Your Care Instructions

Optic neuritis is a problem in the eye's optic nerve. This is the nerve that moves light and images from the eye to the brain. Optic neuritis causes the nerve to swell. You may have blurred or double vision or even loss of vision.

Your doctor may not know what caused the problem with your eye. In some cases, a virus infects the nerve. Sometimes the body's defences (immune system) mistakenly attack the body's own cells, such as the nerves. Many people with multiple sclerosis (MS), which is an immune system disease, have optic neuritis at some time. It can be the first symptom of MS.

Your doctor may want to watch your symptoms or may give you medicine, which can reduce the swelling of your optic nerve. In either case, he or she will carefully keep track of your condition.

How can you care for yourself at home?

• Take your medicines exactly as prescribed. Call your doctor or nurse call line if you think you are having a problem with your medicine.
• Follow any directions your doctor gives you to care for your eye.
• Avoid bright lights or use dark glasses to protect the eye.
• Over-the-counter eyedrops, such as artificial tears, may help the eye feel better. Choose a product that does not contain preservatives.
