  7. Evaluation of the Painful Eye.

    PubMed

    Pflipsen, Matthew; Massaquoi, Mariama; Wolf, Suzanne

    2016-06-15

    Eye problems constitute 2% to 3% of all primary care and emergency department visits. Common eye conditions that can cause eye pain are conjunctivitis, corneal abrasion, and hordeolum, and some of the most serious eye conditions include acute angle-closure glaucoma, orbital cellulitis, and herpetic keratitis. The history should focus on vision changes, foreign body sensation, photophobia, and associated symptoms, such as headache. The physical examination includes an assessment of visual acuity and systematic evaluation of the conjunctiva, eyelids, sclera, cornea, pupil, anterior chamber, and anterior uvea. Further examination with fluorescein staining and tonometry is often necessary. Because eye pain can be the first sign of an ophthalmologic emergency, the physician should determine if referral is warranted. Specific conditions that require ophthalmology consultation include acute angle-closure glaucoma, optic neuritis, orbital cellulitis, scleritis, anterior uveitis, and infectious keratitis.

    AIMS--The study was set up to evaluate the effect of microwave cyclodestruction on human eyes. METHODS--Two human eyes were studied. For treatment a horn shaped 5.8 GHz microwave applicator and fibre optic thermometry were used. Just before enucleation, the rectangular (2 x 3 mm) microwave aperture was placed onto the conjunctiva at a position 1-2 mm posterior to the corneal scleral limbus. Each of three to four treatment spots was targeted to receive a thermal dose of 54 degrees C for 1 minute. Clinical, gross, and histopathological evaluations were performed. RESULTS--Clinical evaluations of the treatment sites (immediately after microwave application) revealed no evidence of conjunctival or scleral damage. Trace fluorescein 2% uptake was noted within the targeted zones. The first eye was sectioned along the equatorial axis. Examination of the ciliary body and pars plana revealed whitening of the ciliary processes and depigmentation. Histopathological evaluations revealed ciliary epithelial necrosis with pigment dispersion. The vascularity of the ciliary processes showed focal disruption and haemorrhage. The underlying ciliary muscle and sclera appeared to be unaffected. No other findings could be attributed to microwave cyclodestruction. CONCLUSION--The results of this phase I toxicity study suggest that microwave heating can be used to damage preferentially the epithelial layers of the human ciliary body. Images PMID:7662635

    Purpose: 2-hydroxy estradiol (2-OHE2) is a catechol derivative of 17β -Estradiol (E2) and it is synthesized from E2 catalyzed by cytochrome P4501A1. Previous studies reported that 2-OHE2 is a physiologic antioxidant in lipoproteins, liver microsomes, and the brain. Catechol derivatives show an anti-inflammatory effect through the inhibition of prostaglandin endoperoxide synthase (PGS) activity. Corneal erosion caused by dry eye is related to an increase in oxidative stress and inflammation in ocular surface cells. We investigated the therapeutic effects of 2-OHE2 on corneal damage caused by dry eye. Methods: Steroidal radical scavenging activity was confirmed through the electron spin resonance (ESR) method. PGS activity was measured using the COX Fluorescent Activity Assay Kit. To evaluate the effect of 2-OHE2 on the treatment for dry eye, 2-OHE2 was applied as an eye drop experiment using dry eye model rats. Results: 2-OHE2 scavenged tyrosyl radical and possibly suppressed oxidative stress in corneal epithelial cells. In addition, 2-OHE2 inhibited PGS activity, and 2-OHE2 is probably a competitive inhibitor of PGS. Corneal PGS activity was upregulated in the dry eye group. Therefore, 2-OHE2 eye drops improved corneal erosion in dry eye model rats. Conclusions: 2-OHE2 is a candidate for the treatment of dry eye through the suppression of inflammation and oxidative stress in the cornea. PMID:27186071

    This study investigates the characteristics of eye movements during a camouflaged target search task. Camouflaged targets were randomly presented on two natural landscapes. The performance of each camouflage design was assessed by target detection hit rate, detection time, number of fixations on display, first saccade amplitude to target, number of fixations on target, fixation duration on target, and subjective ratings of search task difficulty. The results showed that the camouflage patterns could significantly affect the eye-movement behavior, especially first saccade amplitude and fixation duration, and the findings could be used to increase the sensitivity of the camouflage assessment. We hypothesized that the assessment could be made with regard to the differences in detectability and discriminability of the camouflage patterns. These could explain less efficient search behavior in eye movements. Overall, data obtained from eye movements can be used to significantly enhance the interpretation of the effects of different camouflage design. PMID:24139724

    Introduction Corneal blindness forms significant proportion of visual blindness in developing countries and penetrating keratoplasty (PK) can restore vision for this. The prognosis of PK is dependent on the corneal diseases responsible for corneal blindness. Aim To evaluate the indications and visual outcome of PK in tertiary eye care institute in Uttarakhand. Materials and Methods Data was reviewed from the medical records of 145 PK done in Department of Ophthalmology, Himalayan Institute of Medical Sciences from January 2012 to October 2014. Analysis of data was done for evaluation of the indications and visual outcome by Paired student’s t-test for hypothesis testing of grouped values of preoperative and last follow-up best corrected visual acuity in cases of optical and therapeutic grafts. A p-value < 0.05 was considered statistically significant. Results In this study data of 145 eyes of 138 patients was reviewed. The most common indication for keratoplasty was corneal scarring including adherent leucoma 48 (33.10%). Therapeutic keratoplasty was done for 33 cases with maximum 30(20.68%) cases of infectious keratitis. One case of tectonic graft was included in therapeutic keratoplasty group for analysis. There was statistically significant difference (p=.0001) in best corrected visual acuity improvement from 1.39 logMAR+ 0.022(SD) preoperatively to 0.367 logMAR+0.44(SD) postoperatively and 1.4 logMAR+.000(SD) preoperatively to 0.16 logMAR+0.57(SD) postoperatively for optical and therapeutic grafts respectively. Conclusion Infective keratitis either active or healed was the major indication for keratoplasty. Poor prognosis indications were most common in this part of the country. The visual outcome following corneal transplantation was encouraging particularly in cases of optical keratoplasty. PMID:27504319

    Many organizations and individuals prompted the authorization of the National Eye Institute by the United States Congress. The United States Marine Hospital and Public Health Service established a Laboratory of Hygiene in 1887, which became the research center of the National Institute of Health in 1930. The Albert D. and Mary Lasker Medical Foundation was mainly responsible for the 1945 conversion of the American Society for the Control of Cancer to the American Cancer Society, dedicated to medical research. Mildred Weisenfeld, a patient with retinitis pigmentosa, founded The Fight for Sight! in 1946 to provide funds for eye research. The Laskers invited Miss Weisenfeld to testify in support of a National Institute of Neurology, and her appeal was so persuasive that it emerged as the National Institute of Neurological Diseases and Blindness. Congressman John Fogarty and Senator Lister Hill directed the attention of the Congress and the public to the need for the Federal support of medical research. In 1960 Jules Stein, the legendary founder of the Music Corporation of America (MCA), established a new philanthropy, Research to Prevent Blindness, which provided skilled leadership in detailing the need for research in blinding disease and obtaining Congressional and Presidential approval of a new institute. The Committee for Research in Ophthalmology and Blindness was instrumental in bringing the groups interested in the welfare of the blind into harmony with groups concerned with medical research in blinding disease. The Association of University Professors of Ophthalmology was the first medical society to support the need for a National Eye Institute. The National Eye Institute was formally approved 8 August 1968 and celebrated its 25th anniversary in 1993. PMID:7555571

    Traditionally, the quality of the human vision is evaluated by a subjective test in which the examiner asks the patient to read a series of characters of different sizes, located at a certain distance of the patient. Typically, we need to ensure a subtended angle of vision of 5 minutes, which implies an object of 8.8 mm high located at 6 meters (normal or 20/20 visual acuity). These characters constitute what is known as the Snellen chart, universally used to evaluate the spatial resolution of the human eyes. The mentioned process of identification of characters is carried out by means of the eye - brain system, giving an evaluation of the subjective visual performance. In this work we consider the eye as an isolated image-forming system, and show that it is possible to isolate the function of the eye from that of the brain in this process. By knowing the impulse response of the eye´s system we can obtain, in advance, the image of the Snellen chart simultaneously. From this information, we obtain the objective performance of the eye as the optical system under test. This type of results might help to detect anomalous situations of the human vision, like the so called "cerebral myopia".

    Eye trauma results in 30,000 cases of blindness each year in the United States and is the second leading cause of monocular visual impairment. Eye injury is caused by a wide variety of projectile impacts and loading scenarios with common sources of trauma being motor vehicle crashes, military operations, and sporting impacts. For the current study, 79 experimental eye impact tests in literature were computationally modeled to analyze global and localized responses of the eye to a variety of blunt projectile impacts. Simulations were run with eight different projectiles (airsoft pellets, baseball, air gun pellets commonly known as BBs, blunt impactor, paintball, aluminum, foam, and plastic rods) to characterize effects of the projectile size, mass, geometry, material properties, and velocity on eye response. This study presents a matched comparison of experimental test results and computational model outputs including stress, energy, and pressure used to evaluate risk of eye injury. In general, the computational results agreed with the experimental results. A receiver operating characteristic curve analysis was used to establish the stress and pressure thresholds that best discriminated for globe rupture in the matched experimental tests. Globe rupture is predicted by the computational simulations when the corneoscleral stress exceeds 17.21 MPa or the vitreous pressure exceeds 1.01 MPa. Peak stresses were located at the apex of the cornea, the limbus, or the equator depending on the type of projectile impacting the eye. A multivariate correlation analysis revealed that area-normalized kinetic energy was the best single predictor of peak stress and pressure. Additional incorporation of a relative size parameter that relates the projectile area to the area of the eye reduced stress response variability and may be of importance in eye injury prediction. The modeling efforts shed light on the injury response of the eye when subjected to a variety of blunt projectile

    Objective: To evaluate the association of dry eye and vitiligo diseases with objective parameters and a questionnaire. Methods: The study was conducted in 30 vitiligo patients and 31 patients with non-complicated refractory complaints. All the patients underwent complete ophthalmologic examinations including fluorescein break-up time (FBU), corneal fluorescein staining (CFS) and Schirmer test-I. The dry eye status was evaluated by means of Ocular Surface Disease Index (OSDI). Results: The groups were similar regarding the age and gender distribution. The vitiligo group had higher OSDI scores (26.1±15.9 vs 14.7±5.4, t-test, p<0.001), shorter FBU (7.8±2.9 vs 9.8±2.2, Mann Whitney U test, p=0.005) and higher CFS positivity (18/30 vs 3/31, chi-square test, p<0.001) than control group. The groups were similar regarding the Meibomian Gland Dysfunction (MGD) and Schirmer test results. Fourteen (46.7%) of vitiligo patients had periocular involvement. The analysis within vitiligo patients revealed that FBU and Schirmer test were shorter in patients with periocular involvement, the OSDI scores and MGD status were similar. Conclusion: Our study suggest a possible association of dry eye and vitiligo diseases. The diagnostic tools for dry eye disease are in good correlation with each other. The OSDI questionnaire seems practical for both diagnostic purposes and follow-up. PMID:26150849

    Background and Aim: To evaluate the psychometric properties of the national Eye Institute refractive error correction quality of life questionnaire (NEI-RQL-42) among Iranian patients with refractive errors. Materials and Methods: Two samples of patients (n1 = 296, n2 = 95) were consecutively selected from the eye clinic of the Boo-Ali Hospital, Qazvin. A forward-backward procedure was conducted to translate and cross-culturally adapt the Iranian version of the NEI-RQL-42. A homogeneity, stability, and reliability test was conducted for the first sample after a two-week interval. Convergent validity was computed using the correlation between the NEI-RQL-42 subscale scores, National Eye Institute-Visual Functioning Questionnaire (NEI-VFQ-25), and the Short Form-36 (SF-36). Furthermore, Known-group analysis was performed, to determine the discriminant validity between the subgroups of patients with hyperopia, emmetropia, and myopia. Responsiveness to clinical change was tested by administering NEI-RQL-42 on the second sample that was scheduled for surgery. Results: Homogeneity was satisfactory with the Cronbach’s alpha coefficients ranging between 0.70 and 0.92. The 13 subscales of the NEI-RQL-42 showed a considerable stability in intra-class-correlation (ICC) ranging between 0.70 and 0.89. Positive correlation coefficients were found among all subscales of the NEI-RQL-42 and the other quality-of-life instruments (NEI-VFQ-25 and SF-36). The NEI-VFQ-25 displayed excellent discriminant validity to differentiate the subgroups of patients, and was found to be responsive to change after the surgical correction at three months. Conclusions: The Iranian version of the NEI-RQL-42 is a valid and reliable instrument to assess refractive error correction quality-of-life in Iranian patients. Moreover this questionnaire can be used to evaluate the effectiveness of interventions in patients with refractive errors. PMID:23772124

