Real-world big data demonstrates prevalence trends and developmental patterns of myopia in China: a retrospective, multicenter study.

ABSTRACT:

Background

Myopia is a complex disease caused by a combination of multiple pathogenic factors. Prevalence trends and developmental patterns of myopia exhibit substantial variability that cannot be clearly assessed using limited sample sizes. This study aims to determine the myopia prevalence over the past 60 years and trace the myopia development in a school-aged population using medical big data.

Methods
