摘　　要：目的　探讨不同的戴镜情况对近视眼、远视眼AC/A比率的影响。方法　近视眼 2 32例 ,远视眼 62例。经扩瞳验光后 ,复验时戴全矫正眼镜 ,用TSJ -3型同视机测量AC/A比率。平时戴镜情况分持续戴镜、未戴镜和间断戴镜三组。按屈光性质分别行各组的统计分析 ,并同正常人作对比。结果　持续戴镜、未戴镜和间断戴镜各组的AC/A比率均值 :近视眼依次为 :3 1 0± 1 79△/D、 3 93± 1 92 △/D和 3 80± 2 4 0 △/D。远视眼依次为 :2 35± 1 53△/D、 1 1 7± 0 90 △/D和 1 4 7± 1 0 4 △/D。分别同正常人对比 ,一组同其无显著差异 (P >0 0 5) ;二、三组与其均有显著或极显著性差异 (P <0 0 5或P <0 0 1 )。结论　屈光不正患者持续戴镜对AC/A比率的影响大于未戴镜和间断戴镜者 ,并能使AC/A比率恢复或接近正常。The chapter is order to find out the effect of wearing of glasses for AC/A ratio of ametiopes in different conditions. Methods The AC/A ratio of 232 cases of myope and 62 cases of hyperope were detected with TSJ 3 synoptophore. After mydriasis and optometry, When they weared orthotic glasses, we detected the AC/A radio again. They were divided into three groups of continued wearing of glasses No wearing and interrupted wearing according status of wearing glasses. Accoreding to the statistical analysis of AC/A ratio of refrangibility in different groups, their AC/A ratios were compared with normal people′s. Results The AC/A ratio average value in continued wearing no wearing and interrupted wearing: myope in proper order: 3 10±1 79%,3 93±1 92 △ /D and 3 80±2 40 △ /D; hyperope: 2 35±1 53 △/D, 1 17±0 09 △/D and 1 47±1 04 △ /D. The first group has no significant difference with normal people (p>0 05). The second group and third group have significant or extro significant difference with normal people (p<0 05 or p<0 01), Conclusion The effect of continued wearing of glasses is more obvious than no wearing′s and interrupted wearing′s in AC/A ratio of ametrope. It can make AC/A ratio recovered or close to normal.
