Pars plana vitrectomy was used to treat 134 consecutive eyes with complications resulting from proliferative diabetic retinopathy, including nonabsorbing vitreous hemorrhage, recent traction and rhegmatogenous retinal detachment, progressive fibrovascular proliferation, and early rubeosis iridis with recent vitreous hemorrhage. Vision improved after surgery in 65% of the eyes, was unchanged in 16%, and decreased after surgery in 19%. In 24% of the successful cases, vision of 20/50 or better was achieved. When all posterior cortical vitreous was removed, no preretinal fibrovascular growth occurred after surgery. Nonatrophic epiretinal fibrovascular membranes that were not removed usually underwent centripetal contraction after surgery, causing tangential traction on the adjacent retina. Rubeosis iridis was the most common postoperative complication in otherwise successful cases, and rubeosis underwent regression after scatter retinal photocoagulation in some eyes.
采用玻璃体切除术治疗134例因增殖性糖尿病视网膜病变导致并发症的连续病例，这些并发症包括不吸收性玻璃体出血、近期牵拉性和孔源性视网膜脱离、进行性纤维血管增殖以及伴有近期玻璃体出血的早期虹膜新生血管。术后65%的患眼视力提高，16%的患眼视力无变化，19%的患眼术后视力下降。在24%的成功病例中，视力达到或优于20/50。当全部切除后皮质玻璃体时，术后未发生视网膜前纤维血管生长。未切除的非萎缩性视网膜前纤维血管膜术后通常向心性收缩，对相邻视网膜产生切线牵拉。虹膜新生血管是其他方面成功的病例中最常见的术后并发症，部分患眼在视网膜光凝术后虹膜新生血管消退。
