Suresight手持式自动验光仪筛查儿童屈光异常情况分析

The Analysis of Abnormal Refraction in Children by Using Suresight Hand-held Autorefractor

目的 筛查分析昆明市区儿童屈光异常情况,及时发现超出正常范围可能影响视力的屈光异常,以便早期诊断和治疗弱视.方法 使用Suresight手持式自动验光仪对昆明市区年龄3～6岁1 880名儿童进行屈光筛查.并对来院复查儿童进行睫状肌麻痹验光以明确诊断.结果 筛查屈光异常异常261人,共计381只眼,屈光异常眼检出率为10.13％.3、4、5、6岁儿童屈光异常眼的发生率分别为8.44％、10.32％、10.53％、11.90％.x2检验均差异无统计学意义(P＞0.05).自然状态下Suresight手持式自动验光仪筛查的屈光异常结果与睫状肌麻痹比较球镜相关系数r=0.535 (P＜0.01).柱镜相关系数r=0.762 (P＜0.01),相关性均有统计学意义(P＜0.01).结论 Suresight手持式自动验光仪适用于学龄前儿童的屈光筛查,对屈光筛查异常者应尽早进行静态屈光检查,明确诊断.3岁儿童即存在明显的屈光异常,并随着年龄的增长,屈光异常的发生率不断增加.

Objective To find out timely the condition of ametropia beyond normal ranges that might affect the eye vision by screening and analyzing the abnormal situation of children with ametropia in Kunming so as to make the diagnosis and treatment for amblyopia.Methods Refractive screening was performed among 1880 children aged 3 to 6 years old with Suresight hand-held autorefractor and cycloplegic refraction optometry was performed for those back to hospital so as to make a definite diagnosis.Results The screening indicated 261 of them coming to 381 eyes were with ametropia.The detection rate of ametropia eyes was 10.13%.The incidences of the ametropia in children aged 3,4,5 and 6 years old were 8.44%,10.32%,10.53% and 11.90% respectively.The chi-square test showed no statistical difference.Compared the ametropia results of Suresight hand-held autorefractor screening under the natural conditions with cycloplegic refraction,relatively spherical correlation coefficient was r=0.535(P < 0.01) and cylindrical lens correlation coefficient was r=0.762(P < 0.01).The correlation was statistically significant.Conclusion Refractive screening with Suresight hand-held autorefractor is suitable for preschool children.Static refractive examination should be conducted on those with ametropia as soon as possible so as to make a clear diagnosis.There exists obviously abnormal refraction in children aged 3,and the incidence of abnormal refraction increases with age continuously.
