Abstract

To characterize the visual outcomes and the treatment course of patients with exudative age-related macular degeneration (AMD) based on ocular hypotensive use. A matched retrospective cohort study of patients enrolled in Kaiser Permanente Southern California health plan was conducted. Patients taking ocular hypotensives were identified using pharmacy dispensing data and were matched to controls to compare visual acuity, number of anti-VEGF injections, and conversation to secondary anti-VEGF agents in the first year of treatment. Subgroup analysis was performed based on the number of ocular hypotensive agents (0, 1, 2 or 3+ agents) and drug class (aqueous suppressants and prostaglandin analogs). A total of 234 patients patients were examined. Baseline and final visual acuity did not significantly differ between drop users and controls, including on subgroup analysis. The average number of anti-VEGF injections did not differ between drop users and controls (6.1 vs 6.2, p=0.97), nor did the percentage of patients who were switched to a second-line anti-VEGF agent (23.9% vs 17.9%, p=0.26). Subgroup analysis did not reveal significant differences in the number of anti-VEGF injections and the percentage of patients switched to second...Continue Reading
