    Millions of people are affected by visual impairment and blindness globally, and the prevalence of vision loss is likely to increase as we are living longer. However, many ocular diseases remain poorly controlled due to lack of proper understanding of the pathogenesis and the corresponding lack of effective therapies. Consequently, there is a major need for animal models that closely mirror the human eye pathology and at the same time allow higher-throughput drug screening approaches. In this context, zebrafish as an animal model organism not only address these needs but can in many respects reflect the human situation better than the current rodent models. Over the past decade, zebrafish have become an established model to study a variety of human diseases and are more recently becoming a valuable tool for the study of human ophthalmological disorders. Many human ocular diseases such as cataract, glaucoma, diabetic retinopathy, and age-related macular degeneration have already been modelled in zebrafish. In addition, zebrafish have become an attractive model for pre-clinical drug toxicity testing and are now increasingly used by scientists worldwide for the discovery of novel treatment approaches. This review presents the advantages and uses of zebrafish for ophthalmological research. PMID:24503724

  7. Global change research highlights

    Wood - the fuel source of the past - is expected to be a fuel source of the future. Fast growing trees are being cloned and nurtured for conversion to biofuels to replace or supplement gasoline for transportation. The future may also bring higher temperatures and drought if global climate changes as predicted. So, it seems practical to raise fastgrowing trees that not only provide fuel by capturing carbon from the atmosphere (helping to deter climate change) but also flourish under dry conditions. A recent ORNL finding has bearing on this goal. Hybrid willow trees have been cloned because they grow fast and serve as good fuel sources. However, there are important gender differences. Male willow clones are generally more tolerant of drought than female willows. Also, male willows cause no weed problems because they do not disperse seeds. In addition research work has looked at the impact of enhanced carbon dioxide environments on the growth of trees and the potential sequestering of carbon dioxide into the trees or soils. Scientists have found that ground-level ozone in the environment can reduce the growth of the loblolly pine, a forest tree species of great economic importance in the Southeast. It is predicted that global warming could lead to changes in regional precipitation, even periods of drought. How would climate change affect the growth of forest trees? This is a question ORNL has been attempting to answer. Geologic records have been studied by means of isotope ratio techniques to study reasons for vegetation changes in the past. The question is what was the reason for these changes.

  10. The research and development of the adaptive optics in ophthalmology

    NASA Astrophysics Data System (ADS)

    Wu, Chuhan; Zhang, Xiaofang; Chen, Weilin

    2015-08-01

    Recently the combination of adaptive optics and ophthalmology has made great progress and become highly effective. The retina disease is diagnosed by retina imaging technique based on scanning optical system, so the scanning of eye requires optical system characterized by great ability of anti-moving and optical aberration correction. The adaptive optics possesses high level of adaptability and is available for real time imaging, which meets the requirement of medical retina detection with accurate images. Now the Scanning Laser Ophthalmoscope and the Optical Coherence Tomography are widely used, which are the core techniques in the area of medical retina detection. Based on the above techniques, in China, a few adaptive optics systems used for eye medical scanning have been designed by some researchers from The Institute of Optics And Electronics of CAS(The Chinese Academy of Sciences); some foreign research institutions have adopted other methods to eliminate the interference of eye moving and optical aberration; there are many relevant patents at home and abroad. In this paper, the principles and relevant technique details of the Scanning Laser Ophthalmoscope and the Optical Coherence Tomography are described. And the recent development and progress of adaptive optics in the field of eye retina imaging are analyzed and summarized.

    Porter L.F., Black G.C.M. Personalized ophthalmology. Clin Genet 2014: 86: 1–11. © 2014 The Authors. Clinical Genetics published by John Wiley & Sons A/S. Published by John Wiley & Sons Ltd., 2014 Ophthalmology has been an early adopter of personalized medicine. Drawing on genomic advances to improve molecular diagnosis, such as next-generation sequencing, and basic and translational research to develop novel therapies, application of genetic technologies in ophthalmology now heralds development of gene replacement therapies for some inherited monogenic eye diseases. It also promises to alter prediction, diagnosis and management of the complex disease age-related macular degeneration. Personalized ophthalmology is underpinned by an understanding of the molecular basis of eye disease. Two important areas of focus are required for adoption of personalized approaches: disease stratification and individualization. Disease stratification relies on phenotypic and genetic assessment leading to molecular diagnosis; individualization encompasses all aspects of patient management from optimized genetic counseling and conventional therapies to trials of novel DNA-based therapies. This review discusses the clinical implications of these twin strategies. Advantages and implications of genetic testing for patients with inherited eye diseases, choice of molecular diagnostic modality, drivers for adoption of personalized ophthalmology, service planning implications, ethical considerations and future challenges are considered. Indeed, whilst many difficulties remain, personalized ophthalmology truly has the potential to revolutionize the specialty. PMID:24665880

  19. [Development of genetic research in ophthalmology with special reference to Switzerland].

    PubMed

    Klein, D

    1990-05-01

    The relationship between ophthalmology and genetics has always been a very active one, and existed even before Mendel's laws of inheritance were known. The pedigree method in particular yielded satisfactory results even to the first researchers. Later, Helmholtz's invention of the ophthalmoscope (in 1851) and the rediscovery of Mendel's laws of heredity (in 1900) made major contributions to the progress of human genetics in ophthalmology. Credit is due to J. F. Horner of Zurich (1831-1886) for having first established the X-chromosomal inheritance of colorblindness. Subsequently, the development of genetic research was advanced in particular by Alfred Vogt, Professor of Ophthalmology in Zurich (1879-1943) and Adolf Franceschetti in Geneva (1896-1968) and their co-workers. We are indebted to Vogt for the first description of albinismus solum bulbi. Credit is also due to him for having made early diagnosis of myotonic dystrophy (Steinert) possible, a major discovery for genetic counseling. He was the first to detect, by slit-lamp examination, characteristic lens changes in the form of whitish, red, and green opacities in the anterior and posterior subcapsular regions. Franceschetti's achievements include the description of several clinical syndromes, of which mandibulofacial dysostosis has become well known. Among the hereditary retinal dystrophies, he described fundus flavimaculatus (yellowish lesions disseminated in the deeper layers of the posterior pole) as a new entity, attributed to degeneration of the pigment epithelium. In addition to more than 500 articles, he was also co-author, with J. François and J. Babel, of a monumental handbook in two volumes titled Hérédodégénérescences choriorétiniennes (of which an English translation appeared in 1974).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2195224

    In ophthalmology, various modalities and tests are utilized to obtain vital information on the eye's structure and function. For example, optical coherence tomography (OCT) is utilized to diagnose, screen, and aid treatment of eye diseases like macular degeneration or glaucoma. Such data are complemented by photographic retinal fundus images and functional tests on the visual field. DICOM isn't widely used yet, though, and frequently images are encoded in proprietary formats. The eXtensible Neuroimaging Archive Tool (XNAT) is an open-source NIH-funded framework for research PACS and is in use at the University of Iowa for neurological research applications. Its use for ophthalmology was hence desirable but posed new challenges due to data types thus far not considered and the lack of standardized formats. We developed custom tools for data types not natively recognized by XNAT itself using XNAT's low-level REST API. Vendor-provided tools can be included as necessary to convert proprietary data sets into valid DICOM. Clients can access the data in a standardized format while still retaining the original format if needed by specific analysis tools. With respective project-specific permissions, results like segmentations or quantitative evaluations can be stored as additional resources to previously uploaded datasets. Applications can use our abstract-level Python or C/C++ API to communicate with the XNAT instance. This paper describes concepts and details of the designed upload script templates, which can be customized to the needs of specific projects, and the novel client-side communication API which allows integration into new or existing research applications.

    2016-02-01

    Each year, millions of metric tons of the plastic produced for food packaging, personal care products, fishing gear, and other human activities end up in lakes, rivers, and the ocean. The breakdown of these primary plastics in the environment results in microplastics, small fragments of plastic typically less than 1-5 mm in size. These synthetic particles have been detected in all of the world's oceans and also in many freshwater systems, accumulating in sediment, on shorelines, suspended in surface waters, and being ingested by plankton, fish, birds, and marine mammals. While the occurrence of plastics in surface waters has been surveyed in a number of studies, the impacts of microplastics on marine organisms are still being elucidated. This highlight features three recent publications that explore the interactions of microplastics with planktonic organisms to clarify the effects of these pollutants on some of the ocean's smallest and most important inhabitants.

    In this issue we highlight a collection of recent work in which microfluidic parallelization and automation have been employed to address the increasing need for large amounts of quantitative data concerning cellular function--from correlating microRNA levels to protein expression, increasing the throughput and reducing the noise when studying protein dynamics in single-cells, and understanding how signal dynamics encodes information. The painstaking dissection of cellular pathways one protein at a time appears to be coming to an end, leading to more rapid discoveries which will inevitably translate to better cellular control--in producing useful gene products and treating disease at the individual cell level. From these studies it is also clear that development of large scale mutant or fusion libraries, automation of microscopy, image analysis, and data extraction will be key components as microfluidics contributes its strengths to aid systems biology moving forward.

    Kim, Donghyuk; Wei, Qingshan; Kong, Janay Elise; Ozcan, Aydogan; Di Carlo, Dino

    2015-01-01

    The ability to break up a volume of fluid into smaller pieces that are confined or separated to prevent molecular communication/transport is a key capability intrinsic to microfluidic systems. This capability has been used to develop or implement digital versions of traditional molecular analysis assays, including digital PCR and digital immunoassays/ELISA. In these digital versions, the concentration of the target analyte is in a range such that, when sampled into smaller fluid volumes, either a single molecule or no molecule may be present. Subsequent amplification is sensitive enough to obtain a digital readout of the presence of these target molecules. Advantages of such approaches that are claimed include quantification without calibration and robustness to variations in reaction conditions or times because the digital readout is less sensitive to absolute signal intensity levels. Weaknesses of digital approaches include a lower dynamic range of concentrations over which the assay is sensitive, which depends on the total volume that can be analyzed. We highlight recent efforts to expand the dynamic range of digital assays based on exploiting reaction/diffusion phenomena. A side-by-side study that evaluates the strengths of digital assays reveals that the majority of these claims are supported, with specific caveats. Finally, we highlight approaches to apply digital assays to analyze new types of reactions, including the active transport of protons across membranes by ATPases at the single protein level - perhaps opening up new biophysical understanding and screening opportunities, similar to widely deployed single-molecule ion channel analysis.

    Baino, Francesco; Vitale-Brovarone, Chiara

    2014-08-01

    The benefits of ceramics in biomedical applications have been universally appreciated as they exhibit an extraordinarily broad set of physico-chemical, mechanical and biological properties which can be properly tailored by acting on their composition, porosity and surface texture to increase their versatility and suitability for targeted healthcare applications. Bioceramics have traditionally been used for the repair of hard tissues, such as bone and teeth, mainly due to their suitable strength for load-bearing applications, wear resistance (especially alumina, zirconia and composites thereof) and, in some cases, bone-bonding ability (calcium orthophosphates and bioactive glasses). Bioceramics have been also applied in other medical areas, like ophthalmic surgery; although their use in such a context has been scientifically documented since the late 1700s, the potential and importance of ceramic ocular implants still seem to be underestimated and an exhaustive, critical assessment is currently lacking in the relevant literature. The present review aims to fill this gap by giving a comprehensive picture of the ceramic-based materials and implants that are currently used in ophthalmology and pointing out the strengths and weaknesses of the existing devices. A prospect for future research is also provided, highlighting the potential of new, smart bioceramics able to carry specific added values which could have a significant impact on the treatment of ocular diseases.

    1991-01-01

    Linear instability calculations at MSFC have suggested that the Geophysical Fluid Flow Cell (GFFC) should exhibit classic baroclinic instability at accessible parameter settings. Interest was in the mechanisms of transition to temporal chaos and the evolution of spatio-temporal chaos. In order to understand more about such transitions, high resolution numerical experiments for the physically simplest model of two layer baroclinic instability were conducted. This model has the advantage that the numerical code is exponentially convergent and can be efficiently run for very long times, enabling the study of chaotic attractors without the often devastating effects of low-order trunction found in many previous studies. Numerical algorithms for implementing an empirical orthogonal function (EOF) analysis of the high resolution numerical results were completed. Under conditions of rapid rotation and relatively low differential heating, convection in a spherical shell takes place as columnar banana cells wrapped around the annular gap, but with axes oriented along the axis of rotation; these were clearly evident in the GFFC experiments. The results of recent numerical simulations of columnar convection and future research plans are presented.

    1999-01-01

    Highlights of aeroacoustics research in the United States of America during 1998 are reported in a summary compiled from information provided by members of the Aeroacoustics Technical Committee of the American Institute of Aeronautics and Astronautics (AIAA) and other leading research groups in industry, national laboratories, and academia. The past few years have seen significant progress in aeroacoustics. Research has steadily progressed toward enhanced safety, noise benefits, and lower costs. Since industrial progress is generally not published in the archival literature, it is particularly important to highlight these accomplishments. This year we chose to report on five topics of great interest to the aerospace industry including a synopsis of fundamental research at universities and national laboratories. The topics chosen are: (1) Advanced Subsonic Technology (AST), (2) High Speed Research (HSR), (3) Rotorcraft, (4) Weapons bay aeroacoustics control and (5) Academic research including Computational AeroAcoustics (CAA). Although the information presented in this review is not all encompassing we hope that the topics covered will provide some insights into aeroacoustics activity in the U.S.

  1. Ophthalmological ideas of the Byzantine author Meletius.

    Lascaratos, J; Tsirou, M

    1990-02-01

    The authors study and analyze the ophthalmological knowledge of the monk Meletius of the Monastery of St. Trinity in Tiveriopoli, as they appear in his paper 'De Natura Hominis'. The ophthalmological knowledge of Meletius mainly concerns the anatomy and physiology of the eye. The authors reach the conclusion that Meletius' ophthalmological knowledge for the greater part is compiled from that of the ancient authors; but they define a great number of pioneering medical ideas of Meletius, of which further research could discover the origin.

  4. Ophthalmology in Persian medicine

    PubMed Central

    Tabatabaei, Seyed Mahmoud; Sabetkish, Nastaran; Tabatabaei, Seyed Mohammad Ali

    2014-01-01

    Despite the fact that ophthalmology is one of the foremost branches of medicine, conceptualization of the structure and function of the eye barely advanced in ancient Western civilizations. At the early recovery of Persian civilization (9th century AD) after the extinction of the Sassanid Empire (7th century AD), translations of Greek medical textbooks played an important role in the development of medicine and the emergence of great Persian physicians such as Rhazes, Avicenna and others. Rhazes was a leading Persian physician whose medical teachings have as yet not been thoroughly explored. In addition to numerous books and articles in various fields, he authored a great medical Encyclopedia (al-Hawi al-Kabir) in 25 volumes. In this article, we are going to compare Rhazes’ particular viewpoints about ophthalmology with those of other famous Persian physicians and some recent essays and textbooks. For this purpose we reviewed Rhazes’ second volume of al-Hawi that is dedicated exclusively to ophthalmology and contains some major topics of ophthalmology including anatomy, physiology, pathology, diseases, disorders and treatments. Important themes were carefully extracted and compared with the tenets of modern ophthalmology. After collating Rhazes’ viewpoints with the latest findings in this field, it was concluded that he had brilliantly written about the signs and symptoms, etiology and treatment of many eye disorders more than a thousand years ago. The amazing point is that there was no accurate equipment at the time to help him in his investigations. This study proved that Rhazes’ theories conform to recent knowledge about ophthalmology in many aspects, and could therefore be the subject of further investigations. PMID:26587199

  5. Research highlights: natural passive samplers--plants as biomonitors.

    PubMed

    Lin, Vivian S

    2015-06-01

    In the past decade, interest in boosting the collection of data on environmental pollutants while reducing costs has spurred intensive research into passive samplers, instruments that monitor the environment through the free flow of chemical species. These devices, although relatively inexpensive compared to active sampling technologies, are often tailored for collection of specific contaminants or monitoring of a single phase, typically water or air. Plants as versatile, natural passive samplers have gained increased attention in recent years due to their ability to absorb a diverse range of chemicals from the air, water, and soil. Trees, lichens, and other flora have evolved exquisite biological features to facilitate uptake of nutrients and water from the ground and conduct gas exchange on an extraordinary scale, making them excellent monitors of their surroundings. Sampling established plant specimens in a region also provides both historical and spatial data on environmental contaminants at relatively low cost in a non-invasive manner. This Highlight presents several recent publications that demonstrate how plant biomonitoring can be used to map the distribution of a variety of pollutants and identify their sources. PMID:25980391

  11. Fee splitting in ophthalmology.

    PubMed

    Levin, Alex V; Ganesh, Anuradha; Al-Busaidi, Ahmed

    2011-02-01

    Fee splitting and co-management are common practices in ophthalmology. These arrangements may conflict with the ethical principles governing the doctor-patient relationship, may constitute professional misconduct, and at times, may be illegal. Implications and perceptions of these practices may vary between different cultures. Full disclosure to the patient may minimize the adverse effects of conflicts of interest that arise from these practices, and may thereby allow these practices to be deemed acceptable by some cultural morays, professional guidelines, or by law. Disclosure does not necessarily relieve the physician from a potential ethical compromise. This review examines the practice of fee splitting in ophthalmology, its legal implications, the policies or guidelines governing such arrangements, and the possible ethical ramifications. A comparative view between 3 countries, Canada, the United States, and Oman, was conducted; illustrating that even in disparate cultures, there may be some universality to the application of ethical principles.

    The feasibility of optoacoustic imaging was investigated for ophthalmologic application in the treatment of glaucoma. Difficulties in the treatment with laser cyclophotocoagulation are mainly due to uncertainties in the localization of the ciliary body. With laser optoacoustics it is possible to localize the position of the ciliary body on enucleated porcine and rabbit eyes. Additionally, the changes in the optical properties of the tissue induced by coagulation with a diode laser were observed.

    2010-01-01

    MRI has long been applied to clinical medical and neurological cases for the structural assessment of tissues as well as their physiological and functional needs and processes. These uses are at a variety of developmental stages in ophthalmology, from common use of clinical structural assessment for neuro-ophthalmology and evaluation of space-occupying lesions to the beginning stages of experimentally measuring functional activation of specific layers within the retina and measurement of physiological oxygen responses. New MRI methodologies, such as the use of orbital coils and Gd-DTPA image enhancement, have been researched, developed, and validated in the eye, opening new possibilities for this technology to enter the clinic. This review aims to summarize the clinical ophthalmological uses of MRI, focusing on the current use of the technology and future applications. PMID:18384176

  18. Research highlights: microfluidic-enabled single-cell epigenetics.

    PubMed

    2015-11-01

    Individual cells are the fundamental unit of life with diverse functions from metabolism to motility. In multicellular organisms, a single genome can give rise to tremendous variability across tissues at the single-cell level due to epigenetic differences in the genes that are expressed. Signals from the local environment or a history of signals can drive these variations, and tissues have many cell types that play separate roles. This epigenetic heterogeneity is of biological importance in normal functions such as tissue morphogenesis and can contribute to development or resistance of cancer, or other disease states. Therefore, an improved understanding of variations at the single cell level are fundamental to understanding biology and developing new approaches to combating disease. Traditional approaches to characterize epigenetic modifications of chromatin or the transcriptome of cells have often focused on blended responses of many cells in a tissue; however, such bulk measures lose spatial and temporal differences that occur from cell to cell, and cannot uncover novel or rare populations of cells. Here we highlight a flurry of recent activity to identify the mRNA profiles from thousands of single-cells as well as chromatin accessibility and histone marks on single to few hundreds of cells. Microfluidics and microfabrication have played a central role in the range of new techniques, and will likely continue to impact their further development towards routine single-cell epigenetic analysis.

  3. CERTS: Consortium for Electric Reliability Technology Solutions - Research Highlights

    SciTech Connect

    Eto, Joseph

    2003-07-30

    Historically, the U.S. electric power industry was vertically integrated, and utilities were responsible for system planning, operations, and reliability management. As the nation moves to a competitive market structure, these functions have been disaggregated, and no single entity is responsible for reliability management. As a result, new tools, technologies, systems, and management processes are needed to manage the reliability of the electricity grid. However, a number of simultaneous trends prevent electricity market participants from pursuing development of these reliability tools: utilities are preoccupied with restructuring their businesses, research funding has declined, and the formation of Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) to operate the grid means that control of transmission assets is separate from ownership of these assets; at the same time, business uncertainty, and changing regulatory policies have created a climate in which needed investment for transmission infrastructure and tools for reliability management has dried up. To address the resulting emerging gaps in reliability R&D, CERTS has undertaken much-needed public interest research on reliability technologies for the electricity grid. CERTS' vision is to: (1) Transform the electricity grid into an intelligent network that can sense and respond automatically to changing flows of power and emerging problems; (2) Enhance reliability management through market mechanisms, including transparency of real-time information on the status of the grid; (3) Empower customers to manage their energy use and reliability needs in response to real-time market price signals; and (4) Seamlessly integrate distributed technologies--including those for generation, storage, controls, and communications--to support the reliability needs of both the grid and individual customers.

  4. Neuro-Ophthalmological Emergencies

    PubMed Central

    Lemos, João

    2015-01-01

    Neuro-ophthalmological emergencies constitute vision or life-threatening conditions if diagnosis and treatment are not promptly undertaken. Even with immediate therapy, these clinical entities carry a high rate of morbidity. They may present with diplopia, visual loss, and/or anisocoria. Arteritic anterior ischemic optic neuropathy is an ominous condition, which can cause permanent and severe vision loss, stroke, or aortic dissection, requiring immediate steroid therapy. Pituitary apoplexy may go unnoticed if only computed axial tomography is performed. Diseases affecting the cavernous sinus and orbital apex region, such as cavernous sinus thrombosis or mucormycosis, can give rise to simultaneous vision loss and diplopia and, if not treated, may extend to the brain parenchyma causing permanent neurological sequela. An isolated third nerve palsy may be the harbinger of a cerebral aneurysm, carrying a significant risk of mortality. Horner syndrome can be the initial presentation of a carotid dissection, an important cause of stroke in the young adult. The neurohospitalist should be familiar with the workup and management of neuro-ophthalmological emergencies. PMID:26425250

  5. Hysterical symptoms in ophthalmology.

    PubMed

    Weller, M; Wiedemann, P

    1989-09-01

    Ophthalmologic symptoms are often not sufficiently accounted for by organic pathology. The complaints of these patients have been labeled hysterical, psychogenic, non-organic, or functional. The psychiatric nosology in this area may be the most confusing in the whole field of clinical medicine. The Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R) offers a classification designed to reduce non-empirical concepts and ideology to a minimum. On this background, we discuss the hysterical symptoms encountered in clinical ophthalmology with special emphasis on psychogenic amblyopia and blepharospasm. Motor symptoms are commonly not of psychogenic origin. It is suggested that ophthalmologists are most likely to treat patients with psychogenic symptoms, using suggestion, patience, and reassurance. Few patients require psychiatric consultation and a specific psychiatric therapy. The association of hysteria with organic brain disease and the issue of symptom lateralization are briefly discussed. Eventually, we reject the psychoanalytic approach and suggest that the concept of abnormal illness behavior and the neurobiological models involving corticofugal inhibition, primitive reflex mechanisms, and an attention disturbance, serve best to understand the nature of the phenomenon hysteria.

  6. Emotion Theory and Research: Highlights, Unanswered Questions, and Emerging Issues

    PubMed Central

    2009-01-01

    Emotion feeling is a phase of neurobiological activity, the key component of emotions and emotion-cognition interactions. Emotion schemas, the most frequently occurring emotion experiences, are dynamic emotion-cognition interactions that may consist of momentary/ situational responding or enduring traits of personality that emerge over developmental time. Emotions play a critical role in the evolution of consciousness and the operations of all mental processes. Types of emotion relate differentially to types or levels of consciousness. Unbridled imagination and the ability for sympathetic regulation of empathy may represent both potential gains and losses from the evolution and ontogeny of emotion processes and consciousness. Unresolved issues include psychology’s neglect of levels of consciousness that are distinct from access or reflective consciousness and use of the term “unconscious mind” as a dumpster for all mental processes that are considered unreportable. The relation of memes and the mirror neuron system to empathy, sympathy, and cultural influences on the development of socioemotional skills are unresolved issues destined to attract future research.

    The Surface Analysis project provides measurement support and leadership for collaborative research activities involving surface chemistry and physics in all areas of the PV program. Significant results from the past fiscal year include the following: i) in-situ XPS, UPS, and AES studies of chemical-bath exposure of CIGS surfaces demonstrated that Group-III elements are preferentially removed from the surface, that type conversion of the surface occurs, and that the addition of a surfactant improves CdS deposition and thus device performance; ii) XPS studies of polyethylene terephthalate (PET) candidate backsheet materials have shown that plasma exposure prior to oxide-barrier deposition results in the formation of low-molecular-weight fragments that result in the formation of a weak interfacial layer that fails during damp-heat exposure; iii) an empirical relation was derived for the source geometry that leads to optimal film-thickness uniformity in rotating-substrate physical-vapor deposition (PVD) systems; and iv) PVD flux-distribution calculations were performed to develop a novel method for combinatorial thin-film synthesis.

    Raw fossil material reserves are not inexhaustible and as prices continue to raise it is necessary to find new sources of alternative and renewable energy. Oils from oleaginous field crops (sunflower and rape) with properties close to those of fossil fuel could constitute an alternative source of energy for the production of raw materials. This is the context in which the 18th International Symposium on Plant lipids (ISPL) was held in Bordeaux from 20th to 25th July 2008 at "La Cité Mondiale". The 18th ISPL gathered 270 researchers from 33 countries. Sixty nine oral communications and 136 posters were presented during the 12 sessions of the Symposium. The sessions have covered all the different aspects of the Plant Lipid field including: Surface lipids: suberin, cutin and waxes, Fatty acids, Glycerolipids, Plant lipids as renewable sources of energy, Seed oils and bioengineering of metabolic pathways, Lipid catabolism, Models for lipid studies: lower plants, micro-organisms and others, Modifications of proteins by lipids, Sphingolipids, sterols and isoprenoids, Lipid signaling and plant stress responses, Lipid trafficking and membrane dynamics, New methods and technologies: functional lipidomics, fluxome, modelling. During the ISPL 2008 Bordeaux, important and new information was reported in the different fields. A selection of these results is presented here. PMID:19328004

    The National Spherical Torus Experiment (NSTX) is a collaborative mega-ampere-class spherical torus research facility with high power heating and current drive systems and the state-of-the-art comprehensive diagnostics. For the 2008 experimental campaign, the high harmonic fast wave (HHFW) heating efficiency in deuterium improved significantly with lithium evaporation and produced a record central Te of 5 keV. The HHFW heating of NBI-heated discharges was also demonstrated for the first time with lithium application. The EBW emission in H-mode was also improved dramatically with lithium which was shown to be attributable to reduced edge collisional absorption. Newly installed FIDA energetic particle diagnostic measured significant transport of energetic ions associated with TAE avalanche as well as n=1 kink activities. A full 75 channel poloidal CHERS system is now operational yielding tantalizing initial results. In the near term, major upgrade activities include a liquid-lithium divertor target to achieve lower collisionality regime, the HHFW antenna upgrades to double its power handling capability in H-mode, and a beam-emission spectroscopy diagnostic to extend the localized turbulence measurements toward the ion gyro-radius scale from the present concentration on the electron gyro-radius scale. For the longer term, a new center stack to significantly expand the plasma operating parameters is planned along with a second NBI system to double the NBI heating and CD power and provide current profile control. These upgrades will enable NSTX to explore fully non-inductive operations over a much expanded plasma parameter space in terms of higher plasma temperature and lower collisionality, thereby significantly reducing the physics parameter gap between the present NSTX and the projected next-step ST experiments.

    Exposure of the human body to ambient pressures greater than that at sea level may result in various disorders, some of which have ocular manifestations. Additionally, some eye disorders and postoperative states may be adversely affected by the underwater environment or other hyperbaric exposures. The prevalence of recreational, military, and commercial diving, as well as the medical use of hyperbaric oxygen therapy, requires that ophthalmologists be familiar with the effects of the hyperbaric environment on the normal and diseased eye. The ophthalmology and diving medical literatures were surveyed for publications relating to the ophthalmic aspects of diving and hyperbaric exposures. Underwater optics, underwater refractive correction, and ophthalmic aspects of a fitness-to-dive evaluation are summarized.

    Preservatives are a legal requirement for eye drops in multidose containers. Moreover, they are necessary for stabilization and intraocular penetration for a number of ophthalmic preparations. Most preservatives act in a relatively unspecific manner as detergents or by oxidative mechanisms and thereby cause side effects at the ocular surface. They may also affect the lens, trabecular meshwork and the retina. Benzalkonium chloride is the most commonly used preservative in ophthalmology and is more toxic than other or newer preservatives, such as polyquaternium-1 (Polyquad), sodium perborate, oxychloro-complex (Purite®) and SofZia. Preservative-free topical medication is highly recommended for patients with ocular surface disease, frequent eye drop administration, proven allergy to preservatives and contact lens wear.

    Suturing is a time consuming task in ophthalmology and suture induced irritation and redness are frequent problems. Postoperative wound infection and corneal graft rejection are examples of possible suture related complications. To prevent these complications, ophthalmic surgeons are switching to sutureless surgery. A number of recent developments have established tissue adhesives like cyanoacrylate glue and fibrin glue as attractive alternatives to sutures. A possible and promising new application for tissue adhesives is to provide a platform for tissue engineering. Currently, tissue glue is being used for conjunctival closure following pterygium and strabismus surgery, forniceal reconstruction surgery, amniotic membrane transplantation, lamellar corneal grafting, closure of corneal perforations and descematoceles, management of conjunctival wound leaks after trabeculectomy, lid surgery, adnexal surgery and as a hemostat to minimise bleeding. The purpose of this review is to discuss the currently available information on fibrin glue. PMID:19700876

    In the past three decades, there have been countless advances in imaging modalities that have revolutionized evaluation, management, and treatment of neuro-ophthalmic disorders. Non-invasive approaches for early detection and monitoring of treatments have decreased morbidity and mortality. Understanding of basic methods of imaging techniques and choice of imaging modalities in cases encountered in neuro-ophthalmology clinic is critical for proper evaluation of patients. Two main imaging modalities that are often used are computed tomography (CT) and magnetic resonance imaging (MRI). However, variations of these modalities and appropriate location of imaging must be considered in each clinical scenario. In this article, we review and summarize the best neuroimaging studies for specific neuro-ophthalmic indications and the diagnostic radiographic findings for important clinical entities.

