• We compared the visual acuity of 89 patients obtained via a telephone interview with visual acuity elicited from the same patients in an ophthalmologist's office. Agreement within one line of vision between the telephone interview, in which patients used a modified Rosenbaum near card with attached patch, and the clinic near vision test was observed in 91% of eyes, while agreement within one line of vision between the telephone interview and clinic distance vision test was found in 86% of eyes. We conclude that testing visual acuity via a telephone interview is a potentially useful approach to assessment of visual acuity and prevalence of visual impairment in the larger population.
