Capabilities and limitations of severely visually impaired persons were assessed to learn how they are organized and influenced. Data representing a range of visual environmental adaptation problems were collected from a sample of 251 applicants to a comprehensive low vision clinic. Factorial analyses indicated that problems can be grouped on the basis of eight functional domains, among which an independent living skills factor accounted for most response variance. Major influences on outcomes in these domains are acuity, sex, age, education, and perceived impact of impairment on quality of life. Results suggested the usefulness of rehabilitation programs geared to activity domains rather than to vision parameters.
