Brolucizumab intravitreal injection in macular neovascularization type 1: VA, SD-OCT and OCTA parameters changes during a 16-weeks follow up

Abstract

Purpose: to assess the anatomical and functional changes after brolucizumab intravitreal injection (BIVI) in macular neovascularization type 1 (MNV1). Setting/Venue: Ophthalmology Clinic, University "G. d'Annunzio" of Chieti-Pescara. Methods: A total of 24 eyes of 24 patients suffering from naïve MNV1 candidates to BIVI as per label with q12/q8 dosing regimen after the loading dose were enrolled in this prospective study. Main outcome measures during a 16-weeks follow up period included changes of best corrected visual acuity (BCVA), central macular thickness (CMT), subfoveal subretinal fluid thickness (SSRFT), subfoveal sub-RPE fluid thickness (SSRPEFT), subfoveal choroidal thickness (SFCT) and pigment epithelial detachment (PED) maximum height (PED-MH). In addition, percentages of eyes with intraretinal fluid, subretinal fluid and sub-RPE fluid at different time points and percentages of eyes candidates to a q8 or q 12 injection interval after disease activity assessment at week 16 were evaluated. Results: BCVA improved significantly from baseline (T0) to week 12 (T3) (p=0.028). CMT showed a significant reduction from 456.0±123.0 µm at T0 to 265.0±85.0 µm at T3 (p
