DOWNLOAD EBOOKA comprehensive survey on the use of bedside skills and perimetric devices to the test visual fields, and how to interpret the results. To develop the clinician's interpretative skills, the authors include a chapter on visual anatomy and an atlas of 100 real-life cases arranged in anatomic order from retina to striate cortex. By placing a brief clinical vignette with a visual field on one side of the page and a description of the field and its causal lesion on the opposite side, the reader will be able to learn interpretation in a simulated clinical setting. An additional quiz section of twenty randomly arranged visual fields provides readers with an opportunity to test their newly acquired skills.

DOWNLOAD EBOOKThis 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 EBOOKVisual Fields: Examination and Interpretation, 3rd edition contains revisions and updates of earlier material as well as a discussion of newer techniques for assessing visual field disorders. The book begins with a short history of the field of perimetry and goes on to present basic clinical aspects of examination and diagnosis of visual field defects in the optic nerve, optic disc, chorioretina, optic chiasm, optic tract, lateral geniculate field bodies, and the calcarine complex. Additional aspects of visual field examination are explored including those of monocular, binocular, and junctional field defects, congruity vs. incongruity, macular sparing vs. macular splitting, density, wedge-shaped homonymous field loss, and monocular temporal crescent. Various new techniques of automated perimetry are also considered including SITA, FASTPAC, and SWAP. This volume provides a very useful overview of the techniques of visual field examination in a number of eye disorders and will be of interest to all ophthalmologists, neuro-opthalmologists, retina specialists, and optometrists.

DOWNLOAD EBOOKAn introduction by ophthalmologists to the use of the Humphrey Field Analyzer (both older and newer models) in automated perimetry. After discussing the principles of the computer measurement of peripheral vision fields, hardware methodologies and software interpretations are detailed. Finally, specific classes of visual field defects such as glaucoma, neuro-ophthalmology, and miscellaneous conditions are explored. Throughout are numerous pictures of Humphrey printouts which provide examples of perimetry test results for both healthy and diseased eyes. Annotation copyrighted by Book News, Inc., Portland, OR

DOWNLOAD EBOOKWhen 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.
