Visual Fields Via The Visual Pathway Second Edition written by Fiona Rowe and has been published by CRC Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 2015-12-22 with Medical categories.


This book is a basic reference guide on the anatomy of the visual pathway, the layout/topography of the nerve fibers throughout the visual pathway, typical lesions affecting each part of the visual pathway, the visual field defects to be expected at each level, and the associated signs and symptoms (ocular and general) at each level of the visual pathway. It includes examples of visual field results enhanced by illustrative photographs and brain scans as appropriate to each part of the visual pathway and pathology. Also included are sections on differential diagnose and artefacts of testing. New features to this edition include updated methods of visual field assessment, additional descriptions of how individual visual field results should be interpreted, an updated review of the pros and cons of the various available test programs, and in each chapter a discussion of recent research advances and recommendations on baseline assessment, diagnosis, and re-assessment options to promote good clinical practice decisions.

This textbook is a dynamic exploration of the relationship between the visual pathway and visual field impairments. Aimed at the practitioner or student of visual fields, the clinical focus of the book is oriented towards differential diagnosis and will assist the reader in identifying the site of a lesion. The emphasis is on detection and interpretation of visual field defects, rather than the background and psychophysics of visual field assessment. Discussion of the normal visual field is included for comparative purposes. The structure of the book traces the visual pathway anatomically from front to back, and is supplemented by information on methodology and programme choice.

Visual Fields via the Visual Pathway presents the varying visual field deficits occurring with lesions of the visual pathway. The book covers anatomy, pathology and signs and symptoms, plus visual field defects associated with specific parts of the visual pathway. Also covered is the basic theory of visual field assessment. This new edition includes updated methods of visual field assessment, additional descriptions of how individual visual field results should be interpreted, an updated review of the pros and cons of the various available test programs, and recent research advances and recommendations on baseline assessment, diagnosis, and re-assessment options to promote good clinical practice decisions. The book expands on the previous edition to consider further types of perimetry and also updates existing perimetry information. The Octopus 900 perimetry, introduced since the first edition, features alongside Goldmann and Humphrey perimeters. Artefacts of testing are discussed as well as their identification versus actual visual field deficit. A section on differential diagnosis is also included. Chapters include numerous illustrations of visual field results, colour plates of associated fundus images, and neuroimaging scans. References and further reading lists are also provided with key articles and up-to-date literature.

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.

Homonymous Visual Field Defects written by Karolína Skorkovská and has been published by Springer this book supported file pdf, txt, epub, kindle and other format this book has been release on 2017-04-30 with Medical categories.


This book provides a concise, up-to-date overview on homonymous visual field defects, and especially homonymous hemianopia. All aspects of the subject are covered, from anatomy and pathophysiology to diagnosis and management. Emphasis is placed on practical issues and major advances in ophthalmology, neurology, imaging techniques, and psychology. Rehabilitation strategies are described, and methods supporting compensation strategies are recommended. A separate chapter considers driving with homonymous hemianopia, which represents one of the critical issues in traffic ophthalmology. This book will be of particular value to ophthalmologists, neurologists, neurosurgeons, and neuroscientists. It will be an invaluable asset in diagnostic and treatment decision making in patients with homonymous visual field defects, which are the most frequent type of visual field deficit after acquired unilateral postchiasmal brain damage. ​

This book covers interpretation of visual fields by Humphrey and Octopus perimeters and discussion of Humphrey visual fields in a variety of ocular disorders.It examines dilemmas faced by an ophthalmologist while evaluating visual fields which do not match with the clinical picture. Glaucoma, the commonest condition for visual field investigation is discussed in detail. Logical reasoningfor incorporating perimetry in glaucoma management with a clear understanding of the challenges in its interpretation is delved into. The book progresses to advanced glaucoma and glaucoma progression. It discusses a systematic evaluation of various parts of the visual field so that the reader can make a calculated management plan for their patient. Each chapter attempts to clearly enunciate factors that help in the diagnosis and features which may be confused with other conditions. Fields which help diagnosing early, advanced glaucoma and glaucoma progression with images and methods of ensuring reasonable diagnostic accuracy are included. The book incorporates separate chapters on ocular conditions which also mimic visual field defects of glaucoma with detailed modes of correct diagnosis, diagnostic dilemmas arising from retinal, macular, vascular, visual pathway lesions mimicking visual field defects of glaucoma or while coexisting with glaucoma, supported by algorithms to achieve a quick diagnosis in a busy OPD without missing the clinical findings and by using minimal investigative modalities. This book helps clinicians to prevent over diagnosis or under diagnosis of glaucoma and helps diagnose cases with morbidities causing visual field defects.
