ABSTRACT

Objective To study the clinical effect of short covering method in preventing the recurrence of amblyopia in older children and adolescents. Methods According to the digital table, 146 older children and adolescents ( 200 eyes ) with amblyopia were randomly divided into two groups, each group had 73 patients (100 eyes). The comprehensive therapy group was given 1 month of comprehensive treatment after the corrected visual acuity was more than or equal to 0. 9,and the visual acuity was reviewed within 2-6 months after the termina-tion of treatment. The short covering group was continuously given comprehensive therapy 1 month of treatment after the corrected visual acuity of the amblyopic eye was greater than or equal to 0. 9,then changed to short covering for 2-3 hours every day,in the visual focus time like class or homework time to cover,covering the first half of the year, every month for one time of review on vision. The changes of visual acuity in the two groups were compared before and after treatment,and the qualities of life of patients before and after treatment was compared. Results In the short covering group,all of them had improved visual acuity after treatment. Among them, the improvement of 1 line had 18 eyes,the improvement of 2 lines and above had a total of 82 eyes. In the combined therapy group,the visual acuity decreased after treatment in 70 eyes. Among them,there were 30 eyes with a drop of 1 line,40 eyes with a decrease of 2 lines and more than 2 lines,and the other 30 eyes remained unchanged. Before treatment,100 eyes of all the patients in the short covering group were followed by the center of the eye,after treatment,the treatment of the eyes of 71 cases (90 eyes) turned to the center or the relative center of the eye,there were 2 cases(4 eyes) remained in the center of the eyes. After treatment,in the comprehensive therapy group,73 cases(100 eyes) were still at the center of the eye. Before treatment,there was no statistically significant difference in quality of life between the two groups[(59. 37 ± 6. 72)points vs. (59. 35 ± 6. 76)points,t=0. 145,P>0. 05]. After treatment,the quality of life in the short covering group was significantly better than that in the comprehensive therapy group[(95. 18 ± 4. 21) points vs. (50. 01 ± 2. 59)points,t=7. 655,P<0. 05]. Conclusion The clinical effect of preventing recurrence of amblyopia in older children and adolescents with short covering method is exact, which can effectively improve the visual acuity of patients and watching nature,improve the patients' quality of life,it is worthy of popularization and application.
