Foundations of Low Vision


Book Description

Foundations of Low Vision: Clinical and Functional Perspectives, the ground-breaking text that highlighted the importance of focusing on the functional as well as the clinical implications of low vision, has been completely updated and expanded in this second edition. The revised edition goes even further in its presentation of how best to assess and support both children and adults with low vision and plan programs and services that optimize their functional vision and ability to lead productive and satisfying lives, based on individuals' actual abilities. Part 1, Personal and Professional Perspectives, provides the foundations of this approach, with chapters focused on the anatomy of the eye, medical causes of visual impairment, optics and low vision devices, and clinical low vision services, as well as psychological and social implications of low vision and the history of the field. Part 2 focuses on children and youths, providing detailed treatment of functional vision assessment, instruction, use of low vision devices, orientation and mobility, and assistive technology. Part 3 presents rehabilitation and employment issues for working-age adults and special considerations for older adults.




Occupational Therapy Interventions for Adults with Low Vision


Book Description

The purpose of this textbook is to define and describe the occupational therapy approach to low vision rehabilitation using the Occupational Therapy Practice Framework, 2nd ed. (AOTA, 2008) as the guide to evaluation and intervention. Although this textbook focuses on the older adult with acquired age-related vision loss, the principles of low vision rehabilitation are applicable to all ages.




Low Vision Rehabilitation


Book Description

Presents an emerging model in which occupational therapists practice as part of a team of vision rehabilitation professionals serving adults with low vision. Occupational therapists offer a unique contribution to the vision rehabilitation team, with a focus on meaningful occupational goals, the incorporation of occupation into therapy, and the orchestration of environmental, social, and non-visual personal factors into a treatment plan. The authors have developed a practical and straightforward text outlining an evaluation approach to interventions that focus on recovering occupational performance in adults.




Psychophysics of Reading in Normal and Low Vision


Book Description

Written by a leader in the field, this book discusses the role of vision in reading. The author describes the influence of physical properties of text on reading performance and the implications for information processing in the visual pathways. He explores different forms of low vision that affect reading, text characteristics that optimize reading for those with low vision, principles underlying the legibility of text, and guidelines for displaying text. Special topics include the role of the magnocellular pathway in reading and dyslexia, Braille reading, and fonts for highway signs. An accompanying CD contains reprints of the seminal series of articles by Gordon E. Legge and colleagues published between 1985 and 2001.




Low Vision Manual


Book Description

.this book represents a real milestone for low vision care because it is one of the first low vision books in the world, and the first from the UK, that doesn't just give lip service to multi-disciplinary collaboration- it has a multi-disciplinary authorship. Barbara Ryan, Research Associate, School of Optometry and Vision Sciences, Cardiff University, Cardiff, UK Low Vision Manual is a comprehensive guide and up-to-date reference source, written by clinical and research experts in the fields of disease detection and management; primary and secondary optometric care; low vision optics and prescribing; counselling and rehabilitation. All these areas are explored in this book in four key sections: Section One: Definition of low vision and its epidemiology Section Two: The measurement of visual function of the visually impaired Section Three: The optics and practical tips on prescribing low vision aids Section Four: Rehabilitation strategies and techniques This is an important reference tool for all professionals involved with the visually impaired. The book covers everything a practitioner will need on a day-to-day basis. Clear layout with practical tips, worked examples and practical pearls will enable the front-line eye-care professional to provide patients with sound, research-based clinical care and rehabilitation.

Assistive Technology for Blindness and Low Vision


Book Description

Assistive technology has made it feasible for individuals with a wide range of impairments to engage in many activities, such as education and employment, in ways not previously possible. The key factor is to create consumer-driven technologies that solve the problems by addressing the needs of persons with visual impairments. Assistive Technology for Blindness and Low Vision explores a broad range of technologies that are improving the lives of these individuals. Presenting the current state of the art, this book emphasizes what can be learned from past successful products, as well as what exciting new solutions the future holds. Written by world-class leaders in their field, the chapters cover the physiological bases of vision loss and the fundamentals of orientation, mobility, and information access for blind and low vision individuals. They discuss technology for multiple applications (mobility, wayfinding, information access, education, work, entertainment), including both established technology and cutting-edge research. The book also examines computer and digital media access and the scientific basis for the theory and practice of sensory substitution. This volume provides a holistic view of the elements to consider when designing assistive technology for persons with visual impairment, keeping in mind the need for a user-driven approach to successfully design products that are easy to use, well priced, and fill a specific need. Written for a broad audience, this book provides a comprehensive overview and in-depth descriptions of current technology for designers, engineers, practitioners, rehabilitation professionals, and all readers interested in the challenges and promises of creating successful assistive technology.




Access Technology for Blind and Low Vision Accessibility


Book Description

"Access Technology for Blind and Low Vision Accessibility, the second edition of 2008's Assistive Technology for Students Who Are Blind or Visually Impaired: A Guide to Assessment, uses clear language to describe the range of technology solutions that exists to facilitate low vision and nonvisual access to print and digital information. Part 1 gives teachers, professionals, and families an overview of current technologies including refreshable braille displays, screen readers, 3D printers, cloud computing, tactile media, and integrated development environments. Part 2 builds on this foundation, providing readers with a conceptual and practical framework to guide a comprehensive technology evaluation process. As did its predecessor, Access Technology for Blind and Low Vision Accessibility is focused on giving people who are blind or visually impaired equal access to all activities of self-determined living, allowing them to be seamlessly integrated within their home, school, and work communities"--




Cortical Visual Impairment


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.
