What condition can idiopathic intracranial hypertension lead to if untreated?

Idiopathic intracranial hypertension (IIH) is characterized by increased intracranial pressure without any obvious cause. If left untreated, one of the significant complications that can arise is optic nerve damage. This occurs due to the pressure exerted on the optic nerves, which can lead to swelling of the optic nerve head (papilledema) and, subsequently, visual disturbances or even permanent vision loss.

The development of optic nerve damage highlights the importance of timely diagnosis and treatment of IIH to preserve vision. While other conditions like hydrocephalus, seizures, and headaches may be associated with elevated intracranial pressure, they are not the primary concern or the most severe consequence directly linked to untreated idiopathic intracranial hypertension. The direct impact on the optic nerve underscores the critical need for monitoring and managing patients with this condition effectively.
