Polypoidal choroidal vasculopathy. a. A patient with faint orange subretinal lobular structures temporal to the fovea in the right eye. b. The patient presented with subretinal hemorrhage from an isolated polyp in the left eye. c. Optical coherence tomography (OCT) of the right eye showed an extensive low-lying pigment epithelial defect. d. OCT of the left eye showed the double-layer sign associated with polypoidal choroidal vasculopathy (arrow indicates subretinal pigment epithelium linear hyperreflectivity) in addition to extensive subretinal fluid. e. Indocyanine green angiography demonstrated the presence of a branching network of vessels in the right eye.
