EFFECTIVENESS OF DIFFERENT MONITORING MODALITIES IN THE DETECTION OF NEOVASCULAR AGE-RELATED MACULAR DEGENERATION: The Home Study, Report Number 3.

ABSTRACT

PURPOSE: To determine the effectiveness of different monitoring modalities to detect incident neovascularization associated with age-related macular degeneration (AMD). METHODS: Secondary analyses compared the rates of detecting incident neovascular AMD in prescheduled office visits versus office visits triggered by monitoring device or by symptom realization in a randomized trial evaluating home telemonitoring device plus standard care (device arm) versus standard care alone. RESULTS: At prescheduled office visits, neovascular AMD was detected in 14/1927 visits (0.7%, 95% confidence interval [CI] 0.4%-1.1%) and 14/1949 visits (0.7%, 95% CI 0.3%-1.1%) in the device and standard care alone arms, respectively. Thirty-seven participants with neovascular AMD were detected in 318 office visits (11.6%, 95% CI 8.1%-15.2%) triggered by device or symptom realization and 17 neovascular AMD in 65 office visits (26%, 95% CI 15.5%-36.8%) triggered by symptom realization in the device and standard care alone arms, respectively. The home device strategy had a higher neovascular-AMD detection rate than prescheduled office visits (relative risk = 16.0 [95% CI 8.8-29.3]). Neovascular AMD detected at triggered visits were associated with less vision loss from baseline in the device arm versus standard care alone arm (-3 letters vs. -11.5 letters, respectively, P = 0.03). CONCLUSION: Telemonitoring may alter the management of patients with AMD and improve vision outcomes.
