摘　　要：目的探讨螺旋CT在眼内异物定位测量中的应用。方法25例眼内异物患者于螺旋CT扫描后,采用作者总结的简单定位测量计算方法,得出异物到角膜缘的弧线距离。结果均经临床手术证实,定位数据准确。结论螺旋CT眼内异物定位法简单、实用、准确、直观,值得临床广泛应用。Objective To evaluate spiral CT in localizing and measuring intraocular foreign body. Methods 25 patients underwent spi- ral CT scan,a simple method that the authors developed was used to localize and measure the foreign body and to gain the distance of the arc from foreign body to corneal margin. Results The data gained from the localization method were proved to be accurate by operation. Conclusion The method of spiral CT localization of intraocular foreign body is simple, useful,accurate and worthy to be used extensively in clinic.
