This basic text covers the evaluation, diagnosis, and treatment of the most prevalent vision disorders in a clinical optometrist's or ophthalmologist's practice. Coverage includes the most common non-strabismic binocular vision disorders, including accommodative and eye movement disorders as well as amblyopia. Coverage of each diagnostic category includes background information, symptoms, case analysis, and management options. Case studies appear at the end of each chapter. This edition includes three new chapters on primary care of binocular vision, accommodative and eye movement disorders; myopia control; and binocular vision problems associated with refractive surgery. The thoroughly revised chapters on vision therapy procedures and instrumentation describe the latest equipment and computer software. The chapters on advanced diagnostic and management issues have been updated with the latest research.

This popular manual introduces the organization and analysis of clinical optometric data used in writing prescriptions for glasses. This edition has been greatly expanded to include new information on accommodative disorders and fixation disparity (among others). Case reports integrated throughout the text illustrate the management process.

No systematic analysis of optometric clinical data can be undertaken unless the findings are referred to a logical model that allows comparisons to be made of interaction characteristics that exist between the accommodative and convergence mechanisms inherent to the human vision system. Concomitantly, many of the concepts applied during any such analytical process are based on hypothetical constructs. This text re-examines the elements originally proposed by Dr. A.M. Skeffington, and offers a revised insight into how performance changes may occur as individual visual behavior adapts to the impact of environmental demands. In-depth research and extensive references attempt to substantiate the Skeffington paradigm of professional vision analysis. Long-standing challenges to the optometric profession are identified. As presented, the contents are appropriate for use as a classroom text, for reference, and for identifying areas for clinical research.

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.

This fourth edition of Clinical Management of Binocular Vision uses the past five years of research studies and literature to provide an accurate look at today’s diagnosis and treatment of binocular vision. Written with an emphasis on proper evaluation, diagnosis, and treatment, each condition is covered in-depth and includes background information, symptoms, case analysis, and management options. This edition also includes the latest information on new vision therapy equipment. Easy to read and understand, this book is ideal for faculty when designing courses, students studying these topics for the first time, or established practitioners looking for a practical, easy-to-use reference on accommodative, ocular motility, and nonstrabismic vision anomalies.

In Eye Movement Disorders in Clinical Practice, a leading expert with over thirty years of teaching experience in neurology and neuro-ophthalmology offers comprehensive instruction on the diagnosis and treatment of all varieties of eye movement disorders. This important new text reflects the importance of correlating clinical signs of disorders in the oculomotor system with their neuroanatomic and neurophysiologic architecture. With its focus on signs and symptoms, the book advances lesion localization of eye movement disorders as the central clinical concern. The reader is also presented with a fresh review of bedside examination techniques in the ER, ICU, and walk-in clinic; productive ways of taking a clinical history; sign interpretation; source lesion localization; and, where appropriate, therapy. Unlike most of the titles on eye movement disorders, this book's chapters are arranged according to objective signs - like ptosis, neuromuscular syndromes, dizziness, vertigo, and syndromes of the medulla - rather than disease entities. This emphasis on the topographic analysis of symptoms and signs is contrary to the prevailing clinical approach in which responsibility for therapy typically drives the clinician to arrive at an etiological diagnosis as rapidly as possible. At risk in this process is nothing less than the art of clinical medicine. One of the aims of this book is to reverse this process, and move clinicians back to the observation and interpretation of signs. The text features over 100 clinical cases, each one challenging the reader to determine the neuroanatomical location of the patient's lesion. This exercise provides the anatomical guidance needed to make critical diagnostic and management decisions in patients who often present with abnormal eye movements. Dynamic and intellectually stimulating, Eye Movement Disorders in Clinical Practice is essential for any reader wanting to better understand eye movement disorders.

This book is a survey of knowledge about binocular vision, with an emphasis on its role in the perception of a three-dimensional world. The primary interest is biological vision. In each chapter, physiological, behavioral, and computational approaches are reviewed in some detail, discussed, and interrelated. The authors describe experiments required to answer specific questions and relates them to new terminologies and current theoretical schemes.

The Neurology of Eye Movements provides clinicians with a synthesis of current scientific information that can be applied to the diagnosis and treatment of disorders of ocular motility. Basic scientists will also benefit from descriptions of how data from anatomical, electrophysiological, pharmacological, and imaging studies can be directly applied to the study of disease. By critically reviewing such basic studies, the authors build a conceptual framework that can be applied to the interpretation of abnormal ocular motor behavior at the bedside. These syntheses are summarized in displays, new figures, schematics and tables. Early chapters discuss the visual need and neural basis for each functional class of eye movements. Two large chapters deal with the evaluation of double vision and systematically evaluate how many disorders of the central nervous system affect eye movements. This edition has been extensively rewritten, and contains many new figures and an up-to-date section on the treatment of abnormal eye movements such as nystagmus. A major innovation has been the development of an option to read the book from a compact disc, make use of hypertext links (which bridge basic science to clinical issues), and view the major disorders of eye movements in over 60 video clips. This volume will provide pertinent, up-to-date information to neurologists, neuroscientists, ophthalmologists, visual scientists, otalaryngologists, optometrists, biomedical engineers, and psychologists.
