This detailed volume introduces the reader to current methods in glaucoma research, in particular those that make use of animal disease models. Given that the retinal ganglion cells damaged and destroyed by glaucoma do not regenerate after lowering the intraocular pressure, new therapeutic approaches that protect ganglion cells directly is a vital research goal that this volume's contents aim to aid scientists in developing. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Glaucoma: Methods and Protocols serves as a useful guide for both ophthalmologists in clinical practice and researchers in the field.

Named after the pioneering Scottish ophthalmologist, Sir Stewart Duke-Elder, this exam is intended for medical students who have completed their ophthalmology undergraduate teaching, but it is open to all medical undergraduates provided they have not graduated at the time of the examination. Students may take the examination on more than one occasion provided they have not yet graduated and have not previously won the prize. The exam is a notoriously competitive and difficult exam to sit during medical school. Each year students can register for the exam before December and the exam is held in early March. Two hours are allocated to answer ninety multiple choice questions. The standard of some questions that students encounter is beyond those of the undergraduate ophthalmology curriculum experienced during medical school. It consists of questions from the different sub-specialties within ophthalmology (Eye News). Sponsored by the Royal College of Ophthalmologists, the candidate gaining the highest mark will be offered to chance to visit St John's Eye Hospital in Jerusalem. The winning candidate can alternatively choose a cash prize of GBP400. Although not a mandatory part of ophthalmology training, students are encouraged to take the exam as a pass gives a credit on the CV and also gains points towards an ST1 interview. It is also good practice in preparation for other exams. Compiled by authors who have all passed the Duke Elder examination, this book presents 180 multiple choice questions and answers with clear and in depth explanations. The first section provides a structured practice paper sectioned out by topic to assist revision, and the second section consists of a full unstructured mock exam. Questions have been written specifically with the Duke Elder exam in mind, making this book an invaluable revision aid to help achieve success in the examination.

Proceedings of the 19th ISCEV Symposium, Horgen-Zurich, Switzerland, June 1-5, 1981

Vision and the Visual System offers students, teachers, and researchers a rigorous, yet accessible account of how the brain analyzes the visual scene. Schiller and Tehovnik describe key aspects of visual perception while explaining the relationship between eye movements and the neural structures in the brain, which play a central role in how we process visual information. The book discusses various brain areas involved in processing information, focusing on the evolutionary origins and mechanics behind the several parallel pathways that compose the visual system. Later chapters explain how the nervous system processes the perception of color, motion, depth, and patterns. A variety of illusions are on display in Chapter 14, where the authors provide detailed explanations that deconstruct how the visual system operates to create them. The volume concludes with a discussion of recent attempts to build visual prosthetic devices for blind individuals, of which there are more than 40 million in the world. Vision and the Visual System is based on Professor Schiller's more than 40 years of experience teaching vision courses at MIT, and is tailored especially for college undergraduates and graduate students interested in visual perception and the operations of the visual system.

Optical Coherence Tomography represents the ultimate noninvasive ocular imaging technique although being in the field for over two-decades. This book encompasses both medical and technical developments and recent achievements. Here, the authors cover the field of application from the anterior to the posterior ocular segments (Part I) and present a comprehensive review on the development of OCT. Important developments towards clinical applications are covered in Part II, ranging from the adaptive optics to the integration on a slit-lamp, and passing through new structural and functional information extraction from OCT data. The book is intended to be informative, coherent and comprehensive for both the medical and technical communities and aims at easing the communication between the two fields and bridging the gap between the two scientific communities.

Proceedings of a Workshop held at the Scuola Normale Superiore, Pisa, Italy on December 12-15, 1980

