An epicanthal fold or epicanthic fold is a skin fold of the upper eyelid (from the nose to the inner side of the eyebrow) covering the inner corner (medial canthus) of the eye. This fold covers and appears to lower the inner corners of the eyes, creating the appearance of "slanted eyes."
The presence of an epicanthal fold is normal in people of many though not all groups of East Asian and Southeast Asian descent. Epicanthal folds may also be seen in young children of any race before the bridge of the nose begins to elevate.
An epicanthal fold is also common in people with Down syndrome and is the origin of the (once neutral, now considered offensive) term "mongoloid."
