Abstract：Objective To evaluate the effect of visual training on children with myopia, so as to provide the evidence for the intervention of children with myopia. Methods Ninety myopic children aged 8 to 10 years who visited the ophthalmology outpatient department of Zhoushan Hospital in 2021 were selected, and randomly divided into a control group, an intervention group 1, and an intervention group 2, with 30 cases in each group. The control group received medical glasses prescription, the intervention group 1 received a combined intervention of medical glasses prescription and visual training, and the intervention group 2 received only visual training intervention. Basic information, best corrected visual acuity and strabismus degree were collected through questionnaire surveys. Equivalent spherical lens power, positive and negative relative accommodation, amplitude of accommodation, and accommodative facility were measured before and after 1 month, 3 months, 6 months and 12 months intervention. The intervention effects among the three groups were compared using variance analysis of repeated-measures analysis of variance. Results There were no significant differences in gender, age, sleep time, parents' myopia status, outdoor activity time, best corrected visual acuity and strabismus degree among the three groups of children (all P>0.05). The results of analysis of variance for repeated measures revealed no significant differences in spherical equivalent, positive/negative relative accommodation, accommodation of amplitude, and accommodative facility among three groups of myopic children, with no interaction between groups and time (all P>0.05). Significant differences in these parameters were noted across the intervention times within each group (P<0.05). After 6 and 12 months of intervention, the spherical equivalent, positive/negative relative accommodation, amplitude of accommodation, and accommodative facility of the myopic children in the intervention group 1 and intervention group 2 were higher than those before intervention and at 1 and 3 months of intervention (all P<0.05). Conclusions Visual training has certain effect on myopia children. However, no differences were found in the intervention effects of medical glasses prescription alone, or when combined with visual training on myopia children.
