title: A method to decrease the frequency of unintentional slippage after vitrectomy for rhegmatogenous retinal detachment.
abstract: OBJECTIVE
  To investigate a method for preventing retinal slippage after standard vitrectomy for rhegmatogenous retinal detachment.
  
  
  METHODS
  Eighty six eyes with bullous rhegmatogenous retinal detachment underwent successful standard vitrectomy. Patients were divided into 2 groups. In Group 1, 44 patients started face-down positioning at approximately 10 minutes after the end of the surgery. In Group 2, 42 patients started face-down positioning immediately at the end of the surgery. Postoperative retinal slippage was determined by fundus autofluorescence at 1 month postoperatively. Statistical analysis examined several factors to determine the association between the start time of the face-down positioning and retinal slippage.
  
  
  RESULTS
  Retinal slippage occurred in 63.6% of Group 1 and in 24.0% of Group 2 patients. This difference was statistically significant (P = 0.004, Fisher's exact probability test). Both the extent of retinal slippage (P = 0.029) and the face-down position (P < 0.001) were significantly associated with the retinal slippage.
  
  
  CONCLUSIONS
  Earlier implementation of face-down positioning may prevent retinal slippage after surgery in eyes with rhegmatogenous retinal detachment treated by standard vitrectomy.
