title: Effect of acetazolamide on ocular hemodynamics in pseudotumor cerebri associated with inflammatory bowel disease.
abstract: OBJECTIVE
  To describe the hemodynamic effect of oral acetazolamide administration on ocular perfusion in a patient with pseudotumor cerebri associated with Crohn disease.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  A 20-year-old woman with a 5-year history of Crohn disease presented with a 2-week history of headache and blurred vision in both eyes. Ophthalmologic examination was normal. Fluorescein angiography showed a profound delay in retinal and choroidal perfusion. Lumbar puncture showed an opening pressure of 320 mm water. Therapy was initiated with oral acetazolamide 750 mg per day.
  
  
  RESULTS
  A subjective improvement of symptoms was noted over 4 days. Repeat fluorescein angiography showed resolution of the ocular perfusion deficit. No recurrent symptoms were noted 19 months after cessation of therapy.
  
  
  CONCLUSIONS
  Crohn disease may present with pseudotumor cerebri and severe ocular perfusion deficits that are reversible with oral acetazolamide therapy.
