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…

Techniques for evaluating the multiply impaired child's functional level of vision are described and a sequence of visual stimulation instruction for children with visual impairments is presented. (PHR)

The study evaluated the validity, reliability, and effectiveness in providing needed information of the Montana Functional Vision Assessment (MFVA) Instrument by comparing it with the Texas Education Agency Functional Vision Assessment and field testing the instrument in evaluations of nine multihandicapped students (ages 3-11). Evaluation led to…

A screening program for vision problems and Usher's Syndrome (a common cause of deaf-blindness) among 210 hearing-impaired students found 44 percent had significant vision problems and 1 percent had Usher's Syndrome. The program involved an interagency network of school, health care, and support personnel and utilized a dilated ophathalmological…

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…

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 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…

Research and application of principles of behavior modification with visually impaired and blind children are reviewed with particular attention to lower functioning multiply impaired children. (Author)

Vision problems occur at higher rates in the deaf and hearing impaired population than in the general population. When an individual has a hearing impairment, vision becomes more significant in the instructional and learning process, as well as in social and communicative exchanges. Regular comprehensive visual screening of hearing impaired…

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)

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,…

This book describes transdisciplinary management of multiply disabled children with vision problems and presents four theoretical models of visual assessment and three illustrative case studies in a sequence appropriate to the learning process. The first three models are intended to lead to assessment and management of the child and the last to…

A set of developmental norm data for reflexive and voluntary visual-motor development was compiled, revised after extensive clinical use, and found to have highly significant interrater agreement. Use of the resultant Erhardt Developmental Visual Assessment is illustrated with a multiply handicapped three-year-old. (Author/JDD)
