硅油协助眼内异物取出的应用

目的 探讨在玻璃体切除术中利用硅油协助眼内异物取出和避免视网膜再次损伤的效果.方法 系列病例研究.对2007年6月至2008年4月收治的伴有视网膜损伤的17例眼内异物患者临床资料进行回顾性分析.在切除玻璃体和修复损伤的视网膜后,对不易夹取的眼内异物采用先注入硅油再取出异物的操作步骤,利用硅油的黏滞作用,协助异物取出并减少视网膜再次损伤.结果所有眼内异物在硅油的协助下均顺利取出,手术过程中未造成视网膜的再次损伤.结论对于难以稳定夹持的眼内异物,采用先注入硅油再取出异物的手术程序,有利于异物的取出并可减少取出过程中视网膜的再次损伤.(中华眼科杂志,2009,45:216-218)

The remove of intraocular foreign body by the assistance of the injection of silicone oil

Objeqtive To evaluate the effect of the injection of silicone oil in helping the remove of intraocular foreign body throughout pars plana vitrectomy(PPV).MethodsIt was a series case study.This study included 17 eyes with intraocular foreign body from June 2007 to April 2008.Intraocular foreign bodies in these eyes were hardly removed,and all of the eyes had complicated and severe retinal injuries.The intraocular foreign bodies were taken out followed intravitreal injection of silicon oil.The retinal protective effects of silicon oil were studied.Results All the intraocular foreign bodies were removed successfully without any damage to the retina due to the viscosity of silicon oil and its gasket function.Conclusions Intravitreal injection of silicon oil was able to help the removement of hardly-hold intraocular foreign body with PPV and avoid secondary retinal injury in this process.(Chin J Opthalmol,2009,45:216-218)
