Electroretinography (ERG) is a non-invasive electrophysiological method which provides objective information about the function of the retina. Advanced ERG allows to assay the different types of retinal receptors and neurons in human and animal models. This book presents contributions on the recent state of the ERG. The book is divided into three parts. The first, methodological part, reviews standard methods and normatives of human ERG, reports about the advanced spatial, temporal and spectral methods of stimulation in human ERG, and deals with the analysis of the multifocal ERG signal. The second part deals with the ERG in different diseases of the human visual system and in diabetes. The third part presents the ERG in the standard animal models of human retinal disease: mouse, rat, macaque and fruitfly.

The long-awaited second edition of an authoritative reference on electrophysiologic vision testing, including detailed information on techniques and problems, basic physiology and anatomy, theoretical concepts, and clinical findings; with extensive new material. This authoritative text is the only comprehensive reference available on electrophysiologic vision testing, offering both practical information on techniques and problems as well as basic physiology and anatomy, theoretical concepts, and clinical correlations. The second edition, of the widely used text, offers extensive new material and updated information: 65 of the 84 chapters are completely new, with the changes reflecting recent advances in the field. The book will continue to be an essential resource for practitioners and scholars from a range of disciplines within vision science. The contributions not only cover new information—important material that is likely to become more important in the next decade—but also offer a long-range perspective on the field and its remarkable development in the last century. After discussing the history and background of clinical electrophysiology, the book introduces the anatomy of the retina and principles of cell biology in the visual pathways at the molecular, physiological, and biochemical levels. It relates these new findings to the techniques and interpretations of clinical tests, including the electro-oculogram (EOG), electroretinogram (ERG), and visual evoked potentials (VEP), which are discussed in detail, as are equipment, data acquisition and analysis, principles and protocols for clinical testing, diseases and dysfunction, and animal testing. Notable additions for this edition include chapters on the origin of electroretinogram waveforms, multifocal techniques, testing in standard laboratory animals, recent advances in analysis of abnormalities in disease, and the applications of these techniques to the study of genetic abnormalities.

This book provides an analytical and thorough review of clinical electrophysiology of vision, and the progress made in the field in the past decade. Handbook of Clinical Electrophysiology of Vision is designed to aid the readers in understanding the types of electrophysiologic tests that should be used in specific diseases, how to explain the results of these exams, and how to perform the tests of clinical electrophysiology of vision. Concise in format, the Handbook of Clinical Electrophysiology of Vision is divided into two sections that discuss a wide range of relevant topics, such as technology of electroretinography, electrooculography, visual evoked potential, characteristics of electroretinography in retinal diseases, and the characteristics of optic nerve diseases. Part one begins with a discussion on the basic theory of electrophysiology of vision, illustrating physiologic sources of electrophysiological responses, the techniques of the recording, and analysis of electrophysiologic signals. Part two then dives into the clinical application of electrophysiology of vision, and subsequently summarizes the characteristics of the electrophysiological signals in a number of disorders of retina and optic nerve. Written by experts in the field, Handbook of Clinical Electrophysiology of Vision is an invaluable resource for ophthalmologists, optometrists, electrophysiologists, residents, fellows, researchers, technicians and students in ophthalmology, optometry and vision science.

Soon it will be time for me to retire from my position as professor of o- thalmology in the Department of Ophthalmology, Nagoya University School of Medicine. I have therefore decided to summarize my expe- ence of more than 30 years of studies on the clinical electrophysiology of vision. These studies were performed in our department through the hard work and good ideas of many co-workers,and the chapters of this book cover the rationale and results of our studies. Because excellent textbooks on clinical electroretinography already exist, my wish is not to write another textbook; instead,this book is in the form of essays that include my beliefs and philosophy on the clinical electrophysiology of vision. As such,this book does not include every clinical disease but only those that we have identi?ed or studied in detail. In addition to full-?eld electroretinography (ERG),we developed the techniques and instrumentation to record focal macular ERG more than two decades ago. Using these techniques, we were able to determine several new physiological properties of the normal macula, many new pathophysiological mechanisms of known diseases,and some new cli- cal entities with unique functional properties. Fortunately,the recent advances of macular surgery and imaging are such that the macular con?guration can easily be determined. During the process of surgery,we have obtained considerable information on the c- relation of macular function and macular morphology using focal macular ERGs and optical coherence tomography (OCT).

​This book provides the ophthalmologist with the most recently available data on the macular dystrophies, a group of many different inherited or sporadic eye conditions linked by a problem with photoreceptors or other structures of the central retina. Internationally recognized experts in the field present the latest evidence and discuss their own personal experiences with regard to each of the principal dystrophies as well as some very rare entities. Topics covered include molecular biology, state-of-the-art diagnostic techniques, and the newest treatment options, including still experimental therapies. Attention is also devoted to a range of issues that continue to be debated. The editors have taken care to ensure that chapters are of a uniformly high standard while not sacrificing the originality of the individual authors. Macular Dystrophies will fully acquaint the reader with both the latest research findings and the current and emerging approaches to diagnosis and treatment.