This book will contain the proceedings of the XV International Symposium on Retinal Degeneration (RD2012). A majority of those who will speak and present posters at the meeting will contribute to this volume. The blinding diseases of inherited retinal degenerations have no treatments, and age-related macular degeneration has no cures, despite the fact that it is an epidemic among the elderly, with 1 in 3-4 affected by the age of 70. The RD Symposium will focus on the exciting new developments aimed at understanding these diseases and providing therapies for them. Since most major scientists in the field of retinal degenerations attend the biennial RD Symposia, they are known by most as the "best" and "most important" meetings in the field. The volume will present representative state-of-the-art research in almost all areas of retinal degenerations, ranging from cytopathologic, physiologic, diagnostic and clinical aspects; animal models; mechanisms of cell death; candidate genes, cloning, mapping and other aspects of molecular genetics; and developing potential therapeutic measures such as gene therapy and neuroprotective agents for potential pharmaceutical therapy. While advances in these areas of retinal degenerations will be described, there will be many new topics that either were in their infancy or did not exist at the time of the last RD Symposium, RD2010. These include the role of inflammation and immunity, as well as other basic mechanisms, in age-related macular degeneration, several new aspects of gene therapy, and revolutionary new imaging and functional testing that will have a huge impact on the diagnosis and following the course of retinal degenerations, as well as to provide new quantitative endpoints for clinical trials. The retina is an approachable part of the central nervous system (CNS), and there is a major interest in neuroprotective and gene therapy for CNS diseases and neurodegenerations, in general. It should be noted that with successful and exciting initial clinical trials in neuroprotective and gene therapy, including the restoration of sight in blind children, the retinal degeneration therapies are leading the way towards new therapeutic measures for neurodegenerations of the CNS. Many of the successes recently reported in these areas of retinal degeneration sprang from collaborations established at previous RD Symposia, and many of those will be reported at the RD2010 meeting and included in the proposed volume. We anticipate the excitement of those working in the field and those afflicted with retinal degenerations will be reflected in the volume.

This book presents a new method for analyzing the structure and function of the biological branching systems of fractal trees, with a focus on microcirculation. Branching systems in humans (vascular and bronchial trees) and those in the natural world (plants, trees, and rivers) are characterized by a fractal nature. To date, fractal studies have tended to concentrate on fractal dimensions, which quantify the complexity of objects, but the applications for practical use have remained largely unexplored. This book breaks new ground with topics that include the human retinal microcirculatory network, oxygen consumption by vascular walls, the F hraeus-Lindqvist effect, the bifurcation exponent, and the asymmetrical microvascular network. Readers are provided with simple formulas to express functions and a simulation graph with in vivo data. The book also discusses the mechanisms regulating blood flow and pressure and how they are related to pathological changes in the human body. Researchers and clinicians alike will find valuable new insights in these pioneering studies.

This book provides an integrated review of the human ocular microbiome. It documents the discovery of ocular surface microbes by the conventional cultivable method and next generation sequencing technologies in both healthy and diseased (keratitis, uveitis, endophthalmitis, blepharitis, conjunctivitis etc.) eyes. The book further discusses the confounding factors that influence the microbiome, mycobiome and virome. The chapters cover niche-specificity with reference to skin, eyelid- margin, hands etc. It highlights the concept of core genera, dysbiosis and discriminating genera and covers the functional relevance of the dysbiotic microbiome, mycobiome and virome with respect to ocular diseases. The book includes topics on the relevance of molecular mechanisms, including quorum-sensing and mucin metabolism to ocular disorders, such as dry eye; and, microbiome-based therapies for treating of ocular disorders like vernal keratoconjunctivitis. The book is essential for microbiologists studying the human eye, ophthalmologists treating eye infection and trauma. It also caters to students of medical microbiology and medicine.

This book contains unique cases from Middle Eastern patients that are very rare in other countries and cases not included in other literature on this topic.

The book collects over 600 pictures of different corneal ulcers/keratitis, including before and after treatment photos over 10 years of practice. The photos regarding corneal ulcers caused by specific and isolated microorganisms with before and after treatment photos will give a comprehensive idea to any clinician how the appearance of the eye will be by the end. This book will include some surgical cases with almost all possible complications as well as corneal tattooing and Boston type 1 keratoprosthesis cases. It will be an ideal reference source for ophthalmologists, residents, and students.

This volume represents the proceedings of the Fifth Congress of the International Society of Ocular Toxicology (ISOT), which was held at the Grove Park Inn and Resort in Asheville, North Carolina, October 13-17, 1996. We are delighted to present this volume to the ophthalmic community, especially those with a significant interest in ocular toxicol ogy. The Fifth Congress was developed around themes relating to ocular drug metabolism, the ocular pathophysiological effects of nitric oxide, government issues relating to the use of alternative methods for toxicity testing, and a workshop that encompassed comparisons of both in vitro versus in vivo models as well as different animal models. The outcome of this congress, embodied in this volume, is a contribution to the methodologies currently employed or under development and to various drug or physical effects on different ocular tissues. While the focus of this proceedings is on ocular effects of drugs or other materials, many of the contributions deal with topics that have a much broader interest. The workshop concerning the use of different model systems and the choice of the best animal model for drug testing covers a wide range of interests that ex tends far beyond specific ocular effects. This is especially true in the area of alternative methods and in the choice of the best animal model for examination of different disease entities.
