title: Outcome of vitrectomy and chorioretinectomy in perforating eye injuries.
abstract: OBJECTIVE
  To evaluate the anatomical and functional results of patients who underwent pars plana vitrectomy for perforating eye injuries as well as to analyze the benefit of the chorioretinectomy procedure.
  
  
  METHODS
  Retrospective and descriptive study of 24 eyes of 22 patients with perforating eye injuries operated on at the Centro Hospitalar do Porto between January 2006 and December 2012.
  
  
  RESULTS
  An early vitrectomy was accomplished in 67% of the eyes and a delayed vitrectomy in 33% of the eyes. A concomitant chorioretinectomy was carried out in 78%. Final proliferative vitreoretinopathy (PVR) was found in 11%. The anatomical success was 83%. At the final follow-up, 78% had best-corrected visual acuity equal to or superior to 5/200. Of the eyes that underwent early vitrectomy, 58% regained a visual acuity of 40/200 or better, versus 17% of the cases that underwent delayed vitrectomy.
  
  
  CONCLUSIONS
  Early vitrectomy with prophylactic chorioretinectomy seems to be an effective approach to prevent PVR and improve the visual outcome and globe survival in perforating injuries.
