The Study About The Influencing Factors Of Myopia After Cure Of Hyperopic Amblyopia In Children

Objective: Through retrospective studies,this study explored the influencing factors of myopia after cure of hyperopic amblyopia in children,and reached relevant conclusions,guided clinically targeted prevention,and formulated effective preventive measures to prevent the development of myopia.Method: The data of the cured myopic children with amblyopia were retrospectively collected from the Department of Ophthalmology Clinic or Optometry Center of the First Affiliated Hospital of Guangxi University of Traditional Chinese Medicine between September 2015 and January 2018,including the results of the first consultation of ophthalmology related examinations.(age,vitreous cavity depth,axial length,hyperopic diopter,eye position,etc.),and re-diagnosis ophthalmological related examination results(open eye distance vision,intraocular pressure,anterior segment examination,fundus examination,etc.)and questionnaire contents(date of birth,whether the parents are nearsighted,treatment course of hyperopia amblyopia,whether they wear glasses during the treatment of amblyopia according to the doctor's advice,average daily eye time,average daily outdoor activity time,or live in rural or urban areas,etc.).A total of 100 cases(200 eyes)were collected,including 60 males(120 eyes)and 40 females(80 eyes).The age of the first diagnosis was 3-12 years(average age was 5.5 years).According to the examination results during the second consultation,the data were divided into the myopic group and the non-myopic group,including 23 cases(46 eyes)in the myopic group and 77 cases(154 eyes)in the non-myopic group.The retrospective analysis method was used to compare the age of two groups at the first visit,vitreous cavity depth,axial length,hyperopic diopters.Eye position,etc.,and sex,genetics,treatment course of hyperopia amblyopia,wearing glasses compliance,average daily close eye time,average daily outdoor activity time,and living in rural or urban areas.Data input and logic error detection were carried out with Microsoft Excel table,and all data were statistically analyzed by SPSS 20.0 statistical software.The counting data were expressed by frequency(percentage)and chi-square test was used,the measured data are skewed distribution,expressed as a median(quartile spacing),and non-parametric test was used.All variables were analyzed by single factor analysis and then by multivariate Logistic regression analysis.The results of the test(P<0.05)indicated that the difference of the data tested was statistically significant.Results: 1.The results of univariate analysis showed that at the level of a =0.05,first diagnosed age,heredity,first diagnosed hyperopia diopter,first eye position,complianc with glasses,myopia in rural areas or in urban and children with hyperopia amblyopia after cure Relevant,the difference was statistically significant(P<0.05);but there was no statistically significant difference in sex,first diagnosis of vitreous cavity depth,length of the first consultation axial length,treatment course of hyperopia amblyopia,average daily close-eye time,and average daily outdoor activity time.(P>0.05).2.After multivariate logistic regression analysis,the risk of myopia was higher in children aged 7-12 years than in children aged 3-6 years;the risk of nearsightedness was higher in children whose parents had myopia than in children without parents.The risk of nearsightedness in parents of a child with myopia is 0.3 times that of non-myopic parents(because the criterion for the removal of the model is 0.1,if the ?=0.05 level,this conclusion is not valid,so the variable is not selected).The first diagnosis of vitreous cavity in children with the longer,the higher the risk of myopia occurs;the first diagnosis of hyperopia higher the incidence of children with myopia,the lower the risk;the first diagnosis of patients with positive eye position myopia The risk was 0.202 times that of the first diagnosed person with phoria;the children with poor spectacles compliance had a higher risk of myopia than those with good spectacles compliance;the average risk of myopia was higher in children with an average daily outdoor activity.Low;the risk of myopia in children who live in cities is 5.766 times that of those who live in rural areas.Conclusion: 1.First diagnosed age,,heredity(both parents have myopia),depth of vitreous cavity at first visit,compliance with wearing mirror,home living in rural area or city were risk factors formyopia in children wityhhyperopia amblyopia cure Specifically,children aged 7-12 years at first visit had a higher risk of developing myopia than those aged 3-6 years;children with nearsightedness in my parents had a higher risk of myopia than those without parents.The longer the body cavity depth was,the higher the risk of myopia was.The children with poorly-wearing glasses had a higher risk of myopia than those with good glasses compliance.The children who lived in urban areas had a higher risk of myopia than those who lived in rural areas.2.The first diagnosis of hyperopia,first eye position,and average daily outdoor activity time were protective factors for myopia in children with hyperopia amblyopia.Specifically,the higher the presbyopic diopter,the lower the risk of myopia.The risk of nearsightedness is lower in the first diagnosis of the patient with hyperopic refraction than in the first diagnosis.The average daily outdoor activity is longer.In children,the risk of myopia is lower.
