title: [Vitrectomy for treatment of ocular complications in diabetes. III. Factors influencing results of vitrectomy].
abstract: The aim of this study was to find factors influencing results of pars plana vitrectomy for proliferative diabetic retinopathy.
  
  
  METHODS
  25 general and local factors which could influence results of pars plana vitrectomy (ppV) were selected and compared with functional results of surgery of 168 eyes with diabetic retinopathy.
  
  
  RESULTS
  The most significant general factor was the age during ppV and the age at diagnosis of diabetes. Glycosylated hemoglobin blood level had little influence on ppV results. The most important local factor was the morphological state of the retina before the surgery. Better functional results were also achieved in eyes treated with panretinal photocoagulation before ppV and treated with vitrectomy without silicone oil tamponade when visual acuity was better than 5/50.
  
  
  CONCLUSIONS
  General state of patients before ppV has little influence on functional results of ppV. Local factors are the main factors influencing this results.
