[摘要] 目的 分析青少年佩戴角膜塑形镜和框架眼镜后调节反应差异性。 方法 选择2015年1月~2016年12月于我院就诊的98例青少年近视患者,根据其矫治方式分为两组,其中有40例佩戴角膜塑形镜(观察组),58例佩戴框架眼镜(对照组),对比两组患者初次戴镜时以及戴镜1年后双眼调节反应、调节滞后的差异。 结果 对照组戴镜1年后与初次戴镜时相比,有效调节刺激、调节反应和调节滞后均有明显差异(P<0.05)。戴镜1年后,观察组有效调节刺激、调节反应大于对照组,调节滞后小于对照组(P<0.05)。 结论 青少年近视患者佩戴角膜塑形镜1年后,其调节反应较佩戴框架眼镜明显更加灵敏,可降低调节滞后。

[Abstract] Objective To analyze the difference of accommodative response after wearing orthokeratology lenses and frame glasses in adolescents. Methods 98 pre-adolescent myopes from January 2015 to December 2016 were selected and divided into two groups according to the way of correction, observation group (n=40) with orthokeratology lenses and control group (n=58) with frame glasses.The difference of accommodative response and accommodative lag between the two groups were compared when they were wearing glasses for the first time and wearing glasses for 1 years. Results In the control group, after 1 years of wearing glasses, there were significant differences in the effective regulation stimulus, the accommodative response and the accommodative lag between the initial wearing and the first wearing glasses (P<0.05). After 1 years of wearing glasses, in the observation group, Effective regulatory stimulus and the regulation response were greater than the control group, and the adjustment lag was less than the control group (P<0.05). Conclusion 1 years after wearing orthokeratology lenses, the accommodative response of adolescents with myopia is significantly more sensitive than that of frame glasses, and the accommodative lag can be reduced.

我國近视眼发病率较高,青少年近视发生率为50% ~ 70%左右[1-2],如何预防、矫正近视是人们目前广为关注的一个问题,对近视眼的发病机制,一直有多种研究理论,其中调节理论是在研究中较受关注的重点[3-4]。有文献报道显示[5],近视眼的调节反应低于正视眼。近年来,角膜塑形镜已被广泛应用于青少年近视的干预当中,并取得了良好的临床效果,但具体机制还没有被完全阐明[6]。因此,本研究通过分析青少年佩戴角膜塑形镜和框架眼镜后调节反应存在的差异性,现总结并报道如下。
1 资料与方法
1.1 一般资料
选取2015年1月~2016年12月于我院就诊的98例青少年近视患者,所有患者均进行了医学验
光,行角膜曲率、角膜地形图检查。严格按照角膜接触镜验配流程进行试戴。纳入标准:屈光度- 1.0D-5.0D,散光小于1.0D;双眼矫正视力在1.0或以上;双眼无其他眼部疾病,无屈光参差;主导眼为右眼。根据其自愿矫治方式分为两组,其中40例佩戴角膜塑形镜患者为观察组,58例佩戴单焦点框架眼镜患者为对照组。……
