Biometric Determinants of Epithelial Thickness Profile Across a Wide Range of Refractive Errors.

ABSTRACT:

Introduction

To evaluate the corneal epithelial thickness (CET) profiles and their correlations with axial length (AL) and anterior corneal radius of curvature (Rm F) across different refractive error groups.

Methods

A total of 1225 eyes of 616 normal patients were included. CET mapping, AL, and Rm F were obtained using spectral-domain optical coherence tomography, optical biometry, and Scheimpflug corneal tomography, respectively. In the CET map, one central (2 mm), eight paracentral (2-5 mm), and eight peripheral (5-6 mm) quadrants were evaluated separately. The subjects were divided into four groups based on their refractive status: hyperopia (spherical equivalent [SE] ≥  +0.50 D), emmetropia (SE >  -0.50 D and <  +0.50 D), low myopia (SE ≤ -0.50 D and >  -3.0 D), and mod