    Aim: To evaluate the profile of strabismus and amblyopia in patients presenting to a tertiary care institution in order to understand the disease burden. Materials and Methods: A retrospective, prospective hospital-based observational study was conducted at a tertiary level eye care hospital in India. All patients with strabismus or amblyopia who presented over a 1-year period were identified and referred to the squint clinic, where they were evaluated with a detailed clinical history and examination. Results: A total of 24475 patients were evaluated, of which 1950 had strabismus or amblyopia. The overall magnitude of amblyopia and strabismus was 2.0% [95% confidence interval (CI), 1.8-2.2)] and 6.9% (95% CI, 6.6-7.2), respectively. About 20% of those seeking an ophthalmic consultation were children and they constituted over half of the population referred to the squint clinic. Among younger children, the burden of amblyopia and strabismus was 84.4% and 26.6%, respectively. Among the referred patients, strabismus was noted in 84.6% (N = 1649), most of the cases of which was of the comitant subtype (78.1%, N = 1288) with an equal distribution of exotropia and esotropia. Paralytic [12.9% (N = 251)] and restrictive [4.7% (N = 85)] squint constituted the remaining burden of strabismus. Conclusion: Strabismus and amblyopia affect a sizeable proportion of patients presenting to a tertiary care ophthalmology setup. A significantly higher burden is present in the pediatric population. The majority of the cases of strabismus are of a comitant variety, which do not merit tertiary level eye care. There is a need to improve pediatric eye care at a secondary level to reduce the immense burden on tertiary referral centers. PMID:27051084

    Purpose To evaluate cataract surgery visual outcomes and associated risk factors in rural secondary level eye care centers of L V Prasad Eye Institute (LVPEI), India. Methods The Eye Health pyramid of LVPEI has a network of rural secondary care centres (SCs) and attached vision centres (VCs) that provide high quality comprehensive eye care with permanent infrastructure to the most disadvantaged sections of society. The most common procedure performed at SCs is cataract surgery. We audited the outcome of a random sample of 2,049 cataract surgeries done from October 2009-March 2010 at eight rural SCs. All patients received a comprehensive ophthalmic examination, both before and after surgery. The World Health Organization recommended cataract surgical record was used for data entry. Visual outcomes were measured at discharge, 1–3 weeks and 4–11 weeks follow up visits. Poor outcome was defined as best corrected visual acuity <6/18. Results Mean age was 61.8 years (SD: 8.9 years) and 1,133 (55.3%) surgeries were performed on female patients. Pre-existing ocular co-morbidity was present in 165 patients (8.1%). The most common procedure was small incision cataract surgery (SICS) with intraocular lens (IOL) implantation (91.8%). Intraoperative complications were seen in 29 eyes (1.4%). At the 4–11 weeks follow-up visit, based on presenting visual acuity (PVA), 61.8% had a good outcome and based on best-corrected visual acuity (BCVA), 91.7% had a good outcome. Based on PVA and BCVA, those with less than 6/60 were only 2.9% and 1.6% respectively. Using multivariable analysis, poor visual outcomes were significantly higher in patients aged ≥70 (OR 4.63; 95% CI 1.61, 13.30), in females (OR 1.58; 95% CI 1.04, 2.41), those with preoperative comorbidities (odds ratio 4.68; 95% CI 2.90, 7.57), with intraoperative complications (OR 8.01; 95% CI 2.91, 22.04), eyes that underwent no IOL or anterior chamber-IOL (OR 12.63; 95% CI 2.65, 60.25) and those undergoing extracapsular

    2015-01-01

    The National Eye Institute (NEI) hosted a workshop on May 2, 2015, as part of the Audacious Goals Initiative (AGI) to foster a concerted effort to develop novel therapies for outer retinal diseases. The central goal of this initiative is to “demonstrate by 2025 the restoration of usable vision in humans through the regeneration of neurons and neural connections in the eye and visual system.” More specifically, the AGI identified two neural retinal cell classes—ganglion cells and photoreceptors—as challenging, high impact targets for these efforts. A prior workshop and subsequent white paper provided a foundation to begin addressing issues regarding optic nerve regeneration, whereas the major objective of the May 2015 workshop was to review progress toward photoreceptor replacement and identify research gaps and barriers that are limiting advancement of the field. The present report summarizes that discussion and input, which was gathered from a panel of distinguished basic science and clinical investigators with diverse technical expertise and experience with different model systems. Four broad discussion categories were put forth during the workshop, each addressing a critical area of need in the pursuit of functional photoreceptor regeneration: (1) cell sources for photoreceptor regeneration, (2) cell delivery and/or integration, (3) outcome assessment, and (4) preclinical models and target patient populations. For each category, multiple challenges and opportunities for research discovery and tool production were identified and vetted. The present report summarizes the dialogue that took place and seeks to encourage continued interactions within the vision science community on this topic.

  7. Neuroimaging in the Diagnostic Evaluation of Eye Pain.

    PubMed

    Szatmáry, Gabriella

    2016-09-01

    Ocular or eye pain is a frequent complaint encountered not only by eye care providers but neurologists. Isolated eye pain is non-specific and non-localizing; therefore, it poses significant differential diagnostic problems. A wide range of neurologic and ophthalmic disorders may cause pain in, around, or behind the eye. These include ocular and orbital diseases and primary and secondary headaches. In patients presenting with an isolated and chronic eye pain, neuroimaging is usually normal. However, at the beginning of a disease process or in low-grade disease, the eye may appear "quiet," misleading a provider lacking familiarity with underlying disorders and high index of clinical suspicion. Delayed diagnosis of some neuro-ophthalmic causes of eye pain could result in significant neurologic and ophthalmic morbidity, conceivably even mortality. This article reviews some recent advances in imaging of the eye, the orbit, and the brain, as well as research in which neuroimaging has advanced the discovery of the underlying pathophysiology and the complex differential diagnosis of eye pain.

    Thirteen patients with varying degrees of Graves' ophthalmopathy were examined using high-resolution infrared oculography to determine peak velocities for horizontal eye movements between 3 degrees and 30 degrees. As severity of the orbital disease increased, peak velocities became substantially lower. Vertical-muscle surgery failed to have any effect on peak velocity of horizontal eye movements. In contrast, orbital decompression caused notable improvement in peak velocity of eye movements. Eye-movement recordings, which provide a measure of extraocular muscle function rather than structure, may provide a safe, sensitive, and accurate method for classifying and following up patients with Graves' ophthalmopathy.

    Background: Keshanjana (collyrium) is a well known Ayurvedic preparation prepared out of Keshamasi (ash prepared by scalp hairs) mixed with Goghrita (cow's ghee). This medicine is indicated for the treatment of Shushkakshipaka (dry eye syndrome) in the classical literature of Ayurveda; hence, it was under taken for standardization and clinical evaluation in an extra-mural research project from Central Council for Research in Ayurvedic Sciences, Department of AYUSH, New Delhi. Aim: To develop standard quality parameters for the Keshamasi, Keshanjana and Keshamasi ointment. Materials and Methods: Scalp hairs of male and females collected from saloons were converted to classical Masi Kalpana and mixed with cow ghee and petrolatum in the ratio of 1:5 to prepare the Keshanjana and Keshamasi ointment respectively. Standard Operation Procedure (SOP) were adopted and recorded accordingly. The raw material, furnished products and plain Goghrita were subjected for quality control parameters i.e., physico-chemical evaluation, anti-microbial study, particle size analysis, heavy metal analysis through inductive couple plasma spectroscopy with high performance thin layer liquid chromatography fingerprints. Results: Rancidity was negative in all the samples, indicating that the physico-chemical parameters are in acceptable range. Lead and zinc were present in most of the samples; while all samples are were free from microbial contamination. Conclusion: As no standards are available to compare the results of the current study, the observations cannot be compared. Thus the profile generated in the current study can be considered as standard to refer in future studies. PMID:25364202

    Minimally invasive surgical techniques for endoscope become widely used, for example, laparoscopic operation, NOTES (Natural Orifice Translumenal Endoscopic Surgery), robotic surgery and so on. There are so many demand and needs for endoscopic diagnosis. Especially, palpation is most important diagnosis on any surgery. However, conventional endoscopic system has no tactile sensibility. There are many studies about tactile sensor for medical application. These sensors can measure object at a point. It is necessary to sense in areas for palpation. To overcome this problem, we propose compound eye type tactile endoscope. The proposed system consists of TOMBO (Thin Observation Module by Bound Optics) and clear silicon rubber. Our proposed system can estimate hardness of target object by measuring deformation of a projected pattern on the silicon rubber. The purpose of this study is to evaluate the proposed system. At first, we introduce approximated models of the silicone and the object. We formulate the stiffness of object, the deformation of silicone, and the whole object. We investigate the accuracy of measured silicone's lower surface for deformation of silicone by prototype system. Finally, we evaluate the calculated stiffness of the soft object.

  11. Clinical Evaluation of Red Eyes in Pediatric Patients.

    PubMed

    Beal, Casey; Giordano, Beverly

    2016-01-01

    Patients with the primary symptom of a red eye are commonly seen in pediatric primary care clinics. The differential diagnoses of a red eye are broad, but with a succinct history and physical examination, the diagnosis can be readily identified in many patients. Identifying conditions that threaten vision and understanding the urgency of referral to an ophthalmologist is paramount. Some systemic diseases such as leukemia, sarcoidosis, and juvenile idiopathic arthritis can present with the chief symptom of a red eye. Finally, trauma, ranging from mild to severe, often precipitates an office visit with a red eye, and thus understanding the signs that raise concern for a ruptured globe is essential. In the primary care setting, with a focused history, a few simple examination techniques, and an appreciation of the differential diagnosis, one can feel confident in managing patients with acute red eyes.

    Thirty-nine patients took part in a double-blind, between-patient clinical trial to compare clobetasone butyrate, betamethasone phosphate, and placebo eye drops in the treatment of episcleritis. Although from the symptom scores the patients given placebo appeared to do as well as the other patients in the first week of treatment, they did significantly less well after this time. Clobetasone butyrate and betamethasone phosphate eye drops seemed to be equally effective in the treatment of this disease. PMID:7028088

    This article evaluates an eye-tracking device ("I Can Speak With My Eyes") designed for a museum exhibition. An eye-tracking system is designed not only for able individuals, but also for bedridden patients or physically handicapped people who intend to use computers. With one video CCD camera and frame grabber analyzing a series of images taken of the human pupil gazing at a screen, an auto-range-finding algorithm can be used to obtain the location of the pupil in real time. The computers will produce speech according to the location of where the eyes are gazing. In essence, the participants can speak with their eyes to achieve the advantages of learning and communicating. After the system was implemented, an experimental evaluation with innovation diffusion theory was conducted to survey users' feelings regarding the system. The implications of the evaluation findings are discussed to aid further research and education. PMID:22256667

    Aims: Prolonged contact lens wear is often accompanied by dryness of the eyes. The aim of this study was to compare conjunctival impression cytology (CIC) and tear film tests such as tear film break up time (TBUT) and Schirmer test for dry eye evaluation in contact lens wearers and measure their correlation with dry eye symptoms. Setting: A case control study was done at three referral eye centers. Materials and Methods: The eyes of 230 contact lens users were compared to 250 eyes of age- and sex-matched controls. Participants were recruited based on their response to a questionnaire of dry eye symptoms, (Dry Eye Scoring System, DESS©) and measurements of TBUT, Schirmer test, and CIC was done. A correlation analysis between symptom severity and tear film tests was performed. Pearson's coefficient, R2 > 0.5 was considered significant. Results: As compared to controls (r2 = 0.010), Nelson grade correlated significantly with dry eye symptoms (r2 = 0.765), among cases. However, there was moderate correlation between dry eye symptoms, Schirmer test, and TBUT (r2 = 0.557 and 0.530, respectively) among cases and a weak correlation among controls (r2 = 0.130 and 0.054, respectively). The sensitivity of TBUT was 86.4%, specificity was 82.4%, positive likelihood ratio (LR) was 4.50 [95% confidence interval (CI) 3.46-5.85)], and negative LR was 0.09. The sensitivity of the Schirmer test was 48.2%, specificity 88%, LR 2.12 (95% CI 1.48-2.96), and negative LR 0.83. Conclusion: CIC correlates better than Schirmer and TBUT with dry eye symptoms. It may be the most appropriate test for dry-eye evaluation in contact lens wearers. PMID:26811575

    Retinal hemorrhage is an important indicator of possible abusive head trauma, but it is also found in a number of other conditions. Distinguishing the type, number, and pattern of retinal hemorrhages may be helpful in establishing a differential diagnosis. Identification of ocular abnormalities requires a full retinal examination by an ophthalmologist using indirect ophthalmoscopy through a pupil that has been pharmacologically dilated. At autopsy, removal of the eyes and orbital tissues may also reveal abnormalities not discovered before death. In previously well young children who experience unexpected apparent life-threatening events with no obvious cause, children with head trauma that results in significant intracranial hemorrhage and brain injury, victims of abusive head trauma, and children with unexplained death, premortem clinical eye examination and postmortem examination of the eyes and orbits may be helpful in detecting abnormalities that can help establish the underlying etiology.

