Brolucizumab in Pretreated Neovascular Age-Related Macular Degeneration: Case Series, Systematic Review, and Meta-Analysis

Blog Article

Background: Recalcitrant neovascular age-related macular degeneration (rnAMD) despite intensive intravitreal anti-neovascular endothelial growth factor (VEGF) treatment, can be handled by switching to another anti-VEGF agent.This first systematic review and meta-analysis presents long-term data after switching from another anti-VEGF agent to brolucizumab.Methods: Retrospective case series over two years of patients switched to brolucizumab, and a systematic review and meta-analysis of peer-reviewed studies presenting patients switched to brolucizumab.Weighted mean differences based on the random-effects models were calculated for Spoons best-corrected visual acuity (BCVA) and central subfield thickness (CST).Results: The systematic review draws on 1200 eyes switched to brolucizumab.

The meta-analysis showed a clinically irrelevant decrease in BCVA after one and two months, together with significant decreases in CST for up to one year after the switch but lacking power over 2 years.Of Pitchers twelve eyes (twelve patients) in our case series, five continued treatment for two years without experiencing significant changes.Conclusions: After switch to brolucizumab, a significant morphological improvement with CST reduction was shown in eyes with rnAMD.The small worsening of BCVA may be owing to the chronically active nature of rnAMD.Brolucizumab thus remains a treatment option in rnAMD despite its potential side effects.
