PURPOSE: To investigate baseline characteristics associated with the incidence of intraocular inflammation (IOI) after the intravitreal injection of brolucizumab (IVBr) for the treatment of neovascular age-related macular degeneration (nAMD).
METHODS: This retrospective study included 66 eyes of 62 consecutive patients with nAMD who received IVBr (18 eyes were treatment naïve and 48 eyes had switched from other anti-vascular endothelial growth factor [VEGF] therapy). Baseline clinical characteristics were compared in non-IOI and IOI groups.
RESULTS: Although a dry macula was achieved at a high rate even 6 months after IVBr, IOI occurred in 8 of 66 eyes (12.1%; all had switched therapy) during the study period. Baseline characteristics including age, sex, nAMD type, lens status, visual acuity, central macular thickness, and a history of diabetes did not differ between the groups. The number of previous anti-VEGF injections before IVBr was greater in the IOI group (P = 0.004), and the ratio of patients with a laser flare-cell photometry (LFCP) value over 15 photon count per millisecond (pc/ms) was higher in the IOI group (P = 0.017). Multivariate logistic regression analysis showed that a greater number of previous anti-VEGF injections (odds ratio [OR]: 1.12, P = 0.006; area under the curve: 0.82, cut-off score: 14.0) and an LFCP value over 15 pc/ms (OR: 81.6, P = 0.031) were significantly associated with the incidence of IOI after IVBr.
CONCLUSION: A number of previous anti-VEGF injections greater than 14 and an LFCP value more than 15 pc/ms might be useful predictors of the incidence of IOI after IVBr in eyes with nAMD.