    AIM To develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25). METHODS NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA. RESULTS We recruited 379 patients, whose mean age was (54.5±15)y. Of 46.2% were males, 227 had cataract, 31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version (ARB-VFQ-25) were calculated. Internal consistency was high in all subscales (except general health), with Cronbach-α ranging from 0.702-0.911. Test-retest reliability was high (intraclass correlation coefficient 0.79). CONCLUSION ARB-VFQ-25 is a reliable and valid tool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination. PMID:25349812

    2008-01-01

    Purpose To evaluate the safety of Systane® Lubricant Eye Drops in relieving the symptoms of dry eye following laser-assisted in situ keratomileusis (LASIK) surgery. Methods This was a randomized, double-masked, single-center, placebo-controlled, contralateral eye study of 30 patients undergoing LASIK surgery. The mean age of patients was 42.4 ± 10.7 years, and the mean spherical equivalent was −3.29 (range, +1.75 to −7.38). Patients’ right and left eyes were randomized to receive either Systane® or placebo – a preserved, thimerosal-free saline solution – beginning from the day of surgery and ending 30 days following surgery. Outcome measures included tear film break up time (TFBUT), visual acuity, degree of corneal and conjunctival staining, and treatment-related adverse events. Results Preoperatively, placebo-treated eyes had statistically significantly higher sum corneal staining score than Systane®-treated eyes (p = 0.0464); however, the difference was clinically insignificant (p = 0.27). Two weeks post operatively, the average TFBUT in the Systane®-treated eyes was 1.23 seconds longer than that of the placebo-treated eyes (p = 0.028). All other evaluated variables were comparable between the two treatments. No adverse events were reported in the study. Conclusion Systane® Lubricant Eye Drops are safe for use following LASIK surgery to relieve the discomfort symptoms of dry eye associated with the procedure. PMID:19668456

    Purpose. This study aims to evaluate dry eye and ocular surface conditions of myopic teenagers by using questionnaire and clinical examinations. Methods. A total of 496 eyes from 248 myopic teenagers (7-18 years old) were studied. We administered Ocular Surface Disease Index (OSDI) questionnaire, slit-lamp examination, and Keratograph 5M. The patients were divided into 2 groups based on OSDI dry eye standard, and their ocular surfaces and meibomian gland conditions were evaluated. Results. The tear meniscus heights of the dry eye and normal groups were in normal range. Corneal fluorescein scores were significantly higher whereas noninvasive break-up time was dramatically shorter in the dry eye group than in the normal group. All three meibomian gland dysfunction parameters (i.e., meibomian gland orifice scores, meibomian gland secretion scores, and meibomian gland dropout scores) of the dry eye group were significantly higher than those of the normal group (P < 0.0001). Conclusions. The prevalence of dry eye in myopic teenagers is 18.95%. Meibomian gland dysfunction plays an important role in dry eye in myopic teenagers. The Keratograph 5M appears to provide an effective noninvasive method for assessing ocular surface situation of myopic teenagers. PMID:26881059

    2015-01-01

    Background Eye-tracking technology has been used to measure human cognitive processes and has the potential to improve the usability of health information technology (HIT). However, it is still unclear how the eye-tracking method can be integrated with other traditional usability methodologies to achieve its full potential. Objective The objective of this study was to report on HIT evaluation studies that have used eye-tracker technology, and to envision the potential use of eye-tracking technology in future research. Methods We used four reference databases to initially identify 5248 related papers, which resulted in only 9 articles that met our inclusion criteria. Results Eye-tracking technology was useful in finding usability problems in many ways, but is still in its infancy for HIT usability evaluation. Limited types of HITs have been evaluated by eye trackers, and there has been a lack of evaluation research in natural settings. Conclusions More research should be done in natural settings to discover the real contextual-based usability problems of clinical and mobile HITs using eye-tracking technology with more standardized methodologies and guidance.

    The mixed research design is a progressive methodological discourse that combines the advantages of quantitative and qualitative methods. Its possibilities of application are, however, dependent on the efficiency with which the particular research techniques are used and combined. The aim of the paper is to introduce the possible combination of Hypothesis with EyeTribe tracker. The Hypothesis is intended for quantitative data acquisition and the EyeTribe is intended for qualitative (eye-tracking) data recording. In the first part of the paper, Hypothesis software is described. The Hypothesis platform provides an environment for web-based computerized experiment design and mass data collection. Then, evaluation of the accuracy of data recorded by EyeTribe tracker was performed with the use of concurrent recording together with the SMI RED 250 eye-tracker. Both qualitative and quantitative results showed that data accuracy is sufficient for cartographic research. In the third part of the paper, a system for connecting EyeTribe tracker and Hypothesis software is presented. The interconnection was performed with the help of developed web application HypOgama. The created system uses open-source software OGAMA for recording the eye-movements of participants together with quantitative data from Hypothesis. The final part of the paper describes the integrated research system combining Hypothesis and EyeTribe. PMID:27087805

    2015-03-01

    This paper describes a low-cost noninvasive brain-computer interface (BCI) hybridized with eye tracking. It also discusses its feasibility through a Fitts' law-based quantitative evaluation method. Noninvasive BCI has recently received a lot of attention. To bring the BCI applications into real life, user-friendly and easily portable devices need to be provided. In this work, as an approach to realize a real-world BCI, electroencephalograph (EEG)-based BCI combined with eye tracking is investigated. The two interfaces can be complementary to attain improved performance. Especially to consider public availability, a low-cost interface device is intentionally used for test. A low-cost commercial EEG recording device is integrated with an inexpensive custom-built eye tracker. The developed hybrid interface is evaluated through target pointing and selection experiments. Eye movement is interpreted as cursor movement and noninvasive BCI selects a cursor point with two selection confirmation schemes. Using Fitts' law, the proposed interface scheme is compared with other interface schemes such as mouse, eye tracking with dwell time, and eye tracking with keyboard. In addition, the proposed hybrid BCI system is discussed with respect to a practical interface scheme. Although further advancement is required, the proposed hybrid BCI system has the potential to be practically useful in a natural and intuitive manner. PMID:25376041

    2009-01-01

    Half of eye injuries in the United States are caused by a blunt impact and more specifically, eye injuries effecting children often result from projectile shooting toys. The purpose of this study is to evaluate the risk of eye injuries of currently available projectile shooting toys. In order to assess the risk of each toy, a Facial and Ocular Countermeasure Safety (FOCUS) headform was used to measure the force applied to the eye during each hit for a total of 18 tests. The selected toys included a dart gun, a foam launcher, and a ball launcher. The force ranged from 4-93 N and was analyzed using the injury risk function for globe rupture for the FOCUS headform. Projectile characteristics were also examined using normalized energy to determine risk of corneal abrasion, hyphema, lens dislocation, retinal damage and globe rupture. It was found that the three toys tested produced peak loads corresponding with risk of globe rupture between 0% and 17.3%. The normalized energy results show no risk of hyphema, lens dislocation, retinal damage or globe rupture and a maximum risk of corneal abrasion of 5.9%. This study concludes that although there are many eye injuries caused by projectiles, the selected toys show a very low risk of eye injury. PMID:19369748

    AIM To assess quantitative changes of the macula in diabetic eyes after cataract surgery using optical coherence tomography (OCT) and to estimate the incidence of development or worsening of macular edema (ME) in diabetic eyes with or without pre-existing ME. METHODS In this prospective, observational study, 92 eyes of 60 diabetic patients who underwent cataract surgery were evaluated before surgery and 1, 3mo after surgery using OCT. Macular thickness was measured with OCT at nine macular subfields defined by the 9 zones early treatment of diabetic retinopathy study (ETDRS), as well as total macular volume obtained by OCT at 1, 3mo after surgery were compared with baseline features obtained before surgery. In addition, the incidence of development or worsening of ME was analyzed in diabetic eyes with or without pre-existing ME. RESULTS The central subfield mean thickness increased 21.0 µm and 25.5 µm at 1, 3mo follow-up, respectively (P<0.01). The average thickness of inner ring and outer ring increased 14.2 µm and 9.5 µm at 1mo, 18.2 µm and 12.9 µm at 3mo. Central-involved ME developed in 12 eyes at 3mo, including 4 eyes with pre-existing central-involved and 8 eyes with pre-existing non-central involved ME. Pre-existing diabetic macular edema (DME) was significantly associated with central-involved ME development (P<0.001). CONCLUSION A statistically significant increase could be detected in the central subfield as well as perifoveal and parafoveal sectors though the increase was mild. And eyes with pre-operative DME prior to cataract surgery are at higher risk for developing central-involved ME. PMID:26949615

    2015-04-01

    The VEGF protein (Vascular Endothelial Growth Factor) was identified in the '80s as a factor which induces proliferation of blood vessels in the body in general and in the retina in particular. Proliferative processes in retinal blood vessels, vascular permeability and induced edema which follows, frequently cause blindness in the diseases of the macula: AMD (Age-related Macular Degeneration) diabetes and retinal vascular occlusions. Since 2006, through treatment using anti-VEGF drugs--Avastin (Bevacizumab) and Lucentis (Ranibizumab) and Eylea (Aflibercept)--blindness in many patients in Israel and elsewhere was prevented. This paper reviews the treatment with anti-VEGF intraocular injections in the above mentioned diseases with reference to the growing activity at the Assuta Eye Institute. PMID:26065226

    Aim. To examine subscale and total scores of NEI-VFQ questionnaire of type 2 diabetes patients at different diabetic retinopathy (DRP) stages. Methods. A total number of 201 patients have been included. Prior to ophthalmological examination all patients participated in the NEI-VFQ questionnaire. The patients were divided into 5 groups according to the International Clinical Diabetic Retinopathy Disease Severity Scale (ICDRS). Results. The diabetes duration in general health scores (p = 0.029); the stage (p = 0.011); and clinically significant macular edema (CSME) (p = 0.019) in general vision were found to be the most efficient factors. In near vision activities the most efficient factors were near vision acuity (NVA) (p = 0.0001) and DRP stage (p = 0.020). EDTRS visual acuity was found to be the most efficient factor in vision specific role difficulties (p = 0.034) and dependency (p = 0.011) whereas Snellen visual acuity was found to be among the most effective factors in distance activities (DA) (p = 0.014) and total scores (p = 0.026). Discussion. Difference was based not on the diabetes duration, clinically significant cataract (CSCat), CSME presence, and DRP stage but on the visual acuity levels of the better seeing eye of the patients.

    1993-12-01

    We developed a "physical eye system" to evaluate visual impression after physical implantation of monofocal and multifocal intraocular lenses (IOLs). The system is constructed as two identical astronomical telescopes. The objectives imitate the cornea and behind this cornea the IOL is inserted. The image quality represents exactly the quality of the intraocular lens. PMID:8145490

    An in vitro eye irritation test battery (IVEye) composed of the EYTEX and Modified Agarose Diffusion Method (MADM) assays was evaluated for use as a predictive, economical screen and/or adjunct for the Draize eye test. EYTEX mimics corneal opacification using a synthetic matrix of proteins that is intended to produce measurable opacity on exposure to chemical irritants in proportion to their ocular irritation potential. MADM is a cytotoxicity-based assay consisting of NCTC clone 929 mouse fibroblasts overlayed with 1% agarose in culture medium. Potential eye irritation is measured macroscopically as the area of decolorization (neutral red release) around the area of chemical application and microscopically as the percentage of cell lysis resulting from chemical application. Of the 70 materials tested in the IVEye for which Draize eye test data also exist, the battery correctly identified 38 materials as non-irritants and 30 as irritants, with two false positives and no false negatives. Non-parametric analysis of the data show the battery to have a sensitivity of 100%, a specificity of 95% and a predictive value of 94%. The irritation class correlation (equivalence; irritation ranking) between EYTEX alone and the Draize data was 85%. These data support the use of IVEye as an accurate, reproducible and cost-effective in vitro method for identifying the eye irritation potential of petroleum products. PMID:20692994

  1. Remote control of mobile robots through human eye gaze: the design and evaluation of an interface

    NASA Astrophysics Data System (ADS)

    Controlling mobile robots remotely requires the operator to monitor the status of the robot through some sort of feedback. Assuming a vision based feedback system is used the operator is required to closely monitor the images while navigating the robot in real time. This will engage the eyes and the hands of the operator. Since the eyes are engaged in the monitoring task anyway, their gaze can be used to navigate the robot in order to free the hands of the operator. However, the challenge here lies in developing an interaction interface that enables an intuitive distinction to be made between monitoring and commanding. This paper presents a novel means of constructing a user interface to meet this challenge. A range of solutions are constructed by augmenting the visual feedback with command regions to investigate the extent to which a user can intuitively control the robot. An experimental platform comprising a mobile robot together with cameras and eye-gaze system is constructed. The design of the system allows control of the robot, control of onboard cameras and control of the interface through eye-gaze. A number of tasks are designed to evaluate the proposed solutions. This paper presents the design considerations and the results of the evaluation. Overall it is found that the proposed solutions provide effective means of successfully navigating the robot for a range of tasks.

