Inherited And Acquired Colour Vision Deficiencies

An introduction to the theory and practice of optometry in one succinct volume. From the fundamental science of vision to clinical techniques and the management of common ocular conditions, this book encompasses the essence of contemporary optometric practice. Now in full colour and featuring over 400 new illustrations, this popular text which will appeal to both students and practitioners wishing to keep up to date has been revised significantly. The new edition incorporates recent advances in technology and a complete overview of clinical procedures to improve and update everyday patient care. Contributions from well-known international experts deliver a broad perspective and understanding of current optometric practice. A useful aid for students and the newly qualified practitioner, while providing a rapid reference guide for the more experienced clinician. Comprehensive and logical coverage detailing the full spectrum of optometric practice in one volume. Succinctly covers the basics of anatomy, physiology, pharmacology, investigative techniques and clinical management of common eye conditions to provide key topics likely to be met in clinical practice. Discusses the full range of refractive correction, from spectacles and contact lenses to surgical treatment. Includes chapters on the management of special populations, including paediatric, elderly, low vision and special needs patients. Heavily illustrated throughout with key diagrams and images to support the text. Complete restructuring of contents into three sections: basic sciences, clinical techniques and patient management. Full colour throughout with over 400 illustrations. Many new chapters reflecting the changes in optometric practice and technology over the last 20 years, including new imaging and diagnostic procedures and methods of ocular treatment and refractive correction. Now includes internationally renowned authors from around the world. Details a full range of refractive and management approaches for patient care.

Leading philosophers and scientists consider what conclusions about color can be drawn when the latest analytic tools are applied to the most sophisticated color science.Philosophers and scientists have long speculated about the nature of color. Atomists such as Democritus thought color to be "conventional," not real; Galileo and other key figures of the Scientific Revolution thought that it was an erroneous projection of our own sensations onto external objects. More recently, philosophers have enriched the debate about color by aligning the most advanced color science with the most sophisticated methods of analytical philosophy. In this volume, leading scientists and philosophers examine new problems with new analytic tools, considering such topics as the psychophysical measurement of color and its implications, the nature of color experience in both normal color-perceivers and the color blind, and questions that arise from what we now know about the neural processing of color information, color consciousness, and color language. Taken together, these papers point toward a complete restructuring of current orthodoxy concerning color experience and how it relates to objective reality. Kuehni, Jameson, Mausfeld, and Niederee discuss how the traditional framework of a three-dimensional color space and basic color terms is far too simple to capture the complexities of color experience. Clark and MacLeod discuss the difficulties of a materialist account of color experience. Churchland, Cohen, Matthen, and Westphal offer competing accounts of color ontology. Finally, Broackes and Byrne and Hilbert discuss the phenomenology of color blindness.Contributors Justin Broackes, Alex Byrne, Paul M. Churchland, Austen Clark, Jonathan Cohen, David R.

The 13th biennial Symposium of the International Research Group on Colour Vision Deficiencies was held from 27 July to 30 July, 1995, in the splendidjin de siecle Theatre Saint Louis, in Pau, France. A total of 80 papers and posters were presented during the four days, of which 56 have been selected for inclusion in this volume. Each has been reviewed by two of the Editors. Additionally, in numerous cases in which specialized knowledge was called for the Editors asked for external help; their assistance is acknowledged below. While Pau now exists largely on agriculture and, more recently, oil extraction and refining, a century ago it was a winter resort that rivalled Cannes and Nice; indeed, Baedeker judged the air of Pau to be preferable for those of a nervous disposition. Pau and the surrounding Beam district are rich in history and have close ties to the Basque region, both of which were exploited brilliantly by the local organizers, Doctors Jean and Veronique Lied, to introduce the partici pants to the gastronomy and traditions of the region. The Committee of the IRGCVD owe a great debt of gratitude to the external reviewers, Oscar Estevez, Karl Gegenfurtner, Gunilla Haegerstrom-Portnoy, RL. Hilz, John Krauskopf, Anne Kurtenbach, Barry B. Lee, Adam Reeves, Marilyn Schneck, L.T. Sharpe, Eugene Switkes, Wayne Verdon, and B.A.

From the 98 presentations of the XIIth Symposium on Colour Vision Deficiencies, 61 were selected after peer review and revision by the authors. In addition to these contributions this volume contains a cumulative index to all authors in the IRGCVD proceedings since the first one in 1968, including the present volume. The contents include contributions on basic questions of anatomical and electrophysiological organisation of the neural pathways underlying colour vision; and on ways in which disturbances of these pathways can produce acquired colour vision deficiencies. Further contributions deal with genetics and congenital red--green colour deficiencies and colour vision testing. The resulting publication contains much of interest to basic vision scientists as well as to specialists in colour vision deficiencies.
