Abstract
OBJECTIVE: To evaluate the validity of the Activities of Daily Vision Scale (ADVS) as a tool to assess fall risk in older adults with vision impairment. DESIGN: Cross-sectional assessments of visual function and retrospective collection of fall data. SETTING: The outpatient medical clinics of an academic tertiary care community hospital. PARTICIPANTS: Randomly selected sample (n = 143) of older (> or = 65 years) patients seen at the outpatient medical clinics at Nassau County Medical Center in Long Island, New York. These patients had one or more of five ocular conditions: refractive errors (n = 90), cataracts (n = 77), glaucoma (n = 29), diabetic retinopathy (n = 19), and/or macular degeneration (n = 6). MEASUREMENTS: Visual function, assessed using the ADVS, demonstrated scores ranging from 0 (marked visual disability) to 100 (no visual difficulty). Fall history and the presence of eye disease were based on the self-recall of patients. Fall history was assessed retrospectively over a 1-year period from the time of the interview. RESULTS: Thirteen percent of the subjects reported having one or more falls during the 1-year period before the time of the interview. These subjects scored significantly lower on the ADVS compared with the scores of the group that did not report falls (74 +/- 22 vs 85 +/- 14, P < .01). Using a cutoff score of 90 points (10% loss of visual function on the ADVS), the ADVS had a 67% sensitivity in identifying those patients who had falls. Among the patients with glaucoma and those with diabetic retinopathy, the ADVS had a 100% sensitivity in identifying those patients who reported a history of falls. In patients with cataracts and refractive errors, the ADVS had a sensitivity of 82% and 64%, respectively, in identifying patients with a history of falls. The number of falls reported by the subjects showed no relationship with the ADVS scores. CONCLUSION: The results from this study suggest that the ADVS may prove to be a useful tool to assess fall risk in older adults with vision impairment, especially in those persons with glaucoma, diabetic retinopathy, and/or cataracts.
