Optic Neuritis
Symptoms of Optic Neuritis
Optic neuritis causes vision loss, which may be mild or severe and may occur in one or both eyes. Loss of vision may increase over several days. Vision in the involved eye or eyes can range from almost normal to complete blindness. Color vision may be particularly affected, but the person may not realize it. Most people have mild eye pain, which often feels worse with eye movement. Depending on the cause, vision usually returns within 2 to 3 months but not always completely. Some people have repeat episodes of optic neuritis.
