目的:总结牵拉性视网膜脱离手术方法、失败原因和提出预防措施。方法:对30例牵拉性视网膜脱离的眼底改变和发病原因进行回顾性分析。结果:扣带手术8例,4例成功,4例失败者再做视网膜玻璃体(R-V)联合手术3例成功。22例复杂病例采用R-V联合手术,14例成功,手术成功率70%。结论:术后形成前部PVR是手术失败的主要原因。严重的眼穿通伤2周时应做玻璃体切割术,各种原因的玻璃体出血在3～6个月应考虑手术治疗,处理好眼外伤的伤口和内眼手术切口很有必要。 OBJECTIVE: To summarize the surgical methods, causes of failure and proposing preventive measures for retinal detachment. Methods: Retrospective analysis of 30 cases of retinal detachment retinal detachment and the causes of the disease were retrospectively analyzed. Results: Cingulate surgery in 8 cases, 4 cases were successful, 4 cases of losers to do retinal vitreous (R-V) surgery in 3 cases. Twenty-two complicated cases were treated with R-V combined surgery, 14 cases were successful, the success rate was 70%. Conclusion: The formation of anterior PVR after surgery is the main reason for the failure. Severe eye injury through 2 weeks should be done vitrectomy, vitreous hemorrhage of various reasons should be considered in 3 to 6 months surgical treatment of eye wounds and eye surgery incision is necessary.
