We evaluated visual acuity (VA), central subfield thickness (CST), macular volume (MV), pigment epithelial detachment (PED) height and choroidal thickness (CT) after one administration of faricimab. Where present, fluid was further evaluated according to intraretinal fluid (IRF), subretinal fluid (SRF) or within PED.Seventy-one eyes from 71 patients were included (45.07% PCV and 54.93% typical nAMD). Mean (standard deviation (± SD) VA, CST and MV improved from 0.50 (± 0.27) to 0.46 (± 0.27)logMAR, p=0.20, 383.35(± 111.24) to 322.46(± 103.89) µm, p<0.01,and 9.40(± 1.52) to 8.75(± 1.17)mm 3 , p<0.01 from switch to post switch visit. CT reduced from 167(± 151) to 149(± 113)µm, p<0.01. There was also significant reduction in maximum PED height between visits, 302.66(± 217.97)µm and post switch visit 236.66(± 189.05)µm, p<0.01. This difference was greater in PEDs that were predominately serous in nature.In eyes with typical nAMD (n=39), improvements were significant for CST, MV, CT and PED. In eyes with PCV (n=32), only reductions in CT were statistically significant, while VA, CST, MV and PED only showed numerically smaller improvements. One patient developed mild vitritis without vasculitis, which resolved with topical steroids with no sequelae.In our series of Asian nAMD, switching to Faricimab was associated with stable visual acuity and meaningful anatomical improvements, particularly with typical nAMD subtypes.
