title: [Recent outcomes of vitreous surgery for diabetic retinopathy].
abstract: OBJECTIVE
  To investigate background, surgical method, complications, prognosis, and prognostic factors in patients undergoing vitrectomy for diabetic retinopathy.
  
  
  METHODS
  Three hundred and forty eyes of 261 patients undergoing vitrectomy for diabetic retinopathy in five recent years were studied regarding background, surgical method, complications, and visual prognosis. Factors influencing postoperative visual acuity and complications were also examined using univariate and multivariate analyses.
  
  
  RESULTS
  Final postoperative visual acuity (FPVA) improved in 226 eyes (66%). FPVA of 0.1 or better and 0.5 or better was achieved in 80% and 45% of all patients, respectively. Postoperative complications occurred in 89 eyes(26%). In the vitreous hemorrhage group, FPVA improved in 86%, and FPVA of 0.5 or better was achieved in 60%. Postoperative complications were most common in the traction detachment group and the percentage was 40%. Factors influencing FPVA were preoperative visual acuity, postoperative complications, indications for surgery, and preoperative severity. Factors influencing postoperative complications were patient background, preoperative visual acuity, preoperative severity, and iatrogenic breaks.
  
  
  CONCLUSIONS
  Vitrectomy is a useful method for diabetic retinopathy but postoperative complications must be managed.
