Comparison of traditional training and push‐pull training for the binocular visual function in anisometropic amblyopia

Abstract

PurposeTo compare the binocular visual function in anisometropia amblyopia used by Push‐pull Training and traditional training.MethodsA total of 64 children with anisometropia amblyopia were enrolled in our study and randomly divided into two groups. After wearing glasses to correct refractive errors in the first three months, the experimental group were treated with push‐pull training, and the the control group were treated with traditional covering method and visual stimulation for a period of 6 months. Then binocular visual functio was measured by synoptophore and random‐dot stereograms(RDS).ResultsThe average visual acuity of the amblyopic eyes in the experimental group was increased 4.2±2.6 lines and the control group was increased 4.52±1.9 lines (p>0.05). The average score of far stereoscopic in experimental group increased 9.3±4.7 points and the control group increased 10.1±5.6 points(P>0.05.)There was no statistical difference between the two groups.The average score of large‐scale RDS stereoscopic in experimental group increased 14.2±9.7points and the control group increased 12.1±7.5points (P<0.05). The average score of the acuity stereopsis RDS in experimental group was increased 19.3±10.2 points and the control group increased 13.5±8.4 points(P<0.05). The average score of cross stereoscopic RDS in experimental group increased 14.9±6.8 points and the control group increased 11.8±5.7 points (P<0.05). The average score of uncross stereoscopic RDS in experimental group increased 17.1±7.9 points and the control group increased13.4±6.6 points (P<0.05). There was statistical difference between the two groups.Conclusionscompared with traditional cover training methods, the push‐pull training method can not only achieve the same visual acuity, but also establish better binocular vision function.
