Clinical Study On Push-Pull Model Training For Amblyopia

Objectives: Amblyopia is a common disease in children with eye diseases.The main hazard not only causes vision loss,but also hinders the establishment of binocular stereopsis.Although there are many methods for treatment of amblyopia,there are still some problems that are difficult to solve,such as the patient’s slow vision improvement,long treatment period,difficulty in improving binocular stereoscopic function,poor compliance and obscuring the dominant eye,affecting the appearance of the patient and even causing psychological problems.We randomly selected 108 children with amblyopia to use the push-pull model for 20 minutes of training.By observing the changes of distance vision,near vision and near stereoscopic vision before and after training,we explored the clinical effect and application value of push-pull model training in amblyopia treatment.Mothods: A total of 108 children(108 eyes)with amblyopia diagnosed in the ophthalmology clinic of Yuding Hospital from September 2017 to July 2018,including 61 females and 47 males,with an average age of 6.32±2.45 years old.Amblyopia was divided into mild amblyopia 59 eyes(59/108),moderate amblyopia 49 eyes(49/108).There were 49 cases of ametropic amblyopia and 49 cases of anisometropic amblyopia.There were 29 cases of amblyopia(selection of eyes with relatively poor vision)and 79 cases of monocular amblyopia.Refractive status: 6 cases of myopia amblyopia,92 cases of hyperopia amblyopia,hyperopic refractive status: 5.74 ± 2.82 D.108 children with amblyopia were wearing virtual reality binocular screening tools to develop a visually perceptual learning task for personalized training of push-pull models.Both eyes were trained for 10 minutes and paused for 10 minutes,and the push-pull model was trained again for 10 minutes.Statistical analysis was performed on distance vision,near vision and near stereopsis before and after training.Result: The average distance vision of 108 children(108 eyes)with amblyopia before training was 0.56.The average distance vision after training was 0.65.The change of distance vision before and after training was in accordance with the normal distribution.Paired t-test,P=0.00,the difference was statistically significant.Significance(P<0.05);the distance vision distribution before and after training was consistent with the normal distribution.Pearson correlation analysis was used to analyze the correlation between distance vision before and after training.The correlation coefficient was r=0.836.The average near vision before training was 0.31,and the average near vision after training was 0.39.The change of near vision before and after training was in accordance with thenormal distribution.The paired t test was used,P=0.00,the difference was statistically significant(P<0.05).The near vision distribution was consistent with the normal distribution.Pearson correlation analysis was used to analyze the correlation of near vision before and after training.The correlation coefficient was r=0.855.Changes in the near-stereoscopic view of both eyes before and after training: the average near stereoscopic view before training was 415.00′′,and the average near stereoscopic view after training was 343.80′′.The changes of the near-stereoscopic view of both eyes before and after training were in accordance with the normal distribution,using paired t-test,P=0.013,two There were significant differences between the two groups(P<0.05).The distribution of near-stereoscopic distribution of both eyes before and after training was consistent with normal distribution.Pearson correlation analysis was used to analyze the correlation between near stereoscopic vision before and after training.,correlation coefficient r = 0.992.The changes of far vision,near vision and near stereo acuity before and after mild and moderate amblyopia were consistent with normal distribution.The measurement data were compared by t test.There was no statistical difference between the two groups(P > 0.05).The changes of far and near vision and near stereoscopic sharpness of children with ametropia and anisometropic amblyopia were consistent with normal distribution.The measurement data were compared by t test.There was no statistical difference between the two groups(P >0.05).Conclusion: The distance vision and near vision of 108 children with amblyopia were improved by the push-pull model,and the near-stereoscopic function of both eyes was improved.Push-pull model training has no difference in the treatment effect of mild to moderate amblyopia.Push-pull model training has the same therapeutic effect on refractive error and anisometropic amblyopia.The patient’s distance vision and near vision are rapidly improved in a short time(20 minutes),and the push-pull model training is combined with multimedia technology.The content is rich,the forms are diverse,the pertinence is strong,and the interest is strong,which improves the patient’s compliance.The push-pull model training is a binocular vision treatment,which does not need to cover the dominant eye,and reduces the psychological problem caused by the amblyopia patient using the eye mask to cover the dominant eye.The push-pull model training method can be used as a new method for amblyopia treatment or as an auxiliary method for traditional amblyopia treatment in clinical application and promotion.
