathogenetic mechanism of AU is still poorly defined, given its remarkable heterogeneity and the many discrepancies between experimental and human uveitis. Even so, the onset of AU is thought to be related to an aberrant T cell-mediated immune response, triggered by inflammation and directed against retinal or cross-reactive antigens. B cells may also play a role in uveal antigen presentation and in the subsequent activation of T cells. The management of AU remains a challenge for clinicians, especially because of the paucity of randomized clinical trials that have systematically evaluated the effectiveness of different drugs. In addition to topical treatment, several different therapeutic options are available, although a standardized regimen is thus far lacking. Current guidelines recommend corticosteroids as the first-line therapy for patients with active AU. Immunosuppressive drugs may be subsequently required to treat steroid-resistant AU and for steroid-sparing purposes. The recent introduction of biological agents, such as those targeting tumor necrosis factor-α, is expected to remarkably increase the percentages of responders and to prevent irreversible sight impairment. This paper reviews the clinical features of AU and its crucial pathogenetic targets in relation to the current therapeutic perspectives. Also, the largest clinical trials

    Chronic locked anterior shoulder dislocation is a difficult clinical problem for patients and surgeons. Prior studies have proposed a variety of surgical techniques to address this problem; however, the failure rate is high. To our knowledge, there have been no previously published studies on the clinical outcome of the Latarjet procedure for the treatment of chronic locked anterior shoulder dislocation. The purpose of this study was to evaluate the short-term subjective, objective, and radiographic outcomes of patients with chronic locked anterior shoulder dislocation after a Latarjet procedure. From January 2005 to January 2013, 43 patients with chronic locked anterior shoulder dislocation were treated surgically in our institution. Open Latarjet procedures were performed in 35 patients. A subscapularis tenotomy or split was chosen on the basis of the ability to achieve open reduction. Outcomes were assessed preoperatively and postoperatively with the American Shoulder and Elbow Surgeons (ASES) score, the visual analog scale (VAS) for pain, the University of California Los Angeles (UCLA) shoulder rating scale, and the Constant-Murley rating scale. A comparison of the clinical outcomes among the patients who underwent subscapularis tenotomy and repair, those who underwent a procedure that used the subscapularis-splitting technique, and those who underwent a concomitant humeral head replacement was performed. Twenty-five shoulders of 25 patients were available for a mean follow-up of 31.6 months. At the time of the latest follow-up, the range of motion and the shoulder functional evaluations (VAS [p = 0.02], ASES [p = 0.01], Constant score [p = 0.01], and UCLA score [p = 0.04]) were significantly improved. The overall redislocation or subluxation rate was 48% (12 of 25): 0% (0 of 5) for the subscapularis-splitting group, 53% (8 of 15) for the subscapularis tenotomy and repair group, and 80% (4 of 5) for the humeral head replacement group.

    To examine cases of intermediate uveitis complicated by retinoschisis and review the pathogenetic hypothesis. A retrospective chart review of patients with intermediate uveitis. Data were collected at three uveitis referral centers on sex, age, best-corrected visual acuity, degree of vitritis, extent and location of snowbanking, presence of hard exudates, neovascularization, vitreous hemorrhage, and extent and nature of retinal elevations. A series of 23 eyes of 20 patients were examined; patient's age ranged from 10 years to 70 years and follow-up period from 8 months to 6 years. Twenty-two eyes had retinoschisis (95.6%), and 1 had retinoschisis associated with serous retinal detachment (4.3%). Extensive inferior pars plana exudates with snowbanking were present in 12 eyes (52.2%), whereas 3 eyes had inferior snowballs over the elevated retina. Neovascularization of the vitreous base accompanied by vitreous hemorrhage occurred in one eye. There was no coexisting macular pathology in 16 eyes, whereas 4 eyes had cystoid macular edema. The appearance of peripheral retinoschisis in this series of uncontrolled intermediate uveitis patients seems to be secondary to a complex balance between the persistent fluorescein leakage, a subclinical peripheral ischemia, and the constant low-grade vitreous inflammation that causes vitreous shrinkage and traction. The results of this study suggest that the absence of macroscopic changes in the retina does not preclude ischemic peripheral abnormalities, and the detection of a peripheral retinoschisis in an intermediate uveitis patient with active fluorescein leakage must suggest the need for a more aggressive form of treatment despite the good visual acuity.

    We report on 22 patients with chronic grade-2 valgus laxity of the knee combined with chronic anterior cruciate ligament (ACL) insufficiency, in whom the two lesions were addressed at the same surgical setting. At a minimum follow-up of 24 months, clinical and functional variables had improved significantly (P < 0.001), and 20 of the 22 patients (91%) had returned to sport at pre-injury level. There were no operative complications in this series. In selected athletes with chronic symptomatic valgus laxity of the knee combined with ACL insufficiency, surgical repair of the MCL in association with ACL reconstruction is a suitable and reliable option to restore knee stability and allow return to pre-injury activity level.

    The purpose of the study was to identify the clinical and etiological profile of uveitis at the apex institute for eye care in India. This is a prospective, prevalence study. 980 consecutive patients with uveitis referred to uvea clinic, Dr. RP Centre for Ophthalmic Sciences (Ophthalmology division, All India Institute of Medical Sciences). Demographic data of each patient were noted and a thorough ocular examination including slit lamp examination and dilated fundus evaluation was carried out. OCT and fluorescein angiography were undertaken whenever indicated. Uveitis was classified based on the anatomic location of inflammation (IUSG classification). Relevant serological and radiological investigations were obtained based on systemic symptomatology, and if the uveitis was recurrent (even in the absence of systemic symptoms). The presence of a systemic disease was confirmed by obtaining an internist consultation. The main outcome measures include pattern of uveitis according to anatomical classification and the etiology. Out of 980 patients with uveitis, 413 (42.14 %) patients had anterior uveitis, 131 (13.36 %) had intermediate uveitis, 165 (16.83 %) had posterior uveitis, 91 (9.2 %) had panuveitis, 47 (4.7 %) had retinal vasculitis, 22 (2.24 %) had scleritis, 17 (1.7 %) had masquerade syndromes, 8 (0.8 %) had keratouveitis, 22 (2.24 %) had sclerokeratouveitis, 19 (1.9 %) had endophthalmitis and 45 (4.5 %) had other causes of inflammation including trauma and intraocular surgery. Out of all uveitic patients definite etiological correlation could be made out in 225 (23 %) patients; thus 77 % were categorised as idiopathic. Only 9 % of all patients were found to have uveitis with an infectious etiology. Amongst infectious causes of uveitis tuberculosis was the leading cause, accounting for sixty percent of all infectious uveitis (approximately 5 % of overall uveitis). Non-infectious uveitis etiology accounted for more than 90 % of all cases with

    Multiligamentous injury to the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) is an uncommon but debilitating event. Patients with combined ligament injuries typically complain of painful, debilitating knee instability that restricts their sports and daily activities. The purpose of this retrospective study was to evaluate functional and clinical outcomes of patients with chronic ACL and PCL deficiency who underwent simultaneous single-stage arthroscopic reconstruction of the central pivot. Medical records of 20 consecutive patients with chronic ACL and PCL deficiency who underwent simultaneous single-stage arthroscopic reconstruction of the central pivot were retrospectively reviewed. All patients had received either an allograft (group A) or a semitendinosus-gracilis graft for ACL repair and a bone-patellar tibial-bone graft for PCL repair (group B). Functional outcomes, after the initial follow-up period at 24-month FU, were assessed with concentric isokinetic knee extensor-flexor testing at 60 and 180°/s. The secondary aim was to compare long-term clinical recovery by the administration of the IKDC (International Knee Document Committee) Knee Ligament Evaluation Form, the Lysholm Knee Scoring Scale and the Cincinnati Knee Rating Scale. The mean per cent quadriceps strength deficit in the operated as compared to the healthy knee was 13.5 % in group A and 15 % in group B (angular velocity 60°/s) and 13.5 % in group A and 9.4 % in group B (angular velocity 180°/s). The mean per cent flexor strength deficit in the operated as compared to the healthy knee was 10.4 % in group A and 12.3 % in group B (angular velocity 60°/s) and 12.2 % in group A and 9 % in group B (angular velocity of 180°/s). The flexor-quadriceps ratio was 49.4 % in group A and 48.8 % in group B in the healthy knee and 53.2 % in group A and 53.8 % in group B in the operated knee (angular velocity 60°/s) and 63.9 % in group A and 60.7 % in group B in

    Background Chronic pain is a common cause of reduced quality of life. Recent studies suggest that chronic pain patients have a different brain neurometabolic status to healthy people. Proton magnetic resonance spectroscopy (1H-MRS) can determine the concentrations of metabolites in a specific region of the brain without being invasive. Patients and methods We recruited 56 chronic pain patients and 60 healthy controls to compare brain metabolic characteristics. The concentrations of glutamic acid (Glu), myo-inositol (Ins), N-acetylaspartate (NAA), Glu + glutamine (Glx), and creatine + phosphocreatine (total creatine [tCr]) in the anterior cingulate cortex of participants were measured using 1H-MRS. We used age- and gender-adjusted general linear models and receiver-operating characteristic analyses for this investigation. Patients were also assessed using the Hospital Anxiety and Depression Scale (HADS) to reveal the existence of any mental health issues. Results Our analysis indicates that pain patients have statistically significantly higher levels of Glu/tCr (p=0.039) and Glx/tCr (p<0.001) and lower levels of NAA/tCr than controls, although this did not reach statistical significance (p=0.052). Receiver-operating characteristic analysis performed on the combination of Glx/tCr, Ins/tCr, and NAA/tCr effectively discriminated chronic pain patients from healthy controls. Patients with higher HADS-Depression scores had increased Glx/rCr levels (p=0.015), and those with higher HADS-Anxiety scores had increased NAA/tCr levels (p=0.018). Conclusion Chronic pain patients have a different metabolite status in the anterior cingulate cortex to controls. Within the pain patient group, HADS scores had a positive relationship with NAA/tCr and Glx/tCr levels. 1H-MRS successfully detected metabolic changes in patients’ brains in a noninvasive manner, revealing its potential as a superior diagnostic tool for pain patients.

    Clinicians frequently diagnose chronic ankle instability using the manual anterior drawer test and stress radiography. However, both examinations can yield incorrect results and do not reveal the extent of ankle instability. Stress ultrasound has been reported to be a new diagnostic tool for the diagnosis of chronic ankle instability. The purpose of this study was to assess the diagnostic value of stress ultrasound for chronic ankle instability compared to the manual anterior drawer test, stress radiography, magnetic resonance imaging (MRI), and arthroscopy. Twenty-eight consecutive patients who underwent ankle arthroscopy and subsequent modified Broström repair for treatment of chronic ankle instability were included. The arthroscopic findings were used as the reference standard. A standardized physical examination (manual anterior drawer test), stress radiography, MRI, and stress ultrasound were performed to assess the anterior talofibular ligament (ATFL) prior to operation. Ultrasound images were taken in the resting position and the maximal anterior drawer position. Grade 3 lateral instability was verified arthroscopically in all 28 cases with a clinical diagnosis (100%). Twenty-two cases showed grade III instability on the manual anterior drawer test (78.6%). Twenty-four cases displayed anterior translation exceeding 5 mm on stress radiography (86%), and talar tilt angle exceeded 15° in three cases (11 %). Nineteen cases displayed a partial chronic tear (change in thickness or signal intensity), and nine cases displayed complete tear on MRI (100%). Lax and wavy ATFL was evident on stress ultrasound in all cases (100 %). The mean value of the ATFL length was 2.8 ± 0.3 cm for the stressed condition and 2.1 ± 0.2 cm for the resting condition (p < 0.001). Stress ultrasound may be useful for the diagnosis of chronic ankle instability in addition to the manual anterior drawer test and stress radiography. III.

    The study aimed to describe the effectiveness of switching the anti-TNFα agent when an acceptable clinical response has not been obtained with the first anti-TNFα agent in patients with uveitis in VKH syndrome. Patients diagnosed with VKH syndrome being evaluated from the uveitis unit of a single tertiary hospital from January 1, 2000, to October 30, 2015. Patients who presented uveitis with an inadequate response to a first anti-TNFα and required switching to a second anti-TNFα were selected. Complete clinical response was assumed in patients whose visual acuity was normal and those who showed absence of inflammatory findings (inflammatory cells in the anterior chamber and vitritis) or absence of macular thickening in upon OCT. A systematic review of the literature of anti-TNFα agents in VKH syndrome was performed. Five patients met the criteria of VKH syndrome. Two cases of VKH syndrome with uveitis and inadequate clinical response to an initial anti-TNFα (both IFX) were presented. After switching to Adalimumab (ADA), a satisfactory clinical response was noted in the first month. For the first time, we present two patients with severe uveitis due to VKH syndrome who after inadequately responding to the first anti-TNFα agent showed complete and maintained clinical improvement when switched to a second anti-TNFα agent.

    Uveitis in the equine population of the UK does not appear to be as prevalent or disastrous as seen across regions of Europe and the USA. Some cases perceived to be recurrent uveitis may be poorly resolved single episodes of uveitis and care should be taken not to make the diagnosis of recurrence without ensuring effective control of the initial episode. Leptospira spp. appear to play only a minor role ERU in the UK which is probably the main reason for the prevalence of the disease being much lower compared to the USA and mainland Europe. Actual data are relatively few on the ground as far as disease surveillance in concerned. This has 2 implications. Firstly unless we are able to effectively monitor the levels of uveitic disease, it will be difficult to pick up early changes in the trend which may allow quicker intervention. Secondly, it is difficult to secure funding for further research if the prevalence of the problem is poorly defined. This may leave the UK equine population at risk should the disease profile suddenly alter for the worse.

    The identification of an infectious or noninfectious uveitis syndrome is important to determine the range of therapeutic and prognostic implications of that disease entity. Diagnostic dilemmas arise with atypical history, atypical clinical presentations, inconclusive diagnostic workup, and persistent or worsened inflammation despite appropriate immunosuppression. More invasive intraocular testing is indicated in these situations particularly in infectious uveitis where a delay in treatment may result in worsening of the patient’s disease and a poor visual outcome. Laboratory analysis of vitreous fluid via diagnostic pars plana vitrectomy is an important technique in the diagnostic armamentarium, but the most important aspects of sample collection include rapid processing, close coordination with an ophthalmic pathology laboratory, and directed testing on this limited collected sample. Culture and staining has utility in bacterial, fungal, and nocardial infection. Polymerase chain reaction (PCR) analysis has shown promising results for bacterial endophthalmitis and infection with mycobacterium tuberculosis whereas PCR testing for viral retinitides and ocular toxoplasmosis has a more established role. Antibody testing is appropriate for toxoplasmosis and toxocariasis, and may be complementary to PCR for viral retinitis. Masquerade syndromes represent neoplastic conditions that clinically appear as infectious or inflammatory conditions and should be considered as part of the differential diagnosis. Diagnostic vitrectomy and chorioretinal biopsy are thus critical tools for the management of patients in whom an infectious etiology of uveitis is suspected. PMID:24613892

    Emergent and resurgent arthropod vector-borne diseases are major causes of systemic morbidity and death and expanding worldwide. Among them, viral and bacterial agents including West Nile virus, Dengue fever, Chikungunya, Rift Valley fever, and rickettsioses have been recently associated with an array of ocular manifestations. These include anterior uveitis, retinitis, chorioretinitis, retinal vasculitis and optic nerve involvement. Proper clinical diagnosis of any of these infectious diseases is based on epidemiological data, history, systemic symptoms and signs, and the pattern of ocular involvement. The diagnosis is usually confirmed by the detection of a specific antibody in serum. Ocular involvement associated with emergent infections usually has a self-limited course, but it can result in persistent visual impairment. There is currently no proven specific treatment for arboviral diseases, and therapy is mostly supportive. Vaccination for humans against these viruses is still in the research phase. Doxycycline is the treatment of choice for rickettsial diseases. Prevention, including public measures to reduce the number of mosquitoes and personal protection, remains the mainstay for arthropod vector disease control. Influenza A (H1N1) virus was responsible for a pandemic human influenza in 2009, and was recently associated with various posterior segment changes.

    Uveitis represents the inflammatory process of uvea being caused by an autoimmune mechanism. Similarly, systemic connective tissue diseases (CTDs) present as well an autoimmune pathogenesis and numerous are the reports of a correlated association of the two different conditions, according to their serological characteristics. In this work, we have studied a number of subjects affected by uveitis as well as a number of subjects affected by CTDs associated with uveitis (14.2%). Only one significant correlation has been observed here, and it is the one between uveitis and the Systemic Lupus Erythematosus (SLE, 42.8%). The observation has been made up to through a time-lapse of 18 months during which, the signs of uveitis showed a clear trend to faintly diminish till completely disappearing. At the same time, the presence of uveitis has not stressed out any correlation either with the general positivity for the autoantibodies, nor with the titration or the pattern of single fluorescent antibodies. This study seems to confirm the presence of a weak association between uveitis and CTDs (SLE excluded), where the research of antinuclear antibodies does not seem to give any useful element in terms of diagnostics and clinics, able to value the risk of developing CTDs when uveitis is already stated.

    To investigate the incidence and risk factors of secondary glaucoma among uveitis patients. Retrospective review of medical records of 642 patients (1220 eyes). Glaucoma was diagnosed in 169 (13.9%) eyes and was most common in eyes with anterior uveitis (19.1%) (p < 0.001). HLA-B27-positive anterior uveitis (27.6%), Fuchs' uveitis (23.3%), juvenile idiopathic arthritis (23.1%), herpetic uveitis (20.3%), and Vogt-Koyanagi-Harada disease (16.3%) were the leading clinical entities associated with glaucoma (p < 0.001). Significant risk factors at presentation included worse visual acuity, elevated intraocular pressure, keratic precipitates, granulomatous inflammation, anterior chamber reaction≥ 2+, posterior synechiae, and cataract. Female gender and iris nodules significantly predicted the need for glaucoma surgery. Visual outcome was worse in eyes with glaucoma than in eyes without glaucoma. Incidence of glaucoma differed depending on anatomic and etiologic diagnoses of uveitis. There is a significant association between severity of inflammation at presentation and development of glaucoma.

    In this case report we describe for the first time an association between autoimmune hepatitis (AIH) and uveitis, without any doubts about other possible etiologies, such as HCV, since all the old reports describe the association of AIH with iridocyclitis before tests for HCV-related hepatitis could be available. A 38-year-old businessman with abnormal liver function tests and hyperemia of the bulbar conjunctiva was admitted to the hospital. Six years before admission, the patient presented with persistent fever, arthralgias, conjunctival hyperemia, leukocytosis and increased ESR, referred to acute rheumatic fever. The presence of systemic diseases, most commonly associated with uveitis, was investigated without results and the patient was then treated with topical corticosteroids. His symptoms resolved. A test for anti-nuclear antibodies was positive, at a titre of 1:320, with a speckled and nucleolar staining pattern. Liver ultrasound showed mild hepatomegaly with an increased echostructure of the liver. Percutaneous liver biopsy was performed under ultrasound assistance. Histological examination showed necroinflammation over the portal, periportal and lobular areas, fibrotic portal tracts, with periportal fibrosis and occasional portal-to-portal bridgings, but intact hepatic architecture. Some hepatocytes showed barely discernible granules of hemosiderin in the lobular area. Bile ductules had not any significant morphological alterations. METAVIR score was A2-F3, according to the modified HAI grading/fibrosis staging. The patient was diagnosed to have AIH with mild activity and fibrosis and was discharged on 25 mg prednisone, entering clinical and biochemical remission, further confirming diagnosis. After discharge the patient continued to have treatment with corticosteroids as an outpatient at a dose of 5 mg. On January 2002 the patient was readmitted to the hospital.

    Antero-medial instability of the knee comprises 96 p. 100 of all knee instabilities. In most instances, the instability is moderate and cannot be analyzed without an adequate understanding of the anatomy and mechanics of the joint. They usually occur after forced movement in medial rotation which ruptures the anterior cruciate ligament and may rupture the postero-medial ligament. Less frequently, they appear after a strain in abduction, flexion and lateral rotation. Some degree of hyper-extension may be added to the primary causal strain. Diagnosis is mainly based on the physical examination which determines the type of surgical procedure that should be made. An anterior draw sign and a click in medial rotation are present when the anterior cruciate ligament is torn. When these signs are very marked, it implies an associated tear of the postero-medial ligament. Standard X-rays and arthrography are most important. Arthroscopy is not of great value and only makes it possible to visualize the meniscus lesions which are important for prognosis. The author describes an original concept of the mechanics of rotation of the knee and the pathogenesis of lesions of the medial capsulo-ligamentous layer.

    Objective The Effects of Youngsters’ Eyesight on Quality of Life (EYE-Q) is a novel measure of vision-related quality of life (QOL) and function in children. We aim to determine the validity of EYE-Q in childhood uveitis. Methods We abstracted medical record data on arthritis and uveitis in a convenience sample of children with juvenile idiopathic arthritis (JIA) and/or uveitis. In addition to the EYE-Q, parents and patients completed questionnaires on overall QOL (Pediatric QOL Inventory - PedsQL), and physical functioning (Childhood Health Assessment Questionnaire - CHAQ). Results Among 57 children (8 JIA, 24 JIA and uveitis, 25 uveitis alone), 102 ocular examinations were performed within 1 month of completing questionnaires. Uveitis patients had bilateral disease (69%), anterior involvement (78%), synechiae (51%) and cataracts (49%). Children with vision loss in their better eye (visual acuity (VA) 20/50 or worse) had worse EYE-Q (p = 0.006), and PedsQL (p = 0.028), but not CHAQ scores. The EYE-Q moderately correlated with logMAR VA (rs = −0.43), PedsQL (rs = 0.43) and CHAQ (rs = −0.45), but was not correlated with anterior chamber cells or intraocular pressure. The PedsQL and CHAQ did not correlate with VA or cells. There were strong correlations between the parent and child EYE-Q (rs = 0.62). Cronbach's α for the child report was 0.91. The EYE-Q had strong test-retest reliability (rs=0.75). Conclusion The EYE-Q may be an important tool in the assessment of visual outcomes in childhood uveitis and an improvement over general measures in detecting changes in vision-related function.

    The healing of periodontal splinting can be detected both with clinical and radiographic examination. In this study, the alveolar bone was evaluated by radiographic digital periapical analysis. Periodontal tooth splinting is periodontal support therapy used to prevent periodontal injury during repair and regeneration of periodontal therapy. Radiographic digital periapical analysis of alveolar bone in the mandibular anterior region with chronic periodontitis and 2/3 cervical bone loss after three months of periodontal splinting. Eighty four proximal site (43 mesial and 41 distal) from 16 patients with chronic periodontitis and treated with spinting were examined by taking periapical digital radiographic at day 1 and 91. The bone loss, bone density and utility of lamina dura were evaluated. The statistical analysis after three months evaluation using T-test for bone loss, Wilcoxon sign rank test for bone density and utility lamina dura showed no significantly differences (p<0.05) (p=0.44, 0.256 and 0.059). No radiographic change in bone loss, bone density and utility of lamina dura from chronic periodontitis with 2/3 alveolar bone loss after three months splinting.

    To evaluate the risk of and risk factors for retinal neovascularization (NV) in cases of uveitis. Retrospective cohort study. Patients with uveitis at 4 US academic ocular inflammation subspecialty practices. Data were ascertained by standardized chart review. Prevalence data analysis used logistic regression. Incidence data analysis used survival analysis with time-updated covariates where appropriate. Prevalence and incidence of NV. Among uveitic eyes of 8931 patients presenting for initial evaluation, 106 of 13,810 eyes had NV (prevalence = 0.77%, 95% confidence interval [CI], 0.60-0.90). Eighty-eight more eyes developed NV over 26,465 eye-years (incidence, 0.33%/eye-year; 95% CI, 0.27-0.41). Factors associated with incident NV include age <35 years compared with >35 years (adjusted hazard ratio [aHR], 2.4; 95% CI, 1.5-3.9), current cigarette smoking (aHR, 1.9; 95% CI, 1.1-3.4), and systemic lupus erythematosus (aHR, 3.5, 95% CI, 1.1-11). Recent diagnosis of uveitis was associated with an increased incidence of NV (compared with patients diagnosed >5 years ago, aHR, 2.4 [95% CI, 1.1-5.0] and aHR, 2.6 [95% CI, 1.2-6.0] for diagnosis within <1 year vs. 1-5 years, respectively). Compared with anterior uveitis, intermediate uveitis (aHR, 3.1; 95% CI, 1.5-6.6), posterior uveitis (aHR, 5.2; 95% CI, 2.5-11), and panuveitis (aHR, 4.3; 95% CI, 2.0-9.3) were associated with a similar degree of increased NV incidence. Active (aHR, 2.1, 95% CI, 1.2-3.7) and slightly active (aHR, 2.4, 95% CI, 1.3-4.4) inflammation were associated with an increased incidence of NV compared with inactive inflammation. Neovascularization incidence also was increased with retinal vascular occlusions (aHR, 10, 95% CI, 3.0-33), retinal vascular sheathing (aHR, 2.6, 95% CI, 1.4-4.9), and exudative retinal detachment (aHR, 4.1, 95% CI, 1.3-13).

    Ocular brucellosis is usually diagnosed by clinical criteria and serological tests. Little is known with regard to the ocular immunology of brucellosis and the use of intraocular diagnostic tests. We report retrospectively the laboratory findings of patients with ocular involvement associated with brucellosis. Patients with uveitis with no evident etiologic diagnosis were evaluated at the Instituto de Medicina Tropical "Alexander von Humboldt" of the Universidad Peruana Cayetano Heredia and the Hospital Nacional Cayetano Heredia. Patients were tested for brucellosis, tuberculosis, syphilis, toxoplasmosis, toxocariasis, and human T-cell lymphotropic virus-1. Blood and intraocular fluid samples were examined. Patients with a diagnosis of brucellar uveitis were selected as cases and patients with a diagnosis of uveitis of other etiology were included as controls. The Goldmann-Witmer coefficient was determined. Twelve patients with clinical and laboratory findings suggestive of brucellar uveitis were considered as cases. Seven patients with uveitis of other etiology were selected as controls. Four (33.3%) patients with ocular brucellosis had negative ocular agglutinations and eight (66.7%) had positive agglutinations. No control cases had positive agglutinations for Brucella melitensis. The sensitivity of the test was 66.7% and the specificity 100%. Only one patient had a positive culture for B. melitensis in subretinal fluid. The Goldmann-Witmer coefficient was calculated in six cases of brucellosis uveitis and five uveitis controls. It was highly positive in three patients with ocular brucellosis. Tissue samples showed lymphoplasmacytic infiltrates. Intraocular serological tests could be used to support the diagnosis of ocular brucellosis.

    Retrospective case series, database study and literature review. Forty case reports are described. To report a possible association between fluoroquinolones and uveitis. Spontaneous reports from the National Registry of Drug-Induced Ocular Side effects, World Health Organization, and Food and Drug Administration were collected on uveitis associated with systemic fluoroquinolone therapy. A literature review was performed using keywords "uveitis", "fluoroquinolones", and each individual fluoroquinolone name. Additional case reports were collected from the practices of six uveitis subspecialists and one neuro-ophthalmologist. Data garnered from the reports include the type of fluoroquinolone, age, gender, adverse drug reaction (ADR), dosage, duration of therapy until onset of uveitis, concomitant drugs, systemic disease, dechallenge and rechallenge data. A total of 40 case reports of uveitis associated with fluoroquinolones were identified including 12 men, 27 women, and 1 case in which the gender was not specified. The median age was 54 years. Dosage varied between the different fluoroquinolone drugs, with the median dosage within the range recommended in the package insert for each different fluoroquinolone. Median time from beginning of therapy to appearance of the ADR was 13 days (range 0-20 days). Thirteen patients were 60 years or older, and one patient was taking systemic anti-inflammatory steroids. There were five positive dechallenge case reports. According to World Health Organization criteria, the relationship between fluoroquinolone therapy and uveitis is "possible". Causality assessments are based on the time relationship of drug administration, uveitis development, and dechallenge data. Clinicians should be aware of a possible bilateral fluoroquinolone-associated uveitis, particularly the finding of iris transillumination and pigment dispersion.

    Shoulder dislocation is frequently encountered by orthopedists, and closed manipulation is often sufficient to treat the injury in an acute setting. Although most dislocations are diagnosed and managed promptly, there are rare cases that are missed or neglected, leading to a chronically dislocated state of the joint. They are usually irreducible and cause considerable pain and functional disability in most affected patients, prompting the need to find a surgical method to reverse the worsening conditions caused by the dislocated joint. However, there are cases of even greater rarity in which chronic shoulder dislocations are asymptomatic with minimal functional or structural degeneration in the joint. These patients are usually left untreated, and most show good tolerance to their condition without developing disabling symptoms or significant functional loss over time. We report on one such patient who had a chronic shoulder dislocation for more than 2 years without receiving treatment.

    Uveitis models in rodents are important in the investigation of pathogenesis in human uveitis and the development of appropriate therapeutic strategies for treatment. Quantitative monitoring of ocular inflammation in small animal models provides an objective metric to assess uveitis progression and/or therapeutic effects. We present a new application of optical coherence tomography (OCT) and OCT-based microangiography (OMAG) to a rat model of acute anterior uveitis induced by intravitreal injection of a killed mycobacterial extract. OCT/OMAG is used to provide noninvasive three-dimensional imaging of the anterior segment of the eyes prior to injection (baseline) and two days post-injection (peak inflammation) in rats with and without steroid treatments. OCT imaging identifies characteristic structural and vascular changes in the anterior segment of the inflamed animals when compared to baseline images. Characteristics of inflammation identified include anterior chamber cells, corneal edema, pupillary membranes, and iris vasodilation. In contrast, no significant difference from the control is observed for the steroid-treated eye. These findings are compared with the histology assessment of the same eyes. In addition, quantitative measurements of central corneal thickness and iris vessel diameter are determined. This pilot study demonstrates that OCT-based microangiography promises to be a useful tool for the assessment and management of uveitis in vivo.

