This review aims to document the efficacy and validity of vision therapy for modifying and improving vision functioning. The paper describes the essential components of the visual system and disorders which can be physiologically and clinically identified. Vision therapy is defined as a clinical approach for correcting and ameliorating the effects…

The challenges of after-dark travel for low vision children are examined in terms of physical effects of low light on normal and abnormal vision and consequences for low vision travel and orientation skills. Techniques for efficient vision use are suggested along with night travel aids and considerations in night driver vision. (CL)

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,…

The article orients the reader to numerous aspects of low vision aids, including types of aids, function of aids, training sequence and considerations, a non-technical description of visual acuity, and favorable prognostic factors in using low vision aids. A brief annotated resource list is included. (Author)

The article suggests recommended student competencies for students using low vision devices at preschool, elementary, and secondary levels. It also presents an extensive bibliography on low vision aids for special educators. (DB)

Standards are presented for self evaluation of low vision services as part of the National Accreditation Council accreditation program. Participants rank their services on a scale from excellent to minimal for the following areas: planning and organization, personnel, low vision evaluation, continuing services, facilities and equipment, and…

The authors describe the function of a low vision clinic and report on an evaluation of one clinic's services. (Author)

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)

The final report describes a project to facilitate the efficiency with which legally blind persons use their remaining vision. The project developed a diagnostic assessment procedure, a design for instruction which includes 150 sequenced lessons, and a sourcebook on low vision. The reliability and validity of the diagnostic assessment procedure…

Low vision services to help visually impaired students maximize their use of residual vision are provided through a multidisciplinary regional clinic team in a sparsely populated area of Texas. Workups give classroom teachers information on techniques and optical aids. (CL)

Elementary partially sighted students read significantly more total books and school books using the Visolett (a low vision aid) than using large print text books, and the junior high partially sighted students read significantly more total pages using the Visolett. (Author/CL)

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)

This study of the effects of lenses of different colors on the visual abilities and comfort of 20 patients with retinal disease found that, in home trials, the critical issue was density more than color. Office tests of visual acuity and contrast sensitivity with colored lenses did not predict subjective benefit. (Author/JDD)
