摘要

Purpose

While it is known that anti-vascular endothelial growth factor (anti-VEGF) treatment for neovascular age-related macular degeneration (nAMD) leads to a reduction in choroidal thickness in the macula, changes in peripheral choroidal thickness remain unclear. This study aimed to evaluate choroidal thickness changes following three monthly intravitreal injections of aflibercept and faricimab in treatment-naïve nAMD.

Methods

Treatment-naïve nAMD patients receiving three consecutive monthly injections as the loading phase were enrolled in this study. Wide-field swept-source OCT was used to quantify regional choroidal thickness. In the 1:1 propensity score matching, sex, age, baseline best-corrected visual acuity, axial length, and nAMD subtypes were selected as covariates.

Results

A total of 142 eyes from 142 patients were included, with 71 eyes receiving aflibercept and 71 eyes receiving faricimab. Significant reductions in choroidal thickness were observed in both central and peripheral areas, with the most pronounced changes occurring in the central 3 mm–subfield. After propensity score matching, choroidal thickness change rates were compared between the two drug groups. In the central 3 mm–subfield, aflibercept was associated with a significantly greater reduction in choroidal thickness compared with faricimab. No significant differences were observed in other subfields.

Conclusion

This study highlights the importance of considering both central and peripheral choroidal changes when evaluating the impact of different anti-VEGF therapies in nAMD.
