Because most patients with low vision are older and have functional limitations from other health problems that could add to the functional limitations caused by their visual impairments, Goldstein and colleagues identify factors associated with visual ability measures among new patients of a prospective observational study seeking outpatient low vision rehabilitation services. Patients (N = 779) from 28 US clinical centers completed an adaptive visual function questionnaire and other questionnaires. Correlations were observed between visual acuity and baseline visual ability overall (r = −0.42) and across the 4 functional domains evaluated. The authors concluded that visual ability is a multidimensional construct, with visual acuity, depression, physical ability, and cognition explaining more than one-third of the variance in visual ability as measured by these questionnaires.
