眼外伤玻切气体充填后视网膜动脉阻塞的分析

Analysis of retinal artery occlusion after vitrectomy with gas tamponade in cases of ocular trauma

目的分析玻璃体切除联合注气术后发生视网膜动脉阻塞的原因。方法眼外伤7例(7眼)均行玻璃体切除联合注入C3F8。术后观察视力、视野、眼压、前房反应及眼底。结果术后眼压2例较低,5例正常;7例术后发生视网膜动脉分枝阻塞6例及中央动脉阻塞1例。结论玻璃体切除联合注入C3F8后发生视网膜动脉阻塞的原因是多方面的。

Objective To evaluate the cause of retinal artery occlusion after vltrectomy with C3F8 gas tamponade in ocular trauma patients. Methods Seven cases （7 eyes） of ocular trauma were treated with vltrectomy with C3F8 gas tamponade. The postoperative vision, visual field, IOP, anterior chamber inflammation and fundus were observed. Results The postoperative IOP were normal in 5 eyes, and postoperative IOP lowered in 2 eyes. All 7 eyes had occurred retinal artery occlusion after vitrectomy combined with C3F8 gas tamponade. Among them, 6 eyes had occurred branch retinal artery occlusion and 1 eyes occurred central retinal artery occlusion. Conclusion There are different causes of retinal artery occlusion after vitrectomy with C3F8 gas tamponade in ocular trauma patients.
