Idiopathic Intracranial Hypertension – Ocular Migraine

Idiopathic intracranial hypertension (IIH) develops when high pressure around the brain causes vision changes, headaches, optic atrophy, and eventually blindness. The cause of this hypertension is unknown. When the fluid surrounding the brain and spinal cord builds up in the skull, IIH occurs. This causes extra pressure on the brain and damages the optic nerve. This is a rare disorder that is generally found in children and obese pregnant women. The symptoms closely match those of a brain tumor, which is why it is called pseudotumor cerebri (false brain tumor).
