Abstract
PURPOSE: To compare the 12-month treatment outcome of ranibizumab with that of aflibercept in cases of neovascular age-related macular degeneration (AMD). METHODS: This retrospective single-institution study included patients who had been diagnosed with treatment-naïve neovascular AMD and treated using either ranibizumab (ranibizumab group, n = 30) or aflibercept (aflibercept group, n = 21) monotherapy over a 12-month follow-up period. Patients initially received three monthly injections, and were re-treated when neovascularization recurred. The best-corrected visual acuity (BCVA) at diagnosis and at 12 months, as well as the number of injections, were compared between the two groups. RESULTS: In the ranibizumab group, the mean logarithm of the minimum angle of resolution BCVA values at diagnosis and at 12 months were 0.86 ± 0.45 and 0.72 ± 0.56, respectively. The equivalent values were 0.73 ± 0.37 and 0.58 ± 0.41 in the aflibercept group. The mean number of injections was 4.5 ± 1.3 in the ranibizumab group and 4.3 ± 0.9 in the aflibercept group. There was no difference in BCVA between the two groups at either diagnosis (P = 0.560) or 12 months (P = 0.702). There was also no difference between the two groups in the number of injections (P = 0.847). CONCLUSION: The 12-month treatment outcome of intravitreal ranibizumab was similar to that of intravitreal aflibercept, with a comparable injection frequency. Further prospective studies with a more controlled design are needed to confirm our findings.