    2010-01-01

    More than a century after the first successful use of serotherapy, antibody-based therapy has been renewed by the availability of recombinant monoclonal antibodies. As in the past, current clinical experience has prompted new pharmacological questions and induced much debate among practitioners, notably in the field of ophthalmology. An examination of the history of antibodies as treatments for ocular disorders reveals interesting parallels to the modern era. The fact that a treatment administered by a systemic route could be efficacious in a local disease was not widely accepted and the “chemical” nature of antibodies was not clearly understood in the late 19th century. Clinical studies by Henry Coppez, a Belgian ophthalmologist, established in 1894 that antidiphtheric antitoxins could be used to treat conjunctival diphtheria. Nearly 20 years later, Coppez and Danis described age-related macular degeneration, a disorder which today benefits from ranibizumab therapy. The product, a locally-administered recombinant monoclonal Fab fragment, is directed against vascular endothelial growth factor A. Interestingly, its full-size counterpart, bevacizumab, which is approved for the treatment of solid tumors, has also demonstrated efficacy in age-related macular degeneration when administered either intravenously or locally, which raises new questions about antibody pharmacology and biodistribution. In order to shed some light on this debate, we recount the early history of serotherapy applied to ophthalmology, review the exact molecular differences between ranibizumab and bevacizumab, and discuss what is known about IgG and the blood-retina barrier and the possible role of FcRn, an IgG transporter.

    Information systems managing image-based data for telemedicine or clinical research applications require a reference standard representing the correct diagnosis. Accurate reference standards are difficult to establish because of imperfect agreement among physicians, and discrepancies between clinical vs. image-based diagnosis. This study is designed to describe the development and evaluation of reference standards for image-based diagnosis, which combine diagnostic impressions of multiple image readers with the actual clinical diagnoses. We show that agreement between image reading and clinical examinations was imperfect (689 [32%] discrepancies in 2148 image readings), as was inter-reader agreement (kappa 0.490-0.652). This was improved by establishing an image-based reference standard defined as the majority diagnosis given by three readers (13% discrepancies with image readers). It was further improved by establishing an overall reference standard that incorporated the clinical diagnosis (10% discrepancies with image readers). These principles of establishing reference standards may be applied to improve robustness of real-world systems supporting image-based diagnosis. PMID:25954463

    Sun, X D; Zhu, H

    2016-02-01

    Accompany with dramatically growth of large-scale biological databases (such as human genome sequence), improvement of life science and development of international clinical trials, science offers great potential for improving health care through precision medicine. As a hot topic recently, precision medicine might launch a revolution of the methodology in medical research. How to achieve precision medicine in clinical ophthalmology by means of biological data mining is a challenge for ophthalmologist-scientists. The best approach for advanced individual medicine is to buildup the digital ophthalmology, which includes human eye biobank, national biological databases network, clinical department, basic research lab, and international clinical trial center. The system of digital ophthalmology could explore the methods for ophthalmology research, integrate the source of eye biologic databases, promote international cooperation, and thus eventually supply the opportunity for translational medicine.

    Ribeiro, Paulo A.

    1992-03-01

    The clinical application of lasers in ophthalmology is schematized, showing for each anatomic eye structure, pathologies that may be treated through this procedure. In the cornea, the unusual laser practice for suture removals and the promising possibility of the excimer laser in refractive surgery are discussed. In the iris, the camerular angle, and the ciliary body, the laser application is essentially used to treat the glaucoma and other situations that are not so frequent. The capsulotomy with YAG LASER is used in the treatment of structures related with crystalline and, at least, the treatment of the retina and choroid pathology is expanded. A. A. explained the primordial interest and important of laser in the diabetic retinopathy treatment and some results in patients with more than 5 years of evolution are: 55 of the patients with proliferative diabetic retinopathy (RDP) treated for more than 5 years noticed their vision improved or stabilized; 5 years after treating patients with PDR, 49.3 had their vision stabilized or even improved, provided the diabetics had declared itself more than 20 years ago, versus 61.7 provided the diabetics had declared itself less than 20 years before; finally, 53.8 of the patients under 40-years-old when the diabetics was diagnosed, had their vision improved or at least stabilized 5 years after the beginning of the treatment. On the other side, when patients were over 40 years old when the diabetics was diagnosed percentage increased to 55.9. This study was established in the follow-up of 149 cases over 10 years.

    Retinal oximeter is a new machine which has been used in the diagnose, treatment and research of several ophthalmic diseases for recent years. It allows ophthalmologists to gain retinal oxygen saturation directly. Therefore, retinal oximeter might be useful for ophthalmologists to understand ophthalmic diseases more deeper and clarify the impact of ischemia on retinal function. It has been reported in the literatures that retinal oximeter has potentially useful diagnostic and therapeutic indications in various eye diseases such as diabetic retinopathy, central retinal vein and artery occlusion, retinitis pigmentosa, glaucomatous optic neuropathy, et al. In this thesis, the application of retinal oximeter in ophthalmology is reviewed. PMID:26850588

    Purpose: To analyze organization of ophthalmology health care in Tuzla canton and use of information technologies(IT). Introduction: IT in ophthalmology is the technology required for the data processing and other information important for patient and essential for building an electronic health record(EHR). IT in ophthalmology should include the study, science, and solution sets for all aspects of data, information and knowledge management in health information processing. Material and methods: We have analyzed organization of ophthalmology health care in Tuzla canton. Data relevant for this research were acquired from annual reports of Tuzla Canton health ministry. All institutions and ambulances were visited and all health care professionals interviewed. A questionnaire was made which included questions for health care professionals about knowledge and use of computers, internet and information technology. Results: Ophthalmology health care in Tuzla canton has paper based medical record. There is no information system with any possibility to exchange data electronically. None of the medical devices is directly connected to the Internet and all data are typed, printed and delivered directly to the patient. All interviewed health care professionals agree that implementation of IT and EHR would contribute and improve work quality. Conclusion: Computer use and easy information access will make a qualitative difference in eye-care delivery in Tuzla canton. Implementation phase will be difficult because it will likely impact present style of practice. Strategy for implementation of IT in medicine in general must be made at the country level.

    Considering patients' values and preferences in comparative effectiveness research (CER) is one of the main challenges in ophthalmology (value-based medicine). This article defines core terms in CER. The concept of patient-relevant (or patient-important) outcomes is distinguished from patient-reported outcomes (PRO) by means of examples in the field of ophthalmology. In order to be able to give a consistant recommendation if an intervention leads to conflicting results for different outcomes (trade-off), a ranking of outcomes will be necessary. Examples of studies in glaucoma patients are provided that demonstrate the possibilities of ranking of outcomes based on patient preferences. PMID:20024566

    Due to their complexity and wide-ranging utility, biomacromolecular research is an especially interdisciplinary branch of chemistry. It is my goal that the Biomacromolecules subject area of Chemistry Central Journal will parallel this richness and diversity. In this inaugural commentary, I attempt to set the stage for achieving this by highlighting several areas where biomacromolecular research overlaps more traditional chemistry sub-disciplines. Specifically, it is discussed how Materials Science and Biotechnology, Analytical Chemistry, Cell Biology and Chemical Theory are each integral to modern biomacromolecular research. Investigators with reports in any of these areas, or any other dealing with biomacromolecules, are encouraged to submit their research papers to Chemistry Central Journal. PMID:17939851

  11. Air Force Research Laboratory (AFRL) research highlights, September--October 1998

    1998-10-01

    New AFOSR-sponsored research shows that exhausts from solid-fueled rocket motors have very limited impact on stratospheric ozone. The research provides the Air Force with hard data to support continued access to space using the existing fleet of rockets and rocket technology. This basic research data allows the Air Force to maintain a strongly proactive environmental stance, and to meet federal guidelines regarding environmental impacts. Long-standing conjecture within the international rocket community suggests that chlorine compounds and alumina particulates produced in solid rocket motor (SRM) exhausts could create localized, temporary ozone toss in rocket plumes following launches. The extent of a local depletion of ozone and its environmental impact depends on details of the composition and chemistry in these plumes. Yet direct measurements of plume composition and plume chemistry in the stratosphere had never been made. Uncertainty about these details left the Air Force and commercial space launch capability potentially vulnerable to questions about the environmental impact of rocket launches. In 1995, APOSR and the Space and Missiles Systems Center Launch Programs Office (SMC/CL) jointly began the Rocket Impacts on Stratospheric Ozone (RISO) program to make the first-ever detailed measurements of rocket exhaust plumes. These measurements were aimed at understanding how the exhaust from large rocket motors effect the Earth`s stratospheric ozone layer. The studies determined: the size distribution of alumina particles in these exhausts, the amount of reactive chlorine in SRM exhaust, and the size and duration of localized ozone toss in the rocket plumes.

  13. Understanding Energy Impacts of Oversized Air Conditioners; NREL Highlights, Research & Development, NREL (National Renewable Energy Laboratory)

    SciTech Connect

    2015-06-01

    This NREL highlight describes a simulation-based study that analyzes the energy impacts of oversized residential air conditioners. Researchers found that, if parasitic power losses are minimal, there is very little increase in energy use for oversizing an air conditioner. The research demonstrates that new residential air conditioners can be sized primarily based on comfort considerations, because capacity typically has minimal impact on energy efficiency. The results of this research can be useful for contractors and homeowners when choosing a new air conditioner or heat pump during retrofits of existing homes. If the selected unit has a crankcase heater, performing proper load calculations to be sure the new unit is not oversized will help avoid excessive energy use.

    2013-01-01

    Simulation can be defined as malingering, or sometimes functional visual loss (FVL). It manifests as either simulating an ophthalmic disease (positive simulation), or denial of ophthalmic disease (negative simulation). Conscious behavior and compensation or indemnity claims are prominent features of simulation. Since some authors suggest that this is a manifestation of underlying psychopathology, even conversion is included in this context. In today's world, every ophthalmologist can face with simulation of ophthalmic disease or disorder. In case of simulation suspect, the physician's responsibility is to prove the simulation considering the disease/disorder first, and simulation as an exclusion. In simulation examinations, the physician should be firm and smart to select appropriate test(s) to convince not only the subject, but also the judge in case of indemnity or compensation trials. Almost all ophthalmic sensory and motor functions including visual acuity, visual field, color vision and night vision can be the subject of simulation. Examiner must be skillful in selecting the most appropriate test. Apart from those in the literature, we included all kinds of simulation in ophthalmology. In addition, simulation examination techniques, such as, use of optical coherence tomography, frequency doubling perimetry (FDP), and modified polarization tests were also included. In this review, we made a thorough literature search, and added our experiences to give the readers up-to-date information on malingering or simulation in ophthalmology. PMID:24195054

    Atmospheric particles are emitted from a variety of anthropogenic and natural precursors and have direct impacts on climate, by scattering solar irradiation and nucleating clouds, and on health, by causing oxidative stress in the lungs when inhaled. They may also form from gaseous precursors, creating complex mixtures of organic and inorganic material. The chemical composition and the physical properties of aerosols will evolve during their one-week lifetime which will consequently change their impact on climate and health. The heterogeneity of aerosols is difficult to model and thus atmospheric aerosol research strives to characterize the mechanisms involved in nucleating and transforming particles in the atmosphere. Recent advances in four laboratory studies of aerosol formation and aging are highlighted here. PMID:27050080

    2011-10-01

    On the one hundredth anniversary of the discovery of the nucleus, selected highlights in nuclear research by Vanderbilt scientists and by Oak Ridge National Laboratory scientists as well as their joint research are described. These will include the earliest work involving the first confirmation of neutron induced fission and classic papers on the fission process. This was followed by the development of the barrier for the gaseous diffusion separation of ^235U from ^238U. In the 1940's the first working nuclear reactor became operational at ORNL, to make ^239Pu followed by the first radioisotopes for nuclear medicine, neutron scattering to probe materials leading to a Nobel Prize and the first observation of the β decay of the free neutron. In 1953 Hill and Wheeler published their classic nuclear theory paper that has over 2000 citations. In the 1960's large E0 transitions were observed in decays of β but not γ vibrational bands to confirm the predictions of Bohr and Mottelson that β vibrations change the nuclear deformation. Then the first failures of the B-M model were observed. In the 1970's the paradigm that each nucleus had one fixed shape was changed when the discovery of the coexistence of overlapping bands built on different deformations were observed. This was made possible, in part, by universities building the first isotope separator on-line to the Oak Ridge cyclotron. This was followed by the discovery of the reinforcement of proton and neutron shell gaps at the same deformation to give superdeformed double magic nuclei. Other highlights will be presented, including the recent discovery of the new element 117 and confirmation of new elements 113 and 115.

  3. Emerging roles for microtubules in angiosperm pollen tube growth highlight new research cues

    2015-01-01

    In plants, actin filaments have an important role in organelle movement and cytoplasmic streaming. Otherwise microtubules (MTs) have a role in restricting organelles to specific areas of the cell and in maintaining organelle morphology. In somatic plant cells, MTs also participate in cell division and morphogenesis, allowing cells to take their definitive shape in order to perform specific functions. In the latter case, MTs influence assembly of the cell wall, controlling the delivery of enzymes involved in cellulose synthesis and of wall modulation material to the proper sites. In angiosperm pollen tubes, organelle movement is generally attributed to the acto-myosin system, the main role of which is in distributing organelles in the cytoplasm and in carrying secretory vesicles to the apex for polarized growth. Recent data on membrane trafficking suggests a role of MTs in fine delivery and repositioning of vesicles to sustain pollen tube growth. This review examines the role of MTs in secretion and endocytosis, highlighting new research cues regarding cell wall construction and pollen tube-pistil crosstalk, that help unravel the role of MTs in polarized growth.

The characteristics of their 5-year training assured by numerous teachers and short training rotations as well as by a compulsory research project are explained. They highlight the meticulous organization and the compulsory constraints for students, teachers and universities. In absence of evaluation criteria on the efficiency of interventionist training compared to less detailed apprenticeship-program training such as that dispensed in France, they note the differences between the two systems, a necessary precursor to the standardization of training programs which would allow more complete recognition of degrees in the context of a globalization of professional activities.

    2010-01-01

    Mitochondrial diseases frequently manifest neuro-ophthalmologic symptoms and signs. Because of the predilection of mitochondrial disorders to involve the optic nerves, extraocular muscles, retina, and even the retrochiasmal visual pathways, the ophthalmologist is often the first physician to be consulted. Disorders caused by mitochondrial dysfunction can result from abnormalities in either the mitochondrial DNA or in nuclear genes which encode mitochondrial proteins. Inheritance of these mutations will follow patterns specific to their somatic or mitochondrial genetics. Genotype-phenotype correlations are inconstant, and considerable overlap may occur among these syndromes. The diagnostic approach to the patient with suspected mitochondrial disease entails a detailed personal and family history, careful ophthalmic, neurologic, and systemic examination, directed investigations, and attention to potentially life-threatening sequelae. Although curative treatments for mitochondrial disorders are currently lacking, exciting research advances are being made, particularly in the area of gene therapy. Leber hereditary optic neuropathy, with its window of opportunity for timely intervention and its accessibility to directed therapy, offers a unique model to study future therapeutic interventions. Most patients and their relatives benefit from informed genetic counseling. PMID:20471050

    Future ophthalmologists will need to have broad skills to thrive in complex health care organizations. However, training for ophthalmologists does not take advantage of all of the postgraduate years (PGYs). Although the traditional residency years seem to have little excess capacity, enhancing the internship year does offer an opportunity to expand the time for ophthalmology training in the same 4 PGYs. Integrating the internship year into residency would allow control of all of the PGYs, allowing our profession to optimize training for ophthalmology. In this white paper, we propose that we could capture an additional 6 months of training time by integrating basic ophthalmology training into the intern year. This would allow 6 additional months to expand training in areas such as quality improvement or time for "mini-fellowships" to allow graduates to develop a deeper set of skills. PMID:27423312

    PubMed

    Pérez-Blázquez, Esther Ezquerro; Redondo, Mi; García, T

    2008-01-01

    The appearance of the Acquired Immune Deficiency Syndrome (AIDS) meant a revolution in medicine, which has also affected Ophthalmology: the routine presence of ophthalmological pathologies which until then had been exceptional, such as retinitis due to cytomegalovirus (CMV), and the appearance of other new pathologies such as progressive outer retinal necrosis (PORN). The generalised use of high activity antiretroviral therapy (HAART) in the second half of the 1990s represented a turning point, since when the immunological improvement of patients with Human Immunodeficiency Virus (HIV) resulted in a fall in the cases with ophthalmological pathology associated to immunodepression (HIV retinopathy, retinitis due to CMV, PORN...), and the spontaneous improvement of symptoms which until then had had a torpid evolution (Kaposi's ocular sarcoma, Palpebral Molluscum...). On the other hand, the continuous increase in the prevalence of syphilis in these patients means an increase in the number of cases of ocular syphilis unassociated with immunodepression. New ophthalmological alterations also appear that are related to HAART: uveitis due to immune recovery in patients with CMV retinitis in complete remission and the enophthalmos due to the atrophy of orbital fat in the context of lipodystrophy, associated with antiretrovirals. At present preventive ophthalmological checks must be carried out on patients with severe immunodepression until a count of lymphocytes above 100 cells/microl is confirmed. If they also show HIV retinopathy, a monthly check up is advisable until immune recovery, given the greater risk of infection by CMV. PMID:19169296

    1993-02-01

    The ophthalmologic safety of antimalarial drugs is well established, but absolute safety cannot be assured. Three types of side effects may develop. Corneal deposits and neuromuscular-associated blurred vision are always reversible and therefore benign. Visual loss has occurred in patients with retinopathy. Retinopathy may be divided into true retinopathy and premaculopathy. It is true retinopathy that may be associated with visual loss, while premaculopathy consists of subtle visual field and funduscopic abnormalities. These premaculopathic changes are generally completely reversible with drug discontinuation and have not been shown to progress. Hydroxychloroquine appears safer than chloroquine when currently accepted equivalent doses are used. Fewer than 20 patients with true retinopathy caused by hydroxychloroquine have been reported; more patients have developed true retinopathy when taking chloroquine. The safety profile is most dependent on low daily dose and regular ophthalmologic monitoring. The optimal strategy of ophthalmologic testing has not yet been determined, but visual acuity, funduscopic examination and visual field examination should be monitored. Self-administered ophthalmologic testing with Amsler grids may contribute additional safety but is not a replacement for physician testing. PMID:8485566

    Treatment guidance for non-multidrug-resistant (MDR) rifampicin-resistant (RMP-R) tuberculosis (TB) is variable. We aimed to undertake a systematic review and meta-analysis of the randomised controlled trial (RCT) data behind such guidelines to identify the most efficacious treatment regimens. Ovid MEDLINE, the Web of Science and EMBASE were mined using search terms for TB, drug therapy and RCTs. Despite 12 604 records being retrieved, only three studies reported treatment outcomes by regimen for patients with non-MDR RMP-R disease, preventing meta-analysis. Our systematic review highlights a substantial gap in the literature regarding evidence-based treatment regimens for RMP-R TB. PMID:27287636

    MELODI is the European platform dedicated to low-dose radiation risk research. From 7 October through 10 October 2013 the Fifth MELODI Workshop took place in Brussels, Belgium. The workshop offered the opportunity to 221 unique participants originating from 22 countries worldwide to update their knowledge and discuss radiation research issues through 118 oral and 44 poster presentations. In addition, the MELODI 2013 workshop was reaching out to the broader radiation protection community, rather than only the low-dose community, with contributions from the fields of radioecology, emergency and recovery preparedness, and dosimetry. In this review, we summarise the major scientific conclusions of the workshop, which are important to keep the MELODI strategic research agenda up-to-date and which will serve to establish a joint radiation protection research roadmap for the future.

    Avian biology was a major component of early research and baseline surveys. The focus of research shifted and the SRS evolved from open fields to forest cover. In the early years avian species richness and abundance increased with successional age of the vegetation from old-field to forest. During the early years resident game birds increased. More recent studies will help to understand the role of habitat in local and regional extinctions. A variety of survey techniques is needed.

    The fifth biennial Berry Health Benefits Symposium showcased recent research supporting the positive effects of berry consumption on human health and disease. Remarkably, the vast majority of oral papers covered data accumulated from in vivo studies, which underscores how berry health research has advanced since the inception of this symposium in 2005. Similar to the past, research presented at this meeting was primarily focused on the major commercially cultivated berries in North America, namely, blackberry, blueberry, black raspberry, cranberry, red raspberry, and strawberry. Despite this, on the basis of similar compositional chemistry, it is possible that similar biological effects may also be extended to other small soft-fleshed "berry-type" fruits popular in other parts of the world including Europe, Asia, and South America. Overall, this symposium continues to add to the growing body of data supporting the positive impact of berry fruit consumption on human health promotion and disease risk reduction. PMID:24148006

    The field of Physics Education Research (PER) has for over thirty years provided insights into student thinking and guided the development and assessment of reformed teaching strategies and practices in introductory physics courses. In the last decade or so, researchers have expanded the domain of such investigations to upper-division courses where undergraduate majors study more advanced content and begin to see themselves as future physicists. The upcoming Focused Collection on Upper Division PER brings together work from researchers active in these new frontiers of PER. In this presentation we provide an overview of the studies in this collection, which offer to the PER and greater physics education communities: new insights about the thinking, behavior, and beliefs of students in the upper division; new tools to innovate instruction, assess student learning, and evaluate teaching effectiveness; and groundbreaking studies of identity development and ``thinking like a physicist'' among physics majors. In this session we also recognize the ten-year anniversary of Physical Review Special Topics: Physics Education Research, an occasion that we will celebrate with an informal reception immediately following the conclusion of this invited session.

    In response to the need for research infrastructure in hydrologic sciences, a group of over 35 universities has formed a Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI). With support from the U.S. National Science Foundation, CUAHSI has initiated a science planning process aimed at building research infrastructure in three main areas: i) Long Term Hydrologic Observatories, to provide the consistent, integrated, long-term information from point to continental scales ii) a Hydrologic Information System program, to support the data, information, and analysis requirements of the community and iii) a Hydrologic Measurement Technology program to develop and operate state-of-the-art systems and provide support services for hydrologic research. Scientifically, this infrastructure initiative aims to support research to provide new understanding about priority questions in hydrologic and related sciences, including: i) spatial and temporal properties of precipitation and snow processes, ii) surface water generation and transport at scales from hectares to continental-scale basins, iii) linked water, carbon and other chemical cycles, and changes in response to varying temperature, precipitation and land-use patterns, iii) environmental stresses on aquatic and riparian ecosystems related to groundwater pumping and other perturbations, iv) basin-scale subsurface water and solute movement, particularly as related to patterns of precipitation, evapotranspiration and recharge, and v) feedback between regional evaporation and transpiration and patterns of precipitation and humidity. It has become apparent that the science infrastructure in hydrologic and related sciences is currently inadequate to meet many of these priority science questions and societal needs. Specifically, investments are needed to: i) maintain, supplement and upgrade existing field facilities, ii) establish measurement programs that can deliver consistent data over the long

    Microstructure determines the yield of free charge in neat semiconducting polymers. Understanding the fundamental photophysics of poly(3-hyxylthiophene) films, and that of conjugated polymers in general, is essential if we are to realize their full potential as low-cost active layers for coal-competitive solar power generation. Yet, the value of one of the most basic photophysical parameters of these materials - the yield of free charges upon photoexcitation of neat films - has remained controversial because of a wide variation between previous measurements. Researchers at the National Renewable Energy Laboratory (NREL) have resolved this controversy by showing that the yield of free charges depends sensitively on the solid-state microstructure of the film. The microstructure was varied systematically through control of the polymers molecular weight and processing conditions, while the charge carrier yield was measured using time-resolved microwave conductivity - a unique technique to which only a few groups in the world have access. The researchers found that the yield of long-lived free charges depends on the co-existence of amorphous and crystalline domains in the polymer, and this behavior was attributed to charge separation at the interface between these two domains of order.

    The FP7 DRIHM (Distributed Research Infrastructure for Hydro-Meteorology, http://www.drihm.eu, 2011-2015) project intends to develop a prototype e-Science environment to facilitate the collaboration between meteorologists, hydrologists, and Earth science experts for accelerated scientific advances in Hydro-Meteorology Research (HMR). As the project comes to its end, this presentation will summarize the HMR results that have been obtained in the framework of DRIHM. The vision shaped and implemented in the framework of the DRIHM project enables the production and interpretation of numerous, complex compositions of hydrometeorological simulations of flood events from rainfall, either simulated or modelled, down to discharge. Each element of a composition is drawn from a set of various state-of-the-art models. Atmospheric simulations providing high-resolution rainfall forecasts involve different global and limited-area convection-resolving models, the former being used as boundary conditions for the latter. Some of these models can be run as ensembles, i.e. with perturbed boundary conditions, initial conditions and/or physics, thus sampling the probability density function of rainfall forecasts. In addition, a stochastic downscaling algorithm can be used to create high-resolution rainfall ensemble forecasts from deterministic lower-resolution forecasts. All these rainfall forecasts may be used as input to various rainfall-discharge hydrological models that compute the resulting stream flows for catchments of interest. In some hydrological simulations, physical parameters are perturbed to take into account model errors. As a result, six different kinds of rainfall data (either deterministic or probabilistic) can currently be compared with each other and combined with three different hydrological model engines running either in deterministic or probabilistic mode.

    The NEES@UCSB facility consists of experimental facilities and cyber infrastructure for active testing and passive earthquake monitoring at instrumented geotechnical field sites. There have been a number of facility enhancements to both the experimental facilities and the cyber infrastructure for facilitating research at the sites and access to the data they produce. Through both the maintenance and operations and the NEES Research program funding sources, the scope of monitoring at the field sites continues to expand. A permanent cross-hole source and sensor array has been installed at both the Wildlife Liquefaction Array (WLA) and at the Garner Valley Downhole Array (GVDA) field sites. This enhancement provides daily measurements of shear-wave velocity and automated post-earthquake observations of velocity to examine soil modulus reduction and recovery. After a very large event, where nonlinear soil behavior is expected, cross-hole hammer source time intervals are as short as 5 minutes. While waiting for larger earthquakes to occur, the daily cross-hole hammer tests are providing interesting data on shear-wave velocity changes with seasonal water table height. Testing of a small reconfigurable structure at both the WLA and GVDA sites was conducted using the NEES@UCLA mobile shakers. The structure, which is a smaller version of a permanent structure at GVDA, has been left at the GVDA site and can be used for future experiments or site instrumentation enhancements. The large soil-foundation-interaction structure at GVDA has a 1D shaker mounted under its roof slab. This shaker runs nightly and the data provide insight into the influence of environmental conditions on the response of the structure. At WLA, additional sensors have been installed in a dense Shape Accelerometer Array (SAA). Each of the seven arrays contain 24 3-component MEMS accelerometers at approximately 0.3 meter spacing that span the upper 8 meters of the site, from above to below the liquefiable

    The Varroa mite (Varroa destructor) is implicated as a major disease factor in honey bee (Apis mellifera) populations worldwide. Honey bees are extensively relied upon for pollination services, and in countries such as New Zealand and Australia where honey bees have been introduced specifically for commercial pollinator services, the economic effects of any decline in honey bee numbers are predicted to be profound. V. destructor established in New Zealand in 2000 but as yet, Australia remains Varroa-free. Here we analyze the history of V. destructor invasion and spread in New Zealand and discuss the likely long-term impacts. When the mite was discovered in New Zealand, it was considered too well established for eradication to be feasible. Despite control efforts, V. destructor has since spread throughout the country. Today, assessing the impacts of the arrival of V. destructor in this country is compromised by a paucity of data on pollinator communities as they existed prior to invasion. Australia's Varroa-free status provides a rare and likely brief window of opportunity for the global bee research community to gain understanding of honey bee-native pollinator community dynamics prior to Varroa invasion.

    We examined 65 (61 female and 4 male) Takayasu patients. Patient age ranged from 17 to 78 years old (mean 50.2); age of onset was from 11 to 60 years old (mean 32.8); and duration from onset to referral ranged from 1 month to 43 years (mean 16.8 years). Routine ophthalmological examinations were performed. Fluorescein angiography, kinetic perimetry by Goldmann perimetry, static perimetry by Octopus 1-2-3, electroretinography (ERG), and measurements of central retinal arterial pressure were also performed, as appropriate. Major causes of impaired visual acuity (less than 16/20) were cataract. A few patients had low visual acuity caused by Takayasu disease itself. On the other hand, although not many complained of visual disturbance, about 35% of patients had subnormal visual functions. Because the visual deterioration may be based on ocular hypoperfusion, which may subsequently lead to more serious changes, regular ophthalmological examination for every Takayasu disease patient is recommended.

    Studying of functional aspects of eye disease pathogenesis by electrophysiological methods is widely demanded in fundamental ophthalmology. Introduction of modern methods of functional assessment into experimental and clinical projects significantly broadens knowledge of normal and pathological functioning of the visual system and is the basis for further development of new strategies of pathogenetic treatment, diagnostics and expert evaluation. Some problems of ophthalmology, including those that concern age-related macular degeneration, glaucoma, diabetic retinopathy, and other diseases, are considered in the context of how much electrophysiology contributes to their solution. The role of functional examinations of the retina in studying pathophysiology of neurodegenerative brain diseases, such as Alzheimer's and Parkinson's, is also discussed. PMID:25715550

    2012-01-01

    Imaging the eye with magnetic resonance imaging (MRI) has proved difficult due to the eye’s propensity to move involuntarily over typical imaging timescales, obscuring the fine structure in the eye due to the resulting motion artifacts. However, advances in MRI technology help to mitigate such drawbacks, enabling the acquisition of high spatiotemporal resolution images with a variety of contrast mechanisms. This review aims to classify the MRI techniques used to date in clinical and preclinical ophthalmologic studies, describing the qualitative and quantitative information that may be extracted and how this may inform on ocular pathophysiology.

    Aims Cognitive factors (eg, academic achievement) have had a significant role in selecting postgraduate surgical trainees in the past. This project sought to determine the role of a national undergraduate ophthalmology prize examination (Duke–Elder examination) in the selection of postgraduate ophthalmology trainees. This would also serve as a quality assurance exercise for the assessment, in which the ultimate aim is to encourage trainees into ophthalmology. Methods A retrospective analysis of the top 20 ranked candidates in the Duke–Elder examination from 1989 to 2005 (except 1995) was carried out to determine which of them subsequently entered the ophthalmic training and General Medical Council Specialist Registers. Results Out of the top 20 candidates in the exam, 29.5% went into specialist training in ophthalmology. Some appeared in the top 20 more than once, with 56% of them going into ophthalmic training, but they had a similar median time to enter training as those who appeared in the top 20 once. There was no significant evidence to suggest that the overall median ranking scores between the UK medical schools differed (P=0.23; Kruskal–Wallis test). However, there was a marked difference in frequency of top 20 candidates from each medical school, which could not be explained by the size of the medical school alone. Conclusion It is difficult to conclude from these findings the importance that the Duke–Elder examination has in the selection of trainees into ophthalmology. The role of cognitive factors in selection into postgraduate medical/surgical training is discussed, along with the potential academic criteria, which may influence interview scores. PMID:21587276

    PubMed

    Jaeger, W

    1986-02-01

    Until the beginning of the 17th century it was held that an image is formed in the eye on the anterior surface of the crystalline lens. Ophthalmological optics as a scientific discipline only began with a discovery made by Johannes Kepler. Without performing new experiments, and solely by application of the laws of light refraction, he analyzed the path of light through the eye and demonstrated that an image is formed on the retina and that it is inverted. Acceptance of this discovery was impeded by contemporary prejudices which could imagine nothing but an upright image in the eye, even though this attitude could not explain certain phenomena. Kepler's discovery of the path of light in the eye made it possible to explain the following physical phenomena: central visual acuity, visual field, dark adaptation, and errors of refraction. Physiological diplopia and the mechanism of accommodation were discovered later. The law stating that the intensity of light decreases with the square of distance was also formulated by Johannes Kepler; this law, too, could only be demonstrated after the path of light through the eye had been discovered. In recent years the Keplerian telescope has assumed a practical significance in ophthalmological optics. As a reading aid for individuals with impaired vision it offers a significantly higher magnification than any other optical visual aid. PMID:3520121

    Objective: To report the clinical presentation of malarial retinopathy in an adult, emphasizing the importance of this diagnosis for the clinical suspicion and prognosis of cerebral malaria. Methods: A 39-year-old caucasian man presented with hemolytic anemia, thrombocytopenia, acidemia and acute renal failure, developing severe encephalopathy. The diagnosis of Plasmodium falciparum malaria was done and after systemic stabilization, the patient noticed a central scotoma in the left eye. Ophthalmological examination revealed retinal features of malarial retinopathy. Results: At one-month follow-up, the patient had improved his systemic condition and the left eye scotoma had disappeared. Visual acuity was 20/20 in both eyes and on examination almost all lesions had regressed. Conclusion: Malarial retinopathy is a diagnostic factor and a prognosis indicator of severe P. falciparum infection, usually with brain involvement. The knowledge of the ophthalmological features associated with severe malaria, which is more frequent in children but can also occur in adults, becomes imperative in order to reduce the risk of neurologic sequelae and associated mortality.

