Sample item

A 17-year-old with tremor and hepatic dysfunction shows a golden brown ring at the corneal periphery. At which layer is the copper deposited?

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

The answer and the reasoning

B. Descemet's membrane

Copper deposits in the peripheral Descemet's membrane in Wilson disease. Slit-lamp examination is needed, and the ring may be absent in hepatic presentations without neurological disease.

Option by option

  • A. Anterior stroma

    The stroma is not the site of copper deposition.

  • B. Descemet's membrane (correct)

    Correct. The ring lies in Descemet's membrane.

  • C. Bowman's layer

    Bowman's layer is the site of calcium in band keratopathy.

  • D. Epithelium

    The epithelium is not the site.
