两种方法对儿童视力筛查结果分析比较

目的 通过两种方法对儿童视力筛查结果分析比较,探讨美国伟伦公司生产的Suresight手持式自动验光仪对2～6岁儿童屈光不正(包括散光、远视、近视和屈光参差)中的远视及近视筛查率的准确性、可行性及可信性.方法 采用美国伟伦公司生产的Suresight手持武自动验光仪对228名(456眼)2～6岁儿童进行视力筛查.分别用方法1与方法2(方法见下1.3)对筛查结果进行分析比较.结果 456眼中用方法1检出屈光不正的有58眼,远视21眼,近视2眼:用方法2对这58眼重新判定,检出远视7眼,近视10眼.方法1与方法2(方法见下1.3)分别对远视及近视的检出率存在差异性(x2值分别为12.07,6.12,P值均＜0.025).结论 方法1对儿童远视的检出率较方法2高,对近视的检出率较方法2低.Suresight手持式自动验光仪对儿童远视及近视筛查结果的准确性、可行性及可信性还需进一步探究.

Analysis of comparing two different methods in diagnosis of the abnormal eyesight on screening eyesight

OBJECTIVE To compare the two different ways in diagnosis of the abnormal eyesight of children from 2 years to 6 with Hand-held instrument automatically optometry Suresight made by America Welchallyn Co.,and observe the veracity,feasibility and creditability of the two ways.METHODS 228 children years between 2 and 6 were screened with Hand-held instrument automatically optometry Suresight,compared the screening results with two different diagnosing ways.RESULTS 58 eyes were diagnosed with abnormal diopter,21 eyes were hypermetropia,and 2 eyes were myopia.Among 456 eyes,58 eyes had retested,7 were hypermetropia,and 10 were myopia.There were marked difference between the detection rates of hypermetropia and myopia(P﹤0.025).CONCLUSION The first method checked-up hypermetropia was better than that of the second method,but less myopia.Hand-held instrument automatically optometry named Suresight should be more explored in using screening children’s eyesight.
