The results of primary vitrectomy for the complications of proliferative diabetic retinopathy were explored in 131 eyes of 105 patients. A minimum of 6 months' follow-up was obtained. The primary indications for surgery were persistent vitreous hemorrhage (in 66% of the eyes) and progressive tractional macular detachment (in 31%). Technical (surgical) success (clearing of the ocular media or relief of macular traction, or both) was achieved by the time of the last examination in 69% of the eyes; it was achieved in 70% of those with persistent vitreous hemorrhage and in 68% of those with tractional macular detachment. Visual improvement was observed in 55% of all the eyes.
对105例患者的131只眼睛进行了原发性玻璃体切除术治疗增生性糖尿病视网膜病变并发症的研究。获得了至少6个月的随访结果。手术的主要指征为持续性玻璃体出血（占66%的眼睛）和进行性牵拉性黄斑脱离（占31%）。在最后一次检查时，69%的眼睛实现了技术（手术）成功（清除眼内介质或缓解黄斑牵拉，或两者兼具）；持续性玻璃体出血的眼睛中有70%实现了技术成功，牵拉性黄斑脱离的眼睛中有68%实现了技术成功。所有眼睛中有55%观察到视力改善。
