What causes swelling behind the optic nerve?

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.

What is the most common cause of optic nerve swelling?

The most common cause for ON is inflammatory demyelination of the optic nerve. Demyelination is a process in which the myelin is stripped off by disease. It is believed that ON is an autoimmune process, where for some unknown reason the immune system attacks tissues of the body causing injury.

How do you fix a swollen optic nerve?

Sometimes your healthcare provider may recommend a brief course of steroids, usually injected into your vein, to help your vision improve more quickly and minimize inflammation and swelling. You may also need treatment for another health condition if it’s considered the source of your optic neuritis.

Is optic nerve swelling an emergency?

Bilateral optic disc edema is a true ocular and medical emergency, even in patients without symptoms who are 20/20 and have a normal visual field.

What happens if your optic nerve is swelling?

Optic neuritis occurs when swelling (inflammation) damages the optic nerve — a bundle of nerve fibers that transmits visual information from your eye to your brain. Common symptoms of optic neuritis include pain with eye movement and temporary vision loss in one eye.

Can a brain tumor cause swollen optic nerve?

Eye problems can also occur when a brain tumor exerts pressure on the optic nerve or when pressure within the skull causes the back of the eye (optic disc) to swell (a condition known as “papilledema”).

Can weight gain cause optic nerve swelling?

An estimated 100,000 Americans have it, and the number is rising as obesity becomes more widespread. IIH brings increased pressure within the fluid-filled spaces inside and around the brain. This pressure can cause swelling and damage to the optic nerves that connect the eyes to the brain.

How long does a swollen optic nerve last?

In many cases, optic neuritis is short-lived and resolves by itself without treatment in around four to 12 weeks. The person’s vision improves once the inflammation subsides. In severe or chronic cases, intravenous corticosteroids may be used to speed along recovery.

How serious is a tumor behind the eye?

In addition to damaging vision, eye tumors can spread to the optic nerve, the brain and the rest of the body. Therefore, early diagnosis and treatment are extremely important. Melanoma tends to spread via blood vessels to distant organs.

Can a brain tumor cause eye swelling?

Can optic nerve swelling be treated?

Optic neuritis usually improves on its own. In some cases, steroid medications are used to reduce inflammation in the optic nerve.

Can high blood pressure cause swollen retina?

In some cases, the retina becomes swollen. Over time, high blood pressure can cause damage to the retina’s blood vessels, limit the retina’s function, and put pressure on the optic nerve, causing vision problems. This condition is called hypertensive retinopathy (HR).

How do retinal diseases affect the body?

Retinal diseases can affect any part of your retina, a thin layer of tissue on the inside back wall of your eye. The retina contains millions of light-sensitive cells (rods and cones) and other nerve cells that receive and organize visual information. Your retina sends this information to your brain through your optic nerve, enabling you to see.