    The rotator cuff musculature imparts dynamic stability to the glenohumeral joint. In particular, the balance between the subscapularis anteriorly and the infraspinatus posteriorly, often referred to as the rotator cuff "force couple," is critical for concavity compression and concentric rotation of the humeral head. Restoration of this anterior-posterior force balance after chronic, massive rotator cuff tears may allow for deltoid compensation, but no in vivo studies have quantitatively demonstrated an improvement in shoulder function. Our goal was to determine if restoring this balance of forces improves shoulder function after two-tendon rotator cuff tears in a rat model. Forty-eight rats underwent detachment of the supraspinatus and infraspinatus. After four weeks, rats were randomly assigned to three groups: no repair, infraspinatus repair, and two-tendon repair. Quantitative ambulatory measures including medial/lateral forces, braking, propulsion, and step width were significantly different between the infraspinatus and no repair group and similar between the infraspinatus and two-tendon repair groups at almost all time points. These results suggest that repairing the infraspinatus back to its insertion site without repair of the supraspinatus can improve shoulder function to a level similar to repairing both the infraspinatus and supraspinatus tendons. Clinically, a partial repair of the posterior cuff after a two-tendon tear may be sufficient to restore adequate function. An in vivo model system for two-tendon repair of massive rotator cuff tears is presented. Copyright © 2011 Orthopaedic Research Society.

    Uveitis can lead to vision loss and blindness in children. It can significantly impact a child’s vision related quality of life and daily function. Outcome studies in pediatric uveitis focus on the clinical ocular exam and general measures of quality of life whereas in adults, measures of visual function are incorporated. Adequate vision can affect a child’s daily activities and is crucial for daily function in the home and school. A comprehensive approach that incorporates all aspects of disability could improve the assessment of outcomes and may help us better understand the impact of visual impairment on children with uveitis.

    The course of disease in a 64-year-old man with toxocariasis and ocular manifestations of the disease, treated at Departments of Ophthalmology and of Infectious Diseases, Dr. Josip Bencević General Hospital in Slavonski Brod, Croatia, is presented. The patient was hospitalized for bilateral uveitis of unknown etiology. In several days, the patient developed high fever with respiratory tract involvement and hepatomegaly. Worsening of the patient's general condition and laboratory findings of leukocytosis and eosinophilia indicated clinical examinations for parasitosis, in consultation with a specialist for infectious diseases. Specific serologic testing pointed to toxocariasis. The patient's general condition and ophthalmologic status improved in response to specific therapy with anthelmintics and corticosteorids. Toxocariasis is an acute infectious disease that primarily affects animals and less frequently humans. Clinically, toxocariasis manifests as a systemic disease, and on the eye as parasitic posterior uveitis. The disease is caused by the nematodes Toxocara canis and Toxocara cati, the species parasitic in the intestine of dogs and cats, respectively. When the parasite eggs reach human intestine, larvae are released and migrate via blood and lymphatic system to the liver, lungs, eyes, and other organs. Considering the mechanism of disease transmission, the potential preventive measures should include treatment and appropriate anthelmintic management of infected animals, and due control of public areas such as public gardens, promenades, playgrounds, along with taking pets for exercise to the sites specially intended for this purpose.

    To develop a disease activity index for patients with uveitis (UVEDAI) encompassing the relevant domains of disease activity considered important among experts in this field. The steps for designing UVEDAI were: (a) Defining the construct and establishing the domains through a formal judgment of experts, (b) A two-round Delphi study with a panel of 15 experts to determine the relevant items, (c) Selection of items: A logistic regression model was developed that set ocular inflammatory activity as the dependent variable. The construct "uveitis inflammatory activity" was defined as any intraocular inflammation that included external structures (cornea) in addition to uvea. Seven domains and 15 items were identified: best-corrected visual acuity, inflammation of the anterior chamber (anterior chamber cells, hypopyon, the presence of fibrin, active posterior keratic precipitates and iris nodules), intraocular pressure, inflammation of the vitreous cavity (vitreous haze, snowballs and snowbanks), central macular edema, inflammation of the posterior pole (the presence and number of choroidal/retinal lesions, vascular inflammation and papillitis), and global assessment from both (patient and physician). From all the variables studied in the multivariate model, anterior chamber cell grade, vitreous haze, central macular edema, inflammatory vessel sheathing, papillitis, choroidal/retinal lesions and patient evaluation were included in UVEDAI. UVEDAI is an index designed to assess the global ocular inflammatory activity in patients with uveitis. It might prove worthwhile to motorize the activity of this extraarticular manifestation of some rheumatic diseases.

    A study was performed on the effect of the addition of an extra-articular procedure involving tenodesis of the iliotibial band to a reconstruction with a bone-patellar ligament-bone allograft for the treatment of chronic rupture of the anterior cruciate ligament. One hundred and four patients were divided into two groups for comparison: Group 1 (sixty-four patients) was treated with only an intra-articular replacement with an allograft and Group 2 (forty patients), with both an intra-articular replacement with an allograft and the extra-articular procedure. Preoperatively, there were no statistically significant differences between the two groups in terms of twenty variables, including body weight, level of activity, anterior-posterior displacements, number of previous operations, and duration of follow-up. All of the patients returned for follow-up evaluation twenty-three to fifty-four months (mean, thirty-five months) postoperatively. All were treated with the same postoperative program of immediate motion of the knee and rehabilitation. The results were evaluated with the use of a comprehensive subjective and objective system that rated the twenty factors. Both procedures proved to be effective in decreasing functional limitations and symptoms and in improving the level of sports activity and the over-all scores. The results in Group 2 were significantly better than those in Group 1, as measured with tests done with the KT-1000 arthrometer (p less than 0.01) and with regard to the level of sports activity (p less than 0.05) and the over-all scores (p less than 0.01). There was no postoperative difference between the two groups in terms of the results on pivot-shift or isokinetic testing, patellofemoral crepitus, functional limitations, or symptoms. The program of rehabilitation effectively restored 0 to 135 degrees of motion to all but four knees, which lacked 5 degrees of extension at the most recent follow-up. The over-all rate of failure for both groups was

    A total of 250 patients was reviewed 71.8 months (range 49-105 months) after anterior cruciate ligament (ACL) reconstruction for disabling instability that had not responded to conservative treatment or correction of internal derangements. Knees that had undergone previous operation or had damage to other ligaments were excluded. Four techniques were used; MacIntosh extra-articular lateral substitution alone (n = 18), extra-articular reconstruction plus intra-articular carbon fibre (n = 29), extra-articular reconstruction plus a free graft from the medial third of the patellar tendon (n = 74), or extra-articular reconstruction plus a Leeds-Keio prosthesis (n = 129). The knees were assessed 1, 3 and 6 years after reconstruction using the Lysholm score and clinical examination for the anterior drawer, Lachman and pivot shift signs. The mean Lysholm score after 6 years was 77.4 (range 31-100) in the extra-articular group; 74.4 (range 34-100) in the carbon fibre group; 95.4 (range 43-100) in the patellar tendon group; and 91.2 (range 45-100) in the Leeds-Keio group. The patellar tendon group had the highest scores (P < 0.003). The pivot shift sign returned in 39% of the extra-articular group; 48% of the carbon fibre group; 1% of the patellar tendon group, and 36% of the Leeds-Keio group. The pivot shift returned least often in the patellar tendon group (P < 0.001). There were 44% satisfactory results (pivot shift negative and Lysholm score 77 or more) in the extra-articular group; 55% in the carbon fibre group; 92% in the patellar tendon group; and 60% in the Leeds-Keio group.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7574323

    Abstract Background: Uveitis is the most common extra-articular manifestation in patients with ankylosing spondylitis (AS). The prevalence and characteristics of uveitis in AS have been studied in previous literatures, whereas its associated risk factors have not been clarified. Therefore, this study analyzed the risk factors of uveitis in patients with AS. Methods: A total of 390 patients with AS who fulfilled the modified New York criteria were enrolled from January to December in 2015. The history of uveitis was accepted only if diagnosed by ophthalmologists. The medical records of the patients were retrospectively reviewed and associated information was collected, such as disease duration, HLA-B27, and the number of peripheral arthritis. Hip-joint lesion was identified by imaging examination. Meanwhile, biochemical examinations were performed to determine the patient's physical function. Results: Of 390 patients with AS (80.5% male, mean age 33.3 years), 38 (9.7%) had experienced 1 or more episodes of uveitis. The incidence rate for hip-joint lesion was obviously higher for patients with uveitis than the nonuveitis group (44.7% vs 22.2%; P < 0.01). The number of peripheral arthritis was also larger for the uveitis group than nonuveitis group (2.18 ± 0.23 vs 0.55 ± 0.04; P < 0.001). Meanwhile, patients with uveitis had a significantly higher level of antistreptolysin O (ASO) and circulating immune complex (CIC) than those without (P < 0.05 and P < 0.0001, respectively). However, there were no significant differences in disease duration, HLA-B27, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) between the 2 groups. Binary logistic regression results showed that ASO (OR = 12.2, 95% CI:3.6–41.3, P < 0.01) and the number of peripheral arthritis (OR = 4.1, 95%CI:2.6–6.3, P < 0.01) are significantly associated with uveitis in AS. Conclustion: This study provides some evidence that hip-joint lesion, the number of

    Fluoroquinolones are the most commonly prescribed antibiotic class in the outpatient setting. Recent reports have implicated an association between oral fluoroquinolones and an increased risk of uveitis. To determine the hazard of uveitis with oral fluoroquinolone use. A retrospective cohort study was conducted using medical claims data from a large national US insurer (N = 4,387,651). Cohorts from ambulatory care centers across the United States were created including every new user of an oral fluoroquinolone or β-lactam antibiotic prescription with at least 24 months of data prior to the date of the prescription from January 1, 2000, to January 30, 2013. Exclusion criteria consisted of any previous diagnosis of uveitis or a uveitis-associated systemic illness. Participants were censored for a new diagnosis of a uveitis-associated systemic illness, the end of an observation period, use of the other class of antibiotic, or removal from the insurance plan. Data analysis was performed from January 2 through March 15, 2015. The hazard of a uveitis diagnosis after a fluoroquinolone prescription compared with a β-lactam prescription using multivariate regression with Cox proportional hazards models. Of the 4,387,651 patients in the database, 843,854 individuals receiving a fluoroquinolone and 3,543,797 patients receiving a β-lactam were included in the analysis. After controlling for age, race, and sex using multivariate analysis, no hazard for developing uveitis at the 30-, 60-, or 90-day observation windows was seen (hazard ratio [HR] range, 0.96; 95% CI, 0.82-1.13; to 1.05; 95% CI, 0.95-1.16; P > .38 for all comparisons). The 365-day observation period showed a small increase in the HR for the fluoroquinolone cohort (1.11; 95% CI, 1.05-1.17; P < .001). Moxifloxacin produced an increased hazard for uveitis at every time point (HR range, 1.47-1.75; 95% CI, 1.27-2.37; P < .001 for all comparisons). Secondary analysis demonstrated a similar hazard at 365 days for a

Bone area, BMD, BMC, lean mass and fat mass of lower extremity were measured using dual energy X-ray absorptiometry. The isometric and isokinetic muscle strength was assessed by an isokinetic machine.BMC, lean mass, circumference of the thigh and circumference of the lower leg of the injured lower extremity were significantly smaller than those of the intact lower extremity (p=0.0002, p<0.0001, p<0.0001, p=0.0131). In contrast, fat mass and %Fat of the injured lower extremity was significantly greater than that of the intact lower extremity (p=0.0301, p<0.0001). Bone area and BMD did not produce significant difference. These findings suggest that chronic insufficiency of ACL decreases BMC and lean mass of the injured lower extremity.

    Therapy for autoimmune ophthalmic disease is currently evolving. The improved understanding of the abnormal immune response in the various forms of uveitis has resulted in targeted therapy. The aberrations of the immune system have been characterized by atypical cell populations, cytokine expression, and cell-cell interactions. Different patterns of cytokine expression have now been delineated in the abnormal uveal tract with exaggerated and/or abnormal expression of TNF, IL-1, IL-2, IL-6, and IL-17. The development of therapies for other conditions in which these cytokines play an important role has resulted in the availability of biological agents that have been adopted for use in the therapy for uveitis. Adalimumab and infliximab have been the best studied anti-TNF agents and indeed have now been recommended by an expert panel as first-line treatment of ocular manifestations of Behçet's disease and second-line treatment for other forms of uveitis (Levy-Clarke et al. (Ophthalmology, 2013). Other anti-TNF agents have been studied as well. Daclizumab, a monoclonal antibody directed against the IL-2 receptor, has also demonstrated utility in treating uveitis as have some of the anti-IL1 agents. Gevokizumab has been granted orphan drug designation for the treatment of resistant forms of uveitis. Therapies affecting IL-6, including tocilizumab are being studied, and available medications that block antigen presenting cell and T cell interaction such as abatacept have been reported to be effective in uveitis. Interferons as well as rituximab have also been evaluated in small studies. Although these biologic therapies have provided a larger armamentarium to treat uveitis, challenges remain. Uveitis is not a single illness; rather, it is a manifestation of many potential systemic diseases that may have very specific individual therapeutic targets. Identifying and characterizing these underlying diseases is not always achieved, and more importantly, the most effective

    Radiographic features of lumbar disc degeneration (LDD) are common findings in patients with chronic mechanical low back pain; however, its role in disability and intensity of pain is debatable. This study aims to investigate the associations of the x-ray features of LDD and lumbar spondylolisthesis with severity of disability and intensity of pain. A cross-sectional study was conducted on 439 patients with chronic mechanical low back pain who attended the rheumatology clinic, National Hospital of Sri Lanka, Colombo, from May 2012 to May 2014. Severity of disability was measured using Modified Oswestry Disability Index and intensity of pain was assessed using numeric rating scale (0-100). X-ray features of LDD (disc space narrowing, anterior osteophytes and overall LDD) and spondylolisthesis were assessed in lateral recumbent lumbar x-rays (L1/L2 to L5/S1) and graded by a consultant radiologist blinded to clinical data. Generalised linear model with linear response was used to assess the associations of x-ray features of LDD with severity of disability and intensity of pain adjusting for age, gender, body mass index and pain radiating into legs. Mean age was 48.99 ± 11.21 and 323 (73.58%) were females. 87 (19.82%) were obese. Mean severity of disability was 30.95 ± 13.67 and mean intensity of pain was 45.50 ± 20.37. 69 (15.72%), 26 (5.92%) and 85 (19.36%) patients had grade 2 disc space narrowing, anterior osteophytes and overall LDD, respectively. 51 (11.62%) patients had lumbar spondylolisthesis. Grade of disc space narrowing and overall LDD were not associated with severity of disability or intensity of pain. The presence of lumbar spondylolisthesis was associated with severity of disability. Female gender and pain radiating into legs were associated with severity of disability and intensity of pain. Advancing age was associated with x-ray features of LDD and lumbar spondylolisthesis. Lumbar spondylolisthesis is associated with severity of

    Patient: Female, 32 Final Diagnosis: Nephrogenic diabetes inspidus secondary to tubulointerstitial nephritis and uveitis (TINU) syndrome Symptoms: — Medication: — Clinical Procedure: Kidney biopsy Specialty: Nephrology Objective: Rare disease Background: Tubulointerstitial nephritis and uveitis syndrome (TINU syndrome) is a diagnosis of exclusion based on the presence of uveitis and acute tubulointerstitial nephritis in the absence of other disease entities known to cause both of these disorders. The proximal tubule is frequently affected by this syndrome, resulting in a wide range of presentations that vary from proteinuria to full picture of Fanconi syndrome. However, distal tubular involvement is not common. Case Report: A 32-year-old female patient presented with polyuria, polydipsia and painful red eyes. Her water deprivation test and desmopressin test results were consistent with nephrogenic diabetes insipidus. Her kidney biopsy showed acute tubulointerstitial nephritis. Her eye exam was consistent with uveitis. To our knowledge, this is the first reported case of nephrogenic diabetes insipidus due to tubulointerstitial nephritis and uveitis syndrome. Conclusions: Tubulointerstitial nephritis and uveitis syndrome (TINU) syndrome can present with multiple renal tubular defects, including nephrogenic diabetes insipidus. PMID:25433171

    Purpose To evaluate the benefits and complications of periocular depot corticosteroid injections in patients with ocular inflammatory disorders. Design Multicenter retrospective cohort study. Participants A total of 914 patients (1192 eyes) who had received at least one periocular corticosteroid injection at 5 tertiary uveitis clinics in the United States. Methods Patients were identified from the Systemic Immunosuppressive Therapy for Eye Diseases (SITE) Cohort Study. Demographic and clinical characteristics were obtained at every visit via medical record review by trained reviewers. Main Outcome Measures Control of inflammation, improvement of visual acuity to 20/40 or better, improvement of visual acuity loss attributed to macular edema, incident cataract affecting visual acuity, cataract surgery, ocular hypertension and glaucoma surgery. Results Among 914 patients (1192 eyes) who received at least one periocular injection during follow-up, 286 (31.3%) were classified as having anterior uveitis, 303 (33.3%) as intermediate uveitis, 324 (35.4%) as posterior or panuveitis. Cumulatively by ≤6 months, 72.7% [95% confidence interval (95%CI): 69.1-76.3] of the eyes achieved complete control of inflammation and 49.7% [95%CI:45.5-54.1] showed an improvement in visual acuity (VA) from worse than 20/40 to 20/40 or better. Among the subset with VA worse than 20/40 attributed to macular edema, 33.1% [95%CI: 25.2-42.7] improved to 20/40 or better. By 12 months, the cumulative incidence of one or more visits with an intraocular pressure≥24 mmHg and ≥30 mmHg was 34.0% [95%CI: 24.8-45.4] and 15.0% [95%CI: 11.8-19.1] respectively; glaucoma surgery was performed in 2.4% [95%CI: 1.4-3.9] of eyes. Within 12 months, among phakic eyes initially 20/40 or better, the incidence of a reduction in VA to worse than 20/40 attributed to cataract was 20.2% [95%CI: 15.9-25.6]; cataract surgery was performed within 12 months in 13.8 % [95%CI: 11.1-17.2] of the initially phakic eyes

    Chronic lateral ankle instability causes significant problems in physical activity and accelerates development of osteoarthritic changes. The results of treatment for chronic ankle instability are often meets controversial. A surgical reconstruction of ATFL as described in this paper was performed during the period 1997-2005 on 47 patients (26 male, 21 female), with a mean age of 29.3 years. The average follow-up period was 46.2 months. All patients had clinical examination, X-ray and MRI. The mean values of the Good score improved from an average 3.32 prior to surgery to 1.19 one year after the operation. Paired t-tests showed improvements of great significance (p < 10(-28)). The Good score prior to surgery ranged from 2-4, whereas the scores one year after surgery were either 1 or 2, with a score of 1 being recorded in 38 cases (81%). In the postoperative follow-up, MRI showed a newly-formed ligament structure in all cases. The authors describe their own technique for a reconstruction of lateral ankle instability using remnants of the former ATFL. The scar tissue seems to be sufficient to form a new duplicated structure providing good stability. MRI proved to be a sensitive and specific method for identifying the extent of talo-fibular ligament injury.

    A 6 year-old girl with juvenile psoriatic arthritis (JPsA) and bilateral complicated anterior uveitis developed several ocular complications that required 5 surgical procedures. Despite the aggressive course of ocular inflammation, her visual acuity remained good. Arthritis (main criterion for the diagnosis of JPsA) appeared years after ocular involvement. She showed a good anti-tumour necrosis factor initial response. The definitive diagnosis of JPsA was established years after the onset of symptoms. In addition, the patient maintained a good visual acuity, despite its complicated disease course. Finally, she showed a good clinical response to adalimumab.

    1 Treatment of eight healthy males with propranolol (80 mg twice daily) for 6 weeks resulted in a significant reduction in overnight plasma levels of prolactin and LH. 2 Plasma testosterone levels were elevated whilst GH and cortisol were unchanged by such treatment. 3 Measurement of overnight hormone levels 48 h after discontinuing treatment showed no evidence of a 'rebound' phenomenon. 4 Cortisol, GH, prolactin, and testosterone plasma levels all showed time dependent changes: propranolol treatment significantly altered the time course of cortisol but not of the other hormones. 5 The effects of chronic propranolol treatment are discussed in terms of a probable direct central action of the drug. In addition the lowered plasma prolactin levels may directly contribute to the hypotensive action of propranolol. PMID:7340886

    Lateral ankle sprains may result in pain and disability in the short term, decreased sport activity and early retirement from sports in the mid term, and secondary injuries and development of early osteoarthritis to the ankle in the long term. This combined approach to chronic lateral instability and intra-articular lesions of the ankle is safe and in the long term maintains mechanical stability, functional ability, and a good level of sport activity. Case series; Level of evidence, 4. We present the long-term outcomes of 42 athletes who underwent ankle arthroscopy and anterior talofibular Broström repair for management of chronic lateral ankle instability. We assessed in all patients preoperative and postoperative anterior drawer test and side-to-side differences, American Orthopaedic Foot and Ankle Society (AOFAS) score, and Kaikkonen grading scales. Patients were asked about return to sport and level of activity. Patients were also assessed for development of degenerative changes to the ankle, and preoperative versus postoperative findings were compared. Thirty-eight patients were reviewed at an average of 8.7 years (range, 5-13 years) after surgery; 4 patients were lost to follow-up. At the last follow-up, patients were significantly improved for ankle laxity, AOFAS scores, and Kaikkonen scales. The mean AOFAS score improved from 51 (range, 32-71) to 90 (range, 67-100), and the mean Kaikkonen score improved from 45 (range, 30-70) to 90 (range, 65-100). According to outcome criteria set preoperatively, there were 8 failures by the AOFAS score and 9 by the Kaikkonen score. Twenty-two (58%) patients practiced sport at the preinjury level, 6 (16%) had changed to lower levels but were still active in less demanding sports (cycling and tennis), and 10 (26%) had abandoned active sport participation although they still were physically active. Six of these patients did not feel safe with their ankle because of the occurrence of new episodes of ankle instability. Of the

    To assess the usefulness of laser flare-cell photometry to quantify intraocular inflammation in patients with Behçet disease. The study comprised 47 healthy individuals, 78 Behçet patients without ocular involvement, 54 Behçet patients with a uveitis attack and 53 Behçet patients with uveitis in clinical remission. A single observer assigned clinical scores to anterior chamber cells, vitreous haze, and fundus lesions in the attack group. Laser flare-cell photometry measurements were performed by another observer who was masked to the clinical findings. Fundus fluorescein angiography was performed only in the remission group, and fluorescein leakage was scored by a masked retina specialist. The risk of recurrent uveitis attack was analyzed in eyes with high versus low flare values in the remission group. Main outcome measures were anterior chamber flare in Behçet patients compared to the control group, and correlations of flare with clinical scores of intraocular inflammation and with fluorescein leakage. Mann-Whitney U-test, Spearman's bivariate correlation test, linear regression method, and Kaplan-Meier method were used for statistical analyses. Mean flare was not increased in Behçet patients without ocular involvement. It was significantly higher in patients with Behçet uveitis both during attacks and in remission (P < 0.001 for each). A significant correlation was found between anterior chamber flare and anterior chamber cell score (rho = 0.705), vitreous haze score (rho = 0.588), and fundus score (rho = 0.464) in the attack group. In the remission group, there was a significant correlation between flare and fluorescein angiography leakage score, and the risk of recurrent uveitis attack was significantly higher in eyes with flare values >6 photons/msec than in eyes with flare values < or =6 photons/msec (right eyes, P < 0.001; left eyes, P = 0.0184).

    Repetitive transcranial magnetic stimulation (rTMS) has been proposed as a tinnitus treatment option. Promising results have been obtained by consecutive stimulation of lateral frontal and auditory brain regions. We investigated a combined stimulation paradigm targeting the anterior cingulate cortex (ACC) with double cone coil rTMS, followed by stimulation of the temporo-parietal junction area with a figure-of-eight coil. The study was conducted as a randomized, double-blind pilot trial in 40 patients suffering from chronic tinnitus. We compared mediofrontal stimulation with double-cone-coil, (2000 stimuli, 10 Hz) followed by left temporo-parietal stimulation with figure-of-eight-coil (2000 stimuli, 1 Hz) to left dorsolateral-prefrontal-cortex stimulation with figure-of-eight-coil (2000 stimuli, 10 Hz) followed by temporo-parietal stimulation with figure-of-eight-coil (2000 stimuli, 1 Hz). The stimulation was feasible with comparable dropout rates in both study arms; no severe adverse events were registered. Responder rates did not differ in both study arms. There was a significant main effect of time for the change in the TQ score, but no significant time x group interaction. This pilot study demonstrated the feasibility of combined mediofrontal/temporoparietal-rTMS-stimulation with double cone coil in tinnitus patients but failed to show better outcome compared to an actively rTMS treated control group.

    Background Rapamycin, a potent immune modulator, is used to treat transplant rejection and some autoimmune diseases. Uveitis is a potentially severe inflammatory eye disease, and 2 clinical trials of treating uveitis with rapamycin are under way. Unexpectedly, recent research has demonstrated that low dose rapamycin enhances the memory T cell population and function. However, it is unclear how low dose rapamycin influences the immune response in the setting of uveitis. Design and Methods B10.RIII mice were immunized to induce experimental autoimmune uveitis (EAU). Ocular inflammation of control and rapamycin-treated mice was compared based on histological change. ELISPOT and T cell proliferation assays were performed to assess splenocyte response to ocular antigen. In addition, we examined the effect of rapamycin on activation-induced cell death (AICD) using the MitoCapture assay and Annexin V staining. Results Administration of low dose rapamycin exacerbated EAU, whereas treating mice with high dose rapamycin attenuated ocular inflammation. The progression of EAU by low dose rapamycin coincided with the increased frequency of antigen-reactive lymphocytes. Lastly, fewer rapamycin-treated T cells underwent AICD, which might contribute to exaggerated ocular inflammation and the uveitogenic immune response. Conclusion These data reveal a paradoxical role for rapamycin in uveitis in a dose-dependent manner. This study has a potentially important clinical implication as rapamycin might cause unwanted consequences dependent on dosing and pharmacokinetics. Thus, more research is needed to further define the mechanism by which low dose rapamycin augments the immune response. PMID:22574188

    Aim The aim of this study is to characterise the choroidal features of patients diagnosed with sarcoid- and tuberculosis (TB)-associated granulomatous uveitis using spectral domain optical coherence tomography (OCT). Methods Twenty-seven patients (27 eyes) diagnosed with sarcoid- (13 eyes) and TB (14 eyes)-related uveitis were included in this retrospective, cross-sectional study. Over a six-month period, patients diagnosed with sarcoid and TB granulomatous uveitis were scanned using enhanced depth imaging OCT. Clinical and demographical characteristics were recorded, including the method of diagnosis, disease activity, site of inflammation (anterior or posterior), treatments, and visual acuity (VA). Manual segmentation of the choroidal layers was performed using custom image analysis software. Results The main outcome measure was OCT-derived thickness measurements of the choroid and choroidal sublayers (Haller's large vessel and Sattler's medium vessel layers) at the macula region. The ratio of Haller's large vessel to Sattler's medium vessel layer was significantly different at the total macula circle in eyes diagnosed with TB uveitis (1.47 (=140.71/95.72 μm)) compared with sarcoid uveitis (1.07 (=137.70/128.69 μm)) (P=0.001). A thinner choroid was observed in eyes with a VA ≥0.3 LogMAR (Snellen 6/12; 198.1 μm (interquartile range (IQR)=147.0–253.4 μm) compared with those with VA <0.3 LogMAR (292.4 μm (IQR=240.1–347.6 μm)) at the total macula circle (P=0.004). At the foveal central subfield, the median choroidal thickness was 336.8 μm (IQR=272.3–375.4 μm) in active compared with 239.3 μm (IQR=195.3–330.9 μm) in quiescent disease (P=0.04). Conclusion A disproportionately enlarged Sattler's layer may indicate a diagnosis of sarcoid-related uveitis, and choroidal thickening may be a feature of active granulomatous uveitis. PMID:26021867

    Viruses are a fundamental etiology of ocular inflammation, which may affect all structures of the organ. Advances in molecular diagnostics reveal an increasingly broader spectrum of virus-associated intraocular inflammation, including all members of the herpes family, rubella virus, and other more rare causes such as Epstein–Barr and chikungunya virus. In particular, viruses of the herpes family are important causes of anterior and posterior uveitis. Owing to their often fulminant clinical course and persistence in ocular tissues, a clear differential diagnosis between alpha- and beta-type herpes viruses is essential to guide acute and long-term treatment. Here, we review the epidemiology, clinical, and laboratory findings of virus-associated uveitis with emphasis on their therapy and management and include our own experience. PMID:26089633

    2004-07-01

    It is postulated that an anterior anal fissure can result from mucosal trauma occurring during distention of a rectocele and that repair of the rectocele by anterior levatorplasty can lead to healing of these anal fissures. This study was designed to compare anterior levatorplasty with internal sphincterotomy for the management of anterior anal fissures in females with a rectocele. From June 2000 until May 2002, 54 consecutive females with an anterior anal fissure and a rectocele were randomized to be managed by internal sphincterotomy or anterior levatorplasty. Preoperatively, manometry was performed, continence was measured using the Cleveland Clinic scoring system, pain scores were obtained using a visual analog scale, and the symptoms of bleeding and straining to defecate were assessed. Postoperatively, pain scores were obtained at Days 2, 7, and 21. Manometry, continence scores, and resolution of symptoms were measured between 8 and 12 weeks. Patient satisfaction and fissure healing also were assessed between 8 and 12 weeks. The average length of follow-up was 20 (range, 6-30) months. Postoperatively, lateral sphincterotomy caused a decrease in the resting pressures and anterior levatorplasty resulted in an increased length of the anal canal. Anterior levatorplasty also caused increased postoperative pain scores. There were no differences in fissure healing and patient satisfaction. These data suggest that anterior levatorplasty is an option for the management of patients with a rectocele, which may avoid the risk of incontinence with lateral internal sphincterotomy and better address the etiology of anterior anal fissures.

