Ophthalmology · Conjunctiva and cornea: Salzmann nodular degeneration
Sample itemA 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.
