Other side effects include mood changes and weight gain. Steroid medications used to treat optic neuritis subdue your immune system, which causes your body to become more susceptible to infections.

Most people regain normal or near-normal vision within several months, but a partial loss of color discrimination might persist. Most people have some permanent optic nerve damage after an episode of optic neuritis, but the damage might not cause permanent symptoms. Certain genetic mutations might increase your risk of developing optic neuritis or multiple sclerosis.Ĭomplications arising from optic neuritis may include: Optic neuritis occurs more often in white people. Women are much more likely to develop optic neuritis than men are. Optic neuritis most often affects adults ages 20 to 40. Risk factors for developing optic neuritis include: Ethambutol, used to treat tuberculosis, and methanol, a common ingredient in antifreeze, paints and solvents, are associated with optic neuritis. Some drugs and toxins have been associated with the development of optic neuritis. Diseases such as sarcoidosis, Behcet's disease and lupus can cause recurrent optic neuritis.

Bacterial infections, including Lyme disease, cat-scratch fever and syphilis, or viruses, such as measles, mumps and herpes, can cause optic neuritis. When symptoms of optic neuritis are more complex, other associated causes need to be considered, including: Recovery from MOG attacks is usually better than recovery from neuromyelitis optica. Similar to MS and neuromyelitis optica, recurrent attacks of inflammation can occur. This condition can cause inflammation to the optic nerve, spinal cord or brain. Myelin oligodendrocyte glycoprotein (MOG) antibody disorder.Still, neuromyelitis optica is more severe than MS, often resulting in a diminished recovery after an attack compared with MS. Neuromyelitis optica has similarities to multiple sclerosis, but neuromyelitis optica doesn't cause damage to the nerves in the brain as often as multiple sclerosis does. In this condition, inflammation affects the optic nerve and spinal cord. Your risk of developing multiple sclerosis after optic neuritis increases further if an MRI scan shows lesions on your brain. In people with optic neuritis, the risk of developing multiple sclerosis after one episode of optic neuritis is about 50% over a lifetime. Multiple sclerosis is a disease in which your autoimmune system attacks the myelin sheath covering nerve fibers in your brain. The following autoimmune conditions often are associated with optic neuritis: Optic neuritis disrupts this process, affecting vision. Normally, the myelin helps electrical impulses travel quickly from the eye to the brain, where they're converted into visual information. It's believed to develop when the immune system mistakenly targets the substance covering your optic nerve, resulting in inflammation and damage to the myelin. The exact cause of optic neuritis is unknown. You have unusual symptoms, including vision loss in both eyes, double vision, and numbness or weakness in one or more limbs, which can indicate a neurological disorder.Your symptoms worsen or don't improve with treatment.You develop new symptoms, such as eye pain or a change in your vision.Some can lead to permanent vision loss, and some are associated with other serious medical problems. Some people with optic neuritis report seeing flashing or flickering lights with eye movements.Įye conditions can be serious. You might notice that colors appear less vivid than normal. Optic neuritis often affects color perception. Side vision loss can occur in any pattern, such as central vision loss or peripheral vision loss. Noticeable vision loss usually develops over hours or days and improves over several weeks to months. Most people have at least some temporary reduction in vision, but the extent of loss varies.

Sometimes the pain feels like a dull ache behind the eye. Most people who develop optic neuritis have eye pain that's worsened by eye movement.
