This article reports on a study of the methods that 21 ophthalmologists used to assess the visual acuity of children with multiple impairments and the difficulties they encountered. Additional means of assessing visual function and alternative means of communicating the results are suggested. (Author/DB)

Techniques used by the Special Visual Assessment Clinic for the Handicapped at the University of California-Berkeley School of Optometry are designed to serve handicapped children and adults generally considered "difficult to assess." This article describes the clinic's assessment goals, clientele, and methods for assessing visual ability and…

Twenty-four congenitally visually handicapped infants, aged 6-24 months, participated in a study to determine (1) those stimuli best able to elicit visual attention, (2) the stability of visual acuity over time, and (3) the effects of binaural sensory aids on both visual attention and visual acuity. Ss were dichotomized into visually handicapped…

Background: The prevalence of visual impairments in people with severe and profound multiple disabilities (SPMD) is the subject of considerable debate and is difficult to assess. Methods: In a typical Dutch care organization, all clients with SPMD (n = 76) participated in the study and specific instruments adapted to these clients (requiring a…

Researched by means of a vision test of 60 normal and 60 educable mentally handicapped (EMH) children of elementary school age was the possibility that previously unidentified sensory disorders may be responsible for the observed underachievement of EMH children. (DB)

A study examined detailed data on 100 consecutive Special Populations Assessment and Rehabilitation Center patients and found the program to be successful in conducting interdisciplinary visual evaluations of those with multiple impairments. The types of adaptive-testing procedures used for visual acuity and visual field testing are described. (CR)

This study found that, of 18 children with severe visual and multiple impairments assessed using the Acuity Card Procedure (originally developed for assessing the visual acuity of infants), 42 percent responded. A similar group received a simple instructional intervention prior to testing and that group's response rate was 85 percent. (Author/DB)

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 describes addition of a "learn a routine" procedure to functional visual assessments of children with severe neurological and physical disabilities. The procedure capitalizes on the child's interest of the moment and provides information on the child's patterns of responses, ability to accommodate to variations of a stimulus, and…

Vision assessment in multiply impaired children (ages 3-19, n=50) was studied by evaluating questionnaires completed by the psychological services responsible for determining their educational requirements. Relatively few conducted assessments of visual functioning but chose instead to determine level of visual impairment from medical,…

Data elicited by two questionnaires on the characteristics (numbers, nature, extent, and location) of the multihandicapped population under 21 years of age in California are presented. Based on replies by 613 programs (47% response) and estimated to include 80 to 90% of the state's multihandicapped blind children, statistics concern…
