Abstract
Introduction: Anti-vascular endothelial growth factor (VEGF) treatment stands as the primary approach for neovascular age-related macular degeneration (nAMD). Faricimab has recently emerged as a novel anti-VEGF option for nAMD. This study aimed to assess the efficacy of faricimab in patients with refractory nAMD. Method: This retrospective study focused on refractory nAMD patients treated with faricimab at Taipei Veterans General Hospital from March 2023 to December 2023. Primary outcomes assessed the change in mean best-corrected visual acuity (BCVA) and central retinal thickness (CRT) over the first 4 months. Secondary outcomes included the presence of subretinal and intraretinal fluid (SRF and IRF) and changes in pigment epithelial detachment (PED). Subgroup analysis for the successful and unsuccessful treatment groups was conducted to identify potential confounding factors influencing treatment response. Result: This study included 42 eyes with refractory nAMD treated with faricimab. During a 6-month follow-up, no significant improvement in BCVA was observed, while CRT significantly decreased at all time points, except during the 5-month follow-up. Height PED showed significant reduction up to 5 months. The prevalence of SRF decreased significantly, while IRF remained lower but not significant. According to the treatment criteria, 67.4% successfully met the treatment goals. Subgroup analysis between successful and unsuccessful groups showed no significant differences in baseline characteristics, except a higher predominantly serous PED percentage in the successful group. Conclusion: Faricimab showed favorable outcomes in refractory nAMD patients. Further investigations are needed to understand the factors contributing to its efficacy.