    Systemic rheumatic conditions are often accompanied by intraocular inflammatory disease (termed uveitis). Despite the frequent manifestation of uveitis with arthritis, very little is understood of the underlying mechanisms that mediate the eye's susceptibility to disease. The genetically susceptible SKG mouse strain develops arthritis that arises from an inherent mutation that disrupts T-cell antigen receptor signal transduction and thymic selection. The ensuing T-cell-mediated disease is further modulated through exposure to microbial triggers. The purpose of this study was to elucidate how a genetically determined shift in the T-cell repertoire toward self-reactive T cells that drive arthritis influences uveitis in SKG mice. SKG mice (BALB/c mice that harbor the W163C point mutation in zeta-chain-associated protein kinase 70 [i.e., ZAP-70]) were housed under arthritis-resistant, specific pathogen-free conditions. Arthritis was induced by intraperitoneal injection with fungal glucans (zymosan or curdlan). Arthritis onset and severity were evaluated by clinical scoring, histopathology and infrared imaging within the joints. Periocular traits involving blepharoconjunctivitis were evaluated by clinical scoring and histology. Eyes were evaluated for signs of anterior uveitis using intravital videomicroscopy to document cell-trafficking responses within the iris vasculature and stroma and by histology to detect inflammatory infiltrate and tissue damage within the anterior and posterior eye segments. Exposure to zymosan resulted in the predicted arthritic, sexually dimorphic phenotype in SKG mice. The eyes of SKG mice exhibited episodic intravascular cellular responses to zymosan or curdlan as indicated by significant increases in leukocyte-endothelium interactions akin to ocular vasculitis. However, despite the significant increase in early cell-trafficking responses, cellular infiltration into the iris stroma was not observed and histopathological signs indicative of

    Background/aims: Pregnancy and the postpartum period are associated with the activity of autoimmune diseases including uveitis. Although the exact mechanism is unknown, hormones are reported to alter inflammatory cytokines and influence disease activity. The authors studied ocular inflammation, female hormones, and serum cytokine levels during and after pregnancy. Methods: A prospective, observational case study was conducted. Four pregnant women in their first trimester with chronic non-infectious uveitis were followed monthly until 6 months after delivery. Serum female hormones (oestrogen, progesterone, prolactin) and various cytokines (IL-2, IL-4, IL-5, IL-6, IL-10, IFN-γ, and TGF-β) were measured by ELISA. Results: The four patients had five full term pregnancies. Uveitis activity decreased after the first trimester but flared in the early postpartum period. Serum female hormones, highly elevated during pregnancy, drastically dropped post partum. Cytokine levels except TGF-β were mostly undetectable. Conclusion: Female hormones and TGF-β may contribute to the activity of uveitis during pregnancy and the postpartum period. PMID:15548800

    Uveitis is a vision threatening inflammation of the eye that carries considerable morbidity. It is responsible for 10% of legal blindness in the United States and up to 25% in the developing world. Uveitis in patients more than 60 years of age is less common. The aging body has a changing response of the immune system, which might reflect a different pattern of uveitis in the elderly population. In this paper we review the incidence and patterns of uveitis in the elderly as reported in the literature and discuss changes with time. We also delineate a thorough differential diagnosis of de novo uveitis in the elderly. PMID:26090218

    2015-01-01

    Interleukin-6 (IL-6) is a pleiotropic cytokine implicated in the pathogenesis of many immune-mediated disorders including several types of non-infectious uveitis. These uveitic conditions include Vogt-Koyanagi-Harada syndrome, uveitis associated with Behçet disease, and sarcoidosis. This review summarizes the role of IL-6 in immunity, highlighting its effect on Th17, Th1, and plasmablast differentiation. It reviews the downstream mediators activated in the process of IL-6 binding to its receptor complex. This review also summarizes the biologics targeting either IL-6 or the IL-6 receptor, including tocilizumab, sarilumab, sirukumab, olokizumab, clazakizumab, and siltuximab. The target, dosage, potential side effects, and potential uses of these biologics are summarized in this article based on the existing literature. In summary, anti-IL-6 therapy for non-infectious uveitis shows promise in terms of efficacy and side effect profile.

    Uveitis is an inflammatory process that initially starts in the uvea, but can also affect other adjacent eye structures, and is currently the fourth cause of blindness in developed countries. Corticoids are probably the most widespread treatment, but resorting to other immunosuppressive treatments is a frequent practice. Since the implication of different cytokines in uveitis has been well demonstrated, the majority of recent treatments for this disease include inhibitors or antibodies against these. Nevertheless, adequate treatment for each uveitis type entails a difficult therapeutic decision as no clear recommendations are found in the literature, despite the few protocolized clinical assays and many case-control studies done. This review aims to present, in order, the mechanisms and main indications of the most modern immunosuppressive drugs against cytokines. PMID:26270662

    The model of experimental autoimmune uveitis (EAU) in mice and in rats is described. EAU targets immunologically privileged retinal antigens and serves as a model of autoimmune uveitis in humans as well as a model for autoimmunity in a more general sense. EAU is a well-characterized, robust, and reproducible model that is easily followed and quantitated. It is inducible with synthetic peptides derived from retinal autoantigens in commonly available strains of rats and mice. The ability to induce EAU in various gene-manipulated, including HLA-transgenic, mouse strains makes the EAU model suitable for the study of basic mechanisms as well as in clinically relevant interventions.

This tremendous increase in precision and accuracy in the assessment of the level and degree of inflammation and its monitoring comes in parallel with the development of extremely potent and efficacious therapies. In view of these developments, our whole attitude in the appraisal and investigation of the uveitis patient has to be adapted and correctly reoriented integrating the recent developments and this is no different for ocular angiography.

    Uveitis is a common cause of preventable blindness although it is consider a sight-threatening condition particularly in cases with posterior segment inflammation. To deal with emergency conditions in uveitis, we must aware of the essential signs and symptoms that reflect a true uveitic emergency. Failure to recognize these essential signs and symptoms of a true uveitic emergency may result in a devastating visual outcome. This review provides general ophthalmologists and residents, clinical guidelines for the main uveitic entities that require immediate recognition and urgent intervention in the emergency room to prevent severe permanent visual loss.

    Background: Percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) of the left anterior descending (LAD) specifically is associated with improved long-term 5 year survival as compared to PCI failure. The procedure is associated with usage of different types of dedicated guidewires by simple or complex techniques aiming to reopen the occluded artery. Aim: To describe types and outcome of guidewires used in LAD-CTO utilizing a first intentional single wiring simple strategy. Methods: A single center prospective registry for all consecutive patients with a PCI attempt to a native LAD CTO. The initial strategy for lesion crossing was Single wiring. Results: A total of 30 patients with LAD CTO lesions (100%), were recorded. Mean age was 71.6 + 15 years, 77% were Males, risk factors Hypertension in 63%, Diabetes 27%, Dyslipidemia 57%, smoking 40%, hereditary in 13% of patients. Isolated guidewire (GW) success rate was very high 93%. Single wiring was the prevailing technique used in 97% of successfull lesions (83% of total cases) while only 3% were by multiple wiring techniques. Successful single antegrade wiring represented 63% with a GW success rate of 92% of cases. Successful single retrograde wiring represented 13% with a GW success rate of 67%. Successful Crossing GW types in our patients were 44% Soft Tapered GWs; fielder XT (44%), 36% were Soft Non Tapered Pilot 50 (28%), whisper (8%), while 16% were Stiff Non tapered GWs; Miracle 12 (8%), Miracle 6 (4%), Miracle 3 (4%), and 4% were Stiff Tapered GWs; Progress 200 (4%). Conclusions: Single wiring as an initial strategy in PCI for LAD-CTO lesions has a high success rate and is associated with a 44% majority of Soft Tapered GWs, 36% Soft Non Tapered, 16% Stiff Non tapered GWs, and 4% Stiff Tapered GWs.

    Purpose To assess the prevalence of hypotony in patients with severe forms of uveitis. Methods The Multicenter Uveitis Steroid Treatment (MUST) Trial, a randomized study, enrolled 255 patients. Patients with hypotony at the baseline visit were identified. Results Twenty (8.3%) of 240 patients with sufficient data had hypotony. Hypotony was more common in patients with uveitis ≥5 years duration (odds ratio [OR] = 5.0; p < .01), and in eyes with a history of ocular surgery (vitrectomy vs. none, OR = 3.1; p = .03). Hypotony was less in patients with older age of uveitis onset (>51 years vs. <51 years, OR = 0.1; p = .02), in Caucasian patients (OR = 0.1; p < .01) compared to African American patients. Hypotonous eyes were more likely to have visual impairment (OR = 22.9; p < .01). Conclusions Hypotony is an important complication of uveitis and more commonly affects African-American patients, those with uveitis onset at a younger age, and those with longer disease duration. It is associated with visual impairment. PMID:22409563

    The results of comprehensive clinicoimmunologic examinations of 38 uveitis patients with Behçet's disease indicate that uveitis in the presence of Behçet's disease should be referred to multifactorial diseases to whose pathogenesis immunopathologic reactions in various combinations and genetic predisposition contribute much. Generalization of the process in the eye predominated in the clinical picture with involvement of the anterior and posterior segments, retinal vessels, this being combined with general somatic symptoms (aphthae on the buccal mucosa, genitals, arthritides, urethritis/cystitis symptoms, positive 'pricking' test). Study of the immunity status revealed depressed lymphocyte proliferative response to mitogen in 58.8% of patients, hyperimmunoglobulinemia of the A and M classes in 63.3%, impaired complex formation (increased levels of circulating immune complexes in 78.3% and cryoglobulin presence in 57.1%), and various combinations of these immunologic signs. The results indicated patients' infection with herpes virus, streptococcus, toxoplasma. An associative connection of Behçet's disease with A (II) red cell phenotype in 54.8% of patients (p < 0.05) suggests a relationship between genetic factors and the conditions of a specific geographic region. A variety of immunologic changes necessitated the use of corticosteroids, hemoperfusion, cytostatics, and immunity stimulants in the treatment of uveitis in Behçet's disease patients.

    This study set out to determine whether withdrawal of cyclosporin A (CyA) in Lewis rats sensitized to retinal S antigen would precipitate experimental autoallergic uveoretinitis (EAU), and whether challenge of such animals with S antigen or an unrelated stimulus would accelerate EAU onset after drug withdrawal. Rats were sensitized with 50 micrograms S antigen in Freund's complete adjuvant (FCA) and EAU onset was suppressed by 18 days of treatment with CyA at doses ranging from 3 to 10 mg/kg daily. Without challenge, seven out of 11 animals developed EAU with a median onset of 78 days. This was reduced to 68 days in rats challenged on day 32 with FCA alone, to 48 days with 10 micrograms S antigen in FCA, and to 41 days with 50 micrograms S antigen in FCA. The incidence, onset and severity of anterior uveitis and extent of photoreceptor destruction were related to both CyA dose and nature of challenge. The extent of photoreceptor destruction ran parallel with severity of anterior uveitis; and delayed-type hypersensitivity reactivity on day 43 was related to both severity of anterior uveitis (P less than 0.001) and photoreceptor damage (P less than 0.002). At the highest dose, CyA also delayed the appearance of antibody to S antigen; however, subsequent antibody levels were unrelated to EAU severity or to nature of challenge. The results indicate that CyA-induced suppression of the immunological response to S antigen can recover spontaneously after drug withdrawal, that challenge with either S antigen or FCA alone can accelerate the subsequent onset of EAU, and that these phenomena may provide a basis for investigating mechanisms underlying relapse of human uveoretinitis.

    Near-infrared spectroscopy measures muscle oxygen saturation (StO2) in the skeletal muscle and has been proposed as a noninvasive tool for diagnosing chronic anterior compartment syndrome (CACS). The purpose of this study was to investigate the diagnostic value of changes in StO2 during and after exercise in patients with CACS. The study comprised 159 consecutive patients with exercise-induced leg pain. Near-infrared spectroscopy was used to measure StO2 continuously before, during, and after an exercise test. One minute post-exercise, intramuscular pressure was recorded in the same muscle. The cohort was divided into patients with CACS (n = 87) and patients without CACS (n = 72) according to the CACS diagnostic criteria. Reoxygenation at rest after exercise was calculated as the time period required for the level of muscular StO2 to reach 50% (T50), 90% (T90), and 100% (T100) of the baseline value. The lowest level of StO2 during exercise was 1% (range, 1% to 36%) in the patients with CACS and 3% (range, 1% to 54%) in the patients without CACS. The sensitivity was 34% and the specificity was 43% when an StO2 level of ≤8% at peak exercise was used to indicate CACS. The sensitivity and the specificity were only 1% when an StO2 level of ≤50% at peak exercise was used to indicate CACS. The time period for reoxygenation was seven seconds (range, one to forty-three seconds) at T50, twenty-eight seconds (range, seven to seventy-seven seconds) at T90, and forty-two seconds (range, seven to 200 seconds) at T100 in the patients with CACS and ten seconds (range, one to forty-nine seconds) at T50, thirty-two seconds (range, four to 138 seconds) at T90, and forty-eight seconds (range, four to 180 seconds) at T100 in the patients without CACS. When thirty seconds or more at T90 was set as the cutoff value for a prolonged time for reoxygenation, indicating a diagnosis of CACS, the sensitivity was 38% and the specificity was 50%.

    This prospective randomized study compared acute and chronic anterior cruciate ligament (ACL) reconstruction using ligament advanced reinforcement system (LARS) artificial ligament in young active adults with a 5-year follow-up. Fifty-five patients were enrolled in this study and divided into two groups based on the elapsed time between the injury and reconstruction: the acute group (3-7 weeks) and the chronic group (6-11 months). The clinical outcomes were evaluated using the Lysholm knee scoring scale, the Tegner activity rating, a KT-1000 Arthrometer, and the International Knee Documentation Committee (IKDC) scoring system. Isokinetic strength of the quadriceps and hamstring was assessed using the Biodex System 3 isokinetic dynamometer. Anterior laxity was decreased and quadriceps/hamstring muscle strength was increased in the acute group compared to the chronic group (p > 0.05). There were no statistically significant differences in Lysholm scores, Tegner activity scores, and the IKDC evaluation form between the two groups. These results suggest that earlier ACL reconstruction using a LARS artificial ligament may provide an advantage in the treatment and rehabilitation of ACL rupture.

    Forty-four children aged 6 months to 14 years, suffering from endogenous uveitis of various sites were examined at different phases of the diseases by a scanning type apparatus, AGA-780M-thermographer (Sweden). The results permit a conclusion that long-distance thermography may be effectively used to assess the ocular status even in small restless children. Uveitis active phase was found associated with a hyperthermal reaction in all the examined sites. Hyperthermia was found related to uveitis localization. The authors suggest that thermoasymmetry parameters and the corneolimbic gradient be used as additional objective criteria for the assessment of uveitis activity and dissemination in children.

    Occasional reports of uveitis following topiramate use necessitated an investigation of relevant cases from safety databases and published biomedical literature. Data mining of the Food and Drug Administration Adverse Event Reporting System and cumulative review of cases from the global safety database (sponsor database) and published literature were conducted to assess association between topiramate use and uveitis. The Food and Drug Administration Adverse Event Reporting System search identified disproportional reporting of uveitis (n=23) and related terms (choroidal detachment, n=25; iridocyclitis, n=17). The postmarketing reporting frequency of uveitis and related events from the global safety database and based on an estimated topiramate exposure of 11,185,740 person-years from launch to April 2015 was 0.38 per 100,000 person-years and assigned as very rare. A total of 14 potential uveitis cases were identified from the cumulative review. Seven of these 14 cases were complicated by inadequate documentation, appearance of uveitic signs following drug withdrawal, or concurrent use of other sulfonamides. In acute angle-closure glaucoma and uveal effusions cases, insufficient evidence for underlying inflammation suggested that uveitis was not a component. Only seven of 14 cases were well documented, potentially topiramate-associated uveitis cases. Uveitis may occur in the setting of topiramate use only in very rare instances. Current evidence did not reveal a dose- or duration-dependent relationship between uveitis and topiramate use. PMID:27536060

    Equine recurrent uveitis (ERU) is a disease with high prevalence and relevance for the equine population, since it results in blindness. Over the last decade, important advancements have been made in our understanding of the underlying immune responses in this disease. ERU is mediated by an autoaggressive Th1 response directed against several retinal proteins. Interphotoreceptor-retinoid binding protein (IRBP) and cellular retinaldehyde-binding protein (CRALBP) are capable to induce ERU-like disease in experimental horses, with the unique possibility to activate relapses in a well-defined manner. Further, proteomic evidence now suggests that retinal Mueller glial cells (RMG) may play a fatal role in uveitic disease progression by directly triggering inflammation processes through the expression and secretion of interferon-gamma. Ongoing relapses in blind eyes can be associated with stable expression of the major autoantigens in ERU retinas. This review briefly summarizes the most significant developments in uveitis immune response research.

    We have previously demonstrated the effects of various inhibitors of arachidonic acid metabolism on experimental lens-induced granulomatous uveitis. In the present study, we investigated the effect of these same inhibitors on the expression of lysosomal enzymes at different stages of choroidal inflammation in experimental lens-induced granulomatous uveitis and compared this to the inflammation observed at each stage examined. Lysosomal enzymes such as acid phosphatase, beta-glucuronidase and succinate dehydrogenase are known to be liberated during the maturation of mononuclear phagocytes to epithelioid cell granulomas. Although animals treated with nordihydroguaiaretic acid showed less severe inflammation than did indomethacin-treated or control animals, none of these agents appeared to affect the expression of acid phosphatase and beta-glucuronidase, as determined histochemically. Succinate dehydrogenase could not be detected in any of the eyes examined, even though sections of liver and kidney from these same animals were positive for this enzyme.

    To investigate whether the combination of Fuchs' heterochromic uveitis (FHU) and retinitis pigmentosa (RP) in the same patient is coincidental or represents a true association. We have examined the frequency of FHU in 338 patients with RP and in 1984 patients who were seen in our primary care ophthalmic clinic because of reasons other than RP. Of 338 patients with RP, 4 (1.2%) had the typical findings of FHU. Three of them had Usher syndrome type II, and 1 had RP simplex. By contrast, only 1 patient in the control group had FHU (5%), and the difference in the frequency of FHU between the 2 groups was significant (P=.002, Fisher exact test). Fuchs' heterochromic uveitis is associated with RP. Since autoimmune phenomena have been previously described in patients with RP, it is conceivable that RP predisposes to the development of FHU.

    Although the phenomenon of fundus autofluorescence has been known for decades, it has only recently been recognized as a measure of retinal pigment epithelial function and health. Characteristic fundus autofluorescence patterns have been described in eyes affected by inflammation of the posterior segment, and these patterns have provided insights into the pathogenesis of posterior uveitis entities. In addition, preliminary data indicate that fundus autofluorescence characteristics may serve as markers of disease activity, allow prediction of visual prognosis, and may help determine the adequacy of therapy. We provide an overview of the current state of fundus autofluorescence imaging technology and review our current knowledge of fundus autoflourescence findings and their clinical use in the posterior uveitis entities.

    Combined anterior cruciate ligament, posterior cruciate ligament, and lateral-sided injuries of the knee most often occurs secondary to a forced varus moment or after knee dislocation. Management controversies include the optimal timing of surgery, operative techniques, and postoperative rehabilitation. Recent systematic literature reviews have demonstrated higher rates of failure with repair of the lateral and posterolateral corner structures, as opposed to reconstruction. However, the ideal ligament reconstruction techniques remain unclear. This chapter will review the combined anterior cruciate ligament/posterior cruciate ligament/lateral-sided injury pattern, including the physical examination findings, imaging, timing of surgery, graft selection, operative techniques, and postoperative rehabilitation protocols.

    Anterior thalamic lesions are thought to produce ‘covert pathology’ in retrosplenial cortex, but the causes are unknown. Microarray analyses tested the hypothesis that thalamic damage causes a chronic, hypo-function of metabolic and plasticity-related pathways (Experiment 1). Rats with unilateral, anterior thalamic lesions were exposed to a novel environment for 20 minutes, and granular retrosplenial tissue sampled from both hemispheres 30 minutes, 2h, or 8h later. Complementary statistical approaches (analyses of variance, predictive patterning and gene set enrichment analysis) revealed pervasive gene expression differences between retrosplenial cortex ipsilateral to the thalamic lesion and contralateral to the lesion. Selected gene differences were validated by QPCR, immunohistochemistry (Experiment 1), and in situ hybridisation (Experiment 2). Following thalamic lesions, the retrosplenial cortex undergoes profuse cellular transcriptome changes including lower relative levels of specific mRNAs involved in energy metabolism and neuronal plasticity. These changes in functional gene expression may be largely driven by decreases in the expression of multiple transcription factors, including brd8, c-fos, fra-2, klf5, nfix, nr4a1, smad3, smarcc2, and zfp9, with a much smaller number (nfat5, neuroD1, RXRγ) showing increases. These findings have implications for conditions such as diencephalic amnesia and Alzheimer’s disease, where both anterior thalamic pathology and retrosplenial cortex hypometabolism are prominent.

    Purpose Among cases of visually significant uveitic macular edema (ME), to estimate the incidence of visual improvement and identify predictive factors. Design Retrospective cohort study. Participants Eyes with uveitis, seen at five academic ocular inflammation centers in the United States, for which ME was documented to be currently present and the principal cause of reduced visual acuity (worse than 20/40). Methods Data were obtained by standardized chart review. Main Outcome Measures Decrease of at least 0.2 logMAR (base 10 logarithm of visual acuity decimal fraction)-equivalent; risk factors for such visual improvement. Results We identified 1,510 eyes (of 1,077 patients) with visual impairment to a level worse than 20/40 attributed to ME. Most patients were female (67%) and white (76%), and had bilateral uveitis (82%). The estimated six-month incidence of at least two lines of visual acuity improvement in affected eyes was 52% (95% confidence interval [CI], 49%–55%). Vision reduced by ME was more likely to improve by two lines in eyes initially with poor visual acuity (20/200 or worse; adjusted hazard ratio [HR] 1.5, 95% CI 1.3–1.7), active uveitis (HR 1.3, 95% CI 1.1–1.5), and anterior uveitis as opposed to intermediate (HR=1.2), posterior (HR=1.3) or panuveitis (HR=1.4) (overall p=0.02). During follow-up, reductions in anterior chamber or vitreous cellular activity or in vitreous haze each led to statistically significant improvements in visual outcome (p<0.001 for each). Conversely, snowbanking (HR 0.7, 95% CI 0.4–0.99), posterior synechiae (HR 0.8, 95% CI 0.6–0.9), and hypotony (HR 0.2, 95% CI 0.06–0.5) each were associated with lower incidence of visual improvement with respect to eyes lacking each of these attributes at a given visit. Conclusions These results suggest that many, but not all, patients with ME causing low vision in a tertiary care setting will enjoy meaningful visual recovery in response to treatment.

    To identify factors associated with best-corrected visual acuity (BCVA) presentation and 2-year outcome in 479 intermediate, posterior, and panuveitic eyes. Cohort study using randomized controlled trial data. Multicenter Uveitis Steroid Treatment (MUST) Trial masked BCVA measurements at baseline and at 2 years follow-up used gold-standard methods. Twenty-three clinical centers documented characteristics per protocol, which were evaluated as potential predictive factors for baseline BCVA and 2-year change in BCVA. Baseline factors significantly associated with reduced BCVA included age ≥50 vs <50 years; posterior vs intermediate uveitis; uveitis duration >10 vs <6 years; anterior chamber (AC) flare >grade 0; cataract; macular thickening; and exudative retinal detachment. Over 2 years, eyes better than 20/50 and 20/50 or worse at baseline improved, on average, by 1 letter (P = .52) and 10 letters (P < .001), respectively. Both treatment groups and all sites of uveitis improved similarly. Factors associated with improved BCVA included resolution of active AC cells, resolution of macular thickening, and cataract surgery in an initially cataractous eye. Factors associated with worsening BCVA included longer duration of uveitis (6-10 or >10 vs <6 years), incident AC flare, cataract at both baseline and follow-up, pseudophakia at baseline, persistence or incidence of vitreous haze, and incidence of macular thickening. Intermediate, posterior, and panuveitis have a similarly favorable prognosis with both systemic and fluocinolone acetonide implant treatment. Eyes with more prolonged/severe inflammatory damage and/or inflammatory findings initially or during follow-up have a worse visual acuity prognosis. The results indicate the value of implementing best practices in managing inflammation. Copyright © 2015 Elsevier Inc. All rights reserved.

Results The index case was initially referred for unexplained severe and chronic postoperative bilateral uveitis following a standard cataract surgery procedure. Clinical examination of the proband revealed an optically empty vitreous with avascular vitreous strands and veils, features highly suggestive of WS. The systematic familial ophthalmologic examination identified three additional unsuspected affected family members who also presented with the WS phenotype, including uveitis for one of them. We identified a novel c.4004–6T>A nucleotide substitution at the acceptor splice site of intron 7 of the VCAN gene that segregated with the disease phenotype. Conclusions We present a family with WS with typical WS features and intraocular inflammatory manifestations associated with a novel splice site VCAN mutation. Beyond the structural role in the retinal-vitreous architecture, versican is also emerging as a pivotal mediator of the inflammatory response, supporting uveitis predisposition as a clinical manifestation of WS.

    Purpose: To present challenging cases of vitreoretinal lymphoma (VRL) that was misdiagnosed as uveitis because of the apparent intraocular inflammation. At the light of the new classification of intraocular lymphomas, we detail the characteristics that masqueraded the tumors and the clinical aspects that guided us to the correct diagnosis. Materials and Methods: We retrospectively reviewed the patients referred to our uveitis service between January 2006 and December 2014. Results: Seven patients referred with a presumptive diagnosis of idiopathic uveitis received a final diagnosis of VRL. The median time between the onset of symptoms and definitive diagnosis was 25 months for these complex cases. The median time from presentation at our clinic to final diagnosis was 1 month. The described clinical features including dense vitreous cells and subretinal infiltrates were characteristic and tend to be present in all these chronically ill patients. Vitreous samples were collected, and all demonstrated the pathognomonic tumor cells, the specific immunoglobulin heavy chain gene rearrangements, and an interleukin (IL)-10 to IL-6 ratio >1. Conclusion: VRLs are severe diseases with a poor prognosis that may be misdiagnosed as idiopathic inflammatory conditions of the eye. Treatment with steroids may occult the tumors and delay the correct diagnosis. Appropriate evaluation may prompt to a timely vitreous sampling and therefore to a faster diagnosis in these peculiar cases where the correct diagnosis was delayed by several months. PMID:27380976

    To evaluate the association between intraocular inflammation and laser flare photometry measurements in Behçet disease. In total, 45 patients were included in the study. The retrospective chart reviews of patients were performed. The flare levels were compared with the grade of anterior chamber cells, the presence of vitreous cells, the complications of uveitis, and fluorescein angiography scores. The attack group had higher flare intensity; the flare levels were higher in both groups compared with the values of healthy controls. The flare levels were related to the grade of the anterior chamber cells, the presence of vitreous cells and the fluorescein angiography scores. Patients with optic atrophy and/or maculopathy also had higher values. Higher flare values were correlated with poor vision. Laser flare photometry may reduce the necessity of fluorescein angiography in monitoring subclinical inflammation and may be an indicator of posterior segment activity when fluorescein angiography is not applicable.

  10. Uveitis: advances in understanding of pathogenesis and treatment.

    Uveitis is a leading cause of blindness affecting individuals of all ages, genders, and races. Uveitis may be due to autoimmune, infectious, toxic, malignant, or traumatic processes. Some evidence supports an association between conditions previously presumed to be autoimmune and viral infectious agents. For autoimmune uveitis, therapy is nonspecific, typically beginning with corticosteroids. For nonresponsive disease or for corticosteroid sparing, recent reports on mycophenolate mofetil, infliximab, and interferon therapy show success for various forms of uveitis. Treatment of the complications of uveitis, especially cystoid macular edema, is difficult. Vitamin E appears to offer little benefit, whereas octreotide may be effective. Recent collaborative efforts at standardization in the field should enhance studies on these conditions.

    Purpose To evaluate the safety, tolerability, and preliminary efficacy of suprachoroidal injection of triamcinolone acetonide (TA) in patients with noninfectious uveitis. Methods In this Phase 1/2 open-label clinical study, a single suprachoroidal injection of 4-mg TA in 100 μL was performed in the study eye of patients with noninfectious intermediate, posterior, or pan-uveitis, and follow-up obtained for 26 weeks. Results Nine individuals with chronic uveitis were enrolled. There were 38 reported adverse events (AEs); most were mild or moderate in severity. Approximately half the AEs were ocular. The most common AE was reported by four subjects who experienced ocular pain at or near the time of the injection. All systemic AEs were unrelated to study drug. No steroid-related increases in intraocular pressure (IOP) were observed and no subject required IOP-lowering medication. All eight efficacy-evaluable subjects had improvements in visual acuity. Four subjects, who did not need additional therapy, had on average a greater than 2-line improvement in visual acuity through week 26. Three of four had macular edema at baseline, and two of three had at least a 20% reduction in macular edema at week 26. Conclusions The safety and preliminary efficacy data support further investigations of suprachoroidally administered TA as a therapeutic option for the treatment of noninfectious uveitis. Translational Relevance Targeted suprachoroidal administration of corticosteroid is a potential local route for the treatment of ocular inflammatory disease, which merits further investigation.