    Although the incidence of cancer and cancer related deaths in the United States has decreased over the past two decades due to improvements in early detection and treatment, cancer still is responsible for a quarter of the deaths in this country. There is much room for improvement on the standard treatments currently available and the National Cancer Institute (NCI) has recognized the potential for nanotechnology and nanomaterials in this area. The NCI Alliance for Nanotechnology in Cancer was formed in 2004 to support multidisciplinary researchers in the application of nanotechnology to cancer diagnosis and treatment. The researchers in the Alliance have been productive in generating innovative solutions to some of the central issues of cancer treatment including how to detect tumors earlier, how to target cancer cells specifically, and how to improve the therapeutic index of existing chemotherapies and radiotherapy treatments. Highly creative ideas are being pursued where novelty in nanomaterial development enables new modalities of detection or therapy. This review highlights some of the innovative materials approaches being pursued by researchers funded by the NCI Alliance. Their discoveries to improve the functionality of nanoparticles for medical applications includes the generation of new platforms, improvements in the manufacturing of nanoparticles and determining the underlying reasons for the movement of nanoparticles in the blood.

    Over the past seven years, NASA's Sun-Earth Connection Education Forum has sponsored and coordinated education and public outreach events to highlight NASA's heliophysics research and discoveries. Our strategy involves using celestial events, such as total solar eclipses and the Transit of Venus, as well as Sun-Earth Day during the March Equinox, to engage K-12 schools and the general public in space science activities, demonstrations, and interactions with space scientists. In collaboration with partners that include the Exploratorium and other museums, Ideum, NASA TV, NASA heliophysics missions, and others, we produce webcasts, other multi-media, and print resources for use by school and informal educators nation-wide and internationally. We provide training and professional development to K-12 educators, museum personnel, amateur astronomers, Girl Scout leaders, etc., so they can implement their own outreach programs taking advantage of our resources. A coordinated approach promotes multiple programs occurring each year under a common theme. As part of an Ancient Observatories theme in 2005, we have successfully featured solar alignments with ancient structures made by indigenous cultures that mark the equinoxes and/or solstices in cultural and historical parks in the Americas. In partnership with the Exploratorium, we produced broadcast-quality and webcast programming during the March equinox that shared heliophysics within a broad cultural context with formal and informal education audiences internationally. The program: "Descent of the Serpent" featured the light and shadow effect at sunset that takes place during the spring equinox at the Pyramid of El Castillo, in Chichén Itzá (México). This program made unique and authentic cultural connections to the knowledge of solar astronomy of the Maya, the living Mayan culture of today, and the importance of the Sun across the ages.

    Patients with spina bifida have multiple ophthalmologic problems, many of which are preventable. Most of the problems are related to the hydrocephalus, which is caused by the coexisting Arnold-Chiari malformation. When patients are treated for hydrocephalus, and comprehensive eye care is available, 94% of the patients will have 6/12 visual acuity or better. Strabismus is common but it responds well to medical and surgical treatment. Children with spina bifida should have frequent examinations by an ophthalmologist who is familiar with the diagnosis and management of the defects recorded in this study.

    The ACGME is moving towards the next generation of accreditation in the USA called the Next Accreditation System (NAS). The NAS is anticipated to reduce the burden on programs to comply with accreditation requirements; to produce meaningful, innovative, and continuous benchmark outcomes data; to use ongoing individual and programmatic milestones to judge performance; and ultimately to produce better trained residents, to improve the quality of care, to reduce health care costs and health care disparities, and to provide objective evidence to the public and other external stakeholders of the quality of graduate medical education across the specialties of medicine. We describe the ACGME milestone development process for ophthalmology. If successful, the NAS will benefit all programs by reducing the programmatic burden and paperwork; increasing accreditation cycle length; and improving all programs through formative and summative feedback.

    1997-01-01

    Discoveries of some ancient medical instruments and equipment found in the Hellenic world have been published in magazines of general interest and in a rare Greek medical journal, yet none caught the attention of ophthalmologists. Among these instruments are two forms of the famous 'Kenteterion', dating from the Hellenistic period, used for the couching of cataract. These were found on the island of Milos in the last century. Two magnifying lenses of the Archaic period from the recent Cretan excavations gave us the opportunity to discuss the problem of their medical use. The two drop-bottles from the excavations on Cyprus and at Tanagra, which are also described, seem to be of medical, and possible ophthalmological, use. PMID:9657298

  14. Femtosecond Lasers in Ophthalmology: Surgery and Imaging

    NASA Astrophysics Data System (ADS)

    Bille, J. F.

    Ophthalmology has traditionally been the field with prevalent laser applications in medicine. The human eye is one of the most accessible human organs and its transparency for visible and near-infrared light allows optical techniques for diagnosis and treatment of almost any ocular structure. Laser vision correction (LVC) was introduced in the late 1980s. Today, the procedural ease, success rate, and lack of disturbing side-effects in laser assisted in-situ keratomileusis (LASIK) have made it the most frequently performed refractive surgical procedure (keratomileusis(greek): cornea-flap-cutting). Recently, it has been demonstrated that specific aspects of LVC can take advantage of unique light-matter interaction processes that occur with femtosecond laser pulses.

    Optical aberrations reduce the imaging quality of the human eye. In addition to degrading vision, this limits our ability to illuminate small points of the retina for therapeutic, surgical or diagnostic purposes. When viewing the rear of the eye, aberrations cause structures in the fundus to appear blurred, limiting the resolution of ophthalmoscopes (diagnostic instruments used to image the eye). Adaptive optics, such as deformable mirrors may be used to compensate for aberrations, allowing the eye to work as a diffraction-limited optical element. Unfortunately, this type of correction has not been widely available for ophthalmic applications because of the expense and technical limitations of current deformable mirrors. We present preliminary design and characterisation of a deformable mirror suitable for ophthalmology. In this ferrofluidic mirror, wavefronts are reflected from a fluid whose surface shape is controlled by a magnetic field. Challenges in design are outlined, as are advantages over traditional deformable mirrors.

    Background Visual acuity is the primary measure used in ophthalmology to determine how well a patient can see. Visual acuity for a single eye may be recorded in multiple ways for a single patient visit (eg, Snellen vs. Jäger units vs. font print size), and be recorded for either distance or near vision. Capturing the best documented visual acuity (BDVA) of each eye in an individual patient visit is an important step for making electronic ophthalmology clinical notes useful in research. Objective Currently, there is limited methodology for capturing BDVA in an efficient and accurate manner from electronic health record (EHR) notes. We developed an algorithm to detect BDVA for right and left eyes from defined fields within electronic ophthalmology clinical notes. Methods We designed an algorithm to detect the BDVA from defined fields within 295,218 ophthalmology clinical notes with visual acuity data present. About 5668 unique responses were identified and an algorithm was developed to map all of the unique responses to a structured list of Snellen visual acuities. Results Visual acuity was captured from a total of 295,218 ophthalmology clinical notes during the study dates. The algorithm identified all visual acuities in the defined visual acuity section for each eye and returned a single BDVA for each eye. A clinician chart review of 100 random patient notes showed a 99% accuracy detecting BDVA from these records and 1% observed error. Conclusions Our algorithm successfully captures best documented Snellen distance visual acuity from ophthalmology clinical notes and transforms a variety of inputs into a structured Snellen equivalent list. Our work, to the best of our knowledge, represents the first attempt at capturing visual acuity accurately from large numbers of electronic ophthalmology notes. Use of this algorithm can benefit research groups interested in assessing visual acuity for patient centered outcome. All codes used for this study are currently

    This short paper mentioned the medical treatment using the 'holy' springs, the first 'eye doctor' in Denmark, the first picture of spectacles which was found in Viborg Cathedral of the high priest before he performs circumcisio praeputii on Jesus Christ, further cataract reclination in Denmark from around year zero and cataract extraction in 1667 in Denmark on a goose by Francisco Borri and on humans by the Danish Georg Heuermann in 1755. Epidemic military eye diseases in 1807, 1856 and 1865 are also described in this study. From 1856, a new ophthalmological period started in Denmark with the first eye hospital (lazaret only for eye diseases), and in 1864, patients with eye diseases were transported from the few beds in the surgical departments in the municipal hospital to the first civil eye department in Denmark, the eye hospital Sct. Annae in Copenhagen. The new scientific period started with Jacob Christian Bentz (ophthalmia granulosa, joint editor of the Danish Medical Journal) and Heinrich Lehmann. PMID:26899921

    Objective: To evaluate the nature and incidence of pathological ocular conditions in boxing. Methods: A group of 20 active, elite, amateur, asymptomatic Turkish boxers were examined and compared with a control group composed of 20 age matched sportsmen who were not boxers. The boxers had been actively boxing for 5–20 years (mean 9.65), were aged 16–34 (mean 22.25), and weighed 51–91 kg (mean 73.07). They had been involved in 67–500 fights (mean 143.8), with 5–40 losses (mean 17.75). All were championship title holders at the national, European, Olympic, or World level. Results: An atrophic retinal hole was found in one boxer, which was treated with laser prophylaxis. In this series, the incidence of traumatic eye injuries was much lower than in the literature. Possible reasons are their young age, their division being mainly lightweight or middleweight, few fight losses, being elite boxers, their fighting distance being near or distant, protective methods, and racial factors. Conclusion: Boxing does not appear to be as hazardous to the eyes as previously reported, but prospective, longitudinal studies need to be carried out, including boxers of all divisions, ages, boxing experience, and level, and using various methods of fighting and protection. It should be made mandatory for all boxers to have a complete ophthalmological examination at the beginning of their careers and periodically thereafter. PMID:12453836

    Most ophthalmologic disorders secondary to hypercoagulabe state are due to the confluence of congenital and adquired factors. A systematic workup is mandatory. Most of congenital coagulation disorders cause venous trombosis and are inherited autosomal dominantly. In order of frequency these are factor V Leiden mutation (activated protein C resistance), G20210A mutation of the prothrombin gen and protein C, protein S, and antithrombin III deficiencies. Sickle cell anemia can determine arerial and venous thrombosis. In relation with arterial occlusion, the markers most frequently involved are homcysteine fasting levels and the markers of antiphospholipid antibody syndrome. Both of them can also determine venous thrombosis. Several acquired factors can lead to hypoercoagulable state, especially hyperhomocysteinemia, antiphospholipid antibody syndrome, hepatic disease, alcohol and tobacco intake, oral contraceptives, immobilization, surgeries and malignancies. In central venous occlusion is only necessary to rule out hyperhomocysteinemia and antiphospholipid antibody syndrome in young patients without known risk factors. In central artery occlusion, hypercoagulable workup is only recommended for patients less than 50 years-old with unknown emboli source. In this cases protein C, protein S, and antithrombin III deficiencies, homocystein, sickle cell disease and antiphospholipid antibody syndrome will ruled out. In non arteritic ischemic optic neuropathy hypercoagulable work up is not necessary. In amaurosis fugax without known emboli source, it is recommended to rule out etiologies of arterial occlusion, especially antithrombin III deficiencies, homocystein, sickle cell disease and antiphospholipid antibody syndrome.

    The main characteristics of the laser radiations are: directivity, monochromaticity and spatially and temporally coherence. Using the aggregation state as a criterion for classification, we describe solid, liquid and gaseous active media. Concerning the methods used to realize the population inversion, we also describe: optically, electrically and high energy particles pumped lasers. Depending on the laser media and the mode of excitation, a laser may operate in multiple ways: the continuous-wave operation, the long-pulsed operation, the Q-switched mode of operation and the mode-locked operation. The interaction of laser radiations with the living matter is based upon four main effects: the thermal, mechanical, electrical and biological effect. The main field of therapeutical use of lasers are: the management of lid tumors and intraocular tumors, dacryocystorhinostomy, the treatment of diabetic retinopathy, thromboembolic retinal syndromes, inflammatory choriretinal disease, chorioroetinal degenerations, retinal angimatosis, retinal breaks and retinal detachment, corneal diseases, glaucoma, lens diseases. Laser has also nontherapeutical applications in diagnosis and prognosis of ophthalmologic diseases.

  4. Ultrasonic biomicroscopy in ophthalmology and eye banking

    1999-06-01

    Echography has become a valuable diagnostic tool in ophthalmology. Ultrasonic biomicroscopy (UBM) in particular may be applied to the evaluation of small lesions of the anterior segment of the eye. Disease processes such as conjunctival and iris melanoma, other forms of neoplasia, intraocular cysts, narrow angle glaucoma, and intraocular foreign bodies can be diagnostically evaluated and followed longitudinally by UBM. Combining UBM with spectroscopy may become useful in determining cell type origins of a variety of tumors. Eye banking also has an increased need for UBM in corneal tissue banking. The recent development of the Laser In Situ Keratomileusis procedure has allowed corneal surgeries to create a partial thickness flap of tissue in the cornea, remove tissue from the base of the cornea with excimer laser ablation, and replace the hinged flap. This causes a substantial change in refractive error while thinning the cornea and leaving an interface within the corneal stroma. The ability to detect this type of surgery is essential in eye banking. Ultrasonic pachymetry to determine central thickness and biomicroscopy to detect the presence of an interface are essential in avoiding the use of these corneas for transplantation purposes. Determining the topography of the preserved corneas is another potential application for ultrasonography. Using this information to reduce optical aberration after transplant is crucial in improving visual performance post transplantation. A review of the anatomy of the eye, pathology of ocular diseases relevant to UBM, and principles of eye banking will be presented.

    2016-01-01

    Abstract The process of formation of Marx line is studied in this article. Various theories have been proposed previously, in order to explain the mechanisms which lead to the development of Marx line. These theories are based on the characteristics of stained area and do not pay attention to the behavior of dye solution itself on the surface. The aim of this study is to investigate the latter behavior and introduce a new theory based on it, in order to explain the process of the Marx line formation. This study also introduces “Coffee Ring Effect” and its possible applications in explaining some ophthalmological phenomena. The effect of dye solution's behavior on the beneath surface is adopted in order to propose a novel theory. This new hypothesis is called “Anionic Dye Deposition” which was based on “Coffee Ring Effect” phenomenon. For evaluation of this theory, Evaporation pattern of Rose Bengal and fluorescein were analyzed on different surfaces. Furthermore, the effect of tear meniscus alteration on lid margin staining is studied. During the evaporation process of dye solutions, it was observed that almost all of the solute was deposited at the edge of the drop on hydrophilic surfaces. Furthermore, in the study of lid margin staining, it is observed that tear meniscus alteration during gaze affects staining pattern. This observation invalidates former hypotheses which only focus on stained surface characteristics. According to the observations in this study, it is proposed that Marx line staining occurs as a result of “anionic dye deposition” due to evaporation. PMID:27057835

    Objective Team-based learning (TBL) is an increasingly popular teaching method in medical education. However, TBL hasn’t been well-studied in the ophthalmology clerkship context. This study was to examine the impact of modified TBL in such context and to assess the student evaluations of TBL. Methods Ninety-nine students of an 8-year clinical medicine program from Zhongshan Ophthalmic Centre, Sun Yat-sen University, were randomly divided into four sequential units and assigned to six teams with the same faculty. The one-week ophthalmology clerkship module included traditional lectures, gross anatomy and a TBL module. The effects of the TBL module on student performance were measured by the Individual Readiness Assurance Test (IRAT), the Group Readiness Assurance Test (GRAT), the Group Application Problem (GAP) and final examination scores (FESs). Students’ evaluations of TBL were measured by a 16-item questionnaire. IRAT and GRAT scores were compared using a paired t-test. One-way analysis of variance (ANOVA) and subgroup analysis compared the effects among quartiles that were stratified by the Basic Ophthalmology Levels (BOLs). The BOLs were evaluated before the ophthalmology clerkship. Results In TBL classes, the GRAT scores were significantly higher than the IRAT scores in both the full example and the BOL-stratified groups. It highlighted the advantages of TBL compared to the individual learning. Quartile-stratified ANOVA comparisons showed significant differences at FES scores (P < 0.01). In terms to IRAT, GRAT and GAP scores, there was no significant result. Moreover, IRAT scores only significantly differed between the first and fourth groups. The FES scores of the first three groups are significantly higher than the fourth group. Gender-specific differences were significant in FES but not the IRAT. Overall, 57.65% of student respondents agreed that TBL was helpful. Male students tended to rate TBL higher than female students. Conclusion The application

    2013-01-01

    Background Major academic ophthalmology departments have been expanding by opening multi-office locations (“satellites”). This paper offers a first glimpse into satellites of academic ophthalmology departments. Methods Leaders of seven medium to large, geographically diverse departments agreed to participate. One- to two-hour phone interviews were conducted to assess the features of their satellite practices. Results Success as clinical entities, profitability, and access to patients were stated goals for most satellites. In approximate descending order, refractive surgery, retina, oculoplastics, and pediatric ophthalmology were the most common subspecialties offered. Faculty staffing ranged from recruitment specifically for satellites to rotation of existing faculty. Except for a department with only one academic track, satellite doctors were a mix of tenure and mostly non-tenure track faculty. According to these department leaders, scholarly productivity of satellite faculty was similar to that of colleagues at the main campus, though research was more community-based and clinical in nature. Fellowship but little resident education occurred at satellites. Though it was agreed that satellite practices were integral to department finances, they accounted for a smaller percentage of revenues than of total departmental visits. Conclusions Satellite offices have offered access to a better payor mix and have boosted the finances of academic ophthalmology departments. Challenges include maintaining collegiality with referring community physicians, integrating faculty despite geographic distance, preserving the department’s academic “brand name,” and ensuring consistent standards and operating procedures. Satellite clinics will likely help departments meet some of the challenges of health care reform. PMID:24330741

    In an era of reduced peer-reviewed grant funding, performing academic bone oncology-related research has become increasingly challenging. Over the last 10 years we have held an annual meeting to bring together clinicians, clinician/scientists and basic biomedical researchers interested in the effects of cancer and its treatment on skeletal tissues. In the past these "Bone and the Oncologist New Updates Conference (BONUS)" meetings have served as critical catalyst for initiating productive research collaborations between attendees. The 2015 BONUS meeting format focused on potential key research themes that could form the basis of a coordinated national research strategy to tackle unmet clinical and research needs related to complications associated with cancer metastasis to bone. The three themes planned for discussion were: Is bone metastases-related pain the main issue facing patients? Are there new therapeutic targets for patients with bone metastases? How do we more firmly link basic science with clinical practice? We present a summary of lectures and commentaries from the attendees to serve as an example that other similarly motivated groups can model and share their experiences. It is our hope that these presentations will result in comments, feedback and suggestions from all those researchers interested in this important area. PMID:27335772

    Ophthalmology departments can play a unique role in providing care for at-risk patients. This study analyzed the age, gender, and socioeconomic measures for 267,286 unique African American patients seen at University of Pennsylvania Health System (UPHS). Patients seen by the Ophthalmology Department (n=33,801) were older and more likely to be from impoverished zip codes than those seen by other UPHS specialists. These results hint at several inherent advantages of ophthalmology departments in recruiting older, disadvantaged patients to their clinics. We found that supplementing this advantage with strong patient relationships, involvement of community leaders, and customized outreach efforts was key to overcoming access-to-care issues and to reaching these patients. This provides ophthalmologists with a unique opportunity to capture and refer systemic conditions with ocular manifestations and to possibly reduce disparities such as post-hospitalization readmission and mortality observed disproportionately in impoverished populations.

    Within the frame of the international field campaign COPS (Convective and Orographically-induced Precipitation Study), a large suite of state-of-the-art meteorological instrumentation was operated, partially combined for the first time. The COPS field phase was performed from 01 June - 31 August 2007 in a low-mountain area in southwestern Germany/eastern France covering the Vosges Mountains, the Rhine valley and the Black Forest Mountains. The collected data set covers the entire evolution of convective precipitation events in complex terrain from their initiation, to their development and mature phase up to their decay. 18 Intensive Operation Periods (IOPs) with 34 operation days and 8 additional Special Observation Periods (SOPs) were performed providing a comprehensive data set covering different forcing conditions. In this paper an overview of the COPS scientific strategy, the field phase, and its first accomplishments is given. Some highlights of the campaign are illustrated with several measurement examples. It is demonstrated that COPS provided new insight in key processes leading to convection initiation and to the modification of precipitation by orography, in the improvement of QPF by the assimilation of new observations, and in the performance of ensembles of convection permitting models in complex terrain.

    Sarcopenia and cachexia are significant medical problems with a high disease-related burden in cardiovascular illness. Muscle wasting and weight loss are very frequent particularly in chronic heart failure and they relate to poor prognosis. Although clinically largely underestimated, the fields of cachexia and sarcopenia are of great relevance to cardiologists. In cachexia and sarcopenia a significant number of research publications related to basic science questions of muscle wasting and lipolysis were published between 2010 and 2012. Recently, the two processes of muscle wasting and lipolysis were found to be closely linked. Treatment research in pre-clinical models involves studies on a number of different therapeutic entities, including ghrelin, selective androgen receptor modulators (SARMs), as well as drugs targeting myostatin or melanocortin-4. In the human setting, studies using enobosarm (a SARM) and anamorelin (ghrelin) are in phase III. The last 3 years have seen significant efforts to define the field using consensus statements. In the future, these definitions should also be considered for guidelines and treatment trials in cardiovascular medicine. The current review aims to summarize important information and development in the fields of muscle wasting, sarcopenia and cachexia, focusing on findings in cardiovascular research, in order for cardiologists to have a better understanding of the progress in this still insufficiently known field.

    Avian biology and collection of baseline population data was a major part of the first decade (1951-1961) of field research at the Savannah River Site (SRS). Baseline inventories involving organisms and land-use types were part of the mission in the early contracts between the Atomic Energy Commission (now the Department of Energy) and the University of Georgia prior to the establishment of the Savannah River Ecology Laboratory (SREL) as a National Environmental Research Park Laboratory. About 27% of the SREL publications during this first decade dealt with birds. Since that time, research on the SRS landscape has expanded and broadened with less than 10% of the publications dealing with birds. SRS changed also from an agriculturally dominated area with ca. 40% open areas (fields, crops, pastures) to a timber-managed area with ca. 80% forests, 12% open areas, and 2% open water impoundments. Baseline breeding bird populations of the SRS in the 1950s were typical for the region with avian species richness and density increasing with the age and succession of the vegetation (0-26 species and densities of 0-741 pairs/km2 for the habitats surveyed). During the first decade at the SRS, the resident game bird population of Northern Bobwhites (Colinus virginianus) increased and the Mourning Dove (Zenaida rnacroura) population, a migratory upland game bird, remained stable. Current avian research efforts, as well as new opportunities to reexamine the breeding bird populations and the landscape of SRS, will provide a better understanding of the potential causes of declines of neotropical migratory birds, declines of resident and migratory game birds, and how habitat influences invasions and extinctions of breeding birds in the region. Emphasis for future research and monitoring should be on neotropical migratory bird populations in decline (Yellow-billed Cuckoo, Coccyzus americanus; Eastern Wood-Pewee, Contopus virens; Wood Thrush, Hylocichla mustelina; Prairie Warbler

    Background Egypt has one of the highest prevalence of hepatitis C virus (HCV) worldwide. Ophthalmological side effects are recognized complications of interferon (IFN) therapy. This study aimed to evaluate IFN-induced ophthalmological manifestations in patients receiving PEGylated interferon (PEG IFN) and ribavirin (RBV) and to assess the effect of IFN duration, response and systemic risk factors on the severity. Methods We retrospectively analyzed 100 patients with chronic HCV who were candidates for PEG-IFN and RBV therapy. All patients were subjected to clinical and ophthalmological examination, laboratory investigations, abdominal ultrasound, colored fundus photography and fundus fluorescein angiography, follow up was made at weeks 12, 24, and 48 of treatment. Results IFN-induced retinopathy had been found in (9/100; 9%), 5 (5/9; 55.5%) of them had bilateral lesions, (3/9; 33.3%) were treatment responders and (6/9; 66.6%) non responders. The time of retinopathy appearance was mainly at W12. Retinopathy was asymptomatic in most of the affected patients (7/9; 77.77%) and reversible, cotton wool spots was the major associated sign. Patients with older age, DM and or HTN, and non-responders to antiviral therapy were associated with more severe retinopathy. Conclusions Retinopathy is not a rare complication of IFN therapy for chronic HCV infection, but fortunately it’s asymptomatic and reversible. Ophthalmological assessment at base-line and at follow up during IFN treatment is very important. PMID:27275462

    OBJECTIVE The ophthalmological outcomes of children treated for pineal tumors have received limited attention in the literature. METHODS This paper reviews the outcomes of 29 children treated for pineal and posterior third ventricular tumors in the contemporary era using chemotherapy, radiotherapy, and resection as defined by the histology and/or marker profile of the tumor. RESULTS At the time of diagnosis, all patients except 1 had hydrocephalus and all had ophthalmological involvement. Papilledema was found in 69% of patients. Seventy-five percent of patients had partial or complete Parinaud's syndrome, and diplopia or blurred vision was noted in the remaining patients. Visual acuity was impaired in 8 patients. Outcomes were dependent on the histology of the tumor and the treatment required. Those patients who did not requiring resection showed a lower rate of ophthalmological worsening during treatment and greater long-term improvement, in particular with respect to up-gaze palsy. Patients who underwent resection for postchemotherapy residual disease or primary resection showed greater worsening during treatment and lesser degrees of recovery. All patients with impaired visual acuity improved with treatment. CONCLUSIONS As the mortality of germ cell and other pineal tumors decreases, posttreatment morbidity remains, specifically that related to convergence nystagmus, accommodation, and diplopia. In addition to survival, ophthalmological morbidity should be reported in studies concerning the outcomes of treatment for pineal neoplasms. PMID:26799411

    Purpose To develop a help-wanted index (HWI) to measure trends in marketplace demand for ophthalmologists, to identify the economic drivers of demand, and to determine the impact of economic recessions on the ophthalmology job market. Methods Review of physician recruitment advertisements appearing in the journals Ophthalmology, American Journal of Ophthalmology, and Archives of Ophthalmology from January 1980 through June 2006. Results Over the 26-year study period a consistent increase in the demand for subspecialists (31% of HWI in 1980 to 80% in 2005) was noted. There was also an increase in the demand for academic ophthalmologists. The need for academic ophthalmologists seems to be correlated with national research expenditure and stock market gains (P = .00191), whereas demand for private practice ophthalmologists seems to be correlated with the national economic well-being, as measured by gross domestic product (GDP) (P < .001). Residency applicants (P = .0128) and fellowship applicants (P = .0198) respond to marketplace demand. During the recessions, the demand for ophthalmologists fell 2 to 3 years after the economic downturn. Conclusions Over a 26-year period, HWI data suggest an increased need for subspecialists and academic ophthalmologists. The ophthalmic community has been quick to respond to marketplace demand. National research expenditure, stock market gains, GDP, and discretionary health care expenditure have been associated with the ophthalmology job market. These factors tend to decline with economic recessions. Historically, the demand for ophthalmologists has declined 2 to 3 years following a recession, which may mean lower demand in the near future, given the recent recession. PMID:22253483

    Thirty-one seminars have been held in the 16 years since 1981. A principal interest from the beginning was the genetics of cancer, well before this subject became widely popular. This interest arose in part because of marked binational differences in type-specific cancer rates, such as the very low rates among Japanese for Hodgkin's disease in the young, testicular cancer, Ewing's sarcoma, superficial spreading melanoma, chronic lymphocytic leukemia, and Wilms' tumor (half the U.S. frequency). Three seminars were devoted to the seeming reciprocal relationship between B-cell lymphoma (low in Japan) and certain autoimmune diseases (high in Japan), which is perhaps similar in origin to the male/female differences in the rates for these diseases. A seminar on Li-Fraumeni syndrome led to the recognition of cases among Japanese pedigrees brought to the meeting, and generated a study of its occurrence in Japanese families with adrenocortical carcinoma in a child. Another seminar revealed a marked clustering of rare cancers in Werner's (premature aging) syndrome in Japan, and led to a binational study and analysis of case-reports worldwide. Three seminars on pathology heightened appreciation of the importance of subclassifying cancer by subsite and subtype for racial and other comparisons. Four seminars on biostatistics in cancer research generated a substantial exchange of specialists and trainees in this field. PMID:8613422

  20. Acid Mine Drainage Research in Gauteng Highlighting Impacts on Infrastructure and Innovation of Concrete-Based Remedial Systems

    Acid mine drainage (AMD) is presently one of the most important environmental problems in in the densely populated Gauteng Province, South Africa. The threat of acid mine drainage has demanded short-term interventions (some of which are being implemented by government) but more importantly sustainable long-term innovative solutions. There have been moments of public apprehension with some media reports dubbing the current scenario as a future 'nightmare of biblical proportions' and 'South Africa's own Chernobyl' that could cause dissolving of concrete foundations of buildings and reinforcement steel, leading to collapse of structures. In response to the needs of local and provincial authorities, this research was conducted to (1) generate scientific understanding of the effects of AMD on infrastructure materials and structures, and (2) propose innovative long-term remedial systems based on cementitious materials for potential AMD treatment applications of engineering scale. Two AMD solutions from the goldfields and two others from the coalfields were used to conduct corrosion immersion tests on mild steel, stainless steel, mortars, pastes and concretes. Results show that AMD water from the gold mines is more corrosive than that from the coal mines, the corrosion rate of the former being about twice that of the latter. The functionality of metal components of mild steel can be expected to fail within one month of exposure to the mine water. The investigation has also led to development of a pervious concrete filter system of water-cement ratio = 0.27 and cement content = 360 kg/m3, to be used as a permeable reactive barrier for AMD treatment. Early results show that the system was effective in removing heavy metal contaminants with removal levels of 30% SO4, 99% Fe, 50-83% Mn, 85% Ca, and 30% TDS. Further work is on-going to improve and optimise the system prior to field demonstration studies.

