Preferential Locations of Polypoidal Lesions and Adjacent Pigment Epithelium Detachments in Polypoidal Choroidal Vasculopathy in a Japanese Population.

ABSTRACT:

Purpose

To analyze the relationship between neovascular lesions in polypoidal choroidal vasculopathy (PCV) and vortex vein characteristics.

Methods

Eighty eyes from 77 patients with PCV were examined using widefield swept-source optical coherence tomography (OCT) and indocyanine green angiography. Polypoidal lesions and pigment epithelial detachments (PEDs) were mapped onto choroidal en face OCT images. Vortex vein drainage areas were assessed for vertical asymmetry, and their associations with lesion locations were analyzed. Choroidal thickness was measured centrally and peripherally. Eyes were classified as pachychoroid or non-pachychoroid.

Results

Thirty-nine eyes (49%) and 41 eyes (51%) were included in the pachychoroid and non-pachychoroid groups, respectively. I
