• Pars plana vitrectomies were performed on 85 diabetic eyes with preoperative posterior retinal holes. Six months following vitrectomy, 27 of the eyes had substantial visual improvement. Additional retinal holes were a frequent operative complication, occurring in 35 (41%) of the eyes. Of those postvitrectomy irides that could be visualized, 25 had rubeosis involving the peripheral iris or angle. Neovascular glaucoma occurred during the follow-up period in 18 eyes. The vitreous cavities were clear in 53 eyes, and the macula was attached in 47 (55%) of the eyes, but opacities of more anterior structures prevented visualization of the fundi in many cases.
