What does high optic nerve pressure mean?
High pressure inside the eye is caused by an imbalance in the production and drainage of fluid in the eye (aqueous humor). The channels that normally drain the fluid from inside the eye do not function properly.
What would cause pressure on the optic nerve?
Optic nerve compression occurs when a mass (like a tumor or a build-up of pus or other fluid) forms in the brain and presses on the optic nerve, causing eye pressure. It may cause vision problems and can lead to blindness.
How does increased pressure affect the optic nerve?
Open-angle glaucoma The drainage angle formed by the cornea and iris remains open, but the trabecular meshwork is partially blocked. This causes pressure in the eye to gradually increase. This pressure damages the optic nerve. It happens so slowly that you may lose vision before you’re even aware of a problem.
What causes increased eye pressure?
The cause of elevated eye pressure, known as ocular hypertension, is an imbalance in production and drainage of aqueous humor, the fluid inside your eye. Pressure builds as the eye creates new fluid and the channels which normally drain the aqueous humor become obstructed or damaged.
Can you have high pressure in your eyes and not have glaucoma?
But not everyone with high eye pressure will develop glaucoma — and some people with normal eye pressure get glaucoma. Whether you develop glaucoma depends on the amount of pressure your optic nerve can handle — and this amount is different for each person. For most people, eye pressure above 21 is higher than normal.
What does pressure on optic nerve feel like?
Papilledema is a serious medical condition in which the optic nerve at the back of the eye becomes swollen. The symptoms can include visual disturbances, headaches, and nausea. Papilledema occurs when there is a buildup of pressure in or around the brain, which causes the optic nerve to swell.
What causes high eye pressure besides glaucoma?
Medications: Steroid medications, including steroidal eye drops, could cause high eye pressure. Other eye conditions: Conditions including corneal arcus, pigment dispersion syndrome, and pseudoexfoliation syndrome are all associated with ocular hypertension.
How do you fix high eye pressure?

How do you treat high eye pressure?
Prescription eye drops are the most common treatment. They lower the pressure in your eye and prevent damage to your optic nerve. Laser treatment. To lower your eye pressure, doctors can use lasers to help the fluid drain out of your eye.
