A representative case of polypoidal choroidal vasculopathy with cluster polypoidal lesions in retro-mode imaging.

<p>(Left column) From top to bottom are the fundus photograph, FFA and the early and late phase of ICGA. The fundus photograph shows reddish-orange lesions with a serosanguineous retinal pigment epithelium detachment in the macular area. The FFA shows occult CNV and a subretinal hemorrhage. The early phase of the ICGA shows polypoidal lesions with branching choroidal vascular networks and oval PED. The late phase of the ICGA shows the “washout” of the polypoidal lesions and leakage from branching choroidal vascular networks (arrow) and serosanguineous retinal pigment epithelium detachment (Right column, top). Retro-mode imaging using the right-deviated aperture shows well-defined cluster polypoidal lesions and serosanguineous retinal pigment epithelium detachment with a convex appearance (Right column, middle). Retro-mode imaging using the left-deviated aperture shows a well-defined cluster polypoidal lesions and serosanguineous retinal pigment epithelium detachment with a concave appearance (Right column, bottom). Both vertical and horizontal cross-sectional OCT scans show a large, steep, hemorrhagic PED. The vertical cross-sectional OCT scan shows an irregular RPE (arrow) above the hemorrhagic PED.
