Introduction: The aim of this study was to investigate the safety and efficacy of a single injection of intravitreal faricimab (IVF) in patients with neovascular age-related macular degeneration (nAMD) who had a prior treatment history.
Methods: A retrospective analysis was conducted on a consecutive cohort of 80 eyes of 75 patients with nAMD who had a prior history of treatment with an injection of anti-vascular endothelial growth factor. Best-corrected visual acuity (BCVA), central subfield thickness (CST), and central choroidal thickness (CCT) were compared before the initial IVF injection and after a treatment interval matching the previous duration.
Results: Central choroidal thickness decreased significantly following the IVF injection, but there was no significant change in BCVA or CST. Mean (± standard deviation) BCVA changed from 0.34 ± 0.37 to 0.36 ± 0.40 (P = 0.29), CST changed from 242 ± 72 to 242 ± 82 µm (P = 0.99), and CCT changed from 189 ± 98 to 179 ± 97 µm (P < 0.0001). When the changes were evaluated according to the previous anti-VEGF agent administered, CCT was found to be significantly decreased by 8.7 ± 2.5 µm (P < 0.0001) in eyes previously treated with brolucizumab and by 13.1 ± 3.6 µm (P < 0.0001) in eyes previously treated with aflibercept. No adverse events were observed during the study period.
Conclusion: Intravitreal faricimab injection is a safe and effective treatment for nAMD in terms of short-term outcomes. Further long-term study is necessary.
