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.

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

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.

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.

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.

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

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 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.

The development of ophthalmology to its present level of sophisticated practice is an extraordinary story of research, experiment, and achievement. Dates in Ophthalmology: A Chronological Record of Progress in Ophthalmology over the Last Millennium charts the progress of that achievement over the last millennium, highlighting and describing the key dates of advancement. It presents a concise listing of the chief personages, periods, publications, and events in the history of ophthalmology from ancient times to the present. The book demonstrates how ideas, discoveries, and technologies cross borders and oceans. It illustrates the interplay of subspecialties, the changing pre-eminence of countries and cities, and the explosions of creativity and generations of dormancy in various areas. The author highlights the numerous and diverse events and people responsible for shaping this specialty. There are many ways of looking at history: from the standpoint of the lives of major figures, of society and impact, of subspecialties, of countries, of institutions, and of books. By presenting its information chronologically, Dates in Ophthalmology explores the how these areas intersect, influence, and impact each other.

Studies on Retinal and Choroidal Disorders examines the role that oxidative and nitrosative stress plays in the complex physiology and pathophysiology of the retina and choroid. Both the basic science researcher and the clinical practitioner can use this book as a guide to the current understanding of retinal and choroidal cellular mechanisms involved in aging and disease. Beginning with a review of oxidative stress and inflammation in the pathoetiology of AMD and a review of the complement system in the retina, the book then takes a detailed look at oxidative stress in lipid metabolism and oxidized lipoproteins in the retina. It examines the anti-apoptotic activity of -crystallins in the presence of glutathione, oxidative stress in the mitochondria and endoplasmic reticulum, the role of iron in retinal disease, the mechanisms of pathological VEGF expression, NAPDH oxidase mechanisms, and Hepatocyte Growth Factor in oxidative stress in the retina. A detailed look at the Ccl2-/-/Cx3cr1-/- mouse model of AMD follows. Then a detailed examination of the systemic changes in AMD is followed by a discussion of cerium oxide nanoparticle reduction of oxidative stress. Two chapters discuss progenitor cells in the cause and treatment of retinal diseases including AMD and diabetic retinopathy. Natural compounds in the prevention and treatment of retinal diseases are exhaustively presented, followed by a chapter on serotonin 5-HT1A receptor agonists in oxidative stress of the retina. The current anti-VEGF treatment strategies of neovascular AMD are then given. The volume continues with a detailed look at nitric oxide and inducible nitric oxide synthase in retinal vascular disease, an explanation of an in vivo technique of studying the effect of lipid hydroperoxides on circulating leucocytes in the retina, an excellent review of oxidative stress in retinopathy of prematurity, and a look at VEGF induced oxidative stress in the retinal ganglion cell. The book ends with a detail examination of the role of carotenoids in retinal health and disease. These 31 chapters summarize what is known about oxidative stress in retinal and choroidal disorders. All those involved with degenerative diseases of the eye will find Studies on Retinal and Choroidal Disorders to be illuminating and comprehensive.

Just as neuro-ophthalmology links ophthalmology with other medical specialties, so too the optic nerve links the eye with the central nervous system. Thus, ophthalmologists must be familiar with a wide variety of optic nerve diseases, which may occur in isolation or form part of a generalised neurologic or systemic disorder. Optic Nerve Disorders is an up-to-date guide to the relevant literature on a wide variety of clinical diseases of the optic nerve that will give the clinician a handy reference to assist in both their diagnosis and management. It provides a succinct, yet comprehensive review of optic nerve disorders commonly encountered in clinical practice, briefly reviews the anatomy and physiology of the optic nerve, and outlines those techniques of particular importance during clinical testing of optic nerve function. Chapter 1 reviews the major anatomic aspects of the optic nerve at both a macroscopic and a microscopic level, and discusses the critical role of axonal transport in optic nerve physiology. Chapter 2 takes the reader back to basics, emphasising the importance of obtaining a detailed patient history and performing a careful ophthalmologic examination. Chapters 3 through 9 cover the major clinical disorders affecting the optic nerve: papilledema, optic neuritis, ischemic optic neuropathy, compression of the anterior visual pathways, developmental and hereditary optic nerve disorders, toxic and nutritional optic neuropathy, and traumatic optic neuropathy. The last chapter, Chapter 10, summarises those optic neuropathies that cannot easily be categorised, but that frequently confront the general ophthalmologist in clinical practice.

This first volume of the series Essentials in Ophthalmology aims to give a picture of recent progress in the field of glaucoma, in both basic clinical research and applied clinical science. Its intention is not to replace textbooks on glaucoma, but to serve as a conceptual bridge between original research and textbook presentation. The volume encompasses (a) genetic aspects of different forms of glaucoma, such as normal tension glaucoma, pseudoexfoliative glaucoma, childhood glaucoma, and angle closure glaucoma, (b) methods of diagnosis, such as imaging techniques, visual fields, electrophysiology, and ultrasound biomicroscopy, and (c) aspects of therapy, such as the target pressure concept, wound modulation in glaucoma surgery, neuroprotection, treatment of normal tension glaucoma, and the evaluation of nonpenetrating surgery. The editors have set out to provide the reader with a diversity of interesting topics reflective of the evidence-based, modern approach to the field of glaucoma. Written for: Ophthalmologists in clinical and private practice, residents, ophthalmologists-in-training as well as optometrists and ophthalmic nurses
