[Late results of pars plana vitrectomy in diabetics (author's transl)]

Report on 82 consecutive cases in which pars plana vitrectomy was performed because of intravitreal hemorrhage. Postoperative follow-up ranged from 3 to 4 1/2 years. Although an incipient improvement of the visual acuity was achieved in 54%, recurrent hemorrhages as well as progression of the proliferative diabetic retinopathy lead to visual deterioration of blindness in 64% of the eyes.
