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.
