Abstract

Purpose: To evaluate the efficacy and safety of different agents, dosages and strategies of anti-vascular endothelial growth factor (VEGF) treatment for neovascular age-related macular degeneration (nAMD) by network meta-analysis.

Methods: Electronic database searches were conducted on PubMed, Embase and Cochrane Central Register of Controlled Trials up to 1 December 2019 to `identify relevant randomized controlled trials (RCTs). The standardized mean difference (SMD), odds ratios (OR), 95% confidence intervals (CI), the surface under the cumulative ranking curves and the mean ranks of each outcome were estimated by Stata 14.0.

Results: Forty-seven RCTs encompassing 17 872 nAMD patients randomly assigned to 36 regimens of anti-VEGF agents or sham treatment were included. T&E strategy shows top-level effect both in BCVA changes and the percentage of patients with a gain of 3 lines or more of BCVA. When taking the same strategy, there is no significant difference of efficacy among ranibizumab, bevacizumab and aflibercept (p > 0.05); The combination of radiation, topical NSAIDs and photodynamic therapy (PDT) might provide additional benefit in central retinal thickness (CRT) reduction; all these therapeutic regimens of different anti-VEGF agents do not significantly increase the risk of severe ocular or cardiocerebral vascular adverse events (ADEs) compared with sham treatment (p > 0.05).

Conclusions: T&E strategy showed a satisfactory effect in visual improvement and there is no significant difference in efficacy or safety among ranibizumab, bevacizumab and aflibercept. All the included regimens have an acceptable risk of ADEs.
