Vascular diseases of the retina are a major cause of blindness among all age groups. Edited and written by internationally well-known experts, this state-of-the-art comprehensive overview of basic and clinical science will enhance the understanding of retinal vascular disease and help in the evaluation of current and future treatment approaches for the clinician. The well-structured and highly illustrated text is divided into three easy-to-follow sections. This unique textbook-atlas also includes topics which are not currently found in other retinal disease textbooks, such as case reports and clinical follow-ups.

The Seventh International Visual Field Symposium organized by the Interna tional Perimetric Society was held in Amsterdam, The Netherlands, September 6-10,1986. In many respects it was an exciting and fruitful meeting. The number of participants was greater than ever. The number of papers was too great to accommodate all of them. The quality of the papers reflects the continuously rising interest in perimetry in general and in automated perimetry in particular. Last but not least the social programme was organized in the, by now, almost classical friendly, enjoyable and humouristic style of the International Perimetric Society. This created an atmosphere of openness and free exchange of informa tion whICh was clearly also felt in the scientific sessions. The scientific part was divided in seven sessions with 44 spoken papers and a separate postersession during which the 46 posters were discussed. The major themes of the meeting were 'The influence of media-disturbances on the visual field' and 'Advances in perimetry in glaucoma with special emphasis on pro gression'. The session on 'media' provided interesting information on how the visual field was effected by preretinal filters. The authors either studied the influence of lens or corneal opacities or simulated opacities by special filters placed in front of the eye. In two papers the effect of cataract was qualified by photography or stray light measurements."

Affecting over a hundred million individuals worldwide, retinal diseases are among the leading causes of irreversible visual impairment and blindness, and appropriate study models, especially animal models, are essential to furthering our understanding of the etiology, pathology, and progression of these endemic diseases. In Animal Models for Retinal Diseases, recognized experts in the field highlight valuable techniques as well as animal models for the prominent retinal diseases in order to aid in the evaluation, development, and improvement of therapeutic strategies. Beginning with an overview of the morphology of the retina, visual behavior, and genetics and genomics approaches for retinal research, the book continues by covering animal models for the research of specific human retinal diseases, e.g., retinal degeneration, age-related macular degeneration, retinopathy of prematurity, diabetic retinopathy, glaucoma, retinal ischemia, and retinal inflammation. As a volume in the successful Neuromethods series, the chapters provide authoritative reviews of the most commonly used approaches in the field. Vital and easy to use, Animal Models for Retinal Diseases serves to support the important future research of ocular investigators, ophthalmologists, and neuroscientists currently delving into this fascinating field of study.

Continuous regeneration of the cornea is necessary to maintain this tissue in the transparent state that is essential for vision. Therapy for repair of the damaged anterior cornea is currently addressed through the transplantation of donor corneas or the delivery of limbal epithelial stem cells (LESC) to the ocular surface using amniotic membrane (AM) as a supporting scaffold. Research on the bioengineering of corneal equivalents as replacement tissue is underway to develop viable corneal prosthetics. Corneal Regenerative Medicine: Methods and Protocols provides a concise overview of essential techniques in the field of corneal regenerative medicine, highlighting novel strategies to guide the management of key therapies within this area of medicine. Divided into four convenient sections, topics include the identification, characterisation and cultivation of LESC, as well as the investigation of biopolymers used as the basis for corneal substitutes. Written in the 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 protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Corneal Regenerative Medicine: Methods and Protocols covers the fundamental techniques useful for both the laboratory and clinical settings.

Uveitis and immunological disorders encompass a wide spectrum of potentially blinding diseases that are seen in daily practice by many ophthalmologists. In recent years enormous progress has been made understanding the principal mechanisms of inflammatory and immunological processes in ocular disorders. The purpose of this volume of Essentials in Ophthalmology is to provide the ophthalmologist with our present understanding of the pathogenesis of the most frequent immune-mediated disorders of the eye and a practical approach to these diseases.

Uveitis and Immunological Disorders fits in the series of Essentials in Ophthalmology to fill the gap between textbooks and original research publications. With a broad spectrum of contributions, including diseases affecting the conjunctiva, sclera and cornea as well as intraocular inflammation, this publication will serve not only as a valuable source of up-to-date information for ophthalmologists but also be of interest to pediatricians, specialists in internal medicine and dermatologists confronted with inflammatory eye diseases. Although mainly focused on clinical aspects of inflammatory eye diseases, several contributions address aspects such as immune mechanisms and genetics of these diseases.

Unlike the cornea or lens, the retina is part of the central nervous system and cannot be replaced. Therefore degeneration of the outer retina is blinding, but trials using devices such as retinal implants which combine biology with technology are showing promise at restoring vision. Macular diseases are the most common cause of blindness in the developed countries. Oedema of the macula may arise in the retina, such as in diabetes mellitus or in epiretinal membrane formation, but most importantly it is age-related insufficiency of the underlying retinal pigment epithelial cell that causes central scotoma.

