Idiopathic intracranial hypertension occurs when there's unexplained pressure buildup in the fluid that cushions the brain in the skull, researchers explain in the journal Neurology.

Researchers found that changes in the optic disc -- the place inside the eye where the optic nerve connects to the retina -- can predict who will develop blind spots in their vision or lose sharpness of vision.
