title: Retinoschisis in Pars Planitis.
abstract: OBJECTIVE
  To describe the course of retinoschisis in patients with pars planitis (PP).
  
  
  METHODS
  Chart review of PP patients seen July 2012-September 2014 at a single institution.
  
  
  RESULTS
  Included were 34 patients (68 eyes). Uveitis was bilateral in all cases. Thirteen eyes (19%) developed retinoschisis. In six patients (86%), the schisis was bilateral. The average follow-up of patients with schisis was 7 years; the average best-corrected visual acuity (BCVA) was 20/22 at last follow-up. Schisis was noted to develop or progress in patients with both active and inactive inflammation. Five eyes of five patients underwent vitrectomy; three for disease control, with scleral buckle to reduce residual traction. Two eyes required vitrectomy for retinal detachment with progressive schisis, despite inactive uveitis. Seven eyes remained stable without intervention.
  
  
  CONCLUSIONS
  Retinoschisis is a common complication in patients with PP. It is typically bilateral, and may develop or progress, despite control of uveitis.
