title: A multivariate analysis of anatomic success of recurrent retinal detachment treated with pneumatic retinopexy.
abstract: OBJECTIVE
  The purpose of the study is to determine the success rate of pneumatic retinopexy (PR) after failed scleral buckling and to elucidate the predictors for anatomic failure by multiple logistic regression analysis.
  
  
  METHODS
  Thirty-six eyes with recurrent retinal detachment after failed scleral buckling underwent PR. Intraocular tamponade was attained with SF6 (20 eyes), C3F8 (13 eyes), and air (3 eyes). Median follow-up was 14 months.
  
  
  RESULTS
  Retinal reattachment was obtained in 69.4%. Multivariate analysis identified two risk factors for failure: location of retinal break either on the posterior slope or posterior to buckle (P = 0.01) and extent of retinal detachment greater than two quadrants (P = 0.02).
  
  
  CONCLUSIONS
  Pneumatic retinopexy is an effective alternative to revision surgical operations if the leaking retinal break is located on the buckle.
