目的探讨开放性眼球伤后视网膜脱离手术方法、失败原因及预后。方法对31例（31只眼）开放性眼球伤后视网膜脱离进行手术治疗，8例行巩膜冷凝、巩膜扣带及环扎术。23例行三切口闭合式玻璃体切除术，同时联合巩膜扣带及环扎术，其中8例眼内充填硅油，8例充填16％C2F6，7例充填20％SF6。结果术后视网膜复位25例（80．6％），术后视力较术前提高19例（61．3％）。手术失败的主要原因是前部增殖性玻璃体视网膜变病和术中／术后眼内出血。结论术中前部玻璃体增殖膜残留及术后形成前部PVR是手术失败的主要原因，由于外伤眼形成的PVR术中难以清除干净，因此巩膜扣带术是必要的。眼球破裂伤较眼球穿通伤预后差。
Objective To investigate the methods, causes and prognosis of retinal detachment after open eyeball injury. Methods Thirty - one eyes (31 eyes) underwent open surgery for retinal detachment. Eight patients underwent scleral buckling and cerclage surgery. Twenty - three cases underwent three - incision closed vitrectomy combined with scleral buckling and cerclage. Among them, 8 eyes were filled with silicone oil, 8 cases were filled with 16% C2F6 and 7 cases were filled with 20% SF6. Results Postoperative retinal reattachment in 25 cases (80.6%), postoperative visual acuity increased 19% (61.3%) compared with preoperative. The main reasons for the failure of surgery are anterior proliferative vitreoretinopathy and intraoperative / postoperative intraocular haemorrhage. Conclusion The residual vitreous membrane in the anterior segment and the anterior PVR after the operation are the main reasons for the failure. Scleral buckling is necessary due to the difficulty of removing the PVR during trauma. Ocular rupture than the penetrating eye injury poor prognosis.
