Objective: To assess the impact of best-eye and worst-eye visual acuity (BEVA and WEVA, respectively) on health-related quality of life and utility in patients with wet age-related macular degeneration.
Design: This cross-sectional, prospective, observational, multicenter study was performed in France, Germany, and Italy. Patients were stratified into 4 severity groups (BEVA, 20/40; WEVA, 20/200). Patients completed the National Eye Institute 25-Item Visual Function Questionnaire, the Macular Disease Quality of Life Scale, and the Health Utility Index 3. Analysis of variance was used to adjust for age, sex, and country.
Results: Patients (N = 360) were mainly female (59.6%), with a mean age of 77 years and mean time since age-related macular degeneration diagnosis of 2.3 years. Health Utility Index 3 scores decreased with VA severity from 0.62 to 0.39. The National Eye Institute 25-Item Visual Function Questionnaire global score decreased with VA severity from 67.0 to 40.7 and was related to the BEVA (P < .001) and WEVA (P = .03). Corresponding changes were observed on the general vision, distance vision, driving, and mental health dimensions. The average weighted impact score on the Macular Disease Quality of Life varied from -4.6 to -2.6, decreasing with VA severity. Both eyes contributed to the average weighted impact score.
Conclusion: The BEVA and WEVAs influenced vision-related quality of life independently, as measured by the National Eye Institute 25-Item Visual Function Questionnaire and Macular Disease Quality of Life Scale.
