The efficacy of orthokeratology and fine training for patient with ametropic amblyopia

Abstract

Objective To evaluate the efficacy of orthokeratology combined with monocular partial occlusion and fine training for the treatment of ametropic amblyopia. Methods A prospective study.The data of 86 children with ametropic amblyopia in this hospital from Dec.2016 to May 2018 were analyzed.All cases were randomly divided into two groups, with each group of 43 cases.All cases were partially coverd with a single eye.The control group adopted fine training.The research group underwent orthokeratology combined with fine training, and both groups were treated for 6 months. Results The total effective rate of the research group(97.67%)was higher than that of the control group(81.40%)(χ2=4.468, P=0.035). The best corrected visual acuity (LogMAR) of the research group (0.1±0.01) was better than that of the control group (0.15±0.02) (t=14.663, P=0.000). Visual sensitivity of the research group was higher than that of the control group(t=4.428, P=0.000). The adjustment flexibility and adjustment range of the research group were greater than that of the control group, and the adjustment hysteresis of the research group was less than that of the control group(P=0.000). Conclusion The combination of orthokeratology, monocular partial occlusion and fine training is effective for the treatment of children with ametropic amblyopia.
