Which condition can lead to blindness if left untreated and involves high CSF pressure?

Pseudotumor cerebri, also known as idiopathic intracranial hypertension, is characterized by elevated intracranial pressure without an identifiable cause. This condition can cause various neurological symptoms, including headaches, visual disturbances, and in more severe cases, can lead to permanent vision loss or blindness due to damage to the optic nerve. The increased pressure can cause papilledema, which is swelling of the optic disc, indicating that the optic nerve is being compromised.

Timely recognition and treatment are crucial to prevent serious complications like visual impairment. Treatment options may include weight loss, acetazolamide, and in some cases, surgical interventions to relieve pressure. The association of high cerebrospinal fluid (CSF) pressure in pseudotumor cerebri highlights the importance of addressing this condition promptly to safeguard vision.

Other conditions listed have different mechanisms or consequences that do not directly link them to high CSF pressure or the risk of blindness in the same manner as pseudotumor cerebri.
