Download or read book The Neurology of Eye Movements Text and CD ROM written by Departments of Neurology R. John Leigh Professor, Neuroscience Otolaryngology and Biomedical Engineering Case Western Reserve University University Hospitals and Veterans Affairs Medical Center Cleveland Ohio and published by Oxford University Press, USA. This book was released on 1999-08-26 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Visual Impairments written by National Research Council and published by National Academies Press. This book was released on 2002-08-17 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 1999-01-31 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human behaviour and communication relies heavily on visual guidance and visually coded information and therefore is tightly coupled to eye movements. Consequently many parts of our brains are involved in eye movement control and phenomena contingent on eye movement. This volume covers the latest research from a large group of laboratories covering all aspects of oculomotor research, from physiology, engineering and medical sciences to experimental psychology and cognitive sciences.

Download or read book Visual Psychophysics written by Dorothea Jameson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Mind s Eye written by Ralph Radach and published by Elsevier. This book was released on 2003-06-05 with total page 763 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a comprehensive state-of-the-art overview of current research on cognitive and applied aspects of eye movements. The contents include peer-reviewed chapters based on a selection of papers presented at the 11th European Conference on Eye Movements (Turku, Finland 2001), supplemented by invited contributions. The ECEM conference series brings together researchers from various disciplines with an interest to use eye-tracking to study perceptual and higher order cognitive functions. The contents of the book faithfully reflect the scope and diversity of interest in eye-tracking as a fruitful tool both in basic and applied research. It consists of five sections: visual information processing and saccadic eye movements; empirical studies of reading and language production; computational models of eye movements in reading; eye-tracking as a tool to study human-computer interaction; and eye movement applications in media and communication research. Each section is concluded by a commentary chapter by one of the leading authorities in the field. These commentaries discuss and integrate the contributions in the section and provide an expert view on the most significant present and future developments in the respective areas. The book is a reference volume including a large body of new empirical work but also principal theoretical viewpoints of leading research groups in the field.

Download or read book Emergent Techniques for Assessment of Visual Performance written by National Research Council and published by National Academies Press. This book was released on 1985-01-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent vision research has led to the emergence of new techniques that offer exciting potential for a more complete assessment of vision in clinical, industrial, and military settings. Emergent Techniques for Assessment of Visual Performance examines four areas of vision testing that offer potential for improved assessment of visual capability including: contrast sensitivity function, dark-focus of accommodation, dynamic visual acuity and dynamic depth tracking, and ambient and focal vision. In contrast to studies of accepted practices, this report focuses on emerging techniques that could help determine whether people have the vision necessary to do their jobs. In addition to examining some of these emerging techniques, the report identifies their usefulness in predicting performance on other visual and visual-motor tasks, and makes recommendations for future research. Emergent Techniques for Assessment of Visual Performance provides summary recommendations for research that will have significant value and policy implications for the next 5 to 10 years. The content and conclusions of this report can serve as a useful resource for those responsible for screening industrial and military visual function.

Download or read book Eye Movement Disorders in Clinical Practice written by Shirley H. Wray and published by Oxford University Press. This book was released on 2014 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Perceiving in Depth Volume 1 written by Ian P. Howard and published by OUP USA. This book was released on 2012-02-24 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world.Volume 1 starts with a review of the history of visual science from the ancient Greeks to the early 20th century with special attention devoted to the discovery of the principles of perspective and stereoscopic vision. The first chapter also contains an account of early visual display systems, such as panoramas and peepshows, and the development of stereoscopes and stereophotography. A chapter on the psychophysical and analytic procedures used in investigations of depth perception is followed by a chapter on sensory coding and the geometry of visual space. An account of the structure and physiology of the primate visual system proceeds from the eye through the LGN to the visual cortex and higher visual centers. This is followed by a review of the evolution of visual systems and of the development of the mammalian visual system in the embryonic and post-natal periods, with an emphasis on experience-dependent neural plasticity. An account of the development of perceptual functions, especially depth perception, is followed by a review of the effects of early visual deprivation during the critical period of neural plasticity on amblyopia and other defects in depth perception. Volume 1 ends with accounts of the accommodation mechanism of the human eye and vergence eye movements.

Available in PDF, EPUB and Kindle. Book excerpt: Vertigo, dizziness, and imbalance rank amongst the most common presenting symptoms in neurology, ENT, geriatric medicine, and general practice. These symptoms can originate from many different organs and systems, such as the inner ear, general medical conditions, neurological and psychological disorders. The Oxford Textbook of Vertigo and Imbalance provides an up-to-date summary of the scientific basis, clinical diagnosis, and management of disorders leading to dizziness and poor balance. This textbook is conceptually divided into three sections, detailing the scientific basis, general clinical issues, and specific diseases diagnosed in clinical practice that are responsible for complaints of dizziness and imbalance. Individual chapters address benign paroxysmal positional vertigo, vestibular migraine, vestibular neuritis, stroke, and Ménière's disease. Additional chapters follow a syndrome-based approach and cover multiple conditions, including cerebellar disorders, bilateral vestibular failure and gait, and psychological disorders. The print edition is complemented by an online version, which allows access to the full content of the textbook, contains links from the references to primary research journal articles, allows full text searches, and provides access to figures and tables that can be downloaded to PowerPoint. It serves a useful clinical reference for neurologists, otorhinolaryngologists, audio-vestibular physicians, and senior trainees in those specialties.
