When Dr. Katherine Tansley's "Vision in Vertebrates" appeared in 1965, it filled a real void that had hitherto existed. It did so by serving at once as a text-book: for an undergraduate course, a general introduction to the subject for post-graduate students embarking on research on some aspect of vision, and the interested non-specialists. Gordon Walls' "The Vertebrate Eye and It. s Adaptive Radiation" and A. Rochon-Duvigneaud's "Les Yeux et la Vision des Vertebres" have served as important sources of information on the subject and continue to do so even though it is 40 years since they appeared. However, they are essentially specialised reference works and are not easily accessible to boot. The genius of Katherine Tansley was to present in a succinct (132 pages) and lucid way a clear and an interesting survey of the matter. Everyone liked it, particularly the students because one could read it quickly and understand it. Thus, when it seemed that a new edition was desirable, especially in view of the enormous strides made and the vast literature that had accumulated in the past 20 years, one of us (MAA) asked Dr. Tansley if she would undertake the task. Since she is in retirement and her health not in a very satisfactory state both she and her son, John Lythgoe (himself a specialist of vision), asked us to take over the task.

There is perhaps no area of neuro-ophthalmology that is advancing more rapidly with respect to an understanding of its anatomy and physiology than the ocular motor system. For this reason, it is difficult not only to keep up with the latest information concerning the basic mechanisms involved in the control of eye movements but also to remain up to date regarding the pathophysiology of specific disorders of eye movement. The material in this book is derived from a two-day course on eye movements held in The Netherlands in 1986. The course was designed as an introduction to the normal ocular motor system and to disorders of eye movements and was aimed toward orthoptists, ophthalmolo gists, optometrists, neurologists, and neurosurgeons. The chapters in this book were compiled by a trio of experts in the field of eye movements and contain discussions of anatomy and physiology of the ocular motor system, techniques of examination of patients with diplopia, and pathophysiology of specific disorders of ocular motility. Many of the authors of these chapters are among the most active investigators of eye movements in the world today, and their comments thus reflect the latest information in the field. This text is both basic and com prehensive and thus has something for everyone, from the student just beginning a study of the ocular motor system to the seasoned 'veteran' who wishes to know the latest information regarding central ocular motor control mechanisms.

​*** OVER 13,000 COPIES SOLD *** While visiting an eyecare professional is essential, to make informed decisions, you need to understand what’s going on with your eyes. That’s why ​​Smart Medicine for Your Eyes ​​was written. Here is an A-to-Z guide to the most common eye disorders and their treatments, using both conventional and alternative care. This second edition has been designed to give you quick and easy access to up-to-date information and advice regarding the health of your eyes. Smart Medicine for Your Eyes is divided into three parts. Part One provides a simple overview of how the eyes work, describes the development of vision, and presents the basic history, theories, and practices of nutritional care, herbal therapy, and homeopathy. Part Two contains a comprehensive A-to-Z listing of the various eye disorders affecting children and adults, from nearsightedness to styes, from glaucoma to macular degeneration. Each entry clearly explains the problem and offers specific advice using a variety of approaches. Part Two also provides a troubleshooting guide that offers possible causes of common eye symptoms, a first-aid guide for eye emergencies, and a comprehensive table detailing ocular side effects that may be caused by today’s most popular systemic medications. Rounding out the book is Part Three, which presents step-by-step guidance on the specific techniques and procedures suggested in Part Two, including acupressure and acupuncture, eyeglasses and contact lenses, orthokeratology and refractive surgery, and vision therapy. Lists of recommended resource organizations and suppliers will help you put these suggestions into practice. A vital bridge between mainstream medicine and time-tested traditional therapies, Smart Medicine for Your Eyes is a reliable source of information that you will turn to time and time again to protect the greatest of your possessions—your eyes.

Physiology of the Eye, Fourth Edition reviews major advances in the physiology of the eye, including improvements in photochemical and electrophysiological techniques. In particular, the successful application of modern microelectrode techniques to the recording of activity at all stages in the visual pathway is considered. This edition is organized into four sections encompassing 23 chapters and begins with an overview of the anatomy of the eye and its vegetative physiology and biochemistry, paying particular attention to the aqueous humor and the intraocular pressure, the vitreous body, the cornea, and the lens. The discussion then shifts to the mechanism of vision, including its photochemical aspects and muscular mechanisms, and the neurophysiology of visual perception. Advances in electrophysiology of the receptors, and of the central nervous pathways of vision and eye movement, are examined along with the remarkable developments in separative techniques of the lens crystallins and the biochemical aspects of lens transparency. This book is a valuable resource for students and researchers in fields ranging from ocular science to physiology and biochemistry.

Originally published in 1981, this third volume deals with the empirical data base and the theories concerning visual perception – the set of mental responses to photic stimulation of the eyes. As the book develops, the plan was to present a general taxonomy of visual processes and phenomena. It was hoped that such a general perspective would help to bring some order to the extensive, but largely unorganized, research literature dealing with our immediate perceptual responses to visual stimuli at the time. The specific goal of this work was to provide a classification system that integrates and systematizes the data base of perceptual psychology into a comprehensive intellectual scheme by means of an eclectic, multi-level metatheory invoking several different kinds of explanation.

This book presents a collection of articles reflecting state-of-the-art research in visual perception, specifically concentrating on neural correlates of perception. Each section addresses one of the main topics in vision research today. Volume 1 Fundamentals of Vision: Low and Mid-Level Processes in Perception covers topics from receptive field analyses to shape perception and eye movements. A variety of methodological approaches are represented, including single-neuron recordings, fMRI and optical imaging, psychophysics, eye movement characterization and computational modelling.

This volume on Visual Psychophysics documents the current status of research aimed toward understanding the intricacies of the visual mechanism and its laws of operation in intact human perceivers. As can be seen from the list of contributors, the problems of vision engage the interest and experimental ingenuity of investi gators from a variety of disciplines. Thus we find authors affiliated with depart ments of biology, medical and physiological physics, ophthalmology, physics, physiology and anatomy, psychology, laboratories of neurophysiology, medical clinics, schools of optometry, visual and othcr types of research institutes. A continuing interplay between psychophysical studies and physiological work is everywhere evident. As more information about the physiological basis of vision accumulates, and new studies and analyses of receptor photochemistry and the neurophysiology of retina and brain appear, psychophysical studies of the intact organism become more sharply focused, sometimes more complex, and often more specialized. Technological advances have increased the variety and precision of the stimulus controls, and advances in measurement techniques have reopened old problems and stimulated the investigation of new ones. In some cases, new concepts are being drawn in to help further our under standing of the laws by which the visual mechanism operates; in other cases, ideas enunciated long ago have been reevaluated, developed more fully, and reified in terms of converging evidence from both psychophysical experiments and unit recordings from visual cells.
