Abstract
PURPOSE: The aim of this study was to compare the effects of ranibizumab to those of bevacizumab during the treatment of neovascular age-related macular degeneration (AMD) with an incomplete posterior vitreous detachment. DESIGN: A retrospective chart review. METHODS: A retrospective chart review was performed on treatment-naive neovascular AMD subjects with an incomplete posterior vitreous detachment treated with either ranibizumab or bevacizumab over a 12-month period. RESULTS: One hundred thirty subjects were analyzed. There were 49 subjects determined to have vitreous attachment to the fovea. Subjects with vitreous attachment to the fovea required a significantly greater number of injections during the study interval compared with those without (10.2 ± 0.75 vs 7.8 ± 0.62) (P < 0.0001). In subjects with vitreous attachment to the fovea, the ranibizumab cohort had a greater improvement in visual acuity (0.18 ± 0.1 vs 0.04 ± 0.11 logMAR) (P = 0.0176) and a greater reduction in macular thickness (93.4 ± 32.2 μm vs 30.3 ± 28.3 μm) (P = 0.0064) compared with the bevacizumab cohort. CONCLUSIONS: Neovascular AMD patients with vitreous attachment to the fovea may have better visual and anatomic outcomes when treated with ranibizumab compared with bevacizumab.
