Factors Influencing The Development Of Binocular Visual Function In Children With Refractive Error And Anisometropic Amblyopia

Objective:To observe the development of binocular visual function and its influencing factors in patients with intermittent exotropia.Methods:Selection of intermittent exotropia patients 131 cases,depending on the machine with measured at the same time,integration function,far stereopsis,according to the exist,does not exist,respectively for"yes"and"no",YanShaoMing stereo vision figure nearly stereo vision,nearly stereo vision points"yes"(?800")or less,"no"(>800"),records of all patients at the same time,the fusion function and far and near stereoscopic"yes"and"no"cases,statistics with the onset age,type of strabismus,strabismus degree and control the degree of relationship.Among them,a total of 91patients with positive eye position were followed up for at least 6 months during the orthopedics of strabismus,with simultaneous vision,fusion function,distal stereoscopic vision and near stereoscopic vision recorded,and the number of cases with"recovery"and"no recovery"compared with those before surgery were recorded,and the relationship between the age of operation,strabismus type,strabismus degree and degree of control were calculated.Results:1.Factors affecting the development of binocular visual function in intermittent exotropia:(1)at the same time,vision was related to the degree of control of patients(x~2=4.061,P<0.05),and had no correlation with age of onset,type of strabismus,and degree of strabismus(x~2=0.089,0.343,3.718,P>0.05).(2)fusion function was related to the degree of control of patients(x~2=4.122,P<0.05),but was not related to the age of onset,strabismus type,and strabismus degree(x~2=0.038,0.550,3.605,P>0.05).(3)fusion function was related to the degree of control of patients(x~2=5.029,P<0.05),but was not related to the age of onset,strabismus type,and strabismus degree(x~2=0.011,0.579,2.865,P>0.05).(4)the close stereoscopic vision was related to the degree of control of the patient(x~2=9.511,P<0.05),and had no correlation with the age of onset,strabismus type,and strabismus degree(x~2=0.617,0.615,3.658,P>0.05).2.Influence of surgery on intermittent exotropia and related factors: postoperative simultaneous visual function,fusion function,stereopsis and stereopsia were better than those before surgery,with statistically significant differences(x~2=21.162,17.283,15.534,9.192,P< 0.05).(1)factors affecting simultaneous visual recovery: simultaneous visual recovery was related to patients' surgical age and degree of control(x~2=12.438,9.999,P<0.05),but had no correlation with patients' strabismus type and degree of strabismus(x~2=1.953,1.417,P>0.05).(2)factors affecting the recovery of fusion function: the recovery of fusion function was correlated with the age of operation and the degree of control of patients(x~2=12.765,5.939,P<0.05),but not with the type of strabismus and the degree of strabismus(x~2=1.840,0.240,P>0.05).(3)factors affecting the recovery of stereoscopic vision: the recovery of stereoscopic vision was related to the age of operation and the degree of control of patients(x~2=10.155,5.283,P<0.05),but was not related to the type of strabismus and the degree of strabismus(x~2=0.183,1.354,P>0.05).(4)factors affecting the recovery of near-stereoscopic vision: the recovery of near-stereoscopic vision was related to the surgical age and degree of control of the patients(x~2=6.972,8.065,P<0.05),but had no correlation with the type and degree of strabismus of the patients(x~2=0.354,0.174,P >0.05).Conclusions:1.Control ability is an important factor affecting binocular visual function development in patients with intermittent exotropia.2.The younger the age of operation and the better the control force,the better the recovery of binocular visual function.3.Age and control ability can be used as factors for the timing of surgery.
