title: Intraoperative complications of perfluoroperhydrophenanthrene: subretinal perfluorocarbon, retinal slippage and residual perfluorocarbon. Vitreon Study Group.
abstract: BACKGROUND
  An earlier analysis of postoperative complications of the perfluorocarbon liquid perfluoroperhydrophenanthrene (Vitreon) showed a low overall rate of posterior segment complications. A study was conducted to determine the incidence of specific intraoperative complications in a wide variety of vitreoretinal procedures performed by many different surgeons using Vitreon.
  
  
  METHODS
  The records of consecutive patients enrolled in the Vitreon Collaborative Study were reviewed to determine the incidence of subretinal Vitreon, retinal slippage and residual Vitreon. A total of 1867 vitreoretinal procedures performed between Nov. 16, 1989, and Dec. 14, 1994, at 35 participating centres were studied. Vitreon was used as a surgical tool at the surgeon's discretion after informed consent was obtained. The incidence of intraoperative complications was determined, and preoperative, intraoperative and postoperative characteristics were tabulated.
  
  
  RESULTS
  Subretinal Vitreon was observed in 24 patients (1.3%), retinal slippage in 20 patients (1.1%) (15 [6.9%] of the 216 patients with giant retinal tears) and residual Vitreon in 68 patients (3.6%).
  
  
  CONCLUSIONS
  Vitreon can be used as a surgical tool in a wide variety of vitreoretinal procedures with a low incidence of intraoperative complications.
