The value of tests evaluating visual functions in detecting overt or subclinical optic neuritis in multiple sclerosis

- We investigated visual tests and disability scales in detecting optic neuritis (ON).
- Low-contrast visual acuity (LCVA) tests were significantly related to OCT, VEP.
- LCVA tests were found to be associated with EDSS, MSFC and NEI-VFQ25.
- LCVA tests added to follow-up visits to suggest subtle visual impairments in MS.
