Methods Mydriasis optometry was performed for preschool children in our hospital outpatient reception from 2010 to 2011,and the astigmatism in 831 eyes of 477 cases were statistically analyzed. Results The compound hyperopic astigmatism was the most, accounting for 65.8%,followed by mixed astigmatism (13.8%),simple hyperopia astigmatism (9%),compound myopia astigmatism (8.7%) and simple myopia astigmatism (2.3%). Preschool children astigmatism degree distribution was distributed among 0.50 D and 2.00 D, accounting for 42%. For astigmatism axial, the astigmatism with rule, astigmatism against the rule and oblique astigmatism was accounted for 95.9%, 2.4% and 1.7%, respectively.
