目的 讨论眼内铜异物的定位方法和摘出术式以提高成功率。方法 金属环X线正、侧、轴位片及薄骨正、侧位片 ;微小铜异物加摄无骨 ,钼靶软X线片 ;必要时作巩膜面“H”型金属标记摄片 ;在手术显微镜直视下分别采用角膜缘切口 ,平坦部切口 ,巩膜视网膜切口 ,以及联合闭合式玻璃体切除术。结果 手术成功率 10 0 % ,术中、术后无严重并发症 ,视力都有提高。结论 眼内铜异物在准确定位的前提下 ,需在手术显微镜直视下摘出 ;对眼后段铜异物的摘出 ,须联合玻璃体切除术。
Objective To discuss the method of locating copper intraocular foreign bodies and the method of extracting them to improve the success rate. Methods Metal ring X-ray is positive, side, axial and thin bone is positive, lateral slices; fine copper foreign body plus bone-free, mammography soft X-ray film; if necessary, for scleral surface “H” Operative under the microscope were used limbal incision, flat incision, scleral retinal incision, and combined closed vitrectomy. Results The success rate of surgery was 100%. There was no serious complications during and after surgery, and visual acuity improved. Conclusion Intraocular copper foreign body in the accurate positioning of the premise, need to be removed under direct microscope surgery; removal of the posterior segment of the copper foreign body, to be combined with vitrectomy.
