Longer-Term Anti-VEGF Therapy Outcomes in Neovascular Age-Related Macular Degeneration, Diabetic Macular Edema, and Vein Occlusion-Related Macular Edema

PURPOSE: The clinical practice visual acuity (VA) outcomes of anti-VEGF therapy for up to 5 years were assessed in patients with neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), branch retinal vein occlusion-related macular edema (BRVO-ME), and central retinal vein occlusion-related macular edema (CRVO-ME). DESIGN: A retrospective analysis was performed using the Vestrum Health Retina Database. PARTICIPANTS: Treatment-naive patients with nAMD, DME, BRVO-ME, or CRVO-ME who received anti-VEGF injections between 2014 and 2019 and had follow-up data for ≥12 months. METHODS: Data on age, sex, the number of anti-VEGF treatments, and VA were analyzed. MAIN OUTCOME MEASURES: Mean VA change up to 3 years (BRVO-ME and CRVO-ME) and 5 years (nAMD and DME). RESULTS: At 1, 3, and 5 years, in 67 666, 21 305, and 5208 eyes with nAMD, after a mean of 7.6, 19.5, and 32 injections, there was a mean change of +3.1, -0.2, and -2.2 letters, respectively. At 1, 3, and 5 years, in 40 832, 7728, and 1192 eyes with DME, after a mean of 6.2, 15.4, and 26.0 injections, there was a mean change of +4.7, +3.3, and +3.1 letters, respectively. At 1 and 3 years, in 12 451 and 3027 eyes with BRVO-ME, after a mean of 7.1 and 18.2 injections, there was a mean change of +9.5 and +7.7 letters, respectively. At 1 and 3 years, in 9298 and 2264 eyes with CRVO-ME, after a mean of 7.3 and 18.8 injections, there was a mean change of +8.3 and +6.0 letters, respectively (P 1 letter). In all 4 conditions, the mean VA increased with the mean number of anti-VEGF injections, eyes with a baseline VA of 20/40 or better tended to lose VA, and eyes with progressively worse baseline VA experienced a progressively greater VA gain at 3 years. CONCLUSIONS: In practice, patients with nAMD, DME, BRVO-ME, and CRVO-ME showed limited visual outcomes, with patients with nAMD tending to lose VA at 3 and 5 years. Across all 4 disorders, the mean change in VA correlated with treatment intensity at 1, 3, and 5 years. Patients with better baseline VA are more vulnerable to vision loss.
