title: A case of bilateral optic neuropathy in a patient on tacrolimus (FK506) therapy after liver transplantation.
abstract: OBJECTIVE
  To report a case of bilateral optic neuropathy in a patient receiving tacrolimus (FK 506, Prograf; Fujisawa USA, Inc, Deerfield, Illinois) for immunosuppression after orthotropic liver transplantation.
  
  
  METHODS
  Case report. In a 58-year-old man receiving tacrolimus after orthotropic liver transplantation, serial neuro-ophthalmologic examinations and laboratory studies were performed.
  
  
  RESULTS
  The patient had episodic deterioration of vision in both eyes, with clinical features resembling ischemic optic neuropathies. Deterioration of vision occurred despite discontinuation of the tacrolimus.
  
  
  CONCLUSIONS
  Tacrolimus and other immunosuppressive agents may be associated with optic nerve toxicity.
