Sample item

Why does a contact-lens wearer with painful red eye and reduced vision need urgent assessment?

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

The answer and the reasoning

C. Risk of microbial keratitis and corneal ulceration

Contact-lens wear increases risk of microbial keratitis, which can threaten the cornea and vision; pain, photophobia, discharge, or reduced acuity require urgent slit-lamp evaluation and targeted treatment.

Option by option

  • A. Normal age-related floaters

    Benign floaters do not cause a painful corneal presentation.

  • B. Routine refractive error only

    Refractive error does not usually cause acute pain and redness.

  • C. Risk of microbial keratitis and corneal ulceration (correct)

    Correct: contact-lens-associated painful red eye can represent vision-threatening keratitis.

  • D. Simple presbyopia

    Presbyopia causes gradual near-focus difficulty, not a painful red eye.
