Strabismus is a disorder in which the eyes are misaligned. This volume is the most advanced reference for techniques in diagnosis and treatment of strabismus. Chapters cover diagnosis of, surgical and nonsurgical treatments for, and management of esotropia (eyes aligned inward) exotropia (eyes aligned outward), dissociated strabismus complex, paralytic strabismus, restrictive strabismus, and nystagmus. It also contains a chapter on reoperation strategies.

This book covers a wide range of topics concerning human tear based science, starting from basics such as the normal composition of tears and moving up to novel disease detection platforms. The entire approach is pioneering, as tears are beginning to be recognized as the most invaluable non-invasive tool in diagnostics. Interestingly, the concept is not restricted to ocular diseases: In recent years, tear diagnostics is increasingly being tapped even for cancer detection. Hopefully, non-invasive tear diagnostics will eventually replace today's invasive disease detection and monitoring techniques. Previous literature on tear diagnostics has been restricted to scientific journal articles, most of which dealt with a single tear constituent, such as a protein. This book offers a far more comprehensive and handy 'reference guide,' presenting both basic and advanced information and data. Accordingly, it will be useful for researchers in academia and the pharmaceutical industry, as well as healthcare professionals and diagnostic kit developers.

The Neuropsychology of Vision describes a range of new approaches to neuropsychological investigation and provides a broad overview of visual neuropsychology. The book starts by presenting the results from new research employing single-unit recordings, on the neuronal basis of perception demonstrating that the visual system relies strongly on feedback from higher to lower levels of information processing, and that neuronal plasticity exists in the primary sensory cortices of adults, areas previously considered to be hard-wired. The book also describes other new and adapted techniques to measure brain activity, including multi-unit sum potential recording, functional magnetic resonance imaging and employing transcranial magnetic stimulation to induce temporary, circumscribed functional lesions in the cortices of normal subjects to mimic disorders.

The coverage then moves on to review the experience of patients suffering from disturbances of visual perception. The disorders covered include agnosia, neglect, blindsight and achromatopsia. The final chapter is devoted to recovery and rehabilitation from cerebral visual disorder.

Over the weekend of 21-23 February 1997, a small group gathered in Tallahassee, Florida, at the invitation of Ted Williams, to discuss "photo stasis and related topics." The majority of participants were former students and colleagues of Ted's, but an occasional outsider such as myself was generously included. The papers presented there are collected in this volume. The theory of photo stasis was first outlined in a landmark paper by John Penn and Ted, published in 1986 in Experimental Eye Research. They provided compelling data showing that, in the albino rat eye, levels of rhodopsin, outer-segment length, rhodopsin regeneration rate, and even, perhaps, rhodopsin packing density all depend on the levels of cyclic illumination (12 hours light, 12 hours dark) in which the animal was reared. So, for example, there is fourfold less rhodopsin in a retinal extract derived from an animal reared at 400 lux than in an extract from the retina of an animal reared at 3 lux. Animals reared at intermediate levels of light show intermediate amounts of rhodopsin that are correlated with illumination level. What these data immediately suggested is that the photoreceptor cell can adjust its photon-catching ability in response to the levels of light in which an animal is reared, and they also provided a compelling rationale for outer-segment turnover, a phenomenon discovered 20 years earlier by Richard Young but whose function has remained obscure.
