Sample item

Which contact-lens complaint needs same-day assessment for microbial keratitis?

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

The answer and the reasoning

C. Painful red eye with photophobia and reduced vision

Contact lens wear increases risk of sight-threatening microbial keratitis; pain, photophobia, corneal opacity, or reduced vision require urgent examination.

Option by option

  • A. Painless eyelid twitching

    Eyelid twitching is usually benign muscle fasciculation.

  • B. Mild itch after removing lenses

    Mild itch alone is less specific for keratitis.

  • C. Painful red eye with photophobia and reduced vision (correct)

    Correct: painful visual loss in a lens wearer is a corneal emergency.

  • D. Stable long-sightedness

    Refractive error is not an acute corneal infection sign.
