INTRODUCTION: Intravitreal anti-vascular endothelial growth factor (VEGF) therapy has become the mainstay of treatment in many retinal diseases. The comparative efficacy and safety of newer bispecific anti-VEGF/angiopoietin 2 (Ang2) agents in the treatment paradigm versus widely used monospecific anti-VEGF agents remains unclear. METHODS: A systematic literature search of MEDLINE, Embase, and Cochrane Library was conducted to identify comparative observational studies and randomized controlled trials published from 2015 to Jul 2024. With assessment by three independent reviewers, original English peer-reviewed full-text articles evaluating faricimab versus monospecific anti-VEGF agent(s) in FDA-indicated retinal disease with data on at least one set of efficacy and/or safety outcomes for each treatment arm and a minimum 3-month follow-up period were included. Data were appraised using the Cochrane RoB2 and ROBINS-I tools, PRISMA, and Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) guidelines. All outcomes were collected at the last follow-up. Random effects meta-analyses with 95% confidence intervals were conducted to calculate weighted mean differences and risk ratios. Change in best-corrected visual acuity (BCVA, ETDRS letters), change in central subfield thickness (CSFT, μm), and presence of retinal fluid were primary endpoints; ocular adverse events were secondary endpoints. RESULTS: Across 13 studies, in the context of neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO), 2,226 eyes received anti-VEGF monotherapy and 3,022 received faricimab. Final and change in BCVA were similar between treatment groups. Faricimab was associated with a significantly higher reduction in CSFT in DME and RVO eyes but not in nAMD eyes. The incidence of ocular adverse events was similar between groups. CONCLUSION: There was no difference in BCVA between faricimab and anti-VEGF monotherapy in nAMD, DME, and RVO. While faricimab offered superior improvement in CSFT at the final follow-up for DME and RVO eyes, this effect was not seen in nAMD eyes. Future studies are needed to establish the long-term safety and efficacy of faricimab for retinal vascular disease.
