Abstract Purpose:To assess the 12-month(12M)treatment outcomes of patients with neovascular age-related macular degeneration(nAMD)who switched to intravitreal injections of ranibizumab biosimilars(IVRBS)during the maintenance phase.

Subjects and Methods:Twenty-four eyes of 22 patients with nAMD whose treatment protocol was switched from intravitreal injections of aflibercept(IVA)or ranibizumab(IVR)to IVRBS using a treat-and-extend(TAE)regimen at Chiba University Hospital between December 2022 and April 2023 were included in this retrospective study. The best-corrected visual acuity(BCVA), number of injections, treatment intervals, and dry macula rate were recorded during the 12M follow-up period. Optical coherence tomography was performed to measure the central foveal thickness(CFT)and central choroidal thickness(CCT).

Results:The mean age at the time of switching(baseline;BL)was 77.4 years. The nAMD subtypes were as follows:type 1 MNV, three eyes;type 2, five eyes;type 3, four eyes;and polypoidal choroidal vasculopathy, 12 eyes. The BCVA(logMAR)at BL, 6 months(6M), and 12M was 0.33±0.44, 0.37±0.49, and 0.31±0.40, respectively, indicating no significant differences. The CRT(μm)at BL, 6M, and 12M was 209±65, 232±118, and 203±78, respectively, indicating no significant differences. The mean treatment interval and number of injections at 12M were 11.5±3.0 weeks and 5.4±0.8, respectively. Dry maculae were observed in 17 eyes(71%). Eight eyes(33%)were switched to alternative agents within 12 months owing to worsening exudative changes.

Conclusions:Switching to IVRBS facilitated the maintenance of visual acuity and retinal thickness over 12 months.
