Abstract: Objective To investigate the current situation of 0 to 6 years old children's refraction,and provide information for detecting refrangibility. Methods A total of 17 356 children aged from 0 to 6 years old were examined with Suresight hand-held refractometer.The data were ananlysed statistically. Results Compound hypermetropia astigmatism and simple hypermetropia were predominant in the reflection types in 0~6 years old children.Hypermetropia and compound hypermetropia astigmatism decreased with the age increase(P<0.01).Emmetropia,myopia,simple myopia increased with the age increase(P<0.01).The spherical diaopter and the cylinder diopter decreased with the age increase.The reference ranges of all aged groups were gained. Conclusions It is necessary to check the 0~6 years old children's refraction.Much attention should be paid attention to detecting refrangibility and the age factor to prevent overdiagnosis.

摘要： 目的 了解0～6岁儿童的屈光发育现状,为儿童屈光筛查工作提供依据。 方法 应用美国伟伦Suresight手持自动验光仪对17 356名0～6岁儿童进行屈光检查,并将结果进行统计学分析。结果 0~6岁儿童的屈光类型主要为复性远视散光和单纯远视。远视、复性远视散光随年龄增长逐渐减少(P<0.01),正视、近视、单纯近视随年龄增长逐渐增多(P<0.01)。各年龄组球镜、柱镜均数随着儿童年龄增长其屈光值逐渐减低。统计得出各年龄组球柱镜的参考值范围。 结论了解0~6岁各年龄的屈光状况非常必要。要重视儿童屈光筛查工作并要结合年龄发育因素,防止诊治扩大化。
