An epicanthal fold, '''epicanthic fold''' or '''epicanthus''' 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 Human Eye . This fold covers and appears to lower the inner corners of the eyes, creating the appearance of "slanted eyes." It is commonly known amongst Asians as "single-eyelids", as opposed to "double eyelids". The occurrence of the epicanthic fold is believed to be an evolutionary defense against both the extreme cold as well as the extreme light that occurs in the Eurasian arctic and north. A few have opted to have them minimized by Blepharoplasty . Epicanthal folds may also be seen in young children of any Race before the bridge of the nose begins to elevate. The distribution of epicanthal folds is numerous. It can also be found in significant numbers amongst Native Americans , the Khoisan of Southern Africa, many Central Asian s and some people of Sami origin. The presence of epicanthal folds is normal in people of many, though not all, groups of East Asian and Southeast Asian descent. It also occurs sometimes on people of South Asian descent. Children of a parent with a pronounced epicanthal fold and one without an epicanthal fold will have varying degrees of epicanthal folds as a result. Epicanthal folds are also common in people with Down Syndrome . SEE ALSO EXTERNAL LINKS
