假性近视、真性近视、混合近视正相对调节研究

目的:探讨假性近视、真性近视、混合近视正相对调节差异。方法:以2008年寒假和暑期到我院小儿眼科就诊的17岁以下初次被诊断为近视的67例患者(远视力<1.0,近视力≥1.0,电脑验光为近视)为研究对象,检查他们的5m时正相对调节后,通过10g/L阿托品睫状肌麻痹后分成3组:真性近视组、假性近视组、混合近视组,对比三组5m时正相对调节。统计学分析:方差分析LSD法对比真性近视、假性近视、混合近视三组正相对调节差异的显著性。统计软件为SPSS11.5软件。结果:真性近视与假性近视组间5m时正相对调节差异显著;真性近视与混合近视组5m时正相对调节差异显著。假性近视与混合近视组的5m时正相对调节差异无显著性。结论:5m时正相对调节力≤1.25D的近视患者有调节成分。

Positive relative accommodation of pseudo-myopia,true myopia and mixed myopia

AIM:To observe the differences of positive relative accommodation of pseudomyopia,true myopia and mixed myopia.·METHODS:Sixty-seven patients under 17 years old with myopia(distant vision < 1.0,near vision≥1.0) were firstly diagnosed as myopia when they were checked in the ophthalmology clinic.After ciliary muscle paralysis,they were divided into three groups,namely:myopia group,pseudomyopia group and mixed myopia group.The positive relative accommodation(5 meters) had been checked before they were divided into 3 groups.Statistical Analysis:Multiple comparison of ANOVA was used to determine the difference among three groups of myopia.·RESULTS:The difference of positive relative accommo-dation was significant between true myopia group and pseudomyopia group,so was between true myopia group and mixed myopia group.·CONCLUSION:There seems to be accommodation when the positive relative accommodation of the patient with myopia is less than 1.25D.
