眼内异物临床较为常见。常规X线检查对金属异物虽能较准确定位,但对于直径较小的异物及位于球壁界面上的异物要准确诊断仍有很大的局限性。CT检查能清晰观察眼内组织结构及轮廓,对异物有很高的分辨率,故对眼内较小异物的诊断和球壁界面异物的观察有较高的鉴别能力。现就我院1992年～1994年30例眼内异物的CT检查作一分析,以探讨其对眼内异物的诊断价值。
Intraocular foreign body is more common clinical. Routine X-ray examination of metal foreign body can be more accurate positioning, but for the smaller diameter of the foreign body and located in the ball-wall interface to accurately diagnose there are still great limitations. CT examination can clearly observe the structure and contour of the intraocular tissue, foreign body has a high resolution, so the smaller foreign body in the diagnosis of foreign body ball ball interface and the observation of foreign objects have a higher ability to identify. Now on our hospital from 1992 to 1994 30 cases of intraocular foreign body CT examination for an analysis to explore its diagnostic value of intraocular foreign body.
