What is decompression of the optic nerve?
Optic nerve sheath decompression, more commonly known as optic nerve sheath fenestration (ONSF), is a surgical procedure performed to decompress the optic nerves by creating a window in the optic nerve sheath to release CSF from the subarachnoid space around the optic nerve.
What causes flattening of the optic nerve?
The most common is poor blood flow. This is called ischemic optic neuropathy. The problem most often affects older adults. The optic nerve can also be damaged by shock, toxins, radiation, and trauma.
Can optic nerve compression be treated?
The most common symptom of optic nerve compression is gradual vision loss or a gradual worsening in your vision. Surgery is the most common treatment to correct optic nerve compression. At UPMC, the preferred surgical treatment for optic nerve compression is the Endoscopic Endonasal Approach (EEA).
What happens when the optic nerve is compressed?
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.
Does brain MRI show optic nerve?
MRI allows excellent depiction of the intricate anatomy of optic nerves due to its excellent soft tissue contrast without exposure to ionizing radiation, better delineation of the entire visual pathway, and accurate evaluation of associated intracranial pathologies.
What causes the optic nerve to enlarge?
Papilledema is swelling of your optic nerve, which connects the eye and brain. This swelling is a reaction to a buildup of pressure in or around your brain that may have many causes. Often, it’s a warning sign of a serious medical condition that needs attention, such as a brain tumor or hemorrhage.
How can I cure my optic nerve?
Optic neuritis usually improves on its own. In some cases, steroid medications are used to reduce inflammation in the optic nerve. Possible side effects from steroid treatment include weight gain, mood changes, facial flushing, stomach upset and insomnia. Steroid treatment is usually given by vein (intravenously).
Does MRI show optic nerve damage?
During an MRI to check for optic neuritis, you might receive an injection of a contrast solution to make the optic nerve and other parts of your brain more visible on the images. An MRI is important to determine whether there are damaged areas (lesions) in your brain.
Can a swollen optic nerve mean nothing?
It’s possible for the optic nerve to be inflamed without affecting vision. A careful, medical evaluation of the eye can generally pinpoint optic neuritis even if you don’t have symptoms.
What causes compression of the optic nerve in the eye?
Optic Nerve Compression. 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.
What does orbital decompression do to Your Eyes?
Orbital decompression is done to reduce the bulgy appearance of the eyes, either for functional (medical) or cosmetic reasons (cosmetic orbital decompression), by removing orbital fat and bone. Another rare indication for orbital decompression is compressive optic neuropathy.
How is surgery done on the optic nerve?
This state-of-the-art, minimally invasive surgical approach allows surgeons to access the optic nerve through the natural corridor of the nose, without making an open incision. This surgical technique allows doctors to see the nerve well without making an open incision.
How is EEA surgery used to treat optic nerve compression?
This surgical technique allows doctors to see the nerve well without making an open incision. Surgeons then can remove a tumor or open the bony canal that is compressing the optic nerve. EEA offers the benefits of no incisions to heal, no disfigurement, and a faster recovery time.
