title: Organized vitreous hemorrhage masquerading as an optic disc melanocytoma.
abstract: OBJECTIVE
  To present a case of organized vitreous hemorrhage masquerading an optic disc melanocytoma.
  
  
  CONCLUSIONS
  Optic nerve head melanocytoma is a benign slightly pigmented lesion arising from the edge of the disc presenting with a filed defect. Pigmented nature of the lesion in question due to presence of haemosidrin laden macrophages led a diagnostic dilemma. Trans vitreal biopsy confirmed the diagnosis.
  
  
  CONCLUSIONS
  Althought classical in presentation organized blood clots can masquerade a number of lesions including a melanocytoma as in the present scenario.
