Profiles of Choroidal Vortex Vein Drainage System Using Ultra-Widefield OCT Angiography in a Chinese Population.

ABSTRACT:

Purpose

To develop a normative profile for choroidal vortex vein systems based on ultra-widefield OCT angiography (UWF-OCTA) in a healthy Chinese population.

Design

A cross-sectional, multicenter study.

Participants

A total of 515 eyes of 515 Chinese adults (515 healthy eyes) aged ≥20 years were recruited from the Choroidal Vortex Vein System Study.

Methods

All participants underwent comprehensive ophthalmic examinations. The 2-dimensional and 3-dimensional choroidal parameters of the vortex vein system were measured in each vortex vein drainage quadrant (24 × 20 mm² scan mode; central, superotemporal [ST], superonasal [SN], inferonasal [IN], and inferotemporal [IT] quadrants) using a UWF-OCTA device. The normative profile examined the choroidal para
