Many parents notice that their child has spots or patches of black, gray or yellow in the periphery of the cornea (on the white of the eye). Generally speaking, these are pigmented spots of the sclera. Scleral pigment spots are some brown or black pigment spots that appear on the anterior surface of the sclera, where veins pass through. Occasionally, the anterior scleral surface has clear borders, no certain shape, and no elevation. If the spots are shaped like map-like black marble pigment spots, it is called scleral melanosis. This hue can be progressively larger or static and unchanging. It is of no particular clinical significance and is generally free of visual dysfunction. Another kind of dotted pigment is conjunctival pigment nevus. Conjunctival nevi are mostly found near the corneal margin and in the bulbar conjunctiva of the lid fissure, irregularly round, varying in size, with clear boundaries and slightly elevated on the conjunctival surface. The nevus is usually black, with varying shades of pigmentation, and some are brownish red. There are no blood vessels in the nevus. If the nevus suddenly becomes large and rough on the surface with blood vessels growing into it, it indicates the possibility of malignant transformation.
