Initial experience in treating polypoidal choroidal vasculopathy with brolucizumab in Indian eyes � A multicenter retrospective study

ABSTRACT

Purpose: To report the initial experience of managing treatment?resistant and treatment?na飗e eyes with polypoidal choroidal vasculopathy (PCV) by using brolucizumab 6 mg. Methods: This was a retrospective multicentric series of all consecutive eyes with PCV treated with brolucizumab. Treatment resistance was defined as taking at least six prior anti?VEGF injections over the past 1 year and showing persistent disease activity in the form of intra (IRF) or subretinal fluid (SRF) or both. All patients were treated on a pro re nata (PRN) basis and followed up monthly. Retreatment was considered when either SRF or IRF were present at any time point during the study. Results: We included 21 eyes of 21 patients with PCV with a mean age of 65.1 � 9.9 years, of which 16 eyes (76%) were treatment?resistant. The mean follow?up period from receiving the first brolucizumab was 27.3 � 3.3 weeks. Of the 21 eyes, seven eyes (33%) received three injections during follow?up, 13 eyes (62%) received two injections, and one eye received one injection. The mean injection?free interval was 12 � 1.2 weeks. The median pretreatment vision was 0.6 logMAR (IQR = 0.47�logMAR) and improved to 0.3 logMAR (IQR = 0.25�6 logMAR), whereas the mean macular thickness improved from 443 � 60 ?m at baseline to 289 � 25 ?m (P < 0.001) at the last follow?up period. None of the eyes experienced any intraocular inflammation across 48 injection sessions. Conclusion: Brolucizumab is safe and effective in controlling PCV disease in both treatment?resistant and treatment?na飗e eyes
