Idiopathic intracranial hypertension: pseudotumor cerebri.

BACKGROUND

Idiopathic intracranial hypertension (IIH), as defined by the modified Dandy criteria, is a diagnosis of exclusion. It is important to rule out other sight- and life-threatening causes of optic disk edema. IIH primarily affects obese women of childbearing age.

CONCLUSIONS

Permanent visual loss is the primary morbidity associated with IIH. Quantitative perimetry is key in management decision-making to prevent blindness. Treatment consists of weight loss, medication, and surgery.
