Download or read book Optic Disorders and Visual Field written by Ningli Wang and published by Springer. This book was released on 2019-03-01 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Practical Guide to Interpret Visual Fields written by GR Reddy and published by Jaypee Brothers Medical Publishers. This book was released on 2020-02-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual field refers to the total area in which objects can be seen in the side (peripheral) vision when the eyes are focused on a central point. Glaucoma is a condition of the eye in which the optic nerve is damaged due to increased fluid pressure in the eye. If untreated or uncontrolled, glaucoma first causes peripheral vision loss and eventually can lead to blindness. A visual field test is a method of measuring an individual's entire scope of vision, that is their central and peripheral (side) vision. The test is most frequently used to help detect glaucoma but may also be used for detection of central or peripheral diseases of the retina, eyelid conditions such as drooping (ptosis), optic nerve damage and disease, and conditions affecting the visual pathways from the optic nerve to the area of the brain (occipital cortex) where this information is processed into vision. The fourth edition of this comprehensive text provides ophthalmologists and trainees with a guide to the interpretation of visual field tests and subsequent diagnosis and management of ocular disorders. The book has been fully revised and features additional topics including two new classification systems for glaucoma. Nearly 800 clinical photographs and diagrams further enhance learning.

Download or read book The Neurology of Vision written by Jonathan D. Trobe and published by Oxford University Press. This book was released on 2001-03-29 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.
