近视眼戴镜对外隐斜与调节的影响

目的:探讨不同戴镜情况对儿童、青少年近视患者的外隐斜度及AC/A率的影响。方法:将研究对象分持续戴镜组、未戴镜组和间断戴镜组三组,隐斜测定仪测定外隐斜度,同视机测量AC/A率并进行比较。结果:近视眼持续戴镜组近外隐斜度均值低于未戴镜组及间断戴镜组,而三组间远隐斜度比较无明显差异。持续戴镜组AC/A率均值低于未戴镜组及间断戴镜组。结论:儿童、青少年近视患者易发生外隐斜,近视伴外隐斜者经常戴镜可使外隐斜度降低,AC/A率下降,视疲劳得到一定程度的缓解,减轻眼的近视化。

Influence of wearing glasses for myopia on exophoria and accommodation

AIM:To explore the effect of wearing glasses for myopia on exophoria and accommodation of children and adolescents. METHODS:They were divided into three groups of continued wearing glasses,no wearing and interrupted wearing glasses.Exophoria was measured with heterophorometer.The AC/A ratio was measured with a synoptophore. RESULTS:The mean near exophoria of continued wearing group had significant difference with that of no wearing and interrupted wearing groups.The mean distant exophoria of three groups had no significant difference.The average value of AC/A ratio in continued wearing group has significant difference with that of no wearing and interrupted wearing groups. CONCLUSION:Myopia of adolescents and children was prone to exophoria.Exophoria myopia with continued wearing of glasses can decrease AC/A ratio and exophoria.relieve asthenopia,and reduce myopia at certain level.
