视网膜脱离硅油填充取出后疗效的分析

目的　探讨硅油取出的时机、方法及硅油取出能否防止并发症。方法　分析20 例由于严重并发症的出现而施行硅油取出术的病人,平均取出时间为14.7 月。结果　20 只眼取硅油。2 眼为注硅油后视网膜脱离复发,取硅油后1 眼再施视网膜脱离复位术后视网膜平复,1 眼未再手术。2 眼硅油取出后发生视网膜脱离,余16 眼取硅油后视网膜仍在位。结论　硅油取出是治疗硅油注入术后并发症的有效措施,但视网膜脱离术后不宜早期取出全部硅油。视网膜裂孔和增殖性玻璃体视网膜病变(PVR)的完善处理及术后不要早期取硅油是降低视网膜脱离复发的关键。硅油取出时机为稳定的视网膜复位后或出现硅油注入并发症时

The effects of silicone oil removal in the treatment of retinal detachment

Objective To discuss when and how to remove intraocular silicone oil which was used in treatment of retinal detachment and whether silicone oil removal can preclude its complications.Methods Results of silicone oil removal because of complications in 12 eyes were analysied.The mean duration of oil tamponade was 14.7 months.Results Eye developed retinal reattachement after performing cryotherapy and reinjecting silicone oil.The other eye suffered retinal detachment because of severe proliferative vitreoretinopathy(PVR).1 eye was found retinal detachment after the procedure of silicone oil removal.So in 17 of 20 eyes,the retinae were still attached after silicone oil removal.Conclusions Silicone oil removal is an effective procedure in the management of ocular hypertension,but it's not wise to remove retinal detachment,it is important to treat retinal breaks and PVR perfectly and not to perform early removal of silicone oil postoperatively.Silicone oil removal should be performed only when the retina gets reattached steadily and complications occurs.
