观察硅油在外伤性玻璃体视网膜手术中的作用。 方法：眼外伤患者36例36眼接受经睫状体扁平部玻璃体切除手术治疗，术中使用曲安奈德和激光，眼内填充硅油。术后8mo左右行硅油取出手术。 结果：硅油填充后，观察10mo。及时补充激光治疗。观察期内，视网膜平伏，未见眼内出血和严重增殖性反应，无感染性眼内炎。 结论：硅油在外伤性玻璃体视网膜手术中，可起到长期顶压视网膜，控制炎症反应，抑制增殖和预防感染的作用，并为术后及时补充激光治疗提供有利条件。

To observe clinical effect of silicone oil in traumatic vitreoretinal surgery. METHODS:The vitrectomy was performed on 36 cases (36 eyes) with ocular trauma from October 2009 to January 2011.Triamcinolone acetonide and laser were used during surgery and the eyes were filled with silicone oil . Silicone oil removal time was about 8 months after surgery. RESULTS: The observation period was 10 months. Laser treatment was added. In observation period, there were no retinal detachment, no intraocular hemorrhage and severe proliferative response, and no infectious endophthalmitis. CONCLUSION: Silicone oil in traumatic vitreoretinal surgery can support the retina for a long time, control inflammation, inhibit proliferation and play the role of infection prevention,and provide favorable conditions for timely added laser treatment.
