Abstract Introduction Intraocular inflammation (IOI)-related adverse events (AEs) that may result in severe vision loss have been associated with the anti-vascular endothelial growth factor brolucizumab. In this study, we investigate the timing, management and resolution of IOI-related AEs in a large cohort of patients treated with at least one injection of brolucizumab in routine clinical practice. Methods Retrospective review of medical records from patients with neovascular age-related macular degeneration treated with ≥ 1 brolucizumab injection between October 2019 and November 2021 at the Retina Associates of Cleveland, Inc. clinics. Results Of the 482 eyes included in the study, IOI-related AEs occurred in 22 (4.6%) eyes. Four (0.8%) eyes developed retinal vasculitis (RV) and of these, 2 (0.4%) had concomitant retinal vascular occlusion (RO). Most eyes [14/22 (64%)] developed the AE within 3 months and 4/22 (18%) within 3–6 months of the first brolucizumab injection. The median [interquartile range (IQR)] time from the last brolucizumab injection to development of the IOI-related AE was 13 (4–34) days. At the time of event, 3 (0.6%) eyes with IOI (no RV/RO) developed severe vision loss of ≥ 30 ETDRS letters, and a further 5 (1.0%) eyes (1 with IOI + RV, 1 with IOI + RV + RO) developed moderate vision loss of ≥ 15 letters compared with their last visual acuity (VA) prior to the AE. The median (IQR) vision loss was −6.8 (−19.9, –0.0) letters. Taking the best VA at either 3 or 6 months after AE resolution (or stability for occlusive events), VA decreased by ≥ 5 letters compared with prior to the AE in 3 (14%) of the 22 affected eyes, and was preserved (< 5-letter loss) in 18 (82%) eyes. Conclusions In this real-world study, most IOI-related AEs occurred early after brolucizumab treatment initiation. With appropriate monitoring and management of IOI-related AEs, vision loss associated with brolucizumab may be limited.
