手持自动验光仪在学龄前儿童验光中的应用

Clinical research of HAR-800 hand-held autorefractor on preschool children

目的:评估HAR-800手持验光仪对学龄前儿童屈光检查的准确性。方法:对173例学龄前儿童进行检影验光,首先行HAR-800手持验光仪检查(试验组),然后应用阿托品眼膏进行扩瞳检影验光(对照组),比较两种检影验光的屈光差异。结果:试验组球镜为1.59±0.61D,对照组为3.15±0.72D,两者有显著统计学差异(t=-82.89,P<0.01),且具有相关性(r=0.87,P<0.01)。试验组散光为-0.62±0.51D,对照组为-0.48±0.55D,两者有显著统计学差异(t=-6.97,P<0.01),且具有显著相关性(r=0.76,P<0.01)。结论:HAR-800手持验光仪不能替代阿托品检影验光,但其结果可以反映学龄前儿童的屈光状况。

AIM：To evaluate the accuracy of HAR-800 hand-held autorefractor on preschool children.METHODS：Totally 173 preschool children were included in this study. They were performed HAR-800 hand-held autorefractor examination before using atropine ointments for cycloplegic refraction. The results from HAR-800 refractor were set as experimental group, and the cycloplegic refraction were controlled group. The refractions between the two groups were compared and analyzed.RESULTS： The sphere was 1.59±0.61D in the experimental group, while 3.15±0.72D in the controlled group.The difference was significant （t=-82.89, P0.001）, however, there was a significant correlation （r=0.87, P0.001, Pearsons correlation analysis）. The cylinder difference was also significant （t=-6.97,P0.001） and a significant correlation also existed between the two groups（r=0.76,P0.001, Pearsons correlation analysis）.CONCLUSION： The HAR-800 hand-held autorefractor can not replace cyclopegic refraction using atropine, but the results can reflect the preschool children refraction.
