title: VITREORETINAL COMPLICATIONS IN EYES WITH BOSTON KERATOPROSTHESIS TYPE I.
abstract: OBJECTIVE
  To describe the spectrum of vitreoretinal complications in eyes with Boston keratoprosthesis type I and evaluate the treatment outcomes.
  
  
  METHODS
  This was a retrospective interventional case series of 23 of 45 eyes that underwent Boston keratoprosthesis from April 2003 to December 2013 and developed vitreoretinal complications. Types of vitreoretinal complications, surgical techniques, and anatomical and visual outcomes were analyzed.
  
  
  RESULTS
  Vitreoretinal complications in eyes with Boston keratoprosthesis included retroprosthetic membranes (n = 11), retinal detachment (n = 6), endophthalmitis (n = 4), epiretinal membrane (n = 4), vitreous hemorrhage (n = 2), and choroidal detachment (n = 1). Twenty of 23 eyes (87%) underwent surgical intervention. Retinal reattachment was achieved in 5 eyes (83%) with significant visual improvement in 3 (50%). Mean preoperative visual acuity improved from 1.84 ± 0.89 logMAR to 1.5 ± 0.87 logMAR (P = 0.01) at the last follow-up. Mean 1.4 surgical procedures were performed per eye. Mean follow-up was 28 months (median: 28 months, range: 5-57 months).
  
  
  CONCLUSIONS
  Retroprosthetic membrane and retinal detachment are most common vitreoretinal complications in eyes with Boston keratoprosthesis. Vitreoretinal complications can be managed by appropriate intervention in such eyes with encouraging anatomical and functional results.
