How does an MRI diagnose optic neuritis?
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. An MRI is important to determine whether there are damaged areas (lesions) in your brain.
Does optic neuritis show up on MRI?
Optic nerve inflammation can be demonstrated in approximately 95 percent of patients with optic neuritis with gadolinium contrast-enhanced MRI of the brain and orbits (image 1) [6,36-38].
What kind of MRI do I need for optic neuritis?
Even if a diagnosis of idiopathic optic neuritis is made, patients often develop MS, especially in cases in which abnormalities are detected on brain MRI. In patients with optic neuritis, orbital MRI for the evaluation of optic neuritis and brain MRI for the negation of demyelinating disease are usually performed [4].
How long does it take to recover from optic neuritis?
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.
Does optic neuritis mean MS?
Your optic nerve is responsible for transmitting images from your eyes to your brain. Inflammation of this nerve results in optic neuritis. This can cause you to experience vision loss and other troubling symptoms. Optic neuritis is the first sign of MS in about 15 to 20 percent of people who have MS.
How serious is optic neuritis?
Most people have some permanent optic nerve damage after an episode of optic neuritis, but the damage might not cause permanent symptoms. Decreased visual acuity. Most people regain normal or near-normal vision within several months, but a partial loss of color discrimination might persist.
Can you have optic neuritis and not have MS?
You may have vision problems in the future if you have optic neuritis but don’t have MS or another underlying condition. Your prognosis for improved long-term vision is better than if you do have MS, however. Having both optic neuritis and MS may make you more likely to experience recurring symptoms of optic neuritis.
