Descriptions of basic visual mechanisms and related clinical abnormalities, by a neuroscientist and an ophthalmologist.

Over the past fifty years, enormous progress has been made in understanding visual mechanisms and treating eye disorders. And yet the scientist is not always aware of the latest clinical advances and the clinician is often not up to date on the basic scientific discoveries. Writing in nontechnical language, John and Joseph Dowling, a neuroscientist and an ophthalmologist, examine vision from both perspectives, providing concise descriptions of basic visual mechanisms and related clinical abnormalities. Thus, an account of the photoreceptors is followed by a consideration of retinitis pigmentosa and macular degeneration; an explanation of the retina''s function is followed by details of glaucoma and diabetic retinopathy.

The authors begin with the cornea and lens, which project an image on the light-sensitive elements inside the eye, the photoreceptors, and how that process can be compromised by such disorders as cataracts and corneal disease. They go on to describe, among other things, how the photoreceptors capture light; retinal and visual cortical anatomy and physiology; and higher level visual processing that leads to perception. Cortical disorders such as amblyopia are discussed as well as specific deficits such as the inability to recognize faces, colors, or moving objects. Finally, they survey the evolution of our knowledge of vision, and speculate about future advances.

John E. Dowling is Gordon and Llura Gund Research Professor of Neurosciences in the Department of Molecular and Cellular Biology at Harvard University.Joseph L. Dowling, Jr., is a practicing ophthalmologist and the founder of the Rhode Island Eye Institute.