    Aim: The aim of this study is to describe the clinical features and diagnostic criteria of Fuchs’ uveitis (FU) and to determine whether it has an association with virus and toxoplasma in the aqueous humor during cataract surgery. Setting and Design: This is a prospective, case–control study. Materials and Methods: Patients with FU (n = 25), anterior uveitis (n = 15), and no uveitis (normal) (n = 50) were included based on predefined inclusion and exclusion criteria for all three groups. Polymerase chain reaction (PCR) of aqueous humor and serum for rubella, herpes simplex virus (HSV), cytomegalovirus (CMV), varicella-zoster virus (VZV), and toxoplasma was done using conventional uniplex PCR. Statistical Analysis: It was done using SPSS software using Chi-square test for categorical variables, and P < 0.05 was considered statistically significant. Results: Ninety patients were enrolled in the study in three groups, comparable for age, gender, and laterality of ocular involvement. All patients had diffuse keratic precipitates in FU group (P = 0001) with none having posterior synechiae (P = 0.046) which was statistically significant when compared to anterior uveitis patients. Iris nodules were noted in one case in both groups. Serum and aqueous PCR was negative for detection of VZV, CMV, toxoplasma, and rubella in all groups. PCR for HSV was positive in one patient in “normal” group but was not statistically significant. Conclusion: Our study shows that diagnosis of FU is mainly clinical. There appears to be no role of aqueous humor testing for viruses by PCR to aid in etiological diagnosis. PMID:27688274

    Background Typically juvenile idiopathic arthritis (JIA)-associated uveitis (further referred as ‘JIA-uveitis’) has its onset in childhood, but some patients suffer its, sometimes visual threatening, complications or ongoing disease activity in adulthood. The objective of this study was to analyze uveitis activity, complications and visual prognosis in adulthood. Methods In this multicenter study, 67 adult patients (129 affected eyes) with JIA-uveitis were retrospectively studied for best corrected visual acuity, visual fields, uveitis activity, topical/systemic treatments, ocular complications, and ocular surgeries during their 18th, 22nd and 30th year of life. Because treatment strategies changed after the year 1990, outcomes were stratified for onset of uveitis before and after 1990. Results Sixty-two of all 67 included patients (93%) had bilateral uveitis. During their 18th life year, 4/52 patients (8%) had complete remission, 28/52 (54%) had uveitis activity and 37/51 patients (73%) were on systemic immunomodulatory treatment. Bilateral visual impairment or legal blindness occurred in 2/51 patients (4%); unilateral visual impairment or legal blindness occurred in 17/51 patients (33%) aged 18 years. The visual prognosis appeared to be slightly better for patients with uveitis onset after the year 1990 (for uveitis onset before 1990 (n = 7) four patients (58%) and for uveitis onset after 1990 (n = 44) 13 patients (30%) were either visual impaired or blind). At least one ocular surgery was performed in 10/24 patients (42%) between their 18th and 22nd year of life. Conclusions Bilateral visual outcome in early adulthood in patients with JIA-uveitis appears to be fairly good, although one third of the patients developed one visually impaired or blind eye. However, a fair amount of the patients suffered from ongoing uveitis activity and needed ongoing treatment as well as surgical interventions. Awareness of these findings is important for ophthalmologists and

    Intracerebral microdialysis was used to examine the function of the terminal 5-hydroxytryptamine (5-HT) autoreceptor in the anterior hypothalamus of anaesthetized rats at two points in the light phase of the light–dark cycle.Infusion of the 5-HT1A/1B agonist 5-methoxy-3-(1,2,3,6-tetrahydro-4-pyridyl)-1H-indole (RU24969) 0.1, 1.0 and 10 μM through the microdialysis probe led to a concentration-dependent decrease (49, 56 and 65% respectively) in 5-HT output. The effect of RU24969 (1 and 5 μM) was prevented by concurrent infusion of methiothepin (1 and 10 μM) into the anterior hypothalamus via the microdialysis probe. Infusion of methiothepin alone (1.0 and 10 μM) increased (15 and 142% respectively) 5-HT output.Infusion of RU24969 (5 μM) through the probe at mid-light and end-light resulted in a quantitatively greater decrease in 5-HT output at end-light compared with mid-light.Following treatment with either paroxetine hydrochloride (10 mg kg−1 i.p.) or desipramine hydrochloride (10 mg kg−1 i.p.) for 21 days the function of the terminal 5-HT1B autoreceptor was more markedly attenuated at end-light.The data show that, as defined by the response to RU24969, the function of the 5-HT1B receptors that control 5-HT output in the anterior hypothalamus is attenuated following chronic desipramine or paroxetine treatment in a time-of-day-dependent manner.

    Ipilimumab, a monoclonal antibody that blocks cytotoxic T-lymphocyte-associated antigen-4, leading to enhanced T-cell activation and proliferation, is associated with improved overall survival in melanoma. Its use can result in immune-related adverse events, the most common of which are skin rash, diarrhea, and colitis. Ipilimumab-induced hypophysitis is uncommon, mostly involves anterior pituitary, and is associated with abnormalities in pituitary MRI, whereas uveitis has been rarely reported. These immune-related adverse events occur during therapy. This report describes a patient who developed uveitis and hypophysitis involving both anterior and posterior pituitary, without MRI findings more than 3 weeks after the fourth dose of ipilimumab. This case illustrates the unusual presentation of and diagnostic challenges associated with ipilimumab-induced immune-related adverse events.

  16. Equine recurrent uveitis: the viewpoint from the USA.

    PubMed

    Equine recurrent uveitis (ERU) is a common disease in horses in the USA. There have been many advances in the treatment of ERU; however, frequent misdiagnosis of ERU occurs in cases of primary corneal or uveal disease. It is critical to remember that primary uveitis (i.e. one bout of inflammation) is a different disease to ERU, which is an immune mediated recurrent uveitis. Standard symptomatic anti-inflammatory therapy is effective to control most cases of ERU; however, some horses require advanced therapy, such as placement of drug delivery devices or removal of the vitreous, when they fail to respond to the standard therapy.

    Chronic pain with mood disorder, resulting from a peripheral nerve injury, is a serious clinical problem affecting the quality of life. A lack of brain-derived neurotrophic factor (BDNF) and abnormal intercellular signaling in the brain can mediate this symptom. BDNF is induced in cultured neurons by 4-methylcatechol (4-MC), but little is known about its role in pain-emotion. Thus, we characterized the actions of 4-MC on TrkB receptor-related pERK and BDNF mRNA in discreet brain regions related to pain-emotion after chronic pain in rat. Rats implanted with a stainless steel cannula into the lateral ventricular were subjected to chronic constriction injury (CCI). Pain was assessed by changes in paw withdrawal latency (PWL) to heat stimuli after CCI. Immobility time during the forced swimming testing was measured for depression-like behavior. Analgesic and antidepression modulations with 4-MC were examined by an anti-BDNF antibody (K252a, a TrkB receptor inhibitor). The animals were perfused and fixed (4% paraformaldehyde) for immunohistochemistry analysis (c-FOS/pERK). BDNF mRNA expression (anterior cingulate cortex) was determined using reverse transcription-PCR. Rats showed a sustained decrease in PWL, associated with a prolonged immobility time after CCI. 4-MC reduced decreases in PWL and increased immobility time. 4-MC reduced increases in pERK immunoreactivity and decreases in BDNF mRNA expression in regions related to pain and the limbic system. Anti-BDNF blocked effects induced by 4-MC. We suggest that a lack of BDNF associated with activated extracellular signal-regulated kinase in the pain-emotion network may be involved in depression-like behavior during chronic pain. 4-MC ameliorates pain-emotion symptoms by inducing BDNF and normalizing pERK activities.

    Literature review for indocyanine green angiography and evaluate the role of indocyanine green angiogram (ICGA) in patients with posterior uveitis seen at a tertiary referral eye care centre. Detailed review of the literature on ICGA was performed. Retrospective review of medical records of patients with posterior uveitis and dual fundus and ICGA was done after institutional board approval. Eighteen patients (26 eyes) had serpiginous choroiditis out of which 12 patients had active choroiditis and six patients had healed choroiditis, six patients (12 eyes) had ampiginous choroiditis, six patients (12 eyes) had acute multifocal posterior placoid pigment epitheliopathy, eight patients (10 eyes) had multifocal choroiditis, four patients (eight eyes) had presumed ocular histoplasmosis syndrome, four patients (eight eyes) had presumed tuberculous choroiditis, two patients (four eyes) had multiple evanescent white dot syndrome and two patients (four eyes) had Vogt Koyanagi Harada (VKH) syndrome. The most characteristic feature noted on ICGA was the presence of different patterns of hypofluorescent dark spots, which were present at different stages of the angiogram. ICGA provides the clinician with a powerful adjunctive tool in choroidal inflammatory disorders. It is not meant to replace already proven modalities such as the fluorescein angiography, but it can provide additional information that is useful in establishing a more definitive diagnosis in inflammatory chorioretinal diseases associated with multiple spots. It still needs to be determined if ICGA can prove to be a follow up parameter to evaluate disease progression.

    Aims: To determine the levels of IgG class antibodies to recombinant heat shock protein 60 kDa of Yersinia enterocolitica (rHSP60Ye), Klebsiella pneumoniae (rHSP60Kp), Escherichia coli (rHSP60Ec), Shigella flexneri (rHSP60Sf), and Streptococcus pyogenes (rHSP60Sp) in the serum of patients with HLA-B27 associated acute anterior uveitis (HLA-B27 associated AAU), idiopathic acute anterior uveitis (idiopathic AAU), pars planitis, Vogt-Koyanagi-Harada (VKH), and healthy subjects. Methods: The genes that code for HSP60Ye, HSP60Kp, HSP60Ec, HSP60Sf, and HSP60Sp were cloned by PCR from genomic DNA. The rHSPs were purified by affinity using a Ni-NTA resin. The serum levels of IgG class antibodies to rHSP60s were determined by ELISA in patients with uveitis (n = 42) and in healthy subjects (n = 25). Results: The majority of patients with uveitis had higher levels of IgG class antibodies to rHSP60Ye compared with levels of healthy subjects (p = 0.01), although these differences were only observed in the HLA-B27 associated AAU (p = 0.005) and in pars planitis patients (p = 0.001). The levels of IgG antibodies to the rHSP60Kp, rHSP60Sf, rHSP60Ec, and rHSP60Sp were similar in patients with uveitis and in healthy subjects (p>0.05). Conclusion: The results suggest that HSP60Ye could be involved in the aetiology of HLA-B27 associated AAU and pars planitis. PMID:14736785

    Purpose. We aimed to investigate retinal and choroidal thickness in the eyes of patients with Fuchs' uveitis syndrome (FUS). Methods. Fifteen patients with unilateral FUS and 20 healthy control subjects were enrolled. Spectral domain optical coherence tomography (Spectralis HRA+OCT, 870 nm; Heidelberg Engineering, Heidelberg, Germany) was used to obtain retinal and choroidal thickness measurements. The retinal nerve fiber layer (RNFL) thickness, macular thickness, and choroidal thickness of the eyes with FUS were compared with the unaffected eye and the eyes of healthy control subjects. Results. The mean choroidal thickness at fovea and at each point within the horizontal nasal and temporal quadrants at 500 μm intervals to a distance of 1500 µm from the foveal center was significantly thinner in the affected eye of FUS patients compared with the unaffected eye of FUS patients or the eyes of healthy control subjects. However, there were no significant differences in RNFL or macular thickness between groups. Conclusions. Affected eyes in patients with FUS tend to have thinner choroids as compared to eyes of unaffected fellow eyes and healthy individuals, which might be a result of the chronic inflammation associated with the disease.

    This report documents a 47-year-old man who presented with back pain, uveitis and an elevated Westergren sedimentation rate. On biopsy, a paraspinal lesion showed a nonspecific chronic inflammatory cell infiltrate. The eye symptoms, after initially responding to immunosuppressive therapy, worsened and progressed to pain, resulting in an extirpation of the right eye. The histopathology of the excised eye showed an inflammatory pseudotumor marked by a lymphoplasmacytic infiltrate, areas of fibrosis, rare evidence of obliterative phlebitis and, focally, over 20 Immunoglobulin G4 (IgG4)-positive staining cells per high power microscopic field. IgG4-related ophthalmic disease is a relatively rare inflammatory lesion involving the eye and periorbital region. It is defined by a marked lymphoplasmacytic cell infiltrate, fibrosis obliterative phlebitis and increased IgG4 immunostaining (at least 10 cells per high power microscopic field in excised tissue). The entity is not unique to the eye, and has been described in other organs including the brain, endocrine organs, liver and kidney. The clinical presentation is often related to the location of the inflammatory infiltrates, and treatment involves the use of corticosteroids and other immunosuppressive agents. It is important to recognize IgG4-related ophthalmic disease because the condition appears to put patients at increased risk of developing lymphoma.

    Non-infectious uveitis is a potentially sight-threatening ocular disorder caused by chronic inflammation and its complications. Therapeutic success is limited by systemic adverse effects associated with long-term corticosteroid and immunomodulator use if topical medication is not sufficient to control the inflammation. We aimed to assess the efficacy and safety of adalimumab in patients with inactive, non-infectious uveitis controlled by systemic corticosteroids. We did this multicentre, double-masked, randomised, placebo-controlled phase 3 trial at 62 study sites in 21 countries in the USA, Canada, Europe, Israel, Australia, and Latin America. Patients (aged ≥18 years) with inactive, non-infectious intermediate, posterior, or panuveitic uveitis controlled by 10-35 mg/day of prednisone were randomly assigned (1:1), via an interactive voice and web response system with a block size of four, to receive either subcutaneous adalimumab (loading dose 80 mg; biweekly dose 40 mg) or placebo, with a mandatory prednisone taper from week 2. Randomisation was stratified by baseline immunosuppressant treatment. Sponsor personnel with direct oversight of the conduct and management of the study, investigators, study site personnel, and patients were masked to treatment allocation. The primary efficacy endpoint was time to treatment failure, a multicomponent endpoint encompassing new active inflammatory chorioretinal or inflammatory retinal vascular lesions, anterior chamber cell grade, vitreous haze grade, and visual acuity. Analysis was done in the intention-to-treat population. This trial is registered with ClinicalTrials.gov number NCT01124838. Between Aug 10, 2010, and May 14, 2015, we randomly assigned 229 patients to receive placebo (n=114) or adalimumab (n=115); 226 patients comprised the intention-to-treat population. Median follow-up time was 155 days (IQR 77-357) in the placebo group and 245 days (119-564) in the adalimumab group. Treatment failure occurred in 61 (55

    AIM To investigate the anti-inflammatory effect of an aqueous whole plant extract of Heliotropium indicum (HIE) on endotoxin-induced uveitis in New Zealand white rabbits. METHODS Clinical signs of uveitis including flares, iris hyperemia and miosis, were sought for and scored in 1.0 mg/kg lipopolysaccharide (LPS) -induced uveitic rabbits treated orally with HIE (30-300 mg/kg), prednisolone (30 mg/kg), or normal saline (10 mL/kg). The number of polymorphonuclear neutrophils infiltrating, the protein concentration, as well as levels of tumor necrosis factor-α (TNF-α), prostaglandin E2 (PGE2), and monocyte chemmoattrant protein-1 (MCP-1) in the aqueous humor after the various treatments were also determined. A histopathological study of the anterior uveal was performed. RESULTS The extract and prednisolone-treatment significantly reduced (P≤0.001) both the clinical scores of inflammation (1.0-1.8 compared to 4.40±0.40 in the normal saline-treated rabbits) and inflammatory cells infiltration. The level of protein, and the concentrations of TNF-α, PGE2 and MCP-1 in the aqueous humor were also significantly reduced (P≤0.001). Histopathological studies showed normal uveal morphology in the HIE and prednisolone-treated rabbits while normal saline-treated rabbits showed marked infiltration of inflammatory cells. CONCLUSION The HIE exhibits anti-inflammatory effect on LPS-induced uveitis possibly by reducing the production of pro-inflammatory mediators. PMID:27162723

    We present a surgical treatment for bladder reconstruction in a case of chronic vesicocutaneous radiation-induced fistula and reconstruction of the abdominal wall after resection of a liposarcoma in the rectus abdominis muscle. Fistulas are sequelae after radiotherapy. To regain bladder function and reconstitute abdominal wall stability, a microsurgical flap approach should be considered. A male patient underwent resection of a liposarcoma in the rectus abdominis muscle with adjuvant radiotherapy, suffering from a chronic vesicocutaneous fistula. A bipedicled combined latissimus dorsi and serratus anterior flap was carried out after resection of the fistula for reconstruction of the urine bladder and the abdominal wall. Ascending urethrography 4 weeks postoperatively showed no leakage. In the 4-month follow-up period, no signs of recurrence of the fistula or herniation occurred. A bipedicled flap allowed reconstruction of the urine bladder and the abdominal wall. Using non-irradiated, well-perfused intra-abdominal muscle tissue over the urine bladder prevented recurrence of the fistula.

    Uveitis, a group of conditions characterized by intraocular inflammation, is a major cause of sight loss in the working population. Most uveitis seen in Western countries is noninfectious and appears to be autoimmune or autoinflammatory in nature, requiring treatment with immunosuppressive and/or anti-inflammatory drugs. In this educational review, we outline the ideal characteristics of drugs for uveitis and review the data to support the use of current and emerging therapies in this context. It is crucial that we continue to develop new therapies for use in uveitis that aim to suppress disease activity, prevent accumulation of damage, and preserve visual function for patients with the minimum possible side effects.

    Current understanding of the role of oxidative stress in ocular inflammatory diseases indicates that antioxidant therapy may be important to optimize the treatment. Recently investigated antioxidant therapies for ocular inflammatory diseases include various vitamins, plant products and reactive oxygen species scavengers. Oxidative stress plays a causative role in both non-infectious and infectious uveitis complications, and novel strategies to diminish tissue damage and dysfunction with antioxidant therapy may ameliorate visual complications. Preclinical studies with experimental animals and cell culture demonstrate significance of anti-inflammatory effects of a number of promising antioxidant agents. Many of these antioxidants are under clinical trial for various inflammatory diseases other than uveitis such as cardiovascular, rheumatoid arthritis and cancer. Well planned interventional clinical studies of the ocular inflammation will be necessary to sufficiently investigate the potential medical benefits of antioxidant therapies for uveitis. This review summarizes the recent investigation of novel antioxidant agents for ocular inflammation, with selected studies focused on uveitis. PMID:21182473

    To describe particular iris precipitates in a series of five eyes from six patients with Fuchs uveitis (FU). Iris precipitates were noted by four independent examiners during routine physical examination of the angle by gonioscopy with Goldmann's three-mirror lens in patients with FU. The result was confirmed by examination, using the same method, of five other consecutive patients with FU and compared to 10 normal control eyes from five healthy individuals. Other causes of anterior uveitis were excluded. There were no iris precipitates in the healthy eyes. In eyes with FU, there were fluffy white iris precipitates, not visible by full-face examination or by classic slit-lamp examination. They were similar to keratic precipitates described in FU: starry, blurry and transparent with a tendency towards the white. Situated on the surface of the iris, they were visible only with the particular diffusion of the light from the gonioscopy's glass on the darkly pigmented iris of patients from North Africa. Fluffy white iris precipitates, seen in FU patients, appear to represent an additional clinical sign and may improve our diagnostic accuracy in this disease. Its visibility requires a specific technique during clinical examination. The validity of this new clinical sign based on this fact is yet to be determined.

    ABSTRACT Endotoxin-induced uveitis (EIU) in rodents is a model of acute Toll-like receptor 4 (TLR4)-mediated organ inflammation, and has been used to model human anterior uveitis, examine leukocyte trafficking and test novel anti-inflammatory therapeutics. Wider adoption has been limited by the requirement for manual, non-specific, cell-count scoring of histological sections from each eye as a measure of disease severity. Here, we describe a comprehensive and efficient technique that uses ocular dissection and multimodal tissue analysis. This allows matched disease scoring by multicolour flow cytometric analysis of the inflammatory infiltrate, protein analysis on ocular supernatants and qPCR on remnant tissues of the same eye. Dynamic changes in cell populations could be identified and mapped to chemokine and cytokine changes over the course of the model. To validate the technique, dose-responsive suppression of leukocyte infiltration by recombinant interleukin-10 was demonstrated, as well as selective suppression of the monocyte (CD11b+Ly6C+) infiltrate, in mice deficient for either Ccl2 or Ccr2. Optical coherence tomography (OCT) was used for the first time in this model to allow in vivo imaging of infiltrating vitreous cells, and correlated with CD11b+Ly6G+ counts to provide another unique measure of cell populations in the ocular tissue. Multimodal tissue analysis of EIU is proposed as a new standard to improve and broaden the application of this model. PMID:26794131

    A 62 year-old white female presented with a 10-year-history of slowly progressive spastic paraparesis, pain and dysesthesia in the lower limbs and sphincter disturbance. A few years after the onset of the neurologic symptoms she developped migratory arthritis with swelling of the knees and pain on palpation of knees and fingers, dry eyes, mouth and skin. Two months before admission she presented bilateral nongranulomatous anterior uveitis. Examination revealed spastic paraparesis with bilateral Babinski sign, a decreased sensation level below L3, decreased vibration sense in the lower extremities, and a postural tremor of the upper limbs. Laboratory work-up disclosed HTLV-I positive tests in the blood and cerebrospinal fluid (CSF), and a mild pleocytosis in the CSF with a normal protein content. Nerve conduction velocity studies were normal. The present case shows the association of uveitis, arthritis and Sjögren's syndrome in a patient with tropical spastic paraparesis/human T-cell lymphotropic virus type I (HTLV-I) associated myelopathy (TSP/HAM), and illustrates the wide spectrum of clinical manifestations which may accompany this infection with this virus.

    We report a 17-year-old male patient with tubulointerstitial nephritis and uveitis (TINU) associated with hyperthyroidism. He presented with a 2-month history of fatigue, loss of appetite, low-grade fever, and a 12-kg weight loss when he was admitted to our hospital. He had iritis, which was complicated by fibrin in the anterior chamber, diagnosed by slit-lamp examination. On laboratory examinations, deteriorated renal function (blood urea nitrogen level was 25.9 mg/dl and creatinine level was 2.82 mg/dl) and elevated urinary levels of N-acetyl-beta-D-glucosaminidase (33.1 U/l) and beta2-microglobulin (78,600 microg/l) were observed. Serum thyroid-stimulating hormone (TSH) was undetectable, at less than 0.01 microIU/ml, and free triiodothyronine and free thyroxine were elevated, up to 5.23 pg/ml and 2.85 ng/dl, respectively. The titers of antithyroglobulin and antithyroid microsomal and TSH-receptor antibodies were not elevated. Abdominal and thyroidal ultrasonography showed evident bilateral enlargement of the kidneys and diffuse enlargement of the thyroid gland. Iodine-123 scintigraphy showed low uptake in the thyroid gland. The biopsied renal specimen showed mild edema and severe diffuse infiltration of mononuclear cells and few eosinophils in the interstitium, without any glomerular or vascular abnormalities. Based on the clinical features and pathological findings, a diagnosis of TINU syndrome with associated hyperthyroidism was made. Treatment was started with 30 mg/day of prednisolone. The iritis disappeared, and the patient's clinical status improved remarkably. This case suggests the possibility of thyroid dysfunction in some patients with TINU syndrome, and we believe thyroid function should be measured in all TINU patients. Moreover, histopathological diagnosis of the thyroid glands before treatment is necessary for TINU patients with thyroid dysfunction.

    Objective The role of cortical drive in stroke recovery for the lower extremity remains ambiguous. The purpose of this study was to investigate the relationship between cortical drive and gait speed in a group of stroke survivors. Methods Eighteen individuals with stroke were dichotomized into fast or slow walking groups. Transcranial magnetic stimulation (TMS) was used to collect motor evoked potentials (MEPs) from the tibialis anterior of each lower extremity during rest, paretic muscle contractions, and nonparetic muscle contractions. An asymmetry-index (AI) was calculated using motor thresholds and compared between groups. The average MEP of the paretic leg during TMS at maximal intensity (MEP100) for each condition was compared within and between groups. Results A significant positive correlation was found between AI and walking speed. Slow-walkers had greater MEP100s during the nonparetic contraction than during the paretic contraction or rest conditions. In contrast, fast-walkers had greatest MEP100s during the paretic contraction. Conclusions Alterations in the balance of corticomotor excitability occur in the lower extremity of individuals with poor motor recovery post-stroke. This atypical cortical drive is dependent on activation of the unaffected hemisphere and contraction of the nonparetic leg. Significance Understanding mechanisms underlying function can help to identify specific patient deficits that impair function. PMID:26142877

    High-frequency stimulation (HFS) of the anterior nucleus of thalamus (ANT) is a new and alternative option for the treatment of intractable epilepsy. However, the responder rate is relatively low. The present study was designed to determine the effect of low-frequency stimulation (LFS) in ANT on chronic spontaneous recurrent seizures and related pathological pattern in intra-hippocampal kainate mouse model. We found that LFS (1 Hz, 100 μs, 300 μA), but not HFS (100 Hz, 100 μs, 30 μA), in bilateral ANT significantly decreased the frequency of spontaneous recurrent seizures, either non-convulsive focal seizures or tonic-clonic generalized seizures. The anti-epileptic effect persisted for one week after LFS cessation, which manifested as a long-term inhibition of the frequency of seizures with short (20-60 s) and intermediate duration (60-120 s). Meanwhile, LFS decreased the frequency of high-frequency oscillations (HFOs) and interictal spikes, two indicators of seizure severity, whereas HFS increased the HFO frequency. Furthermore, LFS decreased the power of the delta band and increased the power of the gamma band of hippocampal background EEG. In addition, LFS, but not HFS, improved the performance of chronic epileptic mice in objection-location task, novel objection recognition and freezing test. These results provide the first evidence that LFS in ANT alleviates kainate-induced chronic epilepsy and cognitive impairment, which may be related to the modulation of the hippocampal EEG rhythm. This may be of great therapeutic significance for clinical treatment of epilepsy with deep brain stimulation. Copyright © 2015 Elsevier Inc. All rights reserved.

    AIM To compare the safety and effectiveness of phacotrabeculectomy versus sequential surgery in chronic angle-closure glaucoma (CACG) with coexisting cataract. METHODS One hundred and sixty-two CACG patients (162 eyes) were retrospectively analyzed. Of them, 87 patients (87 eyes) in group A had underwent phacotrabeculectomy with intraocular lens (IOL) implantation, and 75 patients (75 eyes) in group B had underwent sequential surgery with IOL implanted. Best-corrected visual acuity (BCVA), intraocular pressure (IOP), complications and anterior chamber angle (ACA) were measured. RESULTS Demographic characteristics of the two groups were similar. A mean follow-up period was 15±6mo (range 13 to 24mo), a mean IOP of 16.61±6.43 mm Hg in group A and 15.80±5.35 mm Hg in group B (P=0.84) at the last follow up. The Kaplan-Meier analysis revealed that the cumulative probability of success in both groups was similar (P=0.61). Anterior uveitis and hypotony were the most common complications in group A, whereas group B experienced shallow anterior chamber with trabeculectomy. With the exception of anterior uveitis, no complications occurred to 11 trabeculectomized eyes. All postoperative measurements of anterior chamber showed statistically significant differences in each group according to the preoperative data (P<0.05). However, fewer changes occurred in group B than in group A. CONCLUSION Phacotrabeculectomy and sequential surgery exhibit similar IOP reduction, visual recovery, and complications when treating CACG patients with cataract. However, for a wider ACA, phacotrabeculectomy has demonstrated higher effectiveness than sequential surgery. PMID:27275422

    Purpose To report our experience with dexamethasone 0.7 mg sustained-release intravitreal implant (Ozurdex®; Allergan, Inc, Irvine, CA) in noninfectious posterior uveitis. Methods A retrospective chart review of patients with noninfectious uveitis treated with sustained-release dexamethasone 0.7 mg intravitreal implant was performed. Complete ophthalmic examination including signs of inflammatory activity, visual acuity, fundus photography, fluorescein angiography, optical coherence tomography, and tolerability of the implant were assessed. Results Six eyes of 4 consecutive patients treated with a total of 8 dexamethasone 0.7 mg sustained-release intravitreal implants for posterior noninfectious uveitis were included. Two patients presented with unilateral idiopathic posterior uveitis; 2 patients had bilateral posterior uveitis, one secondary to sarcoidosis and the other to Vogt-Koyanagi-Harada syndrome. All eyes showed clinical and angiographic evidence of decreased inflammation following implant placement. Mean follow-up time post-injection was 5.25 months. Four eyes received 1 and 2 eyes received 2 Ozurdex implants during the follow-up period. The duration of effect of the implant was 3 to 4 months. No serious ocular or systemic adverse events were noted during the follow-up period. Conclusions In patients with noninfectious posterior uveitis, sustained-release dexamethasone 0.7 mg intravitreal implant may be an effective treatment option for controlling intraocular inflammation.

    Commonly is accepted that a non-vital tooth has a higher risk of root fracture but there is a relatively little knowledge about the specific biomechanical behavior of non-vital frontal teeth with chronic apical periodontitis. The aim of our study was to evaluate the deformation and tensile generated in these teeth while vertically loading them because it is crucial to assess the moment when the absorbed occlusal forces exceed the elasticity of root dentine. Using the method of finite-element analysis, we highlighted the distribution patterns of the compressive and tension tensile, as well as their concentration areas. The vertical forces of 100 N generate deformations of no clinical risk in teeth with chronic apical periodontitis. The tensile developed in these teeth are higher than those in the vital teeth are but do not exceed the value of the elastic modulus of the radicular dentin. By increasing the force to 300 N occur elastic deformations, which cannot be neglected anymore. Even so, the 300 N forces do not generate deformations of the alveolar bone. The highest tensile at loading with 300 N was generated in vertical direction but in the cervical area of the tooth also developed tensile in lingual and mesiodistal direction that must be taken into consideration because they are near the risk limit of the elasticity modulus. The crack lines or fractures can appear both in case of excessive or even usual but accumulative occlusal forces that gradually alter the mechanical resistance of the tooth.

    Giant cell arteritis, also known as temporal arteritis, is the most common primary vasculitis affecting the nervous system. Early recognition of this treatable condition is essential to avoid potentially devastating complications. Giant cell arteritis occurs in adults older than 50 years and affects large and medium-sized arteries, especially the external and internal carotid arteries and their branches. Severe inflammation of the vessel wall may result in obstruction of the lumen and end-organ ischemia. Typical giant cell arteritis symptoms include headache, scalp tenderness, jaw claudication, and polymyalgia rheumatica. Ischemia induced by the arteritis can lead to blindness. Herein, we describe a rare case of giant cell arteritis in a patient who initially presented with uveitis, thus eluding timely diagnosis and prompt therapy.

    Equine recurrent uveitis (ERU) has always been and still is an important disease with a significant impact on the horse industry in Europe, with a prevalence of 8-10%. The need to understand and manage the disease has spurred the development of veterinary ophthalmology in general, although the aetiology of the disease remains the subject of intense discussion. It is most probably an autoimmune disease triggered, at least in Europe, in the majority of cases by Leptospira spp. The therapy of ERU has evolved over the centuries from various methods of bloodletting to rational medical therapy using mydriatics and steroidal and nonsteroidal anti-inflammatory drugs, to surgical therapies, such as vitrectomy or implantation of cyclosporin-releasing devices. In Europe, pars plana vitrectomy in horses testing positive for Leptospira spp. appears to be the most successful form of therapy at the present time.

    Previously we have detected the occurrence of retinal lipid peroxidation initiated by phagocyte-derived oxygen radicals in experimental autoimmune uveitis (EAU). In the current studies, the confirmation of inflammation-mediated lipid peroxidation was proceeded further to include measurement of multiple parameters, including conjugated dienes, ketodienes, thiobarbituric acid reactive substances and fluorescent chromolipids. The assay for myeloperoxidase, a measure for the number of polymorphonuclear leukocytes in the inflammatory sites was also carried out. The levels of all these parameters were followed through the course of EAU development. The sequential evaluation of histologic changes using both light and electron microscopy was also carried out and the results were correlated with lipid peroxidation indices. These data suggest that the retinal lipid peroxidation plays a causative role in the subsequent retinal degeneration.

