摘要

Purpose

To investigate the clinical features and biomarkers associated with intraocular inflammation (IOI) following brolucizumab treatment in Asian switched neovascular age-related macular degeneration (nAMD) patients.

Study design

Multi-center, retrospective cohort study.

Methods

This study included 109 eyes from 93 nAMD patients switched from other anti-vascular endothelial growth factor (VEGF) agents to brolucizumab (Beovu) without loading. Baseline characteristics, IOI timing, initial symptoms, and risk factors were assessed.

Results

IOI was observed in 17 eyes from 14 patients, including anterior uveitis (AU, n = 7), intermediate uveitis (IU, n = 5), and panuveitis with or without retinal vasculitis (RV, n = 5). Two eyes were asymptomatic. The median duration for IOI onset was 26 days, with 11 of 17 eyes (82.4%) developing IOI before the third brolucizumab injection. Firth-penalized multivariate Cox regression analysis depicted that the total number of anti-VEGF injections within one year prior to brolucizumab initiation (HR = 1.4, p = 0.009) and retinal angiomatous proliferation (RAP) (HR = 10.9, p = 0.009), may be associated with IOI development. In contrast, baseline macular neovascularization (MNV) size and the presence of retinal pigment epithelial and outer retinal atrophy were not associated with IOI occurrence.

Conclusion

Vigilant examination after the initial brolucizumab injections is critical. Patients with identified risk factors may need meticulous monitor following brolucizumab injections.
