近视回归镜控制青少年近视发展的临床观察

目的:临床观察近视回归镜对青少年近视发展的防治作用。方法:随机选取52例在我院视光中心就诊的年龄在9~18岁近视患者配戴近视回归镜作为治疗组,观察裸眼视力变化,屈光度变化,眼轴长度及角膜曲率变化情况.并与52例年龄及屈光度相似的近视患者配戴框架眼镜作为对照组,观察时间12mo。结果:治疗组屈光度增加<0.50D者38例(76眼)有效率73.1%,对照组屈光度增加<0.50D者18例(36眼)有效率34.6%,两组间有显著差异(P<0.01);治疗组裸眼视力下降<2行者39例(78眼)有效率73.6%,对照组裸眼视力下降<2行者10例(20眼)有效率19.2%,两组间差异有显著性(P<0.05);眼轴长度及角膜曲率值变化治疗组与对照组之间无明显差别。结论:近视回归镜对青少年近视发展有延缓作用。

Clinical observation of myopia recovering glasses on controlling juvenile myopia progression

AIM: To observe the preventive and therapeutic effects of myopia recovering glasses (MRG) on young people with myopia.·METHODS: Fifty-two young people with myopia in the treatment group, aged from 9 to 18 years, were randomly selected among patients at the optometric centre in our hospital, who wore MRG. And changes of their naked visual acuity, diopter, axial length and corneal curvature were observed and recorded. The control group was composed of 52 myopia patients with the similar age and diopter, who wore frame glasses. The observation period in this study was 12 months. ·RESULTS: Comparing with the effective rate of 34.6% (18 patients, 36 eyes) on corneal curvature in the control group whose diopter increased less than 0.50D, the effective rate in the treatment group was 73.1% (38 patients, 76 eyes, P<0.01). There were 19.2% (10 patients, 20 eyes) in the control group showing a decrease fewer than 2 lines, but 73.6% (39 patients, 78 eyes, P<0.05) in the treatment group. There were no significant differences of the axial length and corneal curvature between the 2 groups.·CONCLUSION: The results show that the treatment with MRG is able to slow the progression of juvenile myopia.
