Does blood pressure affect optic nerve?

High blood pressure can lead to stroke which can also cause vision loss. In addition to threatening the anatomy of the eye, high blood pressure can also cause a stroke, which can impair the optic nerve or damage the area of the brain responsible for processing images.


How does pressure affect the optic nerve?

Experts believe that when the pressure inside your eye gets too high, it can damage the optic nerve and cause vision loss. And studies show that lowering eye pressure can help stop vision loss from glaucoma. That's why it's important to control the pressure inside your eyes.

Can high blood pressure cause optic nerve swelling?

Papilledema refers to the swelling of the optic nerve due to increased pressure inside the cranium. There are various possible causes, including a mass, a hemorrhage, and meningitis. Some other conditions cause optic nerve swelling without intracranial pressure.

Can the optic nerve repair itself?

Damage to the optic nerve is irreversible because the cable of nerve fibers doesn't have the capacity to regenerate, or heal itself, when damage occurs. This is why glaucoma is an incurable disease at this point, and why early detection is so important.
