title: Papilledema and idiopathic intracranial hypertension.
abstract: OBJECTIVE
  Papilledema is one of the most concerning physical examination findings in neurology: it has a broad differential diagnosis of intracranial (and occasionally spinal) pathology associated with increased intracranial pressure. Papilledema impairs axoplasmic flow within the optic nerves and compresses the optic nerves externally; it may lead to profound visual loss. Thus, detection of papilledema and assessment of visual function are essential to patient management. This article reviews the treatment of papilledema-related visual loss in pseudotumor cerebri syndrome, one of the most common causes of papilledema encountered by neurologists.
  
  
  RESULTS
  Results from the Idiopathic Intracranial Hypertension Trial (IIHTT), the first randomized, double-masked, placebo-controlled trial for the treatment of patients with mild visual loss from idiopathic intracranial hypertension, were published in April 2014. The IIHTT provides the first evidence-based treatment recommendations, showing the benefit of acetazolamide and weight loss for improving visual status in patients with mild visual field loss from idiopathic intracranial hypertension.
  
  
  CONCLUSIONS
  A detailed ophthalmic examination, including perimetry, is critical to the evaluation, treatment, and assessment of treatment response in patients with papilledema.
