The indications for vitrectomy in the management of proliferative diabetic retinopathy are increasing. This is due to the improving results associated with earlier surgery, improving instrumentation and refinements in technique. The current indications for surgery include chronic or recurrent vitreous haemorrhage (of at least one months duration), progressive extramacular tractional retinal detachment, tractional macular detachment and elevated proliferative diabetic retinopathy. This paper reviews a series of 30 vitrectomies performed for severe complications of proliferative diabetic retinopathy. Most favourable visual outcome was associated with surgery for chronic or recurrent vitreous haemorrhage (in the absence of rubeosis iridis) and progressive extramacular tractional retinal detachment. Poor visual prognostic factors were, pre-operative rubeosis iridis and tractional retinal detachments involving the macula.
玻璃体切除术在增殖性糖尿病视网膜病变治疗中的应用指征正在增加。这是由于早期手术带来的效果改善、器械的改进以及技术的完善。目前的手术指征包括慢性或复发性玻璃体出血（至少持续一个月）、进行性黄斑外牵拉性视网膜脱离、牵拉性黄斑脱离以及增殖性糖尿病视网膜病变进展期。本文回顾了30例因增殖性糖尿病视网膜病变严重并发症而进行的玻璃体切除术。最有利的视觉预后与慢性或复发性玻璃体出血（无虹膜红变）以及进行性黄斑外牵拉性视网膜脱离的手术相关。不良的视觉预后因素包括术前虹膜红变以及累及黄斑的牵拉性视网膜脱离。
