Peer reviewedAitken, S.; Buultjens, M. – Journal of Visual Impairment and Blindness, 1991
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)

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…

Peer reviewedSchanel-Klitsch, Eileen; Ciner, Elise B.; Appel, Sarah; Graboyes, Marcy – RE:view, 1999
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)

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…

Peer reviewedGeruschat, D. R. – Journal of Visual Impairment and Blindness, 1992
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)

Peer reviewedSchanel-Klitsch, E. – Journal of Visual Impairment and Blindness, 1992
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)
