Purpose.
To investigate the refraction and ocular biometry characteristics and to examine the prevalence of refractive errors in preschool children aged 3 to 6 years in Shanghai, China.
Methods.
A school-based cross-sectional study was conducted in Jiading and Xuhui District, Shanghai, in 2013.
We randomly selected 7 kindergartens in Jiading District and 10 kindergartens in Xuhui District, with a probability proportionate to size.
The children underwent comprehensive eye examinations, including cycloplegic refraction and biometric measurements.
Myopia, hyperopia, astigmatism were defined as spherical equivalent (SE) ≤ −0.50 D, SE ≥ +2.00 D, and cylindrical diopters ≤ −1.00 D.
Results.
The mean SE for 3- to 6-year-old children was +1.20 D (standard deviation [SD] 1.05), and the mean axial length (AL) was 22.29 mm (SD 0.73).
The overall prevalence of myopia and astigmatism was 3.7% and 18.3%, respectively.
No difference in prevalence of astigmatism was found across age groups.
There was a statistically significant association between lower cylindrical diopters and higher spherical diopters (Spearman’s correlation: −0.21, P<0.001).
Conclusion.
Chinese children aged 3 to 6 years in the Shanghai area were mostly mildly hyperopic, with a low prevalence of myopia.
Refractive astigmatism for children may be relatively stable throughout the preschool stage.
Astigmatism was significantly associated with refractive error.
