Clinical Observation of the Intervention Effect of"Eye Moving Exercise"on Presby-opia
OBJECTIVE To observe the intervention effect of"eye moving exercise"on presbyopia.METHODS A total of 61 presbyopic patients(61 eyes)treated at the Eye Hospital,China Academy of Chinese Medical Sciences from March 2021 to October 2021 were randomly divided into a treatment group of 30 cases(30 eyes)and a control group of 31 cases(31 eyes).The"eye moving exercise"therapy and health education were respectively given to the two groups,and both were observed for eught weeks.The visual nearsightedness,near point adjustment,reading vision and speed,modulation transfer function(MTF)cutoff frequency,mean object scatter index(Mean OSI),and subjective symptom scores of the patients were measured before and after treatment.RESULTS There were no statistically significant differences in visual nearsightedness,near point adjustment,reading vision,reading speed,MTF cutoff frequency,Mean OSI,and subjective symptom scores between the two groups before treatment(P＞0.05).(1)Nearsight diopter:After treatment,there were no statistically significant differences in nearsight diopter between the two groups and within each group(P＞0.05).(2)Near point adjustment:After treatment,the treatment group showed a significant decrease in near point adjustment compared to before treatment(t=7.581,P=0.000),the control group showed no statistically significant difference compared to before treatment,as well as when comparing with the treatment group after treatment(P＞0.05).(3)Reading speed and reading vision:After treatment,the treatment group exhibited an increase in reading speed,which was statistically significant(t=-2.273,P=0.031).However,the control group showed no statistically significant difference compared to before treatment,as well as when comparing with the treatment group after treatment(P＞0.05).Reading vision in the treatment group significantly improved after treatment(Z=-3.669,P=0.000),whereas the control group showed no statistically significant difference compared to before treatment(P＞0.05).When comparing the two groups after treatment,the treatment group was superior to the control group in terms of reading vision,and the difference was statistically significant(Z=-1.894,P=0.047).(4)Mean OSI and MTF cut off frequency:After treatment,the control group showed a significant increase in Mean OSI compared to before treatment(Z=-2.884,P=0.004),while the treatment group showed no statistically significant difference compared to before treatment(P＞0.05).When comparing the two groups after treatment,the treatment group was superior to the control group in terms of Mean OSI,and the difference was statistically significant(Z=-2.835,P= 0.005).The MTF cutoff frequency in the control group significantly decreased after treatment(t= 4.439,P=0.000),while the treatment group showed no statistically significant difference compared to before treatment(P＞0.05).When comparing the two groups after treatment,the treatment group had a higher MTF cutoff frequency than the control group,and the difference was statistically significant(t=3.019,P=0.004).(5)Subjective symptom scores:After treatment,the treatment group showed a significant decrease in subjective symptom scores compared to before treatment(t=7.607,P=0.000),while the control group showed no statistically significant difference compared to before treatment(P＞0.05).When comparing the two groups after treatment,the treatment group had lower subjective symptom scores than the control group,and the difference was statistically significant(t=-2.527,P=0.014).(6)Clinical efficacy:The effective rate was 13.33%in the treatment group and 9.68%in the control group.There was no statistically significant difference between the treatment group and the control group(P＞0.05).CONCLUSIONS"eye moving exercise"improves reading vision,reading speed,near point adjustment,and subjective symptoms such as reading fatigue,eye soreness,and dizziness in presbyopic patients to varying degrees.It can be promoted as an intervention measure for presbyopia.
