Download or read book Electroretinograms written by Gregor Belusic and published by BoD – Books on Demand. This book was released on 2011-08-09 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2006-04-07 with total page 1033 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Handbook of Clinical Electrophysiology of Vision by : Minzhong Yu
Download or read book Handbook of Clinical Electrophysiology of Vision written by Minzhong Yu and published by Springer Nature. This book was released on 2019-12-26 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Electrodiagnosis of Retinal Disease by : Yozo Miyake
Download or read book Electrodiagnosis of Retinal Disease written by Yozo Miyake and published by Springer Science & Business Media. This book was released on 2006-03-28 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Book Synopsis An Analysis of the D.c. Component of the Local Electroretinogram in the Intact Eye of the Cat by : Roy Herbert Steinberg
Download or read book An Analysis of the D.c. Component of the Local Electroretinogram in the Intact Eye of the Cat written by Roy Herbert Steinberg and published by . This book was released on 1967 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The local electroretinogram (LERG) was recorded with microelectrodes from the intact eye in response to focused spots and annuli delivered by a dual-beam ophthalmoscope. The d.c. component was readily isolated from the b-wave on the basis of a lower threshold, smaller summation area, and greater resistance to light adaptation, thereby supporting a hypothesis that separates these components. At high flash intensities the d.c. component increased in duration as its decay was delayed; a slowing in decay rate also occurred and an earlier off-response was revealed. These effects were influenced by flash duration and the level of light adaptation. The late receptor potential was also recorded from the area centralis after clamping the retinal circulation at the optic disk. At moderate levels of light adaptation it was isolated from the c-wave and exhibited a rapid decay-phase. The behavior of the late RP in response to increases in flash intensity and duration paralled the behavior of the d.c. component. (Author).
