title: [Effectiveness of preoperative panretinal photocoagulation in severe proliferative diabetic retinopathy].
abstract: OBJECTIVE
  To evaluate correlations between the surgical outcomes, either presence or absence of preoperative panretinal photocoagulation and types of retinal detachment in patients undergoing vitrectomy for severe proliferative diabetic retinopathy.
  
  
  METHODS
  We reviewed 67 eyes that underwent vitrectomy for severe proliferative diabetic retinopathy accompanied by either macular tractinal retinal detachment or combined tractinal and rhegmatogenous retinal detachment.
  
  
  RESULTS
  The postoperative visual acuity (p < 0.05) of eyes with preoperative panretinal photocoagulation (PRPC) showed significant improvement. There was a higher success rate of retinal attachment (p < 0.05) than in those without PRPC. There was no significant difference in surgical outcome amang the types of retinal detachment.
  
  
  CONCLUSIONS
  Preoperative panretinal photocoagulation for severe proliferative diabetic retinopathy improves surgical success.
