An epicanthic fold, epicanthal 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 eye. The trait arises because the eyelid muscles are weaker or lower compared with people who do not have this epicanthic fold, resulting in a lower fold in the eyelid, when the eyes are open. The fold gives the eyes of East Asians a characteristic shape which is narrower and almond-like in comparison to most Westerners, whose eyes appear rounder.
The term "epicanthic fold" refers to a visually categorized feature of the eyelid; however, there are different underlying causes.
Population distribution
The epicanthic fold occurs commonly in people of Central Asian, East Asian and Southeast Asian descent as a result of adaptive significance, such as the Mongols, Hazaras, Chinese, Koreans, Japanese, Vietnamese, Kazakhs and some South and Southeast Asians like Burmese, Filipinos, Cambodians, Malays, Thais, Bhutanese,Northern Bangladeshis, Northern Nepalis, Tibetans, Ladakhis and others. It also occurs in Afro-Asians, Khoisans (Capoids) in Africa and Madagascar, and certain groups from southern Sudan such as the Dinka and the Nuer. Epicanthic folds can also be found inherited among some Oceanic peoples including Tongans, Samoans, Micronesians, and Hawaiians. Many Inuits and some Native Americans may have it as well. Also occurs in Scandinavians, and is common in Scandinavian babies.
Anyone care to vouch for that last statement? Scandinavians with epicanthic folds?
And on another note, anyone here with em?
I think I've got one, but not in the typical Asian fashion, got the fold, but I also show two instead of one eyelids:
