Optical coherence tomography (OCT) in idiopathic polypoidal choroidal vasculopathy (IPCV)

Purpose: Idiopathic polypoidal choroidal vasculopathy (IPCV) is a distinct clinical entity characterized by an edematous maculopathy and typical choro idal vascular change. The purpose of this study is to evaluate the use of o ptical coherence tomography (OCT) for diagnosing of this disease. Methods: 4 patients affected by IPVC (mean age 71-84 years) underwent biomicroscopy with a three mirror conctact lens, fluorescein angiography (FA), indocyanin e green angiography (ICGA) and OCT (Humphrey Zeiss) scan. Results: in all 4 cases OCT tomograms acquired at the location of the typical choroidal abno rmalities demonstrated by ICGA, revealed a characteristic hyper-reflectivit y in the choroidal layers. Conclusion: ICGA is essential to diagnose IPVC, but OCT may be able to identify characteristic reflectivity patterns.