    NREL's new simulator helps speed up research in the race to improve photovoltaic efficiency. Scientists at the National Renewable Energy Laboratory (NREL) needed a quick and accurate method to predict energy generated from multijunction photovoltaic (PV) test devices. This method had to take into account the nonlinear behavior of multijunction PV. NREL achieved this by developing the One-Sun Multi-Source Simulator (OSMSS), which reduces the time for this type of reference spectrum efficiency measurement from hours or days to minutes. The OSMSS is an automated, spectrally adjustable light source that builds a unique simulator spectrum that causes a multijunction PV device to behave as it would under a reference spectrum. This new simulator consists of four light sources separated into nine wavelength bands between 350 and 2,000 nm. The irradiance in each band is adjustable from zero to about 1.5 suns. All bands are recombined via optical fibers and integrating optics to produce a nearly 10 cm x 10 cm uniform spot. The operator simply links the OSMSS to the quantum efficiency data for the test device, and the OSMSS does the rest. The OSMSS can also determine the power as a function of the spectral irradiance (beyond the reference spectra), total irradiance, and temperature. Major components of the system were built to NREL specification by LabSphere, Inc. NREL developed a new, fully automated tool that rapidly builds a spectrum under which all junctions of a multijunction PV device behave as they would under a reference spectrum. Such a spectrum is essential to properly characterize multijunction devices. The OSMSS reduces the time for building spectra for current vs. voltage measurements from hours or days to minutes. This makes it possible to quickly characterize a multijunction device under many different conditions. The OSMSS will be an important tool to help predict the yearly energy output of a multijunction PV device in a particular environment when provided

    Aims Prescribing for athletes requires an up-to-date knowledge of the World Anti-Doping Agency's list of prohibited substances. As the London 2012 Olympic Games attract athletes from around the world, we review the current guidelines with respect to all medications licensed for ophthalmic use in the United Kingdom. We describe the process that an ophthalmologist can use to check for permissible medications and also highlight treatments that are contraindicated. Methods We systematically reviewed all 77 drugs listed in Section 11 of the British National Formulary (Issue 63) for use in the treatment of ophthalmic conditions, and referenced these against the 2012 Prohibited List published by the World Anti-Doping Agency. Results The majority of ophthalmic preparations are suitable for use in- and out-of-competition. Some preparations, such as glucocorticoids, are prohibited when administered systemically but permitted for topical administration. Beta-blockers are prohibited in-competition and oral carbonic anhydrase inhibitors are prohibited in- and out-of competition. Conclusion The 2012 Prohibited List has important implications for the pharmacological treatment of ophthalmic conditions in athletes. Clinicians prescribing for athletes have a duty to familiarise themselves with the list in order to avoid causing significant damage to their patient's career and reputation. PMID:22744394

    High-frequency ultrasound is an attractive means to obtain fine-resolution images of biological tissues for ophthalmologic imaging. To solve the tradeoff between axial resolution and detection depth, existing in the conventional single-pulse excitation, this study develops a new method which uses 13-bit Barker-coded excitation and a mismatched filter for high-frequency ophthalmologic imaging. A novel imaging platform has been designed after trying out various encoding methods. The simulation and experiment result show that the mismatched filter can achieve a much higher out signal main to side lobe which is 9.7 times of the matched one. The coded excitation method has significant advantages over the single-pulse excitation system in terms of a lower MI, a higher resolution, and a deeper detection depth, which improve the quality of ophthalmic tissue imaging. Therefore, this method has great values in scientific application and medical market. PMID:25356093

    272 patients on long-term chloroquine therapy were assessed with respect to ocular toxicity and clinical benefit. A simple scheme for rendering patients ophthalmologically safe is presented, employing the recording of central fields to red targets. Under this it was possible to diagnose a state of premaculopathy, which was reversible on stopping treatment. The incidence of premaculopathy was 41% in 143 patients who otherwise displayed no abnormality of the fundus oculi and who had received a mean total dose of 410 g. of chloroquine phosphate or the hydroxychloroquine sulphate equivalent. Under this joint ophthalmological and rheumatological supervision it was considered that the minor side-effects that may be caused by chloroquine are outweighed by its therapeutic value.

    Background Resident procedure minimums have been established in surgical training programs to ensure adequate training experience. However, achievement of these minimums may fluctuate. Review of resident experience is essential for maintaining successful training curricula. Objective To evaluate trends in ophthalmology resident surgical experience from 2009 to 2015. Methods This was a database study reviewing Accreditation Council for Graduate Medical Education ophthalmology resident surgical case logs. Case logs from 2,797 US ophthalmology residents were reviewed for trends in average surgical cases performed by residents as primary surgeon in the area of cataract, cornea, retina, glaucoma, pediatrics, plastics, and trauma from 2009 to 2015. Results Significant trends in resident surgical experience were demonstrated in the areas of cataract, retina, and glaucoma, while experience in cornea, pediatrics, plastics, and trauma remained stable. These trends included an increase in average cases of phacoemulsification cataract surgery from 143.8 to 173.6, vitreous tap/inject procedures from 31.3 to 93.1, and glaucoma shunt surgery from 4.5 to 6.7, with a decline in average cases of nonphacoemulsification cataract surgery from 3.8 to 2.2, retinal photocoagulation from 59.6 to 45.5, and filtering surgery from 6 to 4.5. Conclusion Trends in ophthalmology surgical experience in cataract, retina, and glaucoma paralleled new surgical or therapeutic developments as well as practice pattern shifts in these fields. Educators should be cognizant of the impact of such trends on resident experience and determine if curricular adjustments should be made to maintain comprehensive education of physicians-in-training.

  9. The human resource crisis in neuro-ophthalmology.

    PubMed

    Frohman, Larry P

    2008-09-01

    Neuro-ophthalmology is facing a serious human resource issue. Few are entering the subspecialty, which is perceived as being poorly compensated compared with other subspecialties of ophthalmology. The low compensation comes from the fact that 1) non-procedural encounters remain undervalued, 2) efforts that benefit other medical specialists are not counted, and 3) the relatively low expenses of neuro-ophthalmologists are not factored into compensation formulas. Mission-based budgeting, which forces academic departments to be financially accountable without the expectation of fiscal relief from medical schools or practice plans, has exacerbated the compensation issue. Solutions must come from within neuro-ophthalmology, academic departments, medical schools, and medical practice plans. They include 1) providing educational resources so that neuro-ophthalmologists need not spend so much time teaching the basics, 2) factoring into compensation the impact of neuro-ophthalmologists in teaching and on revenue generation by procedure-based specialists, 3) improving the efficiency of neuro-ophthalmologists in their consultative practices by providing ample clerical support and other measures, 4) providing contractual salary compensation by departments such as neurosurgery to recognize the contributions made by neuro-ophthalmologists, and 5) reorganizing the academic clinical effort as multidisciplinary rather than departmental.

    Purpose. To arouse ophthalmologists' awareness in patient safety by reviewing sentinel events in Ophthalmology submitted to a web-based incident reporting system involving all public hospitals in Hong Kong. Methods. Sentinel events in Ophthalmology reported from November 2007 to October 2014 were identified and classified into different categories for further presentation and analysis. Key contributing factors attributing to the occurrence of the incidents were described. Suggestions aiming to prevent future occurrence of similar events were made. Relevant literature and case law were discussed. Results. Twelve sentinel events were included in this observational case series. They were classified into 4 main categories, namely “wrong eye” (5 cases, 41%), “wrong prescription” (3 cases, 25%), “wrong patient and surgery” (2 cases, 17%), and “retained surgical items” (2 cases, 17%). The key contributing factor leading to the occurrence of the incidents was largely human error. Increased staff awareness and proper time-out procedures were recommended to help prevent occurrence of these errors. Conclusion. Sentinel events in Ophthalmology do occur. Many of these incidents were attributed to human error. Surgeon's awareness and willingness to prevent occurrence of sentinel events are warranted. PMID:25821586

    In 1979 it was decided to activate, within the Institute of Occupational Health of the Milan "Università degli Studi", a new Unit of Ergophthalmology. This decision was taken owing to the progressive diffusion of "optical instruments", particularly computer-based equipment, in the world of work and to the relevance that this topic assumed among Italian occupational physicians. Since its beginning, one of the main characteristics of the Ergophthalmology Unit was an interdisciplinary approach, where occupational physicians, ophthalmologists, occupational hygienists and lighting engineers were collaborating on a daily basis. Research activities, which developed over many years and in several phases, were concerned with four main topics: 1. analysis and quantification of "near work load"; initially the investigations were mainly aimed at the evaluation of the observation distance in different tasks, followed by the development of a method which, by means of specifically designed electronic equipment, allows quantification of the accommodation and convergence required by the task; 2. development of a new method aimed at evaluating, by a photometric procedure, the luminance ratios in the "occupational visual field"; this research was carried out, both in the laboratory and during on-site investigations, in collaboration with the Dept. of Electrotechnics of Milan Polytechnic; 3. studies on the relationships between indoor microbial pollution and Computer Assisted Design work, considering that ocular conjunctiva and cornea, due to their external position, can be easily inoculated by micro-organisms present on periocular tissue and hands; this research showed that bacteria and fungi pathogenic for the eye (Staphylococcus aureus, Candida sp., Aspergillus sp.) are present on desk, keyboard and mouse, as well as in the conjunctival sac of the exposed operators; 4. studies on "blue light" and its effects on the Pigmented Retinal Epithelium (PRE) in workers exposed to halide

    The advances in gene therapy hold significant promise for the treatment of ophthalmic conditions. Several studies using animal models have been published. Animal models on retinitis pigmentosa, Leber’s Congenital Amaurosis (LCA), and Stargardt disease have involved the use of adeno-associated virus (AAV) to deliver functional genes into mice and canines. Mice models have been used to show that a mutation in cGMP phosphodiesterase that results in retinitis pigmentosa can be corrected using rAAV vectors. Additionally, rAAV vectors have been successfully used to deliver ribozyme into mice with a subsequent improvement in autosomal dominant retinitis pigmentosa. By using dog models, researchers have made progress in studying X-linked retinitis pigmentosa which results from a RPGR gene mutation. Mouse and canine models have also been used in the study of LCA. The widely studied form of LCA is LCA2, resulting from a mutation in the gene RPE65. Mice and canines that were injected with normal copies of RPE65 gene showed signs such as improved retinal pigment epithelium transduction, visual acuity, and functional recovery. Studies on Stargardt disease have shown that mutations in the ABCA4 gene can be corrected with AAV vectors, or nanoparticles. Gene therapy for the treatment of red–green color blindness was successful in squirrel monkeys. Plans are at an advanced stage to begin clinical trials. Researchers have also proved that CD59 can be used with AMD. Gene therapy is also able to treat primary open angle glaucoma (POAG) in animal models, and studies show it is economically viable.

    A one-day workshop on Burkitt lymphoma (BL) was held at the 9th African Organization for Research and Training in Cancer (AORTIC) conference in 2013 in Durban, South Africa. The workshop featured 15 plenary talks by delegates representing 13 institutions that either fund or implement research on BL targeting AORTIC delegates primarily interested in pediatric oncology. The main outcomes of the meeting were improved sharing of knowledge and experience about ongoing epidemiologic BL research, BL treatment in different settings, the role of cancer registries in cancer research, and opportunities for African scientists to publish in scientific journals. The idea of forming a consortium of BL to improve coordination, information sharing, accelerate discovery, dissemination, and translation of knowledge and to build capacity, while reducing redundant efforts was discussed. Here, we summarize the presentations and discussions from the workshop. PMID:25686906

    The growing importance that mobile devices have in daily life has also reached health care and medicine. This is making the paradigm of health care change and the concept of mHealth or mobile health more relevant, whose main essence is the apps. This new reality makes it possible for doctors who are not specialist to have easy access to all the information generated in different corners of the world, making them potential keepers of that knowledge. However, the new daily information exceeds the limits of the human intellect, making Decision Support Systems (DSS) necessary for helping doctors to diagnose diseases and also help them to decide the attitude that has to be taken towards these diagnoses. These could improve the health care in remote areas and developing countries. All of this is even more important in diseases that are more prevalent in primary care and that directly affect the people's quality of life, this is the case in ophthalmological problems where in first patient care a specialist in ophthalmology is not involved. The goal of this paper is to analyse the state of the art of DSS in Ophthalmology. Many of them focused on diseases affecting the eye's posterior pole. For achieving the main purpose of this research work, a literature review and commercial apps analysis will be done. The used databases and systems will be IEEE Xplore, Web of Science (WoS), Scopus, and PubMed. The search is limited to articles published from 2000 until now. Later, different Mobile Decision Support System (MDSS) in Ophthalmology will be analyzed in the virtual stores for Android and iOS. 37 articles were selected according their thematic (posterior pole, anterior pole, Electronic Health Records (EHRs), cloud, data mining, algorithms and structures for DSS, and other) from a total of 600 found in the above cited databases. Very few mobile apps were found in the different stores. It can be concluded that almost all existing mobile apps are focused on the eye's posterior

    Giant cell arteritis with ocular involvement is an ocular emergency. Arteritic anterior ischaemic optic neuropathy (AAION) is the most common ophthalmological manifestation associated with this disease. Visual loss is usually permanent with rare cases showing visual recovery. Visual improvement, if it occurs, is generally limited, and the visual field defects are persistent and severe. The main goal of AAION treatment is the preservation of vision in the fellow eye. In patients with neurophthalmological manifestations, high-dose corticosteroids should be initiated immediately and aggressively, and maintained thereafter. We present a case of AAION and severe vision loss where significant visual recovery was seen after treatment. PMID:26416775

    Most pathological processes involve complex molecular pathways that can only be modified or blocked by a combination of medications. Combination therapy has become a common practice in medicine. In ophthalmology, this approach has been used effectively to treat bacterial, fungal, proliferative/neoplastic, and inflammatory eye diseases and vascular proliferation. Combination therapy also encompasses the synergistic effect of electromagnetic radiation and medications. However, combination therapy can augment inherent complications of individual interventions, therefore vigilance is required. Complications of combination therapy include potential incompatibility among compounds and tissue toxicity. Understanding these effects will assist the ophthalmologist in his decision to maximize the benefits of combination therapy while avoiding an unfavorable outcome. PMID:22454705

    The value of diffusion-weighted magnet resonance imaging (DWI-MRI) has been demonstrated for an ever growing range of clinical indications. DWI is sensitive to the diffusion of water molecules and probes their random displacement within tissue. DWI provides both qualitative and quantitative information on tissue characteristics, e.g. tissue cellularity. This review provides an overview of diffusion-weighted imaging and its emerging applications in ophthalmology. The basic physics and technical foundations of DWI are introduced. The emerging applications of DWI are surveyed, particularly in diseases of the eye, orbit and optical nerve. PMID:26678901

    AIM To evaluate Jordanian ophthalmology residency programs in achieving competencies outlined by the International Council of Ophthalmology (ICO) and residents' satisfaction with available training programs in Jordan, and to highlight weakness points that may be improved and strengthened. METHODS A closed-ended questionnaire was circulated to all ophthalmologists who completed their training in Jordanian institutions between 2006 and 2011, to measure the quality of residency training and satisfaction level with regards to clinical conferences, journal clubs, scientific lectures, wet lab sessions, simulations, outpatient clinics and operating room training. Barriers to a successful board exam were cited. All ophthalmologists had official residency training in Jordanian Hospitals; this includes military, university, governmental and private sector hospitals. RESULTS Sixty-one questionnaires completed out of 69 circulated. Males (75.4%) were more than females. Mean age was 32.5±3.27y. A total 21 (34.4%) responders expressed an overall satisfaction, 38 (62.3%) were dissatisfied and 2 (3.3%) were equivocal. Respondents reported insufficient exposure to low-vision rehabilitation 57 (93.4%), or refraction and glasses prescription 34 (55.7%). Regarding operative experiences, the mean cataract extraction per-resident was 43 cataracts; the number of phacoemulsification surgery was 2.96 per-resident, 46 (75.4%) of responders never did a single phacoemulsification during residency. Nine (14.8%) had training in refractive surgery, and 15 (24.6%) assisted orbital surgery. Forty-four (72.1%) never assisted in vitreoretinal surgery. Among The graduates surveyed, 14 (23.0%) passed Jordanian licensing board exam at the first attempt, and felt that their residency programs adequately prepared them for the examinations. CONCLUSION Around two thirds (62.3%) of ophthalmologists expressed dissatisfaction with residency training at Jordanian programs, further study is required to assess

    Tele-ophthalmology using portable retinal imaging technology, mobile phone and Internet connectivity offers a solution to improve access to diabetic retinopathy (DR) screening services in sub-Saharan African (SSA) countries where the burden of diabetes is increasing and there is limited access to eye care services and specialists. The Zimbabwe Retinopathy Telemedicine Project (ZRTP) established routine DR screening at a hospital-based diabetic clinic in the urban capital city, Harare. A handheld 'point and shoot' digital camera operated by a trained nurse was used to acquire retina images of 203 diabetic patients. A secured 'store-and forward' approach was set up and used for sharing and transfer of images to a retinal specialist at a remote site for reading. This method enabled detection of non-macular DR (11%), diabetic macular oedema (5%), cataract (5%) and glaucoma (6%) among the patients screened. ZRTP demonstrated the utility of tele-ophthalmology for routine retinal screening for diabetic patients in Zimbabwe who have limited access to eye care services. In addition, ZRTP showed how tele-ophthalmology services can provide an empirical framework for providing patient education, and a platform for research in the detection of DR. This approach could be used as a model to address the DR challenges in other countries in SSA. PMID:26407990

    Simulation can be defined as malingering, or sometimes functional visual loss (FVL). It manifests as either simulating an ophthalmic disease (positive simulation), or denial of ophthalmic disease (negative simulation). Conscious behavior and compensation or indemnity claims are prominent features of simulation. Since some authors suggest that this is a manifestation of underlying psychopathology, even conversion is included in this context. In today's world, every ophthalmologist can face with simulation of ophthalmic disease or disorder. In case of simulation suspect, the physician's responsibility is to prove the simulation considering the disease/disorder first, and simulation as an exclusion. In simulation examinations, the physician should be firm and smart to select appropriate test(s) to convince not only the subject, but also the judge in case of indemnity or compensation trials. Almost all ophthalmic sensory and motor functions including visual acuity, visual field, color vision and night vision can be the subject of simulation. Examiner must be skillful in selecting the most appropriate test. Apart from those in the literature, we included all kinds of simulation in ophthalmology. In addition, simulation examination techniques, such as, use of OCT (optical coherence tomography), frequency doubling perimetry (FDP), and modified polarization tests were also included. In this review, we made a thorough literature search, and added our experiences to give the readers up-to-date information on malingering or simulation in ophthalmology. PMID:22553721

    There has been a shift in graduate medical education (GME) from the traditional "apprenticeship" model to a more curriculum-based and competency driven model. Reflecting a global trend towards residency education reform, the International Council of Ophthalmology (ICO) introduced a resident and specialist curriculum and several live educational programs to promote standardization and more effective GME and continuing professional training. Implementation of these educational innovations will require efforts by local educator champions; modification and customization of teaching and assessing tools to the local learning environment; alignment of the implementation blueprint with available resources; and creation of accountability and sustainability mechanisms to insure long-term viability of the educational reforms. An ultimate goal of the ICO curriculum is to allow real world testing and modification so that the ideas generated in one part of the world might be applicable and generalizable in other areas. We aim to describe the Accreditation Council of Graduate Medical Education (ACGME) competencies in the United States (US) and ICO curriculum, as well as to provide a step-by-step plan for implementation of an ophthalmology residency curriculum.

    A stereoscopic imaging modality was developed for the application of ophthalmology surgical microscopes. A previous study has already introduced a single-channel stereoscopic video imaging modality based on a transparent rotating deflector (SSVIM-TRD), in which two different view angles, image disparity, are generated by imaging through a transparent rotating deflector (TRD) mounted on a stepping motor and is placed in a lens system. In this case, the image disparity is a function of the refractive index and the rotation angle of TRD. Real-time single-channel stereoscopic ophthalmology microscope (SSOM) based on the TRD is improved by real-time controlling and programming, imaging speed, and illumination method. Image quality assessments were performed to investigate images quality and stability during the TRD operation. Results presented little significant difference in image quality in terms of stability of structural similarity (SSIM). A subjective analysis was performed with 15 blinded observers to evaluate the depth perception improvement and presented significant improvement in the depth perception capability. Along with all evaluation results, preliminary results of rabbit eye imaging presented that the SSOM could be utilized as an ophthalmic operating microscopes to overcome some of the limitations of conventional ones.

    Purpose Laplace's Law, with its compactness and simplicity, has long been employed in ophthalmology for describing the mechanics of the corneoscleral shell. We questioned the appropriateness of Laplace's Law for computing wall stress in the eye considering the advances in knowledge of ocular biomechanics. Methods In this manuscript we recapitulate the formulation of Laplace's Law, as well as common interpretations and uses in ophthalmology. Using numerical modeling, we study how Laplace's Law cannot account for important characteristics of the eye, such as variations in globe shape and size or tissue thickness, anisotropy, viscoelasticity, or that the eye is a living, dynamic organ. Results We show that accounting for various geometrical and material factors, excluded from Laplace's Law, can alter estimates of corneoscleral wall stress as much as 456% and, therefore, that Laplace's Law is unreliable. Conclusions We conclude by illustrating how computational techniques, such as finite element modeling, can account for the factors mentioned above, and are thus more suitable tools to provide quantitative characterization of corneoscleral biomechanics.

    Visual fields continue to be a key exploration for the diagnosis and follow-up of patients in neuro-ophthalmology. The pattern of visual field defects helps, and in many cases allows, the identification of brain damage location. Manual kinetic perimetry has been replaced by automated methods. 24-2 SITA (Humphrey Visual Field Analyser) and TOP (Octopus) are regarded as the standard perimetric explorations in neuro-ophthalmology. Goldmann perimetry remains as an useful exploration for temporal crescent detection in occipital lobe diseases, and it could be more accurate and consistent for studying lesions in the post-geniculate pathway. Frequency doubling perimetry could be useful for detecting neuro-ophthalmic visual field defects, but does not provide an accurate characterisation of the lesions. From the neuro-ophthalmic point of view, visual field defects could be divided in pre-chiasmatics, chiasmatics and post-chiasmatics. Pre-chiasmatic defects are strictly unilateral, do not respect the vertical meridian, often have a nasal step associated and are usually accompanied by ocular pathology detectable in an ophthalmic examination. The characteristic perimetric pattern of chiasmal disease is bi-temporal hemianopsia. Homonymous contralateral defects are the characteristic perimetric pattern of post-chiasmal disease, and their congruency increases when the lesions are closer to the occipital lobe. Neuroimage studies are mandatory in all patients with a perimetric defect pattern compatible with chiasmal or post-chiasmal lesions. Magnetic Resonance Imaging may be normal in a patient with homonymous defects in Alzheimer's disease, the Heidenhain variant of Creutzfeldt-Jakobs disease, carbon monoxide poisoning and mild occipital ischemia demonstrated by SPECT or PET imaging (Arch Soc Esp Oftalmol 2002; 77: 413-428).

    Carotid cavernous fistulas (CCFs) can be classified as direct and indirect, depending on their flow rates and their etiology. Both forms can cause the same characteristic ophthalmological symptoms and signs. We analyzed these ocular characteristics and determined the prognostics factors associated with treatment outcome. Forty-seven patients with an angiographically confirmed diagnosis of CCF, a preoperative ophthalmic evaluation and at least one ophthalmic sign or symptom at the initial presentation were retrospectively evaluated. The patients were followed-up ophthalmically until the end of treatment, and the complications and the remaining ophthalmological signs and symptoms were then recorded. The patients' ages ranged from 13 to 89 years, with an average of 55.78 (±20.73) years, and a predominance of 28 female (57.8 %) patients. The patients with a direct CCF had a lower average age (p = 0.02). The most common symptoms were blurred vision in 17 (36.2 %) and proptosis in 37 (78.7 %) patients. Elevated intraocular pressure (IOP) was more prevalent in patients with an indirect CCF (p = 0.02). Thrill was more prevalent in patients with direct CCF (p = 0.01). The presence of an initial decrease of visual acuity at the first ophthalmic evaluation was significantly associated with the persistence of ocular symptoms after fistula treatment (odds ratio 3.33). In conclusion our study shows a slight difference in ophthalmic symptoms among patients with different types of fistula. Elevated IOP was significantly associated with indirect fistulas, whereas thrill was significantly associated with direct fistulas. The presence of an initial decrease of visual acuity was significantly associated with a worse ophthalmic prognosis. PMID:22447030

    Purpose: To report the rate of flap-related complications in LASIK surgery performed by in-training ophthalmology residents and to analyze the risk factors for these complications. Methods: We analyzed 273 flap dissections in 145 patients from March 2013 to February 2014. We included all LASIK surgeries performed by 32 ophthalmology residents using a Moria M2 microkeratome. All the flap-related complications were noted. Comparison between both groups with and without complications was performed with an independent Student's t-test and relative risks were calculated. Results: There were 19 flap-related complications out of the 273 flap dissections (6.95%). The most common complication was incomplete flap dissection (n = 10; 3.66%), followed by free-cap (n = 5; 1.83%), and flap-buttonhole (n = 2; 0.73%). There was no significant difference between the complicated and uncomplicated cases in terms of the right versus the left eye, pachymetry results, white-to-white diameter, and spherical equivalent. But this difference was significant for mean keratometry (P = 0.008), K-min (P = 0.01), and K-max (P = 0.03) between these groups. Final visual acuity after rescheduling laser treatment was similar in both groups. Relative risks for flap-related complications were 2.03 for the first LASIK surgery (CI 95% 0.64 to 6.48; P = 0.22) and 1.26 (CI 95% 0.43 to 3.69; P = 0.66) for the surgeon's flap-related complications. Female gender presented an odds ratio of 2.48 (CI 95% 0.68 to 9.00; P = 0.16) for complications. Conclusion: Flap-related complications are common intraoperative event during LASIK surgery performed by in-training ophthalmologists. Keratometries and surgeon's first procedure represent a higher probability for flap related complications than some other biometric parameters of patient's eye.

    In spite of the brief duration of German colonial rule during that period tropical medicine enjoyed a remarkable growth and development. This is the first account of the career of the pioneer of tropical ophthalmology, Alfred Theodor Leber (1881-1954); medical history had previously reported him missing in Java after the 1st world war. His career was greatly influenced by his uncle, Theodor Leber (1840-1917), the founder of experimental ophthalmology. Alfred Leber was the one who combined teaching and research in the subjects of ophthalmology and tropical medicine. During his first expedition as a private lecturer together with von Prowazek in Samoa (1910-1911), he discovered the involvement of the eye in filarial infections with Wuchereria bancrofti (Lebers fundus). In consideration of his extraordinary work he was appointed professor at the young age of 33. After his training at the eye clinic at Berlin University under von Michel he worked as senior physician with von Hippel in Göttingen. Both Ludwig Külz and the famous painter Emil Nolde joined him on his second expedition, to New Guinea, in 1913. During his expedition in summer 1914 World War I broke out. Leber could not return to Germany. He stayed in the neutral Dutch East Indies during these years. Favoured by the ravages of war, British and Australian authorities (Military Intelligence, War Office, Defence) succeeded in seizing some of Leber's research reports and kept them under lock and key. The "Leber-Külz medical demographic New Guinea expedition on behalf of the Reich's Colonial Office" was therefore known to the public only as "Emil Nolde's travels in the South Seas".(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1453664

    2009-01-01

    Background We studied the prerequisites for Public-Private Partnership (PPP) in the context of the Finnish health care system and more specifically in the field of ophthalmology. PPP can be defined as a more or less permanent cooperation between public and private actors, through which the joint products or services are developed and in which the risks, costs and profits are shared. The Finnish eye care services system is heterogeneous with several different providers and can be regarded as sub-optimal in terms of overall resource use. What is more, the public sector is suffering from a shortage of ophthalmologists, which further decreases its possibilities to meet the present needs. As ophthalmology has traditionally been a medical specialty with a substantial private sector involvement in service provision, PPP could be a feasible policy to be used in the field. We thus ask the following research question: Is there, and to what extent, an open window of opportunity for PPP? Methods In addition to the previously published literature, the research data consisted of 17 thematic interviews with public and private experts in the field of ophthalmology. The analysis was conducted in two stages. First, a literature-based content analysis was used to explore the prerequisites for PPP. Second, Kingdon's (1995) multiple streams theory was used to study the opening of the window of opportunity for PPP. Results Public and private parties reported similar problems in the current situation but defined them differently. Also, there is no consensus on policy alternatives. Public opinion seems to be somewhat uncertain as to the attitudes towards private service providers. The analysis thus showed that although there are prerequisites for PPP, the time has not yet come for a Public-Private Partnership. Conclusion Should the window open fully, the emergence of policy entrepreneurs and an opportunity for a win-win situation between public and private organizations are required. PMID

    Andrew Sexton Gray was born in Limerick, Ireland, medically trained in Dublin, and was assistant to William Wilde, the distinguished oculist and aurist. He migrated to Victoria in 1859, was surgeon to a railway's construction company, then in 1862 began practice as a surgeon and oculist in Melbourne. In 1863 he founded a charitable eye and ear hospital, and had a very active, long life devoted mostly to ophthalmology. The hospital progressively expanded and became the centre for training for many ophthalmologists, as well as the nucleus for the cohesion of Victorian ophthalmology. History shows Andrew Sexton Gray to have been a founder of Australian ophthalmology. PMID:3914312

    PurposeHallermann-Streiff-Francois syndrome (HSS) is a rare genetic disorder characterised by ocular and craniofacial anomalies. The purpose of this report is to highlight the ophthalmological features in four such patients and outcomes of cataract surgery.Patients and methodsRetrospective review of medical records of patients with cataract and/or microcornea due to HSS was done. Presenting features, ocular findings, ocular motility and visual outcomes were noted.ResultsWe identified four children with microcornea/cataract who had associated clinical features suggestive of HSS. Mean age at presentation was 25.5±27.8 months. Three children presented with poor vision in both eyes and one with strabismus. All patients had a microcornea and microphthalmos. Three patients had a membranous cataract. Horizontal corneal diameter ranged from 5.5 to 10.5 mm and axial length ranged from 12 to 18 mm. Three patients had associated strabismus. Three patients underwent lens extraction and two underwent strabismus surgery. Best corrected visual acuity (BCVA) improved from fixing, following light to a median post-operative BCVA of 20/380. One eye developed retinal detachment.ConclusionChildren with HSS present with membranous cataracts, microcornea and microphthalmos and present surgical challenges. Though the patients were mostly left aphakic, all showed moderate visual improvement. PMID:27472202

    The Federal Roads Office (FEDRO), Switzerlands federal authority carries responsibility for the action program “Via Sicura” in order to reduce drastically the number of road traffic fatalities and serious injuries on Swiss roads. The revision of the VZV (Verkehrszulassungsverordnung) included in this program will come in to force on 1.July 2016. On that account the legal medical requirements for driver will be renewed. In particular, the requirements for vision (visual acuity, visual field) will be adjusted to international standards. Due to demographic changes the number of elderly drivers with old age (85 – 90+) with eye associated diseases increases. Therefore, questions concerning traffic ophthalmological problems have to be increasingly considered within traffic medical assessments. The driver's vision in traffic's safety must enable him to perceive relevant information, process information quickly and perform an adequate reaction in time, even if visibility is limited (e. g. due to rain, night, darkness) or in the presence of physical or psychical constraints.

