Treatment outcomes of patients with neovascular age-related macular degeneration after switching from aflibercept to faricimab
摘要
Neovascular age-related macular degeneration (nAMD) can cause vision loss and irreversible blindness. However, its treatment needs to be improved. This study aimed to evaluate the 1-year treatment outcomes in patients with nAMD after switching from 2 mg aflibercept to faricimab.
Study designRetrospective observational study.
MethodsWe included 83 eyes of 83 patients with nAMD who switched from 2 mg aflibercept to faricimab to extend the administration interval or eliminate exudative changes, with ≥ 1 year of follow-up. We retrospectively examined the 1-year treatment outcomes after switching, with the time of switching as the baseline.
ResultsAfter switching, the mean log minimum angle of resolution best corrected visual acuity was significantly improved from 0.35 to 0.33 (p = 0.0498), and the mean central retinal thickness was significantly reduced from 302 μm to 237 μm (p < 0.0001). A significant reduction was observed in the incidence of subretinal fluid, intraretinal fluid, and subretinal pigment epithelial fluid (p < 0.05). The mean dosing interval was significantly extended from 5.58 weeks to 9.69 weeks (p < 0.0001). One year after switching, 66 eyes (80%) continued receiving faricimab, while 17 eyes (20%) were switched to other drugs owing to worsening exudation or other reasons.
ConclusionOne year after switching treatment for nAMD from 2 mg aflibercept to faricimab, visual acuity and macular morphology were improved, and the treatment interval was extended. The study’s findings could help develop strategies for improving nAMD.
