title: Cryoglobulinemia revealed by a Purtscher-like retinopathy.
abstract: OBJECTIVE
  To demonstrate the importance of collaboration between ophthalmologists and internists.
  
  
  METHODS
  Cryoglobulinemia is a systemic vascularite. Ophthalmologic complications are rare and not well known. Purtscher-like retinopathy may occur in this context.
  
  
  METHODS
  We report the case of a patient who presented a severe visual loss in the course of a hepatitis C. The ophthalmic examination shows a both ischemic and hemorrhagic bilateral retinopathy called Purtscher-like retinopathy. Cryoglobulinemia complicating a hepatitis C was discovered in our patient.
  
  
  CONCLUSIONS
  This case illustrates a cryoglobulinemia complicating by a Purtscher-like retinopathy. The diagnosis has been possible thanks to collaboration between ophthalmologists and internists. We propose a few hypotheses to explain retinopathy pathogeny.
