Question: What causes optic nerve tumors?

In most cases, the cause of optic nerve gliomas is not known. It’s important to understand that these and other brain tumors most often occur with no known cause. There’s nothing that could have been done or avoided that would have prevented the tumor from developing.

How common are optic nerve tumors?

Optic nerve gliomas are benign (non-cancerous) brain tumors that grow on the nerves that carry vision from the eyes to the brain (the optic nerves). Optic nerve gliomas are found in approximately one in five children with NF1. These tumors commonly arise in young children and can affect their vision.

How do you get rid of an optic nerve tumor?

Surgery and radiation therapy are two possible ways of treating optic nerve glioma. Your doctor can determine which type of treatment is best for you. Surgery is not always an option. Surgery may be performed if doctors believe they can use it to completely remove the tumor.

Are optic nerve tumors cancerous?

Optic nerve tumors are growths that occur on the optic nerve. The majority of these tumors are benign, but some are highly malignant and can be very dangerous if left untreated. You may experience progressive vision loss, most often in only one eye and starting with the peripheral vision.

Can optic nerve gliomas be cured?

Although optic nerve gliomas are serious tumors, they usually grow slowly, have a high cure rate, and rarely cause blindness. Most kids do well with treatment, and further vision loss usually is prevented.

What are the symptoms of a tumor behind the eye?

Some of the most common symptoms include:

  • Bulging of the eye, usually without pain.
  • Swelling of the eye.
  • Changes in vision or vision loss.
  • Eye redness.
  • Burning or itching in the eye.
  • The feeling that something is in the eye.

What kind of brain tumor causes vision problems?

A tumour in the occipital lobe causes difficulties with vision, such as visual loss, or identifying objects or colours. Alternatively, it may cause loss of vision on one side.

Can surgery be done on optic nerve?

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).

How long does it take for an optic nerve to heal?

Typically, patients begin to recover 2 to 4 weeks after the onset of the vision loss. The optic nerve may take up to 6 to 12 months to heal completely, but most patients recover as much vision as they are going to within the first few months.

Can we regenerate optic nerve?

Human optic nerve cells lack the ability to regenerate and to re-establish neuronal wiring from the eye to the brain. Additionally, there are no FDA-approved drugs or surgeries that prevent death of the cells that make the optic nerve, block nerve degeneration or stimulate nerve regeneration.

Can a tumor behind the eye be removed?

There are various ways to treat eye tumors, depending on the diagnosis, size and aggressiveness of the tumor, and other factors. Certain small tumors may respond to laser treatment or freezing (cryosurgery). In some instances, it is possible to remove a tumor surgically and still preserve vision.

Can pituitary tumors cause vision problems?

Patients with small pituitary tumors do not typically develop visual symptoms. However, if a pituitary tumor has grown larger (usually more than 1 cm), then a patient can develop visual loss in one or both eyes. One pattern of visual loss that characteristically occurs is reduced peripheral vision to both sides.

Can a brain tumor cause optic nerve damage?

Brain Tumor and Visual Disturbances

Both benign and malignant tumors can damage the optic nerves, directly or indirectly by compressing them through increased pressure on the skull. This can cause problems with a patient’s vision.

How bad is an optic nerve glioma?

Optic nerve glioma is a slow-growing tumor, which typically affects children. 30% of patients have associated NF1 & those have better prognosis. Malignant gliomas (glioblastoma) are rare & almost always occur in adult males with a very poor prognosis & almost certain death within one year.

How common is optic nerve glioma?

Optic nerve glioma accounts for five percent of all childhood brain tumors. Nearly 75 percent of optic nerve gliomas, which may affect one or both eyes, occur in children younger than ten years old.

Has anyone survived glioma?

Only 10% of people with glioblastoma survive five years. However, here I am, 10 years after being diagnosed with the most aggressive form of brain cancer, and I’m not only surviving – I’m thriving. Looking back is surreal.
