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.
