2种传统眼保健方法防控青少年近视的初步评价

The Preliminary Evaluation of Two Traditional Eye Care Methods on the Prevention of Adolescents Myopia

目的观察2种传统眼保健方法延缓青少年近视的效果,及其对青少年眼轴、角膜散光的影响,评价这一传统疗法防治青少年近视的安全性。方法 186名学生分别来自七、八年级7个班,将这7个班随机分为2组:治疗组练习明目功,对照组练习眼保健操。观察2组在干预前、后3个月裸眼视力、屈光度、眼轴、角膜散光的变化。结果近视:明目功组延缓近视效果优于眼保健操组(P=0. 033);组内主导眼和非主导眼比较,裸眼视力、屈光度都有所改善,但无差异(P> 0. 05)。正视:2组延缓青少年近视化效果无差异(P=0. 663)。眼轴:2组眼轴都有所增长,但无差异(P=0. 505)。角膜散光:2组角膜散光都有所减少,但无差异(P=0. 55)。结论 2种传统眼保健法防治青少年近视具有安全性,明目功效果优于眼保健操。

Objective To observe the effect of teenager myopia control and the change of axis oculi and cornea astigmatism,and to evaluate the safety of two methods of traditional eye care on the prevention of adolescents myopia.Methods A total of 186 students in the seventh grade come from 2 classes,and in the eighth grade come from 5 classes,according to complete randomized block design,they were divided into treatment group used Mingmugong intervention and control group used eye exercises intervention.The change of uncorrected visual acuity,diopters,axis oculi and cornea astigmatism before intervention and after intervention for 3 months was observed.Results The eyes with myopic diopter:the effect of the treatment group was better than that of the control group(P=0.033).Among groups,the efficient comparison between dominant eye and non-dominant eye,the uncorrected visual acuity and the diopters have improved,but had no statistical significance(P>0.05).The eyes without hyperopia diopter and myopic diopter:there were no significant difference(P=0.663).Axis oculi of the two groups increased,but there was no significant difference(P=0.505).Cornea astigmatism of the two groups decreased,but there was no significant difference(P=0.55).Conclusion Two methods traditional eye care on the prevention of adolescents myopia has security,and the effect of Mingmugong is better than eye exercises.
