硅油下视网膜复位术疗效探讨

目的 总结硅油填充术后视网膜再脱离行硅油正视网膜复位术的疗效,探讨该手术的适应证及手术技巧。方法 对１７例（１７只眼）硅油填充术后视网膜再脱离者,在保留硅油的条件下,做睫状体扁平部３切口,在导光纤维的导引下行剥膜、断膜、视网膜切开、内放液、内激光光凝、视网膜下全氟化碳液体取出、补充硅油等使视网膜得位。结果 １７只眼中,术后视网膜重位１４只眼,成功率为８２．４％。术中硅油误入前房１只眼,误入脉络膜上

A study of vitrectomy for retinal redetachment with silicone oil retained

Objective To evaluate the outcome of vitrectomy for retinal redetachment in eyes with silicone oil tamponade and investigate the indications and surgical techniques of this surgery Methods A total of 17 eyes (17 cases), in which retinal redetachment developed after the management of silicone oil tamponade, underwent pars plana vitrectomy with silicone oil retained Directed by endoilluminator, membrane peeling, membrane inside cut, full thickness retinal incision, internal drainage, endolaser, removal of subretinal perfluorocarbon liquids and injection of additional silicone oil, etc were performed to make retinal reattachment Results 14 eyes achieved retinal reattachment in total 17 eyes (82 4%) During operation, silicone oil migrated into anterior chamber in 1 eye and into suprachoroidal space in 1 eye There was 1 eye with vitreous hemorrhage and ocular hypertension postoperatively Retinal reattachment was not achieved in 3 eyes Conclusions Vitrectomy with silicone oil retained is an effective management for retinal redetachment of eyes with silicone oil tamponade The advantages of this method are economical and time saving But the surgeon should be well trained and competent with vitrectomy
