Year: 2024

Abstract: INTRODUCTION: The aim of this study was to investigate the predictive factors for persistent disease activity following anti-vascular endothelial growth factors (anti-VEGF) and their long-term effects in patients to be treated for neovascular age-related macular degeneration (nAMD) under real-world conditions. METHODS: Retrospective data analysis of the PROOF study, a multi-center real-world retrospective chart review conducted across Korea in patients with nAMD included treatment-naive patients with nAMD who received first anti-VEGF (ranibizumab, bevacizumab, or aflibercept) between January 2017 and March 2019 was performed. All 600 patients (cohort 1) had a minimum follow-up of 12 months of which 453 patients (cohort 2) were followed-up for 24 months from baseline. RESULTS: At month 12 after anti-VEGF therapy, 58.10% (95% confidence interval [CI]: 54.09, 62.12) of patients and at month 24, 66.02% of patients continued to have persistent retinal fluid. At both months 12 and 24, predictive factors for persistent disease activity were fibrovascular pigment epithelial detachments (PED) (P = 0.0494) and retinal fluid at month 3 after loading phase (P = 0.0082). The mean changes in visual acuity were + 6.2, + 10.1, and + 13.3 letters and in the central subfield thickness were - 79.1 µm, - 96.3 µm, and - 134.4 µm at 12 months from baseline, in the bevacizumab, aflibercept, and ranibizumab groups, respectively. CONCLUSIONS: The presence of retinal fluid after loading phase and fibrovascular PED were predictors of persistent disease activity after at least 1 year of anti-VEGF treatment.
