玻璃体切割术治疗眼内异物的疗效观察

Vitrectomy for intraocular foreign body

目的 评价并比较玻璃体切割术与外路异物吸出术治疗眼内异物的效果。方法 对眼后节异物患者 91例 97眼进行回顾性分析 ,其中行玻璃体切割异物摘出术 6 0只眼 ,行外路异物吸出术 37只眼。结果 外路异物吸出术异物摘出率为 70 3% ,术前、术后视力变化无显著性差异 (P >0 0 5 ) ;玻璃体切割异物摘出术异物摘出率为 10 0 % ,术后视力较术前有明显提高 (P <0 0 1)。玻璃体切割术后并发症少于外路异物吸出手术。结论 玻璃体切割术是治疗眼内异物的有效方法 ;对于非磁性异物 ,异物着床于视网膜或位于后部玻璃体腔内 ,伴有较重玻璃体积血或增殖的病例 ,玻璃体切割异物摘出术较外路异物吸出术更有利于摘出眼内异物和提高术后视力 ,解决异物存留的并发症。

Objective To evaluated the effects of magnetic extraction and vitrectomy extraction for posterior segment foreign bodies.Methods A retrospective research was done on 91 patients (97 eyes) in which 37 eyes have undergone magnetic extraction and 70 eyes have undergone vitrectomy extraction.Results Postoperatively,the successful rate of the extraction of foreign bodies in magnetic extraction group is 70 3%,and there is no significance between pro and post operation visual acuity ( P >0 05).Otherwise, in vitrectomy group,the successful rate of foreign bodies extraction is 100%,and the post operative visual acuity is much better than that of pro operation ( P <0 01).The complications of vitrectomy is less than magnetic extraction.Conclusions Vitrectomy is more favorable than magnetic extraction for the extraction of foreign bodies embedded in retina or posterior vitrous cavity、nonmagnetic foreign bodies,and the severe vitrous hemorrhage or proliferation.Vitrectomy is better for postoperative vision and the management of complications.
