title: Case report: bilateral simultaneous central retinal vein occlusion in Waldenström's macroglobulinemia.
abstract: BACKGROUND
  We report a case of bilateral simultaneous central retinal vein occlusion (CRVO) in Waldenström's macroglobulinemia.
  
  
  METHODS
  We report the case of a 60-year-old woman who presented with decreased vision in both eyes.
  
  
  RESULTS
  Ophthalmoscopic examination showed scattered retinal hemorrhages and venous tortuosity with macular edema bilaterally. The patient had a history of hypertension and was under investigation for lethargy, recurrent epistaxis, and fainting episodes. Serum protein electrophoresis showed an M-spike in the gamma region. Bone marrow trephine biopsy confirmed the diagnosis of Waldenström's macroglobulinemia. The patient was treated with plasmapheresis and subsequent chemotherapy, resulting in improvement of ocular and systemic symptoms.
  
  
  CONCLUSIONS
  We report this case to emphasize that in any case of bilateral CRVO, hyperviscosity should be suspected. Serum electrophoresis along with coagulation profiles should be performed as a standard practice in patients with bilateral simultaneous CRVO.
