Purpose: To introduce novel findings of polypoidal choroidal vasculopathy (PCV) via optical coherence tomographyangiography (OCTA)Methods: This study is a retrospective chart review of 16 patients (16 eyes) with PCV. OCTA (Avanti RTVue XR)findings were evaluated and selected for analysis after agreement by two retina specialists . Results: Twenty one polyps in 16 eyes (16 patients) with PCV were included in this study. The mean patientage was 67 years (13 men and three women). The shape of polypoidal lesions on OCTA at initial were halo(five polyps), rosette (seven polyps), and vascular network (nine polyps). Eight months after anti-vascular endothelialgrowth factor treatment, in a total of four eyes, seven polyps could be followed up completely, thetwo halo type polypoidal lesions changed to rosette and vascular network type. The lesions of three rosetteand two vascular network type lesions did not change in shape. In addition, the size of the polypoidal lesions(one among two halo types, two among three rosette types, and two among two vascular network types) decreased,but one halo type did not change and one rosette type increased in size on OCTA. Conclusions: En-face OCTA enabled us to categorize novel types of PCV with polypoidal lesions.