    Biophotonic Sensing Cells (BICELLs) are demonstrated to be an efficient technology for label-free biosensing and in concrete for evaluating dry eye diseases. The main advantage of BICELLs is its capability to be used by dropping directly a tear into the sensing surface without the need of complex microfluidics systems. Among this advantage, compact Point of Care read-out device is employed with the capability of evaluating different types of BICELLs packaged on Biochip-Kits that can be fabricated by using different sensing surfaces material. In this paper, we evaluate the performance of the combination of three sensing surface materials: (3-Glycidyloxypropyl) trimethoxysilane (GPTMS), SU-8 resist and Nitrocellulose (NC) for two different biomarkers relevant for dry eye diseases: PRDX-5 and ANXA-11.

    Background The purpose of this study was to compare changes in corneal staining in patients with dry eye after 6 weeks of treatment with Systane® Gel Drops or Refresh Liquigel® lubricant eye drops. Methods Patients aged ≥18 years with a sodium fluorescein corneal staining sum score of ≥3 in either eye and best-corrected visual acuity of 0.6 logarithm of the minimum angle of resolution or better in each eye who were using a lubricant eye gel or ointment for dry eye were included in this randomized, parallel-group, multicenter, double-blind trial. Patients were randomized to four times daily Systane® Gel Drops (polyethylene glycol 400 0.4% and propylene glycol 0.3%) or Refresh LiquiGel® Drops (carboxymethylcellulose sodium 1%) for 6 weeks. The primary efficacy outcome was mean change from baseline to week 6 in sodium fluorescein corneal staining. Supportive efficacy outcomes included conjunctival staining, tear film break-up time, Patient Global Assessment of Improvement, Impact of Dry Eye on Everyday Life (IDEEL) Treatment Satisfaction/Treatment Bother Questionnaire, Single Symptom Comfort Scale, and Ocular Symptoms Questionnaire. The safety analysis comprised recording of adverse events. Results In total, 147 patients (Systane group, n=73; Refresh group, n=74; mean ± standard deviation age, 57±16 years) were enrolled and included in the safety and efficacy analyses. Corneal staining was significantly reduced from baseline to week 6 for Systane and Refresh (−3.4±2.5 and −2.5±2.6 units, respectively; P<0.0001, t-test), with a significantly greater improvement with Systane versus Refresh (P=0.0294). Results for conjunctival staining, tear film break-up time, and patient-reported outcome questionnaires were not statistically different between groups. No safety issues were identified; adverse events were reported by 19% of patients with Systane and 30% of patients with Refresh eye drops. Conclusion Systane Gel Drops were associated with significantly

    2015-01-01

    Background: Corneal collagen cross-linking (CXL) is gaining popularity as a treatment in arresting the progression of keratoconus. It is a relatively new therapy using ultraviolet-A (UVA) with a photosensitizer to increase corneal stiffness. The purpose of this study was to evaluate visual, keratometric and topographic outcomes after corneal CXL in progressive keratoconic eyes. Materials and Methods: In this prospective nonrandomized clinical study, 140 eyes of 110 patients with progressive keratoconus were treated by combined riboflavin/UVA CXL. Mean sphere, mean cylinder uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refractive spherical equivalent, corneal topography, pachymetry, and endothelial cell morphology were examined preoperatively and 12–24 months postoperatively. Results: The preoperative mean sphere was −3.33 ± 3.13 diopter (D) and decreased to −3.09 ± 3.09 D (P = 0.007). The preoperative mean cylinder was −4.05 ± 2.29 D and changed to −3.79 ± 2.23 D (P = 0.011). UDVA changed from 0.95 ± 0.64 logarithm of the minimum angle of resolution (logMAR) to 0.85 ± 0.59 logMAR (P = 0.003). Thirty-five eyes (25%) gained one or more lines of preoperative UDVA, 87 eyes (62.1%) did not change and 18 eyes (12.8%) lost one or more lines of the preoperative UDVA. CDVA in 80% of the patients remained stable (no lines lost). Statistical analysis of keratometry, pachymetry, and endothelial cell count did not show the significant difference after surgery. Conclusion: Our study showed improvement in visual and refractive results of the corneal CXL and confirmed that CXL is the safe and effective procedure. PMID:26605237

  8. Health systems analysis of eye care services in Zambia: evaluating progress towards VISION 2020 goals

    PubMed Central

    2014-01-01

    Background VISION 2020 is a global initiative launched in 1999 to eliminate avoidable blindness by 2020. The objective of this study was to undertake a situation analysis of the Zambian eye health system and assess VISION 2020 process indicators on human resources, equipment and infrastructure. Methods All eye health care providers were surveyed to determine location, financing sources, human resources and equipment. Key informants were interviewed regarding levels of service provision, management and leadership in the sector. Policy papers were reviewed. A health system dynamics framework was used to analyse findings. Results During 2011, 74 facilities provided eye care in Zambia; 39% were public, 37% private for-profit and 24% owned by Non-Governmental Organizations. Private facilities were solely located in major cities. A total of 191 people worked in eye care; 18 of these were ophthalmologists and eight cataract surgeons, equivalent to 0.34 and 0.15 per 250,000 population, respectively. VISION 2020 targets for inpatient beds and surgical theatres were met in six out of nine provinces, but human resources and spectacles manufacturing workshops were below target in every province. Inequalities in service provision between urban and rural areas were substantial. Conclusion Shortage and maldistribution of human resources, lack of routine monitoring and inadequate financing mechanisms are the root causes of underperformance in the Zambian eye health system, which hinder the ability to achieve the VISION 2020 goals. We recommend that all VISION 2020 process indicators are evaluated simultaneously as these are not individually useful for monitoring progress. PMID:24575919

  1. Ocular Surface Epithelial Thickness Evaluation in Dry Eye Patients: Clinical Correlations

    PubMed Central

    Liang, Qingfeng; Liang, Hong; Liu, Hanruo; Pan, Zhiqiang; Baudouin, Christophe; Labbé, Antoine

    2016-01-01

    Purpose. To evaluate the relationship between corneal and conjunctival epithelium thickness and ocular surface clinical tests in dry eye disease (DED) patients. Patients and Methods. Fifty-four patients with DED and 32 control subjects were included. Each patient underwent an ocular surface evaluation using the ocular surface disease index (OSDI), tear film break-up time (TBUT), corneal and conjunctival staining, tear film lipid layer analysis, and Schirmer test. The central corneal (CET), limbal (LET), and bulbar conjunctival epithelium thickness (BET) were acquired using spectral-domain optical coherence tomography (SD-OCT). Results. Compared to control subjects, mean BET was significantly thicker and mean LET was significantly lower in the DED group. There was no significant difference in mean CET between the two groups. The mean LET was correlated with OSDI and TBUT. The inferior LET was correlated with OSDI, Schirmer I test, TBUT, Oxford score, and corneal sensitivity. Mean BET was correlated with OSDI and TBUT, but not with Schirmer I test and Oxford score. Conclusions. In dry eye patients, a thinner limbal epithelium and a thicker bulbar conjunctival epithelium were observed. These changes were correlated to the severity of dry eye symptoms and tear film alterations. PMID:26925258

  2. Evaluation of Color Settings in Aerial Images with the Use of Eye-Tracking User Study

    Mirijovsky, J.; Popelka, S.

    2016-06-01

    The main aim of presented paper is to find the most realistic and preferred color settings for four different types of surfaces on the aerial images. This will be achieved through user study with the use of eye-movement recording. Aerial images taken by the unmanned aerial system were used as stimuli. From each image, squared crop area containing one of the studied types of surfaces (asphalt, concrete, water, soil, and grass) was selected. For each type of surface, the real value of reflectance was found with the use of precise spectroradiometer ASD HandHeld 2 which measures the reflectance. The device was used at the same time as aerial images were captured, so lighting conditions and state of vegetation were equal. The spectral resolution of the ASD device is better than 3.0 nm. For defining the RGB values of selected type of surface, the spectral reflectance values recorded by the device were merged into wider groups. Finally, we get three groups corresponding to RGB color system. Captured images were edited with the graphic editor Photoshop CS6. Contrast, clarity, and brightness were edited for all surface types on images. Finally, we get a set of 12 images of the same area with different color settings. These images were put into the grid and used as stimuli for the eye-tracking experiment. Eye-tracking is one of the methods of usability studies and it is considered as relatively objective. Eye-tracker SMI RED 250 with the sampling frequency 250 Hz was used in the study. As respondents, a group of 24 students of Geoinformatics and Geography was used. Their task was to select which image in the grid has the best color settings. The next task was to select which color settings they prefer. Respondents' answers were evaluated and the most realistic and most preferable color settings were found. The advantage of the eye-tracking evaluation was that also the process of the selection of the answers was analyzed. Areas of Interest were marked around each image in the

    Background The establishment of minor eye conditions schemes (MECS) within community optometric practices provides a mechanism for the timely assessment of patients presenting with a range of acute eye conditions. This has the potential to reduce waiting times and avoid unnecessary referrals to hospital eye services (HES). Objective To evaluate the clinical effectiveness, impact on hospital attendances and patient satisfaction with a minor eye service provided by community optometrists. Methods Activity and outcome data were collected for 12 months in the Lambeth and Lewisham MECS. A patient satisfaction questionnaire was given to patients at the end of their MECS appointment. A retrospective difference-in-differences analysis of hospital activity compared changes in the volume of referrals by general practitioners (GPs) from a period before (April 2011–March 2013) to after (April 2013–March 2015) the introduction of the scheme in Lambeth and Lewisham relative to a neighbouring area (Southwark) where the scheme had not been commissioned. Appropriateness of case management was assessed by consensus using clinical members of the research team. Results A total of 2123 patients accessed the scheme. Approximately two-thirds of patients (67.5%) were referred by their GP. The commonest reasons for patients attending for a MECS assessment were ‘red eye’ (36.7% of patients), ‘painful white eye’ (11.1%) and ‘flashes and floaters’ (10.2%). A total of 64.1% of patients were managed in optometric practice and 18.9% were referred to the HES; of these, 89.2% had been appropriately referred. First attendances to HES referred by GPs reduced by 26.8% (95% CI −40.5% to −13.1%) in Lambeth and Lewisham compared to Southwark. Conclusions The Lambeth and Lewisham MECS demonstrates clinical effectiveness, reduction in hospital attendances and high patient satisfaction and represents a successful collaboration between commissioners, local HES units and primary

    Graphene and its derivatives are the new carbon nanomaterials with the prospect for great applications in electronics, energy storage, biosensors and medicine. However, little is known about the toxicity of graphene or its derivatives in the case of occasional or repeated ocular exposure. We performed in vitro and in vivo studies to evaluate the toxicity of graphene oxide (GO) exposure to the eye. Primary human corneal epithelium cells (hCorECs) and human conjunctiva epithelium cells (hConECs) were exposed to GO (12.5-100 μg/mL). Acute GO exposure (2 h) did not induce cytotoxicity to hCorECs. However, short-term GO exposure (24 h) exerted significant cytotoxicity to hCorECs and hConECs with increased intracellular reactive oxygen species (ROS). Glutathione (GSH) reduced the GO-induced cytotoxicity. We further performed acute eye irritation tests in albino rabbits according to the Organization for Economic Cooperation and Development (OECD) guidelines, and the rabbits did not exhibit corneal opacity, conjunctival redness, abnormality of the iris, or chemosis at any time point after the instillation of 100 μg/mL of GO. However, 5-day repeated GO exposure (50 and 100 μg/mL) caused reversible mild corneal opacity, conjunctival redness and corneal epithelium damage to Sprague-Dawley rats, which was also alleviated by GSH. Therefore, our study suggests that GO-induced time- and dose-dependent cytotoxicity to hCorECs and hConECs via oxidative stress. Occasional GO exposure did not cause acute eye irritation; short-term repeated GO exposure generally resulted in reversible damage to the eye via oxidative stress, which may be alleviated by the antioxidant GSH.

    2016-01-01

    Purpose. To investigate the prevalence and characteristics of focal choroidal excavation (FCE) concurrent with central serous chorioretinopathy (CSC) using multimodal imaging. Methods. This was a retrospective single-institution study. Clinical features and multimodal imaging findings were analyzed in eyes with CSC and FCEs, using imaging methods including optical coherence tomography (OCT), OCT angiography (OCTA), fluorescein angiography (FA), indocyanine green angiography (ICGA), fundus autofluorescence (FAF), and multispectral imaging. Results. Seventeen patients (4.8%) with 21 FCEs (19 eyes) were found among 351 consecutive Chinese patients with CSC. Chronic CSC represented 47.1% of those cases. Window defects in 12 lesions identified through FA and hypoautofluorescence in 13 lesions identified through FAF revealed retinal pigment epithelial attenuation. Choroidal hemodynamic disturbances characterized by localized filling defects at the excavation and circumferential hyperperfusion were validated by both ICGA and OCTA, which were similar to the angiographic features of normal chronic CSC. The hyperreflective tissue beneath FCE, observed on B-scan OCT, presented as intensive choroidal flow signals on OCTA. Conclusions. FCE is not uncommon in patients with CSC. Multimodal imaging suggested that the aberrant choroidal circulation might be a contribution factor for leakage from the dysfunctional retinal pigment epithelium at the area of excavation.