This volume on vitreoretinal surgery is written by authors who are leaders in these fields of research. It covers the large body of experimental research performed to date on the most urgent clinical problems of vitreoretinal disease. Topics dealt with in the book include:

Methods against etinal Exudation by Thermal Laser

Replacement of the Diseased Retinal Pigment Epithelial (RPE) Cell

Secondary Wound Healing after Retinal Attachment (Proliferative Vitreoretinopathy, PVR)

Adjunct Pharmacotherapy

Heavier than Water Vitreous Substitutes

Conditions Associated with a High Risk of PVR (e.g. Giant Tear Retinal Detachments)

Uveitis Vitrectomy with New Diagnostic and Therapeutic Means

The area of spinal cord plasticity has become a very actively researched field. The spinal cord has long been known to organize reflex patterns and serve as the major transmission pathway for sensory and motor nerve impulses. However, the role of the spinal cord in information processing and in experience driven alterations is generally not recognized. With recent advances in neural recording techniques, behavioral technologies and neural tracing and imaging methods has come the ability to better assess the role of the spinal cord in behavioral control and alteration. The discoveries in recent years have been revolutionary. Alterations due to nociceptive inputs, simple learning paradigms and repetitive inputs have now been documented and their mechanisms are being elucidated. These findings have important clinical implications. The development of pathological pain after a spinal cord injury likely depends on the sensitization of neurons within the spinal cord. The capacity of the spinal cord to change as a function of experience, and adapt to new environmental relations, also affects the recovery locomotive function after a spinal cord injury. Mechanisms within the spinal cord can support stepping and the capacity for this behavior depends on behavioral training. By taking advantage of the plasticity inherent within the spinal cord, rehabilitative procedures may foster the recovery of function.

Inside this book are reflections on the nature of vision and blindness. Further, there are explorations of interpretive research, and presentations of some seminal and contemporary publications in the field of blindness. The other major fodder for conversation with you the reader is an elaborated example of empirical research entitled Blind Online Learners. Each element of this inquiry is explicitly reflected upon as an example of interpretive research. This book is intended for four intersecting groups of readers. If you are a philosopher, closet or sanctioned, then you cannot ponder the nature of being without due consideration for vision, and cannot contemplate the role of seeing in our lives without listening to the stories of those who are blind. The tales within this text are particularly contemporaneous because they are contextualized by the cyber-phenomena of online learning. This segues to the second group of readers, as the described empirical research was originally intended to bring greater depth and breadth of understanding to the field of educational technology, particularly as it intersects with disability studies. There is a paucity of published literature that has inquired into disabled online learners, and this research study responds to that call. Third, this book may be used as a textbook on approaches to interpretive empirical research. It is as close as one may come to a recipe, walking students through a specific example. Because it is situated in actual empirical research, the intention was that it avoid the trap of being prescriptive or formulaic. Finally, the text is intended for readers interested in the field of blindness. The text reviews some of the seminal and contemporary research on blindness, and then presents an elaborated example of what we can and should expect to emerge in the knowledge production industry, changing what it means to be blind.

This volume of Documenta Ophthalmologica Proceedings Series collects the scientific papers presented at the 2nd International Symposium on Retinal Pigment Epithelium and the 4th Meeting of the European Macula Group held in Genoa, May 29-June 1, 1996. The Symposium on Retinal Pigment Epithelium was promoted by the University Eye Clinic of Genoa as the natural continuation of the first Symposium held with great success in Genoa in 1988. The previous Meetings of the European Macula Group were held in Coimbra (1988), Crete (1989) and Athens (1994). I was greatly pleased and honoured to host the fourth congress of this distinguished Society and I am grateful to Gabriel Coscas, Jose Cunha-Vaz and George Theodossiadis, found ers of the Society, for selecting Genoa on this occasion. The two meetings integrated well in an unicuum and brought together an exceptional number of outstanding retinal specialists coming from all over the world. All the aspects of the current research concerning retinal pigment epithelial and macular diseases were covered. Several interesting presentations regarded new techniques of retinal and choroidal imaging. A full session was dedicated to the latest advances in culture and transplantation of retinal pigment epithelial cells. Age-related macular degeneration was a major subject for discussion, including new approaches to treatment. This topic was high lighted by a mini-symposium on drusen, including a series of superb lectures on classification, clinicopathological studies, indocyanine green imaging, and laser treatment for prevention of choroidal neovascularization."

This timely publication fills a large gap in the ophthalmic literature which has so far lacked a monograph on the clinically very important subject of macular edema. The book presents the most up-to-date scientific concepts concerning the etiology and pathogenesis of blood retinal barrier breakdown such as tight junction associated protein dysfunction, and changes in fluid transport properties of the retinal pigment epithelium. The bulk of the book is clinically oriented and addresses novel imaging and diagnostic techniques for the detection of macular edema as well as the clinical context of a panoply of ocular diseases which induce macular edema, such as diabetes, other vasculopathies, uveitis, and many others. New light is shed on the association between highly active antiretroviral therapy and the induction of macular edema in HIV-positive patients. Novel drug treatment regimens with steroids and carbonic anhydrase inhibitors as well as new ways of applying laser and surgical therapies are also discussed in detail, and practical treatment guidelines are given. This book will be helpful for vitreoretinal specialists as well as for the practising ophthalmologist confronted with patients suffering from macular edema.

