Visual Impairments

Visual Impairments PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309083486
Category : Social Science
Languages : en
Pages : 369

Book Description
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.

Cortical Visual Impairment

Cortical Visual Impairment PDF Author: Christine Roman-Lantzy
Publisher: American Foundation for the Blind
ISBN: 0891288295
Category : Education
Languages : en
Pages : 225

Book Description
The current leading cause of visual impairment among children is not a disease or condition of the eyes, but cortical visual impairment (CVI)-also known as cerebral visual impairment-in which visual dysfunction is caused by damage or injury to the brain. The definition, nature, and treatment of CVI are the focus of great concern and widespread debate, and this complex condition poses challenges to professionals and families seeking to support the growth and development of visually impaired children. On the basis of more than 30 years' experience in working with hundreds of children of all ages with CVI, Christine Roman-Lantzy has developed a set of unique assessment tools and systematic, targeted principles whose use has helped children learn to use their vision more effectively. This one-of-a-kind resource provides readers with both a conceptual framework with which to understand working with CVI and concrete strategies to apply directly in their work.

Low Vision: Assessment and Educational Needs

Low Vision: Assessment and Educational Needs PDF Author: Dr. G. Victoria Naomi
Publisher: Partridge Publishing
ISBN: 1482889676
Category : Health & Fitness
Languages : en
Pages : 121

Book Description
The population of people with low vision is increasing. Services are needed to meet their needs for education and rehabilitation. Clinical measurements of vision do not correlate with how a person uses vision. Low-vision service in many developing countries is of recent origin. Many primary eye-care providers in developing countries may not understand the importance of low-vision rehabilitation service and do not carry out the functional vision assessment. Hence the functional vision assessment and developing visual efficiency depend on the educators and rehabilitation professionals. This book describes the vision assessment using simple techniques and functional vision assessment procedure. Visual efficiency, the ability to use vision effectively can be developed by instructional strategies and environmental adaptations. This book describes the techniques with illustrations. The use of optical devices may require a structured practice. The readers will understand that efficiency in the use of optical devices may help the low-vision childs academic success. This guide addresses that decision about reading medium of low-vision students is based on the structure of impairment and the sensory capabilities. The book also includes the educational needs of low-vision students. This book can be taken as a well-organized guide and textbook for teachers, researchers, parents, and low-vision persons themselves.

Vision Assessment: Shaping Technology in 21st Century Society

Vision Assessment: Shaping Technology in 21st Century Society PDF Author: John Grin
Publisher: Springer Science & Business Media
ISBN: 3642597025
Category : Technology & Engineering
Languages : en
Pages : 194

Book Description
One way to shape technology and its embedding in society in the 21st century is through the visions that guide their development, especially concerning the long-term societal perspective. A critical discussion and assessment of these visions is a prerequisite for influencing the course of development. Technology assessment, therefore, has to provide a methodological repertoire for assessing and constructing visions, taking into account the requirements for long-term orientation as well as the need for public legitimation. This volume draws upon insights from technology assessment, political sciences, epistemology, sociology and ethics. It is to contribute to the recent literature in on "shaping technology", taking into account the "co-evolution of technology and society". It connects to that technology assessment literature that emphasises TA's pro-active role and its contribution to political judgement.

Emergent Techniques for Assessment of Visual Performance

Emergent Techniques for Assessment of Visual Performance PDF Author: National Research Council
Publisher: National Academies Press
ISBN:
Category : Medical
Languages : en
Pages : 75

Book Description
Recent vision research has led to the emergence of new techniques that offer exciting potential for a more complete assessment of vision in clinical, industrial, and military settings. Emergent Techniques for Assessment of Visual Performance examines four areas of vision testing that offer potential for improved assessment of visual capability including: contrast sensitivity function, dark-focus of accommodation, dynamic visual acuity and dynamic depth tracking, and ambient and focal vision. In contrast to studies of accepted practices, this report focuses on emerging techniques that could help determine whether people have the vision necessary to do their jobs. In addition to examining some of these emerging techniques, the report identifies their usefulness in predicting performance on other visual and visual-motor tasks, and makes recommendations for future research. Emergent Techniques for Assessment of Visual Performance provides summary recommendations for research that will have significant value and policy implications for the next 5 to 10 years. The content and conclusions of this report can serve as a useful resource for those responsible for screening industrial and military visual function.

Cerebral visual impairment (also known as cortical visual impairment, or CVI) has become the most common cause of visual impairment in children in the United States and the developed world. Vision and the Brain is a unique and comprehensive sourcebook geared especially to professionals in the field of visual impairment, educators, and families who need to know more about the causes and types of CVI and the best practices for working with affected children. Expert contributors from many countries represent education, occupational therapy, orientation and mobility, ophthalmology, optometry, neuropsychology, psychology, and vision science, and include parents of children with CVI. The book provides an in-depth guide to current knowledge about brain-related vision loss in an accessible form to enable readers to recognize, understand, and assess the behavioral manifestations of damage to the visual brain and develop effective interventions based on identification of the spectrum of individual needs. Chapters are designed to help those working with children with CVI ascertain the nature and degree of visual impairment in each child, so that they can "see" and appreciate the world through the child's eyes and ensure that every child is served appropriately.
