Neovascular age-related macular degeneration (NVAMD) is the most common cause of uncorrectable vision loss among the elderly in developed countries. Bevacizumab and ranibizumab are the most frequently used anti–vascular endothelial growth factor (VEGF) agents injected intravitreally to treat NVAMD.
For this systematic review, we included only randomized controlled trials in which the 2 anti-VEGF agents had been compared directly. The primary outcome was 1-year gain in best-corrected visual acuity (BCVA) of ≥15 letters. We followed Cochrane methods for trial selection, data extraction, and data analyses. Relative effects of bevacizumab versus ranibizumab are presented as estimated risk ratios (RRs) and mean differences (MDs) with 95% confidence intervals (CIs).
We identified 6 eligible randomized controlled trials with 2809 participants. The proportion of eyes that gained ≥15 letters of BCVA by 1 year was similar for the 2 agents when the same regimens were compared (RR, 0.90; 95% CI, 0.73–1.11). The mean change in BCVA from baseline also was similar (MD, −0.5 letter; 95% CI, −1.6 to +0.6). Other BCVA and quality of life outcomes were similar for the 2 agents. One-year treatment cost with ranibizumab was 5.1 and 25.5 times the cost for bevacizumab in the 2 largest trials. Ocular adverse events were uncommon (<1%), and rates were similar for the 2 agents.
We found no important difference in effectiveness or safety between bevacizumab and ranibizumab for NVAMD treatment, but there was a large cost difference.
