Retinoschisis in Pars Planitis

ABSTRACTPurpose: 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 ...
