66例水平斜视患者肌止端距离测量分析

Muscles in 72 Cases with Horizontal Strabismus with Only One Side of Distance Measurement

目的:评价水平斜视患者内直肌肌止端及外直肌肌止端距角膜缘距离是否为发病影响因素之一。方法:手术中测量66例水平斜视患者132条内、外直肌肌止端距角膜缘距离,并进行统计分析后与正常人群比较是否具有差异性。结果:测量组内直肌66条,距离(4-7)mm,平均(5.3±0.6)mm,正常参考值为5.5mm,二者间差异具有统计学意义(p<0.05)。测量外直肌66条,距离(4.5-10.50)mm,平均(6.6±0.8)mm,正常参考值为6.9mm,二者间差异具有统计学意义(p<0.05)。结论:内、外直肌肌止端距角膜缘距离可能为水平斜视的发病影响因素之一。

Objective：To discuss whether the factor of the distance inserted from internal rectus muscle and lateralrectus to limbus cornea could influence the incidence of horizontal strabismus.Methods：the distances inserted from internal rectus muscle and from that of lateralrectus to limbus cornea in 66 patients with horizontal strabismus（66 medialrectus and 66 lateralrectus） were measured,and the results were compared with the health adults statistically.Results：In patients with horizontal strabismus,the mean distances inserted from internal rectus muscle and from that of lateralrectus to limbus cornea were 5.3±0.6mm（range from 4-7mm） and 6.6±0.8mm（ranging from 4.5-10.5mm）,respectively,and in health adults,the mentioned-above data were 5.5mm and 6.9mm,respectively.There were significant observed differences between horizontal strabismus patients and health adults.Conclusion：The distance inserted from internal rectus muscle and from that of lateralrectus to limbus cornea may influence the incidence of horizontal strabismus.
