Epicanthic Fold

Epicanthic fold, epicanthal fold, slant-eye, or epicanthus are names for a skin fold of the upper eyelid, covering the inner corner (medial canthus) of the eye. Other names for this trait include plica palpebronasalis and palpebronasal fold. One of the primary facial features often closely associated with the epicanthic folds is the nose bridge; all else equal, a lower-based nose bridge is more likely to cause epicanthic folds, and vice versa. There are various factors influencing whether someone has epicanthic folds, including geographical ancestry, age, and certain medical conditions.
