Polypoidal choroidal vasculopathy coexisting with exudative age-related macular degeneration

Abstract

To report two cases that had polypoidal choroidal vasculopathy (PCV) coexisting with choroidal neovascularization (CNV) of exudative age-related macular degeneration (AMD). Both of the patients underwent color photographs, fluorescein and indocyanine green (ICG) angiography. On fundus examination, a grayish lesion in the foveal area, reddish-orange lesions and hemorrhagic retinal pigment epithelial detachments (PED) in the inferotemporal vascular arch were disclosed in the left eye of a patient, and macular scarring was observed in the fellow eye. ICG angiography revealed a typical branching vascular network and polyp-like aneurysmal dilations at terminals of branches in the inferotemporal vascular arcade and a well-demarcated hyperfluorescent area of CNV in the fovea in the left eye, and staining of macular scarring was present in the fellow eye. On fundus examination of the right eye of the other patient a gray-yellow lesion at the fovea, reddish-orange lesions in the extramacula were noted, and diffuse drusens were present in the fellow eye. ICG angiography revealed scattered polyp-like aneurysmal dilations without identifiable continuous branching vascular network in the extramacula, and a well-demarcated hyperfluorescence area of CNV in the fovea. PCV can coexist with exudative AMD in some patients and the polypoidal lesions may less involve in the fovea than CNV. Evidence of AMD are present meanwhile in the fellow eyes these patients.