    Despite extensive clinical research, the etiology of equine recurrent uveitis (ERU) is still unknown. After an immunologic pathogenesis was established in recurrent uveitis in humans, a similar pathogenic mechanism was assumed to exist in ERU. To investigate whether immunopathologic mechanisms are involved in ERU, 20 eyes of 15 horses with ERU were examined immunohistochemically with a T cell marker, B cell marker, and anti-major histocompatibility complex (MHC) class II antibodies. Twenty-six eyes of 20 horses were used for investigation of MHC class II antigen expression in normal equine eyes. In 18 eyes of 14 horses, the number of T cells in the inflammatory cell population within the uvea was assessed. In 16/18 eyes (89%), the T lymphocyte fraction was > 70%. This cell population was distributed mostly in a diffuse manner throughout the uvea and also within the mantle zone of follicular lymphocytic aggregates. Foci of B lymphocytes could be found within the center of follicular aggregates in three eyes. The expression of MHC class II antigen on resident ocular cells was evaluated in 10 eyes of six horses with ERU. An increase of MHC class II antigen expression in the trabecular meshwork and on the nonpigmented ciliary epithelium was noted as was a deviant expression on proliferating Müller cells and retinal pigment epithelial cells. The predominance of T cells in the inflammatory infiltrates supports the central role of a cell-mediated immune response. Furthermore, the observation of a deviant MHC class II expression on resident ocular cells suggests that aberrant immune regulation may play a role in the pathogenesis of ERU.

    To assess the short-term outcomes of the arthroscopic subscapularis augmentation (ASA) technique, consisting of a tenodesis of the upper third of the subscapularis tendon and a Bankart repair, and its effect on shoulder external rotation. Patients selected for this study were involved in contact sports, with a history of traumatic recurrent shoulder dislocations and a minimum of 2-year follow-up. Inclusion criteria were patients with glenoid bone loss (GBL) ranging from 5% to 25%, anterior capsular deficiency, and Hill-Sachs lesion who underwent ASA technique. Exclusion criteria were GBL >25%, multidirectional instability, preexisting osteoarthritis, and overhead sports activities. Visual analog scale (VAS) scale for pain, Rowe score, and American Shoulder and Elbow Surgeons (ASES) scores were used to assess results. Loss of shoulder external rotation was measured with the arm at the side (ER1 position) or 90° in abduction (ER2 position). Analysis of variance and Fisher tests were used for data evaluation. Significance was established at P ≤ .05. One hundred ten patients (84 men and 26 women, mean age 27 years) were evaluated with a mean follow-up of 40.5 months (range: 24 to 65 months). In 98 patients, a Hill-Sachs lesion was observed and in 57 patients a capsular deficiency was present. Three patients (2.7%) had a traumatic redislocation. At final follow-up, the mean scores were as follows: VAS scale decreased from a mean of 3.5 to 0.5 (P = .015), Rowe score increased from 57.4 to 95.3 (P = .035), and ASES score increased from 66.5 to 96.5 (P = .021). The mean deficit of external rotation was 8° ± 2.5° in the ER1 position and 4° ± 1.5° in the ER2 position. The ASA procedure has been shown to be effective in restoring joint stability in patients practicing sports, affected by chronic anterior shoulder instability associated with anterior GBL (<25%), capsular deficiency, and Hill-Sachs lesions, with mild restriction of external rotation.

    Experimental autoimmune uveitis, a well-established model for human uveitis, is similar to human uveitis in many pathological features. Studies concerning the mechanisms of experimental autoimmune uveitis would cast a light on the pathogenesis of human uveitis as well as the search for more effective therapeutic agents. The cellular components of innate immunity include natural killer cells, gamma delta T lymphocytes, antigen-presenting dendritic cells, phagocytic macrophages, and granulocytes. It is believed that T cells are central in the generation of human uveitis. It has already become clear that CD4(+) effecter cells that predominantly produce interleukin-17 (the so-called Th17 cells) may play an important role in uveitis. In addition, the occurrence and recurrence of uveitis depends on a complex interplay between the elements of innate and adaptive immunity.

  3. Outcome of a Specific Compartment Fasciotomy Versus a Complete Compartment Fasciotomy of the Leg in One Patient With Bilateral Anterior Chronic Exertional Compartment Syndrome: A Case Report.

    2016-01-01

    Chronic exertional compartment syndrome of the leg is a debilitating lower extremity condition in which increased intracompartmental pressure impedes blood flow to the involved compartments of the distal lower extremity, resulting in ischemia and pain. Owing to the lack of success with conservative management, most surgeons perform complete release fasciotomy as the preferred method of fasciotomy to avoid an unsuccessful release or outcome. Studies have been performed regarding the outcomes of complete compartmental release versus specific compartmental release, but no study has been performed comparing complete fasciotomy and compartment-specific fasciotomy in a single patient. The purpose of the present case report was to compare the efficacy of a complete fasciotomy versus a specific fasciotomy in 1 patient with properly diagnosed bilateral anterior compartment chronic exertional compartment syndrome with an 18-month follow-up period. The Lower Extremity Functional Scale and both subscales of the Foot and Ankle Ability Measure were administered to assess the functional outcomes. Circumferential measurements and range of motion photographs were taken to compare the objective data throughout the recovery process. In general, the range of motion, circumferential measurements, and functional outcome measure scores were better for the specific compartmental fasciotomy leg than for the complete fasciotomy leg during the recovery period. The overall functional outcomes were the same for both surgical approaches, with the specific fasciotomy leg returning to baseline function 13 to 23 days before the complete fasciotomy leg. The outcomes remained unchanged 18 months after surgery. Copyright © 2015 American College of Foot and Ankle Surgeons. Published by Elsevier Inc. All rights reserved.

    Toxic reactions (uveitis, arthritis and leucopenia) of Rifabutin at normal doses should always be considered because of pharmacokinetic interactions with other drugs (e.g. the protease inhibitors). This case demonstrates that this kind of uveitis is clinically significant as the diagnosis of uveitis, particularly hypopyon uveitis, in an immunocompromised patient generally mandates extensive systemic diagnostic evaluation, as well as intensive ophthalmic and systemic monitoring and therapy.

    Purpose To investigate the contribution of the gut microbiota to the pathogenesis of uveitis. Methods Experimental autoimmune uveitis (EAU) in B10.RIII mice was induced using interphotoreceptor binding protein peptide. Mice were treated with oral or intraperitoneal (IP) antibiotics. Effector (Teff) and regulatory (Treg) T lymphocytes were identified using flow cytometry; 16S rRNA gene sequencing and qPCR were performed on gastrointestinal (GI) contents. Results Broad-spectrum (four antibiotics given simultaneously) oral, but not IP, antibiotics reduced mean uveitis clinical scores significantly compared with water-treated animals (0.5 vs. 3.0, P < 0.0001 for oral; 3.4 vs. 3.4, P > 0.99 for IP). Both oral metronidazole (P = 0.02) and vancomycin (P < 0.0001) alone decreased inflammation, whereas neomycin (P = 0.7) and ampicillin (P = 0.4) did not change mean uveitis scores. Oral broad-spectrum antibiotics increased Tregs in the GI lamina propria of EAU animals at 1 week, and in extraintestinal lymphoid tissues later, whereas Teff and inflammatory cytokines were reduced. 16S sequencing of GI contents revealed altered microbiota in immunized mice compared with nonimmunized mice, and microbial diversity clustering in EAU mice treated with uveitis-protective antibiotics. Experimental autoimmune uveitis mice also demonstrated gut microbial diversity clustering associated with clinical score severity. Conclusions Oral antibiotics modulate the severity of inducible EAU by increasing Tregs in the gut and extraintestinal tissues, as well as decreasing effector T cells and cytokines. 16S sequencing suggests that there may be protective and, conversely, potentially uveitogenic, gut microbiota. These findings may lead to a better understanding of how uveitis can be treated or prevented by modulating the gut microbiome. PMID:27415793

    Non-infectious uveitis (NIU) leads to severe visual impairment, potentially impacting on health-related quality of life (QoL). To investigate the impact of NIU on QoL. Eighty NIU patients and 23 healthy controls completed the 36-item Short-Form Health Survey (SF)-36. The SF-36 values were statistically analyzed to evaluate differences between patients and healthy controls and to identify correlations between SF-36 subscores and clinical/demographic data. NIU patients showed a decrease in the physical component summary score (P < 0.0001) compared to healthy controls, while no difference was highlighted in the mental component summary score (P = 0.97). NIU patients showed a decrease in physical functioning (P = 0.008), role-physical (P = 0.003), bodily pain (P = 0.0001), general health (P < 0.0001), and social functioning (P = 0.01). Physical functioning was lower in patients with acute anterior uveitis (AAU) than in those with panuveitis (P = 0.003). No differences were found between patients with bilateral or unilateral NIU, isolated NIU, or NIU associated with systemic diseases and with or without ocular activity. No correlations were identified between best-corrected visual acuity and SF-36 subscores. Physical functioning (P = 0.02), bodily pain (P = 0.004), and social functioning (P = 0.02) were reduced in males versus females. QoL is impaired in individuals with NIU, particularly in the physical domains, general health, and social functioning. AAU affects physical functioning more than panuveitis. NIU seems to affect per se QoL disregarding inflammatory activity, visual impairment, and presence of associated systemic diseases.

    Genetic variations have been identified in the genome of varicella-zoster virus (VZV) strains using vesicle fluid, varicella scabs and throat swab samples. We report a rare case of VZV-associated uveitis with severe hyphema, which was immediately diagnosed by polymerase chain reaction (PCR) using the aqueous humor, in which we were able to analyze the VZV genotype for the first time. A 16-year-old Japanese boy was referred to our hospital with a 20-day history of unilateral anterior uveitis and 11-day history of hyphema. At presentation, details of the iris, the iridocorneal angle, and the fundus were not visible due to the severe hyphema. Serum anti-VZV IgG and anti-VZV IgM were elevated, and 1.61 × 10(9) copies/mL of VZV-DNA were detected by real-time PCR using the aqueous humor. As there were no eruptions on his face or body, we diagnosed zoster sine herpete and started intravenous administration of prednisolone and acyclovir. The hyphema completely disappeared 2 weeks after presentation, while sectorial iris atrophy and mild periphlebitis of the fundus became gradually apparent. Anterior inflammation and periphlebitis gradually improved and VZV-DNA in the aqueous humor was reduced to 1.02 × 10(6) copies/mL at 4 weeks after presentation. Examination by slit lamp microscope revealed no inflammation after 5 months, and VZV-DNA could no longer be detected in the aqueous humor. Serum anti-VZV IgG and anti-VZV IgM also showed a gradual decrease along with improvement in ocular inflammation. The genetic analysis of multiple open reading frames and the R5 variable repeat region in the VZV genes, using DNA extracted from the aqueous humor at presentation, showed that the isolate was a wild-type clade 2 VZV strain (prevalent in Japan and surrounding countries) with R5A allele and one SNP unique to clade 1 (both are major types in Europe and North America). VZV-associated uveitis may develop hyphema that obscures ocular inflammation, thus PCR analysis using the

    Patient: Male, 54 Final Diagnosis: Old myocardial infarction Symptoms: Lower extremity swelling • respiratory distress Medication: — Clinical Procedure: Success Specialty: Cardiology Objective: Unusual setting of medical care Background: Success rates for treatment of chronic total occlusion (CTO) have dramatically improved in recent years with the development of new CTO guidewires and development of new techniques such as the retrograde approach. In the antegrade approach, a guidewire is occasionally passed through a side branch despite successful wire crossing of the CTO lesion. In order to pass a wire through the main artery, there are a few side branch techniques such as a reverse wire technique. Case Report: A 54-year-old man with symptoms of heart failure was admitted to our hospital. Coronary angiography showed CTO of the proximal left anterior descending artery. Percutaneous coronary intervention with an antegrade approach was started. We succeeded in passing the wire through a side branch but not the main artery. Unfortunately, a reverse wire technique failed in this case. Next, the wire passed through a side branch was exchanged with the Soutenir CV, and a retrograde approach was started. The wire crossing from retrograde was entwined around the Soutenir CV. After that, the retrograde wire was snared and guided to the antegrade guiding catheter, which resulted in successful wiring into the main artery easily. Conclusions: The side branch technique using the Soutenir CV may be an effective strategy in some cases. PMID:28082733

    Patient: Female, 44 Final Diagnosis: Tubulointerstitial nephritis • uveitis syndrome Symptoms: — Medication: Loxoprofen sodium hydrate Clinical Procedure: Renal biopsy Specialty: Nephrology Objective: Rare disease Background: Although TINU syndrome is characterized by idiopathic TIN with bilateral anterior uveitis, few reports have provided a comprehensive summary of the features of this disorder. Previous reports have suggested that many Japanese patients had HLA-A2 and -A24 (7), but there is no evidence. Case Report: A 44-year-old female was referred to our hospital due to renal dysfunction in March 2012. After admission, her symptoms improved spontaneously without medication within 2 weeks. In the outpatient clinic, she was diagnosed with idiopathic bilateral anterior uveitis in May, and her renal dysfunction relapsed in November. A renal biopsy showed diffuse TIN. We made a diagnosis of TINU syndrome because we could not explain the origin, and treated her with a systemic corticosteroid. Her renal function and ocular symptoms have been improving. The patient had HLA-A24, -B7, -DR1, -C*07: 02 and -DQB1*05: 01: 01. We collected 102 Japanese cases in PubMed, Ovid MEDLINE, and the Japanese Medical Abstracts Society and compared our case with the previous cases. Conclusions: This disorder affects primarily young females (median age, 14 years), and the most common symptom is fever (44/102 cases). We conducted a statistical analysis using contingency table and Pearson’s chi-square test, for HLA-A2 and A24, and calculated the odds ratio (OR). There are no significant differences (A2 was present in 7/22 cases and in 19/50 controls, p value (P) 0.61, OR 0.76 (95% confidence interval (CI)) 0.27–2.2; A24 was present in 10/22 cases and in 33/50 controls, P 0.10, OR 0.43, CI 0.16–1.2).

    Leptospirosis is a zoonotic disease that is highly prevalent in tropical countries; uveitis is one of the manifestations of leptospirosis. The leptospiral aetiology of uveitis is difficult to predict because of overlapping clinical symptoms with uveitis due to other causes. The objective of this study was to evaluate the leptospiral haemin-binding protein HbpA as a diagnostic antigen for the serodiagnosis of leptospiral uveitis. Serum samples from patients, clinically diagnosed with leptospiral uveitis, were tested by ELISA for anti-HbpA antibodies and compared against the 'gold standard' microscopic agglutination test (MAT). Non-leptospiral uveitis and normal healthy individuals were used as controls. A total of 60 serum samples from patients suffering from leptospiral uveitis were studied, obtained from Aravind Eye Hospital, Madurai. Anti-HbpA IgG antibodies were detected in 92 % of patients clinically diagnosed with leptospiral uveitis, indicating that it is more sensitive than MAT, which had a seropositivity of only 50 %, and better than the commercially available Pan Bio IgM ELISA (81 %). The mean anti-HbpA antibody titre was significantly higher in leptospiral uveitis patients compared with controls (P<0.05). The antigen showed negligible cross-reactivity with non-leptospiral uveitis samples and cataract controls. We conclude that HbpA IgG ELISA identified cases of uveitis with leptospirosis aetiology and proved to be useful in differentiating them from other forms of uveitis.

    A 1-year-old female spayed mixed-breed dog was presented for evaluation of acute onset of lethargy and blepharospasm OD. Slit-lamp biomicroscopy revealed a segmented larva embedded in the inferonasal iris. Moderate anterior uveitis was present. After pharmacologic dilation, mild vitreal hemorrhage and chorioretinal migration tracks were identified. The dog was treated empirically for uveitis for 5 days, after which a keratotomy and larval foreign body extraction was performed. The dog recovered uneventfully from intraocular surgery and remained visual and comfortable. Parasite evaluation confirmed the larva to be a Cuterebra sp. To the authors' knowledge, this is the first report of canine ophthalmomyiasis interna anterior, and the first report of successful surgical removal from the anterior segment in a dog with preservation of vision.

    Equine recurrent uveitis (ERU) is a leading cause of vision loss in horses. To assess the prognosis and impact of ERU on affected horses and their owners by evaluating the signalment, treatment and outcome (including the loss of use, vision assessment and economic loss). Retrospective impact study. Medical records of horses presenting to the North Carolina State University Veterinary Health Complex (NCSU-VHC) with ERU between 1999 and 2014 were reviewed. Signalment, clinical signs, ophthalmic examination findings, treatments and outcomes were evaluated. Owner questionnaires were completed regarding vision, job/role, monetary value, diagnostic and treatment costs, concurrent illness and outcomes. Records of 224 horses (338 eyes) with ERU were reviewed. There was an overrepresentation of Appaloosas (54; 24.1%), Hanoverians (11; 4.9%) and other Warmbloods (13; 5.8%). Ninety-six eyes (28.4%) were diagnosed as blind and 38 eyes (11.2%) with glaucoma on initial evaluation. Leptospirosis titres of serum and/or aqueous humour were obtained in 88 horses and were positive in 40 horses (45.5%), with L. pomona being the most frequently isolated serovar. Globe loss at the NCSU-VHC occurred in 41 ERU eyes (12.1% of total). Owner questionnaires were evaluated in 194 horses (86.6%) and 91 horses (46.9%) were reported blind in the affected eye(s). Fifty-seven horses (29.4%) did not return to their previous role, while 61 (31.4%) performed at a reduced level. Equine recurrent uveitis decreased the monetary value of 164 horses. Twenty-nine horses (14.9%) were euthanised and 37 (19.1%) underwent change in ownership as a direct result of ERU. The impact of ERU is attributed to the high frequency of blindness, globe loss and loss of function. Euthanasia and change of ownership are common sequelae to the progressive nature of ERU. These factors, along with financial costs of the disease, have a significant impact on affected horses and their owners. © 2015 EVJ Ltd.

    We report successful treatment of syphilitic uveitis in a case series of three Human immunodeficiency virus (HIV)-positive patients at Malaysia's Selayang Hospital eye clinic. All three patients with syphilitic uveitis were male, aged from 23 to 35 years old, with a history of high-risk behaviors. Of the patients, two presented with blurring of vision and only one patient presented with floaters in the affected eye. Ocular examination revealed intermediate uveitis (case 1 and case 3) and panuveitis (case 2). Each patient showed a high Venereal Disease Research Laboratory (VDRL) titer at presentation and they were also newly diagnosed as HIV positive with variable CD4 counts. All three patients responded well to a neurosyphilis regimen of intravenous penicillin G. At 3 months posttreatment, there was reduction in VDRL titer with improvement of vision in the affected eye. Diagnosis of syphilis needs to be ruled out in all cases of uveitis. All syphilitic uveitis cases should have HIV screening and vice versa, as syphilis is one of the most common infectious diseases associated with HIV-positive patients. Early detection and treatment are important for a good visual outcome.

    Uveitis can be a sight-threatening eye disease with significant morbidity. Corticosteroids remain the mainstay of treatment of uveitis and provide an effective treatment against ocular inflammation. However, the various modes available for corticosteroid drug delivery can carry significant ocular and systemic side effects which can limit their use in the treatment of uveitis. In an effort to avoid the damage to ocular structures that can ensue with recurrent episodes of ocular inflammation, the side effects associated with systemic steroids, and the need for repeated administration of both topical and locally injected corticosteroids, sustained-release intraocular corticosteroid implants have been developed. The dexamethasone (DEX) drug delivery system (Ozurdex®; Allergan Inc, Irvine, CA), is a biodegradable intravitreal implant. This implant has been shown to be effective in the treatment of macular edema and noninfectious posterior uveitis and has been approved by the FDA for these entities. This review will highlight the current methods available for corticosteroid delivery to the eye with a particular emphasis on the DEX intravitreal implant and the evidence currently available for its use in noninfectious uveitis.

    Recurrent uveitis as a sequela to Leptospira infection is the most common infectious cause of blindness and impaired vision of horses worldwide. Leptospiral proteins expressed during prolonged survival in the eyes of horses with lesions of chronic uveitis were identified by screening a phage library of Leptospira interrogans DNA fragments with eye fluids from uveitic horses. Inserts of reactive phages encoded several known leptospiral proteins and two novel putative lipoproteins, LruA and LruB. LruA was intrinsically labeled during incubation of L. interrogans in medium containing [14C]palmitic acid, confirming that it is a lipoprotein. lruA and lruB were detected by Southern blotting in infectious Leptospira interrogans but not in nonpathogenic Leptospira biflexa. Fractionation data from cultured Leptospira indicate that LruA and LruB are localized in the inner membrane. Uveitic eye fluids contained significantly higher levels of immunoglobulin A (IgA) and IgG specific for each protein than did companion sera, indicating strong local antibody responses. Moreover, LruA- and LruB-specific antisera reacted with equine ocular components, suggesting an immunopathogenic role in leptospiral uveitis. PMID:16239521

    The main objective of this 1.5-year prospective study was to evaluate the value of T-SPOT®.TB as compared to the tuberculin skin test (TST) for the first-line assessment of uveitis. A total of 108 consecutive non-immunocompromised patients with acute or chronic uveitis, including 92/108 (85.2%) with previous BCG vaccination, underwent a general examination, a TST, and a T-SPOT.TB test (Oxford Immunotec; Oxford, UK), blood and serological tests, and chest imaging. Concordance between tests was assessed using kappa coefficients. The performance of binary classification tests was evaluated with sensitivity, specificity, and likelihood ratios. The results of the TST and the T-SPOT.TB test differed significantly (55.5% versus 29.6% positivity, P < 0.001), with a low concordance between the two tests (κ = 0.362, P = 0.001). The sensitivity of the TST was 100% (diagnosis of suspected tuberculous uveitis included a positive TST), but its specificity was only 53.3%. The sensitivity and the specificity of the T-SPOT.TB test were 94.4% and 83.3%, respectively. The positive and negative likelihood ratios of the T-SPOT.TB test were 5.67 and 0.07, respectively. In uveitis patients with frequent previous BCG vaccination, the T-SPOT.TB test is more specific than the TST and therefore allows more accurate selection of patients requiring extensive investigations to rule out TB diagnosis.

    Uveitis is an important cause of vision loss worldwide due to its sight-threatening complications, especially cystoid macular edema, as well as choroidal neovascularization, macular ischemia, cataract, and glaucoma. Systemic corticosteroids are the mainstay of therapy for noninfectious posterior uveitis; however, various systemic side effects can occur. Intravitreal medication achieves a therapeutic level in the vitreous while minimizing systemic complications and is thus used as an exciting alternative. Corticosteroids, antivascular endothelial growth factors, immunomodulators such as methotrexate and sirolimus, and nonsteroidal anti-inflammatory drugs are currently available for intravitreal therapy. This article reviews the existing literature for efficacy and safety of these various options for intravitreal drug therapy for the management of noninfectious uveitis (mainly intermediate, posterior, and panuveitis).

    Purpose. Application of anterior segment optical coherence (AS-OCT) in pediatric ophthalmology. Methods. Retrospective clinical study case series of 26 eyes of 19 pediatric patients throughout a 21-month period, presenting anterior segment pathologies, were submitted to AS-OCT examination (OCT Visante, 1310 nm, Zeiss), noncontact technique, no sedation requirement. Results. AS-OCT images were obtained from 19 patients (range: 2 months to 12 years). Clinical diagnosis of anterior segment abnormalities included cornea disease (n = 7), congenital anterior segment conditions (n = 10), ocular trauma (n = 1), anterior segment surgeries (n = 2), iridocorneal angle abnormalities (n = 4), intermediate uveitis (n = 2). The most common OCT findings were corneal hyperreflectivity and thickening (n = 15), shallow anterior chamber with iris-lens diaphragm anterior displacement (n = 4), atypical corneal curvature (n = 4), corneal thinning (n = 4), peripheral synechiae with angle closure (n = 3), increased anterior chamber depth (n = 2), and proximal portion of glaucoma drainage tube (n = 2). Conclusion. In the present study, noncontact AS-OCT demonstrated to be a feasible technique to evaluate the anterior segment providing anatomic details and useful to clarify diagnosis in the pediatric population.

    Purpose Inflammation generates changes in the protein constituents of the aqueous humor. Proteins that change in multiple models of uveitis may be good biomarkers of disease or targets for therapeutic intervention. The present study was conducted to identify differentially-expressed proteins in the inflamed aqueous humor. Methods Two models of uveitis were induced in Lewis rats: experimental autoimmune uveitis (EAU) and primed mycobacterial uveitis (PMU). Differential gel electrophoresis was used to compare naïve and inflamed aqueous humor. Differentially-expressed proteins were separated by using 2-D gel electrophoresis and excised for identification with matrix-assisted laser desorption/ionization–time of flight (MALDI-TOF). Expression of select proteins was verified by Western blot analysis in both the aqueous and vitreous. Results The inflamed aqueous from both models demonstrated an increase in total protein concentration when compared to naïve aqueous. Calprotectin, a heterodimer of S100A8 and S100A9, was increased in the aqueous in both PMU and EAU. In the vitreous, S100A8 and S100A9 were preferentially elevated in PMU. Apolipoprotein E was elevated in the aqueous of both uveitis models but was preferentially elevated in EAU. Beta-B2–crystallin levels decreased in the aqueous and vitreous of EAU but not PMU. Conclusions The proinflammatory molecules S100A8 and S100A9 were elevated in both models of uveitis but may play a more significant role in PMU than EAU. The neuroprotective protein β-B2–crystallin was found to decline in EAU. Therapies to modulate these proteins in vivo may be good targets in the treatment of ocular inflammation. PMID:26747776

    To determine whether relationships exist between elevated laser flare photometry values and common abnormalities and complications associated with uveitis. We retrospectively studied all patients with uveitis on whom laser flare photometry measurements ("flare") were obtained (N = 111) at 2 academic medical centers. The first laser flare photometry values obtained for each patient were compared with the presence or absence of the following abnormalities or complications associated with uveitis: keratic precipitates, posterior synechiae, cataract, macular edema, optic disc edema, and glaucoma. In bilateral cases, the eye with the higher flare was used in primary analyses. Flare was significantly higher in patients with posterior synechiae (P<.001) and in those with macular edema (P =.02) than in patients with uveitis who did not have these complications. Flare was significantly higher in patients with prior cataract surgery or cataract at the study visit than in those without cataracts (P =.001). There was no significant difference in flare between patients with and without keratic precipitates, optic disc edema, or glaucoma. No relationships were found between abnormalities or complications and the level of inflammatory cells or flare as determined by clinical assessment. We also identified an inverse relationship between flare and visual acuity that was not completely explained by the presence of complications in a stepwise regression model. Although causal relationships were not established, associations between flare and some complications of uveitis suggest that aqueous humor protein may be an important factor in the development of these problems. Consequently, laser flare photometry could play a role in predicting outcomes or monitoring therapy for patients with uveitis.

    Forty-four patients with symptomatic chronic anterior cruciate ligament instabilities that had been reconstructed with the central one-third patellar tendon and a lateral extraarticular iliotibial band tenodesis were studied at an average followup of 7 years (range, 4 to 10). The cases with associated medial, lateral, or posterior laxity were not included, nor were the cases with more than minimal preoperative degenerative changes. The average age at surgery was 21 years (range, 16 to 33). A postoperative cast was used for 4 weeks. Satisfactory objective stability, which was defined as a KT-1000 side-to-side difference of up to 5 mm at the manual maximum test, was obtained in 37 (84%) of the patients. In 25 patients (57%), stability was restored within normal limits (less than or equal to 3 mm). No deterioration of the KT-1000 stability was noted at two follow-up visits performed by the same examiner (at an average of 4 and 7 years). A return to high-risk sports was possible in 27 (62%) of the patients. Difficulties in regaining a complete range of motion were recorded in 5 (11%) of the patients. A flexion contracture of 5 degrees to 7 degrees was also found in 5 patients. Significant patellofemoral symptoms were present in 4 patients (9%). A 5% to 11% shortening of the patella tendon was observed in 14 (32%) of the knees, but did not correlate with patellar problems. Moderate radiographic changes were noted in eight patients (18%) at followup and correlated with meniscectomy and pain. Overall satisfactory results were obtained in this initial experience in 29 (66%) of the patients.(ABSTRACT TRUNCATED AT 250 WORDS)

    Although the incidence of acute death related to coronary artery disease has decreased with the advent of new interventional therapies, myocardial infarction remains one of the leading causes of death in the US. Current animal models developed to replicate this phenomenon have been associated with unacceptably high morbidity and mortality. A new model utilizing the first diagonal branch of the left anterior descending artery (D1-LAD) was developed to provide a clinically relevant lesion, while attempting to minimize the incidence of adverse complications associated with infarct creation. Eight Yucatan miniature pigs underwent percutaneous embolization of the D1-LAD via injection of 90 µm polystyrene micro-spheres. Cardiac structure and function were monitored at baseline, immediately post-operatively, and at 8-weeks post-infarct using transthoracic echocardiography. Post-mortem histopathology and biochemical analyses were performed to evaluate for changes in myocardial structure and extracellular matrix (ECM) composition respectively. Echocardiographic data were evaluated using a repeated measures analysis of variance followed by Tukey's HSD post hoc test. Biochemical analyses of infarcted to non-infarcted myocardium were compared using analysis of variance. All eight pigs successfully underwent echocardiography prior to catheterization. Overall procedural survival rate was 83% (5/6) with one pig excluded due to failure of infarction and another due to deviation from protocol. Ejection fraction significantly decreased from 69.7 ± 7.8% prior to infarction to 50.6 ± 14.7% immediately post-infarction, and progressed to 48.7 ± 8.9% after 8-weeks (p = 0.011). Left ventricular diameter in systole significantly increased from 22.6 ± 3.8 mm pre-operatively to 30.9 ± 5.0 mm at 8 weeks (p = 0.016). Histopathology showed the presence of disorganized fibrosis on hematoxylin and eosin and Picro Sirius red stains. Collagen I and sulfated glycosaminoglycan content were

    Intraocular inflammation leads to oxidative stress and may generate lipid oxidation products. The present study was conducted to elucidate the pathophysiological roles of the lysosomal phospholipase A2 (LPLA2), a phospholipid-degrading enzyme, and the production of oxidized phospholipids (oxPLs) in autoimmune uveitis using a rat model. Lewis rats were immunized with a bovine interphotoreceptor retinoid-binding protein (bIRBP) peptide with complete Freund's adjuvant (CFA) to induce experimental autoimmune uveitis (EAU). The aqueous humor (AH) and serum were collected every week for 4 weeks from the immunized rats. The LPLA2 activity of the AH and serum was detected using liposomes consisting of 1,2-dioleoylphosphatidylglycerol/N-acetylsphingosine as the substrate under acidic conditions. Immunohistochemical analysis was performed using antibodies against LPLA2 and oxPLs. The ocular inflammation was exacerbated at 2 weeks after immunization. The LPLA2 activity in the rat AH was increased by EAU induction, and was concomitant with the extent of inflammation in the anterior chamber (AC). In contrast, the LPLA2 activity in the rat serum was not influenced by EAU induction. At 2 weeks after immunization, immunoreactivity of LPLA2 was observed in infiltrated macrophages in the AC and vitreous cavity of the EAU rats. Furthermore, immunoreactivity of oxPLs was observed in the infiltrated macrophages of EAU rat eyes. These results demonstrated that the LPLA2 activity of the AH is augmented with the inflammation in the AC. The high expression of LPLA2 and production of oxPLs are found in the infiltrated macrophages in the acute inflammation of EAU rats. The present findings suggest the connection between LPLA2 activity and oxPL metabolism in the inflammation sites in the eye. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The aim of the study was to investigate the characteristics of ocular toxocariasis (OT) presenting with intermediate uveitis in the Korean population.We studied intermediate uveitis patients using ocular and systemic evaluations and a Toxocara IgG serology test.Of 50 intermediate uveitis patients, 19 were seropositive for Toxocara IgG. Of the 19 OT patients, 4 presented with recurrence within 6 months and were significantly younger than nonrecurrence patients (P = 0.009). Thirteen patients had a history of eating raw cow liver.There were 14 males and 5 females in the OT group, and 11 males and 20 females in the non-OT group (P = 0.009). There was bilateral involvement in 7 out of 19 patients in the OT group, and 20 out of 31 patients in non-OT group (P = 0.033).Intermediate uveitis patients in OT were predominately male and had more unilateral presentation than non-OT patients.

