Optic Neuritis: Optic neuritis is a condition which is caused by an autoimmune injury to the optic nerve. This produces loss of the fatty insulation ("myelin") around the nerve which makes the nerve not function well. Patients have vision changes (esp. loss of color and brightness sensation), a change in pupil function, and frequently pain with eye movement. MS is usually diagnosed by MRI or a spinal tap.

Eye pain with eye movement. Afferent pupil on exam. Possibly enhancement of the optic nerve on MRI.

Yes: Almost all cases of optic neuritis have pain when moving the affected eye. It is usually accompanied by decreased vision as well. An OD can usually see changes on a dilated exam but not always. If you are concerned about optic neuritis it is important to visit a doctor for evaluation.
