![]() ![]() This type of test tells your doctor if the electrical signals to your brain are slower than normal as a result of optic nerve damage. Attached to your head are wires with small patches to record your brain's responses to what you see on the screen. During this test, you sit before a screen on which an alternating checkerboard pattern is displayed. Optic neuritis can cause any pattern of visual field loss. This test measures the peripheral vision of each eye to determine if there is any vision loss. This test measures the thickness of the eye's retinal nerve fiber layer, which is often thinner from optic neuritis. For atypical cases of optic neuritis, blood may also be tested for MOG antibodies. People with severe optic neuritis may undergo this test to determine whether they're likely to develop neuromyelitis optica. Neuromyelitis optica is linked to an antibody that causes severe optic neuritis. A blood test is available to check for infections or specific antibodies. ![]() An MRI can also rule out other causes of visual loss, such as a tumor. Such lesions indicate a high risk of developing multiple sclerosis. 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.Īn MRI is important to determine whether there are damaged areas (lesions) in your brain. An MRI scan uses a magnetic field and pulses of radio wave energy to make pictures of your body. Other tests to diagnose optic neuritis might include: ![]()
