Abstract

This study evaluated the predictive efficiency of non-cycloplegic ocular parameters for premyopia and myopia in children. Data from 493 patients aged 3-17 were retrospectively analyzed. AL/ACRC demonstrated the strongest predictive performance for premyopia and myopia, with an area under the receiver operating characteristic curve (ROC) of 0.956 (95% CI: 0.934-0.973). A combined predictor using NCSER≤0 and AL/ACRC > 2.95 achieved a higher Youden index than AL/ACRC alone (0.85 vs. 0.813). In the absence of cycloplegic refraction, AL/ACRC alone or in combination with NCSER may serve as effective alternative predictors for premyopia and myopia.
