Epicanthus - Definition
FRDefinition
An epicanthus is a slight fold in the skin, in the shape of a half-moon, situated at the inner angle of the eye, on the tear duct. It stretches from the upper eyelid to the edge of the nose. An epicanthus is notably the cause of slanted eyes in persons of Asian origin or those suffering from pathologies such as Down syndrome or fetal alcohol syndrome. In certain cases it is sufficiently developed so as to disturb the vision, and can thus be operated upon through ophthalmic surgery.
