Ophthalmology · Glaucoma: normal tension glaucoma

Sample item

A woman with migraine and cold hands has glaucomatous cupping and field loss, but all IOP readings are 14 to 18 mmHg and the angle is open. What is the likely diagnosis?

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

The answer and the reasoning

C. Normal tension glaucoma

NTG has glaucomatous damage despite normal IOP and is linked to vascular dysregulation, vasospasm, migraine and nocturnal hypotension. The CNTGS showed benefit of 30 percent IOP reduction. Exclude other causes like compressive lesions.

Option by option

  • A. Ocular hypertension

    Ocular hypertension has raised IOP without damage.

  • B. Angle closure glaucoma

    The angle is open here.

  • C. Normal tension glaucoma (correct)

    Correct. Glaucomatous damage with normal IOP is NTG.

  • D. Optic neuritis

    Optic neuritis gives pain and acute loss.
