Popis:	Five eyes of five patients with polypoidal choroidal vasculopathy (PCV) without acute hemorrhagic changes or subretinal proliferative tissue to observe the three-dimensional structures and to demonstrate the nature of these images and their interpretation. The abnormal networks surrounding polypoidal lesions were considered to be abnormal pathological blood vessels. The segmentation analysis of spectral-domain optical coherence tomography (OCT) has revealed the three-dimensional features of polypoidal lesions and surrounding abnormal blood vessel networks beneath retinal pigment epithelium. The changes of pathological findings of PCV were also detected, including the enlargement of hemorrhagic pigment epithelium detachment (PED). The segmentation analysis is useful to observe PCV lesions from the bird's eye view.
