Aim: To compare the efficacy and safety of bevacizumab versus ranibizumab in the treatment of patients with neovascular age-related macular degeneration (AMD).
Patients and methods: Retrospective case-controlled series of 30 patients treated with intravitreal bevacizumab and 28 patients treated with intravitreal ranibizumab for exudative AMD. Main outcomes measured included best-corrected visual acuity (BCVA), central macular thickness (CMT) and foveal thickness, quantity of subretinal fluid, neovessel size and total number of injections over the first year treatment period. A secondary outcome was the report of any adverse events in both groups.
Results: BCVA stabilized and increased from LogMAR 0.70 to 0.47 in the bevacizumab group and from 0.55 to 0.54 in the ranibizumab group (P>0.05). CMT decreased in the bevacizumab group from 369 to 284 μm and in the ranibizumab group from 340 to 271 μm (P>0.05). The number of injection was significantly lower (4.8) in the bevacizumab group than in the ranibizumab group (5.8) (P<0.05). No serious ocular adverse events were noted in both groups.
Conclusion: This retrospective study failed to show a difference in visual and anatomic outcomes between bevacizumab and ranibizumab. The number of re-treatment was lower in the bevacizumab group (P=0.03).
