玻璃体切除术治疗后段眼内异物及视网膜脱离

目的探讨玻璃体切除术治疗眼后段眼内异物及视网膜脱离的效果。方法常规平坦部三切口闭合式玻璃体切除术联合眼内异物摘出、视网膜复位、眼内光凝、眼内注入C3F8及硅油眼内填充等多联手术。结果26例（26眼）眼内异物全部一次摘出成功及视网膜脱离完全复位22眼，占84．62％，19眼视力均有不同程度的提高。其中，2眼视力0．5，1眼视力0.6。结论眼后段眼内异物合并视网膜脱离，选择玻璃体手术具有直观、准确、安全、组织损伤小、异物摘出率高及去除外伤性玻璃体视网膜增生等优点。

Vitrectomy for posterior segment intraocular foreign bodies and retinal detachment

Objective To investigate the efficiency of vitrectomy for posterior segment intraocular foreign bodies and retinal detachment. Methods Three incision vitrectomy with intraocular foreign bodies extraction and retinal reattachment,endophotocoagulation,C_3F_8 intraocular injection and silicone oil tamponade,et al. Results Intraocular foreign bodies were extracted by one time in 26 cases,among them 84.59% patients had complete retinal reattachment in 22 cases.Different visual acuity improved in 19 cases,up to 0.5 in 2 cases and to 0.6 in one case. Conclusions Vitrectomy for posterior segment intraocular foreign bodies combining with retinal detachment has many advantages:accurate,safety,less injury,high extraction rate and avoiding traumatic proliferative vitreoretinopathy,et al.
