Prevalence and risk factors of pseudomyopia in a Chinese children population: the Anyang Childhood Eye Study

British Journal of Ophthalmology Sep 02, 2020

Kang MT, Jan C, Li SM, et al. - Researchers conducted this prospective, school-based, cohort study to examine the prevalence and predictors of pseudomyopia, defined as spherical equivalent refractive (SER) error in the better–seeing eye ≤−0.50 D before cycloplegia and >−0.50 D after cycloplegia, in Chinese children and its correlation with myopia progression. This investigation was carried out in Anyang, China. In total, 2,612 children aged 6 years and 1,984 children aged 13 years were involved. Of the two cohorts, median cycloplegic SER (IQR) was 1.00 D and −1.13 D respectively, myopia prevalence was 5.2% and 61.0%, pseudomyopia prevalence was 24.1% and 18.9%, and median pseudomyopic power was 1.13 D and 0.38 D. The prevalence of pseudomyopia in younger, hyperopic children is greater. Pseudomyopia in this setting is not an independent risk factor for myopic progression.
