Functional implications of vision impairment.
This study investigated the functional implications of vision impairment. A total of 508 participants in the Visual Impairment Project completed the VF-14 questionnaire, vision-related functional tasks, an interview, and the ophthalmic examination. Participants with less than 6/12 presenting acuity were more likely to report a moderate to high degree of difficulty performing VF-14 items (odds ratios from 6 to 44). They were also more likely to be unable to recognize a 10 cent coin (OR; 7.0, 95% CL; 2.6, 19.3) or correctly read a telephone number (OR; 10.1, 95% CI; 5.6, 18.1). As demonstrated by the VF-14 and the functional tasks administered in this study, visual impairment affects the ability of people to conduct a variety of common daily tasks.
