During the last few centuries, natural philosophers, and more recently vision scientists, have recognized that a fundamental problem in biological vision is that the sources underlying visual stimuli are unknowable in any direct sense, because of the inherent ambiguity of the stimuli that impinge on sensory receptors. The light that reaches the eye from any scene conflates the contributions of reflectance, illumination, transmittance, and subsidiary factors that affect these primary physical par...
For people who start losing their vision to macular degeneration, the prospect of impending blindness is frightening and terribly depressing. They often get contradictory advice about surgery, medical treatments, natural supplements and lifestyle changes that might arrest or reverse the condition - and these conflicting recommendations only compound their anxiety. This book casts the spotlight on macular degeneration and dispels the myths surrounding this disease. MACULAR DEGENERATION offers a...
Neurology of Vision and Visual Disorders (Handbook of Clinical Neurology)

This volume reviews alterations in vision that stem from the retina to the cortex. Coverage includes content on vision and driving derived from the large amount of time devoted in clinics to determining who is safe to drive, along with research on the interplay between visual loss, attention and strategic compensations that...
Having cataract surgery? Nearly 3 million Americans who have cataracts removed each year. In fact, it's the most commonly performed surgery in the nation. And, the numbers are expected to increase--by the year 2020, nearly 30 million Americans will have cataracts.

In former So\\jet Union countries there are currently underway or being planned, several major ocular follow-up studies of populations exposed to radiation from reactor accidents, contamination from nuclear weapons manufacturing or fall-out from nuclear testing. The importance of such studies lies in their potential to provide the data necessary to: 1) help define the true extent of the impact of environmental contamination in affected regions 2) allow for a better appreciation of the degree of...

by Hans Drischel
Cataract is the major cause of blindness in man throughout the world. It is usually dealt with by surgery but surgery is expensive and may lead to other ocular damage. Apart from surgery one might hope to prevent cataracts or to cure them, but these approaches require a much greater understanding of the structure and metabolism of the lens and of its weaknesses and strengths. The emphasis of this book is on recent findings. The first chapter deals with the normal lens and its structure, cellular...

The International Life Sciences Institute (ILSI) was established in 1978 to stimulate and support scientific research and educational programs related to nutrition, toxicology, and food safety, and to encourage cooper- ation in these programs among scientists in universities, industry, and government agencies to assist in the resolu- tion of health and safety issues. To supplement and enhance these efforts, ILSI has made a major commitment to supporting programs to har- monize toxicologic testin...
