Purpose. To investigate the incidence and timing of prechoroidal cleft development and its association with visual prognosis in\ntype 3 neovascularization. Methods. This retrospective study included 166 eyes that were diagnosed with type 3 neovascularization.\nAll eyes were treated with antivascular endothelial growth factor therapy. The incidence and timing of prechoroidal cleft development\nwere evaluated. Best-corrected visual acuity (BCVA) at diagnosis and at final follow-up was compared between eyes\nwith (cleft group) and without (no-cleft group) prechoroidal cleft. The incidence of retinal pigment epithelium (RPE) tear and\nsubretinal hemorrhage was also compared between the two groups.