    2009-01-01

    Performance enhancements associated with selected forms of automation were quantified in a recent human-in-the-loop evaluation of two candidate operational concepts for fault management on next-generation spacecraft. The baseline concept, called Elsie, featured a full-suite of "soft" fault management interfaces. However, operators were forced to diagnose malfunctions with minimal assistance from the standalone caution and warning system. The other concept, called Besi, incorporated a more capable C&W system with an automated fault diagnosis capability. Results from analyses of participants' eye movements indicate that the greatest empirical benefit of the automation stemmed from eliminating the need for text processing on cluttered, text-rich displays.

    A C-band erbium doped fiber ring laser is proposed and investigated. With the use of two sub-ring cavities and a saturable absorber, a high quality and stable fiber ring laser is obtained for high optical signal to noise ratio operation in lightwave transmission. As different fiber Bragg gratings are employed as the wavelength filter, a narrow 3 dB-bandwidth is necessary for the high quality operation. The fiber ring laser is evaluated in lightwave transmission. The Q factor and eye diagrams are also measured and discussed.

    The use of parenteral antibiotic eye drop formulations with non-marketed compositions or concentrations, commonly called fortified antibiotic eye drops, is a common practice in Ophthalmology in the hospital setting. The aim of this study was to evaluate the in vitro ocular toxicity of the main fortified antibiotic eye drops prepared in the Hospital Pharmacy Departments. We have conducted an in vitro experimental study in order to test the toxicity of gentamicin, amikacin, cefazolin, ceftazidime, vancomycin, colistimethate sodium and imipenem-cilastatin eye drops; their cytotoxicity and acute tissue irritation have been evaluated. Cell-based assays were performed on human stromal keratocytes, using a cell-based impedance biosensor system [xCELLigence Real-Time System Cell Analyzer (RTCA)], and the Hen's Egg Test for the ocular irritation tests. All the eye drops, except for vancomycin and imipenem, have shown a cytotoxic effect dependent on concentration and time; higher concentrations and longer exposure times will cause a steeper decline in the population of stromal keratocytes. Vancomycin showed a major initial cytotoxic effect, which was reverted over time; and imipenem appeared as a non-toxic compound for stromal cells. The eye drops with the highest irritating effect on the ocular surface were gentamicin and vancomycin. Those antibiotic eye drops prepared at the Hospital Pharmacy Departments included in this study were considered as compounds potentially cytotoxic for the ocular surface; this toxicity was dependent on the concentration used.

    The eye irritation potential of drug candidates or pharmaceutical ingredients should be evaluated if there is a possibility of ocular exposure. Traditionally, the ocular irritation has been evaluated by the rabbit Draize test. However, rabbit eyes are more sensitive to irritants than human eyes, therefore substantial level of false positives are unavoidable. To resolve this species difference, several three-dimensional human corneal epithelial (HCE) models have been developed as alternative eye irritation test methods. Recently, we introduced a new HCE model, MCTT HCETM which is reconstructed with non-transformed human corneal cells from limbal tissues. Here, we examined if MCTT HCETM can be employed to evaluate eye irritation potential of solid substances. Through optimization of washing method and exposure time, treatment time was established as 10 min and washing procedure was set up as 4 times of washing with 10 mL of PBS and shaking in 30 mL of PBS in a beaker. With the established eye irritation test protocol, 11 solid substances (5 non-irritants, 6 irritants) were evaluated which demonstrated an excellent predictive capacity (100% accuracy, 100% specificity and 100% sensitivity). We also compared the performance of our test method with rabbit Draize test results and in vitro cytotoxicity test with 2D human corneal epithelial cell lines. PMID:26157556

    Publishing clinical guidelines (GLs) on the web increases their accessibility. However, evaluating their usability and understanding how users interact with the websites has been neglected. In this study we used Tobii eye-tracker to analyse users' interaction with five commercial and public GL sites popular in Norway (four in Norwegian and one English of US origin (UpToDate)). We measured number of clicks and usage rate for search functions, task completion time, users' objective and perception of task success rate. We also measured learning effect for inexperienced users. We found a direct correlation between participant's satisfaction regarding website usability and the time spent, number of mouse clicks and use of search function to obtain the desired results. Our study showed that users' perceived success rate was not reliable and GL publishers should evaluate their website regarding presentation format, layout, navigation bar and search function.

    Purpose The goal of the present study is to develop a poly (ethylene oxide) N10 (PEO N10) based melt-cast matrix system for efficient and prolonged delivery of hesperetin (HT), a promising bioflavonoid, to the posterior segment of the eye through the topical route. Methods HT film was prepared by melt-cast method using PEO N10 and cut into 4 mm × 2 mm segments, each weighing 8 mg. This film was evaluated with respect to in vitro release rates and also transmembrane delivery across Spectra/Por® membrane (MWCO: 10000 Daltons) and isolated rabbit corneas. Ocular tissue concentrations were also determined post application of the film in ex vivo and in vivo models. Results HT release from the film was determined to be about 95.3 % within 2 h. In vitro transcorneal flux was observed to be 0.58 ± 0.05 μg/min/cm2 across the isolated rabbit cornea. High levels of HT were detected in the retina-choroid (RC) and vitreous humor (VH) in the ex vivo model following topical application of the film. Significant levels of HT were observed in both anterior and posterior segment ocular tissues 1h post topical application of the 10 and 20 %w/w HT films on the rabbit eye. Moreover, HT was detected in the VH and RC even after 6h following topical application of the film in vivo. Conclusion The results from this study suggest that the melt-cast films can serve as a viable platform for sustained topical delivery of bioflavonoids, and other therapeutic agents, into the back-of-the eye tissues.

    For a few years, health institutions have had to comply with the certification and the need to establish the new governance. Thanks to the accreditation version 2 (obtained in 2005), the elaboration of the hospital project (adopted in October, 2006) and the organization in poles since 2006, the quality oriented management became a priority axis at the University Hospital of Angers. The strategic adaptation to quality requirements leads to develop the hospital management, more especially at the level of the clinical, medico technical and administrative poles. The elements of the hospital project including the part about the quality, risk and evaluation aim at being adapted by every pole according to the level of its project. This adaptation which is imposed to each pole manager requires a practical and educational accompaniment allowing at the same time to realize a diagnosis of the progress of the quality approach, a measure of the impact of the global impregnation within the institution and a comparison between pole. A eight axis dashboard with criteria and a user guide were developed from certification ISO 9001, the EFQM manual and the certification manual version 2 of the Healthcare High Authorities. The criteria are transcribed in an EXCEL grid ready to use. Succeeding in estimating your own quality system means that you demonstrate the maturity of the quality approach. The results of this evaluation confirmed those of the certification. The dashboard is a management structuring tool at the service of the multidisciplinary team. Two considerations emerge from these results: First of all, for the hospital top management, the axes to be improved emerge as a priority to determine and target the next annual action plans. The results also allow to support the auto evaluation for the certification version 2010 planned in January of the same year. It is a pragmatic tool which allows auto evaluation and comparison to estimate the pole performances. It is a strategic

    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

    The Contrast Sensitivity Function (CSF) is a valuable tool which can be used to characterize functional vision and also for the diagnosis and management of patients with different eye diseases. In spite of its usefulness, the CSF is currently hardly ever used in clinical practice. The aim of this study was to validate the use of the system called FVC-100 (Tecnovinc-UNT-CONICET, Argentina), which calculates the CSF, in order to transfer this important tool to ophthalmological clinics. The validation was carried out through the design of a repeatability test and the subsequent analysis of the results. Furthermore, we evaluated the impact of different factors influencing the repeatability of the measurements such as age and previous training. The tests were based on the discrimination of sinusoidal gratings for different spatial frequencies (1, 4 and 12 c/°) in both eyes of 12 people, aged between 20 and 70. The results show that the calculated values of SC of each subject have a high repeatability and are not dependent on age or training. These results allow us to conclude positively regarding the effectiveness of the FVC-100, and to validate its use in clinics for the calculation of the FSC as a standard measure of functional vision quality.

    The purpose of this paper is to find the Target Locator Lines (TLLs) which perform best by contrasting and comparing experiment based on three kinds of TTLs of fighter HMD. 10 university students, male, with an average age of 21-23, corrected visual acuity 1.5, participated in the experiment. In the experiment, head movement data was obtained by TrackIR. The geometric relationship between the coordinates of the real world and coordinates of the visual display was obtained by calculating the distance from viewpoint to midpoint of both eyes and the head movement data. Virtual helmet system simulation experiment environment was created by drawing TLLs of fighter HMD in the flight simulator visual scene. In the experiment, eye tracker was used to record the time and saccade trajectory. The results were evaluated by the duration of the time and saccade trajectory. The results showed that the symbol"locator line with digital vector length indication" cost most time and had the longest length of the saccade trajectory. It is the most ineffective and most unacceptable way. "Locator line with extending head vector length symbol" cost less time and had less length of the saccade trajectory. It is effective and acceptable;"Locator line with reflected vector length symbol" cost the least time and had the least length of the saccade trajectory. It is the most effective and most acceptable way. "Locator line with reflected vector length symbol" performs best. The results will provide reference value for the research of TTLs in future.

    AIM To evaluate the intra-operator repeatability in healthy subjects using the WAM-5500 auto-kerato/refractometer and the iTrace aberrometer, to compare the refractive values and the subjective refraction obtained with both devices and to determine which of these three spherocylindrical corrections allows the subject to achieve the best visual comfort. METHODS Forty-two non-presbyopic healthy eyes of 42 subjects were enrolled in this prospective study. Refractive values were compared, evaluating the repeatability, the relationship between the methods and the best visual comfort obtained. RESULTS Sphere, cylinder and axis results showed good intraclass correlation coefficients (ICC); the highest ICC was obtained using the spherical refraction with the autorefractometer and the aberrometer, achieving levels of 0.999 and 0.998, respectively. The power vector (PV) was calculated for each refraction method, and the results indicated that there were no statistically significant differences between them (P>0.05). Direct comparison of PV measurements using the three methods showed that aberrometer refraction gave the highest values, followed by the subjective values; the autorefractometer gave the lowest values. The subjective method correction was most frequently chosen as the first selection. Equal values were found for the autorefractometer and the aberrometer as the second selection. CONCLUSION The iTrace aberrometer and the WAM-5500 auto-kerato/refractometer showed high levels of repeatability in healthy eyes. Refractive corrections with the aberrometer, the autorefractometer and subjective methods presented similar results, but spherocylindrical subjective correction was the most frequently selected option. These technologies can be used as complements in refractive evaluation, but they should not replace subjective refraction. PMID:26558222

    Revised accreditation standards for dental and dental hygiene education programs have increased emphasis on faculty development that can improve teaching and learning, foster curricular change including use of teaching and learning technologies, and enhance retention and satisfaction of faculty. The American Dental Education Association (ADEA) and Academy for Academic Leadership (AAL) established the Institute for Allied Health Educators (IAHE) in 2007 to address faculty development needs for allied dental and allied health educators. In 2009, it was transitioned to an online program, which resulted in increased enrollment and diversity of participants. After seven years, a comprehensive program evaluation was warranted. The authors developed an online questionnaire based on Kirkpatrick's four-level model of training evaluation; for this study, levels one (satisfaction), two (knowledge and skill acquisition), and three (behavior change) were examined. Of the 400 program participants invited to take part in the study, a 38% response rate was achieved, with the majority indicating full-time faculty status. Nearly all (95-97%) of the respondents agreed or strongly agreed the program contributed to their teaching effectiveness, and 88-96% agreed or strongly agreed it enhanced their knowledge of educational concepts and strategies. In addition, 83% agreed or strongly agreed the program helped them develop new skills and confidence with technology, with 69% agreeing or strongly agreeing that it helped them incorporate technology into their own educational setting. Nearly 90% were highly positive or positive in their overall assessment of the program; 95% indicated they would recommend it to a colleague; and 80% agreed or strongly agreed they had discussed what they learned with faculty colleagues at their home institutions who had not attended the program. Positive findings from this evaluation provide evidence that the IAHE has been able to meet its goals. PMID:25941140

    This paper presents numerous bench tests investigated at Southwest Research Institute which were intended to evaluate the performance of automotive engine and gear oils, and aircraft turbine lubricants. In most cases the tests were designed to simulate certain aspects of the environment seen by the lubricant while performing its function, and lubricant degradation with subsequent deposit formation are the parameters measured. Although in many instances good correlation with specific engine tests were achieved, the final measure of acceptability of a finished lubricant for military applications remains the full engine tests for engine oils; automotive gear tests for gear oils, and full-scale turbine engine tests for the aircraft lubricants. The tests discussed here are excellent screening devices for new experimental lubricant formulations.

