Sample item

What is the typical visual-field defect in early primary open-angle glaucoma?

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

The answer and the reasoning

A. Peripheral arcuate field loss

Primary open-angle glaucoma causes progressive optic nerve damage and characteristic peripheral arcuate field defects before central vision is affected.

Option by option

  • A. Peripheral arcuate field loss (correct)

    Correct: arcuate peripheral loss follows retinal nerve fibre bundles.

  • B. Central scotoma from optic neuritis

    Central scotoma is typical of optic neuritis.

  • C. Homonymous hemianopia

    Homonymous loss localizes behind the optic chiasm.

  • D. Sudden complete monocular blindness

    Complete sudden blindness suggests a different vascular event.
