Making Choices in Functional Vision Evaluations: “Noodles, Needles, and Haystacks”
Functional vision evaluations are appropriate components of the special assessments for visually handicapped children and youth. The best procedures are sometimes difficult to select, however, because of the wide range in age, ability, and visual status of the subjects. This paper offers an organized approach to performing functional vision evaluations by clarifying the types of data collection and by suggesting protocols for three broad categories of subjects: “normal” visually handicapped students of school age, “normal” preschool visually handicapped children, and multiply handicapped/visually handicapped pupils. Infants with visual impairments are classified with multiply handicapped children, since the procedures for evaluation are similar.