    Purpose To examine the relationship of choroidal thickness with axial length (AL) and myopia in young adult eyes in the ethnically diverse Correction of Myopia Evaluation Trial (COMET) cohort. Design Cross-sectional, multi-center, study Methods In addition to measures of myopia by cycloplegic autorefraction and AL by A-scan ultrasonography, participants underwent optical coherence tomography imaging of the choroid (RTVue) in both eyes at their last visit (14 years after baseline). Using digital calipers, two independent readers measured choroidal thickness in the right eye (left eye if poor quality; n=37) at seven locations: fovea and 750, 1500, 2250μm nasal (N) and temporal (T) to the fovea. Results Choroidal thickness measurements were available from 294/346 (85%) of imaged participants (mean age: 24.3±1.4 years; 44.9% male) with mean myopia of -5.3±2.0D and mean AL of 25.5±1.0mm. Overall, choroidal thickness varied by location (p<0.0001) and was thickest at the fovea (273.8±70.9 μm) and thinnest nasally (N2250,191.5±69.3 μm). Multivariable analyses showed significantly thinner choroids in eyes with more myopia and longer AL at all locations except T2250 (p≤0.001) and presence of peri-papillary crescent at all locations except T1500 and T2250 (p≤0.0001). Choroidal thickness varied by ethnicity at N2250 (p<0.0001), with Asians having the thinnest and African Americans the thickest choroids. Conclusion Choroids are thinner in longer, more myopic young adult eyes. The thinning was most prominent nasally and in eyes with a crescent. In the furthest nasal location, ethnicity was associated with choroidal thickness. The findings suggest that choroidal thickness should be evaluated, especially in the nasal regions where myopic degenerations are most commonly seen clinically. PMID:25896460

    Encouraged by recent clinical reports of micturition induced in patients by direct bladder stimulation, we conducted a study of optimum methods of direct bladder stimulation. During surgery six male cats received eight large surface-area woven eye electrodes sutured to the bladder wall serosa, four on the bladder dome and four adjacent to the trigone area. Two additional small surface-area single knot electrodes were sutured in the trigone area. Suprapubic and intraperitoneal tubes were placed for pressure recording and bladder filling. Leg and pelvic floor EMG electrodes were also used for tethered recordings. One to eight weeks after surgery, optimum stimulation methods were evaluated as the animal freely moved about a urodynamic recording cage. Electrodes in the trigone region were more effective than electrodes on the dome and induced bladder contractions and voiding similar to spontaneously induced voiding with bladder filing. Large surface area, woven eye electrodes, composed of multistranded 316LVM stainless steel wire, were more effective than smaller surface area single knot electrodes. High stimulating frequencies (40 Hz) were better than lower frequencies (10 to 20 Hz), and a 1 millisecond pulse duration was optimal. Pulsing with stimulating currents from 10 to 25 mA induced effective bladder contractions with voiding when applied for 3 seconds. However, lower currents using longer stimulation periods were also effective. Bipolar electrodes with both electrodes on the bladder wall were superior to monopolar arrangements with the positive ground electrode along the animal's back. We concluded that in the able-bodied cat model, bladder contractile activity for micturition can be induced with direct bladder stimulation and with little discomfort. An effective stimulation protocol consists of capacitor-coupled monophasic pulses with large surface area bipolar electrodes in the trigone region. Stimulating parameters of 40 Hz, 1 msec., 10 to 25 mA applied for

    This study examined transferability of developed rule sets in an Alpine test site of Germany (Oberammergau) on classifying forest/non-forest at level 1 and forest types (coniferous, deciduous and mixed) at level 2 from RapidEye satellite image. It was evaluated in test sites of three environmental settings; Ethiopia (Munessa), Ecuador (San Francisco) and China (Shangnan) with similar land use/cover types and topography. The same pre-processing steps were applied in each image of all test sites. Object-based image analysis was used to evaluate the rule sets transferability. Comparisons of direct transferability were conducted using accuracies of the classified images. The forest/non-forest classification at level 1 result reveals the direct transferability. However, accuracies decline steeply along with a disturbed nature of the forest resources. The results of forest type classification at level 2 also show the need of further refinement of the already developed rule sets. Adding more rules or adapting to each of the environmental setting is recommended for higher accuracy.

    The aim of this study was to investigate whether S-(-)-10,11-dihydroxyfarnesic acid methyl ester produced by cell subtype Beauveria bassiana CS1029 causes acute toxicity when used for cosmetic purposes by performing an eye irritation test. New Zealand white (NZW) rabbits were treated with a 100 mg/dose of S-(-)-10,11-dihydroxyfarnesic acid methyl ester according to standard procedure guidelines. No significant changes in terms of ocular lesions of the cornea, turbidity of the cornea, swelling of the eyelid or ocular discharge were observed in the methyl ester-treated groups, while sodium dioctyl sulfosuccinate, a positive control, caused severe toxicity. The anatomical and pathological observations indicate that the methyl ester produced by Beauveria bassiana CS1029 did not induce eye irritation in the lenses of the rabbits. The data suggest that the methyl ester evaluated in this study has promising potential as a cosmetic ingredient that does not irritate the eye. PMID:24137288

    Automated retina image analysis has reached a high level of maturity in recent years, and thus the question of how validation is performed in these systems is beginning to grow in importance. One application of retina image analysis is in telemedicine, where an automated system could enable the automated detection of diabetic retinopathy and other eye diseases as a low-cost method for broad-based screening. In this work we discuss our experiences in developing a telemedical network for retina image analysis, including our progression from a manual diagnosis network to a more fully automated one. We pay special attention to how validations of our algorithm steps are performed, both using data from the telemedicine network and other public databases.

    We present a novel experimental technique to determine eye ulcers in animals using a spectral electrical impedance technique. We expect that this technique will be useful in dry eye syndrome. We used a sensor that is basically a platinum (Pt) microelectrode electrically insulated by glass from a cylindrical stainless steel counter-electrode. This sensor was applied to the naked eye of New Zealand rabbits (2.0-3.5 kg in weight). Whereas half of the eyes were normal (control), we applied to the remainder a few drops of 20% (v/v) alcohol to produce an ulcer in the eye. Using a multispectral electrical impedance system we measured ulcerated and control eyes and observed significant difference between normal and pathological samples. We also investigated the effects of different applied pressures and natural degradation of initially normal eyes as a function of time. We believe that this technique could be sufficiently sensitive and repetitive to help diagnose ocular surface diseases such as dry eye syndrome.

    Laboratory research shows that eye-closure during memory retrieval improves both the amount and the factual accuracy of memory reports about witnessed events. Based on these findings, we developed the Eye-Closure Interview, and examined its feasibility (in terms of compliance with the instructions) and effectiveness (in terms of the quantity and quality of reported information) in eyewitness interviews conducted by the South African Police Service. Police interviewers from the Facial Identification Unit were randomly assigned to receive Eye-Closure Interview training or no training. We analyzed 95 interviews with witnesses of serious crimes (including robbery, rape, and murder), some of whom were instructed to close their eyes during salient parts of the interview. Witnesses in the control condition rarely spontaneously closed their eyes, but witnesses in the Eye-Closure Interview condition kept their eyes closed during 97% of their descriptions, suggesting that the Eye-Closure Interview would be easy to implement in a field setting. Although witnesses who closed their eyes did not remember more information overall, the information they provided was considered to be of significantly greater forensic relevance (as reflected in 2 independent blind assessments, 1 by a senior police expert and 1 by a senior researcher). Thus, based on the findings from this field study and from previous laboratory research, we conclude that implementation of the Eye-Closure Interview in witness interviews would help police interviewers to elicit more valuable information from witnesses, which could be relevant to the police investigation and/or in court.

  1. IMAGE-GUIDED EVALUATION AND MONITORING OF TREATMENT RESPONSE IN PATIENTS WITH DRY EYE DISEASE

    PubMed Central

    Hamrah, Pedram

    2014-01-01

    Dry eye disease (DED) is one of the most common ocular disorders worldwide. The pathophysiological mechanisms involved in the development of DED are not well understood and thus treating DED has been a significant challenge for ophthalmologists. Most of the currently available diagnostic tests demonstrate low correlation to patient symptoms and have low reproducibility. Recently, sophisticated in vivo imaging modalities have become available for patient care, namely, in vivo confocal microscopy (IVCM) and optical coherence tomography (OCT). These emerging modalities are powerful and non-invasive, allowing real-time visualization of cellular and anatomical structures of the cornea and ocular surface. Here we discuss how, by providing both qualitative and quantitative assessment, these techniques can be used to demonstrate early subclinical disease, grade layer-by-layer severity, and allow monitoring of disease severity by cellular alterations. Imaging-guided stratification of patients may also be possible in conjunction with clinical examination methods. Visualization of subclinical changes and stratification of patients in vivo, allows objective image-guided evaluation of tailored treatment response based on cellular morphological alterations specific to each patient. This image-guided approach to DED may ultimately improve patient outcomes and allow studying the efficacy of novel therapies in clinical trials. PMID:24696045

  2. Imaging shear stress distribution and evaluating the stress concentration factor of the human eye

    Healthy eyes are vital for a better quality of human life. Historically, for man-made materials, scientists and engineers use stress concentration factors to characterise the effects of structural non-homogeneities on their mechanical strength. However, such information is scarce for the human eye. Here we present the shear stress distribution profiles of a healthy human cornea surface in vivo using photo-stress analysis tomography, which is a non-intrusive and non-X-ray based method. The corneal birefringent retardation measured here is comparable to that of previous studies. Using this, we derive eye stress concentration factors and the directional alignment of major principal stress on the surface of the cornea. Similar to thermometers being used for monitoring the general health in humans, this report provides a foundation to characterise the shear stress carrying capacity of the cornea, and a potential bench mark for validating theoretical modelling of stresses in the human eye in future.

  5. A Fuzzy-Based Fusion Method of Multimodal Sensor-Based Measurements for the Quantitative Evaluation of Eye Fatigue on 3D Displays

    2015-01-01

    With the rapid increase of 3-dimensional (3D) content, considerable research related to the 3D human factor has been undertaken for quantitatively evaluating visual discomfort, including eye fatigue and dizziness, caused by viewing 3D content. Various modalities such as electroencephalograms (EEGs), biomedical signals, and eye responses have been investigated. However, the majority of the previous research has analyzed each modality separately to measure user eye fatigue. This cannot guarantee the credibility of the resulting eye fatigue evaluations. Therefore, we propose a new method for quantitatively evaluating eye fatigue related to 3D content by combining multimodal measurements. This research is novel for the following four reasons: first, for the evaluation of eye fatigue with high credibility on 3D displays, a fuzzy-based fusion method (FBFM) is proposed based on the multimodalities of EEG signals, eye blinking rate (BR), facial temperature (FT), and subjective evaluation (SE); second, to measure a more accurate variation of eye fatigue (before and after watching a 3D display), we obtain the quality scores of EEG signals, eye BR, FT and SE; third, for combining the values of the four modalities we obtain the optimal weights of the EEG signals BR, FT and SE using a fuzzy system based on quality scores; fourth, the quantitative level of the variation of eye fatigue is finally obtained using the weighted sum of the values measured by the four modalities. Experimental results confirm that the effectiveness of the proposed FBFM is greater than other conventional multimodal measurements. Moreover, the credibility of the variations of the eye fatigue using the FBFM before and after watching the 3D display is proven using a t-test and descriptive statistical analysis using effect size.

    The present paper summarizes the results of our studies on dermal and eye irritation and skin sensitization due to carbon nanotubes (CNTs), whose potential applications and uses are wide and varied, including CNT-enhanced plastics, electromagnetic interference/radio-frequency (EMI/RFI) shielding, antistatic material, flexible fibers and advanced polymers, medical and health applications, and scanning probe microscopy. Skin and eyes have the highest risk of exposure to nanomaterials, because deposition of nanomaterials to the surficial organs has the potential to be a major route of exposure during the manufacturing, use, and disposal of nanomaterials. Two products composed of single-walled carbon nanotubes (SWCNTs) and two products composed of multi-walled carbon nanotubes (MWCNTs) were tested regarding acute dermal and acute eye irritation using rabbits, and skin sensitization using guinea pigs. The concentrations of the CNTs in the substances were the maximum allowable for administration. The two products of SWCNTs and one of the products of MWCNTs were not irritants to the skin or eyes. The other product of MWCNTs caused very slight erythema at 24h, but not at 72h, after patch removal in the dermal irritation experiments and conjunctival redness and blood vessel hyperemia at 1h, but not at 24h, in eye irritation experiments. These findings showed that one product of MWCNTs was a very weak acute irritant to the skin and eyes. No products of SWCNTs and MWCNTs exhibited skin-sensitization effects. Our knowledge of the toxicological effects of CNTs is still limited. Further information is needed to clarify the potential for irritation and sensitization given the complex nature of CNTs.

