Treat-and-extend dosing of intravitreal anti-VEGF agents in neovascular age-related macular degeneration: a meta-analysis.

ABSTRACT: Intravitreal injections of antiangiogenic agents are pivotal in treating neovascular age-related macular degeneration (nAMD). The comparative efficacy and safety of treat-and-extend (T&E) versus bimonthly, monthly, and pro re nata (PRN) dosing remains unclear. A systematic review and meta-analysis of English-language RCTs reporting on efficacy and/or safety outcomes of dosing regimens of anti-VEGF agents in nAMD was performed. Best-corrected visual acuity (BCVA, ETDRS letters) at last follow-up represented the primary endpoint, while central subfield thickness (CSFT, μm), injection burden, and ocular adverse events were secondary endpoints. A random effects meta-analysis was performed, and 95% confidence intervals were calculated. Across six RCTs, 781 T&E-, 663 monthly-, 130 PRN-, and 123