    To identify and quantify the prevalence of patients with uveitis receiving systemic immunosuppression in Scotland. Anonymised data were prospectively collected on all patients with uveitis requiring systemic immunosuppression. Seven health boards participated over a 4-month period between 1 August 2005 and 30 November 2005. 373 patients were identified, of whom 205 (55%) were female. The mean age was 46.4 (range 7-97 years). Using the data from the seven participating health boards, an estimated Scottish prevalence of 9 per 100 000 was calculated. Prevalence varied between 2 and 59 per 100 000. In National Health Service Grampian, all patients with uveitis, whether sight-threatening or not, are followed up at a specialist clinic. Extrapolating this figure to Scotland gives a prevalence of 25 per 100 000. The data from National Health Service Grampian suggest that there is a significant shortfall in the number of patients identified by survey. If the "missing population" exists, then where are they? Some might be receiving appropriate treatment at non-specialist clinics, although simple under-reporting may play a part. Greater concern is for those patients receiving inappropriate treatment for their uveitis, or for those within the community who are either oblivious to or in self denial of their condition.

    Purpose Uveitis is the inflammation of the uveal tract, which usually also affects the retina and vitreous humor. The electrophysiological examination is an objective ocular examination that includes the electroretinogram, visual evoked potentials, the electrooculogram, the multifocal electroretinogram, and multifocal visual evoked potentials. Our aim is to review the literature of the use of the electrophysiological examination in cases of uveitis. Methods We performed a systematic search of the literature of published papers until October 2012 using the PubMed search engine. The key terms that were used were “uveitis”, “electrophysiological examination”, “electroretinogram”, “visual evoked potentials”, “electrooculogram”, “multifocal electroretinogram”, and “multifocal visual evoked potentials” in multiple combinations. To the best of our knowledge, this is the first review concerning the assessment of electrophysiology in uveitis. Results Our search of the literature demonstrated that the electrophysiological examination, mainly by means of electroretinogram, multifocal electroretinogram, and visual evoked potentials, is performed in several cases of uveitis for many purposes, including diagnosis and monitoring of disease progression and treatment efficacy. The electrophysiological examination is more useful in patients with multiple evanescent white dot syndrome, acute posterior multifocal placoid pigment epitheliopathy, birdshot chorioretinopathy, Vogt–Koyanagi–Harada disease, Adamantiades–Behçet disease, ocular syphilis, and Fuchs heterochromic cyclitis. Conclusion This review summarizes the use of the electrophysiological examination in uveitic patients and underlines its value as a useful tool in the objective assessment and the monitoring of the disease.

    Abstract The aim of the study was to investigate the characteristics of ocular toxocariasis (OT) presenting with intermediate uveitis in the Korean population. We studied intermediate uveitis patients using ocular and systemic evaluations and a Toxocara IgG serology test. Of 50 intermediate uveitis patients, 19 were seropositive for Toxocara IgG. Of the 19 OT patients, 4 presented with recurrence within 6 months and were significantly younger than nonrecurrence patients (P = 0.009). Thirteen patients had a history of eating raw cow liver. There were 14 males and 5 females in the OT group, and 11 males and 20 females in the non-OT group (P = 0.009). There was bilateral involvement in 7 out of 19 patients in the OT group, and 20 out of 31 patients in non-OT group (P = 0.033). Intermediate uveitis patients in OT were predominately male and had more unilateral presentation than non-OT patients. PMID:28151857

    Non-infectious uveitis—or intraocular inflammatory disease—causes substantial visual morbidity and reduced quality of life amongst affected individuals. To date, research of pathogenic mechanisms has largely been focused on processes involving T lymphocyte and/or myeloid leukocyte populations. Involvement of B lymphocytes has received relatively little attention. In contrast, B-cell pathobiology is a major field within general immunological research, and large clinical trials have showed that treatments targeting B cells are highly effective for multiple systemic inflammatory diseases. B cells, including the terminally differentiated plasma cell that produces antibody, are found in the human eye in different forms of non-infectious uveitis; in some cases, these cells outnumber other leukocyte subsets. Recent case reports and small case series suggest that B-cell blockade may be therapeutic for patients with non-infectious uveitis. As well as secretion of antibody, B cells may promote intraocular inflammation by presentation of antigen to T cells, production of multiple inflammatory cytokines and support of T-cell survival. B cells may also perform various immunomodulatory activities within the eye. This translational review summarizes the evidence for B-cell involvement in non-infectious uveitis, and considers the potential contributions of B cells to the development and control of the disease. Manipulations of B cells and/or their products are promising new approaches to the treatment of non-infectious uveitis. PMID:26962453

    The bacteria that live normally in our intestinal tract, or the gut microbiota contribute to the pathogenesis of extra intestinal autoimmune disease via their ability to dynamically educate the immune system. For example, in a mouse model of relapsing, remitting multiple sclerosis (MS), experimental autoimmune encephalomyelitis or EAE, several studies demonstrated that commensal microorganisms are essential in causing clinical disease activity. Interestingly, MS patients have a distinct gut microbiota to healthy controls. Several studies have also illustrated the importance of the gut microbiome in the development of other diseases, including Type 1 diabetes, metabolic syndrome, rheumatoid arthritis, and ankylosing spondylitis.more » Furthermore, HLA=B27 transgenic rats, which develop spontaneous spondyloarthropathy analogous to patients who have ankylosing spondylitis, associated with uveitis in humans, do not develop intestinal or peripheral join inflammation when raised in a germ-free environment. Our group has shown that HLA-B27 transgenic rats have an altered intestinal microbiota compared to healthy control rats. Given the similarities between the central nervous system (CNS) and the retina, as well as co-expression of potentially immunogenic self-antigens from the CNS and joint in the eye, we hypothesized that modulating the gut microbiome can result in amelioration of autoimmune uveitis. Although uveitis is a heterogeneous collection of diseases, in general immune-mediated, non-infectious, uveitis is thought to be due to a combination of genetic and environmental factors. It arises from an imbalance between the regulatory and effector arms of the immune system, result in an inappropriate immune reaction at an otherwise immune-privileged tissue site, the eye.

    Purpose. To investigate the effect of aldose reductase (AR) deficiency in protecting the chronic experimental autoimmune (EAU) and acute endotoxin-induced uveitis (EIU) in c57BL/6 mice. Methods. The WT and AR-null (ARKO) mice were immunized with human interphotoreceptor retinoid-binding peptide (hIRPB-1–20), to induce EAU, or were injected subcutaneously with lipopolysaccharide (LPS; 100 μg) to induce EIU. The mice were killed on day 21 for EAU and at 24 hours for EIU, when the disease was at its peak, and the eyes were immediately enucleated for histologic and biochemical studies. Spleen-derived T-lymphocytes were used to study the antigen-specific immune response in vitro and in vivo. Results. In WT-EAU mice, severe damage to the retinal wall, especially to the photoreceptor layer was observed, corresponding to a pathologic score of ∼2, which was significantly prevented in the ARKO or AR inhibitor–treated mice. The levels of cytokines and chemokines increased markedly in the whole-eye homogenates of WT-EAU mice, but not in ARKO-EAU mice. Further, expression of inflammatory marker proteins such as inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, tumor necrosis factor (TNF)-α, and vascular cell adhesion molecule (VCAM)-1 was increased in the WT-EIU mouse eyes but not in the ARKO-EIU eyes. The T cells proliferated vigorously when exposed to the hIRPB antigen in vitro and secreted various cytokines and chemokines, which were significantly inhibited in the T cells isolated from the ARKO mice. Conclusions. These findings suggest that AR-deficiency/inhibition protects against acute as well as chronic forms of ocular inflammatory complications such as uveitis. PMID:21911582

    To describe the outcomes of phacoemulsification with the implant of an acrylic intraocular lens (IOL) in cataracts of adult patients with and without uveitis Descriptive retrospective comparative study of 35 patients (45 eyes) with uveitis (group 1) and 38 (44 eyes) control patients (group 2), who were operated on by the same surgeon, and were homogeneous as regards sex, surgical technique, IOL (hydrophobic or hydrophilic) and follow-up. The pre-surgical characteristics of risk, the difficulties and intra-surgical and postsurgical complications, the date of posterior capsulotomy (PC) and the pre- and post-surgical visual acuity (VA), were analysed. In both groups the coaxial phacoemulsification was used in 75% of the eyes, bimanual microincision cataract surgery (MICS) in 20% and micro-coaxial in the rest. The pre-surgical risk factors (P = .002, OR 6.83), the surgical difficulties and complications (P = .001, OR 7.54) and postsurgical complications (P = .069, OR 3.42) were more frequent in the uveitis group. In both 93% and 91% respectively of eyes improved 2 or more lines of VA. After an average follow-up of 4.9 years in both groups, 22.7% and 32% eyes (log-rank P = .357) needed PC. The hydrophilic IOLs needed PC earlier than the hydrophobic ones (log rank P = .001), neither the location nor the uveitis course influenced the PC rate. The consequences because of previous ocular inflammation make cataract surgery in uveitis more difficult, but with postsurgical complications, visual results and need of PC similar to our patients without inflammation.

    Purpose This study evaluated the prevalence of ocular toxocariasis (OT) in patients with uveitis of unknown etiology who visited a tertiary hospital in South Korea and assessed the success of serum anti-Toxocara immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) as a diagnostic test for OT. Methods The records of consecutive patients with intraocular inflammation of unknown etiology were reviewed. All participants underwent clinical and laboratory investigations, including ELISA for serum anti-Toxocara IgG. OT was diagnosed based on typical clinical findings. Clinical characteristics, seropositivity, and IgG titers were compared between patients diagnosed with OT and non-OT uveitis. The seropositivity and the diagnostic value of anti-Toxocara IgG was investigated among patients with different types of uveitis. Results Of 238 patients with uveitis of unknown etiology, 71 (29.8%) were diagnosed with OT, and 80 (33.6%) had positive ELISA results for serum anti-Toxocara IgG. The sensitivity and specificity of the ELISA test were 91.5% (65 / 71) and 91.0% (152 / 167), respectively. The positive predictive value of the serum anti-Toxocara IgG assay was 81.3%. Among patients with anterior, intermediate, posterior, and panuveitis, the prevalence rates of OT were 8.3%, 47.1%, 44.8%, and 7.1%, respectively; the seropositivity percentages were 18.1%, 47.1%, 43.7%, and 17.9%; and the positive predictive values were 38.5%, 95.8%, 92.1%, and 40.0%. The serum anti-Toxocara IgG titer also significantly decreased following albendazole treatment. Conclusions OT is a common cause of intraocular inflammation in the tertiary hospital setting. Considering that OT is more prevalent in intermediate and posterior uveitis, and that the positive predictive value of the anti-Toxocara IgG assay is high, a routine test for anti-Toxocara IgG might be necessary for Korean patients with intermediate and posterior uveitis.

    Purpose To analyze the involvement of the corneal endothelium in uveitis to better understand the formation mechanisms and the keratic precipitate composition. In vivo confocal microscopy images were correlated with ex vivo immunostaining of corneal endothelium from rat eyes with endotoxin-induced uveitis (EIU). Methods EIU was induced in Lewis rats by lipopolysaccharide (LPS) injection. Slit-lamp examination and in vivo confocal microscopy were performed 6, 24, 48, 72, and 96 h after the LPS injection. One group of rats was killed at 24 h and the other rats at 96 h. Immunohistochemistry on corneal endothelium using antibodies to intercellular adhesion molecule (ICAM-1), phalloidin, CD68 (anti-macrophage), MCA967 (anti-granulocyte), T cell receptor alpha/beta (TCR alpha/beta; anti-lymphocyte), zonula occludens-1 (ZO-1), and occludin was performed on flat-mount corneas and was analyzed using a three dimensional (3D) laser confocal microscope. Results In vivo confocal microscopy showed numerous hyperreflective round dots on the corneal endothelium, in the anterior chamber, and in the anterior stroma corresponding to inflammatory cells with a maximum at 24 h after the injection and detectable until the 96th hour. Upon immunostaining, corneal endothelial cells in rats with EIU overexpressed ICAM-1. ZO-1 and occludin had a lower endothelial expression and more heterogeneous distribution in EIU rats than in controls, showing disruption of endothelial cell junctions. Compared to controls, CD68, MCA967, and TCR alpha/beta expression was observed in corneas in rats with EIU. The two techniques showed a circular peripheral network of corneal vessels derived from a large circumferential vascular structure resembling the major arterial circle of iris where the inflammatory cells marginalized to infiltrate the anterior stroma. Conclusions The correlation between in vivo confocal microscopy and ex vivo immunostaining helped to better understand in vivo confocal microscopy images

    Purpose To prospectively study the relationship between Fuchs heterochromic uveitis syndrome (FHUS) and intraocular production of specific antibodies against the rubella virus (RV) in Slovenia. Methods Using the Goldmann-Witmer coefficient technique, intraocular synthesis of specific antibodies against RV, herpes simplex virus, varicella-zoster virus, cytomegalovirus (CMV) and Toxoplasma gondii–specific immunoglobulin G antibodies was performed in 12 consecutive patients with clinically diagnosed FHUS and 12 patients with idiopathic recurrent unilateral anterior uveitis (AU) without clinical features of FHUS. Results Specific intraocular antibody synthesis against RV with a positive Goldmann-Witmer coefficient was proven in 11 of 12 (92%) FHUS patients, and in none of the non-FHUS AU patients (Fisher’s exact test <0.0001). In one patient with FHUS, specific antibodies against RV and varicella-zoster virus were concurrently detected. Specific antibodies against cytomegalovirus were detected in one patient with unilateral recurrent AU. Conclusions Intraocular production of specific immunoglobulin G against RV was proven in the majority of tested cohort of FHUS patients from Slovenia as compared to the group of patients with idiopathic AU, which suggests that RV is involved in the pathogenesis of FHUS in this geographic area.

    To determine the characteristics of immune recovery uveitis (IRU) in acquired immunodeficiency syndrome (AIDS) patients with inactive cytomegalovirus (CMV) retinitis who responded to highly active antiretroviral therapy (HAART) in a Venezuelan population. We examined 34 patients (50 eyes) with AIDS (HAART responders) and healed CMV retinitis. Patients were observed for a median of 19.3 months following an increase in the CD4 cell count. Ten eyes were treated with sub-Tenon space corticosteroid injections. An age-matched control group of patients with healed CMV retinitis who did not have IRU (30 eyes of 20 patients) was included to compare CMV surface area and complications. We found that 12 (37.5%) of 32 HAART responders developed IRU (18 eyes). The clinical findings of these 18 eyes with IRU are presented. The clinical spectrum of inflammation included vitritis, macular edema, epiretinal membranes, anterior uveitis, macular hole, retinal detachment with proliferative vitreoretinopathy, and cataract. Eyes with IRU had a mean CMV surface area of 31.7%. However, eyes without IRU (control group) had a mean CMV surface area of 35% (P = 0.41). Periocular treatment resulted in vision improvement (in 90% of eyes) without reactivation of retinitis. Symptomatic IRU developed in a significant number of patients with CMV retinitis following successful HAART in a Venezuelan population. CMV surface area does not seem to be a risk factor for the development of IRU. Eyes with IRU respond favorably to antiinflammatory therapy without reactivation of retinitis.

    Uveitis is a sight-threatening intraocular inflammatory disorder which may occur from both infectious and non-infectious or autoimmune causes. The frequency of infectious uveitis and autoimmune uveitis varies depending on countries and regions. According to a nationwide survey conducted by the Japanese Ocular Inflammation Society, infectious and non-infectious uveitis accounted for 16.4 and 50.1% of new patients, respectively while the remaining 33.5% of new uveitis cases were not classified or were idiopathic uveitis. Infectious uveitis is particularly important because it causes tissue damage to the eye and may result in blindness unless treated. However, it can be treated if the pathogenic microorganisms are identified promptly and accurately. Remarkable advancements in molecular and immunological technologies have been made in the last decade, and the diagnosis of infectious uveitis has been greatly improved by the application of molecular and immunological investigations, particularly polymerase chain reaction (PCR). PCR performed on a small amount of ocular samples provides a prompt, sensitive, and specific molecular diagnosis of pathogenic microorganisms in the eye. This technology has opened a new era in the diagnosis and treatment of uveitis, enabling physicians to establish new clinical entities of uveitis caused by infectious microorganisms, identify pathogens in the eyes of many patients with uveitis, and determine prompt diagnosis and appropriate therapy. Here we review the PCR process, new PCR tests specialized for ocular diseases, microorganisms detected by the PCR tests, diseases in the eye caused by these microorganisms, and the clinical characteristics, diagnosis, and therapy of uveitis.

    To characterize the risk and risk factors for intraocular pressure (IOP) elevation in pediatric noninfectious uveitis. Multicenter retrospective cohort study. Nine hundred sixteen children (1593 eyes) younger than 18 years at presentation with noninfectious uveitis followed up between January 1978 and December 2007 at 5 academic uveitis centers in the United States. Medical records review by trained, certified experts. Prevalence and incidence of IOP of 21 mmHg or more and 30 mmHg or more and incidence of a rise in IOP by 10 mmHg or more. To avoid underascertainment, outcomes were counted as present when IOP-lowering therapies were in use. Initially, 251 (15.8%) and 46 eyes (2.9%) had IOP ≥21 mmHg and ≥30 mmHg, respectively. Factors significantly associated with presenting IOP elevation included age of 6 to 12 years (versus other pediatric ages), prior cataract surgery, pars plana vitrectomy, duration of uveitis ≥6 months, contralateral IOP elevation, presenting visual acuity worse than 20/40, and topical corticosteroid use (in a dose-response relationship). The median follow-up was 1.25 years (interquartile range, 0.4-3.66). The estimated incidence of any observed IOP elevation to ≥21 mmHg, to ≥30 mmHg, and increase in IOP by ≥10 mmHg was 33.4%, 14.8%, and 24.4%, respectively, within 2 years. Factors associated with IOP elevation included pars plana vitrectomy, contralateral IOP elevation (adjusted hazard ratio [aHR], up to 9.54; P < 0.001), and the use of topical (aHR, up to 8.77 that followed a dose-response relationship; P < 0.001), periocular (aHR, up to 7.96; P < 0.001), and intraocular (aHR, up to 19.7; P < 0.001) corticosteroids. Intraocular pressure elevation affects a large minority of children with noninfectious uveitis. Statistically significant risk factors include IOP elevation or use of IOP-lowering treatment in the contralateral eye and local corticosteroid use that demonstrated a dose-and route of administration-dependent relationship

    Inflammatory conditions such as autoimmune uveitis often occur in women of childbearing age. During pregnancy, women may experience exacerbations of their disease in the first trimester. In the later stages of pregnancy, however, the uveitis tends to remain less active. The management of uveitis during pregnancy is a challenging task, forcing the physician to re-evaluate the patient's current therapy and offer alternative options that pose the least risk to the patient and fetus. This article will review treatments widely used for uveitis, including corticosteroid therapy, anti-metabolites, calcineurin inhibitors, and biologic therapy. It will evaluate the use of these medications in pregnancy and the postpartum state.

    The purpose of the study was to describe the findings seen on anterior segment spectral domain optical coherence tomography (SD-OCT) in patients with anterior scleritis and determine the feasibility of using SD-OCT to image and grade the degree of scleral inflammation and monitor response to treatment. All patients underwent slit lamp examination by a uveitis specialist, and the degree of scleral inflammation was recorded. Spectral domain OCT imaging was then performed of the conjunctiva and scleral tissue using a standardized acquisition protocol. The scans were graded and compared to clinical findings. Twenty-eight patients with anterior scleritis and ten patients without ocular disease were included in the study. Seventeen of the scleritis patients were followed longitudinally. Common findings on SD-OCT in patients with active scleritis included changes in hyporeflectivity within the sclera, nodules, and visible vessels within the sclera. There was significant variation in findings on SD-OCT within each clinical grade of active scleritis. These changes on SD-OCT improved with treatment and clinical improvement. SD-OCT imaging provided various objective measures that could be used in the future to grade inflammatory activity in patients with anterior scleritis. Longitudinal imaging of patients with active scleritis demonstrated that SD-OCT may have great utility in monitoring response to treatment.

    Ocular inflammatory disease is a leading cause of vision loss worldwide. Uveitis encompasses a wide spectrum of pathology, both with respect to its etiology and the anatomic location within the eye. Inflammation can be confined to the eye and may also be seen systemically. The cornerstone of management of ocular inflammatory disease historically has been corticosteroids, which are invaluable in the immediate control of inflammation; however, corticosteroids are inappropriate for long-term use as they are associated with a wide array of toxic side effects. As we continue to learn more about the various etiologies and elucidate the basic science pathways and mechanisms of action that cause intraocular inflammation, new therapeutic approaches have evolved. They include employment of immunomodulatory agents (corticosteroid-sparing therapies) that have expanded our treatment options for these vision-threatening diseases. These pharmacologics provide therapy for ocular and systemic inflammation in an individualized, patient-tailored, stepladder approach with the ultimate goal of durable, corticosteroid-free remission. We review the preferred practice patterns of a tertiary care center specializing in ocular inflammatory disease.

    The purpose of the study was to report a case of multiple sclerosis (MS)-associated uveitis refractory to conventional immunosuppressants, with subsequent remission following treatment with alemtuzumab. Case report Patient was treated with intravenous alemtuzumab, a lymphocyte depleting anti-CD52 monoclonal antibody that has recently been approved for use in relapsing MS. A 17-year-old female presented with bilateral optic neuritis and subsequently bilateral intermediate uveitis and secondary macular oedema. She was diagnosed with active relapsing MS for which she received treatment with alemtuzumab. The intraocular inflammation previously refractory to conventional immunosuppressants responded to alemtuzumab, inducing remission. To our knowledge, this is the first such report of alemtuzumab treatment in MS-associated ocular inflammatory disease and may demonstrate a potential utility for this drug in related conditions.

    Uveitides can be due to non-infectious and infectious etiologies. It has been observed that there is a gender difference with a greater preponderance of non-infectious uveitis in women than in men. This review will describe both non-infectious and infectious uveitides and describes some of the current autoimmune mechanisms thought to be underlying the gender difference. It will specifically look at non-infectious uveitides with systemic involvement including juvenile idiopathic arthritis, spondyloarthopathies, sarcoidosis, Behçet’s disease, and Vogt-Koyanagi-Harada disease and at uveitides without systemic involvement including sympathetic ophthalmia, birdshot chorioretinitis, and the white dot syndromes. Infectious uveitides like acute retinal necrosis, progressive outer retinal necrosis, and cytomegalovirus mediated uveitis will be mentioned. Different uveitides with female- or male- predominance are presented and discussed. PMID:26035764

    Introduction: Progressive hemifacial atrophy, known as Parry-Romberg syndrome (PRS), was first described by Parry in 1825. There is a progressive atrophy of facial tissues including skin, bones and muscles. Ophthalmic disorders are common and include keratitis, uveitis, cataract, ipsilateral enophthalmos, optic neuritis, retinal vasculitis and scleral melting. Case Presentation: We describe a patient with progressive hemifacial atrophy at right facial side who developed granulomatous uveitis and periferic retinal vasculitis in his left eye. We started topical and systemic steroid therapy. Uveitic reaction had regressed almost entirely after a 3-month steroid treatment. Conclusions: The individuals should have multidisciplinary approach for the variety of disorders to maintain the appropriate treatment for a better appearance of the patients. PMID:26473067

    To evaluate the outcome of orbital floor injection of betamethasone and methylprednisolone in the management of uveitis, with particular reference to its efficacy in avoiding increase in systemic immunosuppressive drugs. A sample of all patients attending the Uveitis Service at Moorfields Eye Hospital was carried out over a three-month period. All patients who had received one or more orbital floor injections of betamethasone (4 mg) and methylprednisolone (Depo-Medrone; 40 mg) in the management of their uveitis were identified and the case notes reviewed. A total of 48 patients who had received 75 orbital floor injections were identified during the sample period. Most patients had either panuveitis (n = 24) or pars planitis (n = 14). One-month post-injection visual acuity (VA) had improved by at least one Snellen line after 33/75 injections (44%) and at least two lines after 11/75 (15%), was unchanged after 25 (33%), but had deteriorated in 14 (19%). VA was not recorded after 3/75 injections. The only complications recorded were periorbital haemorrhage (n = 1) and complaints of persistent pain after an injection (n = 1). Symptoms (pain and subjective vision) improved after 36/75 injections (47%), were unchanged after 24 (32%), and were reported as worse after five (7%). Additionally, three patients reported an improvement in symptoms which lasted less than one month. Signs other than VA were improved after 28/75 (37%), were unchanged after 38 (51%), and deteriorated after only one injection. Of the 31 patients given orbital floor injections to avoid systemic therapy, seven (23%) subsequently went on to require it, and the clinical course then improved in 45%. Combined orbital floor injection of betamethasone and methylprednisolone can result in improved visual acuity, symptoms, and signs of inflammation in uveitis, and may therefore avoid the necessity for increased systemic medication.

    Interleukin-33 (IL-33) is associated with several important immune-mediated disorders. However, its role in uveitis, an important eye inflammatory disease, is unknown. Here, we investigated the function of IL-33 in the development of experimental autoimmune uveitis (EAU). IL-33 and IL-33 receptor (ST2) were expressed in murine retinal pigment epithelial (RPE) cells in culture, and IL-33 increased the expression of Il33 and Mcp1 mRNA in RPE cells. In situ, IL-33 was highly expressed in the inner nuclear cells of the retina of naïve mice, and its expression was elevated in EAU mice. ST2-deficient mice developed exacerbated EAU compared with WT mice, and administration of IL-33 to WT mice significantly reduced EAU severity. The attenuated EAU in IL-33-treated mice was accompanied by decreased frequency of IFN-γ+ and IL-17+ CD4+ T cells and reduced IFN-γ and IL-17 production but with increased frequency of IL-5+ and IL-4+ CD4 T cells and IL-5 production in the draining lymph node and spleen. Macrophages from the IL-33-treated mice show a significantly higher polarization toward an alternatively activated macrophage phenotype. Our results therefore demonstrate that the endogenous IL-33/ST2 pathway plays an important role in EAU, and suggest that IL-33 represents a potential option for treatment of uveitis. PMID:25116404

    Equine recurrent uveitis serves as a spontaneous model for human autoimmune uveitis. Unpredictable relapses and ongoing inflammation in the eyes of diseased horses as well as in humans lead to destruction of the retina and finally result in blindness. However, the molecular mechanisms leading to inflammation and retinal degeneration are not well understood. An initial screening for differentially regulated proteins in sera of uveitic cases compared to healthy controls revealed an increase of the alternative pathway complement component factor B in ERU cases. To determine the activation status of the complement system, sera were subsequently examined for complement split products. We could demonstrate a significant higher concentration of the activation products B/Ba, B/Bb, Bb neoantigen, iC3b and C3d in uveitic condition compared to healthy controls, whereas for C5b-9 no differences were detected. Additionally, we investigated complement activation directly in the retina by immunohistochemistry, since it is the main target organ of this autoimmune disease. Interestingly, infiltrating cells co-expressed activated factor Bb neoantigen, complement split product C3d as well as CD68, a macrophage marker. In this study, we could demonstrate activation of the complement system both systemically as well as in the eye, the target organ of spontaneous recurrent uveitis. Based on these novel findings, we postulate a novel role for macrophages in connection with complement synthesis at the site of inflammation.

    Cyclosporin A (CS-A), a selective inhibitor of T lymphocytes, is reported here to prevent S antigen (S-Ag) induced uveitis in Lewis rats. The S-Ag, found in all mammalian retinas, is uveitogenic under experimental conditions and patients with certain uveitic entities demonstrate cell mediated responses to this antigen. Daily treatment with CS-A (10 mg/kg) begun on the same day as S-Ag immunization totally inhibited the development of the uveitis in this experimental autoimmune model. Moreover a greater CS-A dose (40 mg/kg) efficiently prevented the disease process when therapy was started 7 d after S-Ag immunization. Anti-S-Ag antibody titers were observed to be similar in rats either protected or not protected with CS-A. Our data support strongly the need for T cell participation in this disease model. Since ocular inflammatory disease is an important cause of visual impairment, the data further suggest that CS-A may be useful in the treatment of patients with intractable uveitis.

