title: Vitrectomy for pars planitis complicated by vitreous hemorrhage: visual outcome and long-term follow-up.
abstract: OBJECTIVE
  To characterize the visual results of vitrectomy for nonclearing vitreous hemorrhage in pars planitis.
  
  
  METHODS
  Case series.
  
  
  RESULTS
  All six eyes (100%) had a visual acuity of 20/200 or less preoperatively. Postoperatively, five eyes (83%) improved to a final visual acuity of better than 20/30, and one eye improved to 20/100. The poorer vision of the latter patient was attributed to cystoid macular edema. Postoperative follow-up range was from 1.3 to 9 years (mean, 4.2 years).
  
  
  CONCLUSIONS
  A substantial long-term benefit is seen in patients with pars planitis treated with vitrectomy for nonclearing vitreous hemorrhage. A larger case series will be needed to confirm whether such excellent outcomes can be expected.
