Objective To observe the changes of binocular vision function in comitant strabismus patients before and after surgery.Methods 37 patients with constant comitant strabismus were involved in the study.The simultaneous perception and fusion were examed by synotophore and the stereacuity was examed by Shaoming Yan's stereogram.The patients who have ametropia must wear rectified glasses when examing.Record above examination datas before surgery and one month,three months,six months after surgery.The patients were divided into two groups,16 cases in the≤9 years of age group and 21cases in the9 years of age group.This study based on these datas.Results(1)Preoperative:The differences had statistical significance in the operation age and course(P0.05),no statistical significance in the onset age,the degree of deviation,simultaneous perception,fusion and range of fusion,stereacuity(P0.05).(2)Postoperative:Comparation between the two groups,the differences had statistical significance in the simultaneous perception at one month,three months,six months after surgery(P0.05).At one month after surgery the differences had no statistical significance in the fusion and range of fusion(P0.05);At three months and six months after surgery the differences had statistical significance in the fusion and range of fusion(P0.05).The differences had no statistical significance in the stereacuity at one month and three months after surgery(P0.05);The differences had statistical significance in the stereacuity at six months after surgery(P0.05).37 cases after surgery compared with before surgery,the difference had statistical significance in the simultaneous perception at one month after surgery(P0.05),no statistical significance in the fusion and range of fusion,stereacuity(P0.05);The differences had statistical significance in the simultaneous perception,fusion and range of fusion,stereacuity at three months and six months after surgery(P0.05).Cases in the 9 years of age group after surgery compared with before surgery: The differences had no statistical significance in the function of vision at one month and three months after surgery(P0.05);The differences had statistical significance in the range of fusion at six months after surgery(P0.05),no statistical significance in the simultaneous perception and stereacuity at six months after surgery(P0.05).Conclusion ①According to the recovery and rebuilding of binocular vision function,the operation for patients with comitant strabismus should be taken before 9 years old.②Active treatment also should be taken for the patients whose binocular vision function have matured.They also can get some extent recovery and rebuilding of binocular vision function.③Patients with constant comitant strabismus in China have older operation age and longer course.It should be necessary to enhance science education publicize,enlarge extensive survey of strabismus and amblyopia nationally,and make early detection,early diagnosis,early treatment as far as possible.
