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-naïve 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 = 0.47–1 logMAR) and improved to 0.3 logMAR (IQR = 0.25–0.6 logMAR), whereas the mean macular thickness improved from 443 ± 60 mm at baseline to 289 ± 25 mm (P < 0.001) at the last follow-up period. None of the eyes experienced any intraocular inflammation across 48 injection sessionsConclusion:Brolucizumab is safe and effective in controlling PCV disease in both treatment-resistant and treatment-naïve eyes.
