在白内障超声乳化吸除联合人工晶状体植入术中，术前准确测量眼轴长度并计算植入的人工晶状体度数是非常关键的步骤，目前，术后的屈光误差主要来自于由术前眼轴测量误差引起的人工晶状体度数偏差[1-2]。

Collecting a total of 102 cases(107eyes) of pations with traumatic optic neuropathy that underwent edoscopic optic nerve decompression surgery during December 1999 - April 2008 line,retrospective analysis of CT performance for the optic canal and paranasal sinuses,and Comparison of them with surgical results.102 cases of patients performed routine and coronal axial sinus CT scans,the optic canal zone wi th thin target scan,line of nasal tip and the anterior clinoid process connection as baseline for axis scan,and the vertical line of "bed nasal line" as baseline for coronal scan.

方法收集1999年12月-2008年4月间在青医附院耳鼻喉科行鼻内镜下视神经减压手术的外伤性视神经病患者的病例，共102例(107眼)，回顾分析其鼻窦及视神经管CT表现，并查看手术记录描述，将CT结果与术中所见情况进行对比分析。102例患者术前常规行轴位及冠状位鼻窦CT扫描，视神经管区行薄层靶扫描，以骨性鼻尖与前床突的连线为轴位扫描基线，以&床鼻线&的垂直线为冠状位扫描基线。

Diopter, corneal curvature, depth of anterior chamber and the axial length of the eyes were measured. We calculated the concordance of hyperopia, intrapair correlation coefficient and heritability index of monozygous and dizygous twins.

调查了同卵和异卵双生子的屈光度、角膜曲率半径、前房深度、眼轴长度，计算了远视的一致率，同卵和异卵双生子的组内相关系数及遗传指数等项目，证实远视眼是一种多因子遗传病，它的发生除了与多个遗传性状如角膜曲率半径、前房深度、眼轴长度等有关外，还与环境因素有关。

RESULTS: After root canal preparation, the mean value of the angles of canal curvature decreased from 36.21° to 21.98°, while the mean value of the radius of the canal curvature increased from 6.25mm to 11.35mm; the canal axes transported and intercrossed with the original axes at 2 points and created 3 intersection zones.

结果：根管预备完毕，根管弯曲角度均值从预备前的36.21°逐渐减小至21.98°，弯曲半径均值从6.28mm增大至11.35mm；根管长轴发生了偏移，与预备前原根管长轴形成2个交点，3个相交区。
