Corneal pigmentation

Photo by Professor Chua

This 28 year-old Nigerian woman complains of ocular discomfort. The Schirmer's test shows poor tear production and she was put on regularly artifical tear with good result. The slit-lamp examination reveals right conjunctival melanosis involving the limbus and there are corneal pigmentations. The pigmentations are caused by migration of the melanocytes from the limbus and are of not clinical significance.