    Tolerance analysis by means of simulation is an essential step in system integration. Tolerance analysis allows for predicting the performance of a system setup of real manufactured parts and for an estimation of the yield with respect to evaluation figures, such as performance requirements, systems specification or cost demands. Currently, optical freeform optics is gaining importance in optical systems design. The performance of freeform optics often strongly depends on the manufacturing accuracy of the surfaces. For this reason, a tolerance analysis with respect to the fabrication accuracy is of crucial importance. The characterization of form tolerances caused by the manufacturing process is based on the definition of straightness, flatness, roundness, and cylindricity. In case of freeform components, however, it is often impossible to define a form deviation by means of this standard classification. Hence, prediction of the impact of manufacturing tolerances on the optical performance is not possible by means of a conventional tolerance analysis. To carry out a tolerance analysis of the optical subsystem, including freeform optics, metrology data of the fabricated surfaces have to be integrated into the optical model. The focus of this article is on design for manufacturability of freeform optics with integrated alignment structures and on tolerance analysis of the optical subsystem based on the measured surface data of manufactured optical freeform components with respect to assembly and manufacturing tolerances. This approach will be reported here using an ophthalmological system as an example.

    In this report, protein repelling silicone hydrogels with improved hydrophilicity were prepared by photo-polymerization of silicone-containing monomer and glycidyl methacrylate followed by grafting zwitterionic amino acids. The grafted silicone hydrogels possessed excellent hydrophilic surfaces due to the enrichment of amino acids, which was confirmed by attenuated total reflectance Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, contact angle, and equilibrium water content measurements. Remarkable resistance to bovine serum albumin and lysozyme fouling was observed for the silicone hydrogels immobilized with neutrally charged amino acids because of the formation of zwitterionic surfaces with pairs of protonated secondary ammonium cations and deprotonated carboxyl anions. Meanwhile, the silicone hydrogels grafted with positively or negatively charged amino acids were able to repulse same charged protein with reduced deposition and attract oppositely charged protein with increased adsorption. Preliminary cytotoxicity test indicated that the zwitterionic silicone hydrogels were non-cytotoxic. Similarly, three types of natural amino acids, including serine, aspartic acid and histidine, modified silicone hydrogel contact lenses exhibited excellent hydrophilicity and non-damage to the rabbit's eyes, but only serine modified zwitterionic contact lens showed superior protein fouling resistance compared with the current commercial hydrogel contact lens, which may have great potential application in ophthalmology.

  9. Urologic medications and ophthalmologic side effects: a review

    PubMed Central

    Gani, Johan; Perlis, Nathan; Radomski, Sidney B.

    2012-01-01

    Commonly prescribed urologic medications can have significant ophthalmologic side effects. The existing information can be conflicting. We looked at alpha-blockers and intraoperative floppy iris syndrome (IFIS), phosphodiesterase type 5 (PDE5) inhibitors and non-arteritic ischemic optic neuropathy (NAION) and lastly anticholinergic medications and glaucoma. There is no conclusive scientific data on what to do if the risk of urinary retention is low to moderate, however, we recommend that patients having cataract surgery should stop alpha-blocker medications preoperatively. If there is a high risk of urinary retention, the alpha-blocker should not be withheld, with the active involvement of the ophthalmologist. The role of using 5 alpha-reductase inhibitors (5ARIs) can be considered. There is no convincing evidence that PDE5 inhibitors cause non-arteritic anterior ischemic optic neuropathy (NAION), but patients should be advised of the possible risk of visual loss, especially in patients with risk factors of ischemic heart disease. Acute angle closure glaucoma (AACG or closed angle glaucoma) is very rarely caused by anticholinergic medications in patients with narrow angle anterior eye chambers. However, these medications are safe in patients with open angle glaucoma or treated closed angle glaucoma. Urologists should inquire about the patient’s glaucoma history from his/her ophthalmologist before starting an anticholinergic medication. PMID:22396371

    This paper describes a secure and synthesis ophthalmology telemedicine system, referred to as TeleOph. Under a Secure Socket Layer (SSL) channel, patient prerecorded data can be safely transferred via the Internet. With encrypted videoconference and white-board, the system not only supports hospital-to-clinic consultation, but also supplies hospital-tohospital joint discussion. Based on Directshow technology (Microsoft Corporation, Redmond, WA), video cameras connected to the computer by firewire can be captured and controlled to sample video data. By using TWAIN technology, the system automatically identifies networked still cameras (on fundus and slitlamp devices) and retrieves images. All the images are stored in a selected format (such as JPEG, DICOM, BMP). Besides offline-transferring prerecorded data, the system also supplies online sampling of patient data (real-time capturing from remote places). The system was deployed at Tan Tock Seng Hospital, Singapore and Ang Mo Kio, Singapore, where 100 patients were enrolled in the system for examination. TeleOph can be successfully used for patient consultation, and hospital joint discussion. Meanwhile, TeleOph can supply both offline and online sampling of patient data. PMID:18954255

    Purpose Surgical confusions have been rarely studied, especially in ophthalmology. The author hypothesized that such confusions occur rarely but are unacceptable in the public, legal, and regulatory arenas; often occur in circumstances presenting predictable risk; more often involve wrong lens implant than wrong eye, procedure, or patient; and can be prevented by following the Universal Protocol. Methods A retrospective series of 106 cases occurring between 1982 and 2005 included 42 closed files from the Ophthalmic Mutual Insurance Company and 64 cases reported to the New York State Health Department. Records were grouped by procedure planned and analyzed to answer these questions: How did the error occur? By whom and when was the error recognized? Who was responsible? Was the patient informed? What was done to the patient? What was the outcome? What liability payments were made? What policy changes or sanctions resulted? Was the error preventable by following the Universal Protocol? Results The most common confusion was wrong lens implant, accounting for 67 (63%) of the 106 cases. Wrong eye surgery occurred in 15 cases, wrong eye blocks in 14, wrong patient/procedure in 8, and wrong corneal transplant in 2. In 16 cases, the Universal Protocol would have been unlikely to prevent the confusion. Conclusions Surgical confusions occur infrequently and usually cause little or no permanent injury, but they may be devastating to the patient, the physician, and the profession. Measures to prevent such confusions, including the Universal Protocol and related checklists, deserve the acceptance, support, and active participation of ophthalmologists. PMID:18427628

    Cyclosporine A (CsA) is a cyclic undecapeptide, which is an immunosuppressive drug in the calcineurin inhibitor class. CsA was initially used as a systemic immunosuppressant to minimize rejection of solid organ transplants. In ophthalmology, topically applied CsA was first used to inhibit corneal allograft rejection in the 1980s and later in various inflammatory ocular surface disorders (OSD). Currently, topical ophthalmic CsA is available as a licensed commercial emulsion or is prepared by hospital pharmacies with concentration ranging from 0.05 to 2%. Many of its pharmacological effects on the ocular surface are direct consequences of its ability to inhibit T ciclosporine activation and apoptosis. Topical CsA differs from topical steroids in its favourable local and systemic tolerability at the concentrations used. Most clinical studies have evaluated topical CsA in moderate to severe dry eye disease (DED) and demonstrated its efficacy for improvement of signs and symptoms, thus providing the sole indication for market approval and treatment protocols. For the other indications - corneal graft rejection, blepharitis, allergic or viral keratitis, and ocular surface disease due to graft versus host disease or post-operative DED - evidence-based medicine remains unclear due to the lack of major randomized controlled trials. Despite the lack of standardized protocols or market approval for these conditions, numerous studies suggest clinical efficacy. PMID:26997607

    Optical freeform surfaces are gaining importance in different optical applications. A huge demand arises e.g. in the fields of automotive and medical engineering. Innovative systems often need high-quality and high-volume optics. Injectionmoulded polymer optics represents a cost-efficient solution. However, it has to be ensured that the tight requirements with respect to the system's performance are met by the replicated freeform optics. To reach this goal, it is not sufficient to only characterise the manufactured optics by peak-to-valley or rms data describing a deviation from the nominal surface. Instead, optical performance of the manufactured freeform optics has to be analysed and compared with the performance of the nominal surface. This can be done by integrating the measured surface data of the manufactured freeform optics into the optical simulation model. The feedback of the measured surface data into the model allows for a simulation of the optical performance of the optical subsystem containing the real freeform optics manufactured. Hence, conclusions can be drawn as to whether the specifications with respect to e.g. imaging quality are met by the real manufactured optics. This approach will be presented using an Alvarez-Humphrey optics as an example of a tuneable optics of an ophthalmological application. The focus of this article will be on design for manufacturing the freeform optics, the integration of the measured surface data into the optical simulation model, simulation of the optical performance, and analysis in comparison to the nominal surface.

    The purpose of the study was to evaluate the frequency of ophthalmologic abnormalities in a cohort of myotonic dystrophy type 1 (DM1) patients and to correlate them with motor function. We reviewed the pathophysiology of cataract and low intraocular pressure (IOP). Method Patients were included after clinical and laboratory diagnosis and after signed informed consent. They were evaluated by Motor Function Measure scale, Portuguese version (MFM-P) and ophthalmic protocol. Results We evaluated 42 patients aged 17 to 64 years (mean 40.7 ± 12.5), 22 of which were men. IOP (n = 41) was reduced in all but one. We found cataract or positivity for surgery in 38 (90.48%) and ptosis in 23 (54.76%). These signs but not IOP were significantly correlated with severity of motor dysfunction. Abnormalities in ocular motility and stereopsis were observed. Conclusion Cataract and ptosis are frequent in DM1 and associated to motor dysfunction. Reduced IOP is also common, but appears not to be related with motor impairment. PMID:27050845

    Objective: To review the prevalence of depression in common ophthalmologic disorders in the elderly and provide insight into treatment. Data Sources: PubMed, Google Scholar, and DynaMed were searched using the terms depression and ophthalmology in combination with depression, mood disorders, cataracts, vision loss, age-related macular degeneration, primary open-angle glaucoma, and Fuchs corneal dystrophy. Articles were limited to those published in the English language between 1993 and 2013. Study Selection and Data Extraction: Twenty-eight articles that studied the prevalence of depression in ophthalmologic disorders were screened and summarized. Results: The strongest association between ophthalmologic disorders and psychiatry is depression. In the future, primary care physicians and psychiatrists should play a significant role in the assessment and treatment of depression in visually impaired patients. Conclusion: Greater recognition and treatment of depression in individuals with impaired vision is warranted. PMID:26693037

    Background An important attribute of the traditional impact factor was the controversial 2-year citation window. So far, several scholars have proposed using different citation time windows for evaluating journals. However, there is no confirmation whether a longer citation time window would be better. How did the journal evaluation effects of 3IF, 4IF, and 6IF comparing with 2IF and 5IF? In order to understand these questions, we made a comparative study of impact factors with different citation time windows with the peer-reviewed scores of ophthalmologic journals indexed by Science Citation Index Expanded (SCIE) database. Methods The peer-reviewed scores of 28 ophthalmologic journals were obtained through a self-designed survey questionnaire. Impact factors with different citation time windows (including 2IF, 3IF, 4IF, 5IF, and 6IF) of 28 ophthalmologic journals were computed and compared in accordance with each impact factor’s definition and formula, using the citation analysis function of the Web of Science (WoS) database. An analysis of the correlation between impact factors with different citation time windows and peer-reviewed scores was carried out. Results Although impact factor values with different citation time windows were different, there was a high level of correlation between them when it came to evaluating journals. In the current study, for ophthalmologic journals’ impact factors with different time windows in 2013, 3IF and 4IF seemed the ideal ranges for comparison, when assessed in relation to peer-reviewed scores. In addition, the 3-year and 4-year windows were quite consistent with the cited peak age of documents published by ophthalmologic journals. Research Limitations Our study is based on ophthalmology journals and we only analyze the impact factors with different citation time window in 2013, so it has yet to be ascertained whether other disciplines (especially those with a later cited peak) or other years would follow the same or

    Facial nerve palsy is associated with significant morbidity and can have different etiologies. The most common causes are Bell’s palsy, Ramsay–Hunt syndrome and trauma, including surgical trauma. Incidence varies between 17 and 35 cases per 100,000. Initial evaluation should include accurate clinical history, followed by a comprehensive investigation of the head and neck, including ophthalmological, otological, oral and neurological examination, to exclude secondary causes. Routine laboratory testing and diagnostic imaging is not indicated in patients with new-onset Bell’s palsy, but should be performed in patients with risk factors, atypical cases or in any case without resolution within 4 months. Many factors are involved in determining the appropriate treatment of these patients: the underlying cause, expected duration of nerve dysfunction, anatomical manifestations, severity of symptoms and objective clinical findings. Systemic steroids should be offered to patients with new-onset Bell’s palsy to increase the chance of facial nerve recovery and reduce synkinesis. Ophthalmologists play a pivotal role in the multidisciplinary team involved in the evaluation and rehabilitation of these patients. In the acute phase, the main priority should be to ensure adequate corneal protection. Treatment depends on the degree of nerve lesion and on the risk of the corneal damage based on the amount of lagophthalmos, the quality of Bell’s phenomenon, the presence or absence of corneal sensitivity and the degree of lid retraction. The main therapy is intensive lubrication. Other treatments include: taping the eyelid overnight, botulinum toxin injection, tarsorrhaphy, eyelid weight implants, scleral contact lenses and palpebral spring. Once the cornea is protected, longer term planning for eyelid and facial rehabilitation may take place. Spontaneous complete recovery of Bell’s palsy occurs in up to 70% of cases. Long-term complications include aberrant regeneration

    Cell-based biosensors rely on the detection and identification of single cells as well as monitoring of changes induced by interaction with drugs and/or toxic agents. Raman spectroscopy is a powerful tool to reach this goal, being non-destructive analytical technique, allowing also measurements of samples in aqueous environment. In addition, micro-Raman measurements do not require preliminary sample preparation (as in fluorescence spectroscopy), show a finger-print spectral response, allow a spatial resolution below typical cell sizes, and are relatively fast (few s or even less). All these properties make micro-Raman technique particularly promising for high-throughput on-line analysis integrated in lab-on-a-chip devices. Herein, we demonstrate some applications of Raman analysis in ophthalmology. In particular, we demonstrate that Raman analysis can provide useful information for the therapeutic treatment of keratitis caused by Acanthamoeba Castellanii (A.), an opportunistic protozoan that is widely distributed in the environment and is known to produce blinding keratitis and fatal encephalitis. In particular, by combining Raman analysis with Principal Component Analysis (PCA), we have demonstrated that is possible to distinguish between live and dead cells, enabling, therefore to establish the effectiveness of therapeutic strategies to vanquish the protozoa. As final step, we have analyzed the presence of biochemical differences in the conjunctival epithelial tissues of patients affected by keratitis with respect to healthy people. As a matter of facts, it is possible to speculate some biochemical alterations of the epithelial tissues, rendering more favorable the binding of the protozoan. The epithelial cells were obtained by impression cytology from eyes of both healthy and keratitis-affected individuals. All the samples were analyzed by Raman spectroscopy within a few hours from cells removal from eyes. The results of this analysis are discussed.

    As is now the tradition, the European Southern Observatory looks back at the exciting moments of last year. 2008 was in several aspects an exceptionally good year. Over the year, ESO's telescopes provided data for more than 700 scientific publications in refereed journals, making ESO the most productive ground-based observatory in the world. ESO PR Highlights 2008 ESO PR Photo 01a/09 The image above is a clickable map. These are only some of the press releases issued by ESO in 2008. For a full listing, please go to ESO 2008 page. Austria signed the agreement to join the other 13 ESO member states (ESO 11/08 and 20/08), while the year marked the 10th anniversary of first light for ESO's "perfect science machine", the Very Large Telescope (ESO 16/08 and 17/08). The ALMA project, for which ESO is the European partner, had a major milestone in December, as the observatory was equipped with its first antenna (ESO 49/08). Also the Atacama Pathfinder Experiment (APEX) telescope impressed this year with some very impressive and publicly visible results. Highlights came in many fields: Astronomers for instance used the Very Large Telescope (VLT) to discover and image a probable giant planet long sought around the star Beta Pictoris (ESO 42/08). This is now the eighth extrasolar planet to have been imaged since the VLT imaged the first extrasolar planet in 2004 (three of eight were imaged with VLT). The VLT also enabled three students to confirm the nature of a unique planet (ESO 45/08). This extraordinary find, which turned up during their research project, is a planet about five times as massive as Jupiter. This is the first planet discovered orbiting a fast-rotating hot star. The world's foremost planet-hunting instrument, HARPS, located at ESO's La Silla observatory, scored a new first, finding a system of three super-Earths around a star (ESO 19/08). Based on the complete HARPS sample, astronomers now think that one Sun-like star out of three harbours short orbit, low

    2013-01-01

    Purpose: To evaluate three measures related to electronic health record (EHR) implementation: clinical volume, time requirements, and nature of clinical documentation. Comparison is made to baseline paper documentation. Methods: An academic ophthalmology department implemented an EHR in 2006. A study population was defined of faculty providers who worked the 5 months before and after implementation. Clinical volumes, as well as time length for each patient encounter, were collected from the EHR reporting system. To directly compare time requirements, two faculty providers who utilized both paper and EHR systems completed time-motion logs to record the number of patients, clinic time, and nonclinic time to complete documentation. Faculty providers and databases were queried to identify patient records containing both paper and EHR notes, from which three cases were identified to illustrate representative documentation differences. Results: Twenty-three faculty providers completed 120,490 clinical encounters during a 3-year study period. Compared to baseline clinical volume from 3 months pre-implementation, the post-implementation volume was 88% in quarter 1, 93% in year 1, 97% in year 2, and 97% in year 3. Among all encounters, 75% were completed within 1.7 days after beginning documentation. The mean total time per patient was 6.8 minutes longer with EHR than paper (P<.01). EHR documentation involved greater reliance on textual interpretation of clinical findings, whereas paper notes used more graphical representations, and EHR notes were longer and included automatically generated text. Conclusion: This EHR implementation was associated with increased documentation time, little or no increase in clinical volume, and changes in the nature of ophthalmic documentation. PMID:24167326

    The 10th National Congress of the Italian Association of Nuclear Medicine and Molecular Imaging (AIMN) took place in Rimini on March 18-21, 2011 under the chairmanship of Professor Stefano Fanti. The program was of excellent quality and put a further step for the settlement of the standardized AIMN congress structure. A large industrial exhibition demonstrated the latest technological innovations and developments within the field. The congress was a great success with more than 1100 total participants and more than 360 abstracts received. Of these, 40 abstracts were accepted for oral and 285 for poster presentations. The original investigations presented were related to different areas of nuclear medicine and molecular imaging, with particular focus on advances in instrumentation and data processing, progress in radiochemistry and pharmacy, novel diagnostics and therapeutics, and new insights in well established areas of clinical application, such as oncology, cardiology, neurology, psychiatry, endocrinology, paediatrics, and infection and inflammation. Noteworthy, several presentations at this congress, focusing on quantitative interpretation of the imaging data and on pragmatic endpoints, such as adverse outcomes, identified when nuclear medicine procedures achieved clinical effectiveness for patient care and patient management and further demonstrated that nuclear medicine plays a crucial role in the contemporary medical scenario. This highlights lecture is only a brief summary of the large amount of data presented and discussed, which can be found in much greater detail in the congress abstract book, published as volume 55, supplement 1 of the Q J Nucl Med Mol Imaging in April 2011.

    We evaluated the accuracy of tele-ophthalmology in diagnosing the major causes of chronic blurring of vision. Thirty consecutive patients attending a primary eye-care facility in Singapore (the Ang Mo Kio Polyclinic, AMKP) with the symptom of chronic blurred vision were recruited. An ophthalmic technician was trained to perform Snellen acuity; auto-refraction; intraocular pressure measurement; red-colour perimetry; video recordings of extraocular movement, cover tests and pupillary reactions; and anterior segment and fundus photography. Digital information was transmitted to a tertiary hospital in Singapore (the Tan Tock Seng Hospital) via a tele-ophthalmology system for teleconsultation with an ophthalmologist. The diagnoses were compared with face-to-face consultation by another ophthalmologist at the AMKP. A user experience questionnaire was administered at the end of the consultation. Using face-to-face consultation as the gold standard, tele-ophthalmology achieved 100% sensitivity and specificity in diagnosing media opacity (n = 29), maculopathy (n = 23) and keratopathy (n = 30) of any type; and 100% sensitivity and 92% specificity in diagnosing optic neuropathy of any type (n = 24). The majority of the patients (97%) were satisfied with the tele-ophthalmology workflow and consultation. The tele-ophthalmology system was able to detect causes of chronic blurred vision accurately. It has the potential to deliver high-accuracy diagnostic eye support to remote areas if suitably trained ophthalmic technicians are available. PMID:23520212

    Dias, P L

    1987-07-01

    The knowledge and clinical and minor surgical skills acquired by 257 medical students in three universities in Sri Lanka and Malaysia were assessed by a questionnaire after they had completed their training period in ophthalmology. This study showed that many medical students graduating from these universities lacked the basic clinical and minor surgical skills essential for a doctor practising in a community in south-east Asia. The responses also indicated that teaching by consultants in all three universities was inadequate and due to these inadequacies the students requested that the duration of their training period be doubled. Ophthalmology is an important component of clinical practice and proper education in this subject is important. An urgent revision of the aims and objectives of the curriculum in ophthalmology is essential to place greater emphasis on this important and much neglected subject, for which very little curricular time is allotted.

    2015-08-01

    Idiopathic intracranial hypertension (IIH) is a common neuro-ophthalmologic disorder which leads to significant visual impairment. Clinically, visual manifestation secondary to increased intracranial hypertension generally shows papilledema and the progressive visual impairment subsequently. IIH is a diagnosis of exclusion. The methods include lumber puncture (LP), laboratory tests and imaging examination. However, those methods do limit in evaluation and follow-up in IIH. Currently, with the development of diagnostic technology in ophthalmology, Optical Coherence Tomography and B-scan ultrasound have been employed to estimate intracranial hypertension not only in early diagnosis, but also in long-term follow-up examination. The goal of this review is to sumarize the value of various ophthalmologic methods in evaluation and management of IIH. PMID:26696582

    2003-12-01

    An effort is underway to provide greater visibility within NASA headquarters, and to those who provide funding to NASA, of the outstanding work that is being performed by scientists involved in the Solar System Exploration Research and Analysis Programs, most of whom are DPS members. In support of this effort, a new feature has been developed for the NASA Headquarters Solar System Exploration Division web site whereby researchers can provide a synopsis of their current research results. The site (http://solarsystem.nasa.gov/spotlight/ - Username: your email address Password: sse) is an online submission area where NASA-funded scientists can upload the results of their research. There they provide their contact information, briefly describe their research, and upload any associated images or graphics. The information is available to a limited number of reviewers and writers at JPL. Each month, one researcher's work will be chosen as a science spotlight. After a writer interviews the scientist, a brief Power Point presentation that encapsulates their work will be given to Dr. Colleen Hartman at NASA headquarters. She will then present the exciting findings to Associate Administrator for Space Science, Dr. Ed Weiler. The information from some of these highlights can serve as a basis to bring Principal Investigators to NASA Headquarters for exposure to media through Space Science Updates on NASA television. In addition, the science results may also be incorporated into briefing material for the Office of Management and Budget and congressional staffers. Some spotlights will also be converted into feature stories for the Solar System Exploration website so the public, too, can learn about exciting new research. The site, http://solarsystem.nasa.gov/, is one of NASA's most visited. Over the past decade, there has been a trend of flat budgets for Research and Analysis activities. By giving more visibility to results of Solar System research, our goal is to encourage

    2010-01-01

    In contrast to the recommendations of the International Liga against Epilepsy, many hospitals perform routinely complete ophthalmological examinations in children admitted after a first seizure. As there is no study available to date to prove the benefit of complete eye examinations in first seizure diagnosis, we conducted a study to analyse the value of a complete ophthalmological examination. All children aged 1 month to 18 years who were admitted to the children's university hospital of Leipzig with the clinical diagnosis of a first convulsive or non-convulsive afebrile seizure between 1999 and August 2005 were investigated. All children who had obtained a complete ophthalmological examination within 72 h after the seizure were included in the observational study. A total of 310 children were analysed in the study. Two hundred thirty patients had a tonic-clonic afebrile seizure, the others focal, complex-partial seizures or absences. Two hundred seven out of 310 children showed no ophthalmological pathologies. Eighty-three children had refraction anomalies or strabism, 18 children had optic atrophy, three had congenital eye muscle paresis, and three had malformations. A 16-year-old girl had a homonymous quadrantanopia due to an occipital glioglioma that caused the seizure. An 11-year-old girl had a retinal haemorrhage without any brain lesions after a fall caused by a first tonic-clonic seizure. None of the ophthalmological findings influenced directly the immediate clinical course of diagnosis and treatment of the seizure. Our data suggest that routine ophthalmological examination in all children does not have additional benefit in the first seizure diagnosis management. PMID:19271236

    Since the inception of board certification in ophthalmology in 1916, a written assessment of candidates' knowledge base has been an integral part of the certification process. Although the committee structure and technique for writing examination questions has evolved over the past 100 years, the written qualifying examination remains an essential tool for assessing the competency of physicians entering the workforce. To develop a fair and valid examination, the American Board of Ophthalmology builds examination questions using evidence-based, peer-reviewed literature and adheres to accepted psychometric assessment standards.

    This paper intends to present a Web-based application to collect and manage clinical data and clinical trials together in a unique tool. I-maculaweb is a user-friendly Web-application designed to manage, share, and analyze clinical data from patients affected by degenerative and vascular diseases of the macula. The unique and innovative scientific and technological elements of this project are the integration with individual and population data, relevant for degenerative and vascular diseases of the macula. Clinical records can also be extracted for statistical purposes and used for clinical decision support systems. I-maculaweb is based on an existing multilevel and multiscale data management model, which includes general principles that are suitable for several different clinical domains. The database structure has been specifically built to respect laterality, a key aspect in ophthalmology. Users can add and manage patient records, follow-up visits, treatment, diagnoses, and clinical history. There are two different modalities to extract records: one for the patient’s own center, in which personal details are shown and the other for statistical purposes, where all center’s anonymized data are visible. The Web-platform allows effective management, sharing, and reuse of information within primary care and clinical research. Clear and precise clinical data will improve understanding of real-life management of degenerative and vascular diseases of the macula as well as increasing precise epidemiologic and statistical data. Furthermore, this Web-based application can be easily employed as an electronic clinical research file in clinical studies. PMID:27170913

    The 14th Conference on Retroviruses and Opportunistic Infections generated a lot of excitement with the announcement of clinical studies employing the use of 2 new classes of antiretroviral drugs that target the viral integrase enzyme and the viral coreceptor CCR5. In addition, a number of presentations on cellular restriction factors provided surprises regarding the mechanism by which cellular restrictions antagonize viral infection. There was also much interest in studies presenting novel cellular cofactors of HIV-1 infection. The conference illustrated how basic science research is paying off. Essential steps in the viral life cycle, uncovered through basic research, are now being targeted by new classes of antiviral agents. In addition, basic science is unveiling potential new targets of antiretroviral therapy. PMID:17485783

    Over the last two decades, the scope of our laser research has grown immensely. The small, low-power laser systems of our early days have given way to laser systems of record-breaking size and power. Now we are focusing our activities within the target physics and laser science programs to support the ignition and gain goals of the proposed glass-laser National Ignition Facility. In our laser isotope separation work, we completed the most important set of experiments in the history of the AVLIS Program in 1993, which culminated in a spectacularly successful run that met or exceeded all our objectives. We are also developing lasers and laser-related technologies for a variety of energy, commercial, and defense uses. On the horizon are transfers of important technologies for waste treatment, x-ray lithography, communications and security, optical imaging, and remote sensing, among others.

    Energy means development, and access to energy and electricity should be possible for everyone. The energy challenge for the years to come is to have a sustainable energy supply and after the week spent in Varenna it is clear that "sustainable" cannot be identified with green gas emission reduction only: it has to be an energy supply system respectful of the environment and the humankind, able to provide reliable and affordable energy to the whole world population. This is definitely not an easy challenge: no single energy technology will suffice to safeguard our future and any possible solution has to be exploited at its best, from renewable to nuclear energy, from clean fossil fuels to biofuels. Last but not least, it is the energy efficiency that, given the actual technology, may give the most important and immediate contribution to this challenge. Meanwhile researchers must examine a broad range of options and develop different kinds of technologies: only new investments on R&D can allow to meet the growing demand for energy in a responsible, equitable, and sustainable way.

  3. Highlights of Magnetoelectropolishing

    2014-05-01

    The research work has been concerned on the studies and development of electrochemical polishing in the magnetic field (MEP) in comparison with the standard electropolishing methods performed without stirring (EP) and the process with the forced electrolyte mixing (MIX). Advanced techniques were used in the studies, to measure the effects of the surface treatment. They are as follows: scanning electron microscopy (SEM/EDS), X-ray Photoelectron Spectroscopy (XPS), Secondary Ion Mass Spectroscopy (SIMS), surface roughness, and nanoindentation measurements. For the corrosion studies, the electrochemical methods were used, such as: open circuit potential OCP, potentiodynamic curves PC, and electrochemical impedance spectroscopy EIS measurements. The MEP process is advised mainly due to the opportunity to enrich the surface layer with the chromium compounds (austenitic stainless steels), or titanium compounds (CP Ti Grade 2, Nitinol). The surface layers of biomaterials after MEP process contain much lower amount of carcinogenic compounds, like chromium VI oxidation stage (Cr6+) (austenitic stainless steels) and nickel compounds (austenitic stainless steel & Nitinol) versus those ones obtained after EP & MIX treatments. It is interesting that apart from the significant modification of the surface layer obtained after MEP, also mechanical properties, such as nanohardness, modulus of elasticity, and mechanical resistance to bending and torsion, undergo considerable advantageous changes. All they make the MEP process very promising for application in many clean industries, such as medical equipment and devices, electronics, food industry, etc.

