Choroidal Circulation in 8- to 30-Year-Old Chinese, Measured by SS-OCT/OCTA: Relations to Age, Axial Length, and Choroidal Thickness.

ABSTRACT:

Purpose

The purpose of this study was to evaluate and explore the determinants of choroidal vascularity and choriocapillaris perfusion in a Chinese population aged 8 to 30 years old.

Methods

Three hundred eighty eyes from 380 subjects aged 8 to 30 years were included in this cross-sectional study. Submacular choroidal thickness (ChT), total choroidal area (TCA), luminal area (LA), stromal area (SA), choroidal vascularity index (CVI), and choriocapillaris flow deficit (CcFD) were estimated using images obtained from optical coherence tomography (OCT).

Results

In this population, the mean ChT was 260.4 ± 63.3 µm, TCA was 1.56 ± 0.38 mm2, LA was 0.94 ± 0.25 mm2, and SA was 0.62 ± 0.15 mm2. The mean CVI was 60.25 ± 3.21% and CcFD was 11.95 ± 1.98%. Multivariable analyses
