title: Visual loss in idiopathic intracranial hypertension after resolution of papilledema.
abstract: OBJECTIVE
  To demonstrate that progressive visual field loss may occur after resolution of papilledema in patients with idiopathic intracranial hypertension and persistently elevated intracranial pressure.
  
  
  METHODS
  A patient with idiopathic intracranial hypertension was evaluated with serial Humphrey automated static perimetry after initial treatment and resolution of papilledema.
  
  
  RESULTS
  The patient developed recurrent headache and elevated cerebrospinal fluid pressure. Optic nerve head appearance did not change. Automated perimetry demonstrated reproducible, worsening visual field loss; mean deviation decreased 11 dB in each eye. Visual field defects resolved after optic nerve sheath fenestration.
  
  
  CONCLUSIONS
  Increased intracranial pressure caused visual field loss after resolution of papilledema. Optic nerve sheath fenestration improved visual function in this patient.
