Application Study of Diversified Visual Function Training in Children with Anisometropic Amblyopia
Objective:To explore the application effect of diversified visual function training in children with anisometropic amblyopia.Method:A total of 82 children with anisometric amblyopia treated in People's Hospital of Qianxinan Buyei and Miao Autonomous Prefecture from March 2021 to September 2022 were selected and divided into two groups according to random number table method,with 41 cases in each group.Both groups received covering therapy,the control group received routine training,and the observation group received diversified visual function training,which lasted for 3 months.Visual acuity,visual evoked potential,stereoscopic function and contrast sensitivity were compared between the two groups.Result:Before intervention,there were no significant differences in visual acuity,visual evoked potential,stereoscopic function and contrast sensitivity between the two groups(P>0.05).After intervention,the naked vision and best corrected visual acuity(BCVA)in the observation group were higher than those in the control group,the latency of spatial frequency at 1° and 15° in the observation group were shorter than those in the control group,the amplitude in the observation group were higher than those in the control group,the stereoscopic acuity in the observation group was lower than that in the control group,and the contrast sensitivity of spatial frequency at 1.5,3,6,12 and 18 c/d in the observation group were higher than those in the control group,the differences were statistically significant(P<0.05).Conclusion:Diversified visual function training can effectively improve the visual acuity and stereoscopic function of children with anisometropic amblyopia,and improve the contrast sensitivity.