    2013-01-01

    Background The polyherbal eye drop (Itone™) is a mixture of aqueous distillates of nineteen traditionally used ingredients that sum up to impart potency to the formulation and make it a useful adjunct in various ocular pathologies. However, as there have been no controlled experimental studies accounting to the above claim, therefore, the present study was designed to evaluate the polyherbal formulation (PHF) for antiangiogenic, anti-inflammatory, anticataract, antioxidant and cytotoxicity in addition to the evaluation of intraocular penetration of PHF in rabbit eyes using LC-MS/MS. Materials and methods Antiangiogenic activity of the PHF was evaluated using in ovo chick chorio-allantoic membrane (CAM) assay and in vivo cautery induced corneal neovascularization assay in rats. Anticataract potential was evaluated using steroid induced cataract in developing chick embryos, sodium selenite induced cataract in rat pups and galactose induced cataract in rats. The antioxidant activity was evaluated using di-phenyl picryl hydrazyl (DPPH) radical scavenging assay. Anti-inflammatory activity was evaluated in vitro using inhibition of LTB4 formation in human WBCs and in vivo using carrageenan induced paw edema assay in rats. The cytotoxicity was evaluated against HeLa cancer cell lines using (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Furthermore evaluation of the intraocular penetration of the PHF was carried out in rabbit eyes via aqueous humor paracentesis and further analysis using LC-MS/MS. Results PHF significantly inhibited VEGF induced proliferation of new blood vessels in CAM assay and inhibited the cautery induced corneal neovascularization in rats. Additionally, PHF showed noticeable delay in the progression of cataract in the selenite and galactose induced cataract models whereby the PHF treated lenses were graded for stages II and III respectively. However, the PHF did not show any anticataract activity in the hydrocortisone

    Purpose We investigated the correlations between optical quality parameters obtained from the double-pass system and ocular aberrations obtained from the ray-tracing aberrometer in multifocal intraocular lens (IOL) implanted eyes. Materials and Methods Twenty eyes from 20 patients were enrolled in this study. Modulation transfer function cutoff frequency, The Strehl ratio, objective scatter index, and objective pseudo-accommodation obtained from the double-pass system were compared with root mean square (RMS) total aberration, RMS higher-order aberration, and spherical aberration obtained from the ray-tracing aberrometer. Additionally, parameters of the double-pass system and ray-tracing aberrometer were compared with manifested refraction values and subjective visual acuity, respectively. Results There was no statistically significant correlation between optical quality parameters obtained from the double-pass system and ocular aberrations, except between the Strehl ratio and RMS total aberration (r=-0.566, p=0.018). No significant correlations were found between the parameters of both devices, and manifested refraction values or subjective visual acuity. Conclusion Optical quality parameters, especially the Strehl ratio, in multifocal IOL implanted eyes were affected by RMS total aberration. Further studies based on accurate measurements of ocular aberrations and additional optical quality parameters are needed to delineate relationships between optical quality parameters and ocular aberrations in multifocal IOL implanted eyes.

  4. Impression Evaluation and Eye Movement Related to The Characteristic Expression as Elements in Abstract Paintings: Mondrian, Malewitsch and Rothko

    NASA Astrophysics Data System (ADS)

    Yoshioka, Kiyomi

    This paper has the purpose to inspect differences regarding impression evaluation and eye movement by comparing characteristic expression as elements in abstract paintings. Malewitsch's paintings which emphasize oblique lines and inclined rectangles elicited impression evaluations such as “hard”, “irritable”, “dynamic” and “exciting”. Mondrian's paintings which emphasize vertical and horizontal line elicited impression evaluations such as “cheerful” and “light”. Rothko's paintings which are obscure outlines elicited impression evaluations such as “mild”, “comfortable”, “relaxing”, “static” and “tedious”. Paintings that have clear vertical and horizontal lines elicit a trend toward higher mean line-of-sight velocity. Paintings that have many distinctive expression elements elicit large frequency of long gaze point. This study indicates that vertical lines, horizontal lines, oblique lines, obscure outlines, and other expression elements in abstract paintings are influencing factors for impression evaluation and eye movement. This suggests that mutual interactions of components that constitute paintings cannot be disregarded. This study is inspection of common impression and perception caused by appreciation of paintings.

    When Cuba was hit by a neuropathy epidemic two decades ago, Dr Rosaralis Santiesteban was one of the Cuban health professionals who played a key role in its management, as reflected in a recent issue of Seminars in Ophthalmology. She was well prepared for her part: trained in medicine at the University of Havana before completing a residency in ophthalmology and eventually a doctorate in medical sciences, she has received multiple honors for her research, publishing and teaching. In 2007, she was named Distinguished Researcher by the Cuban Ministry of Science, Technology and the Environment. She has headed the Department of Neuro-ophthalmology at Cuba's Neurology and Neurosurgery Institute since 1977. Now called Cuban Epidemic Neuropathy, the 1990s epidemic that affected over 50,000 Cubans is the largest and best-documented of its kind in history. As researchers pressed to unravel the mystery of its etiology to hasten the epidemic's end, Dr Santiesteban recognized that similar outbreaks had occurred during Cuba's wars of independence in the late 1800s--described in her book, Epidemias y Endemias de neuropatía en Cuba. In the proverbial eye of the storm during the 1990s epidemic, she shares her reflections below on the context, causes, evolution and lessons learned from the challenge that put Cuba's health system to the test.

    While the major technological goal of laser eye protection (LEP) is to attenuate any laser radiation that passes through it, consideration of the physical format in which it is realized must not be overlooked. The best protective material can be rendered essentially useless if it does not cover the appropriate field of regard for the wearer. To map the visual field of regard (FOR) coverage provided by LEP devices, the field of view evaluation apparatus (FOVEA) was used. The FOVEA is a one-meter radius arc perimeter containing computer-controlled light emitting diodes at one-degree intervals. Three different mapppings of the visual field can be obtained with this facility: (a) the monocular baseline FOR; (b) the accessibility the LEP demonstrates against the direct threat (i.e., a laser source entering the eye beyond frame edge); and (c) the accessibility to indirect hazard (i.e., laser energy reflected from the lens backside entering the eye). Comparison of the direct and indirect fields of regard demonstrates the wide coverage variation generated by alternate frame styles and differing head shapes. These results need to be interpreted with respect to FOVEA limitations. First, the full FOR is mapped without regard for the relative importance of the periphery versus the fovea. Second, the coverage from a particular frame style must be measured and specified with an appropriate range of anthropometric face forms to ensure coverage consistency.

    2007-01-01

    The influence of vitreoretinal proliferative changes on retinal electrogenesis and glioneuronal relationships was studied in 41 patients with penetrating shell injury to the eye. The early data of studies indicated that there is a reduction in the hanz-feldt amplitude on an electroretinogram (ERG). According to the data of optic coherent tomography (OCT), this corresponds to an exudative reactive response and to the development of vitreoretinal tractional changes in the retina in the central zone and at the site of a foreign body. Retinal electrogenetic changes were most pronounced at months 1 to 6 of a follow-up. The integral glial index was decreased and the central index of Müller's cells was drastically increased in the injured eyes. In this period, there was a reduction in an exudative response to injury and an increase in vitreoretinal proliferative changes, as evidenced by OCT. In late posttraumatic period, the injured eyes were characterized by a slow increase in the amplitude of biopotentials that did not achieve the lower normal range just 1 year or more after injuring. Late posttraumatic inhibition is likely to be caused by vitreoretinal complications of mainly dystrophic nature in the central retinal zone and at the site of fragment bedding or removed foreign body.

    Background The aim of this study was to assess the value of ultrasonic biomicroscopy in reporting decreases in intraocular pressure resulting from changes in anterior chamber depth and angle after phacoemulsification and intracapsular lens implantation in patients with cataract. Methods This prospective interventional case series included 50 eyes of 50 consecutive subjects operated at the same center. Patients with eye disease affecting visual acuity, a history of eye surgery, corneal surface irregularities, a pupil diameter < 5 mm after preoperative dilation, aged younger than 35 years, posterior capsule perforation, iris dialysis during surgery, intensive postoperative corneal edema, and inability to attend adequate follow-up were excluded. Intraocular pressure, anterior chamber depth and angle, and corneal thickness were measured before and one month after surgery. Results The mean preoperative intraocular pressure was 14 mmHg and postoperatively was 11 mmHg. Mean anterior chamber depth preoperatively was 2.8 mm and increased to 3.7 mm postoperatively. The mean anterior chamber angle was measured as 27° preoperatively and as 42° postoperatively. Conclusion After phacoemulsification and intracapsular lens implantation, ultrasonic biomicroscopy showed that the iris diaphragm had shifted backwards, widening the angle of the anterior chamber and decreasing intraocular pressure.

    Objective To estimate the cost-effectiveness of visual acuity screening performed in primary care settings and of dilated eye evaluations performed by an eye care professional among new Medicare enrollees with no diagnosed eye disorders. Medicare currently reimburses visual acuity screening for new enrollees during their initial preventive primary care health check, but dilated eye evaluations may be a more cost-effective policy. Design Monte Carlo cost-effectiveness simulation model with a total of 50 000 simulated patients with demographic characteristics matched to persons 65 years of age in the US population. Results Compared with no screening policy, dilated eye evaluations increased quality-adjusted life-years (QALYs) by 0.008 (95% credible interval [CrI], 0.005–0.011) and increased costs by $94 (95% CrI, −$35 to $222). A visual acuity screening increased QALYs in less than 95% of the simulations (0.001 [95% CrI, −0.002 to 0.004) and increased total costs by $32 (95% CrI, −$97 to $159) per person. The incremental cost-effectiveness ratio of a visual acuity screening and an eye examination compared with no screening were $29 000 and $12 000 per QALY gained, respectively. At a willingness-to-pay value of $15 000 or more per QALY gained, a dilated eye evaluation was the policy option most likely to be cost-effective. Conclusions The currently recommended visual acuity screening showed limited efficacy and cost-effectiveness compared with no screening. In contrast, a new policy of reimbursement for Welcome to Medicare dilated eye evaluations was highly cost-effective. PMID:22232367

    Mechanical eye models are used to validate ex vivo the optical quality of intraocular lenses (IOLs). The quality measurement and test instructions for IOLs are defined in the ISO 11979-2. However, it was mentioned in literature that these test instructions could lead to inaccurate measurements in case of some modern IOL designs. Reproducibility of alignment and measurement processes are presented, performed with a semiautomatic mechanical ex vivo eye model based on optical properties published by Liou and Brennan in the scale 1:1. The cornea, the iris aperture and the IOL itself are separately changeable within the eye model. The adjustment of the IOL can be manipulated by automatic decentration and tilt of the IOL in reference to the optical axis of the whole system, which is defined by the connection line of the central point of the artificial cornea and the iris aperture. With the presented measurement setup two quality criteria are measurable: the modulation transfer function (MTF) and the Strehl ratio. First the reproducibility of the alignment process for definition of initial conditions of the lateral position and tilt in reference to the optical axis of the system is investigated. Furthermore, different IOL holders are tested related to the stable holding of the IOL. The measurement is performed by a before-after comparison of the lens position using a typical decentration and tilt tolerance analysis path. Modulation transfer function MTF and Strehl ratio S before and after this tolerance analysis are compared and requirements for lens holder construction are deduced from the presented results.

    To identify components of a provisional clinical response index for thyroid eye disease (CRI-TED) using a modified Delphi technique. The International Thyroid Eye Disease Society (ITEDS) conducted a structured, 3-round Delphi exercise establishing consensus for a core set of measures for clinical trials in TED. The steering committee discussed the results in a face-to-face meeting (nominal group technique) and evaluated each criterion with respect to its feasibility, reliability, redundancy, and validity. Redundant measures were consolidated or excluded. Criteria were parsed into 11 domains for the Delphi surveys. Eighty four respondents participated in the Delphi-1 survey, providing 220 unique items. Ninety- two members (100% of the respondents from Delphi 1 plus eight new participants) responded in Delphi-2 and rated the same 220 items. Sixty-four members (76% of participants) rated 153 criteria in Delphi-3 (67 criteria were excluded due to redundancy). Criteria with a mean greater than 6 (1 least appropriate to 9 most appropriate) were further evaluated by the nominal group technique and provisional core measures were chosen. Using a Delphi exercise, we developed provisional core measures for assessing disease activity and severity in clinical trials of therapies for TED. These measures will be iteratively refined for use in multicenter clinical trials. PMID:19752424

    Continuous, high quality profiles of water vapor, free of systematic bias, and of moderate temporal and spatial resolution are fundamental to the success of the ARM CART program. In addition, these should be acquired over long periods at low operational and maintenance cost. The development and verification of realistic climate model parameterizations for clouds and net radiation balance, and the correction of other CART site sensor observations for interferences due to the presence of water vapor are critically dependent on water vapor profile measurements. To date, application of profiles have been limited by vertical resolution and uniqueness and high operating cost, or diminished daytime performance, lack of eye-safety, and high maintenance cost. Recent developments in infrared laser and detector technology make possible compact IR differential absorption lidar (DIAL) systems at eye-safe wavelengths. In the studies reported here, we develop DIAL system performance models and examine the potential of solving some of the shortcomings of previous methods using parameters representative of current technologies. These simulations are also applied to determine the strengths and weaknesses unique to the DIAL method for this application.