    2012-01-01

    As part of the Fundamental Aeronautics Program and a collaborative effort with Boeing, and Lockheed Martin this past year a series of sonic boom test were completed in the NASA Ames Unitary Plan Wind Tunnel (UPWT). One of the goals was to develop new test techniques and hardware for measuring sonic boom signatures in the transonic and supersonic regimes. Data for various model designs and configurations were collected and will be used to validate CFD predictions of sonic boom signatures. Reactivation of the NASA Ames Mitsubishi compressor system was completed this past year. The compressor is intended to replace and augment the existing UPWT Clark Compressor as the primary Make Up Air (MUA) source. The MUA system provides air and vacuum pumping capability to the Ames UPWT. It will improve productivity and reliability of the UPWT as a vital testing and research facility for the U.S. aerospace industry and NASA. Funding for this task was provided from the American Recovery Investment Act (ARRA). Installation and validation of a Noncontact Stress Monitoring System (NSMS) for the 3-stage compressor was completed at the 11-foot Transonic Wind Tunnel. The system, originally developed at AEDC, consists of 36 pairs of LED light sources with optic beam send and receive probes along a 1-per rev signal. The new system allows for continuous monitoring and recording of compressor blade bending and torsion stress during normal test operations. A very unusual test was completed in the 11 FT TWT to acquire aerodynamic and flow field data for the Crew Exploration Vehicle (CEV) Parachute Assembly System (CPAS) to validate CFD methods and tools. Surface pressure distribution measurements and velocity measurements in the wake of the command module back to the drogues parachute location were acquired. Testing methods included Particle Image Velocimetry (PIV), Pressure Sensitive Paint (PSP), Schlieren Infrared Imaging (IR) and boundary layer survey and skin friction.

    Focal Dermal Hypoplasia (FDH) or Goltz syndrome is a rare multi-system disorder with cutaneous, ocular, dental, and skeletal anomalies due to dysplasia of mesoectodermal derived tissues. It is an X-linked inheritance syndrome caused by mutations in the PORCN gene. This study is aimed to investigate the ocular findings in patients with Goltz syndrome. To date, there have been a limited number of case reports on the ocular manifestations of FDH. This is a prospective, non-consecutive, observational case series. Prospective ophthalmologic evaluation was performed on 18 patients with confirmed genetic testing for FDH, Goltz Syndrome, as a component of a larger multi-subspecialty study to better characterize the findings of this condition. Special attention was placed on evaluating the incidence of anophthalmia, microphthalmia, colobomas (iris, optic nerve, and/or retinal), cataracts, nystagmus, and strabismus. A complete ophthalmologic exam was done on all the patients. The mean patient age was 12.8 years (1-55 years). Eighty-nine percent were female and 77% (14/18) of patients had some form of an ophthalmologic manifestation of the condition. Ophthalmological findings included chorioretinal colobomas (61%), iris colobomas (50%), microphthalmia (44%), anophthalmia (11%), cataracts (11%), and conjunctival and eyelid papillomas (5%). Nystagmus was present in 33% and strabismus in 22% of the patients. Visual acuity ranged from 20/20 to no light perception. This study demonstrates a higher incidence of ophthalmologic manifestations as previously reported (77% vs. 40%). To our knowledge, this is the largest case series reported in the literature with 18 patients. © 2016 Wiley Periodicals, Inc. PMID:27001926

    Vitiligo is a common pigmentary disorder. Many studies across decades and all over the world have attempted to illustrate the pathogenesis behind it; however, the pathogenesis of vitiligo remains elusive. This review article, we present the findings behind the most and updated theories behind this psychologically debilitating and disfiguring disease. The discussion begun with the role of genetic predisposition followed by neural theory first proposed in the 1950s. We highlight the autoimmune hypothesis, followed by the reactive oxygen species model, zinc-α2-glycoprotein deficiency hypothesis, viral theory, intrinsic theory and biochemical, molecular and cellular alterations accounting for loss of functioning melanocytes in vitiligo. Many theories were elaborated to clarify vitiligo pathogenesis. It is a multifactorial disease involving the interplay of several factors. Future research is needed to clarify the interaction of these factors for better understanding of vitiligo pathogenesis and subsequent successful treatment. PMID:25789295

    Thousands of articles have been devoted to examine different types of biosorbents and their use in cleaning polluted waters. An important objective of some studies has been the identification of the biosorption mechanisms. This type of investigation is not always performed, as it can only be done if scientists are aware of all mechanisms that, at least theoretically, control the removal of the target substances. Mistakes are often made, even in highly cited review articles, where biosorption mechanisms are named and/or grouped. The aim of this article is to highlight errors and inaccuracies as well as to discuss different classification systems of the biosorption mechanisms. This article serves as a guide, as well as a platform for discussion among researchers involved in the investigation of biosorbents, in an effort to avoid reproducing errors in subsequent articles.

    Some of the highlights of an experiment designed to study coastal atmospheric phenomena along the California coast (Coastal Waves 1996 experiment) are described. This study was designed to address several problems, including the cross-shore variability and turbulent structure of the marine boundary layer, the influence of the coast on the development of the marine layer and clouds, the ageostrophy of the flow, the dynamics of trapped events, the parameterization of surface fluxes, and the supercriticality of the marine layer.Based in Monterey, California, the National Center for Atmospheric Research (NCAR) C-130 Hercules and the University of North Carolina Piper Seneca obtained a comprehensive set of measurements on the structure of the marine layer. The study focused on the effects of prominent topographic features on the wind. Downstream of capes and points, narrow bands of high winds are frequently encountered. The NCAR-designed Scanning Aerosol Backscatter Lidar (SABL) provided a unique opportunity to connect changes in the depth of the boundary layer with specific features in the dynamics of the flow field.An integral part of the experiment was the use of numerical models as forecast and diagnostic tools. The Naval Research Laboratory's Coupled Ocean Atmosphere Model System (COAMPS) provided high-resolution forecasts of the wind field in the vicinity of capes and points, which aided the deployment of the aircraft. Subsequently, this model and the MIUU (University of Uppsala) numerical model were used to support the analysis of the field data.These are some of the most comprehensive measurements of the topographically forced marine layer that have been collected. SABL proved to be an exceptionally useful tool to resolve the small-scale structure of the boundary layer and, combined with in situ turbulence measurements, provides new insight into the structure of the marine atmosphere. Measurements were made sufficiently far offshore to distinguish between the

    Tumor Necrosis Factor alpha (TNF-α) is a pleiotropic cytokine which plays a primary role in the induction of inflammation in autoimmune diseases. The newest anti-TNF-α agent is adalimumab (Humira, Abbott Pharmaceutical Inc.), a human-derived antibody. This review summarizes the characteristics of adalimumab, highlighting its clinical use in systemic and ocular inflammatory disorders, and the possible therapeutic strategies. Adalimumab has been successfully used for the treatment of rheumatoid arthritis, ankylosing spondylitis, and psoriasis arthritis. More recently, adalimumab has shown promising qualities in controlling intraocular inflammations, even though this has been used prevalently as a rescue therapy for unresponsive cases. This biologic agent was also used in pediatric cases, showing a good safety and efficacy profile. Albeit no direct comparison with other biologics has been done, and adalimumab seems to be equivalent to the other anti-TNF-α, the switching to adalimumab can offer a better uveitic control. Adalimumab is a promising drug for the treatment of uveitis, even though further studies are needed on its application as a primary therapy in uveitis. PMID:21180427

    The sequencing of the human genome has seen the emergence of the direct-to-consumer (DTC) genetic-testing market, which allows individuals to obtain information about their genetic profile and its many health and lifestyle implications. Genetics play an important role in the development of many eye diseases, however, little information is available describing the influence of the DTC industry in ophthalmology. In this review, we examined DTC companies providing genetic test products for eye disease. Of all eye conditions, the majority of DTC companies provided susceptibility testing or risk assessment for age-related macular degeneration (AMD). For the 15 companies noted to offer products, we found considerable variation in the cost, scope and clarity of informational content of DTC genetic testing for ophthalmic conditions. The clinical utility of these tests remains in question, and the American Academy of Ophthalmology recommendations against routine testing for many conditions probably still apply. PMID:25676199

She subsequently developed significant optic disc edema and retinal vascular dilation bilaterally. Patients with similar injuries typically require neurosurgical or vascular intervention. In this case, the patient’s signs resolved spontaneously by 21 months after onset, leaving no residual ocular deficits. PMID:24109248

  1. Ophthalmology's future in the next decade: a historical and comparative perspective.

    PURPOSE: To gain a historical and comparative perspective about the future of ophthalmology within the profession of medicine. METHODS: A literature search is made of disciplines other than medicine (history, sociology, philosophy, economics, and ethics) in order to assess factors responsible for survival and healthiness of a profession. The "learned" professions (medicine, law, and theology) are assessed. Other "professional" careers valued by society (sports and classical music) are reviewed. RESULTS: From the perspective of other disciplines, the future of ophthalmology is seen as vulnerable and fragile. Survival of professions, be they classically or economically defined, is linked to societal needs, a profession's unique commitment and ability to provide services to society, and the profession's maintenance of knowledge as well as skill-based services. Historical evidence has shown erosion of a profession's power consequent to capitalist influences, government influences, access of skills by less trained individuals, and elitist posturing by a profession. Comparative evidence has shown societal acceptance of an escalation of salaries for designated superstars, increasing roles and influence of managerial personnel, and trivialization of values other than economic ones. CONCLUSION: Attention to historical and comparative trends by individual ophthalmologists as well as associations representing ophthalmologists is mandatory if ophthalmology as we know it is to survive within the profession of medicine.

  3. Induced Pluripotent Stem Cells: Development in the Ophthalmologic Field

    PubMed Central

    2016-01-01

    Human induced pluripotent stem cells (iPSCs) are a type of stem cells that can be derived from human somatic cells by introducing certain transcription factors. Induced pluripotent stem cells can divide indefinitely and are able to differentiate into every cell type, which make them viable for transplantation and individual disease modeling. Recently, various ocular cells, including corneal epithelial-like cells, retinal pigment epithelium (RPE) cells displaying functions similar to native RPE, photoreceptors, and retinal ganglion cells, have all been successfully derived from iPSCs. Transplantation of these cells in animal models showed great promise for reversing blindness, and the first clinical trial on humans started in 2013. Despite these promising results, more research is in demand for preventing inadvertent tumor growth, developing precise functionality of the cells, and promoting integration into the host tissue.

    The International Council of Ophthalmology (ICO) is a global organization with a regional focus. Working in partnership with supranational and ICO member societies, the ICO is building a "World Alliance for Sight" to improve access to the highest-quality eye care worldwide. Designed to preserve and restore vision on an international scale, the ICO initiative, "Refocusing Ophthalmic Education," enhances ophthalmic education of residents, subspecialists, medical students, and allied eye care personnel by redefining the most effective ways to teach and in creating beneficial educational opportunities. The "Teaching the Teachers" program helps ophthalmic educators incorporate more effective methods of training and continuing professional development to meet societal needs, achieved in part through regional courses for residency program directors; symposia, and keynote talks presented by ICO's World Ophthalmology Educational Colloquium, Conferences for Ophthalmic Educators, and ophthalmic surgical competency rubrics. Recognizing that standardized curricula are essential for consistent ophthalmic education, the ICO has developed a curricular framework whereby goals, expectations, knowledge base, competencies, and technical training are delineated. The ICO is defining worldwide models of team training and compiling best practice, which will include training-program accreditation to ensure improvement in the education of ophthalmologists. International Council of Ophthalmology Web-based teaching courses, a Webinar Network, and a technology blog further support information and communication technologies for teaching and learning. At the ICO's Center for Ophthalmic Educators (educators.icoph.org), trainers will find valuable teaching resources in multiple languages as well as ways to share ideas and collaborate with peers and other ophthalmic educators.

    The value of the information obtained from Goldmann manual kinetic perimetry beyond 30 degrees was examined. Of 229 randomly selected patients in a University eye clinic who had visual fields performed for reasons other than glaucoma or ocular hypertension only 3 patients had abnormalities confined to the PVF of one or both eyes. In none of these three patients was the PVF necessary to detect disease (Graves' disease, 2 cases; retinoschisis, 1 case). The PVF was useful in determining the localization of the disorder and/or the therapeutic management in 14 patients of whom 4 of these had retinitis pigmentosa and 5 had other disorders where the PVF showed the extent of the retinal damage. For ergo-ophthalmologic purposes the PVF was useful in 45 patients; most frequently because the extent of abnormality provided a basis for warning the patient. In some cases the PVF was considered to be useful for economic disability determination or to exclude significant PVF defects in a patient with only one visually useful eye. In 77 patients the PVF of each eye was abnormal but not of ergo-ophthalmologic significance. If these data can be extrapolated to automated static perimetry, there will be a very great incremental cost for any clinically useful information obtained from the examination of the PVF. Because the cost-effectiveness of the examination must be compared with competing methods of obtaining information, it is proposed that the PVF be examined (1) whenever indicated for ergo-ophthalmologic reasons, or (2) when the CVF examination does not resolve a clinical problem for which there is a reasonably high probability that (a) additional clinically useful information will be obtained by examination of the PVF after the results of the CVF examination have been analyzed, or (b) the eye is likely to have a condition that can be detected or followed best by PVF examination.

    Background Non-attendance for hospital outpatient appointments is a significant problem in many countries. It causes suboptimal use of clinical and administrative staff and financial losses, as well as longer waiting times. The use of Short Message Service (SMS) appointment reminders potentially offers a cost-effective and time-efficient strategy to decrease non-attendance and so improve the efficiency of outpatient healthcare delivery. Methods An SMS text message was sent to patients with scheduled appointments between April and September 2006 in a hospital ophthalmology department in London, reminding them of their appointments. This group acted as the intervention group. Controls were patients with scheduled ophthalmology appointments who did not receive an SMS or any alternative reminder. Results During the period of the study, 11.2% (50/447) of patients who received an SMS appointment reminder were non-attenders, compared to 18.1% (1720/9512) who did not receive an SMS reminder. Non-attendance rates were 38% lower in patients who received an SMS reminder than in patients who did not receive a reminder (RR of non-attendance = 0.62; 95% CI = 0.48 – 0.80). Conclusion The use of SMS reminders for ophthalmology outpatient appointments was associated with a reduction of 38% in the likelihood of patients not attending their appointments, compared to no appointment reminder. The use of SMS reminders may also be more cost-effective than traditional appointment reminders and require less labour. These findings should be confirmed with a more rigorous study design before a wider roll-out. PMID:18513438

    In the ophthalmological field, it is not always easy to adopt a primary prevention. Much more useful would be a secondary prevention program towards the affections at birth or those later developed that, if diagnosed and treated early, grant a normal visual development. Differentiated prevention can be carried out, according to various ages: at the tender age congenital glaucoma and cataract, strabism, ametropia, anisometropia (possible cause of amblyopia) have to be considered; in the adult-senile age must be prevented damages due to hypertension, diabetes, thrombosis, as well as cataract, glaucoma, uveitis, kerato-conjunctivitis and retinal detachment.

Methods The authors conducted a 1-year (October 1, 2013, to September 30, 2014) English-language glaucoma literature search on PubMed of articles containing “glaucoma” or “glaucomatous” with title/abstract as a filter. Medical Subject Headings (MeSH) filtered searching was not performed because of the newness of the reviewed material. Results Literature review yielded 2,314 articles, after which we excluded reviews and letters to the editor. We highlighted articles featuring new or updated approaches to the pathophysiology, diagnosis, or treatment of glaucoma and gave preference to human research. Conclusions This review features literature that is of interest to ophthalmologists in practice and also highlights studies that may provide insight to future developments applicable to clinical ophthalmology.

    Rapid progress in genomics and nanotechnology continue to advance our approach to patient care, from diagnosis and prognosis, to targeting and personalization of therapeutics. However, the clinical application of molecular diagnostics in ophthalmology has been limited even though there have been demonstrations of disease risk and pharmacogenetic associations. There is a high clinical need for therapeutic personalization and dosage optimization in ophthalmology and may be the focus of individualized medicine in this specialty. In several retinal conditions, such as age-related macular degeneration, diabetic macular edema, retinal vein occlusion and pre-threshold retinopathy of prematurity, anti-vascular endothelial growth factor therapeutics have resulted in enhanced outcomes. In glaucoma, recent advances in cytoskeletal agents and prostaglandin molecules that affect outflow and remodel the trabecular meshwork have demonstrated improved intraocular pressure control. Application of recent developments in nanoemulsion and polymeric micelle for targeted delivery and drug release are models of dosage optimization, increasing efficacy and improving outcomes in these major eye diseases.

    1987-06-01

    There is, as yet, no satisfactory theory of stereopsis, despite the fact that our overt knowledge of "solid seeing" is now about 150 years old, and that contributions to our understanding come today from many fields: ophthalmology, psychology, psychophysics, neurophysiology, computer modelling, and optical-TV display technology. We review herein, and demonstrate for the reader whenever possible, certain key perceptual properties of the stereoscopic event of which any general theory must take account: vector stereoscopy and the neural grid, depth in empty visual fields, the relationship between stereoscopic and cognitive contours, stereoscopic contour formation in the presence of blur (thus, at low levels of central visual acuity), the phenomenon of cortical locking and of neural grid evocation in the presence of either peripheral or central rivalry, certain unusual ranges of figural mismatch and the concept of the horopter in relation to modern single cell electroneurophysiology in animals and to the constancy of visual directions. Some comments are also made on the concept of disparity processing by single cortical neurons, together with a short discussion of the implications of certain views of the genetics of stereovision for the perception of novel random texture sine-wave stereograms. We conclude that any theory pertinent to ophthalmology and visual science must combine the global concepts of cortical integration, the neural lock and the neural grid, herein introduced, with the more classical concepts of particulate or local binocular cortical correspondence. Certain preliminary steps in this direction are presented. PMID:3319467

    Two classes of substances which may be used in the treatment of malignant tumors in ophthalmology are studied from the point of view of their spectroscopic properties: synthetic porphyrines such as TNP, TPP, TSPP and Zn-TSPP and cytostatics such as 5-fluorouracil. The absorption, excitation and fluorescence spectra of the porphyrins are measured in water and DMSO solutions to allow their efficient use in photodynamic therapy studies at irradiation with UV-laser light. A spectroscopic study of 5-fluorouracyl, a cytostatic drug used in the treatment of ophthalmologic tumors is reported. Absorption, fluorescence excitation/emission spectra were measured for solutions of 5-fluorouracyl at 5 X 10-5 M concentration. The effects of UV-VIS irradiation of on the 5-fluorouracyl solutions were investigated. The irradiation was performed with a classical Xe lamp having a power density of 11 mW/cm2, at time intervals between 15 min and 60 min. While the absorption is not affected by light irradiation, the fluorescence of the solutions is increasing with the irradiation duration.

    In view of the advancement in drug development and availability of new ocular therapeutics in the discipline of ophthalmology, we attempted to study the drug utilization and describe the prescribing practices of ophthalmologists in a tertiary care teaching hospital. Method. A prospective, cross-sectional, observational study was conducted on patients attending Outpatient Department of Ophthalmology for curative complaints. Prescriptions of 600 patients treated were analyzed by the WHO prescribing indicators and additional indices. Results. Analysis showed that the average number of drugs per prescription was 1.49. Percentage of drugs prescribed by generic name was 2.35%. Percentage of encounters with antibiotics was 44.83%. Percentage of drugs prescribed from National Essential drug list (NEDL)/National Formulary of India (NFI) was 19.48%. Patient's knowledge of correct dosage was 93.83%. Antimicrobial agents were the most commonly prescribed drugs followed by antiallergy drugs and ocular lubricants. Fluoroquinolones accounted for 60% of the total antimicrobial drugs, of which gatifloxacin was the most frequently prescribed fluoroquinolone. Conclusion. The study indicated an awareness of polypharmacy, but showed ample scope for improvement in encouraging the ophthalmologists to prescribe by generic name and selection of essential drugs from NEDL/NFI.

    Sutures are a common way to attach scaffolds in patients. For tubular cardiac scaffolds, the 'suture retention strength' is commonly used to evaluate the resistance of a scaffold against the pull-out of a suture. In order to make this quantity accessible for ophthalmological scaffolds the test procedure has been modified in a novel way. Polycaprolactone (PCL) films of different thicknesses and an amniotic membrane (AM) were used for the experiments. Circular samples with a radius of 7mm were taken and a suture was passed through each sample and tied to a loop. The sample was clamped in a tensile tester and a bolt was passed through the loop. The suture was then pulled with a constant deformation rate until pull-out occurred. The suture retention strength, the deformation at the suture retention strength, and the deformation at rupture were determined for each sample. The presented modified suture retention test allows to measure the relevant parameters of samples on the scale of ophthalmological scaffolds in a reproducible way. A comparison between the first data on PCL and AM has been made. PMID:27612789

    In this report, we present the results of a single patient with optic neuropathy treated within the Stem Cell Ophthalmology Treatment Study (SCOTS). SCOTS is an Institutional Review Board approved clinical trial and is the largest ophthalmology stem cell study registered at the National Institutes of Health to date- www.clinicaltrials.gov Identifier NCT 01920867. SCOTS utilizes autologous bone marrow-derived stem cells in the treatment of optic nerve and retinal diseases. Pre- and post-treatment comprehensive eye exams were independently performed at the Wilmer Eye Institute at the Johns Hopkins Hospital, USA. A 27 year old female patient had lost vision approximately 5 years prior to enrollment in SCOTS. Pre-treatment best-corrected visual acuity at the Wilmer Eye Institute was 20/800 Right Eye (OD) and 20/4,000 Left Eye (OS). Four months following treatment in SCOTS, the central visual acuity had improved to 20/100 OD and 20/40 OS. PMID:26199618

    The current resident selection process for ophthalmology has undergone little change over the last several years and remains highly dependent on the traditional selection factors (i.e., grades, honors, letters of recommendation, and an interview). Unfortunately, these selection factors have not been shown to be consistently predictive of future resident performance. In addition, the Accreditation Council for Graduate Medical Education (ACGME) has mandated implementation of six new competencies in resident training in the USA and the current selection process does not directly recruit for these competencies. We propose an implementation strategy to re-engineer and improve the resident selection process in ophthalmology and potentially develop assessments that would be predictive of actual downstream resident performance that would encompass the ACGME related competencies. An intra-departmental Task Force for the ACGME Competencies reviewed a PubMed literature search regarding resident selection. A content expert (AGL) gleaned selected "good practices" from the literature review and summarized the results. Specific recommendations were reviewed for topicality to ophthalmology and where possible for feasibility, reliability, and validity. We summarize several good practices identified from the literature review and propose an implementation matrix for aligning the resident application process with the ACGME competencies that might include: using a standardized and consolidated academic score for the cognitive domains; converting the letter of recommendation format into a letter of evaluation; standardizing the letters of evaluation, including the "Dean's letter"; using behavior specific interview techniques with standardized questions; and developing a specialty based consensus for the selection of traits specific to ophthalmology that might predict success. The resident selection process for ophthalmology might be improved by implementation of specific good practices

Many scientific discoveries were made possible with ESO's telescopes. Arguably, the most important is the discovery of the first Earth-like planet in the habitable zone of a low-mass red dwarf (ESO 22/07). If there is water on this planet, then it should be liquid!

    The objectives of the African Organisation for Research and Training in Cancer (AORTIC), both at its inception in the early 1980s, and at its reactivation in 2000 following a decade of inactivity, included bringing the products of decades of advances in cancer research to African populations through international collaboration. The historical perspective provided in this report illustrates progress in achieving these objectives through successive continent-wide activities over a period of 30 years, culminating in the organisation's most recent conference held in Durban, South Africa, 21-24 November 2013. The constant growth in the number of attendants and increasing diversity of the nations of their origin are consistent with advances, whereby the number of participants and the nations of their origin have grown from 24 in 1983 to almost 1000 in 2013, and from 14 to 70, respectively. While earlier AORTIC conferences used to assume the atmosphere of 'jamborees', more recent ones have morphed to problem-solving events, with the concerted collaboration of international organisations, including the World Health Organisation (WHO), International Union Against Cancer (UICC), the Africa Union (AU), the US National Cancer Institute (NCI), the International Psycho-Oncology Society (IPOS), and others. The topics of discussion at the Ninth AORTIC International Conference on Cancer in Africa in Durban were those of paramount importance for low- and middle-income countries: childhood cancers, cancers of the cervix, breast, and prostate, as well as cancer care challenges resulting from ignorance, neglect, and economic deprivation. The role of environmental factors that underlie Burkitt's lymphoma was the subject of the Epidemiology of Burkitt Lymphoma in East-African Children and Minors Workshop, highlighting the NCI research programme in East Africa, while the Workshop on Cost Effectiveness of Treatment of Cancer in Africa surmised that treating childhood cancers is affordable

While earlier AORTIC conferences used to assume the atmosphere of ‘jamborees’, more recent ones have morphed to problem-solving events, with the concerted collaboration of international organisations, including the World Health Organisation (WHO), International Union Against Cancer (UICC), the Africa Union (AU), the US National Cancer Institute (NCI), the International Psycho-Oncology Society (IPOS), and others. The topics of discussion at the Ninth AORTIC International Conference on Cancer in Africa in Durban were those of paramount importance for low- and middle-income countries: childhood cancers, cancers of the cervix, breast, and prostate, as well as cancer care challenges resulting from ignorance, neglect, and economic deprivation. The role of environmental factors that underlie Burkitt’s lymphoma was the subject of the Epidemiology of Burkitt Lymphoma in East-African Children and Minors Workshop, highlighting the NCI research programme in East Africa, while the Workshop on Cost Effectiveness of Treatment of Cancer in Africa surmised that treating childhood cancers is

    Among the many astronomical highlights of 2003, the Transit of Mercury certainly attracted great attention as shown by the record number of hits the ESO web page received on that day. But this was a mere rehearsal of an even bigger event we will enjoy in 2004: the Venus Transit. ESO, in partnership with several institutions, is organising a major educational event in connection with it. During 2003, the ESO Educational Office was also involved in various other programmes. They included the web-based "Catch a Star!" and the "Physics and Life" projects, organised with EC sponsorship in connection with the 2003 European Science and Technology Week. The ALMA project, an European-North American collaboration to build an array of 64 12-m submillimetre antennas, moved forward with the signature of the agreement between ESO and the NSF and with the Ground-breaking at Chajnantor. Conceptual studies of a 100-m optical/infrared telescope (OWL) also proceeded well. Several new instruments were installed at ESO telescopes, e.g. HARPS . And the VLT Interferometer (VLTI) received a powerful Adaptive Optics System and made the first detection through infrared interferometry of an extragalactic object. A rapidly increasing number of new scientific results were obtained on the basis of data from ESO telescopes, some of which were highlighted in ESO Press Releases. A number of beautiful images were published. Many of these developments are described in ESO's Press Releases, most with Press Photos, cf. the 2003 PR Index. Some of last year's ESO PR highlights may be accessed directly via the clickable image above.

    Summary Mechanistic studies over the past decades using in vitro systems, animal models, and human tissues have highlighted the complexity of pathophysiological processes of atherosclerosis. Hypercholesterolemia, as one of the major risk factors for the development and progression of atherosclerosis, is still the focus of many mechanistic studies and the major therapeutic target of atherosclerosis. Although there is a dire need to validate many experimental findings in humans, there is a large number of approaches that have been showing promise for contributing to future therapeutic strategies.

    This article traces early career of Kong Pyung Woo, a public figure famous for being the first doctor of medicine in ophthalmology with Korean ethnicity in 1936, for founding and running the oldest and still the most successful private eye clinic in Korea since 1937, and also for his engagement in development of Korean mechanical typewriter since 1949. His case is an illustrative example of how a Korean under the Japanese colonial rule (1910-1945) could build up a career to become a medical doctor, taking full advantage of the chances available. Kong, born in 1907 in a rural province in northwestern Korea, acquired a doctor's license in 1926 by passing the qualifying examination of the Government General in Korea. The qualification test was in itself an outcome of colonial education system, in which the supply of medical doctors by only a few tertiary schools could not meet the demands. After working for a state hospital for one year, Kong volunteered to be a visiting student at Keijo Medical College, to fulfill his dream of "becoming a prominent bacteriologist like Noguchi Hideyo." He was soon officially appointed as a tutor at Department of Ophthalmology, as he had been endorsed by professor Satake Shyuichi for his diligence and earnestness. Satake also encouraged Kong to pursue a doctoral degree and recommended him to Tokumitsu Yoshitomi, a professor in the Department of Pathology at Keijo Imperial University, so that Kong could experience cutting-edge research at the imperial university. Kong reported on his experiments on the pathology of chorioretinitis centralis by 1935. He submitted the reports to Nagoya Imperial University, Japan, as a doctoral thesis, and eventually obtained the degree in 1936, which was the first Korean doctor of medicine in ophthalmology. The doctorate made Kong a public figure and he opened his own private clinic in 1937. The Kong Eye Clinic was the first private eye clinic owned and run by Korean, and soon became popular in Seoul

    The Cluster mission has been operated successfully for 14 years. As the first science mission comprising four identical spacecraft, Cluster has faced many challenges during its lifetime: its long selection process together with SOHO, the failure of the first Ariane V launch, its fast rebuilt, and the launch on two Soyuz rockets in 2000. The separation of the Cluster spacecraft was changed more than 25 times from a few kilometers up to 36000 km to address the various scientific objectives; the smallest distance achieved between two Cluster spacecraft was 4 km, about 50 times smaller than planned at the beginning of the mission. The main goal of the Cluster mission is to study in three dimensions small-scale plasma structures in key plasma regions of Earth’s geospace environment: solar wind and bow shock, magnetopause, polar cusps, magnetotail, plasmasphere and auroral zone. We will present science highlights obtained such as ripples on the bow shock, 3D current measurements and Kelvin-Helmholtz waves at the magnetopause, bifurcated current sheet in the magnetotail, and first measurement of the electron pressure tensor near a site of magnetic reconnection. In addition, we highlight Cluster results on understanding the impact of Coronal Mass Ejections (CME) on the Earth's environment. We will also present the distribution of data through the Cluster Science Data System (CSDS), and the Cluster Archive. Those systems were implemented to provide, for the first time for a plasma physics mission, a permanent and public archive of all the high resolution data from all instruments.

    Susac syndrome is an endotheliopathy affecting the arterioles of the brain, retina, and inner ear. Many cases of Susac syndrome are underdiagnosed, mainly at the early stages of the disease, while prompt diagnosis enables a speedy recovery. Immediate treatment can halt disease progression and even prevent future disability. We report a case of Susac syndrome, describe the difficulties in the diagnosis of this case, and include a detailed history of a 35-year-old man via the presentation of extensive laboratory work-up and imaging studies. Audiometry showed sensorineural hearing loss of about 75 dB in the left ear. Ovoid lesions of the corpus callosum in magnetic resonance (MR) were present as were advanced binocular ophthalmological changes in fluorescent angiography. Methylprednisolone with acetylsalicylic acid and intravenous immunoglobulin (IVIG) were implemented with a positive outcome (clinical and audiometric improvement). PMID:27460737

    Purpose Our aim was to correlate the overall patient volume and the incidence of several ophthalmological diseases in our emergency department with weather data. Patients and methods For data analysis, we used our clinical data warehouse and weather data. We investigated the weekly overall patient volume and the average weekly incidence of all encoded diagnoses of “conjunctivitis”, “foreign body”, “acute iridocyclitis”, and “corneal abrasion”. A Spearman’s correlation was performed to link these data with the weekly average sunshine duration, temperature, and wind speed. Results We noticed increased patient volume in correlation with increasing sunshine duration and higher temperature. Moreover, we found a positive correlation between the weekly incidences of conjunctivitis and of foreign body and weather data. Conclusion The results of this data analysis reveal the possible influence of external conditions on the health of a population and can be used for weather-dependent resource allocation.

