A growing body of neuroscientific literature demonstrates that most vision processes happen as a result of inside-out rather than outside-in neural pathways. Training systems and methods are often being counselled, promoted, and accepted as solve-it-all approaches without statistic and scientific evidence that training improvement can be transferred from training sessions to competitive performance.展开更多

Methods: 100 cases of juvenile myopia treated in our hospital from December 2017 to December 2018 were divided into reference group and experimental group by lot, with 50 cases in each group. The reference group received medical optometry according to the reference requirements, and the experimental group received visual training on the basis of the reference group. The changes of ocular axis length of the two groups after the intervention and the adjustment lag of the two groups before and after the intervention were compared. Results: the length of ocular axis in the experimental group was lower than that in the reference group, and the comparison between the groups had statistical value (P < 0.05);In the comparison of adjustment lag, there was no difference between the two groups before intervention (P > 0.05);After the intervention, the experimental group was lower than the reference group, and there was significant difference between the groups (P < 0.05). Conclusion: in order to reduce juvenile myopia, visual training can delay the growth of ocular axis length, reduce the amount of adjustment lag and myopia, which is conducive to the healthy growth of adolescents.展开更多
