Sample item

Which feature suggests acute angle-closure glaucoma rather than simple conjunctivitis?

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

The answer and the reasoning

C. Severe eye pain with halos, nausea, and a mid-dilated pupil

Acute angle closure causes a rapid rise in intraocular pressure with pain, corneal haze, halos, nausea, and a poorly reactive mid-dilated pupil.

Option by option

  • A. Itchy bilateral eyes with watery discharge

    Itching and watering favour allergic conjunctivitis.

  • B. Mild foreign-body sensation after dust exposure

    Minor irritation has a less dangerous differential.

  • C. Severe eye pain with halos, nausea, and a mid-dilated pupil (correct)

    Correct: painful red eye with systemic symptoms is an ocular emergency.

  • D. Painless subconjunctival haemorrhage

    Subconjunctival haemorrhage is usually painless and benign.
