title: Pars plana vitrectomy with silicone oil tamponade in failed scleral buckle surgery.
abstract: OBJECTIVE
  This study aimed to evaluate the anatomical and functional outcomes of secondary pars plana vitrectomy (PPV) after failed scleral buckling (SB) surgery and to compare it with primary PPV for rhegmatogenous retinal detachment (RRD), including complicated proliferative vitreoretinopathy cases.
  
  
  METHODS
  Retrospective series in a tertiary care centre.
  
  
  METHODS
  One hundred and twenty consecutive patients.
  
  
  METHODS
  The medical records of patients who underwent PPV with silicone oil tamponade for RRD were reviewed. Forty-four eyes were operated on for primary RRD (primary PPV group), and 76 eyes were operated on for failed SB surgery (secondary PPV group). The single-operation anatomical success rate, final anatomical success rate, and best-corrected visual acuity preoperatively, at 6 months, at 1 year, and at final follow-up were analyzed.
  
  
  RESULTS
  The single-operation anatomical success rate was 74.2% in the primary PPV group and 77% in the secondary PPV group (p = 0.48). The final anatomical success rate was 90.3% in the primary PPV group and 91.8% in the secondary PPV group (p = 0.55). The number of cases with visual acuities of 3 visual categories (20/50 or better, 20/200 to 20/50, less than 20/200) was not statistically different at each time point.
  
  
  CONCLUSIONS
  Consequent PPV with silicone oil tamponade for failed SB surgery seems not to have inferior anatomical and functional outcomes when compared with primary PPV for RRD.
