Ophthalmology · Cornea: band keratopathy

Sample item

A child with juvenile idiopathic arthritis develops a horizontal greyish band of calcium in the interpalpebral cornea. What treatment removes it?

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

The answer and the reasoning

B. Chelation with EDTA

Band keratopathy is calcium deposition in Bowman's layer of the interpalpebral zone, often secondary to chronic uveitis. EDTA chelation after epithelial removal clears it.

Option by option

  • A. Steroid drops

    Steroids treat inflammation but do not remove calcium.

  • B. Chelation with EDTA (correct)

    Correct. EDTA binds calcium and clears the band.

  • C. Cross-linking

    Cross-linking is for keratoconus.

  • D. Atropine drops

    Atropine does not affect corneal deposits.
