Ophthalmology · Conjunctiva and cornea: Salzmann nodular degeneration

Sample item

A woman with old trachomatous scarring has reduced vision and glare. Slit lamp shows a few elevated, bluish-white nodules on the superficial cornea, and the surrounding epithelium is irregular. Which condition is this?

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

The answer and the reasoning

A. Salzmann nodular degeneration

Salzmann nodular degeneration produces raised, bluish-white superficial corneal nodules after chronic keratitis such as trachoma, phlyctenular disease or vernal disease. Superficial keratectomy removes the nodules and improves vision when they are symptomatic.

Option by option

  • A. Salzmann nodular degeneration (correct)

    Correct. Elevated bluish-white nodules after chronic keratitis are typical.

  • B. Band keratopathy

    Band keratopathy is a horizontal band of calcium across the interpalpebral zone with clear lucid holes.

  • C. Terrien marginal degeneration

    Terrien degeneration is a painless peripheral thinning with a lipid line that advances slowly, not elevated central nodules.

  • D. Spheroidal degeneration

    Spheroidal degeneration shows amber, oil-like droplets in the superficial cornea of outdoor workers.
