【摘要】：目的：以虹膜定位技术为客观定量检查方法,结合临床观察斜视患者手术前、后眼球的客观旋转状态,探讨其在手术中的作用和意义,为手术改善和完善、测量标准提供新的依据。方法：收集本院2009年10月～2011年01月收入院的共同性外斜视、上斜肌麻痹的患者各40例,并随机分为显微手术组、非显微手术组,使用WaveScan波前像差仪取坐位行虹膜识别,获得虹膜图像和数据,使用美国威视公司VISX Star S4-IR准分子激光系统行仰卧位定位,记录术前、术后虹膜(眼球)旋转的角度。结果：主斜眼、主视眼手术前、手术后眼球的旋转度进行配对t检验,主斜眼、主视眼的非显微手术组与显微手术组进行两样本t检验。①共同性外斜视非显微手术组：主视眼手术前、手术后眼球旋转度分别为(4.88±2.55)。、(4.76±2.62)°,差别无统计学意义。主斜眼手术前、手术后眼球旋转度分别为(2.70±2.36)°、(6.00±2.76)°,差别有统计学意义。显微手术组：主视眼手术前、手术后眼球旋转度分别为(2.86±2.28)。、(3.12±2.17)°,差别无统计学意义。主斜眼手术前、手术后眼球旋转度分别为(2.08±1.86)°、(3.28±2.04)°,差别有统计学意义。主斜眼非显微手术组与显微手术组进行两样本t检验,术前差异无统计学意义,术后差异有统计学意义。②上斜肌麻痹非显微手术组：主视眼手术前、手术后眼球旋转度分别为(2.88±3.58)。、(2.08±2.36)。,差别无统计学意义。主斜眼手术前、手术后眼球旋转度分别为(2.48±2.51)°、(5.73±1.98)。,差别有统计学意义。显微手术组：主视眼手术前、手术后眼球旋转度分别为(4.90±3.60)°、(4.56±1.12)°,差别无统计学意义。主斜眼手术前、手术后眼球旋转度分别为(3.12±3.07)。、(4.26±1.98)°,差别有统计学意义。主斜眼非显微手术组与显微手术组进行两样本t检验,术前两组差异无统计学意义,术后两组差异有统计学意义。结论：①显微手术可以提高斜视手术的精细度。②虹膜定位技术可以客观地描述斜视患者的眼球旋转状态,减少手术源性旋转,并且为临床手术效果做出评价。
[Abstract]:Objective: to investigate the role and significance of the objective rotation of the eyeball in strabismus patients before and after operation by using the iris localization technique as the objective quantitative examination method, so as to improve and perfect the operation. The measurement standard provides a new basis. Methods: 40 patients with concomitant exotropia and superior oblique palsy were collected from October 2009 to January 2011. They were randomly divided into two groups: microsurgical group and non-microsurgical group. The sitting position of iris was identified by WaveScan wavefront aberration instrument. The iris images and data were obtained, and the position of supine position was located by VISX Star S4-IR excimer laser system. The angle of iris rotation was recorded before and after operation. Results: the rotation of the eye before and after the operation was tested by paired t test. Two samples were tested in the non-microsurgical group and the microsurgical group. 1 in the concomitant exotropia non-microsurgery group, the degree of ocular rotation was (4.88 卤2.55)., (4.76 卤2.62) 掳before and after the operation, respectively. The difference was not statistically significant. The degree of ocular rotation was (2.70 卤2.36) 掳and (6.00 卤2.76) 掳before and after the operation respectively, and the difference was statistically significant. In the microsurgery group, the degree of ocular rotation was (2.86 卤2.28)., (3.12 卤2.17) 掳before and after the operation, and there was no significant difference between the two groups. The degree of ocular rotation was (2.08 卤1.86) 掳and (3.28 卤2.04) 掳before and after the operation respectively, and the difference was statistically significant. T test of two samples was performed in the main oblique non-microsurgical group and the microsurgical group. There was no significant difference before operation, but there was significant difference after operation. There was no significant difference in the degree of ocular rotation (2.88 卤3.58)., (, 2.08 卤2.36).,) after operation. Before and after operation, the degree of ocular rotation was (2.48 卤2.51) 掳and (5.73 卤1.98)., respectively. In the microsurgery group, the degree of ocular rotation was (4.90 卤3.60) 掳and (4.56 卤1.12) 掳before and after the operation, respectively, and there was no significant difference. Before and after operation, the degree of ocular rotation was (3.12 卤3.07)., (卤4.26 卤1.98) 掳, and the difference was statistically significant. There was no significant difference between the two groups before operation, but there was statistical difference between the two groups after operation. Conclusion: 1 microsurgery can improve the fineness of strabismus surgery. 2 iris localization technique can objectively describe the state of eye rotation of strabismus patients, reduce the operative origin rotation, and evaluate the effect of clinical operation.
