The main outcome measures included best-corrected visual acuity (BCVA), central macular thickness (CMT), central choroidal thickness (CCT), number of IVA injections, and macular atrophy (MA). Polypoidal lesions before and after the loading phase were assessed using indocyanine green angiography.Results: In both groups, BCVA significantly improved after the loading phase and was maintained for 2 years. CMT and CCT were significantly reduced in both groups, without significant differences after 2 years between the groups (P=0.2708). The mean number of IVA injections in the IVA and PDT+IVA groups during the 2 years were 13.2± 3.3 and 12.7± 1.8, respectively, without a significant difference (P=0.06). The frequencies of MA expansion in the IVA and PDT+IVA groups during the 2 years were 25.9% and 33.4%, respectively, with no significant difference in the incidence (odds ratio: 1.40, P=0.4253). The ratios of polyp regression after the loading phase in the IVA and PDT+IVA groups were 55.2% and 94.1%, respectively, with a significant difference (P< 0.0001).Conclusion: PDT combined with IVA injections using a TAE regimen is effective for anatomical and visual function improvement, without a significant difference as compared to IVA monotherapy. It can facilitate complete regression of polyps with higher odds.Keywords: polypoidal choroidal vasculopathy, aflibercept, photodynamic therapy, treat-and-extend, macular atrophy
