Effect Of Visual Perception Training And Traditional Treatment On Amblyopia In Children

Objective:To explore the effect of visual perception training and traditional treatment on children amblyopia.Methods:A total of 50 children with amblyopia admitted to our hospital from December 2019 to December 2020 were selected.Among them,2 cases were excluded due to the past history of eye surgery,3 cases were lost to follow-up,and 2 cases did not complete the training and dropped out midway.A total of 43 patients with 64 eyes were included in the study,including 21 males and 22 females,aged 3-13 years,with an average of 7.70±2.60 years.They were randomly divided into control group and observation group.The observation group(22 cases,34 eyes)was given visual perception training for 30min/d for 3 months.In the control group,21 patients(30 eyes)were treated with traditional amblyopia treatment,30min/d.The Best Corrected Visual Acuity(BCVA).stereoscopic vision and Visual Evoked Potential VEP were evaluated before and at 3 months of treatment.The effect of amblyopia in different degree,different types and different ages in the two groups was compared.Correlation data were analyzed by ANOVA and t test.Stereoscopic comparison was performed by rank sum test and Fisher’s exact probability method.Results:1.After 3 months of treatment,BCVA in both groups was higher than before.From Log MAR 0.39±0.24 to Log MAR 0.20±0.21 in the control group;The observation group ranged from Log MAR 0,50±0.25 to Log MAR 0.40±0.20.The BCVA value of the two groups was compared,and the BCVA value of the observation group increased more obviously(P=0.00<0.01).and the difference was statistically significant.2.Stereo vision before,1 month and 3 months of treatment was compared between the two groups.After 1 month of treatment,there was no statistically significant difference in stereoscopic vision between the two groups(P>0.05),but after 3 months of treatment,stereoscopic vision in both groups was improved,with statistical significance(P<0.05).The improvement of stereopsis in the observation group was more obvious than that in the control group(P<0.05),and the difference was statistically significant.3.The BCVA of the.two groups with different degrees of amblyopia was compared,and the BCVA of the patients with moderate amblyopia in the observation group was increased more significantly than that in the control group(P<0.05),and the difference was statistically significant.There was no significant difference in BCVA between mild amblyopia and severe amblyopia between the two groups.The BCVA of different amblyopia causes in the two groups were compared.The BCVA of amblyopia with amblyopia error and anisometropia in the observation group increased more significantly than that in the control group(P<0.05),and the difference was statistically significant.However,intra-group comparison showed that there was no statistically significant difference in BCVA between anisometropia and amblyopia in the observation group.while there was no statistically significant difference in BCVA between anisometropia and amblyopia in the control group.The BCVA of the two groups at different ages was compared,and the BCVA of the observation group of"4-8 years old group" and "9-13 years old group" was increased more significantly than that of the control group(P<0.05),the difference was statistically significant.4.Pair sample t test was used to compare the changes of amplitude and latency of P100 wave before and after treatment in the two groups.The amplitude of P100 wave of visual evoked potential in the two groups was higher than before,and the latency was shorter than before,but the difference before and after treatment was not statistically significant.Conclusions:1.Both visual perception training and traditional treatment can improve BCVA and visual function in amblyopia patients.2.In the same treatment time,visual perception training is better than traditional treatment methods in improving the visual acuity and binocular vision function of amblyopic children,and the effect is faster.It is an effective method for treating amblyopia,which can be further promoted in clinical practice.3.Visual perception training is effective not only for young amblyopia patients,but also for older amblyopia patients.Age should no longer be considered a relative contraindication to the treatment of amblyopia.
