Optic nerve compression is when a mass, such as a tumor, forms in the brain and presses on the optic nerve. This causes eye pressure.
If not treated, the optic nerve can die.
On this page:
Optic nerve compression occurs when a mass forms around the brain, presses on the optic nerve or tracts, and affects vision. This mass might be a tumor or bony growth.
Over time, optic nerve compression can lead to optic nerve death (optic neuropathy).
The most common symptom of optic nerve compression is vision loss or worsening in your vision.
Vision loss can have many causes, including normal aging and problems with any part of the eye. The optic nerve is the nerve that transmits the signal from the eyeball back to the brain.
Optic nerve compression may occur anywhere from inside the eye itself all the way to where the nerve meets the nerve from the opposite eye, at the "optic chiasm," where the nerves meet and split back into the brain.
Compression of the nerve can thin the myelin around the nerve or cause loss of the tiny blood vessels that feed the nerve, both resulting in vision loss.
Optic nerve compression from masses is often very slow and can be missed until it becomes severe.
When you have optic nerve compression, the most common symptom is worsening or loss of your vision.
Other symptoms may include:
Sudden vision loss is rare with optic nerve compression unless the compression cause is a bone fragment from trauma.
To diagnose optic nerve compression, your doctor will:
For most people, the best treatment for optic nerve compression is surgery.
Surgeons remove, or move, what's pressing on the optic nerve before it causes lasting damage.
UPMC surgeons treat optic nerve compression with the Endoscopic Endonasal Approach (EEA).
Our expert team of neurosurgeons, otolaryngologists, and ocular surgeons helped create the EEA. They were some of the first in the world and are among the most experienced in the world, always refining this technique.
This minimally invasive surgical approach allows surgeons to access the eye and optic nerve through your nose or nasal cavities without making an incision. Surgeons then remove the tumor or open the bony canal that's compressing the optic nerve.
With EEA:
Pros of EEA:
Other options for optic nerve decompression or mass removal include the lateral orbitotomy approach and eyebrow craniotomy. These approaches are performed by oculoplastic surgeons and neurosurgeons working as a team to remove the tumor or compression.
UPMC's neurosurgical team will look at your health issue from every angle to find a treatment that will least disrupt your:
We may suggest both surgery and non-surgical treatments treatments for the best returns. The exact approach chosen depends on the patient's goals, safety, and the location of the mass of compression.
