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.

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

This book was released on 2017-01-15 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.

This book was released on 2012-12-06 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 5th International Visual Field Symposium of the International Peri metric Society was held on October 20-23, 1982, in Sacramento, California, before the joint meeting of the International Congress of Ophthalmology and the American Academy of Ophthalmology. A majority of the members of the International Perimetric Society took part in the meeting together with many guests. The topics of the symposium were: glaucoma: correlation between the visual field and the optic disc; the visual field in low-tension glaucoma; neuro-ophthalmology and ergo-perimetry. Apart from this there were many papers on automated perimetry and general topics. The papers concerning the correlation of optic disc and visual field dealt with several aspects: peripapillary atrophy, defects in the retinal nerve fiber layer, fluorescein angiography and the characteristics of the glaucomatous excavation itself. New and interesting findings were presented showing that the careful, detailed observation of the disc and peripapillary area is re warding. The visual fields in low-tension glaucoma were studied extensively by four groups. Various approaches to the problem have led to some differences in results, which were extensively discussed. In the general glaucoma session the visual fatigue phenomenon was dis cussed extensively; apparently conflicting results were demonstrated re garding the stability of contrast threshold measurements during one and the same test session in glaucoma. The relationship between the visual field and the performance at the working place was considered in the session on ergo-perimetry.

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

This book was released on 2012-12-06 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 4th International Visual Field Symposium of the International Perimetric Society, was held on the 13-16 April 1980 in Bristol, England,at the occasion of the 6th Congress of the European Society of Ophthalmology. The main themes of the symposium were comparison of classical perimetry with visual evoked response, comparison of classical perimetry with special psychophysi cal methods, and optic nerve pathology. Understandably many papers dealt with computer assisted perimetry. This rapidly developing subgroup of peri metry may radically change the future of our method of examination. New instruments were introduced, new and exciting software was proposed and the results of comparative investigations reported. There have been many confusing statements in the literature on the relative value of perimetry and the registration of visual evoked responses. Several reports attempted to bring some clarity in this issue. There is reason for further comparative research. A number of papers dealt with special psychophysical methods, i.e. methods not using the simply monocular differential threshold. The old critical fusion frequency received new attention. Fundusperimetry was used for testing spatial summation. Acuity perimetry, binocular perimetry etc. showed that there exist many possibilities for examining visual function. At present it is not clear to us what exactly the place of these methods is in our diagnostic armament. However it is quite clear that some of them are promising and may lead to a further differentiation of perimetric methods.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction We mark the eighth consecutive year for the World Glaucoma Association Glaucoma Consensus with Consensus VIII. Our topic is the Progression of Glaucoma. Global experts were invited and assembled by our international co-Chairs beginning in January 2011, to participate in the Project Forum E-Room, a unique online opportunity to facilitate discussion of each of the consensus meetings. Participants then were engaged in the discussion of five topical areas to reach consensus on key issues that surround and permeate all aspects of the progression of glaucoma. The results of these thoughtful discussions then were summarized by each of the sections with preliminary consensus statements. The Draft of the Consensus Report, including the preliminary consensus statements, was distributed to the Societies and Partners for review and comments prior to the Consensus Meeting that took place in Paris on Tuesday, June 28, 2011. On this day, relevant stakeholders engaged in a stimulating, educational, and thought-provoking session that highlighted the review and revision of the consensus statements. The Consensus Report then was finalized by Consensus co- Chairs and Editors. Consensus statements were reviewed and finalized by the expert Consensus Panel. Robert N. Weinreb, Editor

Available in PDF, EPUB and Kindle. Book excerpt: Filmed images dominate our time, from the movies and TV that entertain us to the news and documentary that inform us and shape our cultural vocabulary. Crossing disciplinary boundaries, Fields of Vision is a path-breaking collection that inquires into the power (and limits) of film and photography to make sense of ourselves and others. As critics, social scientists, filmmakers, and literary scholars, the contributors converge on the issues of representation and the construction of visual meaning across cultures. From the dismembered bodies of horror film to the exotic bodies of ethnographic film and the gorgeous bodies of romantic cinema, Fields of Vision moves through eras, genres, and societies. Always asking how images work to produce meaning, the essays address the way the "real" on film creates fantasy, news, as well as "science," and considers this problematic process as cultural boundaries are crossed. One essay discusses the effects of Hollywood's high-capital, world-wide commercial hegemony on local and non-Western cinemas, while another explores the response of indigenous people in central Australia to the forces of mass media and video. Other essays uncover the work of the unconscious in cinema, the shaping of "female spectatorship" by the "women's film" genre of the 1920s, and the effects of the personal and subjective in documentary films and the photographs of war reportage. In illuminating dark, elided, or wilfully neglected areas of representation, these essays uncover new fields of vision.

The Proceedings of this symposium follow the general lines of the pro gramme with some minor alterations. This symposium was a so-called topic-symposium where selected topics were introduced by experts in the field. These topics were: Neuro-ophtha[mo[ogy. 1. Funduscopic correlates of visual field defects. 2. Visual field defects due to tumors of the sellar region. Glaucoma. 1. The earliest visual field defects in glaucoma. 2. The reversibility of glaucomatous visual field defects. Methodology. 1. Automation. 2. The relation between the position of a lesion in the fundus and in the visual field. Apart from the introductory papers, free papers were given on the topics non-topic free papers. and also some Much attention has been given to the discussion. Most of the discussion remarks in this Proceedings are the original taped remarks of the discussion speakers. We have choosen this form of presentation to take to the reader the athmosphere of the discussion and to preserve originality. The chairman of the sessions have presented a summary or even better an interpretation of the trends in their topics. This introduction gives a short overview of the main themes of the symposium.

Available in PDF, EPUB and Kindle. Book excerpt: Visual research methods (VRM) comprise a collection of methods that incorporate visual elements such as maps, drawings, photographs, videos, as well as three-dimensional objects into the research process. In addition, VRM including photo-elicitation, photovoice, draw-and-write techniques, and cognitive mapping are being leveraged to great effect to explore information experiences to investigate some of the central questions in the field; expand theoretical discussions in LIS; and improve library services and spaces. Visual Research Methods: An Introduction for Library and Information Studies is the first book to focus on visual methods in LIS, providing a comprehensive primer for students, educators, researchers and practitioners in the field. Contributed chapters in the book showcase examples of VRM in action and offer the insights, inspirations, and experiences of researchers and practitioners working with visual methods. Coverage includes: - an introduction to visual research methods including a discussion of terminology - an overview of the literature on VRM in libraries - methodological framing including a discussion of theory, epistemology, - practical and ethical considerations for researchers embarking on VRM projects - chapters showcasing VRM in action including drawing techniques, photographic techniques, and mixed methods - six contributed chapters each showcasing the results of visual research methods, discussions of the techniques, and reflections on VRM for research in information studies. This book will provide a strong methodological context for the adoption of visual research methods in LIS and feature examples of VRM ‘in action.’ It will prove to be a must-have reference for researchers, practitioners, instructors, and students who want to engage with visual research methods and to expand their methodological toolkit.

Book excerpt: In his latest book, James Elkins offers a road map through the field of visual studies, describing its major concerns and its principal theoretical sources. Then, with the skill and insight that have marked his successful books on art and visuality, Elkins takes the reader down a side road where visual studies can become a more interesting place. Why look only at the same handful of theorists? Why exclude from one's field of vision non-Western art or the wealth of scientific images?
