Binocular vision, i.e. where both eyes are used together, is a fundamental component of human sight. It also aids hand-eye co-ordination, and the perception of the self within the environment. Clinical anomalies pose a wide range of problems to the sufferer, but normal binocular operation must first be understood before the eye specialist can assess and treat dysfunctions. This is a major new textbook for students of optometry, orthoptics and ophthalmology, and also of psychology. Chapters span such key topics as binocular summation, fusion, the normal horopter, anatomy of the extra-ocular muscles, oculomotor control, binocular integration and depth perception. Fully illustrated throughout, the book includes self-assessment exercises at the end of each chapter, and sample experiments in binocular vision functioning.

In an easy-to-follow format, this text offers an organized approach to the analysis of optometric data, diagnosis and treatment of accommodative and binocular vision disorders. The unique presentation of the material by diagnostic category allows the quick retrieval of information, according to the diagnostic condition. Each condition or diagnosis includes background information, symptoms, signs, case analysis and management options, with emphasis on principles of treatment and treatment alternatives. Case studies at the end of each chapter further emphasize the application to clinical care.

Comprehensive textbook on the design and visual ergonomics of optical instruments.

When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.

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.

From a renowned author team comes a clinically oriented approach to the introductor study of binocular vision. Essential reading for second-year optometry students, this vital core text covers testing procedures, diagnostic issues, and treatment modalities in preparation for more advanced clinical work. Key points to remember for national board exams are highlighted and discussions of clinical applications and procedures abound in every chapter.

A revelatory account of the brain's capacity for change When neuroscientist Susan Barry was fifty years old, she experienced the sense of immersion in a three dimensional world for the first time. Skyscrapers on street corners appeared to loom out toward her like the bows of giant ships. Tree branches projected upward and outward, enclosing and commanding palpable volumes of space. Leaves created intricate mosaics in 3D. Barry had been cross-eyed and stereoblind since early infancy. After half a century of perceiving her surroundings as flat and compressed, on that day she saw the city of Manhattan in stereo depth for first time in her life. As a neuroscientist, she understood just how extraordinary this transformation was, not only for herself but for the scientific understanding of the human brain. Scientists have long believed that the brain is malleable only during a "critical period" in early childhood. According to this theory, Barry's brain had organized itself when she was a baby to avoid double vision - and there was no way to rewire it as an adult. But Barry found an optometrist who prescribed a little-known program of vision therapy; after intensive training, Barry was ultimately able to accomplish what other scientists and even she herself had once considered impossible. Dubbed "Stereo Sue" by renowned neurologist Oliver Sacks, Susan Barry tells her own remarkable journey and celebrates the joyous pleasure of our senses.