    The aim of this study is to assess uveitis prevalence in a large cohort of childhood-onset systemic lupus erythematosus (cSLE) patients. A retrospective multicenter cohort study including 852 cSLE patients was performed in ten pediatric rheumatology centers (Brazilian cSLE group). An investigator meeting was held and all participants received database training. Uveitis was diagnosed through clinical assessment by the uveitis expert ophthalmologist of each center. Patients with and without uveitis were assessed for lupus clinical/laboratory features and treatments. Uveitis was observed in 7/852 cSLE patients (0.8%). Two of them had ocular complications: cataract and irreversible blindness in one patient and retinal ischemia with subsequent neovascularization and unilateral blindness in another. Uveitis was identified within the first 6 months of cSLE diagnosis in 6/7 patients (86%). Comparison of a subgroup of cSLE patients with (n = 7) and without uveitis (n = 73) and similar length of disease duration showed that patients with uveitis had increased SLEDAI-2K score (19 vs. 6; p < 0.01). In addition, fever (71 vs. 12%; p < 0.01), lymphadenopathy (29 vs. 1.4%; p = 0.02), arthritis (43 vs. 7%; p = 0.02), and use of intravenous methylprednisolone (71 vs. 22%; p = 0.01) were higher in cSLE patients with uveitis, as compared to those without this manifestation, respectively. Presence of fever was significantly associated with uveitis, independently of SLEDAI scores or use of intravenous methylprednisolone pulses, as shown by adjusted regression analysis (adjusted prevalence ratio 35.7, 95% CI 2.4-519.6; p < 0.01). Uveitis was a rare and initial manifestation of active cSLE patients. Early recognition is essential due to the possibility of irreversible blindness.

    The aim of the present study was to evaluate the anti-inflammatory efficacy of Daclizumab, an anti-interleukin-2 receptor drug, in an experimental uveitis model upon a subcutaneous injection of lipopolysaccharide into Lewis rats, a valuable model for ocular acute inflammatory processes. The integrity of the blood-aqueous barrier was assessed 24 h after endotoxin-induced uveitis by evaluating two parameters: cell count and protein concentration in aqueous humors. The histopathology of all the ocular structures (cornea, lens, sclera, choroid, retina, uvea, and anterior and posterior chambers) was also considered. Enzyme-linked immunosorbent assays of the aqueous humor samples were performed to quantify the levels of the different chemokine and cytokine proteins. Similarly, a biochemical analysis of oxidative stress-related markers was also assessed. The inflammation observed in the anterior chamber of the eyes when Daclizumab was administered with endotoxin was largely prevented since the aqueous humor protein concentration substantially lowered concomitantly with a significant reduction in the uveal and vitreous histopathological grading. Th1 lymphocytes-related cytokines, such as Interleukin-2 and Interferon-γ, also significantly reduced with related anti-oxidant systems recovery. Daclizumab treatment in endotoxin-induced uveitis reduced Th1 lymphocytes-related cytokines, such as Interleukin-2 and Interferon gamma, by about 60–70% and presented a preventive role in endotoxin-induced oxidative stress. This antioxidant protective effect of Daclizumab may be related to several of the observed Daclizumab effects in our study, including IL-6 cytokine regulatory properties and a substantial concomitant drop in INFγ. Concurrently, Daclizumab treatment triggered a significant reduction in both the uveal histopathological grading and protein concentration in aqueous humors, but not in cellular infiltration.

    Equine recurrent uveitis (ERU) has various etiologies, with Leptospira infection and genetic predisposition being the leading risk factors. Regardless of etiology, expression of ocular proteins associated with maintenance of the blood-ocular barrier is impaired in ERU. The recurring-remitting cycle of ERU repeatedly disrupts the blood-ocular barrier, allowing the previously immune-privileged ocular environment to become the site of a progressive local autoimmune pathology that ultimately results in tissue destruction and vision loss. The immune-mediated process involves humoral and cellular mechanisms. Intraocular antibodies either produced in the eye or that leak through the blood-ocular barrier, are often present at higher levels than in serum and react with antigens in ocular tissue of horses with ERU. Ocular infiltration of auto-aggressive lymphocytes occurs with each uveitis episode and is the most crucial contributor to inflammation and eye damage. Recurring uveitis episodes may be initiated when epitopes of an ocular antigen become visible to the immune system (intramolecular spreading) or another autoantigen (intermolecular spreading), resulting in a new inflammatory reaction.

    Abstract Purpose: To determine the impact of anterior segment geometry on ocular scoring systems quantifying anterior chamber (AC) cells in humans and 7 common laboratory species. Methods: Using normative anterior segment dimensions and novel geometric formulae, ocular section volumes measured by 3 scoring systems; Standardization of Uveitis Nomenclature (SUN), Ocular Services On Demand (OSOD), and OSOD–modified SUN were calculated for each species, respectively. Calculated volumes were applied to each system's AC cell scoring scheme to determine comparative cell density (cells/mm3). Cell density values for all laboratory species were normalized to human values and conversion factors derived to create modified scoring schemes, facilitating interspecies comparison with each system, respectively. Results: Differences in anterior segment geometry resulted in marked differences in optical section volume measured. Volumes were smaller in rodents than dogs and cats, but represented a comparatively larger percentage of AC volume. AC cell density (cells/mm3) varied between species. Using the SUN and OSOD–modified SUN systems, values in the pig, dog, and cat underestimated human values; values in rodents overestimated human values. Modified normalized scoring systems presented here account for species-related anterior segment geometry and facilitate both intra- and interspecies analysis, as well as translational comparison. Conclusions: Employment of modified AC cell scoring systems that account for species-specific differences in anterior segment anatomy would harmonize findings across species and may be more predictive for determining ocular toxicological consequences in ocular drug and device development programs.

    Objective To assess whether cigarette smoking is associated with the development of uveitis in a population-based setting. Design Retrospective, population-based case-control study. Participants Patients ≥18 years of age seen at a Kaiser Permanente Hawaii clinic between January 1, 2006 and December 31, 2007. Analysis included 100 confirmed incident uveitis cases, 522 randomly selected controls from the general Kaiser Hawaii population, and 528 randomly selected controls from the Kaiser Hawaii ophthalmology clinic. Methods International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes were used to identify possible uveitis cases. A uveitis fellowship-trained ophthalmologist then conducted individual chart review to confirm case status. Multivariate logistic regression models were used to evaluate the association between smoking and uveitis, adjusting for age, sex, race, and socioeconomic status. Main Outcome Measure Development of uveitis. Results Current smokers had a 1.63 (95% CI 0.88 – 3.00, P=0.12) and 2.33 (95% CI 1.22 – 4.45, P=0.01) times greater odds of developing uveitis compared to never smokers using the general and ophthalmology control groups, respectively. The association was even stronger with non-infectious uveitis, which yielded ORs of 2.10 (95% CI 1.10 – 3.99 P=0.02) and 2.96 (95% CI 1.52 – 5.77, P=0.001) using the general and ophthalmology control groups, respectively. Conclusions Cigarette smoking is significantly associated with new onset uveitis within a population-based setting. The association was stronger for non-infectious uveitis. Given the well-established risks of smoking with regard to other inflammatory disorders, these results reaffirm the importance of encouraging patients to avoid or cease smoking. PMID:25835263

    The aim of this study was to assess the efficacy of anti-TNF-α therapy in refractory uveitis due to Behçet's disease (BD). We performed a multicentre study of 124 patients with BD uveitis refractory to conventional treatment including high-dose corticosteroids and at least one standard immunosuppressive agent. Patients were treated for at least 12 months with infliximab (IFX) (3-5 mg/kg at 0, 2 and 6 weeks and then every 4-8 weeks) or adalimumab (ADA) (usually 40 mg every 2 weeks). The main outcome measures were degree of anterior and posterior chamber inflammation, visual acuity, macular thickness and immunosuppression load. Sixty-eight men and 56 women (221 affected eyes) were studied. The mean age was 38.6 years (s.d. 10.4). HLA-B51 was positive in 66.1% of patients and uveitis was bilateral in 78.2%. IFX was the first biologic agent in 77 cases (62%) and ADA was first in 47 (38%). In most cases anti-TNF-α drugs were used in combination with conventional immunosuppressive drugs. At the onset of anti-TNF-α therapy, anterior chamber and vitreous inflammation was observed in 57% and 64.4% of patients, respectively. In both conditions the damage decreased significantly after 1 year. At baseline, 50 patients (80 eyes) had macular thickening [optical coherence tomography (OCT) >250 μm] and 35 (49 eyes) had cystoid macular oedema (OCT>300 μm) that improved from 420 μm (s.d. 119.5) at baseline to 271 μm (s.d. 45.6) at month 12 (P < 0.01). The best-corrected visual acuity and the suppression load also showed significant improvement. After 1 year of follow-up, 67.7% of patients were inactive. Biologic therapy was well tolerated in most cases. Anti-TNF-α therapy is effective and relatively safe in refractory BD uveitis. © The Author 2014.

    Purpose. To investigate the therapeutic effects of metformin, a commonly used antidiabetic drug, in preventing endotoxin-induced uveitis (EIU) in rats. Methods. EIU in Lewis rats was developed by subcutaneous injection of lipopolysaccharide (LPS; 150 μg). Metformin (300 mg/kg body weight, intraperitoneally) or its carrier was injected either 12 hours before or 2 hours after LPS induction. Three and 24 hours after EIU, eyes were enucleated and aqueous humor (AqH) was collected. The MILLIPLEX-MAG Rat cytokine-chemokine magnetic bead array was used to determine inflammatory cytokines. The expression of Cox-2, phosphorylation of AMPK, and NF-κB (p65) were determined immunohistochemically. Primary human nonpigmented ciliary epithelial cells (HNPECs) were used to determine the in vitro efficacy of metformin. Results. Compared with controls, the EIU rat AqH had significantly increased number of infiltrating cells and increased levels of various cytokines and chemokines (TNF-α, MCP-1, IL-1β, MIP-1α, IL-6, Leptin, and IL-18) and metformin significantly prevented the increase. Metformin also prevented the expression of Cox-2 and phosphorylation of p65, and increased the activation of AMPK in the ciliary bodies and retinal tissues. Moreover, metformin prevented the expression of Cox-2, iNOS, and activation of NF-kB in the HNPECs and decreased the levels of NO and PGE2 in cell culture media. Conclusions. Our results for the first time demonstrate a novel role of the antidiabetic drug, metformin, in suppressing uveitis in rats and suggest that this drug could be developed to prevent uveitis complications.

    Background Retinoblastomas account for 4% of malignancies in children, 1-2% of which are diffuse infiltrating retinoblastomas. Diffuse anterior retinoblastoma is rare and does not involve the retina. Here, we report on a diffuse anterior retinoblastoma with large sarcoidosis-like nodules on the iris that were responsive to anti-inflammatory therapy. Case We present a 6-year-old girl who had anterior uveitis with white nodules on the iris and posterior surface of the cornea in her right eye. The nodules initially responded well to anti-inflammatory treatment. However, anterior segment optical coherence tomography (AS-OCT) showed that the nodules gradually grew, shrinking the iris. We then collected the aqueous humor for diagnosis. A biopsy revealed clusters of small cells with a high nuclear-to-cytoplasm ratio with partial rosette formation. Therefore, we diagnosed diffuse anterior retinoblastoma without retinal involvement and performed enucleation of the right eye. The histopathology demonstrated undifferentiated cells similar to those seen on the biopsy, and tumor cells invaded the iris stroma, posterior surface of the cornea, ciliary body, and sclera. After the enucleation, she underwent chemotherapy and remains alive. Conclusion A differential diagnosis of retinoblastoma should be considered when white nodules refractory to anti-inflammatory therapy occur in the eye, even in the absence of obvious retinal masses. AS-OCT findings are useful in assessing retinoblastoma. PMID:26955346

    Anterior hip pain is a common complaint with many possible causes. Apophyseal avulsion and slipped capital femoral epiphysis should not be overlooked in adolescents. Muscle and tendon strains are common in adults. Subsequent to accurate diagnosis, strains should improve with rest and directed conservative treatment. Osteoarthritis, which is diagnosed radiographically, generally occurs in middle-aged and older adults. Arthritis in younger adults should prompt consideration of an inflammatory cause. A possible femoral neck stress fracture should be evaluated urgently to prevent the potentially significant complications associated with displacement. Patients with osteitis pubis should be educated about the natural history of the condition and should undergo physical therapy to correct abnormal pelvic mechanics. "Sports hernias," nerve entrapments and labral pathologic conditions should be considered in athletic adults with characteristic presentations and chronic symptoms. Surgical intervention may allow resumption of pain-free athletic activity.

    Purpose Existing flare photometers are based on the Tyndall effect, which requires sophisticated laser photometry. The ocular flare analysis meter (OFAM) is a nonlaser photometer that uses quantitative Rayleigh scatter and absorption from visible light to compute a flare value. This study is designed to correlate OFAM measurements with qualitative measurements of flare in vitro and in vivo. Methods Following validation of the device on artificial anterior chambers containing known protein concentrations, flare readings were obtained from 90 subjects (46 with and 44 without uveitis) in one eye. Subjects were graded by the Standardization of Uveitis Nomenclature (SUN) working group flare scoring system and received the OFAM flare measurements. Results The OFAM showed linear response in vitro to protein concentrations ranging from 0 to 0.5 mg/ml. In clinical use in subjects ranging from SUN flare scores of 0+ to 2+, OFAM showed statistically significant measurement accuracy (P = 0.0008 of flare 0 versus flare 2; P = 0.031 of flare 0 versus flare 1). Distinction of SUN scores 1 and 2 was borderline significant (P = 0.057). Conclusion The OFAM photometry correlates with the standard SUN scoring system. This method may provide an objective method to diagnosis and monitor uveitis. Further longitudinal studies are warranted. Translational Relevance Currently, ocular flare is assessed qualitatively in most clinical settings. The existing methodology uses only Tyndall effect to measure flare. The OFAM uses an alternate, nonlaser means for measurement of anterior chamber flare by measure of Raleigh scatter. This pilot clinical study suggests that the OFAM device may be useful in measurement of uveitis activity. PMID:26688778

    This retrospective study of 432 patients was conducted between 2000 and 2009 to compare immunosuppressive therapy responses in uveitis accompanied or unaccompanied by rheumatic diseases. We divided patients into two groups: uveitis related or unrelated to rheumatic diseases. The clinical improvement after treatment was measured at the end of the observation period. Of the 432 patients with uveitis, 33 (7.6%) patients suffered from associated rheumatic diseases and 399 (92.4%) patients did not. The groups showed similar clinical features, but the mean age at onset of uveitis was lower in the rheumatic disease group (44.06 ± 2.13 years vs. 48.23 ± 0.81 years). The rheumatic diseases included spondyloarthropathy (31%), Behcet's disease (27%), rheumatoid arthritis (18%), systemic lupus erythematosus (15%), Sjogren's syndrome (6%), and mixed connective tissue disease (3%). Erythrocyte sedimentation rate and C-reactive protein level were increased in uveitis associated with rheumatic diseases, whereas ocular complications were not. The response to immunosuppressive therapy was significantly increased in cases of uveitis associated with rheumatic diseases (P < 0.05). Therefore, during early treatment, uveitis accompanied by rheumatic diseases showed better response to immunosuppressive therapy and less frequent complications.

    Equine recurrent uveitis (ERU) is an inflammatory eye disease with high similarity to uveitis in man. It is the only spontaneous animal model for uveitis and the most frequent eye disease in horses affecting up to 10% of the population. To further investigate the pathophysiology of ERU we now report the establishment of an inducible uveitis model in horses. An ERU-like disease was elicited in seven out of seven horses by injection of interphotoreceptor retinoid-binding protein (IRBP) in complete Freund's adjuvant. Control horses did not develop uveitis. The disease model is characterized by a highly reproducible disease course and recurrent episodes with an identical time course elicited in all horses by repeated IRBP injections. The histology revealed the formation of lymphoid follicle-like structures in the eyes and an intraocular infiltration dominated by CD3(+) lymphocytes, morphological patterns typical for the spontaneous disease. Antigen-specific T cell proliferation of PBL was monitored prior to clinical uveitis and during disease episodes. An initial T cell response to IRBP-derived peptides was followed by epitope spreading to S-antigen-derived peptides in response to subsequent immunizations. Thus, horse experimental uveitis represents a valuable disease model for comparative studies with the spontaneous disease and the investigation of immunomodulatory therapeutic approaches after onset of the disease.

    Aim To evaluate whether aqueous humor levels of pigment epithelium‐derived factor (PEDF) are increased in patients with uveitis Methods Aqueous humor levels of PEDF and tumour necrosis factor α (TNFα) were determined by ELISA in 34 uveitis samples and 9 cataract control samples. Results Aqueous humor PEDF and TNFα levels were significantly higher in patients with uveitis than in controls (mean (SD) 6.4 (0.8) v 1.3 (0.2) μg/ml and 14.7 (3.8) v 4.2 (0.4) pg/ml, respectively; p<0.01). A positive correlation between PEDF and TNFα was found in patients with uveitis (r = 0.40, p<0.01). Furthermore, PEDF levels in aqueous humor were increased in proportion to the disease activity of uveitis. Conclusion The results show that aqueous humor levels of PEDF are increased in patients with uveitis. Our observations suggest that aqueous humor levels of PEDF may be increased as a countersystem against inflammation in uveitis. PMID:16973658

    Non-infectious uveitis is one of the leading causes of preventable blindness worldwide. Long-term immunosuppressive treatment is generally required to achieve durable control of inflammation in posterior and panuveitis. Although systemic corticosteroids have been the gold standard of immunosup- pressive treatment for uveitis since first introduced in 1950s, its side effects of long-term use often warrant an adjuvant treatment to reduce the dosage/duration of corticosteroids needed to maintain disease control. Conventional immunosuppressive drugs, classified into alkylating agent, antimetabolites and T cell inhibitors, have been widely used as corticosteroid-sparing agents, each with characteristic safety/tolerance profiles on different uveitis entities. Recently, biologic agents, which target specific molecules in immunopathogenesis of uveitis, have gained great interest as alternative treatments for refractory uveitis based on their favorable safety and effectiveness in a variety of uveitis entities. However, lack of large randomized controlled clinical trials, concerns about efficacy and safety of long-term usage, and economic burden are limiting the use of biologics in non-infectious uveitis. Local administration of immunosuppressive drugs (from corticosteroids to biologics) through intraocular drug delivery systems represent another direction for drug development and is now under intense investigation, but more evidences are needed to support their use as regular alternative treatments for uveitis. With the numerous choices belonging to different treatment modalities (conventional immunosuppressive agents, biologics and local drug delivery systems) on hand, the practice patterns have been reported to vary greatly from center to center. Factors influence uveitis specialists' choices of immunosuppressive agents may be complex and may include personal familiarity, treatment availability, safety/tolerability, effectiveness, patient compliance, cost concerns and

    In a prospective study we examined 32 athletes with arthroscopic implantation of a double loop of semitendinosus tendon for intra-articular anterior cruciate ligament reconstruction combined with an iliotibial band tenodesis for extra-articular augmentation. They were compared to 26 athletes operated by isolated intra-articular semitendinosus reconstruction. The Lysholm-Score, clinical and radiological findings, KT-1000 stability values and isokinetic tests were evaluated monthly over a year. The data suggests that while both procedures under standardized rehabilitation conditions may obtain excellent functional results, adding the iliotibial band tenodesis to an intra-articular reconstruction significantly improves stability and muscular strength. Patients were able to resume all activities without a pivot shift following combined intra- and extra-articular stabilization.

    The anterior cingulate cortex (ACC) is crucially involved in executive control of attention. Here, seven medication-naïve adult patients suffering from attention deficit/hyperactivity disorder (ADHD) were studied with 2D (1)H-magnetic resonance spectroscopic imaging (MRSI) of the ACC [Brodmann areas 24b'-c' and 32'] twice, once before initiation of stimulant treatment and once after 5-6 weeks of methylphenidate. Upon retest, all patients demonstrated marked clinical improvement. Analysis of regional brain spectra revealed a significantly decreased signal of choline containing compounds as well as increased N-acetyl-aspartate (NAA) levels following treatment with methylphenidate whereas total creatine remained unchanged. Our results add to a growing body of evidence implicating the ACC in the pathophysiology of ADHD and suggest that subtle structural changes might be associated with aspects of clinical improvement under stimulant treatment.

    Importance Fluoroquinolones (FQ) are the most commonly prescribed antibiotic in the outpatient setting. Recent reports have implicated an association between oral fluoroquinolones and an increased risk of uveitis. Objective To determine the hazard of uveitis with oral fluoroquinolone use. Design This is a retrospective cohort study using medical claims data from a large, national U.S. insurer. Cohorts were created using every new user of an oral fluoroquinolone or beta-lactam (BL) antibiotic prescription from 2000–2012. Setting Ambulatory care centers across the United States. Participants Any new user of an oral fluoroquinolone or beta-lactam antibiotic with at least 24 months of data prior to the date of the prescription was eligible. Exclusion criteria consisted of any previous diagnosis of uveitis or a uveitis-associated systemic illness. Subjects were censored for a new diagnosis of a uveitis-associated systemic illness, the end of an observation period, use of the other class of antibiotic, or removal from the plan. Main Outcome Measure The main outcome was the hazard of being diagnosed with uveitis after FQ prescription compared to a BL prescription using multivariate Cox regression. Results 843,854 FQ patients and 3,543,797 BL patients were included in analysis. Univariate analysis showed an increased hazard of uveitis for FQ users at every time point (HR range: 1.34–1.64; p<0.001 for all comparisons). After controlling for age, race, and gender using multivariate analysis, no hazard for developing uveitis at the 30-, 60-, or 90-day observation windows was seen (HRs 0.96–1.05; p>0.38 for all comparisons). The 365-day observation showed a small increase in hazard for the FQ cohort (HR=1.11; 95% CI: 1.05–1.17; p<0.001). Moxifloxacin showed an increased hazard for uveitis at every time point (HR range: 1.47–1.75; p<0.001 for all comparisons). Secondary analysis demonstrated a similar hazard at 365 days for a later diagnosis of a uveitis

    A female patient diagnosed with ankylosing spondylitis experienced a new onset acute iritis following the initiation of etanercept therapy and recurrent episodes of iritis continues during the treatment of etanercept. Etanercept-associated iritis was suspected. Anti-TNF therapies can alleviate uveitis in some studies, but in some other anecdotal reports etanercept is considered as the main cause of uveitis. A literature review is presented below. For clinicians, more attention must be paid to the potential association between uveitis or iritis and etanercept, and more careful surveillance of patients under etanercept treatment is necessary.

    Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a multisystem disease that can involve the human eyes. Using ophthalmic examination records from January 2006 to November 2015, we retrospectively reviewed all patients who were diagnosed with HIV/AIDS in our hospital. The study was performed at a tertiary referral center in southern Taiwan. Data included age, gender, ophthalmic examinations, systemic conditions, CD4 cell counts, course, and treatment. Eleven patients were identified as having AIDS with uveitis as their presenting manifestation. All were men, with a mean age of 39.5 ± 11.4 years (range 24-56). The mean CD4(+) T-cell counts were 91.7 ± 50.3 cells/μl (range 27-169). Ocular diagnoses included cytomegalovirus (CMV) retinitis in five patients, ocular syphilis in four patients, and ocular toxoplasmosis in two patients. Uveitis resolved in all patients after medical treatment. However, a retinal detachment developed in two eyes in CMV retinitis and one eye in ocular syphilis. Ocular manifestations are among the most common clinical features in patients with HIV/AIDS who have varying clinical presentations that affect almost all ocular structures. This study demonstrated that ocular findings could be an initial manifestation of an underlying disease. Awareness of ocular lesions in HIV/AIDS is important for early recognition and management.

    For evaluation of the effects of different free-radical scavengers on biochemical changes in lens-induced uveitis (LIU), ten male Wistar rats were sensitized for 8 weeks using bovine lens protein and Freund's adjuvant. The uveitis was induced by disruption of the lens capsule. One group of animals received superoxide dismutase and catalase (SOD/CAT); a second group of animals was treated with vitamin E. Lipid peroxides (LPO) of the retinal tissue and aqueous humor served as parameter of oxidative tissue damage. Glutathione (GSH/GSSG) of the aqueous humor was evaluated as a parameter of the tissue's redox state. For evaluation of the inflammatory response, myeloperoxidase activity (MPO) was determined in the iris/ciliary-body complex. SOD/CAT produced no improvement in the significantly (P < 0.05) elevated MPO and LPO values recorded for untreated control animals. Following vitamin E treatment the GSH/GSSG and LPO values in aqueous humor were markedly improved as compared with controls. Retinal LPO values were significantly (P < 0.05) reduced as compared with controls. No change in MPO levels was observed. The results demonstrate that enzymes such as SOD and CAT do not influence tissue damage at a significant level, whereas radical chain breakers such as vitamin E can do so. However, the inflammatory response itself is not reduced. To achieve global results, drugs are necessary that act on both free radicals produced by noninflammatory pathways and those originating from inflammation.

    A single amino acid mutation near the active site of the CAPN5 protease was linked to the inherited blinding disorder, autosomal dominant neovascular inflammatory vitreoretinopathy (ADNIV, OMIM #193235). In homology modeling with other calpains, this R243L CAPN5 mutation was situated in a mobile loop that gates substrate access to the calcium-regulated active site. In in vitro activity assays, the mutation increased calpain protease activity and made it far more active at low concentrations of calcium. To test whether the disease allele could yield an animal model of ADNIV, we created transgenic mice expressing human (h) CAPN5R243L only in the retina. The resulting hCAPN5R243L transgenic mice developed a phenotype consistent with human uveitis and ADNIV, at the clinical, histological and molecular levels. The fundus of hCAPN5R243L mice showed enhanced autofluorescence (AF) and pigment changes indicative of reactive retinal pigment epithelial cells and photoreceptor degeneration. Electroretinography showed mutant mouse eyes had a selective loss of the b-wave indicating an inner-retina signaling defect. Histological analysis of mutant mouse eyes showed protein extravasation from dilated vessels into the anterior chamber and vitreous, vitreous inflammation, vitreous and retinal fibrosis and retinal degeneration. Analysis of gene expression changes in the hCAPN5R243L mouse retina showed upregulation of several markers, including members of the Toll-like receptor pathway, chemokines and cytokines, indicative of both an innate and adaptive immune response. Since many forms of uveitis share phenotypic characteristics of ADNIV, this mouse offers a model with therapeutic testing utility for ADNIV and uveitis patients. PMID:25994508

    To determine whether horses with clinically diagnosed Equine Recurrent Uveitis (ERU) and those with Leptospirosis infection have a specific cytokine profile in their aqueous humor (AH) and serum that differs from horses with uveitis secondary to other ocular inflammatory processes and from horses with normal eyes. Twenty-five client-owned horses with uveitis that were presented to the North Carolina State University Ophthalmology Service, and four University-owned horses without history or clinical signs of ocular disease. Samples of AH and serum were obtained from horses with ERU (n=13), acute or non-recurrent uveitis (UV; n=7), uveitis secondary to infectious keratitis (IK; n=5), and normal eyes (N; n=4). Cytokine levels in AH and serum were quantified using a multiplex bead immunoassay. Leptospiral antibody titers in serum and AH and PCR for Leptospiral DNA in AH were performed. In the AH of horses with ERU, increased levels of IL-1a, IL-4, IL-6, IL-8, IL-12p70, FGF-2, G-CSF, and RANTES were measured compared to UV, IK and N eyes, but the differences were not significant. However, IL-10 was significantly higher in ERU eyes compared to IK and N (P=0.029; 0.013), and IP-10 in ERU eyes was significantly higher than in UV and N (P=0.004). Furthermore, MCP-1 was significantly higher in ERU than N (P=0.04). In the serum, increased levels of IL-1a, IL-4, IL-6, IL-8, IL-12p70, fractalkine, and G-CSF were measured in horses with ERU, but the levels were not significantly higher than those observed in UV, IK, or N horses. However, serum IP-10 levels in horses with ERU were significantly higher than in UV and N horses (P=0.005) and MCP-1 levels were significantly higher in ERU than N (P=0.03). Horses with marked ocular inflammation had significantly higher serum levels of G-CSF, IL-1a, fractalkine, IL-13, IL-4, IL-17a, IL-12p70, IFN-γ, and MCP-1. Elevated IL-10 in AH was significantly associated with disease chronicity, both overall and in ERU eyes (P=0.049), and in

    Anterior chamber paracentesis is a valuable diagnostic tool in the management of uveitis, but may be underutilized because of concerns over its safety. We evaluated the safety profile of anterior chamber paracentesis performed at the slit lamp as an outpatient procedure. Retrospective, observational case series in a single tertiary centre. Five hundred and sixty patients with uveitis undergoing anterior chamber paracentesis. All anterior chamber paracenteses performed at the slit lamp for diagnostic or research purposes between January 1997 and June 2009 were analysed with regard to adverse events and pipet/syringe used. Procedures were included whether carried out on undilated or dilated pupils. Adverse events and serious adverse events. Out of 560 paracenteses, 510 were performed with a 27-gauge fixed-needle tuberculin syringe, and 50 using an O'Rourke aqueous pipet. All patients were prescribed a short course of topical antibiotic and examined post-procedure and 1-2 weeks later. Out of 560 procedures there were four complications (0.7%). Two patients had inadvertent injection of sterile air into the anterior chamber but with spontaneous resolution and no adverse outcome (O'Rourke pipet for both). One patient had anterior lens capsule touch that was self-sealing and left a tiny localized opacity (tuberculin syringe). One patient had an allergic reaction to povidone iodine. No patients reported pain, and there were no cases of iris trauma, entry site leak, hypotony, hyphaema or endophthalmitis. Anterior chamber paracentesis can be performed safely as an outpatient procedure at the slit lamp following adequate aseptic precaution, and appropriate counselling. © 2011 The Authors.

