摘　　要：目的研究12岁以下年幼低常儿童眼散光的分布规律。主要类型及与弱视的关系。方法对门诊4~12岁视力低常儿童829例1349只眼散光进行统计分析。结果复性远视散光最多占57.60%,其他依次为复性近视散光30.62%,混合散光8.15%,单纯远视散光2.22%,单纯近视散光1.41%。散光程度以0.5DC^1.00DC为主,占56.12%,其次为1.25DC^2.00DC占25.72%,2.25DC^3.00D占10.16%,>3.00DC者占8.01%。顺规散光占94.81%,逆规散光占3.93%,斜向散光占1.26%。矫正视力≥0.9者占52.34%,矫正视力<0.9者占47.66%。结论复性远视散光是学龄前儿童散光的主要类型,散光与弱视的形成有关。应合理矫正儿童眼散光。Objective To investigate distribution rules, the main type of astigmatism and the relation and the corrected visual acuity in the children from four to twelve. Methods 829 cases 1349 eyes of astigmatism were statistically analyzed. Results In the astigmatic eyes, compound hyperopia astigmatism was the most（57.60% ）, then was compoundmyopia astigmatism （30.62%）, third was the mixed astigmatism （8.15 % ）, simple hyperopia astigmatism（ 2.22 % ）, the last was simplemyopia astigmatism （1.41% ）. In the constituent ratio of astigmatic diopter, 0.50DC to 1.00DC made up 56.12% of theastigmatic eyes, 1.25DC to 2.00DC 25.72% ,2.25DC to 3.00DC 10.16% ,and 〉 3.00DC 8.01%. Direct astigmatism made up 94.81% of the astigmatic eyes, indirect astigmatism 3.93%, and oblique astigmatism 1.26%. corrected visual acuity≥0.9 made up 52.34%, and 〈 0.9 made up 47.66%. Conclusion The main type of astigmatic with the preshool children age is compound hyperopia astigmatism. There is an association between astigmatic and amblyopia. The children with astigmatic must be corrected.
