139例硅油取出术临床分析

目的 探讨硅油取出术的临床应用和手术风险控制方法。方法 对139例（139眼）玻璃体切除术联合硅油充填患者行主动持续负压吸引硅油取出术，观察术后患眼玻璃体腔和视网膜情况，分析术后眼压控制与视网膜再脱离的关系。结果 139例患者均顺利完成手术，其中135例（97.12%）术后玻璃体腔清、视网膜保持复位，4例（2.88%）术后发生视网膜再脱离；32例（23.02%）术后发生低眼压，其中4例术后发生视网膜再脱离患者术后均发生低眼压，28例术后未发生视网膜再脱离患者术后发生低眼压，低眼压发生率比较差异有统计学意义（100% vs 20.74%,χ2=13.77，P<0.01）。结论 主动持续负压吸引硅油取出术安全、可靠，术中和术后适当的眼压维持是硅油取出术成功的重要因素。

Clinical analysis of 139 cases of intraocular silicon oil removal

Objective To explore the clinical application and control of risks of operation in intraocular silicon oil removal.Methods Intraocular silicon oil removal with active and continuous aspiration were performed on 139 patients(139 eyes) who had received vitrectomy combined with silicon oil tamponade.The status of vitreous chamber and retina after operation was observed,and the relationship between intraocular pressure control and retinal redetachment after operation was analysed.Results All patients completed the operation.One hundred and thirty-five patients(97.12%) had clear vitreous chamber and intact retina after operation,while the other 4 patients(2.88%) experienced retinal redetachment after operation.Thirty-two patients(23.02%) developed lower intraocular pressure after operation,4 of whom were those with retinal redetachment after operation,and there were significant differences in the prevalences of lower intraocular pressure after operation between patients with retinal detachment after operation and those without retinal detachment after operation(100% vs 20.74%,χ2=13.77,P<0.01).Conclusion Intraocular silicon oil removal with active and continuous aspiration is safe and effective,and proper management of intraocular pressure during and after operation plays an important role in silicon oil removal.
