Reference Values of Non-Cycloplegic Spherical Equivalent for Screening and Predicting Myopia Among Children and Adolescents - China, 2020-2024.

ABSTRACT:

Introduction

Non-cycloplegic refraction is widely utilized in vision screening. However, interpreting non-cycloplegic refraction results remains a significant challenge in both clinical practice and public health settings. This study aimed to establish grade- and sex-specific reference values for non-cycloplegic spherical equivalent (SE) to enhance myopia screening and risk prediction among Chinese students.

Methods

A comprehensive study was conducted between 2020 and 2024, involving 67,260 students from kindergarten through high school across 10 provincial-level administrative divisions (PLADs) in China. The Lambda-Mu-Sigma method was employed to model non-cycloplegic SE. Reference values were established by calculating SE centiles corresponding to myopia and high myopia pr
