青少年儿童近视性屈光参差双眼眼动参数的临床研究

Clinical study on binocular motion parameters of children and adolescents with myopia anisometropia

目的:观察儿童和青少年近视性屈光参差患者双眼眼动参数,初步探讨儿童和青少年近视性屈光参差对眼动参数的影响。方法:病例对照研究。选取2014-09/2016-05于重庆医科大学附属大学城医院就诊的7～14岁儿童及青少年82例,其中正视者(对照组) 47例,近视性屈光参差者(试验组) 35例,检测所有入选者的屈光度、5m和40cm隐斜、梯度性和计算性AC/A比值及调节功能[40cm的调节反应(FCC)、正负相对调节(NRA/PRA)、调节力(AMP)和调节灵敏度(AF)]。结果:两组受检者5m和40cm隐斜度数、40cm FCC、PRA及AC/A比值差异均有统计学意义(P<0. 05); AF、NRA、AMP与正常值最小值的差值差异均无统计学意义(P>0. 05)。结论:近视性屈光参差对儿童和青少年5m和40cm隐斜、40cm FCC、PRA及AC/A比值有显著影响。

AIM： To observe the binocular motion parameters of children and adolescents with myopia anisometropia, and to investigate the influence of myopia anisometropia in children and adolescents on binocular motion parameters. METHODS： A case-control study was conducted. From September 2014 to May 2016, 82 cases of children aged 7 to 14 who were admitted to the University-Town Hospital of Chongqing Medical University were involved. There were 47 emmetropic children as the control group and 35 myopic anisometropic children as the experimental group. We measured the diopter, separated lateral phoria at distance（5m）and near（40cm）, gradient and computational AC/A ratios, accommodative function, as well as accommodative function,including fused cross cylinder（FCC）, negative relative accommodation/ positive relative accommodation（NRA/PRA）, AMP and accommodation facility（AF）. RESULTS： The separated lateral phoria at distance（5m）and near（40cm）, FCC, PRA, gradient and computational AC/A ratios had significant different between two groups（P〈0.05）. Between two groups, AF, NRA had no significant difference found, the same as difference between the detected AMP and minimum normal AMP（P〉0.05）. CONCLUSION： Myopia anisometropia in children and adolescents had a significant effect on separated lateral phoria at distance（5m）and near（40cm）, FCC, PRA, gradient and computational AC/A ratios.
