Choroidal Thickness and Its Association With Age, Axial Length, and Refractive Error in Chinese Adults.

ABSTRACT:

Purpose

To identify the association between the choroidal thickness (ChT) with age and axial length (AL) under different refractive errors (REs) in Chinese adults.

Methods

Swept-source optical coherence tomography was used to measure ChT in 2126 right eyes of 2126 participants. The participants were classified as having pathologic myopia (PM), high myopia without PM (HM), low myopia (LM), and nonmyopia (non-M) according to their REs and META-PM (the Meta-Analysis of Pathologic Myopia) classification criteria.

Results

The mean age was 52.49 ± 20.39 years (range, 18-93 years), and the mean RE was -5.27 ± 5.37 diopters (D; range, -25.5 to +7.75 D). The mean average ChT was 159.25 ± 80.75 µm and decreased in a linear relationship from non-M to PM (190.04 ± 72.64 µm to 60.
