An epicanthic fold or epicanthus [6] is a skin fold of the upper eyelid that covers the inner corner (medial canthus) of the eye. [3] However, variation occurs in the nature of this feature and the presence of "partial epicanthic folds" or "slight epicanthic folds" is noted in the relevant literature.
These variations are not considered defects or abnormalities but rather normal deviations that do not inherently indicate pathology. ... Epicanthic fold; Crease of ...
Epicanthic eye folds are believed to be an adaptation protecting the eye from overexposure to ultraviolet radiation, and is presumed to be a particular trait in archaic humans from eastern and southeast Asia. A cold-adaptive explanation for the epicanthic fold is today seen as outdated by some, as epicanthic folds appear in some African ...
An anatomical variation in humans occurs in the creases and folds of the upper eyelid. An epicanthic fold, the skin fold of the upper eyelid covering the inner corner (medial canthus) of the eye, may be present based on various factors, including ancestry, age, and certain medical conditions. In some populations the trait is almost universal ...
Telecanthus is often associated with many congenital disorders. Congenital disorders such as Down syndrome, fetal alcohol syndrome, cri du chat syndrome, Klinefelter syndrome, Turner syndrome, Ehlers–Danlos syndrome, Waardenburg syndrome [3] often present with prominent epicanthal folds, and if these folds are nasal (as they most commonly are) they will cause telecanthus.

An eyelid is a thin fold of skin that covers and protects the eye. The levator palpebrae superioris muscle helps in the movement of eyelid. The human eyelid features a row of eyelashes along the eyelid margin, which helps in protection of the eye from dust and foreign debris. The main function of eyelid is to keep the cornea moist and clean.
