Neurology of Vision and Visual Disorders, Volume 178 in the Handbooks of Neurology series provides comprehensive summaries of recent research on the brain and nervous system. This volume reviews alterations in vision that stem from the retina to the cortex. Coverage includes content on vision and driving derived from the large amount of time devoted in clinics to determining who is safe to drive, along with research on the interplay between visual loss, attention and strategic compensations that may determine driving suitability. The title concludes with vision therapies and the evidence behind these approaches. Each chapter is co-written by a basic scientist collaborating with a clinician to provide a solid underpinning of the mechanisms behind the clinical syndromes. Reviews the neurological underpinnings of visual perception disorders Encompasses the cortex to the retina Covers functional organization, electrophysiology and subcortical visual pathways Discusses assessment, diagnosis and management of visual perception disorders Includes international experts from Australia, Canada, Denmark, Germany, Singapore, and the UK and US

The Neurology of Vision sets out the principles and information needed to understand and manage disorders of the visual pathways in the brain. The author divides vision into three components. The optical component addresses the eye's ability to properly focus light on the retina. The retinocortical component converts light into neural signals in the retina, transmitting them to the primary visual cortex. Finally, the integrative component converts this simple visual information into more complicated forms. The symptoms and signs, testing methods, and diseases of each part of the visual system are presented using this unique, structural component approach. A final chapter discusses the visual manifestations of psychiatric disturbances. The book is heavily illustrated with over 150 beautifully rendered line illustrations, 50 radiographic brain images, and 60 retinal photographs. Case studies with teaching questions are also included, to further the reader's knowledge and test understanding.

An investigation of the effects of blindness and other types of visual deficit on cognitive abilities. Can a blind person see? The very idea seems paradoxical. And yet, if we conceive of "seeing" as the ability to generate internal mental representations that may contain visual details, the idea of blind vision becomes a concept subject to investigation. In this book, Zaira Cattaneo and Tomaso Vecchi examine the effects of blindness and other types of visual deficit on the development and functioning of the human cognitive system. Drawing on behavioral and neurophysiological data, Cattaneo and Vecchi analyze research on mental imagery, spatial cognition, and compensatory mechanisms at the sensorial, cognitive, and cortical levels in individuals with complete or profound visual impairment. They find that our brain does not need our eyes to "see." Cattaneo and Vecchi address critical questions of broad importance: the relationship of visual perception to imagery and working memory and the extent to which mental imagery depends on normal vision; the functional and neural relationships between vision and the other senses; the specific aspects of the visual experience that are crucial to cognitive development or specific cognitive mechanisms; and the extraordinary plasticity of the brain—as illustrated by the way that, in the blind, the visual cortex may be reorganized to support other perceptual or cognitive funtions. In the absence of vision, the other senses work as functional substitutes and are often improved. With Blind Vision, Cattaneo and Vecchi take on the "tyranny of the visual," pointing to the importance of the other senses in cognition.

This book discusses more than one hundred patients in which visual pathway is involved, and focuses on the role of visual field examination in the diagnosis of these diseases. It also highlights the application of concepts from the new interdiscipline, integration medicine as well as molecular biology and genetics in the analysis of the diseases. In this book, the commonly (typically) noticed changes in the visual field of patients with visual pathway disorders are mainly described in the chapter one titled as “Visual Field-related Anatomy of Visual Pathway” and chapter two titled as “Interpretation of Visual Field Test”, while the majority of the cases presented with "atypical" changes in visual field. At this point, the changes in the visual field could function as either a key to understand the disease, or a question mark which confuses the diagnosis. However, the process of pushing aside a fog around the diagnosis step by step helps the readers to gradually disclose the essence of the disease.

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.

An unprecedented book that discusses a decades long journey of understanding vision and visual impairment through working with patients with brain damage Edward de Haan, a noted clinical vision researcher for the last 35 years, explains how the healthy brain deals with visual information and reveals how he learned to appreciate what it means to be visually impaired. Through discussions of fascinating case studies, he shows that visual deficits are individually unique. Some patients perceive the world without color, some see objects in a distorted manner, whilst others will claim that they can still see although they are demonstrably blind. The author details his experiences with these patients to demonstrate the manner in which patient work is a unique and vital part of discovering how the brain processes visual information. In doing so, Impaired Vision offers a review of the clinical symptoms related to visual impairment and highlights that the patient study method has not lost any of its relevance in our increasingly high-tech world. This important book: Explores the various clinical phenomena in visual impairment after brain damage Demonstrates the effectiveness of the patient study method for understanding visual deficits after brain damage Contains comprehensive coverage of the variety of symptoms that are manifest in patients with visual impairment Includes compelling case studies of visually impaired patients Written for a general audience but of interest for students, researchers and clinicians, Impaired Vision contains fascinating case studies that offer an understanding of the symptoms that are associated with visuals deficits of brain damage.

Despite a long research tradition in visual neuroscience, the rehabilitation of cerebral visual deficits has, until recently, been neglected. This book is the first to report systematic observations on spontaneous recovery of cerebral visual deficits after acquired brain injury, and the outcome of treating these deficits. The whole range of human visual functions and capacities is covered: visual field, visual acuity and contrast sensitivity, visual adaptation, colour vision, visual space perception, and visual cognition. Additionally, there is a special section devoted to patients with central scotoma. All treatment procedures described are empirically founded.

Cerebral visual disorders have far-reaching consequences for child development. These have profound adverse effects on children’s education and success in school and also in later life, but, unfortunately, cerebral visual disorders often remain undiagnosed and untreated in the pediatric population. This book provides a state-of-the-art account of what is known about the development and disorders of visual perception in children. It covers the development and disorders of visual perception in children, their assessment, early intervention and management in an interdisciplinary context, both from a scientific as well as clinical perspective. Case studies illustrate the recommended assessment and rehabilitation procedures; synopses, boxes and check-lists complement the presentation of our recommendations for clinical practice.

A comprehensive review of visual impairment in children and possible solutions The rising number of cases in visual disorders during development, over the last decade, has strongly influenced approaches to diagnosis and rehabilitation. Moreover, the study of visual function has evolved not only within an ophthalmological, but also a neurodevelopmental framework: advances in our understanding of the maturation and plasticity of visual system functioning have further guided the progress of such approaches. As a result, the key importance of the developmental age is now widely acknowledged, from as early as the first months of life. This book provides an overview of the diagnosis and treatment of visual disorders in relation to advances in neurodevelopmental studies. The concept of early and multimodal management is discussed, with a focus on neuro-psycho-ophthalmological issues. The need for training courses aimed at updating semiological aspects and methodological and rehabilitative strategies is established, as being of significant value to clinical practice. 4 parts: General overviewCerebral visual impairments: from diagnosis to rehabilitationRehabilitation of visual impairmentsVisual disorders and neurological diseases
