title: Pressure sore in a patient who underwent repair of a retinal tear with gas injection.
abstract: OBJECTIVE
  To demonstrate a pressure sore following strict head positioning in a patient who underwent encircling band, vitrectomy and gas injection.
  
  
  METHODS
  A male patient was admitted to the hospital with a large posterior horseshoe tear in the inferior temporal retina with severe vitreous traction and retinal detachment. Encircling band, vitrectomy cryotherapy and gas injection was performed. After surgery the patient was instructed to sit in a face-down position.
  
  
  RESULTS
  A pressure sore resulted from prolonged immobility of the right elbow due to face-down positioning following encircling band, vitrectomy and gas injection.
  
  
  CONCLUSIONS
  A patient may rarely have compulsive personality traits that result in extreme compliance to the physician's recommendations; therefore, general instructions given for head positioning should include permission for a change in position when required, at least for brief periods of time.
