Structure of Polypoidal Choroidal Vasculopathy Studied by Colocalization Between Tomographic and Angiographic Lesions

Late geographic hyperfluorescence on ICGA corresponds with the double-layer sign on OCT in eyes with PCV. Our observations suggest that the double-layer sign consists mainly of fibrous tissue harbored by the branching vascular network, and late geographic hyperfluorescence may originate from the staining of tissue.
