Obesity is frequently associated with this condition, which primarily affects women between 20 and 44 years of age. Chronic papilledema may lead to optic nerve injury (see optic nerve diseases) and visual loss (see blindness).
- An idiopathic disorder characterized by chronic increase in the intracranial pressure. It occurs predominantly in obese females of childbearing age. It is associated with papilledema.
