Abstract

PURPOSE:

To document and study the cross-sectional structures of polypoidal elements using optical coherence tomography in eyes with idiopathic polypoidal choroidal vasculopathy.

METHODS:

Optical coherence tomography images of two eyes with idiopathic polypoidal choroidal vasculopathy were correlated with slit-lamp biomicroscopic findings, fundus photographs, fluorescein angiograms, and indocyanine green angiograms.

RESULTS:

Cross-sectional optical coherence tomographic images of retinochoroidal structures showed prominent anterior protrusion of the orange subretinal mass corresponding to the polypoidal structure in the indocyanine green angiogram. Hemorrhagic detachment of the retinal pigment epithelium was contiguous with the cone-shaped nodule beneath the retinal pigment epithelium in one eye, and an apparent discontinuity was observed in the highly reflective layer that delineates the polypoidal structure.

CONCLUSIONS:

Some of the polypoidal structures in eyes with idiopathic polypoidal choroidal vasculopathy are anteriorly protruding lesions in the inner choroid that may cause serosanguineous detachment of the retinal pigment epithelium through damage of the overlying Bruch membrane, retinal pigment epithelium, and the adhesion between them. Cross-sectional optical coherence tomographic images may increase understanding of the pathophysiology of idiopathic polypoidal choroidal vasculopathy.
