AIM: To explore the effects of red light flashing therapeutic instrument combined with distance visual training through reading red visual acuity chart on myopic amblyopia in children.

METHODS: Totally 112 cases of children patients with myopic amblyopia treated in our hospital were assigned to the control group and the observation group. The control group was given short covering method and short-range visual function training, and the observation group was given red light flashing therapeutic instrument combined with distance visual training through reading red visual acuity chart on the basis of the above treatment. The clinical efficacy, refractive dynamic changes, the BCVA and amblyopia recurrence rate were compared between the two groups.

RESULTS: The total clinical effective rate in the observation group was significantly higher than that in the control group(P<0.05). Before and after treatment, the myopic diopter was no significant difference in the observation group(P>0.05), the control group gradually increased myopic diopter with time(P<0.05). The myopic refraction, the change value of average annual refraction and the recurrence rate of amblyopia after 1y of treatment in the observation group was lower than that in the control group(P<0.05). The BCVA after 1y of treatment was significantly higher than that after 6mo of treatment(P<0.05).

CONCLUSION: Red light flashing therapeutic instrument combined with distance visual training through reading red visual acuity chart for children patients with myopic amblyopia can effectively reduce the change value of average annual refraction, correct the best visual acuity, and reduce the risk of amblyopia recurrence.
