title: [Is the prognosis of pars plana vitrectomy in diabetic retinopathy dependent on the general status of the diabetic?].
abstract: Results of pars plana vitrectomy (PPV) were compared in two groups of patients. The first group was formed from 105 eyes of 87 diabetics without clinical signs of the diabetic nephropathy or nephropathy without decrease of renal functions. The other group was formed from 64 eyes of 50 diabetics suffering from diabetic nephropathy in the stage of the renal insufficiency. In the first group PPV was successful during the mean observatory period of 26 months, in 59 from 105 eyes (56%) and the mean visual acuity was 0.12. In the second group PPV was successful, during the mean observatory period of 18 months, in 34 from 64 eyes (53%) and the mean visual acuity was 0.09. Number of the successfully treated PPV was steadily decreasing according to the prolonged period of the further observations, in both mentioned groups: from 85 (81%) after 3 months on 62 (41%) after the interval of 3 years. The mean visual acuity in both followed groups was, with respect to the length of observation, moderately increased. Diabetic nephropathy in the stage of the renal insufficiency was without negative effect on the prognosis of PPV in complicated diabetic retinopathy. The more advanced organ complications of diabetes were not evaluated as contraindications of PPV and the operation may significantly improve the quality of the life of an otherwise heavily ill diabetic patient.
