目的:探讨玻璃体切除和硅油填充手术后视网膜再脱离的治疗。方法:回顾总结增殖性玻璃体视网膜病变(proliferative vitreorinapthy PVR)5例5只眼和外伤性PVR 3例3只眼的视网膜脱离手术后再脱离的治疗效果。治疗方法为经睫状体平坦部闭合式玻璃体切除、膜剥离、视网膜切开、内排液、硅油填充,2只眼加视网膜下膜膜剥离取出。结果:术后视网膜解剖复位6只眼,2只眼下方仍有浅脱离,术后视力提高6只眼,不变2只眼。结论:视网膜再脱离的原因与增殖性视网膜前膜和下膜形成有关,治疗原则为玻璃体切除、解除增殖膜的牵引和充分地液/油交换。
Objective: To investigate the treatment of retinal detachment after vitrectomy and silicone oil-filled surgery. Methods: The curative effect of retinal detachment after retinal detachment in 5 eyes of proliferative vitreoretinal PVR and 3 eyes of 3 eyes of traumatic PVR was retrospectively reviewed. Treatment for the ciliary body flat closed vitrectomy, membrane stripping, retinal incision, internal drainage, silicone oil filled, 2 eyes plus subretinal membrane stripping removed. Results: There were 6 eyes underwent retinal reattachment after operation. There was still a slight detachment below the two eyes. The postoperative visual acuity improved in 6 eyes and unchanged in 2 eyes. CONCLUSIONS: Reasons for re-detachment of the retina are related to the formation of a proliferative pre-retinal and sub-membranous membrane. The principle of treatment is vitrectomy, lifting of the proliferating membrane and adequate fluid / oil exchange.
