目的:探讨硅油填充原因及硅油填充时间与相关并发症的关系。方法:回顾分析总结66例70只硅油填充眼的临床资料及随访记录。结果:硅油填充的主要原因为常规孔源性视网膜脱离反复多次手术操作,其次是黄斑裂孔性视网膜脱离,再次为增生性糖尿病性视网膜病变。硅油平均填充时间10.5mo,硅油乳化发生率28.6%,高眼压发生率15.7%,角膜变性发生率2.9%,严重白内障的发生率46%。硅油取出后主要并发症是视网膜脱离复发。结论:在定期随访的情况下,可适当延长硅油在眼内的存留时间。取硅油时,保持玻璃体腔持续灌注,并根据视网膜情况行视网膜激光、眼内气体充填或再次行硅油填充等处理,可以减少硅油取出术后并发症的发生。

AIM:To investigate the relationship between duration silicone oil temponade and complication and the cause of silicone oil temponade.METHODS:Retrospective survey was done in 66 cases (70 eyes) of silicone oil temponade.RESULTS:The primary cause of silicone oil temponade was regular hole retinal detachment,the second was retinal detachment with macula hole,the third was proliferative diabetic retinopathy. The average time of silicone oil temponade was 10.5 months,the incident rate of silicone oil emulsification was 28.6%,the incident rate of ocular hypertension was 15.7%,corneal degeneration was 2.9%,severely cataract was 46%. The main complica-tion of silicone oil removal was recurrence retinal detach-ment.CONCLUSION:In the follow-up on a regular basis,we can appropriately extent the remaining time of intraocular silicone oil. When silicone oil is removed,to maintain the vitreous cavity infusion,and according to the retinal situation to choose retinal laser,intraocular gas filling or silicone oil tamponade can reduce the occurrence of postoperative complications.
