Penetrating wounds of the orbit can have serious immediate and delayed effects on the eye and the CNS. Infection, vessel erosion, or interference with ocular function necessitates removal of the foreign object. Precise localization of the retained material and its relationship to the globe, extraocular muscles, optic nerve, and brain is essential, when surgery is contemplated. We describe two children with retained foreign bodies that required removal. Computed tomography (CT) was essential in one instance in planning the surgical approach. In the other patient, the retained foreign body and an associated brain abscess were recognized only by CT. The contribution of CT to the assessment of retained foreign bodies is discussed and its present limits are defined. Computed tomography is highly recommended as the single most informative diagnostic modality for this type of injury.
眼眶穿透伤可对眼睛和中枢神经系统产生严重的即时和延迟影响。感染、血管侵蚀或眼功能干扰需要取出异物。当考虑进行手术时，精确确定留存异物的位置及其与眼球、眼外肌、视神经和脑的关系至关重要。我们描述了两名需要取出留存异物的儿童。在其中一例中，计算机断层扫描（CT）对于规划手术入路至关重要。在另一例患者中，仅通过CT才识别出留存异物及相关脑脓肿。本文讨论了CT在评估留存异物方面的作用，并界定了其目前的局限性。强烈推荐将计算机断层扫描作为这类损伤最具信息量的单一诊断方式。
