Computer use among patients with age-related macular degeneration.

PURPOSE: Age-related macular degeneration (AMD) is the leading cause of incurable vision loss in older adults in industrialized countries and is on a trajectory to disable a growing number of persons as societies age. To assess the potential of using telemedicine for expansion of an in-person AMD self-management program, we examined the extent of computer use in a sample of older adults with AMD. METHODS: 160 older adult volunteers (mean age = 76 years; female = 51%) with AMD (mean visual acuity in better eye: 20/40; worse eye: 20/90) were randomly selected from members of the San Diego County AMD Registry. Computer use was assessed with a Health and Impact Questionnaire. Dependent measures were Snellen visual acuity, National Eye Institute-Visual Function Questionnaire, the AMD Self-Efficacy Questionnaire, and the Geriatric Depression Scale. RESULTS: Overall 70.6% reported computer use at least once per month. By age and gender stratum, 76.5% of men aged 60-74 years, 73.3% of men aged 75 years and over, 74.3% of women aged 60-74 years, and 60.9% of women aged 75 years and over used computers. In logistic regression analyses controlling for age and gender, computer use was associated with better visual acuity (P = 0.029), higher education (P = 0.002), and self-efficacy for communication (P = 0.027). CONCLUSION: The majority of older adults with AMD in our sample used computers, with use highest among more educated and visually intact patients. Computer use to access the Internet is feasible in AMD patients and should be encouraged. The inclusion of computer use in measures of AMD-related functioning appears warranted.

Treatment of depression associated with age-related macular degeneration: a double-blind, randomized, controlled study.

BACKGROUND: Depression is frequently found in patients with age-related macular degeneration (AMD). The purpose of this study was to assess the effectiveness of escitalopram in treating major and minor depression in AMD patients. METHODS: We conducted a crossover, randomized, double-blind, placebo-controlled, 16-week study comparing escitalopram with placebo. Inclusion criteria included reduced vision from AMD and major or minor depression, with a 17-item Hamilton Rating Scale for Depression (HAMD-17) score of ≥10. Participants were randomly assigned to receive either escitalopram or placebo for 8 weeks and then crossed over to the other treatment. The primary outcome was change on the total HAMD-17 score with escitalopram treatment compared with placebo. RESULTS: We enrolled 16 AMD patients (mean age 79.1), 12 with major depression and 4 with minor depression. Mean HAMD-17 score at enrollment was 16.1 ± 4.2, and mean visual acuity in the better eye was 20/70. During escitalopram treatment, participants showed a significant reduction in HAMD-17 scores compared with placebo treatment (P = .01). CONCLUSIONS: These findings suggest escitalopram may be an effective treatment for depressive symptoms associated with major or minor depression in AMD patients with vision loss.
