Abstract: Objective To explore the effects of visual perception training based on binocular push-pull model on visual perception, binocular adjustment and vision of 3 to 6-year-old children with myopia amblyopia.Methods Totally 95 children with myopic amblyopia aged 3 to 6 years treated in our department from June 2018 to January 2020 were selected as the research subjects. They were randomly divided into 47 cases in the control group and 48 cases in the observation group. The control group was given conventional training and the observation group was given visual perception training based on binocular push-pull model, both groups were treated for 6 months. The curative effect, visual perception, binocular adjustment function and vision of the two groups were observed.Results(1) Comparison of curative effects: After training, the total effective rate of the observation group was 95.83% (46/48) and that of the control group was 82.98%(39/47). There was no significant difference(P>0.05). (2) Results of visual perception ability: the scores of non-motor visual perception test(MVPT-4), social skill assessment tool(SSAT-Ⅵ) and Canadian job performance scale(COPM) in the observation group were higher than those in the control group, and the difference was statistically significant(P<0.05). (3)Results of binocular adjustment function: The adjustment response(BCC), negative relative adjustment average(NRA), adjustment amplitude(AMP) and adjustment sensitivity(BAF) in the observation group were higher than those in the control group, and the positive relative adjustment average(PRA) was lower than the control group(P<0.05). (4) Vision: Compared with the control group, the observation group had higher DLP, NLP, AC/A,NPC and average diopter(P<0.05).Conclusion Visual perception training based on binocular push-pull model can improve the binocular adjustment function, visual perception ability and vision of 3 to 6-year-old children with myopic amblyopia.
