Optical coherence tomographic findings of idiopathic polypoidal choroidal vasculopathy

Ophthalmic Surg Lasers. May-Jun 2000;31(3):210-4.

Abstract

Background and objective: To identify the histological level of abnormal vessels associated with idiopathic polypoidal choroidal vasculopathy (IPCV), we examined IPCV with Optical Coherence Tomography (OCT).

Patients and methods: Fourteen patients diagnosed with IPCV were examined with Indocyanine green (ICG) angiography and OCT.

Results: ICG angiography demonstrated branching vascular networks with polypoidal dilatations at the terminals beneath the retinal pigment epithelium (RPE). OCT showed dome-like elevation of the RPE, and moderate reflex or nodular appearance were seen beneath the RPE.

Conclusion: The abnormal vessel associated with IPCV is supposed to be choroidal neovascularization with polypoidal dilatations at the terminals between Bruch's membrane and RPE. We consider that this disease is a peculiar form of age-related macular degeneration.
