title: Surgical outcomes and incidence of retinal redetachment in cases with complicated retinal detachment after silicone oil removal: univariate and multiple risk factors analysis.
abstract: OBJECTIVE
  To analyze the surgical outcomes and retinal redetachment frequency after silicone oil (SO) removal for complex retinal detachment.
  
  
  METHODS
  This institutional-based study included 894 consecutive patients who underwent pars plana vitrectomy with SO endotamponade for complicated retinal detachment. The effects of preoperative best-corrected visual acuity, vitreous base shaving, intraoperative scleral buckling, retinectomy, SO viscosity, duration of SO, and vitreous hemorrhage at the first postoperative week on the risk of redetachment were investigated.
  
  
  RESULTS
  During a mean follow-up of 39.9 months, anatomical success was not achieved in 118 patients (13.2%) after SO removal. On multivariate analysis, risk factors for recurrent retinal detachment included giant retinal tear (adjusted odds ratio [aOR], 12.39; P < 0.001), high myopia (aOR, 2.70; P = 0.011), surgeries without scleral buckling (aOR, 1.97; P = 0.039), inadequate vitreous base shaving (aOR, 117.62; P < 0.001), and vitreous hemorrhage at the first postoperative week (aOR, 12.13; P < 0.001).
  
  
  CONCLUSIONS
  Retinal detachment etiology, inadequate vitreous base shaving, lack of intraoperative scleral buckling, and vitreous hemorrhage at the first postoperative week after SO removal were significant risk factors for retinal redetachment after SO removal, but preoperative visual acuity, SO viscosity, and duration of SO had no significant effect on redetachment.
