目的 :探讨增殖性糖尿病视网膜病变 (proliferativediabeticretinopathy ,PDR)玻璃体视网膜手术后严重玻璃体出血的原因、并发症及处理方法。方法 :对我院 1997年 1月至 2 0 0 1年 3月住院行玻璃体视网膜手术治疗PDR的 182例 (198只眼 )患者中术后发生严重玻璃体出血的 16例 (17只眼 )患者进行回顾性分析。结果 :术后玻璃体出血中 5 2 9%出现于术后第一天 ,出血原因包括纤维血管膜残端出血、视网膜新生血管膜渗血、视网膜切开、视网膜裂孔、前玻璃体纤维血管增殖等 ;出血并发症包括继发性青光眼、增殖膜形成等。结论 :PDR玻璃体切割术后玻璃体出血为术后常见的并发症 ;对于出血量大、难于吸收及出现并发症的病例 ,积极治疗可改善视力预后
Objective: To investigate the causes, complications and treatment of severe vitreous hemorrhage after proliferative diabetic retinopathy (PDR). Methods: A total of 16 patients (17 eyes) with postoperative severe vitreous hemorrhage were enrolled in 182 patients (198 eyes) with vitreoretinal surgery undergoing vitreoretinal surgery in our hospital from January 1997 to March 2001. Retrospective analysis. Results: 529% of postoperative vitreous hemorrhage occurred on the first postoperative day. The causes of hemorrhage included hemorrhage of fibrovascular stump, retinal neovascularization, retinal detachment, retinal tears and previtreous fibroblast proliferation. Bleeding complications include secondary glaucoma, proliferative membrane formation and the like. Conclusion: Vitreous hemorrhage after PDR vitrectomy is a common postoperative complication. For patients with large amount of bleeding, difficult to absorb and complications, active treatment can improve visual outcome
