Optical Coherence Tomographie Findings of Idiopathic Polypoidal Choroidal Vasculopathy

* BACKGROUND AND OBJECTIVE: To identify the histological level of abnormal vessels associated with idiopathic polypoídal 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 Bruchs membrane and RPE. We consider that this disease is a peculiar form of age-related macular degeneration. [Ophthalmic Surg Lasers 2000;31:210-214]
