Prediction of myopia based on biometric parameters of 500,000 children and adolescents aged 3-18 years.

ABSTRACT:

Purpose

To explore the validity and significance of the axial length/corneal radius (AL/CR) Ratio for myopia prediction in children of all ages.

Methods

Between 2020 and 2022, 509,530 children and adolescents aged 3-18 years were sampled in Chengdu City, Sichuan Province, China, by whole-cluster sampling method. Measured their uncorrected visual acuity (UCVA), non-cycloplegic autorefraction, axial length (AL), and corneal radius (CR), Pearson's correlation coefficient and Receiver operating characteristic (ROC) curve were used to determine the accuracy and calculate the cutoff for myopia detection.

Results

The correlation between AL/CR ratio and SE was higher than that between AL and SE at different ages and refractive states. The area under the ROC curve (AUC) of myo
