Abstract Purpose:To investigate the 1 year outcomes of switching to brolucizumab in neovascular age-related macular degeneration(nAMD)refractory to aflibercept.

Methods:This retrospective study was performed between July 2020 and June 2022 at Kawasaki Medical School Hospital. NAMD patients with persistent fluid after monthly intravitreal aflibercept injections switched to brolucizumab. We evaluated the best-corrected visual acuity(BCVA), central retinal thickness(CRT), total number of injections, and administration interval in all eyes.

Results:We evaluated BCVA, CRT, total number of injections, and administration interval in 11 eyes of 11 patients. One eye developed brolucizumab-related intraocular inflammation after the first injection. The mean BCVA and CRT were 0.34±0.26 and 266.8±39.3 μm at baseline, 0.33±0.29 and 220.8±55.8 μm at 4 months, 0.25±0.33 and 224.9±61.1 μm at 8 months, and 0.22±0.31 and 224.9±61.1 μm at 12 months. The mean BCVA did not changed significantly, but CRT decreased significantly at all time points(4, 8, and 12 months, p=0.03, p=0.03, and p=0.04, respectively). Of the ten eyes refractory to monthly aflibercept injections, six(60.0%)achieved a dry macula. The total number of injections was 6.9±0.3 for 1 year, and the administration interval was 8.6±1.3 weeks at 12 months.

Conclusion:Switching to brolucizumab in patients with nAMD refractory to aflibercept showed favorable outcomes in controlling intraocular fluid.
