Polypoidal Choroidal Vasculopathy Imaging by Indocyanine Green Angiography and En Face Optical Coherence Tomography
This case report describes polypoidal choroidal vasculopathy imaged by indocyanine green angiography and en face optical coherence tomography. Polypoidal choroidal vasculopathy is a variant of subretinal neovascularization. It causes subretinal exudation, subretinal hemorrhage, and retinal pigment epithelial (RPE) detachments. Indocyanine green angiography can visualize well the characteristic branching vascular network and polypoidal dilations lying beneath the RPE. En face optical coherence tomography using data from noninvasive spectral-domain optical coherence tomographic imaging may localize polypoidal choroidal vasculopathy vessels beneath the RPE by using en face imaging software, creating a 20- to 30-μm slice beneath the RPE.