    Medical digital imaging has become a key element of modern health care procedures. It provides visual documentation and a permanent record for the patients, and most important the ability to extract information about many diseases. Modern ophthalmology thrives and develops on the advances in digital imaging and computing power. In this work we present an overview of recent image processing techniques proposed by the authors in the area of digital eye fundus photography. Our applications range from retinal image quality assessment to image restoration via blind deconvolution and visualization of structural changes in time between patient visits. All proposed within a framework for improving and assisting the medical practice and the forthcoming scenario of the information chain in telemedicine.

    A 27-year-old male patient was presented with foreign body sensation in both the eyes for 2 years duration and blisters followed by scarring and pigmentation in the photo-exposed areas of the body over the previous 12 years. His urine was reddish colored for the previous year. On examination, there was scarring, hyper-pigmentation of photo-exposed parts of the body along with resorption of the distal phalanges of fingers in both hands except the smallest digit which had onycholysis. Ocular examination indicated scleral necrosis in the interpalpebral areas in both eyes and bilateral dry eye. Hematological examination indicated a picture suggestive of hemolytic anemia. Abdominal ultrasonography indicated an enlarged spleen. These clinical features are suggestive of puberty onset congenital erythropoietic porphyria with ophthalmological manifestations.

    Studies in the central nervous system (CNS) and retina have revealed the significance of docosahexaenoic acid (DHA), an essential omega-3, 22 carbon 6 double bond (22:6), fatty acid. DHA is necessary for various functions in the CNS, including neuronal membrane bio- and synaptogenesis in memory and vision, and it is the precursor for docosanoids and neuroprotectin D1 (NPD1; 10R,17S-dihydroxy-docosa-4Z,7Z,11E,13E,15Z,19Z hexaenoic acid), a DHA bio-derivative with neuroprotective properties. This review covers three targets in ophthalmology for mediator lipidomics, a subgroup within the field of metabolomics: inflammation, neuroprotection and nerve regeneration. It also discusses the role DHA, NPD1 and other lipid mediators play in these three areas. PMID:23981028

    Theoretical investigations and the results of computer modeling of the optical, thermophysical, and thermochemical processes during laser interaction with ocular tissues are reviewed in this paper. Physical-mathematical models and results of numerical simulation of the processes are presented. The computer modeling was applied for investigations of laser heating and coagulation of ocular tissues for treatment of retina diseases and intraocular tumors, cyclophotocoagulation of the ciliary body for treatment of glaucoma, and laser thermal keratoplasty of the cornea. The influence of radiation parameters on the selectivity of laser coagulation of laminated ocular tissues is considered. The results obtained are of essential interest for laser applications in ophthalmology and can be used for investigation of heating and coagulation of tissues in different fields of laser medicine.

    2002-08-01

    For all in-patients a fundamental change of hospital financing based only on diagnosis related groups (DRGs) is planned in Germany for 2004. Patients are grouped into different DRGs according to their coded diagnoses, operations and procedures. Hence, the quality of coding is essential for adequate reimbursement of cases and thus for hospital financing. The legal framework of coding is supplied by the so-called "general and special coding guidelines for coding diseases and procedures", presented jointly by the associations representing hospitals and public and private health insurance companies in early 2002. These German coding standards regulate how coding must be performed in daily practice and therefore have a major influence on the grouping of patients into DRGs. Because of their importance this paper describes the practical application of current coding standards. Specifically in Ophthalmology the problem exists that for many procedures adequate coding numbers are still missing, thus impairing further development of the DRG system. PMID:12353175

    PurposeTo ascertain ophthalmology trainee confidence in managing posterior capsule rupture (PCR) and vitreous loss.MethodsAn electronic survey was distributed to ophthalmology trainees in a single UK postgraduate training Deanery. Data collected included the stage of training, number of completed cataract operations, cumulative PCR rate, number of PCRs personally managed by the trainee, previous vitrectomy experience during vitreoretinal rotations, and attendance at advanced phacoemulsification courses. Trainees self-evaluated their confidence in managing PCR with vitreous loss, including the management of specific aspects of the procedure.ResultsAcross training grades, only 9.1% (2/22) felt confident managing PCR without senior support. Respondents were most confident with fluidic parameters and IOL considerations, but 77.3% (17/22) lacked confidence in avoiding a dropped nucleus. Eleven respondents had completed >350 cases (mean 576; range 383-1087). In this subgroup, mean cumulative PCR rate was 2.1% (range 0.9-4.9%), and trainees personally managed a mean 3.5 cases of PCR (range 1-7). Only 18.2% felt they could manage PCR and vitreous loss without senior support, and 45.5% stated they were not confident in avoiding a dropped nucleus. The most experienced trainee (1087 cases) had personally managed PCR just six times, and three trainees with >350 cases had only managed PCR once each.ConclusionsThe Royal College of Ophthalmologists' requirement of 350 completed cases appears insufficient for independent cataract surgery, as opportunities to manage complications as a trainee are scarce. A competency-based assessment framework may be preferable, with a more targeted approach to training incorporating surgical simulation within the formal curriculum. PMID:27080483

    OJECTIVE This study seeks to identify practices of self-medication in the treatment of ocular emergencies. We examine patients’ use of both homemade preparations and manufactured products before seeking specialized care. MATERIALS AND METHODS We conducted a cross-sectional analytic survey of consecutive patients seen in the ophthalmology emergency room of a teaching hospital. RESULTS The sample included 561 subjects, 51.3% males and 48.7% females, with a mean age of 39.8 years. Prior to seeking emergency care, 40.5% reported self-medicating; 29.4% used a homemade preparation (13.9% referred to an industrialized product like boric acid as a homemade preparation), and 11.1% used a manufactured product. The most frequently used products included a boric acid solution (53.3%), a normal saline solution (35.7%), herbal infusions (6.1%) and breast milk (4.8%). Viral conjunctivitis was the most frequent diagnosis (24.4%), followed by the presence of a corneal foreign body (7.4%). No significant differences were found in the self-treatment of ocular injuries according to gender (p = 0.95), level of education (p = 0.21) or age (p = 0.14). In addition, self-medication practices were not related to the medically judged severity of the condition. CONCLUSION Patients often attempt to treat conditions that require ophthalmologic emergency care by self-medicating with homemade or manufactured products. The most widely used products include boric acid, normal saline, leaf infusions and breast milk. This behavior occurs independently of educational level, gender, age or the nature of the ocular condition. Self-medication is a culturally driven practice that is used even in cases of acute ocular injuries. PMID:19690656

    Purpose A review of retinopathy of prematurity (ROP) malpractice cases will identify specific, repetitive problems in the provision of care and the reasons underlying these problems. Opportunities to improve the quality of care provided to premature infants with ROP will result. Methods A retrospective review of a series of 13 ROP malpractice cases in which the author served as a paid consultant, as well as a review of the literature for additional cases, was conducted. The series of 13 involved a review of the entire medical record as well as testimony and depositions. The characteristics of each case are tabulated, including state, date, allegations, defendants, disposition, award, the medical facts and care issues involved, and the judgment of medical error. In addition, a merit review was performed on the care in each case, and an error assessment was performed. Results The quality of care issues included neonatology failure to refer or follow up in 8 of 13, failure to adequately supervise resident care in 2 of 13, ophthalmologic failure to follow up in 6 of 13, and failure to properly diagnose and manage in 9 of 13. The latter included 4 of 13 that hinged on zone III issues and the presence or absence of full nasal vascularization with or without previous zone II disease. Merit review found negligent error by at least one party in 12 of 13. Ophthalmology error was found in 6 of 13. Malpractice, ie, negligent error causing negligent harm, was judged to be present in 9 of 13. Conclusions Negligent errors are common in malpractice cases that proceed to disposition. There are a limited number of repetitive errors that produce malpractice. An explanation of how these errors occur, coupled with the pertinent pathophysiology, afford an excellent opportunity to improve patient care PMID:18427626

    Introduction: Prolactinomas are less frequent, but more invasive in males. Giant ones (≥4 cm) are extremely rare in literature. Their neurological, psychiatric and endocrine complications are life threatening. Our aim was to report the largest mono center series in order to analyze their frequency, their characteristics, and their complications. Subjects and Methods: All patients had clinical examination, hormonal, ophthalmological, and radiological assessment based on computed tomography scan and cerebral magnetic resonance imaging. Positive diagnosis was based on clinical symptoms, high prolactin ± immunohistochemy study. Mixed adenomas were excluded by hormonal exploration and immunohistochemy. For those who received medical treatment only, a reduction in tumor size was considered a supplementary positive point for the diagnosis. Results: Among 154 male prolactinomas seen between 1987 and 2013, we observed 44 giant tumors (28.5%). Median age = 36 years, and 38.3% were under 30. Median tumor height = 53.95 mm (40–130) and median prolactin = 15,715 ng/ml (n < 20). Solid and cystic aspect ± calcifications was observed in 25%. 42 had cavernous sinuses invasion. Other invasions were: Posterior= 65.9%, anterior= 63.6%, temporal= 15.9% and frontal = 9%. For endocrine complications: Hypogonadism = 98.4%, thyrotroph and corticotroph deficits were seen in respectively 34%, and 32%. Posterior pituitary insufficiency was observed in one case. For ophthalmological complications: Optic atrophy = 46%, Ptosis = 6.8%, diplopia/strabismus = 4.5%. Neurological complications were: Memory loss and/or unconsciousness = 18.2%, epilepsy = 15.9%, frontal syndrome = 9% and obstructive hydrocephalus = 6.8%. Conclusion: Giant prolactinomas account for 28% in our population. Severe neurological complications are frequent. But, obstructive hydrocephalus is rare, which argues for a slow progression.

    OBJECTIVE To determine tear film concentrations of doxycycline in ophthalmologically normal dogs following oral doxycycline administration. DESIGN Crossover study. ANIMALS 10 privately owned dolichocephalic or mesaticephalic dogs free of ophthalmic disease. PROCEDURES Dogs were randomly assigned to receive doxycycline hyclate first at 5 mg/kg (2.3 mg/lb) or 10 mg/kg (4.5 mg/lb), PO, every 12 hours for 5 days, beginning on day 1. Doxycycline was administered 1 hour prior to feeding. Tear samples were collected from days 1 through 10 approximately 3 hours after the morning dose was administered. Following a 3-week washout period, dogs received the alternative dose in the same conditions. Doxycycline concentration in tear samples from 1 eye (same eye used for both sessions) was measured via liquid chromatography-mass spectrometry and compared between the 2 doxycycline doses. RESULTS Doxycycline was detected in tear samples of all dogs from days 1 through 10 for both doxycycline doses. Median peak doxycycline concentrations for the 5 mg/kg and 10 mg/kg doses were 2.19 ng/mL on day 3 and 4.32 ng/mL on day 4, respectively. Concentrations differed significantly with time, but this difference was not influenced by dose, dose order, or eye. A significant positive correlation was identified between doxycycline concentration and body weight (r = 0.22). CONCLUSIONS AND CLINICAL RELEVANCE Detectable doxycycline concentrations were achieved in the tear film of ophthalmologically normal dogs following oral administration of doxycycline at 5 or 10 mg/kg, every 12 hours. Dose had no significant effect on tear film concentration of the drug. PMID:27556265

    Recent highlights in CP violation phenomena, are reviewed. B-factory results imply that, CP-violation phase in the CKM matrix is the dominant contributor to the observed CP violation in K and B-physics. Deviations from the predictions of the CKM-paradigm due to beyond the Standard Model CP-odd phase are likely to be a small perturbation. Therefore, large data sample of clean B's will be needed. Precise determination of the unitarity triangle, along with time dependent CP in penguin dominated hadronic and radiative modes are discussed. Null tests in B, K and top-physics and separate determination of the K-unitarity triangle are also emphasized.

    At the beginning of the new millennium, ESO and its staff are facing the future with confidence. The four 8.2-m Unit Telescopes of the Very Large Telescope (VLT) are in great shape and the VLT Interferometer (VLTI) will soon have "first fringes". The intercontinental ALMA project is progressing well and concepts for extremely large optical/infrared telescopes are being studied. They can also look back at a fruitful and rewarding past year. Perhaps the most important, single development has been the rapid transition of the Very Large Telescope (VLT). From being a "high-tech project under construction" it has now become a highly proficient, world-class astronomical observatory. This trend is clearly reflected in ESO's Press Releases , as more and more front-line scientific results emerge from rich data obtained at this very efficient facility. There were also exciting news from several of the instruments at La Silla. At the same time, the ESO community may soon grow, as steps towards membership are being taken by various European countries. Throughout 2000, a total of 54 PR communications were made, with a large number of Press Photos and Video Clips, cf. the 2000 PR Index. Some of the ESO PR highlights may be accessed directly via the clickable image on the present page.

At the beginning of the year, Paranal welcomed the first Auxiliary Telescope, while on the instrument side as well, 2004 was a good year: we saw the arrival of SINFONI on the VLT, of AMBER on the VLTI, and the installation at the NACO Adaptive Optics instrument of the " Simultaneous Differential Imager (SDI)" to detect exoplanets. And the first prototype of the Astrophysical Virtual Observatory was able to provide unprecedented results on the existence of Type-2 quasars by discovering an entire population of obscured, powerful supermassive black holes. Many of these developments are described in ESO's Press Releases, most with Press Photos, cf. the 2004 PR Index.

    2005 was the year of Physics. It was thus also in part the year of astronomy and this is clearly illustrated by the numerous breakthroughs that were achieved, in particular using ESO's telescopes. One of the highlights was without any doubt the confirmation of the first image of an exoplanet , around the star 2M1207 (see ESO PR 12/05). ESO's telescopes also found a Neptune-mass exoplanet around a small star ( PR 30/05) - a discovery that proves crucial in the census of other planetary systems, and imaged a tiny companion in the close vicinity of the star GQ Lupi, a very young object still surrounded by a disc, with an age between 100,000 and 2 million years ( PR 09/05). Moreover, using a new high-contrast adaptive optics camera on the VLT, the NACO Simultaneous Differential Imager, or NACO SDI, astronomers were able for the first time to image a companion 120 times fainter than its star , very near the star AB Doradus A. This companion appears to be almost twice as heavy as theory predicts it to be ( PR 02/05). ESO's telescopes proved very useful in helping to solve a 30-year old puzzle . Astronomers have for the first time observed the visible light from a short gamma-ray burst (GRB). Using the 1.5m Danish telescope at La Silla (Chile), they showed that these short, intense bursts of gamma-ray emission most likely originate from the violent collision of two merging neutron stars ( PR 26/05). Additional evidence came from witnessing another event with the VLT ( PR 32/05). Also in this field, astronomers found the farthest known gamma-ray burst with ESO's VLT, observing an object with a redshift 6.3, i.e. that is seen when the Universe was less than 900 million years old ( PR 22/05). On July 4, NASA's Deep Impact spacecraft plunged onto Comet 9P/Tempel 1 with the aim to create a crater and expose pristine material from beneath the surface. For two days before and six days after, all major ESO telescopes have been observing the comet, in a coordinated fashion and in

    Sixty-one years after the end of the Hitler dictatorship, the history of the German Ophthalmological Society (DOG) has still hardly been investigated. According to different sources, especially the reports of the DOG congresses 1934, 1936, 1938, and 1940, the following picture can be drawn: 1. The seizure of power ("Machtergreifung") of Adolf Hitler was appreciated by most of the DOG members. 2. After a change of the constitution the DOG came under the control of the "Reichsinnenministerium". However, it escaped the egalitarianism ("Gleichschaltung") and remained relatively independent. 3. Approximately 40 % of the heads of the German university eye clinics who were the most influential DOG representatives were members of the national socialistic German working party (NSDAP). Almost all of these joined the party in 1933 or later. 4. Up to the last congress in Dresden, 1940, the DOG activities were quite extensive. After that time the activities strongly declined. 5. The "Law for the prevention of genetically disabled offspring" ("Gesetz zur Verhütung erbkranken Nachwuchses") from January 1st 1934 was intensely discussed by the DOG. Some prominent ophthalmologists and DOG members were at least in part responsible for the sterilisations because of "congenital blindness". However, as far as it is known, the DOG itself did not intervene directly concerning the practice of sterilisation. 6. Between 1932 and 1940, the DOG lost approximately 12 % of its members. Many of these stemmed from foreign countries, and many were German Jews. The latter left the DOG, as Walther Löhlein stated after the end of the war, "voluntarily". However, a main reason for leaving the DOG was very likely the feeling of being unwanted. The national socialism had several disastrous effects on ophthalmology. Although single DOG members participated in the excesses, the DOG as an organization was not directly involved. However, taking into consideration that more than 10 % of the members of the

    Lincoln Near-Earth Asteroid Research asteroid survey (LINEAR) observed proximately 10,000 deg2 of the northern sky in period roughly from 1998 to 2013. Long baseline of observations combined with good cadence and depth (14.5 < rSDSS < 17.5) provides excellent basis for investigation of variable and transient objects in this relatively faint and underexplored part of the sky. Details covering the repurposing of this survey for use in time domain astronomy, creation of a highly reliable catalogue of approximately 7,200 periodically variable stars (RR Lyrae, eclipsing binaries, SX Phe stars and LPVs) as well as search for optical signatures of exotic transient events (such as tidal disruption event candidates), are presented.

The event bought together 301 participants who presented 161 contributed talks and 120 posters, the greatest numbers up to now. The fact that most exciting items of the current astronomical research were addressed in the meeting proofs the good health of the SEA, a consolidated organization founded fifteen years ago in Barcelona. Two plenary sessions of the meeting were devoted to the approved entrance of Spain as a full member of the European Southern Observatory (ESO) and to the imminent first light of the greatest telescope in the world, the GTC (Gran Telescopio de Canarias), milestones that will certainly lead the Spanish Astronomy in the next future.

    Since 1972, Drug Metabolism Reviews has been recognized as one of the principal resources for researchers in pharmacological, pharmaceutical and toxicological fields to keep abreast of advances in drug metabolism science in academia and the pharmaceutical industry. With a distinguished list of authors and editors, the journal covers topics ranging from relatively mature fields, such as cytochrome P450 enzymes, to a variety of emerging fields. We hope to continue this tradition with the current compendium of mini-reviews that highlight novel biotransformation processes that were published during the past year. Each review begins with a summary of the article followed by our comments on novel aspects of the research and their biological implications. This collection of highlights is not intended to be exhaustive, but rather to be illustrative of recent research that provides new insights or approaches that advance the field of drug metabolism.

    Genome-wide association studies (GWAS) use high-throughput genotyping technologies to genotype thousands of single-nucleotide polymorphisms (SNPs) and relate them to the development of clinical and quantitative traits. Their use has been highly successful in the field of ophthalmology, and since the advent of GWAS in 2005, many genes not previously suspected of having a role in disease have been identified and the findings replicated. We conducted an extensive literature review and describe the concept, design, advantages, and limitations of GWAS and provide a detailed description of the applications and discoveries of GWAS in the field of eye disease to date. There have been many novel findings revealing previously unknown biological insights in a diverse range of common ocular conditions. GWAS have been a highly successful modality for investigating the pathogenesis of a wide variety of ophthalmic conditions. The insights gained into the pathogenesis of disease provide not only a better understanding of underlying disease mechanism but also offer a rationale for targeted treatment and preventative strategies. Expansive international collaboration and standardised phenotyping will permit the continued success of this investigative technique. PMID:24971990

    In these three countries the application of diagnostic ultrasound in ophthalmology is restricted, with few exceptions, only to institutions having access to in-patients. This situation is based on the organization of medical care and does not depend on the technical evolution of the equipment. Consequently the annual rate of trainees in ophthalmic ultrasound is relatively low, but a comprehensive training programme is needed in this field. The requisite training subjects are described. They include a technical and a clinical programme for both pulse-echo (A, B, M, D mode) and Doppler techniques as applied for biometry as well as for tissue and vascular examination. Some data are given regarding training facilities, aids and courses in the three countries. The concept and organization of a 5-day course (Bonn/Würzburg Course, Directors: W. Buschmann/H.G. Trier) is described in greater detail. For ophthalmic ultrasonography, testing and calibration of system parameters both for equipment and transducers is necessary for obtaining reliable and reproducible results. Examples are given for the organization of technical training in the practical course. The 1981 guidelines of the "Kassenärztliche Bundesvereinigung", Cologne, are discussed. These regulations define minimum requirements for both ultrasonic training and equipment in the FRG. Finally, a few controversial aspects of the teaching (quality assurance, role of biometry) are mentioned. PMID:9417602

    The purpose of this study was to evaluate the need for nationwide assessment of surgical skills during residency, and to define ideal methods for assessment in three surgical disciplines: ophthalmology, orthopedics and gastrointestinal surgery. Three online questionnaires were sent by e-mail to 784 residents, fellows and hospital practitioners, and 119 university hospital physican-professors. Questionnaires focused on current assessment methods at the regional level, the roles of the surveyed population in these evaluations, potential obstacles to their development and the most relevant methods for practical evaluations. Nine hundred and three questionnaires were sent; 355 participants replied (response rate: 39%). The establishment of systematic assessment seemed necessary to over 90% of the survey population, and this opinion was equitably distributed among all three specialties. Over 60% of respondents felt that current assessment procedures were not satisfactory. In all three specialties, the ideal evaluation method proposed was a real patient procedure. This "in vivo" evaluation was considered applicable in 80% of cases, potential barriers to its development being the resident's anxiety, medical-legal reasons and the lack of objective criteria. The ideal timing of these assessments was bi-annual. Implementation of surgical skills assessment during residency seems necessary. The survey population appears dissatisfied with current arrangements. A step-by-step evaluation combining surgical simulations, animal training and live patient procedures may be appropriate.

    AIM To report the indications for and techniques of corneal transplantation at Vietnam National Institute of Ophthalmology (VNIO) over a period of 12y (2002-2013). METHODS Records of patients who had undergone corneal transplantation at VNIO from January 1, 2002 to January 1, 2014 were reviewed to determine the indication for and type of corneal transplant performed. Patient age, gender, indication for corneal transplantation and surgical technique were recorded and analyzed. RESULTS Corneal transplantation were underwent in 1390 eyes of 1278 patients with a mean age of 44.9±18.1y during the period under review. The most common indication was infectious corneal ulcer (n=670; 48.2%), followed by corneal scar (n=333, 24.0%), corneal dystrophy (n=138, 9.9%) and failed graft (n=112, 8.1%). Nearly all procedures performed were penetrating keratoplasty (n=1300, 93.5%), with a few lamellar keratoplasty procedures performed: lamellar keratoplasty (n=52, 3.7%), Descemet's stripping automated endothelial keratoplasty (n=27, 1.9%) and deep anterior lamellar keratoplasty (n=11, 0.8%). CONCLUSION While the most common indication for keratoplasty was infectious keratitis, nearly all indications for corneal transplantation were managed with penetrating keratoplasty. However, lamellar keratoplasty techniques, including deep anterior lamellar keratoplasty and Descemet's stripping automated endothelial keratoplasty, are being performed with increasing frequency for isolated stromal and endothelial disorders, respectively.

    Background: Although lecture handouts are commonly given to students during theory lectures, students’ perception, as well as their performance, can vary depending on the type of handouts they receive for information processing. Methodology: This is a quasi-experimental study involving 6th semester medical students. The study was conducted during theory lectures on ophthalmology. The two types of notes given to the students were comprehensive handout and a skeleton handout, which included some lecture notes but required substantial annotation by the students. Pre-test and post-test in the form of multiple choice questions were conducted before and after the lecture session, respectively. Results: There was a significant difference of mean score of pre- and post-test between skeletal handout (pre = 1.85 ± 1.275, post = 4.85 ± 0.363) and full handout (pre = 1.92 ± 1.09 post = 2.61 ± 0.771) with P < 0.001. However, the students’ responses to questionnaires indicated a strong preference for much detailed handouts as essential to preparation for examinations. Conclusion: The student can improve their performance during examination while working on skeletal handouts during theory lectures in spite of showing a preference for complete handouts.

    Medical education, associated with lengthy, exhaustive pathways requisite of time, energy and efforts, restrain an individual from pursuing a career in medicine. Most students enrol in medical colleges under the influence of their family members, and only some strive to seek medicine as their own ambition. Medical students confront a number of problems in memorising huge amount of data and the various strategies are integrated in MBBS curriculum from time to time. After MBBS programme, most graduates tend to abandon studies, some migrate abroad, a few continue as general physicians and even fewer strive to get registered for postgraduate specialisation. This results in suboptimal supply of medical workforce. Inconsideration of the current ophthalmologist work ratio and growing demand for eye care services, an initiative is put forward to introduce Bachelors of Ophthalmic Surgery programme similar to Bachelor of Dental Surgery. Such initiative may facilitate effective learning, enable command in a particular area and encourage more individuals to pursue a career in ophthalmology. Using a questionnaire to undergraduate medical students, medical professors and ophthalmologists were surveyed to evaluate the efficacy of the proposed initiative. The results threw a mixed response.

    In the 19th century, the process of social and political changes in the Polish society was considerably affected by the development of sciences, especially medicine. Many doctors were involved in voluntary health services and public education of the poorest social classes and in supporting government authorities which promoted health education and proper sanitation among the public. The article presents the intellectual biography of dr Emanuel Emeryk Machek, who was one of the most prominent doctors of that time, a competent clinician who trained many doctors and was engaged in voluntary work for the public. His medical career is connected with the history of Lviv University--Dr Emanuel Emeryk Machek was the founder of the Ophtalmic Hospital at the Medical Department of Lviv University. One of the students of dr Emanuel Emeryk Machek was dr Boleslaw Dlugoszowski, who is mostly remembered not as a doctor but as a great patriot, brave soldier fighting in the cavalry regiment, a friend and aide-de-camp of Marshall J6zef Pilsudski, a diplomat assigned by President Ignacy Moscicki to become his successor, and the President of Poland in October 1939. history of medicine, history of ophthalmology, Lviv University, history of Polish science under partitions, Boleslaw Wieniawa Dlugoszowski, Emanuel Emeryk Machek.

    2013-01-01

    Purpose of review The thalidomide tragedy of the early 1960s resulted in a great number of studies and reports involving many specialties of medicine. Because of the estimated large number of affected children (5000+) worldwide exposed to this potent teratogen, and the many informative cases in which the exposure time was known, a teratogenic timetable was constructed relating affected structures to the time of exposure. This demonstrated that thalidomide had a teratogenic effect between approximately 20 to 36 days after fertilization. Recent findings We found that Duane syndrome and its variants were prominent in individuals who were exposed to thalidomide early in the sensitive period (days 20 to 26±). Other anomalies associated with this early effect were aberrant tearing, facial nerve palsy, ear malformations, and autism. Structural eye malformations were less frequent in this early phase, appearing slightly later in the sensitive period. Summary This study summarizes the ophthalmologic findings from a number of studies and compares them with respect to the implications of time of exposure. Because the timing of anomalies such as external ear and limb malformations are well established in the thalidomide literature, correlation with associated eye anomalies gives insight into the approximate timing of the causative teratogen exposure.

    The amniotic membrane (AM) is the inner layer of the fetal membranes and consist of 3 different layers: the epithelium, basement membrane and stroma which further consists of three contiguous but distinct layers: the inner compact layer, middle fibroblast layer and the outermost spongy layer. The AM has been shown to have anti-inflammatory, anti-fibrotic, anti-angiogenic as well as anti-microbial properties. Also because of its transparent structure, lack of immunogenicity and the ability to provide an excellent substrate for growth, migration and adhesion of epithelial corneal and conjunctival cells, it is being used increasingly for ocular surface reconstruction in a variety of ocular pathologies including corneal disorders associated with limbal stem cell deficiency, surgeries for conjunctival reconstruction, as a carrier for ex vivo expansion of limbal epithelial cells, glaucoma surgeries and sceral melts and perforations. However indiscriminate use of human AM needs to be discouraged as complications though infrequent can occur. These include risk of transmission of bacterial, viral or fungal infections to the recipient if the donors are not adequately screened for communicable diseases, if the membrane is not processed under sterile conditions or if storage is improper. Optimal outcomes can be achieved only with meticulous case selection. This review explores the ever expanding ophthalmological indications for the use of human AM. PMID:25032100

    Victor Szokalski is considered to be the father of Polish ophthalmology. He was born in Warsaw in 1811, where he also began his medical studies. He fought in the November's Uprising. He was awarded the Military Cross Virtuti. After its fall he went to Germany, where he continued his studies. In 1834 he defended his doctoral thesis. Then he moved to France, where worked at the Eye Clinic of Jules Sichel. He wrote many articles for medical journals and taught students. Already in Paris he acted in a number of social societies, collaborated with Prince Adam Czartoryski, was a friend of Adam Mickiewicz. Fifteen years later he returned to Warsaw, where became a consultant, then the chief at the Ophthalmic Institute. For 33 years he has served as secretary of the Warsaw Medical Society. He wrote the first Polish original textbook of ophthalmology. He died in Warsaw in 1891. PMID:22256575

    Last year proved to be another exceptional year for the European organisation for ground-based astronomy. ESO should begin the New Year with two new member states: Spain (PR 05/06) and the Czech Republic (PR 52/06). ESO PR Highlights 2006 2006 was a year of renovation and revolution in the world of planets. A new Earth-like exoplanet has been discovered (PR 03/06) using a network of telescopes from all over the world (including the Danish 1.54-m one at ESO La Silla). It is not the only child of this fruitful year: thanks to the combined use of ESO's Very Large Telescope (VLT) and La Silla instruments, a surprising system of twin giant exoplanets was found (PR 29/06), and a trio of Neptune-like planets hosted by a nearby star were identified (PR 18/06). These results open new perspectives on the search for habitable zones and on the understanding of the mechanism of planet formation. The VISIR instrument on the VLT has been providing unique information to answer this last question, by supplying a high resolution view of a planet-forming disc (PR 36/06). There are not only new members in the planets' register: during the General Assembly of the International Astronomical Union held in Prague (Czech Republic), it was decided that Pluto is not a planet anymore but a 'dwarf planet'. Whatever its status, Pluto still has a satellite, Charon, whose radius and density have been measured more accurately by observing a rare occultation from different sites, including Cerro Paranal (PR 02/06). The scientific community dedicated 2006 to the great physicist James Clerk Maxwell (it was the 175th anniversary of the birth): without his electromagnetic theory of light, none of the astonishing discoveries of modern physics could have been achieved. Nowadays we can look at distant galaxies in great detail: the GIRAFFE spectrograph on the VLT revealed that galaxies 6 billion years ago had the same amount of dark matter relative to stars than nowadays (PR 10/06), while SINFONI gave an

    Two tests supporting development of the launch abort system for the Orion MultiPurpose Crew Vehicle were run in the NASA Ames Unitary Plan wind tunnel last year. The first test used a fully metric model to examine the stability and controllability of the Launch Abort Vehicle during potential abort scenarios for Mach numbers ranging from 0.3 to 2.5. The aerodynamic effects of the Abort Motor and Attitude Control Motor plumes were simulated using high-pressure air flowing through independent paths. The aerodynamic effects of the proximity to the launch vehicle during the early moments of an abort were simulated with a remotely actuated Service Module that allowed the position relative to the Crew Module to be varied appropriately. The second test simulated the acoustic environment around the Launch Abort Vehicle caused by the plumes from the 400,000-pound thrust, solid-fueled Abort Motor. To obtain the proper acoustic characteristics of the hot rocket plumes for the flight vehicle, heated Helium was used. A custom Helium supply system was developed for the test consisting of 2 jumbo high-pressure Helium trailers, a twelve-tube accumulator, and a 13MW gas-fired heater borrowed from the Propulsion Simulation Laboratory at NASA Glenn Research Center. The test provided fluctuating surface pressure measurements at over 200 points on the vehicle surface that have now been used to define the ground-testing requirements for the Orion Launch Abort Vehicle.

