What sign is most characteristic of optic neuritis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Pain on eye movement with reduced colour vision

Optic neuritis commonly causes subacute painful visual loss, dyschromatopsia, and relative afferent pupillary defect in one eye.

Option by option

  • A. Itchy eyelids with crusting

    Crusted lids suggest blepharitis.

  • B. Painless red eye with purulent discharge

    Purulent discharge suggests bacterial conjunctivitis.

  • C. Pain on eye movement with reduced colour vision (correct)

    Correct: painful visual loss and colour desaturation are classic.

    Traumatic mydriasis follows iris injury.
