Epicanthic fold

Epicanthic fold
Epicanthic fold
The epicanthic fold is the skin fold of the upper eyelid covering the inner corner of the eye, more often seen in "Mongoloid" people.[1]
Latin plica palpebronasalis
"Mongoloid" eye according to anthropologist Joseph Deniker

An epicanthic fold, epicanthal fold, or epicanthus is a skin fold of the upper eyelid, covering the inner corner (medial canthus) of the eye.

Other names for this trait include plica palpebronasalis,[2] palpebronasal fold,[3] and Mongolian eye fold.[4]



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 result in epicanthic folds, and vice versa.[1] There are various factors influencing whether someone has epicanthic folds, including race, age, and certain medical conditions.


Mongoloids are more likely than Caucasoids to retain the epicanthic fold with age, although it varies demographically.[verification needed] Anthropologist Ashley Montagu wrote in 1988 that for some Mongoloids the "nose is flatter at the root (the miscalled bridge) and the slight fold of skin over the median part of the eye, the Epicanthic fold, is preserved."[1][dated info]


Many fetuses lose their epicanthic folds after 3 to 6 months of gestation.[5][non-primary source needed]

Medical conditions

Medical conditions that cause the nasal bridge to not mature and project are associated with epicanthic folds. One of the characteristics of Down Syndrome is prominent epicanthic folds.[6] In Zellweger syndrome, epicanthic folds are prominent.[7] Other examples are fetal alcohol syndrome, phenylketonuria, and Turner syndrome.[8]