    Purpose To examine the effect of misalignment (decentration and tilt) of intraocular lenses (IOLs) on retinal image quality using a water-immersed model eye with corneal spherical aberration adjusted to the values found in normal human eyes (spherical aberration 0.25 μm; pupil diameter 6 mm). Methods Three types of IOL holders were prepared. The first was without decentration or tilt, the second had a decentration of 0.5 mm, and the third had a tilt of 5.0°. One spherical IOL and three aspherical IOLs, each with a power of +20 D, were set in the holders and their optical properties (wave front aberration, defocused modulation transfer function, defocused point spread function, and Landolt ring simulations) were compared. Results Coma aberrations generated by misaligned IOLs were related to the spherical aberration corrective power of the IOLs. Landolt ring simulations show that the depth of focus increased as spherical aberration increased and that the retinal image quality was degraded by increases in coma aberration. Conclusion Coma aberration was generated by IOLs with a large degree of spherical aberration correction, leading to reduced retinal image quality when the IOL was misaligned. This suggests that, in a clinical setting, the quality of vision might be improved by reducing the degree of coma aberration using IOLs that retain, or minimally correct, spherical aberration.

    Exposure to intense radiation sources in a dental clinic necessitates the use of eye protective filters to avoid blue-light photochemical retinal hazard. We have investigated the filtering quality and assessed whether the filters protect sufficiently against retinal hazards throughout the workday. Visible light transmittance of 18 protective filters was measured. These products consisted of spectacles, stationary lamp shields, and a hand-held shield intended for use in dental clinics. Nine of the 18 tested filters had adequate filtering capacity according to today's lamp technology and exposure limit values. These filters transmitted less than 0.1% of the radiation at any wavelength between 400 nm and 525 nm. Seven of the nine filters showed transmission values below the detection limit (approximately 10(-3)%) in the wavelength band between 400 nm and 500 nm. Filters of inferior quality may prove inadequate if the use and radiation intensity of the lamps further increase. Lack of protection may also occur if a filter is used to protect against emission from a lamp with properties other than the lamp for which the filter has been intended. It is of major importance that the spectacles/shields accommodate the emission from the lamp source. The suppliers of dental radiation sources should be responsible for information on the need for and proper use of eye protectors. In addition, the filters should be marked according to testing procedures appropriate for the specific use. PMID:17474033

    Purpose. To assess the conjunctival functionality in a rabbit dry eye (DE) model. Methods. Nictitating membrane, lacrimal and Harderian glands were surgically excised from male New Zealand white rabbits using minimally invasive surgery. Fluorescein/rose Bengal staining of ocular surface (OS) and Schirmer test were done before (BE) and after excision (AE). The expression of interleukin- (IL-) 1β, tumor necrosis factor- (TNF-) α, and MUC5AC proteins were estimated by immunoblotting from conjunctival impression cytology specimens. MUC5AC mRNA was quantified as well. The effect of epithelial sodium channel (ENaC) blockers on tear production and potential differences (PD) of OS were assessed under anesthesia in rabbits with and without surgery. Results. Increase in corneal and conjunctival staining was observed 1 month AE compared to BE. Schirmer tests failed to show decrease in tear production. Elevated IL-1β, and TNF-α, 1 month AE indicated inflammation. MUC5AC expression was elevated 1 month AE. ENaC blockers did not improve tear production in rabbit eyes AE but characteristic changes in PD were observed in rabbits with surgery. Conclusions. DE biomarkers are important tools for OS assessment and MUC5AC expression is elevated in rabbit DE. PD measurement revealed significant electrophysiological changes in rabbits with surgery.

    Neck dissection is a surgical intervention at which cervical lymph node metastases are removed. Accurate surgical planning is of high importance because wrong judgment of the situation causes severe harm for the patient. Diagnostic perception of radiological images by a surgeon is an acquired skill that can be enhanced by training and experience. To improve accuracy in detecting pathological lymph nodes by newcomers and less experienced professionals, it is essential to understand how surgical experts solve relevant visual and recognition tasks. By using eye tracking and especially the newly-developed attention landscapes visualizations, it could be determined whether visualization options, for example 3D models instead of CT data, help in increasing accuracy and speed of neck dissection planning. Thirteen ORL surgeons with different levels of expertise participated in this study. They inspected different visualizations of 3D models and original CT datasets of patients. Among others, we used scanpath analysis and attention landscapes to interpret the inspection strategies. It was possible to distinguish different patterns of visual exploratory activity. The experienced surgeons exhibited a higher concentration of attention on the limited number of areas of interest and demonstrated less saccadic eye movements indicating a better orientation.

    The last recommendations of the International Commission on Radiological Protection for eye lens dose suggest an important reduction on the radiation limits associated with early and late tissue reactions. The aim of this work is to quantify and optimize the eye lens dose associated to nurse staff during positron emission tomography (PET) procedures. PET is one of the most important diagnostic methods of oncological and neurological cancer disease involving an important number of workers exposed to the high energy isotope F-18. We characterize the relevant stages as preparation and administration of monodose syringes in terms of occupational dose. A direct reading silicon dosimeter was used to measure the lens dose to staff. The highest dose of radiation was observed during preparation of the fluorodesoxyglucose (FDG) syringes. By optimizing a suitable vials' distribution of FDG we find an important reduction in occupational doses. Extrapolation of our data to other clinical scenarios indicates that, depending on the work load and/or syringes activity, safety limits of the dose might be exceeded. PMID:27182832

    Purpose: A method is introduced to examine the influence of implant duration T, radionuclide, and radiobiological parameters on the biologically effective dose (BED) throughout the entire volume of regions of interest for episcleral brachytherapy using available radionuclides. This method is employed to evaluate a particular eye plaque brachytherapy implant in a radiobiological context. Methods: A reference eye geometry and 16 mm COMS eye plaque loaded with {sup 103}Pd, {sup 125}I, or {sup 131}Cs sources were examined with dose distributions accounting for plaque heterogeneities. For a standardized 7 day implant, doses to 90% of the tumor volume ( {sub TUMOR}D{sub 90}) and 10% of the organ at risk volumes ( {sub OAR}D{sub 10}) were calculated. The BED equation from Dale and Jones and published {alpha}/{beta} and {mu} parameters were incorporated with dose volume histograms (DVHs) for various T values such as T = 7 days (i.e., {sub TUMOR} {sup 7}BED{sub 10} and {sub OAR} {sup 7}BED{sub 10}). By calculating BED throughout the volumes, biologically effective dose volume histograms (BEDVHs) were developed for tumor and OARs. Influence of T, radionuclide choice, and radiobiological parameters on {sub TUMOR}BEDVH and {sub OAR}BEDVH were examined. The nominal dose was scaled for shorter implants to achieve biological equivalence. Results: {sub TUMOR}D{sub 90} values were 102, 112, and 110 Gy for {sup 103}Pd, {sup 125}I, and {sup 131}Cs, respectively. Corresponding {sub TUMOR} {sup 7}BED{sub 10} values were 124, 140, and 138 Gy, respectively. As T decreased from 7 to 0.01 days, the isobiologically effective prescription dose decreased by a factor of three. As expected, {sub TUMOR} {sup 7}BEDVH did not significantly change as a function of radionuclide half-life but varied by 10% due to radionuclide dose distribution. Variations in reported radiobiological parameters caused {sub TUMOR} {sup 7}BED{sub 10} to deviate by up to 46%. Over the range of {sub OAR

    Purpose To evaluate the clinical safety and comfort of a new benzalkonium chloride-free Visine® lubricant eye drop formulation (Hydroblend™ and GentlePur™) in healthy and dry eye subjects. Methods This was a single-site, open-label clinical study comprised of 22 healthy and 22 dry eye subjects. Subjects were instructed to instill 1–2 drops of the test product four times a day for 2 weeks and were examined at visit 1 (day 0), visit 2 (day 7), and visit 3 (day 14). Assessments at each visit included postdosing product usage comfort scores, predosing fluorescein corneal staining score, predosing visual acuity, and pre- and postdosing ocular structure change using slit-lamp biomicroscopy. Adverse events were monitored throughout the course of the study. Results Throughout the 14 days of the trial period, subjects from both healthy and dry eye groups rated the eye drops as “very comfortable”. For dry eye group, the mean product usage comfort scores for the first 3 minutes postdosing ranged from 8.5 to 8.8 at visit 1 and 9.2 to 9.6 at visit 3 on a 0–10 point scale, with 0 being very uncomfortable and 10 being very comfortable. The mean corneal staining scores over five corneal regions changed from 0.65 at visit 1 to 0.39 at visit 3 for dry eye group. The individual region corneal staining scores were also decreased from visits 1 to 3 for dry eye group. All subjects maintained pretreatment means visual acuity at visits 2 and 3. Biomicroscopic examination indicated no structural changes at all visits. There were no significant adverse events reported during the course of the study. Conclusion The study confirms that GentlePur™ is an appropriate choice as a preservative for ocular application. The new formulation was safe and comfortable when used four times a day in healthy and dry eye subjects. PMID:26929596

    2011-01-01

    This research work is an explorative study to measure efficiency, effectiveness and user satisfaction of a prototype called Infobiotika aiming to support antibiotic use in intensive care. The evaluation was performed by combining traditional usability testing with eye-tracking technology. The test was conducted with eight intensive care physicians whereof four specialists and four residents. During three test phases participants were asked to perform three types of tasks, namely navigational, clinical and tasks to measure the learning effect after 3-5 minutes free exploring time. A post-test questionnaire was used to explore user satisfaction. Based on the results and overall observations, Infobiotika seems to be effective and efficient in terms of supporting navigation and also a learnable product for intensive care physicians fulfilling their need to get an accurate overview of a patient status quickly. Applying eye-tracking technology during usability testing has shown to be a valuable complement to traditional methods that revealed many unexpected issues in terms of navigation and contributed a supplementary understanding about design problems and user performance.

    Introduction: We hypothesized that inappropriate attention during the period of abstinence in individuals with substance use disorder can result in an inadequate perception of emotion and unsuitable reaction to emotional scenes. The main aim of this research was to evaluate the attentional bias towards emotional images in former substance abusers and compare it to healthy adults. Methods: Paired images of general scenes consisting of pleasant, unpleasant, and neutral images were presented to subjects for 3 s while their attentional bias and eye movements were measured by eye tracking. The participants were 72 male adults consisting of 23 healthy control, 24 morphine former abusers, and 25 methamphetamine former abusers. The former abusers were recruited from a private addiction quitting center and addiction rehabilitation campus. The healthy individuals were selected from general population. Number and duration of first fixation, duration of first gaze, and sustained attention towards emotional scenes were measured as the main variables and the data were analyzed using the repeated measures ANOVA. Results: A significant difference was observed between former morphine abusers and healthy control in terms of number and duration of first fixations and first gaze duration towards pleasant images. Discussion: Individuals with morphine use disorder have more problems with attending to emotional images compared to methamphetamine abusers and healthy people. PMID:26649160

    Background: Patient safety is one of the major issues concerning the medical community and the World Health Organization (WHO) in most countries. This study aimed to evaluate the patient safety status in an Eye Hospital in Tehran, using the WHO model for Patient Safety Friendly Hospital Initiatives (PSFHI) in 2012. Methods: This Cross-Sectional study was done in an Eye Hospital in Tehran. Measurement tool was a checklist related to the PSFHI, including 140 standards in three groups of critical, core and developmental. It was covering five domains of: a) Leadership and management, b) Patient and public involvement, c) Safe evidence-based clinical practices, d) Safe environment, and e) Lifelong learning. Results: Compliance with critical, core and developmental standards were 77.78%, 75.29%, and 21.42% respectively. The Rates of Meeting Standards in the leadership and management, patient and public involvement, safe evidence-based clinical practices, secure environment and for lifelong learning were 66.89%, 42.85%, 75.68%, 73.68%, and 63.63% respectively. Conclusions: The PSFHI standards play important role in improving patient safety using leadership, safety practices and creating good working conditions and environment for the staff. So focus on these standards is essential in improving the patient safety in hospitals in Iran. PMID:26120394

    In two recent studies of Spanish individuals, gender was suggested as a factor that contributes to human eye colour variation. However, gender did not improve the predictive accuracy on blue, intermediate and brown eye colours when gender was included in the IrisPlex model. In this study, we investigate the role of gender as a factor that contributes to eye colour variation and suggest that the gender effect on eye colour is population specific. A total of 230 Italian individuals were typed for the six IrisPlex SNPs (rs12913832, rs1800407, rs12896399, rs1393350, rs16891982 and rs12203592). A quantitative eye colour score (Pixel Index of the Eye: PIE-score) was calculated based on digital eye images using the custom made DIAT software. The results were compared with those of Danish and Swedish population samples. As expected, we found HERC2 rs12913832 as the main predictor of human eye colour independently of ancestry. Furthermore, we found gender to be significantly associated with quantitative eye colour measurements in the Italian population sample. We found that the association was statistically significant only among Italian individuals typed as heterozygote GA for HERC2 rs12913832. Interestingly, we did not observe the same association in the Danish and Swedish population. This indicated that the gender effect on eye colour is population specific. We estimated the effect of gender on quantitative eye colour in the Italian population sample to be 4.9%. Among gender and the IrisPlex SNPs, gender ranked as the second most important predictor of human eye colour variation in Italians after HERC2 rs12913832. We, furthermore, tested the five lower ranked IrisPlex predictors, and evaluated all possible 3(6) (729) genotype combinations of the IrisPlex assay and their corresponding predictive values using the IrisPlex prediction model [4]. The results suggested that maximum three (rs12913832, rs1800407, rs16891982) of the six IrisPlex SNPs are useful in practical
