Sample item

What does fluorescein dye help reveal on examination of a painful eye?

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

The answer and the reasoning

B. Corneal epithelial defects

Fluorescein stains areas where corneal epithelium is disrupted, helping identify abrasions, ulcers, or dendritic patterns under cobalt-blue illumination; results are interpreted with symptoms and slit-lamp findings.

Option by option

  • A. Retinal artery blood flow

    Retinal flow is evaluated by other ophthalmic imaging methods.

  • B. Corneal epithelial defects (correct)

    Correct: fluorescein highlights corneal epithelial disruption.

  • C. Middle-ear effusion

    Middle-ear effusion requires otoscopy and tympanometry assessment.

  • D. Thyroid gland nodules

    Thyroid nodules are assessed with neck examination and ultrasound.
