Abstract: : Objectives To analyze the outcome of Welch Allyn spot VS100 in testing for children aged 6 months to 6 years,and to determine the cut-off point of each age group. Methods Totally 15 342 children aged 6 months to 6 years were enrolled in this study from March to September in 2018 and conducted refractive screening by Spot VS100.Statistical descriptions and analysis were conducted by age to determine the cut-off points for each group. Results The x-±2s of spherical equivalent and P95 of cylinder in 6 to 12-month-old children,1 to 3-year-old children and 3 to 6-year-old children were -1.50 D —+2.00 D,2.75 D;-1.25 D —+1.75 D,2.00 D;and -0.75 D —+1.25 D,1.25 D,respectively.The absolute value of cylinder gradually decreased with increasing age (H=739.449,P<0.059),while the constituent ratio of emmetropia increased with the increasing age of children(χ2=585.048,P<0.01). Conclusions The results of refractive screening for children aged 6 months to 6 years should be judged according to their age.Children wih spherical equivalent deviating out of x-±2s and cylinder deviating over P95 should be seen as high-risk of amblyopia and be given further examinations.

摘要: 目的 运用伟伦spot双目视力筛查仪对 6月龄~6 岁儿童进行屈光状态的筛查与分析,寻找各年龄组的屈光筛查界值点。方法 对2018年3—9 月来南京医科大学附属妇产医院门诊就诊的15 342例6月龄~6岁儿童使用伟伦spot双目视力筛查仪进行屈光筛查,按照年龄分组进行统计学描述与分析,寻找合适的界值点。结果 各年龄组等效球镜x-±2s 和柱镜P95的界值点分别是6~12月龄-1.50 D~+2.00 D,2.75 D;1~3 岁-1.25 D~+1.75 D,2.00 D;3~6岁-0.75 D~+1.25 D,1.25 D。各个年龄段柱镜绝对值随年龄增加逐渐减小(H=739.449,P<0.05),等效球镜正视构成比逐渐增高(χ2=585.048,P<0.01)。结论 6月龄~6 岁儿童屈光筛查结果的判断需结合儿童年龄特点,等效球镜数值偏离出x-±2s和柱镜绝对值度数偏离出P95者应列为视力低常和弱视的可疑,给予恰当的转诊,完善进一步相关的眼科检查。
