Multiple Sclerosis (MS): Optic Neuritis (Part 1)

Optic neuritis is a form of relapse that can cause blurring of vision, loss of vision, and pain in the eye and behind the eye. It is caused by inflammation of the optic nerve which starts in the brain stem and works its way to the back of the eyeball.

Visual evoked potentials (VEPs) and optical coherence tomography (OCT) are tests used to assess for optic neuritis or damage to the optic nerve pathway. Transverse myelitis is an inflammation of the spinal cord that can affect motor and sensory functions as well as cause pain.

Somatosensory evoked potentials (SSEPs) is another test used to localize damage but is not used as commonly due to improved MRI quality.
