Optic neuritis is a disorder characterized by the inflammation of the optic nerve, which transmits visual information from the eye to the brain.  This illness frequently causes an abrupt loss in vision and can affect one or both eyes. Often, autoimmune illnesses such as multiple sclerosis (MS) and neuromyelitis optical are associated with optic neuritis.
Symptoms of Optic Neuritis
The most obvious symptom of optic neuritis is a rapid decline in vision, which can range from slight blurring to complete vision loss. Other symptoms include eye pain, particularly during movement, as well as alterations in color perception—colors appearing less bright or washed out.  Some people may have flashing lights or visual field abnormalities.
Causes and Risk Factors
Autoimmune disorders are the leading cause of optic neuritis, in which the immune system inappropriately attacks the optic nerve. Infections, certain drugs, and inflammatory disorders are also potential contributors.
Treatment Options:
Optic neuritis commonly responds to corticosteroids, which decrease inflammation and expedite recovery. Long-term treatment strategies may be required in cases with underlying diseases such as multiple sclerosis. Early diagnosis and treatment are critical for maintaining vision and controlling associated health conditions.
