title: [A preliminary investigation on causes of failure of vitreoretinal surgery for complicated rhegmatogenic retinal detachments].
abstract: OBJECTIVE
  To evaluate the failure causes of vitreoretinal surgery for complicated rhegmatogenic retinal detachment.
  
  
  METHODS
  Vitreoretinal (VR) surgery was performed on 477 cases (479 eyes) with complicated rhegmatogenic retinal detachment, the operative procedures including vitrectomy, peeling of pre-retinal membrane, fluid-air exchange, inert gas (SF(6) or C(3)F(8)) or silicone tamponade.
  
  
  RESULTS
  On discharge, the operation was effective in 349 eyes (72.87%) and failed in 130 (27.13%) eyes.
  
  
  CONCLUSIONS
  The multiple stepwise multivariate regression shows that the factors significantly influencing VR surgery are silicone tamponade, giant retinal tears, SF(6) tamponade, iatrogenic tear, anterior proliferative vitreoretinopathy (PVR), subretinal proliferation, PVR, C(3)F(8) tamponade, operative frequency and choroidal detachments.
