Q

Diagnose Idiopathic Intracranial Hypertension

A
  1. Papilledema
  2. Visual Field Obscuration (increased blind spot and decreased peripheral field)
  3. MRI showing normal/small ventricles, partially empty sella turcica, flattened optic globe
  4. CSF opening pressure > 250
    (You can do an LP because of cerebral compliance- no risk of herniation with increased ICP- Ani)
