Explanation: Optic neuritis is an inflammatory condition affecting the optic nerve, usually affecting young adults, especially females, between 18 and 45 years of age.
Most of the cases are idiopathic in nature; however, it could be associated with demyelinating lesions, of which multiple sclerosis (MS) is the most common cause.
Typical optic neuritis in adults usually presents as acute monocular loss of vision progressing over several hours to days, often associated with ocular pain that worsens on eye movement.
A relative afferent pupillary defect is present in almost all unilateral cases
Subnormal color vision or contrast sensitivity is noted
