Alterations in Peripheral Refraction are Most Significant Just Before the Onset of Myopia: Evidence from Multispectral Refraction Topography.

ABSTRACT:

Introduction

This study aims to explore the characteristics of retinal defocus values (RDVs) during refractive development of Chinese children.

Methods

In this cross-sectional study, 2125 children (2125 right eyes) aged 4-15 years were included and divided into several groups according to spherical equivalent (SE) or axial length (AL). Ocular biological parameters including AL, central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT) and corneal curvature were detected, and multispectral refractive tomography (MRT) was used to measure total retinal defocus values (TRDV), RDVs of 0°-15°/15°-30°/30°-45° concentric annulus area (RDV-15/30/45), RDVs of the superior, nasal, inferior and temporal fan-shaped region (RDV-S/N/I/T).

Results