    INTRODUCTION. Phenylketonuria (PKU) is an autosomal recessive metabolic disease caused by a deficiency of phenylalanine hydroxylase. The dietary therapy for the effective management of PKU, in particular the restriction of high-protein foods of animal-origin, compromises patients' intake of fat and distorts the n-3:n-6 ratio of essential fatty acids in the diet. This deficiency can contribute to neurological and visual impairment. AIM. To evaluate changes in white matter alterations, visual evoked potential (VEP) latencies and performance in executive and motor functions in a group of early and continuously treated PKU patients after supplementation with docosahexaneoic acid (DHA). PATIENTS AND METHODS. We selected 21 PKU patients with early diagnosis (age range: 9-25 years), on a Phe-restricted diet and supplemented with PKU formula. Inclusion criteria were: low erythrocyte DHA values, prolonged P100 wave latencies in VEP and/or presence of white matter hyperintensities on brain magnetic resonance imaging (MRI), and intellectual quotient > 80. All patients were treated with DHA (10 mg/kg/day) for 12 months. Assessment was conducted at baseline and after 12 months of treatment, and included biochemical parameters, brain MRI, VEP, ophthalmologic evaluation and neuropsychological tests. RESULTS AND CONCLUSION. All the patients normalized the DHA levels after supplementation. Improvement in the P100 wave latencies, and fine motor skills was significant. No significant improvement in the other explorations was evident after supplementation. Further investigations seem advisable to establish a cause-effect relationship between DHA treatment and the slight improvement observed in some neurological functions. PMID:22829083

    Improvement in clinic efficiency in the ambulatory setting is often looked at as an area for development of lean management strategies to deliver a higher quality of healthcare while reducing errors, costs, and delays. To examine the benefits of improving team communication and its impact on clinic flow and efficiency, we describe a time-motion study performed in an academic outpatient Ophthalmology clinic and its objective and subjective results. Compared to clinic encounters without the use of the portable radios, objective data demonstrated an overall significant decreases in mean workup time (15.18 vs. 13.10), room wait (13.10 vs. 10.47), and decreased the total time needed with an MD per encounter (9.45 vs. 6.63). Subjectively, significant improvements were seen in careprovider scores for patient flow (60.78 vs. 84.29), getting assistance (61.89 vs. 88.57), moving patient charts (54.44 vs. 85.71), teamwork (69.56 vs. 91.0), communications (62.33 vs. 90.43), providing quality patient care (76.22 vs. 89.57), and receiving input on the ability to see walk-in patients (80.11 vs. 90.43). For academic purposes, an improvement in engagement in patient care and learning opportunities was noted by the clinic resident-in-training during the pilot study. Portable radios in our pilot study were preferred over the previous method of communication and demonstrates significant improvements in certain areas of clinical efficiency, subjective perception of teamwork and communications, and academic learning.

    PURPOSE: To examine the ophthalmologic experience with the shaken baby syndrome (SBS) at one medical center, including clinical findings, autopsy findings, and the visual outcome of survivors. METHODS: One hundred sixteen patients admitted from 1987 to 1998 for subdural hematomas of the brain secondary to abuse were included. RESULTS: Retinal hemorrhages were detected in 84% of the children, but this important finding had been missed often by nonophthalmologists. Poor visual response, poor pupillary response, and retinal hemorrhage correlated strongly with demise of the child. One child who died had pigmented retinal scars from previous abuse, a condition not previously observed histopathologically. The clinical and autopsy findings varied somewhat, probably because of the differing conditions for examination. No correlation could be made between computerized tomography scans done during life and the subdural hemorrhage of the optic nerve found on autopsy. Half of the surviving patients were known to have good vision. One fourth of the patients had poor vision, largely due to cerebral visual impairment from bilateral injury posterior to the optic chiasm. Severe neurologic impairment correlated highly with loss of vision. CONCLUSION: This series provides information on the frequency of eye findings in SBS patients. No fundus finding is pathognomonic for SBS. When retinal hemorrhages are found in young children, the likelihood that abuse occurred is very high. The difficulty that nonophthalmologists have in detecting retinal hemorrhage may be an important limiting factor in finding these children so they may be protected from further abuse.

    Purpose The purpose of this study was to ascertain the frequency and risk factors of dry eye (DE) among patients attending a tertiary care ophthalmology center in Mexico. Methods Approximately 338 consecutive new patients attending a tertiary care ophthalmology center in Mexico City underwent an ocular surface examination, which included tear film break-up time, fluorescein corneal staining, Schirmer’s test, and evaluation of meibum quality. Symptoms of DE were evaluated by the Ocular Surface Disease Index and Dry Eye Questionnaire-5. Information on demographics, exposures, past medical and ocular history, and medications was also collected. Results The frequency of severe DE symptoms was found to be 43% based on the Ocular Surface Disease Index and 30% based on Dry Eye Questionnaire-5. Risk factors significantly associated with increased DE symptoms included dry mouth and gastrointestinal ulcer medications. With regard to signs, aqueous tear deficiency was a less-frequent finding (22%) in our population than evaporative deficiency (94%). Risk factors associated with aqueous tear deficiency were dry mouth and diuretic use. No risk factors were associated with evaporative deficiency. Risk factors associated with meibomian gland dysfunction included old age, male sex, arthritis, and use of an antihypertensive. The only risk factor associated with corneal staining was dry mouth. Conclusion This is the first study to demonstrate the frequency of symptomatic and clinical DE in a tertiary care ophthalmology center in Mexico. The frequency of DE ranged from 30% using a symptomatic definition to 94% using objective measures. Different risk factors were found for different aspects of DE, suggesting differing underlying pathophysiologies behind different DE subtypes. PMID:27499613

    The ISOLDE online mass separator located at CERN provides a large variety of radioactive ion beams for research on nuclear physics, nuclear astrophysics, fundamental interactions, atomic physics, radiochemistry, nuclear medicine, condensed matter science, life sciences and others. The recently operational REX-ISOLDE post-accelerator is capable of accelerating the isotopes produced at ISOLDE to energies of up to 3.0MeV/u by using an ion trap and charge breeder and a compact linear accelerator structure. The post-accelerator is complemented by a highly segmented Ge array in conjunction with a compact silicon strip detector at one of the secondary target positions, while a general spectroscopy setup occupies a second station. REX-ISOLDE has opened up the possibility of nuclear spectroscopy studies by means of transfer reactions and Coulomb excitation of exotic nuclei. The facility maintains an extensive physics-driven target and ion source development program, which has helped ISOLDE keep its international status for more than 35 years. Some recent experimental highlights and technical developments are discussed.

  7. Highlighting impact: Do editors' selections identify influential papers?

    NASA Astrophysics Data System (ADS)

    Antonoyiannakis, Manolis

    A recent trend in scientific publishing is that journal editors highlight each week a select set among the papers published (usually) in their respective journals. The highlighted papers are deemed of higher quality, importance, or interest than the 'average' paper and feature prominently in the publishers' websites. We perform a citation analysis of the highlighted papers for a number of journals from various publishers in physics. By comparing the performance of highlighted papers relative to (a) typical papers and (b) highly cited papers in their source journals and in other journals in the field, we explore whether, and to what extent, the selection process at the time of publication identifies papers that will turn out to be influential. We discuss the broader implications for research assessment.

  8. Highlights of recent balance of system research and evaluation

    The cost of most photovoltaic (PV) systems is more a function of the balance of system (BOS) components than the collectors. The exception to this rule is the grid-tied system whose cost is related more directly to the collectors, and secondarily to the inverter/controls. In fact, recent procurements throughout the country document that collector costs for roof-mounted, utility-tied systems (Russell, PV Systems Workshop, 7/94) represent 60% to 70% of the system cost. This contrasts with the current market for packaged stand-alone all PV or PV-hybrid systems where collectors represent only 25% to 35% of the total. Not only are the BOS components the cost drivers in the current cost-effective PV system market place, they are also the least reliable components. This paper discusses the impact that BOS issues have on component performance, system performance, and system cost and reliability. We will also look at recent recommended changes in system design based upon performance evaluations of fielded PV systems.

  12. Using Highlighting to Train Attentional Expertise.

    Roads, Brett; Mozer, Michael C; Busey, Thomas A

    2016-01-01

    Acquiring expertise in complex visual tasks is time consuming. To facilitate the efficient training of novices on where to look in these tasks, we propose an attentional highlighting paradigm. Highlighting involves dynamically modulating the saliency of a visual image to guide attention along the fixation path of a domain expert who had previously viewed the same image. In Experiment 1, we trained naive subjects via attentional highlighting on a fingerprint-matching task. Before and after training, we asked subjects to freely inspect images containing pairs of prints and determine whether the prints matched. Fixation sequences were automatically scored for the degree of expertise exhibited using a Bayesian discriminative model of novice and expert gaze behavior. Highlighted training causes gaze behavior to become more expert-like not only on the trained images but also on transfer images, indicating generalization of learning. In Experiment 2, to control for the possibility that the increase in expertise is due to mere exposure, we trained subjects via highlighting of fixation sequences from novices, not experts, and observed no transition toward expertise. In Experiment 3, to determine the specificity of the training effect, we trained subjects with expert fixation sequences from images other than the one being viewed, which preserves coarse-scale statistics of expert gaze but provides no information about fine-grain features. Observing at least a partial transition toward expertise, we obtain only weak evidence that the highlighting procedure facilitates the learning of critical local features. We discuss possible improvements to the highlighting procedure. PMID:26744839

    Abstract Purpose: Assessment of ocular involvement in transthyretin-related familial amyloidosis with polyneuropathy (FAP) in a large cohort of Portuguese patients. Methods: We reviewed the medical records of 513 Portuguese FAP mutation carriers, at the Ophthalmology Service, Centro Hospitalar do Porto, between 1 January 2008 and 31 January 2013. Abnormal conjunctiva vessels (ACV), Schirmer test, tear break-up time (TBUT), amyloid deposition on the iris (DAI), scalloped iris, amyloid deposition on the anterior capsule of the lens (DAL), vitreous amyloidosis, retinal amyloid angiopathy and glaucoma were evaluated and registered. Results: Of the 513 carriers, 477 (93%) had clinical systemic disease with a median duration of 9.3 (5.1–13.7) years and 247 were men. Of these, 343 (72%) had been liver transplanted, on median of 6.6 (3.3–10.8) years before inclusion in this study. No ocular abnormalities were identified in the asymptomatic carriers (7%). The abnormalities observed with decreasing frequency were abnormal TBUT (379 patients, 79.5%, 751 eyes), abnormal Schirmer test (320 patients, 67%, 635 eyes), DAI (183 patients, 38.4%, 350 eyes), DAL (157 patients, 32.9%, 308 eyes), scalloped iris (133 patients, 27.9%, 238 eyes), glaucoma (97 patients, 20%, 165 eyes), vitreous amyloidosis (83 patients, 17.4%, 139 eyes), ACV (68 patients, 14%, 136 eyes) and amyloidotic retinal angiopathy (21 patients, 4%, 32 eyes). Patients with abnormal Schirmer test (p < 0.001), scalloped iris (p = 0.006) and vitreous amyloidosis (p = 0.007) were significantly older than the others. According to their age of onset of systemic disease, the patients have been split into early-onset (<40 years old), intermediate-onset (40–50 years old), late onset (>50 years old) and asymptomatic carriers. We observed a statistically significant difference in the prevalence of ACV (p = 0.045) and of an abnormal Schirmer test (p = 0.004) between groups. Transplanted patients have a

    In this paper, we proposed a two-step algorithm based on the combination of the exemplar-based algorithm and the illumination model to deal with specular images, especially those contain saturated pixels in the highlight areas. First the proposed modified exemplar-based algorithm is employed to process the unsaturated specular pixels under the supervision of illumination model. Then we inpaint the rest regions in which the pixels are saturated with original exemplar-based algorithm to obtain the final result. Experimental results demonstrate that the proposed algorithm performs better on the images with saturated pixels in the highlight areas compared with classical highlight removal and image inpainting algorithms.

  16. Mars geologic mapping program: Review and highlights

    1991-01-01

    The Mars Geologic Mapping (MGM) Program was introduced by NASA in 1987 as a new initiative in the Planetary Geology and Geophysics (PGG) Program. The overall purpose of the program is to support research on topical science problems that address specific questions. Among the objectives of the project are: (1) to produce highly detailed geologic maps that will greatly increase the knowledge of the materials and processes that have contributed to the evolutionary history of Mars; (2) to define areas of special interest for possible future investigation by planned missions (Mars Observer, Mars Sample Return); and (3) to maintain the interest of the planetary community in the development of new concepts and the re-evaluation of Martian geology as new data in usable form become available. Some interesting highlights of the geologic mapping indicate that multiple flood episodes occurred at different times during the Hesperian Period in both Kasei and Maja Valles. Studies of small channels in the Memnonia, Mangala, and Tharsis regions show that fluvial events appear to have occurred during the Amazonian Period at equatorial latitudes. Flood waters occurred during the Amazonian Period at equatorial latitudes. Flood waters from Mangala Valles may have seeped into surficial materials with the subsequent development of numerous sapping channels and debris flows; this suggests that the ancient highland terrain consists of relatively unconsolidated materials. Multiple layers were observed for the first time in the ridged plains lava flows covering large areas of Lunae Planum; some wrinkle ridges in this area are associated with grabens and collapse volcanic units at Hadriaca and Tyrrhena Paterae indicates that the units may have been emplaced by gravity-driven pyroclastic flows. Unlike the north polar layered deposits, those in the south polar region show no angular unconformities or evidence of faulting and folding. Water ice in the south polar layered deposits may be protected

    Importance Optimization of glycemic control is critical to reduce diabetes related complications, but long-term success is challenging. Although vision loss is among the greatest fears of individuals with diabetes, comprehensive personalized diabetes education and risk assessments are not consistently employed in ophthalmology settings. Objective To determine whether point-of-care measurement of HbA1c and personalized diabetes complication risk assessments performed during retinal ophthalmology visits improve glycemic control as assessed by HA1c. Design/Setting Ophthalmologist office based clinical trial where investigators from 42 sites were randomly assigned to provide either study-prescribed augmented diabetes assessment and education, or usual care. Participants Adults with type 1 or 2 diabetes enrolled into two cohorts: “more frequent” than annual follow-up (502 control and 488 intervention participants) and “annual” follow-up (368 and 388 participants). Intervention(s) Point-of-care measurement of HbA1c, blood pressure, and retinopathy severity; individualized estimate of retinopathy progression risk derived from the visit findings; structured comparison and review of past and current clinical findings; and structured education with immediate assessment and feedback regarding participant understanding. Intervention was performed at enrollment and routine ophthalmic follow-up visits scheduled at least 12 weeks apart. Main Outcome Measure(s) Mean change in HbA1c from baseline to 1 year. Secondary outcomes included body mass index, blood pressure, and diabetes self-management practices and attitudes surveys. Results In the “more frequent” cohort, mean (SD) change in HbA1c at 1 year was −0.1% (1.5%) in the control group and −0.3% (1.4%) in the intervention group (adjusted mean difference −0.09%, 95% confidence interval −0.29% to +0.12%, P=0.35). In the “annual” cohort, mean (SD) change in HBA1c was 0.0% (1.1%) and −0.1% (1

    Display format and highlight validity were shown to affect visual display search performance; however, these studies were conducted on small, artificial displays of alphanumeric stimuli. A study manipulating these variables was conducted using realistic, complex Space Shuttle information displays. A 2x2x3 within-subjects analysis of variance found that search times were faster for items in reformatted displays than for current displays. Responses to valid applications of highlight were significantly faster than responses to non or invalidly highlighted applications. The significant format by highlight validity interaction showed that there was little difference in response time to both current and reformatted displays when the highlight validity was applied; however, under the non or invalid highlight conditions, search times were faster with reformatted displays. A separate within-subject analysis of variance of display format, highlight validity, and several highlight methods did not reveal a main effect of highlight method. In addition, observed display search times were compared to search time predicted by Tullis' Display Analysis Program. Benefits of highlighting and reformatting displays to enhance search and the necessity to consider highlight validity and format characteristics in tandem for predicting search performance are discussed.

    2015-01-01

    Purpose: To describe the design, implementation, and evaluation of a tele-education system developed to improve diagnostic competency in retinopathy of prematurity (ROP) by ophthalmology residents. Methods: A secure Web-based tele-education system was developed utilizing a repository of over 2,500 unique image sets of ROP. For each image set used in the system, a reference standard ROP diagnosis was established. Performance by ophthalmology residents (postgraduate years 2 to 4) from the United States and Canada in taking the ROP tele-education program was prospectively evaluated. Residents were presented with image-based clinical cases of ROP during a pretest, posttest, and training chapters. Accuracy and reliability of ROP diagnosis (eg, plus disease, zone, stage, category) were determined using sensitivity, specificity, and the kappa statistic calculations of the results from the pretest and posttest. Results: Fifty-five ophthalmology residents were provided access to the ROP tele-education program. Thirty-one ophthalmology residents completed the program. When all training levels were analyzed together, a statistically significant increase was observed in sensitivity for the diagnosis of plus disease, zone, stage, category, and aggressive posterior ROP (P<.05). Statistically significant changes in specificity for identification of stage 2 or worse (P=.027) and pre-plus (P=.028) were observed. Conclusions: A tele-education system for ROP education is effective in improving diagnostic accuracy of ROP by ophthalmology residents. This system may have utility in the setting of both healthcare and medical education reform by creating a validated method to certify telemedicine providers and educate the next generation of ophthalmologists.

    Medical knowledge in India began to be introduced to China in earliest from the Later Han Dynasty period to the times of Wei-Qin and South & North Dynasties. This is proved by many Buddhist medical books appeared in those days. Of the contents of Indian medicine, the theory of four major elements affected Chinese medicine more than did the theory of body fluids. Based on the theory of four major elements that was began to be introduced in Fú shuō fú yī jīng, an attempt to establish a new medical system was made in Zhŏu hòu băi yīfāng written by Táo Hóng-jĭng and Sūn Sī-miăo who tried to develop etiology further but could not achieve any great outcomes. Unlike the foregoing situation, Indian medicine aroused a large echo in China in the field of ophthalmology with ophthalmological knowledge mentioned in Suśrutasa hitā and 'Jīnzhēn-shù'(cataract couching) introduced as a surgical treatment of cataract. The Suśrutasa hitā which is one of the three major texts of Indian medicine contains additional information on surgical operations not introduced in the Carakasa hitā. The technique of cataract surgery was particularly popular in the Tang and Song dynasty periods in China under the name Lóng shù pú sà yăn lùn(The Ophthalmological Treatise of Bodhisattva Nāgārjuna) or Lóng shù lùn and was even designated as a subject to educate medical officers. While the original text of Lóng shù pú sà yăn lùn was not handed down, the first testimony that show the trace of the introduction of this text into China was the Tiān zhú jīng lùn yăn mentioned in Wài tái mì yào(Arcane Essential from the Imperial Library) written by Wang Tao. Long shàng dào ren who was mentioned as the compiler of the book is assumed to be Lóng shù. Although Tiān zhú jīng lùn yăn introduced anatomical knowledge about the eyeball that could have not been in the traditional Chinese medicine, this book has only limited quantity of information in this

  20. Highlighting relatedness promotes prosocial motives and behavior.

    2011-07-01

    According to self-determination theory, people have three basic psychological needs: relatedness, competence, and autonomy. Of these, the authors reasoned that relatedness need satisfaction is particularly important for promoting prosocial behavior because of the increased sense of connectedness to others that this engenders. In Experiment 1, the authors manipulated relatedness, autonomy, competence, or gave participants a neutral task, and found that highlighting relatedness led to higher interest in volunteering and intentions to volunteer relative to the other conditions. Experiment 2 found that writing about relatedness experiences promoted feelings of connectedness to others, which in turn predicted greater prosocial intentions. Experiment 3 found that relatedness manipulation participants donated significantly more money to charity than did participants given a neutral task. The results suggest that highlighting relatedness increases engagement in prosocial activities and are discussed in relation to the conflict and compatibility between individual and social outcomes.

The activities from other flights days can be seen on 'STS-109 Mission Highlights Resource Tape' Part 1 of 4 (internal ID 2002139471), 'STS-109 Mission Highlights Resource Tape' Part 3 of 4 (internal ID 2002139476), and 'STS-109 Mission Highlights Resource Tape' Part 4 of 4 (internal ID 2002137577). The primary activities during these days were EVAs (extravehicular activities) to replace two solar arrays on the HST (Hubble Space Telescope). Footage from flight day 4 records an EVA by Grunsfeld and Linnehan, including their exit from Columbia's payload bay airlock, their stowing of the old HST starboard rigid array on the rigid array carrier in Columbia's payload bay, their attachment of the new array on HST, the installation of a new starboard diode box, and the unfolding of the new array. The pistol grip space tool used to fasten the old array in its new location is shown in use. The video also includes several shots of the HST with Earth in the background. On flight day 5 Newman and Massimino conduct an EVA to change the port side array and diode box on HST. This EVA is very similar to the one on flight day 4, and is covered similarly in the video. A hand operated ratchet is shown in use. In addition to a repeat of the previous tasks, the astronauts change HST's reaction wheel assembly, and because they are ahead of schedule, install installation and lubricate an instrument door on the telescope. The Earth views include a view of Egypt and Israel, with the Nile River, Red Sea, and Mediterranean Sea.

    2014-09-18

    Exoplanets are now being discovered in profusion. To understand their character, however, we require spectral models and data. These elements of remote sensing can yield temperatures, compositions and even weather patterns, but only if significant improvements in both the parameter retrieval process and measurements are made. Despite heroic efforts to garner constraining data on exoplanet atmospheres and dynamics, reliable interpretation has frequently lagged behind ambition. I summarize the most productive, and at times novel, methods used to probe exoplanet atmospheres; highlight some of the most interesting results obtained; and suggest various broad theoretical topics in which further work could pay significant dividends.

    2014-09-01

    Exoplanets are now being discovered in profusion. To understand their character, however, we require spectral models and data. These elements of remote sensing can yield temperatures, compositions and even weather patterns, but only if significant improvements in both the parameter retrieval process and measurements are made. Despite heroic efforts to garner constraining data on exoplanet atmospheres and dynamics, reliable interpretation has frequently lagged behind ambition. I summarize the most productive, and at times novel, methods used to probe exoplanet atmospheres; highlight some of the most interesting results obtained; and suggest various broad theoretical topics in which further work could pay significant dividends.

    Purpose. To examine financial and clinical work productivity outcomes associated with the use of the electronic health record (EHR). Methods. 191,360 billable clinical encounters were analyzed for 12 clinical providers over a 9-year study period during which an EHR was implemented. Main outcome measures were clinical revenues collected per provider and secondary outcomes were charge capture, patient visit coding levels, transcription costs, patient visit volume per provider, digital drawing, and digital imaging volume. Results. The difference in inflation adjusted net clinical revenue per provider per year did not change significantly in the period after EHR implementation (mean = $404,198; SD = $17,912) than before (mean = $411,420; SD = $39,366) (P = 0.746). Charge capture, the proportion of higher- and lower-level visit codes for new and established patients, and patient visits per provider remained stable. A total savings of $188,951 in transcription costs occurred over a 4-year time period post-EHR implementation. The rate of drawing the ophthalmic exam in the EHR was low (mean = 2.28%; SD = 0.05%) for all providers. Conclusions. This study did not show a clear financial gain after EHR implementation in an academic ophthalmology practice. Ophthalmologists do not rely on drawings to document the ophthalmic exam; instead, the ophthalmic exam becomes text-driven in a paperless world. PMID:25810920

    Purpose To assess the diagnostic yield and the practicality of implementing whole exome sequencing within a clinical ophthalmology setting. Design Evaluation of a diagnostic protocol. Methods Setting Patient participants were enrolled during clinical appointments in a university based Ophthalmic Genetics clinic. Patient Population Twenty-six patients with a variety of presumed hereditary retinal dystrophies. Intervention: Participants were offered whole exome sequencing in addition to clinically available sequencing gene panels between July 2012 and January 2013 to determine the molecular etiology of their retinal dystrophy. Main Outcome Measures Diagnostic yield and acceptability of whole exome sequencing in patients with retinal disorders. Results Twenty-six of 29 (~90%) eligible patients who were approached opted to undergo molecular testing. Each participant chose whole exome sequencing in addition to, or in lieu of, clinically available sequencing gene panels. Time to obtain informed consent was manageable in the clinical context. Whole exome sequencing successfully identified known pathogenic mutations or suspected deleterious variants in 57.7% of participants. Additionally, one participant had 2 autosomal dominant medically actionable incidental findings (unrelated to retinopathy) that were reported to enable the participant to take preventive action and reduce risk for future disease. Conclusions In this study, we identified the molecular etiology for more than half of all participants. Additionally, we found that participants were widely accepting of whole exome sequencing and the possibility of being informed about medically actionable incidental findings. PMID:25910913

    While investigative ophthalmologists access peer-reviewed journals as part of their daily routine, and while they regularly visit scientific congresses, they rarely peruse patent documents as an information source. Among the reasons for this negligence are the incompatibility of patent search algorithms with those known from journal databases, a legalistic and frequently redundant language, and misconceptions about the nature of the patenting system. Here we present key data and analyses from the ophthalmology module of a patent database system that we are developing to address some of these problems. We show that international patent applications consistently reflect developer interest in the ocular drug and diagnostics field; that they are technically focused lead indicators of developments that frequently feature in peer-reviewed patenting only much later; and that patenting targets are well aligned with the unmet therapeutic needs of populations in industrialized countries. Most applications (74%–78% in years since 2006) are supported with experimental data, and most (on average, 80%–90%) faced at least one objection to patentability during their initial stage of examination. In contrast to the peer-reviewed scenery that is highly diverse, the corresponding patenting arena shows a pronounced focus on the United States. PMID:19668552

    The FY 1996 budget presentation is organized by the Department`s major business lines. An accompanying chart displays the request for new budget authority. The report compares the budget request for FY 1996 with the appropriated FY 1995 funding levels displayed on a comparable basis. The FY 1996 budget represents the first year of a five year plan in which the Department will reduce its spending by $15.8 billion in budget authority and by $14.1 billion in outlays. FY 1996 is a transition year as the Department embarks on its multiyear effort to do more with less. The Budget Highlights are presented by business line; however, the fifth business line, Economic Productivity, which is described in the Policy Overview section, cuts across multiple organizational missions, funding levels and activities and is therefore included in the discussion of the other four business lines.

  10. Pulsars, PTAs, and PALFA: Highlights and Opportunities

    2015-08-01

    The detection of gravitational waves with nanohertz frequencies from SMBHs in merging galaxies, either a single source or a background, is greatly aided by increasing the sensitivity of pulsar timing arrays (PTAs). Increasing the number of millisecond pulsars in PTAs is one of the best ways to enhance their sensitivity. Therefore searches for new millisecond pulsars are absolutely essential to the detection of gravitational waves from merging galaxies. I will review the status of current pulsar search efforts and how they have contributed to PTAs. I will then present some of the recent highlights of the PALFA survey. Using the PALFA survey as a case study, I will outline the current challenges faced by pulsar searches, including RFI and a large number of false positives, and potential solutions to those issues.

    AGILE is a scientific mission of the Italian Space Agency (ASI) with INFN, INAF e CIFS participation, devoted to gamma-ray astrophysics. The satellite is in orbit since April 23rd, 2007. Gamma-ray astrophysics above 100 MeV is an exciting field of astronomical sciences that has received a strong impulse in recent years. Despite the small size and budget, AGILE produced several important scientific results, among which the unexpected discovery of strong and rapid gamma-ray flares from the Crab Nebula. This discovery won to the AGILE PI and the AGILE Team the prestigious Bruno Rossi Prize for 2012, an international recognition in the field of high energy astrophysics. We present here the AGILE data center main activities, and we give an overview of the AGILE scientific highlights after 5 years of operations.

    It is widely accepted that stars do not form in isolation but result from the fragmentation of molecular clouds, which in turn leads to star cluster formation. Over time, clusters dissolve or are destroyed by interactions with molecular clouds or tidal stripping, and their members become part of the general field population. Star clusters are thus among the basic building blocks of galaxies. In turn, star cluster populations, from young associations and open clusters to old globulars, are powerful tracers of the formation, assembly, and evolutionary history of their parent galaxies. Although their importance (e.g., in mapping out the Milky Way) had been recognised for decades, major progress in this area has only become possible in recent years, both for Galactic and extragalactic cluster populations. Star clusters are the observational foundation for stellar astrophysics and evolution, provide essential tracers of galactic structure, and are unique stellar dynamical environments. Star formation, stellar structure, stellar evolution, and stellar nucleosynthesis continue to benefit and improve tremendously from the study of these systems. Additionally, fundamental quantities such as the initial mass function can be successfully derived from modelling either the Hertzsprung-Russell diagrams or the integrated velocity structures of, respectively, resolved and unresolved clusters and cluster populations. Star cluster studies thus span the fields of Galactic and extragalactic astrophysics, while heavily affecting our detailed understanding of the process of star formation in dense environments. This report highlights science results of the last decade in the major fields covered by IAU Commission 37: Star clusters and associations.

    This issue of Toxicological Sciences features several exciting changes: a redesigned cover, revised category subheadings, and this “Look Inside ToxSci” feature. Together with my esteemed colleagues in the field of green chemistry, we have outlined some exciting opportunities for the field of toxicology in the editorial on green chemistry and toxicology. There are insightful articles on the regulatory challenges regarding mixtures that are being addressed by the European Union and on risk assessment of carbon nanotubes. In the past, we have highlighted a single article from each issue. It has become increasingly difficult to select just one article from the volume of high quality work, so beginning this month we will highlight multiple articles in each issue here in “Look Inside ToxSci.” From solvents, pesticides, and nanoparticles to the microbiome, the highlighted articles span the breadth of our field. Of course, this issue contains something that will never change; our raison d'etre …the best original research in the field of toxicology. —Gary W. Miller PMID:25232149
