Influence of dynamic changes of ocular biometric parameters on new-onset myopia in Chinese children: a 4-year cohort study.

ABSTRACT: To analyze the incidence and progression rates of myopia among children aged 6-8 years in Chengdu, and to evaluate the influence of baseline parameters and dynamic changes in ocular biometric parameters on new-onset myopia risk. A total of 26,169 students aged 6-8 years from eight administrative districts in Chengdu were followed annually for 4 years. All students underwent uncorrected distance visual acuity testing, non-cycloplegic autorefraction, and ocular biometric parameters. Potential risk factors for myopia onset were screened through multivariate logistic regression analysis. The influence of each factor was evaluated using the area under the curve (AUC). Results showed that the baseline prevalence of myopia was 17.8%. The cumulative incidence rates of myopia were 8.1-13.4% (2nd ye
