Giant hairy nevus: preventable cause of amblyopia.
An infant with a congenital giant hairy nevus causing occlusion of the visual axis of the right eye is presented. The nevus was removed at the early age of three weeks because of concern that the child would develop deprivation amblyopia. Since such nevi can undergo malignant changes, early removal may be justified for that reason alone.
