THE FOLLOWING IS THE FULL TEXT OF THIS DOCUMENT: Video visual aids are Closed Circuit TV systems (CCTV's) which magnify print and enlarge it electronically upon a screen so partially sighted persons with some residual vision can read and write normal size print. These devices are in use around the world in homes, schools, industries and libraries,…

Five considerations for determining the most appropriate learning medium for students with functional vision are: (1) working distance from the page; (2) portability of reading skills; (3) reading rates and accuracy; (4) visual fatigue; and (5) interpretation of assessment results. (Author/DB)

This article describes the physiological mechanisms involved in three-dimensional depth perception and presents a variety of distance and depth cues and strategies for detecting and estimating curbs and steps for individuals with impaired vision. (Author/DB)

Provides practical advice for the teacher on helping the visually impaired child succeed in the regular classroom. Includes consideration of classroom and materials, adaptations, special subjects, such as physical education, and interpersonal issues. (SJL)

This article presents a practical guide to help professionals develop techniques and materials that motivate preschool-age children to learn to use low vision devices. Skills for optical-device training and sample training activities for monocular and magnifier use are outlined. (Author/DB)

A visually impaired rehabilitation teacher describes a model developed in Maine for providing low vision services, with emphasis on teaching the use of near-point aids to assist on near-point tasks. The article addresses preevaluation services, assessment of clients with low vision, and follow-up when the client begins using the aids at home. (DB)

Three experiments examined the ability of blind individuals and individuals simulating the visual acuity of 20/400 to monitor the behaviors of a cane traveler in various environments and at distances between 10 feet and 25 feet. Results suggested that at least some vision is needed for instructors monitoring visually impaired individuals learning…

To develop a battery of tasks to predict and improve mobility performance, a series of functional vision tasks (texural shearing, degraded images, embedded figures, and parafoveal attention) were generated by a microcomputer. Sixty visually impaired subjects given either computerized task training or real-life training improved their low vision…

The article describes a sequential training curriculum in the use of telescopic visual aids. The curriculum covers 29 topics, including aid maintenance, holding aid properly, focusing, scanning, target location, tracking, aid use for city bus travel, in a shopping center, and in a fast food type restaurant.

This article reviews some of the existing technology that assists children with low vision in their ability to use environmental cues. It provides recommendations for modification of color and contrast, illumination, space, and time. A chart lists technological assists for environmental cues and vendor information. (Contains references.) (CR)

A comprehensive program of instruction in the use of low vision is proposed, including definitions, a philosophy of low vision, theoretical constructs, a flow chart of professional and individual relationships and responsibilities, goals, curriculum, and an evaluation system. (Author/JDD)

The article presents a two-phase process for use by multidisciplinary teams making decisions on the reading medium for students with visual impairments. The first phase is a diagnostic teaching phase to guide initial decision making. The second phase, continued evaluation, leads to ongoing adjustment of the selected medium or media. (Author/DB)

The Low Vision Service of Perkins School for the Blind (Massachusetts) developed a model project to provide comprehensive vision evaluations and follow-up services to 169 children with dual sensory impairments throughout New England. This article describes the project's objectives, the population served, and the procedures for implementing…

The visual acuity of 8 children, aged 2-7, with low vision and multiple handicaps was effectively tested using the Teller Acuity Cards and a preferential-looking procedure with operant modification. This inexpensive procedure was found to be suitable for at-home testing by itinerant vision specialists in developing countries or rural areas. (DB)

This article considers the visual rehabilitation of patients recovering from traumatic brain injuries. Characteristics, symptoms, and associated neuromotor difficulties of posttrauma vision syndrome are listed, as are common posture and gait adaptations. A neuro-optometric rehabilitative and orientation/mobility evaluation is recommended, as is…
