title: [Vitreous hemorrhage and vitreoschisis].
abstract: OBJECTIVE
  To identify the morphologic characteristics of vitreous especially vitreoschisis in vitreous hemorrhage, aiming at discussing the mechanism and clinical importance of vitreoschisis.
  
  
  METHODS
  Eighty-eight cases (97 eyes) of vitreous hemorrhage were observed among which 32 cases (38 eyes) resulting from PDR, 28 cases (30 eyes) resulting from retinal vasculitis and 28 cases (29 eyes) resulting from retinal vein occlusion. All cases had B-scan examination, some had color Doppler examination. Images were compared with the finding in vitre-ctomy.
  
  
  RESULTS
  Vitreoschisis occurred in 18 cases (47.4%) in PDR group, 10 cases (33%) in retinal vasculitis group and 4 cases (13.8%) in retinal vein occlusion group.
  
  
  CONCLUSIONS
  Vitreoschisis may occur in different kind of vitreous hemorrhage. Recognition of vitreoschisis may aid to complete vitrectomy and reduce some complication after surgery.
