Study On TCM Syndrome Differentiation And Distribution Of Syndrome Elements Of Regulatory Asthenopia

Background: China is in the process of rapid development of modern science and technology.Due to the rapid development of the Internet,people’s daily life and work have been inseparable from various information platforms and intelligent devices.While enjoying the convenience of life brought by the progress of science and technology,the number of people who suffer from visual fatigue due to excessive use of electronic products is also increasing.Asthenopia is a common and chronic disease in ophthalmology.The treatment of asthenopia by traditional Chinese medicine has a long history.However,there are many deficiencies in the study of syndrome differentiation and syndrome differentiation,Therefore,based on the modern literature research and clinical investigation,the TCM syndrome differentiation and the distribution of TCM syndrome elements of regulatory asthenopia are further discussed,which provides certain scientific basis and research data for the prevention and treatment of TCM in clinic.Objective: This paper analyzes the common TCM symptoms of regulatory asthenopia,extracts the syndrome elements of disease and disease location,and discusses the TCM syndrome elements,syndrome differentiation and classification of regulatory asthenopia and the distribution law of visual function data.Methods: All statistical data were analyzed by SPSS17.0,and the measurement data were expressed by means of mean ± standard deviation.P < 0.05 is the difference of test results,P < 0.01 is the difference of test results.Statistical test method: variance analysis is used for measurement data conforming to normal distribution,rank sum test in nonparametric test is used for measurement data not conforming to normal distribution,and chi square test is used for counting data.Result:1.Among 85 patients with regulatory asthenia,57(67.06%)were in the over regulation group,14(16.47%)in the under regulation group,and 14(16.47%)in the poor flexibility group,39(45.88%)in men and 46(54.12%)in women,46/85),the average age was 25.07 + 8.70 years(10 years old-40 years old).There was no significant difference in incidence rate and age of onset between male and female(P >0.05),but the age of onset of adjustment flexibility group was 30.71 + 5.08 years,higher than that of over regulation group and insufficient adjustment group(P < 0.01).2.Among 85 patients with regulatory asthenopia,3 were mild(3.53%,3 / 85),49 were moderate(57.65%,49 / 85),and 33 were severe(38.82%,33 / 85).There was a significant difference(P < 0.01).3.Among 85 patients with regulatory asthenopia,81(95.29%,81 / 85)had ametropia,73(85.88%,73 / 85)had corrected vision of 1.0 or more.4.There was no significant difference in the abnormal rate of AC / A,BCC,NRA and pra among the groups(P>0.05).5.The high frequency local symptoms of accommodation asthenopia were: non durable vision,vision loss,eye dryness,eye itching,eye distention(frequency > 50%);the high frequency pulse was: stringed pulse,several pulse,fine pulse(frequency >20%);the high frequency tongue was: red tongue,yellow tongue coating,light tongue texture,white tongue coating,thin tongue coating(frequency > 20%).6.The factors of high frequency disease syndrome of regulatory visual fatigue are qi depression,yin deficiency and Qi deficiency(frequency > 30%),and the factors of high frequency disease syndrome with poor flexibility are yin deficiency,qi depression and phlegm dampness;the factors of high frequency disease syndrome of regulatory visual fatigue are liver,spleen and heart(frequency > 30%).7.85 cases of regulatory visual fatigue,38 cases of liver kidney yin deficiency syndrome(45.90%),20 cases of liver depression and spleen deficiency syndrome(22.40%),18 cases of yin deficiency and fire hyperactivity syndrome(21.20%),9cases of Qi and blood deficiency syndrome(10.60%);4 TCM Syndromes of regulatory visual fatigue and AC / a value,BCC value,NRA value,PRA value were analyzed,the results were not correlated(P > 0.05).Conclusion: 1.The incidence of regulatory visual fatigue is mainly young people with high learning and working pressure,and the prevalence rate of the severity of visual fatigue is moderate and severe.There is no difference in the prevalence rate and age between men and women,but the incidence age of patients with poor regulatory flexibility is significantly higher than that of patients with excessive and insufficient regulation.2.Accommodative visual fatigue is easy to occur in the myopia group whose corrected vision of both eyes can reach 1.0 or above.3.The abnormal rates of AC / a value,BCC value,NRA value and pra value were not significantly different in the three different cases of regulatory visual fatigue: over regulation,under regulation and poor flexibility.4.The Chinese medicine symptoms of regulatory asthenopia are mainly local symptoms of the eyes,accompanied by systemic symptoms.The high frequency local symptoms are in order: not durable vision,vision loss,dry eyes,itchy eyes,eye pain;the high frequency pulse is in order: String pulse,number pulse,fine pulse,high frequency tongue is in order: red tongue,yellow tongue coating,light tongue,white tongue coating,thin tongue coating.5.The key factors and pathogenesis of high frequency syndrome of regulatory asthenopia are: qi depression,yin deficiency and Qi deficiency;the key factors of high frequency syndrome are: liver,spleen and heart.6.Regulatory visual fatigue can be roughly divided into four TCM syndrome differentiation types,which are: liver kidney yin deficiency,liver depression and spleen deficiency,yin deficiency and fire hyperactivity,Qi and blood deficiency.Most of them are liver kidney yin deficiency and liver depression and spleen deficiency.There is no significant correlation between the TCM syndrome differentiation and the AC / a value,BCC value,NRA value and pra value of patients with regulatory visual fatigue.
