Sample item

Which examination test detects a relative afferent pupillary defect?

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

The answer and the reasoning

B. Swinging flashlight test

The swinging flashlight test compares direct and consensual pupillary responses and identifies asymmetric afferent input from optic nerve or severe retinal disease.

Option by option

    Ishihara plates assess colour discrimination.

  • B. Swinging flashlight test (correct)

    Correct: alternating light reveals an afferent pupillary asymmetry.

  • C. Schirmer tear test

    Schirmer testing measures tear production.

  • D. Amsler grid only

    Amsler grid assesses central macular distortion.
