Optic neuritis (nmo) or multiple sclerosis (ms)? what are the different victims?

Explanation: It is not an either or, but rather a statistical risk. Optic neuritis can turn out to be clinically definite ms in about 20-50% of people. If there is more than one white matter lesion over the brain on an MRI in an optic neuritis patient, by 14 yrs later, about 80% have developed full blown ms. So, very high risk if one looks at the above statistics.

Say what???: This question is confusing! optic neuritis (abbreviated on) is one of many symptoms of ms and results from inflammation in one or both optic nerves. It is one of the most common symptoms of ms and typically causes eye pain and decreased vision in one eye. It does not typically cause complete blindness. Multiple sclerosis (ms) is an autoimmune disorder of the center nervous system. See below.
