Characteristics of vortex vein in healthy eyes and fundus diseases imaged by ultra-widefield OCTA.

ABSTRACT:

Purpose

To investigate the characteristics of the vortex vein (VV) in healthy adults and patients with different fundus diseases using montaged ultra-widefield swept-source optical coherence tomography angiography (UWF SS-OCTA) images.

Methods

En face UWF SS-OCTA mosaic choroidal images in five fixation directions and macular scan were acquired in healthy adults, patients with normal choroidal thickness (retinal vein occlusion, diabetic retinopathy), patients with thick choroidal thickness (central serous chorioretinopathy and polypoidal choroidal vasculopathy), and patients with thin choroidal thickness (retinitis pigmentosa, and high myopia). The frequency, morphology, anastomoses, asymmetry and vascularity index (CVI) of VVs were assessed.

Results

The totality of V
