摘　　要：目的比较屈光不正性、屈光参差性及斜视性弱视患者的位置辨别功能差异以及单眼弱视双眼间位置辨别差异。方法选取在广西视光中心就诊的139例(237眼)弱视患者,按弱视类型分为屈光不正性弱视组40例(80眼)、屈光参差性弱视组61例(82眼)、斜视性弱视组38例(75眼),检测3组弱视位置辨别功能并进行比较分析。结果 3组弱视位置辨别功能检测结果均集中在2～4级之间,中位数均为3级,3组位置辨别功能结果比较,差异无统计学意义(Hc=0.530,P>0.05)。单眼弱视双眼位置辨别功能比较,差异无统计学意义(MH=1.837,P>0.05)。单眼弱视眼与双眼弱视眼位置辨别功能比较,差异无统计学意义(Z=-0.588,P>0.05)。结论屈光不正性、屈光参差性及斜视性弱视儿童位置辨别功能不存在差异,单眼弱视双眼位置辨别功能无差异,单眼弱视眼与双眼弱视眼位置辨别功能相似。Objective To investigate the distinction of position discrimination in children with ametropic amblyopia,anisometropic amblyopia or strabismic amblyopia and the difference of position discrimination between the amblyopic eye and the fellow eye in monocular amblyopia.Methods One hundred and thirty-nine amblyopia（237 eyes） from the Guangxi Visual Science and Optometry Center were selected and divided into ametropic amblyopic group（40 cases,80 eyes）,strabismic amblyopic group（61 cases,82 eyes） and anisometropic amblyopic group（38 cases,75 eyes）.Of all the amblyopia were detected by position discrimination detective program and the result were analyzed.Results Most of position discrimination in three groups were located from level 2 to level 4,and the median was level 3,there was no statistical difference in position discrimination in three groups（Hc=0.530,P0.05）.There was no statistical difference in position discrimination between the amblyopic eye and fellow eye in monocular amblyopia（MH=1.837,P0.05）.There was also no statistical difference in position discrimination between the monocular amblyopic eye and binocular amblyopic eye（Z=-0.588,P0.05）.Conclusion The position discrimination of children with ametropic amblyopia,anisometropic amblyopia or strabismic amblyopia has no difference.The position discrimination of amblyopic eye is similar with that of fellow eye in monocular amblyopia,and the position discrimination of monocular amblyopic eye and binocular amblyopic eye is also similar.