    To compare the benefits of fluocinolone acetonide implant therapy versus systemic corticosteroid therapy supplemented (when indicated) with immunosuppression for intermediate uveitis, posterior uveitis, and panuveitis. Additional follow-up of a randomized comparative effectiveness trial cohort. Two hundred fifty-five patients with intermediate uveitis, posterior uveitis, or panuveitis randomized to implant or systemic therapy. Best-corrected visual acuity (BCVA), visual field mean deviation (MD), activity of uveitis, and presence of macular edema (per reading center grading) ascertained prospectively. Trial participants were followed-up for 54 months from original randomization. The visual function trajectory in uveitic eyes demonstrated a similar (P = 0.73) degree of modest (not statistically significant) improvement from baseline to 54 months in both groups (mean improvement in BCVA at 54 months, 2.4 and 3.1 letters in the implant and systemic groups, respectively). Many had excellent initial visual acuity, limiting the potential for improvement. The mean automated perimetry MD score remained similar to baseline throughout 48 months of follow-up in both groups. Overall control of inflammation was superior in the implant group at every time point assessed (P < 0.016), although most eyes in the systemic therapy arm also showed substantial improvement, achieving complete control or low levels of inflammation. Although macular edema improved significantly more often with implant treatment within the first 6 months, the systemic group gradually improved over time such that the proportions with macular edema converged in the 2 groups by 36 months and overlapped thereafter (P = 0.41 at 48 months). Visual outcomes of fluocinolone acetonide implant and systemic treatment for intermediate uveitis, posterior uveitis, and panuveitis were similarly favorable through 54 months. The implant maintained a clear advantage in controlling inflammation through 54 months. Nevertheless

    Noninfectious uveitis (NIU) is a collection of intraocular inflammatory disorders that may be associated with significant visual impairment. To our knowledge, few studies have investigated NIU prevalence overall or stratified by inflammation location, severity, presence of systemic conditions, age, or sex. To estimate NIU prevalence using a large, retrospective, administrative claims database. This analysis used the OptumHealth Reporting and Insights database to estimate 2012 NIU prevalence. Analysis was conducted in September 2016. The large administrative insurance claims database includes 14 million privately insured individuals in 69 self-insured companies spanning diverse industries. Included in the study were patients with NIU with 2 or more uveitis diagnoses on separate days in 2012 and continuous enrollment in a health plan for all of 2012 and categorized by inflammation site. We estimated overall NIU prevalence by inflammation site, severity, sex, and age. Patients with anterior NIU were categorized by the presence of systemic conditions. Of the approximately 4 million eligible adult patients, approximately 2.1 million were women, and of the 932 260 children, 475 481 were boys. The adult prevalence of NIU was 121 cases per 100 000 persons (95% CI, 117.5-124.3). The pediatric NIU prevalence was 29 cases per 100 000 (95% CI, 26.1-33.2). Anterior NIU accounted for 81% (3904 cases) of adult NIU cases (98 per 100 000; 95% CI, 94.7-100.9) and 75% (207 cases) of pediatric NIU cases (22 per 100 000; 95% CI, 19.3-25.4). The prevalences of noninfectious intermediate, posterior, and panuveitis were, for adults, 1 (95% CI, 0.8-1.5), 10 (95% CI, 9.4-11.5), and 12 (95% CI, 10.6-12.7) per 100 000, respectively, and for pediatric patients, 0 (95% CI, 0.1-1.1), 3 (95% CI, 1.8-4.1), and 4 (95% CI, 2.9-5.6) per 100 000, respectively. The prevalence of NIU increased with age and was higher among adult females than males. Application of these estimates to the

    Tissue homeostasis results from a balance between cell proliferation and cell death by apoptosis. Estradiol affects proliferation as well as apoptosis in hormone-dependent tissues. In the present study, we investigated the apoptotic response of the anterior pituitary gland to lipopolysaccharide (LPS) in cycling female rats, and the influence of estradiol in this response in ovariectomized (OVX) rats. The OVX rats were chronically estrogenized with implanted Silastic capsules containing 1 mg of 17beta-estradiol (E2). Cycling or OVX and E2-treated rats were injected with LPS (250 microg/rat ip). Apoptosis was determined by the terminal deoxynucleotidyl-mediated dUTP nick-end labeling (TUNEL) method in sections of the anterior pituitary gland and spleen. Chronic estrogenization induced apoptosis in the anterior pituitary gland. Acute endotoxemia triggered apoptosis of cells in the anterior pituitary gland of E2-treated rats but not of OVX rats. No differences were observed in the apoptotic response to LPS in spleen between OVX and E2-treated rats. The apoptotic response of the anterior pituitary to LPS was variable along the estrous cycle, being higher at proestrus than at estrus or diestrus I. Approximately 75% of the apoptotic cells were identified as lactotropes by immunofluorescence. In conclusion, our results indicate that estradiol induces apoptosis and enables the proapoptotic action of LPS in the anterior pituitary gland. Also, our study suggests that estrogens may be involved in anterior pituitary cell renewal during the estrous cycle, sensitizing lactotropes to proapoptotic stimuli.

    Experimental uveitis features distinct hyperlipoperoxidation in damaged eye tissues, blood serum and the liver. The activity of antioxidant defense (AOD) enzymes decreases in tissues and blood of experimental animals whereas catalase compensatorily activates in hepatic tissue. Experimental therapy of uveitis with gentamycin and bacteriophage results in reducing hyperlipoperoxidation, increased activity of AOD enzymes but no complete normalization is observed. This manifested in preservation of inflammations to a certain degree.

    This study seeks to evaluate the clinical characteristics of spondyloarthritis (SpA)-related uveitis in a cohort from South China and to assess the efficacy and safety of therapies based on TNF blockers. SpA patients with uveitis admitted to a south China hospital were enrolled. Demographic information, clinical characteristics, laboratory findings, intraocular inflammation, visual acuity, macular thickness, and treatments were documented. Of the 1,036 SpA patients reviewed, 182 had uveitis. Ankylosing spondylitis (AS) was the most common subtype. Unilateral uveitis was found in 51 cases (51/182, 28.0%), and unilateral alternating uveitis was found in 75 cases (75/182, 41.2%). Half of the cases were recurrent uveitis (52.2%), and acute onset was common (76.4%). The most serious complication was vision loss (0.5%). No significant difference in disease activity was found between the SpA patients with or without uveitis. Predominant improvements were found in cases treated with all three anti-TNFs (infliximab, adalimumab, and etanercept) and anti-TNFs plus methotrexate (MTX). Monotherapy of methotrexate was not adequate for inducing remission. Monotherapy of etanercept was not as effective as adalimumab and infliximab, mainly in the prevention of recurrence. No significant difference in effectiveness was found among the three anti-TNFs if MTX was added. Etanercept plus MTX were well tolerated. Infliximab and adalimumab were associated with more tuberculosis and/or hepatitis flares. Uveitis is common in SpA patients. Severe complications may develop in prolonged and intractable cases. Treatments based on anti-TNFs had good clinical response, and better safety documentation were observed in etanercept plus MTX compared to the other two anti-TNF monoclonal antibodies plus MTX.

    Uveitis is one of the leading causes of blindness worldwide. Noninfectious uveitis may be associated with other systemic conditions, such as human leukocyte antigen B27-related spondyloarthropathies, inflammatory bowel disease, juvenile idiopathic arthritis, Behçet’s disease, and sarcoidosis. Conventional therapy with corticosteroids and immunosuppressive agents (such as methotrexate, azathioprine, mycophenolate mofetil, and cyclosporine) may not be sufficient to control ocular inflammation or prevent non-ophthalmic complications in refractory patients. Off-label use of biologic response modifiers has been studied as primary and secondary therapeutic agents. They are very useful when conventional immunosuppressive therapy has failed or has been poorly tolerated, or to treat concomitant ophthalmic and systemic inflammation that might benefit from these medications. Biologic therapy, primarily infliximab, and adalimumab, have been shown to be rapidly effective for the treatment of various subtypes of refractory uveitis and retinal vasculitis, especially Behçet’s disease-related eye conditions and the uveitis associated with juvenile idiopathic arthritis. Other agents such as golimumab, abatacept, canakinumab, gevokizumab, tocilizumab, and alemtuzumab may have great future promise for the treatment of uveitis. It has been shown that with proper monitoring, biologic therapy can significantly improve quality of life in patients with uveitis, particularly those with concurrent systemic symptoms. However, given high cost as well as the limited long-term safety data, we do not routinely recommend biologics as first-line therapy for noninfectious uveitis in most patients. These agents should be used with caution by experienced clinicians. The present work aims to provide a broad and updated review of the current and in-development systemic biologic agents for the treatment of noninfectious uveitis. PMID:24600203

    Over time, based on evidence-based medicine, a number of hormonal test levels including IGF-1 had been raised or lowered to meet new criteria standards. In particular, IGF-1 plasma levels have been shown in several studies to be an independent diagnostic tool in Adult Growth Hormone Deficiency (AGHD). Many endocrinology studies link low IGF-1 plasma levels with low levels of other anterior pituitary hormones (i.e., LH, FSH, and TSH). Low IGF-1 is considered by most to be between 84-100 µ/l and numerous studies recommend that raising IGF-1 to high normal range reverses Chronic Medical Diseases (CMD), improves bone mineral density (BMD), and fibromyalgia. Moreover, some studies suggest that low levels of IGF-1 by itself independent of anterior pituitary deficiencies is sufficient to determine AGHD in humans. In order to determine the relationship of low IGF-1 with that of LH, FSH, and TSH levels in subjects with CMD, we evaluated these levels (± SD) in 944 patients. Patients with IGF-1 below 84 µ/l, 100 µ/l, and 150 µ/l were accessed. 9.22% had less than 84 µ/l (SD ± 12.52); 19.9% had less than 100 µ/l (SD ± 9.54); and 51.6 had less than 150 µ/l (SD ± 26.0). Specifically, the percentages found for low LH, FSH, and TSH were only 4.2%, 4.8%, and 6.5%. We conclude that IGF-1 deficiencies occur independent of comorbid deficiencies of LH, FSH, and TSH. Finally, we propose that based on the present investigation, IGF-1 low levels between the range of 84-100 µ/l may be too low to be considered as an independent diagnostic marker to treat AGHD with CMD.

    Conclusions This technique is offered as a convenient and reliable method for cases with anterior TM perforation and inadequate anterior remnant. Objectives Chronic otitis media surgery is one of the most common procedures in otology. Anterior tympanic membrane (TM) perforation with inadequate anterior remnant is associated with higher rates of graft failure. It was the goal of this series to evaluate the anatomical and functional outcomes of a modified underlay myringoplasty technique-the anterior pull-through method. Materials and methods In a retrospective clinical study, 13 patients with anterior TM perforations with inadequate anterior remnants underwent tympanoplasty with anterior pull-through technique. The anterior tip of the temporalis fascia was pulled through and secured in a short incision lateral to the anterior part of the annulus. Data on graft take rate, pre-operative, and post-operative hearing status were analyzed. Results A graft success rate of 84.6% (11 out of 13) was achieved, without lateralization, blunting, atelectasia, or epithelial pearls. The air-bone gap was 21.5 ± 6.8 dB before intervention and 11.75 ± 5.7 dB after surgery (p = 0.003).

    In this paper, the authors describe a case of high serum levels of ubiquitin and proteasome in a woman under an acute attack of autoimmune uveitis. The woman was 52 years old, diagnosed as positive for the Human leukocyte antigen-B27 gene, and came to our observation in January 2013 claiming a severe uveitis attack that involved the right eye. During the acute attack of uveitis, this woman had normal serum biochemical parameters but higher levels of serum ubiquitin and proteasome 20S subunit, with respect to a healthy volunteer matched for age and sex. These levels correlated well with the clinical score attributed to uveitis. After the patient was admitted to therapy, she received oral prednisone in a de-escalation protocol (doses from 50 to 5 mg/day) for four weeks. Following this therapy, she had an expected reduction of clinical signs and score for uveitis, but concomitantly she had a reduction of the serum levels of ubiquitin, poliubiquitinated proteins (MAb-FK1) and proteasome 20S activity. Therefore, a role for ubiquitin and proteasome in the development of human autoimmune uveitis has been hypothesized. PMID:28245629

    Viruses have been demonstrated or suspected as the causative agents of various types of uveitis. Hepatitis B virus (HBV), apart from causing hepatitis, has also been implicated in the pathogenesis of systemic vasculitis, for example in glomerulonephritis and polyarteritis nodosa. It is therefore possible to postulate that a similar vasculitic process might occur in the eye leading to intraocular inflammation. A recent report from Switzerland suggests that HBV may be implicated in the aetiology of uveitis, as hepatitis B surface antigen (HBsAg) was found in the serum of 13% of cases of uveitis. Since the status of HBV in the aetiology of uveitis in Great Britain has not been investigated, we have examined serum from 200 cases of uveitis of various clinical types for the presence of circulating HBsAg. Only 4 cases (2%) were found to be HBsAg positive. This study failed, therefore, to confirm HBV as an important cause of uveitis in this country, but one cannot exclude the possibility that it may play a pathogenetic role in a small proportion of such cases.

    The history of cyclosporine and uveitis is intertwined with the development of experimental autoimmune uveitis (EAU) animal models and the understanding that T lymphocytes play a major role in the pathogenesis of uveitis. The early studies of CsA in uveitis also demonstrated the power of collaborative efforts in translational research. Dr. Robert Nussenblatt and his colleagues were the first to show that CsA can inhibit EAU. Over many years after the initial CsA experiments, Dr. Nussenblatt's group as well as others continued to study CsA under experimental conditions as well as in clinical trials with human patients. The data and observations from these studies significantly advanced our knowledge of uveitis pathophysiology and demonstrated the value of well-designed masked, controlled treatment trials in uveitis. Dr. Nussenblatt and his collaborators delved into the most significant adverse effect of CsA, renal toxicity, and helped elucidate the pathophysiology of renal injury. They explored adjunctive treatments to improve the efficacy and decrease the toxicity of CsA and also studied other members of the cyclosporine family. Among the immunosuppressives used to treat ocular inflammation, CsA was the first, and remains the only medication comprehensively studied under both experimental and clinical conditions.

    Purpose: This study investigates whether patients with viral hepatitis and cirrhosis are at risk of uveitis in the years following hepatitis. Methods: We used data from Taiwan National Health Insurance system. The cases were patients newly diagnosed with viral hepatitis from 2000 to 2011. The end point of interest was a diagnosis of uveitis. A chi-square test was used for the difference of demographic characteristics between viral hepatitis and comparison. The risk of uveitis in hepatitis was stratified using Cox proportional hazard regression. Results: We selected 17,389 patients with viral hepatitis and 34,778 matched comparison. The risk of uveitis in hepatitis cohort was 1.30-fold (95% confidence interval = 1.01–1.69). Patients with hepatitis B virus and hepatitis C virus coinfection had the highest risk (hazard ratio = 2.88; 95% confidence interval = 1.07–7.78), and followed by only hepatitis C virus infection (hazard ratio = 1.75; 95% confidence interval = 1.10–2.79). Patients with cirrhosis had a higher risk in the multivariable model but did not attach statistic difference. Conclusion: Patients with hepatitis B virus and hepatitis C virus coinfection had the highest risk of uveitis. In patients with hepatitis C virus and/or hepatitis B virus infection, the symptoms of uveitis should be alerted. Although these epidemiologic studies yielded informative results, the underlying mechanisms and the host's genetic factors remain to be investigated. PMID:27870801

    The clinical, angiographic, and histopathological features of experimental posterior uveitis in the black hooded Lister rat are described. This mild form of experimental allergic uveoretinitis (EAU) is induced by sensitisation with retinal S antigen in Freund's complete adjuvant, and the inflammation produced is confined to the posterior segment of the eye. This allows for the first time precise photographic and angiographic documentation of the evolution of clinical signs, because there is minimal clouding of the vitreous by inflammatory cells. Clinically the disease is characterised by the appearance of disc oedema and periphlebitis, followed by focal infiltrates in the deep retinal layers, with eventual atrophy of the pigment epithelium. Histologically, retinal vasculitis is associated with focal mononuclear cell infiltration and necrosis of the photoreceptor layers. This model closely resembles the clinical features of idiopathic retinal vasculitis seen in man. Images PMID:3651374

    Glaucoma is a potentially blinding complication of uveitis, where intraocular inflammation, secondary corticosteroid response, and varying types and degrees of angle abnormalities contribute to its pathogenesis. Management of uveitic glaucoma remains challenging. Treatment is targeted at reducing the inflammation and lowering the intraocular pressure. Recent studies have highlighted the role of viruses, such as cytomegalovirus, herpes simplex virus, and more recently Ebola virus, in the pathogenesis of uveitic glaucoma. Antiviral therapy may be beneficial in eyes with detectable viral DNA. The success of glaucoma surgery is decreased in eyes with uveitic glaucoma, and surgical interventions are associated with a higher incidence of postoperative complications. Novel glaucoma surgical and laser treatments may improve the predictability of surgery for uveitic glaucoma, but these require further evaluation.

    A diagnostic vitrectomy was performed on three patients with posterior uveitis of unknown origin and whose vitrous body was markedly affected. In all cases, cells of high-grade B-cell lymphoma (earlier referred to as reticulum cell sarcoma) were identified by cytological analysis of the specimen. In addition to the ocular findings, one of the three patients showed clinical and radiological evidence of a tumorous mass in the area of the right thalamus at the time of diagnosis. This was interpreted as a cerebral manifestation of the lymphoma. Initially, the other two patients did not show any cerebral involvement. One of them, however, developed clinical symptoms 9 months after diagnosis, which were radiologically verified as tumor infiltration of the cerebellum and the diencephalon. Under radiation therapy, the ocular findings disappeared within a few weeks.

Findings Skin biopsy revealed plenty of acid fast bacilli with a bacteriological index of 5 suggestive of multibacillary polar lepromatous leprosy. ASOCT revealed well-demarcated smooth-surfaced nodular lesion with internal hyporeflectivity corresponding to the areas of granuloma which decreased in size following treatment with antileprosy drugs and systemic and topical steroids. Conclusion ASOCT is a non-invasive technique to assess the extent of involvement of anterior segment in Hansen's disease and is a useful tool in follow-up. This is also the first report on ASOCT findings of iris granuloma in Hansen's disease. PMID:23514098

    To describe a case of unilateral intermediate uveitis, retained copper intraocular foreign body (IOFB) and fungus. Interventional case report. Brown-orange discoloration of the iris, lens and opacified vitreous was observed. Computed tomography revealed a retained IOFB, which was composed of copper. IOFB was removed during vitrectomy and cataract surgery. Copper deposition was demonstrated on the anterior capsule. Incidentally, dimorphic fungus were found in the vitreous. The presence of intraocular copper might have reduced the virulence of the fungus preventing endophthalmitis.

    Objective Axial spondyloarthritis (axial SpA) is characterized by inflammation of the spine and sacroiliac joints and can also affect extraarticular sites, with the most common manifestation being uveitis. Here we report the incidence of uveitis flares in axial SpA patients from the RAPID‐axSpA trial, including ankylosing spondylitis (AS) and nonradiographic (nr) axial SpA. Methods The RAPID‐axSpA (NCT01087762) trial is double‐blind and placebo‐controlled to week 24, dose‐blind to week 48, and open‐label to week 204. Patients were randomized to certolizumab pegol (CZP) or placebo. Placebo patients entering the dose‐blind phase were re‐randomized to CZP. Uveitis events were recorded on extraarticular manifestation or adverse event forms. Events were analyzed in patients with/without history of uveitis, and rates reported per 100 patient‐years. Results At baseline, 38 of 218 CZP‐randomized patients (17.4%) and 31 of 107 placebo‐randomized patients (29.0%) had past uveitis history. During the 24‐week double‐blind phase, the rate of uveitis flares was lower in CZP (3.0 [95% confidence interval (95% CI) 0.6–8.8] per 100 patient‐years) than in placebo (10.3 [95% CI 2.8–26.3] per 100 patient‐years). All cases observed during the 24‐week double‐blind phase were in patients with a history of uveitis; in these patients, rates were similarly lower for CZP (17.1 [95% CI 3.5–50.1] per 100 patient‐years) than placebo (38.5 [95% CI 10.5–98.5] per 100 patient‐years). Rates of uveitis flares remained low up to week 96 (4.9 [95% CI 3.2–7.4] per 100 patient‐years) and were similar between AS (4.4 [95% CI 2.3–7.7] per 100 patient‐years) and nr‐axial SpA (5.6 [95% CI 2.9–9.8] per 100 patient‐years). Conclusion The rate of uveitis flares was lower for axial SpA patients treated with CZP than placebo during the randomized controlled phase. Incidence of uveitis flares remained low to week 96 and was comparable to rates reported

    PURPOSE: To determine whether vitrectomy instrumentation improved outcomes when vitreous loss occurred during either extracapsular cataract extraction (ECCE) or phacoemulsification (PE) with posterior chamber lens implantation (PCIOL). METHODS: A consecutive series of ECCE + PCIOL (group 1: 1985-1989) and PE + PCIOL (group 2: 1993-1997) surgeries by a single surgeon was reviewed retrospectively. RESULTS: In group 1, 14 of 647 patients (2.2%) and in group 2, 9 of 665 patients (1.4%) experienced vitreous loss. In group 1, final visual acuity averaged 20/83; in group 2, 20/25 (P = .005). Average follow-up was 5.7 years (group 1) and 3.2 years (group 2). Uveitis, glaucoma, corneal problems, and retinal problems were assessed. CONCLUSIONS: Anterior vitrectomy reduced complications from vitreous loss. Fewer vitreous losses occurred with PE than ECCE. Patients with vitreous loss after PE attained better vision.

    There is not yet a commonly accepted, standardized approach in the treatment of juvenile idiopathic uveitis when initial steroid therapy is insufficient. We sought to assess current practice patterns within a large cohort of children with juvenile uveitis. This is a cross-sectional cohort study of patients with uveitis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRAnet) registry. Clinical information including, demographic information, presenting features, disease complications, and medications were collected. Chi-square and Fisher's exact tests were used to assess for associations between medications and clinical characteristics. Ninety-two children with idiopathic and 656 with juvenile idiopathic arthritis (JIA)-associated uveitis were identified. Indication (arthritis or uveitis) for medication use was not available for JIA patients; therefore, detailed analysis was limited to children with idiopathic uveitis. In this group, 94 % had received systemic steroids. Methotrexate (MTX) was used in 76 % of patients, with oral and subcutaneous forms given at similar rates. In multivariable analysis, non-Caucasians were more likely to be treated initially with subcutaneous MTX (P = 0.003). Of the 53 % of patients treated with a biologic DMARD, all received a tumor necrosis factor (TNF) inhibitor. TNF inhibitor use was associated with a higher frequency of cataracts (52 % vs 21 %; P = 0.001) and antinuclear antibody positivity (49 % vs 29 %; P = 0.04), although overall complication rates were not higher in these patients. Among idiopathic uveitis patients enrolled in the CARRAnet registry, MTX was the most commonly used DMARD, with subcutaneous and oral forms equally favored. Patients who received a TNF inhibitor were more likely to be ANA positive and have cataracts.

    To determine the role of the QuantiFERON-TB Gold In-Tube (QFT) (Cellestis Inc., Carnegie, Australia) assay in the diagnosis of tuberculosis (TB) uveitis. Retrospective cohort study. The study included 157 patients with suspected TB uveitis seen over an 18-month period (August 1, 2006, to February 31, 2007) at the Singapore National Eye Center (SNEC) uveitis clinic. We identified all cases of suspected TB uveitis in the above-mentioned time period and reviewed all medical records of the cases. Clinical findings, type of treatment instituted, response to treatment, and results of investigations such as QFT, tuberculin skin test (TST), and chest x-rays were recorded. A novel method of using treatment response to determine the presumed diagnosis of TB was used to estimate the accuracy of QFT and TST. The positive likelihood ratio (LR+), negative likelihood ratio (LR-), and area under the receiver operator characteristic curve (ROC) of the investigations were estimated. QFT is not superior to the TST in sensitivity as a screening test or first-line study in TB-related uveitis; however, QFT is more specific than the TST in identifying infections by Mycobacterium tuberculosis. Negative QFT tests should be interpreted with caution, because they do not exclude the diagnosis. The new QFT is only slightly superior to the TST in the diagnosis of TB uveitis. Thus, there is an important role for interpreting the QFT together with the TST. This is the first and largest study of its kind to evaluate the use of QFT in the clinical diagnosis of TB uveitis.

    The diagnostic workup of uveitis is a challenge due to the wide range of diagnoses and the lack of a well-codified diagnostic procedure. We aimed to evaluate the relevance of diagnostic investigations for the etiological diagnosis of uveitis. Retrospective cohort study of patients referred for etiological diagnosis of uveitis. Uveitis related to ophthalmological diseases or occurring during the course of previously diagnosed diseases were not included. Three hundred patients were included. Chest CT-scan was suggestive of sarcoidosis in 83 (29%). Features associated with abnormal CT-scan were: snowballs and/or peripheral multifocal choroiditis (PMC) upon ocular examination (P=0.004), blood lymphopenia (P<0.0001), angiotensin converting enzyme (ACE) level>1.5 ULN (P=0.0003). Bronchoscopy showed granuloma in 18 (11%) while alveolar lymphocytosis suggestive of sarcoidosis was reported in 45 (27%). Presence of granuloma on bronchial biopsies was always associated with chest CT-scan abnormalities, whereas 31% of patients with alveolar lymphocytosis had normal CT-scans. Features associated with contributive bronchoscopy were: snowballs and/or PMC (P=0.003), ACE>1.5 ULN (P=0.007), abnormal chest-CT scan (P<0.0001). Salivary gland biopsy revealed granuloma in 12 patients (5%). Cerebral MRI was abnormal in 15 patients (9%) who mostly presented with snowballs and/or retinal vasculitis. Finally, the main causes of uveitis were latent tuberculosis (25%) and sarcoidosis (22%), but 34% remained of undetermined origin. Uveitis relapses were observed in 31% and did not differ between patients with an identified diagnosis and those with idiopathic uveitis. Identification of factors associated with abnormal investigations might improve the optimal diagnostic workup adapted to each patient. Copyright © 2017 Elsevier B.V. All rights reserved.

We used the Standardization of Uveitis Nomenclature Working Group to classify uveitis, disease activity, and treatment end points. We enrolled 56 patients and 102 affected eyes. The mean age at diagnosis was 10 ± 3.5 years (range 3-15), and the mean follow-up 4.2 ± 3.3 years (1-15). The main diagnoses were idiopathic (55%), Behçet disease (15%), and sarcoidosis (5%). The main localization was panuveitis in 44 of 102 eyes (43%). Corticosteroid sparing treatment was needed in 62 of 102 eyes (60%). Second-line therapies included methotrexate and azathioprine, and the third-line therapy was a biologic agent, mainly infliximab, in 33 of 102 eyes (32%). Infliximab achieved uveitis inactivity in 14 of 18 eyes (80%), in all etiologies. Severe complications were present in 68 of 102 eyes (67%). The most common were synechiae 33% of eyes, cataract (20%), and macular edema (25%). Of these, 37% were present at diagnosis. Remission was achieved in 22 of 102 eyes (21%). Conventional therapies were insufficient to treat many of the cases of posterior or panuveitis. This study underlines the need for earlier and more aggressive treatment and antitumor necrosis factor-α therapy was rapidly efficient in most cases of refractory uveitis.

    Supramolecular nanofibers of prodrugs hold advantages for drug release due to their high drug payload, sustained and constant drug release behavior, and stimuli responsiveness. In this study, we report on a supramolecular hydrogel mainly formed by a clinically used drug triamcinolone acetonide (TA). Such a hydrogel could only be prepared via an ester bond hydrolysis process from its prodrug of succinated triamcinolone acetonide (STA). The resulting hydrogel could constantly release TA in the in vitro release experiment. The TA hydrogel possessed an excellent transscleral penetration ability, as evaluated by the in vitro transscleral transport study. The developed TA hydrogel also exhibited a great ocular compatibility in rats, as indicated by the optical coherence tomography (OCT) images, HE observation, and glial fibrillary acidic protein (GFAP) and vimentin immuno-staining assays of the retinas. Our TA hydrogel showed a decreased efficacy to inhibit ocular inflammation in the rat's experiment autoimmune uveitis (EAU) model compared to the commercial TA suspension (Transton®), but without causing complications such as high intraocular pressure and cataracts. These promising properties of the hydrogel indicated its great potential for the treatment of eye diseases.Supramolecular nanofibers of prodrugs hold advantages for drug release due to their high drug payload, sustained and constant drug release behavior, and stimuli responsiveness.

    Neutrophils have been recognized as critical response cells during the pathogenesis of endotoxin‑induced uveitis (EIU). Apoptosis of neutrophils induced by roscovitine has previously been demonstrated to ameliorate inflammation in several in vivo models. The present study aimed to assess whether roscovitine ameliorates EIU. EIU was induced in female C57BL/6 mice by a single intravitreal injection of lipopolysaccharide (LPS; 250 ng). The mice were divided into three groups as follows: LPS alone, LPS plus vehicle, LPS plus roscovitine (50 mg/kg). The mice were euthanized 12, 24, 48 and 72 h after LPS‑induced uveitis. Accumulation of inflammatory cells in the vitreous body was confirmed by immunohistochemistry, and quantified following hematoxylin and eosin staining. Terminal deoxynucleotidyl transferase dUTP nick‑end labeling was performed to detect of apoptotic cells. The mRNA levels of inflammatory cytokines were analyzed by reverse transcription‑quantitative polymerase chain reaction and the changes in protein levels were analyzed by western blotting. Inflammatory cells accumulated in the vitreous near the optic nerve head and the quantity peaked at 24 h after LPS injection. Immunohistochemistry revealed that the majority of the inflammatory cells were neutrophils. The number of infiltrating cells was similar in the LPS and LPS plus vehicle groups, while there were significantly less in the roscovitine group at 24 h. Apoptosis of neutrophils was observed between 12 and 48 h after roscovitine injection, while no apoptosis was observed in the other groups. The mRNA expression levels of GMCSF, CINC‑1 and ICAM‑1 peaked at 12 h after LPS injection, and decreased to normal levels at 72 h. This trend in mRNA expression was similar in the LPS and LPS plus vehicle groups; however, the expression levels decreased more quickly in the roscovitine group at 24 and 48 h. Following roscovitine administration, upregulated cleaved caspase 3 expression levels

    Uveitis is a clinical feature of the Blau syndrome, a disease linked to CARD15 (also referred to as NOD2) mutations. Three main mutations in this gene (R334W, R334Q and L469F) have been reported as Blau syndrome risk factors, a disease that manifests uveitis as one of its clinical features. However, little is known on the involvement of this gene in idiopathic uveitis. We thus sought to determine the frequency of these Blau-related CARD15 mutations in a cohort of Spanish patients with idiopathic uveitis. To this aim, 110 patients with idiopathic uveitis, followed at the Department of Ophtalmology of a tertiary hospital (Hospital Universitario Alcalá de Henares, Madrid. Spain) were enrolled. As a control population, 104 healthy subjects were used. DNA was extracted from blood samples and the Blau-related CARD15 mutations were analysed either by PCR-RFLP or direct DNA sequencing. None of the mutations studied was found in any of the individuals tested, whether diseased or healthy. It seems thus that Blau syndrome-related CARD15 mutations are not involved in idiopathic uveitis, a finding which allows us to suggest that the genetic aetiology of the idiopathic uveitis or the Blau-associated uveitis is different.
