Objectives To characterize the pattern of approved anti-vascular endothelial growth factor (VEGF) treatments among patients with neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME) in the United Arab Emirates (UAE). Method This was a retrospective, nonrandomized, observational cohort analysis of the Dubai Real-world Claims Database with a 360-day follow-up period. Adult patients diagnosed with nAMD or DME treated with ranibizumab or aflibercept for the first time were included. The primary objective was to evaluate anti-VEGF treatment patterns with respect to the proportion of patients receiving ranibizumab and aflibercept for nAMD and DME separately. Results Of the 451 patients included in the final study cohort, 83.6% and 16.4% had a diagnosis of DME (ranibizumab: 48.5%; aflibercept: 51.5%) and nAMD (ranibizumab: 40.5%; aflibercept: 59.5%), respectively, at baseline. Treatment frequency of ranibizumab/aflibercept was similar for nAMD (mean: 2.4/2.9 injections; p = 0.2389) with fewer injections in the ranibizumab cohort for DME (mean: 1.9/2.5 injections; p = 0.0002). Most patients received ≤3 anti-VEGF injections during the 360-day follow-up period. The time between consecutive treatments was large (nAMD: 73.6 days/10.5 weeks; DME: 80.5 days/11.5 weeks). Approximately 10%–13.5% of patients switched their anti-VEGF therapy. Most patients (83.8%) had a diabetes diagnosis during the follow-up period. Conclusions This real-world study provides an initial understanding of anti-VEGF treatment patterns in patients with nAMD and DME in the UAE. Treatment frequency of the 2 anti-VEGF agents assessed was similar in both patient populations. Both treatments were infrequently administered with large dosing intervals.
