Multiple sclerosis can affect vision in several ways. Problems with sight can be an early symptom of MS.
Optic neuritis is a common eye problem in MS. It is the first symptom that affects about one in five people with MS experience. It is caused by damage to the optic nerve, which connects the eye to the brain. An episode of optic neuritis usually occurs in one eye only. It commonly causes blind spots or areas of poor vision surrounded by an area of normal vision. Colour vision can also be severely affected. Frequently there is pain, particularly during eye movement.