Foundations of Low Vision: Clinical and Functional Perspectives, the ground-breaking text that highlighted the importance of focusing on the functional as well as the clinical implications of low vision, has been completely updated and expanded in this second edition. The revised edition goes even further in its presentation of how best to assess and support both children and adults with low vision and plan programs and services that optimize their functional vision and ability to lead productive and satisfying lives, based on individuals' actual abilities. Part 1, Personal and Professional Perspectives, provides the foundations of this approach, with chapters focused on the anatomy of the eye, medical causes of visual impairment, optics and low vision devices, and clinical low vision services, as well as psychological and social implications of low vision and the history of the field. Part 2 focuses on children and youths, providing detailed treatment of functional vision assessment, instruction, use of low vision devices, orientation and mobility, and assistive technology. Part 3 presents rehabilitation and employment issues for working-age adults and special considerations for older adults.

As a garden is to a gardener, so a book is to its author. Nurtured out of love, both are a source of pride and hope. Microbiology, immunol ogy, infectious diseases, rheumatology, and ophthalmology are the seeds of this textbook on uveitis. Over the years, these branches of medicine have been cultivated and garnered to care for patients with inflammatory diseases of the eye, a most hardy species in the family of ocular maladies. The aim of this clinical manual is to give both a serviceable frame work and practical information on ocular inflammatory disease. The first section is devoted to general principles and commonly held sup positions in the field of uveitis. A system of diagnosis, based on the differential, is also offered. Traumatic uveitis is addressed in the sec ond section. The third part examines infectious diseases that have been identified with uveitis. These are frequently curable forms of ocular inflammation caused by replicating foreign antigens. The fourth section of this textbook considers inflammatory diseases of the eye with a presumed autoimmune mechanism. A disobedient, autoreactive immune response is postulated to playa role in these forms of uveitis. Masquerade and idiopathic conditions are dis cussed in the final chapters. Etiology, epidemiology, pathogenesis, clinical presentation, diagnosis, differential diagnosis, treatment, and prognosis are provided for each disease syndrome. As with most gardens, there are many styles and delightful entrances to the field of uveitis.

This book describes advances in implantable neural stimulation technology to restore partial sight to people who are blind from retinal degnerative diseases such as age-related macular degeneration and retintis pigmentosa. Many scientific, engineering, and surgical challenges must be surmounted before widespread practical applications can be realized. The book summarizes the state of research and clinical practice in the field and reviews the current ideas and approaches of its leading researchers and practitioners.

Thirty years ago, Gobin and Bierlaagh developed the simultaneous horizontal and cyclovertical strabismus surgery that became a recognized, albeit much debated method, but no manual on the subject was available until now. The book is aimed at ophthalmologists interested in strabismus. It is also intended for orthoptists, in view of the importance of examining ocular motility. Although the ophthalmologist remains responsible for the surgical indication, the active participation of the orthoptist is advantageous. The analysis of incomitances of the eye movements is discussed extensively, as it is the keystone of simultaneous surgery. For the same reason, great attention is given to the surgical indications. The chapter on oculomotor disturbances is completed with a series of examples of the most common motility disorders and the indications for their surgical treatment. Surgery is covered in detail. Primary surgery is discussed in the same section as surgery for under and overcorrection.Since a correct sequence of the different surgical acts is essential for a smooth intervention, the technique of operating rectus as well as oblique muscles is presented in a clear, step-by-step manner. The last chapter deals with the complications such as limitation of duction, postoperative diplopia and the change in palpebral fissure. The book contains approximately 380 black and white illustrations in 270 figures and 94 colour plates, illustrating surgical techniques. The work is based on an analysis of more than 6500 cases.

Since its inception, the International Research Group on Colour Vision Deficiencies (IRGCVD) has followed the policy that the Symposium Pro ceedings should be as close as possible to a complete record of the scientific content of the meeting. This policy has the advantage of providing an accurate picture of the current state of the art in research on color vision deficiencies, but it also has the disadvantage that papers typically span a wide range of quality. In this volume, however, we have instituted a system of peer review in an effort to enhance scientific quality as much as possible while continuing our past policy of publishing all submitted manuscripts. In addition to being edited for English composition and grammar, each of the papers included here has been carefully reviewed by an IRGCVD member selected for his or her expertise in the specific topic of the paper. Reviewers were instructed to include in their comments suggestions for improvement rather than recom or rejection. In our opinion, this review process mendations for publication has resulted in substantial improvement of many of the articles and has enhanced the value of the publication. We are pleased to acknowledge the efforts of our reviewers and offer them our sincere thanks for their important contributions to Colour Vision Deficiencies X. The Editors B. Drum, J. D.
