探讨64排螺旋CT定位下眼球内磁性异物摘出的临床效果。 方法：对48例48眼眼球内磁性异物患者进行回顾性分析。其中32例巩膜探查摘出异物后，24例再行白内障超声乳化并人工晶状体植入术，8例行玻璃体切割，摘出异物的同时清除玻璃体积血或积脓。 结果：一期异物全部摘出。术后视力全部不同程度地提高。 结论：64排螺旋CT定位下眼球内磁性异物摘出是眼球内异物摘出的一种有效方法

To evaluate the clinical effect of 64 spiral CT localization method in extracting magnetic intraocular foreign body. METHODS:Fourty-eight cases (48 eyes) with 64 spiral CT intraocular foreign bodies were analyzed retrospectively,including 32 cases of intraocular foreign body extraction,of which 24 cases were performed phacoemulsification and intraocular lens implantation,and 8 cases of vitrectomy for extraction of foreign bodies and removal of blood or vitreous empyema at the same time. RESULTS: Magnetic intraocular foreign bodies were extracted by 64 spiral CT localization method completely in all eyes.The postoperative visual acuity of the patients all had varing degrees of rise. CONCLUSION: 64 spiral CT localization method is a smiple and effective method for extracting magnetic intraocular foreign body.
