Ophthalmology · Glaucoma: acute angle closure features

Sample item

A 58-year-old woman has severe headache, vomiting, halos around lights and a hazy cornea. What pupil finding is expected?

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

The answer and the reasoning

C. Vertically oval, mid-dilated and fixed pupil

Marked IOP elevation causes iris sphincter ischaemia and a mid-dilated vertically oval, non-reactive pupil. Corneal oedema causes halos, and the anterior chamber is shallow.

Option by option

  • A. Normal round pupil

    The pupil is characteristically abnormal.

  • B. Pinpoint pupil

    A pinpoint pupil is typical of opioids or iritis.

  • C. Vertically oval, mid-dilated and fixed pupil (correct)

    Correct. A fixed oval mid-dilated pupil is typical.

  • D. Small reactive pupil

    A small reactive pupil would not occur with such high pressure.
