Optic Neuritis, Multiple Sclerosis & Ischemic Optic Neuropathy Q & A


What causes optic neuritis?

Optic neuritis is a condition that causes inflammation of the optic nerve, which is responsible for carrying image information to the brain. Although the exact cause of optic neuritis is unknown, studies indicate it develops as part of a faulty immune system response in which the immune system attacks the covering of the optic nerve (the myelin), causing inflammation and damage.

What is ischemic optic neuropathy?

Ischemic optic neuropathy is a condition that causes a sudden loss of vision as a result of a decreased flow of blood to the optic nerve. There are two types of ischemic optic neuropathy: anterior (AION), which occurs when blood flow to the optic nerve head is cut off, and posterior (PION), which develops when blood flow to the back part of the optic nerve is blocked. Both types can cause loss of vision; the total amount of vision loss depends on the extent of nerve damage that occurs.

What are the symptoms of multiple sclerosis optic neuropathy?

Optic neuropathy is a common development in multiple sclerosis, an autoimmune disease that causes damage to the protective sheath that surrounds nerves, called the myelin. MS is highly associated with optic neuritis and neuropathy, which means if you have MS, you're much more likely to develop the other conditions. Symptoms are similar to ischemic optic neuropathy and can include vision loss, the appearance of flashing lights and pain that becomes worse when you move your eye. Some people may also notice a reduction in their ability to perceive clear, sharp colors.

How are these conditions treated?

IV steroids sometimes combined with oral steroids are used to reduce inflammation and treat both ischemic and MS optic neuropathy. Dr. Bose can tell you more about these treatments during your evaluation.
