Learn something new every day More Info The epicanthic fold is a projection of skin between the upper and lower eyelids alongside the nose. It is a common racial characteristic among people with east Asian ancestry. This fold is present in fetuses and infants of any race, and its continued presence can be a sign of a developmental disorder, although this is not always the case. The epicanthic fold is one of several distinguishing characteristics for persons of Asian descent, particularly those whose ancestors originated in the region from Tibet to Japan.
It is also found in Pacific Islanders and Native Americans, who are believed to be descended from Asians, and is not unknown among people of European and African descent. Some scientists speculate that the epicanthic fold may have been an aid to vision for the people residing in or near the Mongolian desert, providing protection from either glare or airborne sand particles.
This is only a theory, however, as the genetic background behind such racial characteristics is still not well understood. Asian people faced systematic racism when migrating to nations such as the U. In the midth century, some Asians and Asian-Americans actually elected to have plastic surgerycalled epicanthoplasty, to eliminate their folds and make them appear more Western.
Epicanthoplasty is a complicated procedure because of the risk of damage to the tear ducts. By contrast, the epicanthic fold is also seen as a sign of exotic beauty in America or Europe, where it is often a rare feature.
The epicanthic fold is sometimes visible during the early development of infants, no matter what their racial background. In non-Asian children, this will often vanish as the facial structure becomes more defined. This is not always the case, however; concerned parents should consult with a medical professional. This term is now considered imprecise and possibly offensive.
Perdido - My cousin went to a surgeon in Los Angeles who is an expert at eye enlargement. The surgeon is Asian himself, so he understands the desire firsthand. He also has extensive knowledge of working with the epicanthic fold.
Can a white person have an epicanthus (epicanthic eye fold)?
He was able to redistribute the tissue around the inner eye and lower eyelid to prevent scarring. He made the epicanthic tissue flexible, so this reduced the tension that was holding it in place and hiding her eyes. He didn't want to totally remove the fold, because that would take away the look of her heritage. He restructured it just enough to make her happy and look natural.Q--Is there a theory that explains the evolutionary advantage of the shape of the eyes found among Asian people? A--There is no complete evolutionary explanation for the apparent slant of the eyes common to Asians.
The configuration, not actually the shape of the eyeball, results from a fold of skin of the upper eyelid, the epicanthic fold, which tends to cover the inner corner of the eye. Frank Poirier, a physical anthropologist at Ohio State University, says the classical explanation of epicanthic fold depicts it as an adaptation to the tropical and arctic regions where many Asians live. The fold is described as a sun visor protecting the eyes from overexposure to ultraviolet radiation or as a blanket insulating them from the cold.Shocking DNA Results!! What Is My Ethnicity!!! Why Do I Look Asian!
According to Poirier, the problem with this theory is that a substantial portion of the Asian population evolved in areas outside of the tropical and arctic regions. In addition, he says epicanthic fold is not limited to Asians. Kennedy had a variance of the fold and it is found among Europeans, especially the Irish,'' he said.
Poirier attributes the fold to pleiotropic genes--single genes that control more than one characteristic or function--but he has no explanation for its origin.Epicanthic fold, epicanthal fold, epicanthus is the fold of upper skin over the eye lid that is from one end of the eye to the other. It is a physical feature but generally associated with race as it is found mostly on Asian. This fold can be seen on some people from Native America and sometimes even on Europeans.
The western beauty standard also considers epicanthic fold unpleasant and round eyes beautiful. Due to this, it has given rise to a lot of face alteration among Asians. Well, as per the classic explanation for the fold, it was developed in tropical regions to protect from UV rays or in Arctic regions as insulation from the cold.
Germans who look Asian
Some scientists also think that the epicanthic fold may have been a tool for vision to the people residing in or near the Mongolian desert as it gave protection from either glare or airborne sand particles. Epicanthic fold can be mostly seen on Asians. Is epicanthic fold just because of genetics? Well, no.
But this term was also used to discriminate Asians by Caucasians. There are prejudices with Asians who have epicanthic fold. The round eyes with perfect eyelashes are considered beautiful which genetically, the Asian are not gifted with.
This is all because of the Western beauty standards that has been followed.
A number of Asian women have taken aid of surgery to get rid of their epicanthic fold. The surgery is called Blepharoplasty. It is a type of cosmetic surgery where the skin around the eye is reshaped to create an upper eyelid with a crease. Korea is the country where alarming rates of plastic surgery takes place. It has been culturally accepted surgical alteration that they perform on themselves.
All the fetuses have epicanthic fold no matter the race. Asian born or not, babies when born can have epicanthic fold that will disappear with age. It is to protect the eye of the baby. Having an epicanthal fold is a part of an identity. The Asians can be stereotyped with having an epicanthic fold but it is their identity nevertheless.Epicanthal fold is normally seen in people of East Asian origin.
However, in others it may indicate some other birth defects. Epicanthal folds give the eyes appearance of almond-shaped or boat-shaped eye. Although, this is normal in people of Asciatic descent, children with inherited genetic disorders also have it.
Epicanthal folds may develop in fetuses or infants of non-Asian descent before the bridge of the nose starts elevating. With age, epicanthal fold can change in shape and size. Causes of Epicanthal FoldsAs already mentioned, epicanthal folds are related to different genetic disease.
Down SyndromeDown syndrome is a genetic disorder that causes developmental problems and mental retardation for life.
10 things to know about epicanthal fold
This disorder occurs due to extra copy of chromosome Down syndrome can be identified during prenatal testing. At birth, the condition is diagnosed by physical features of an infant.
Children with Down syndrome have flat face, short neck, abnormally shaped ears and short stature. Due to flat face and epicanthal folds, these children appear like Mongolians. Turner Syndrome Turner syndrome is genetic disorder that occurs due to abnormality of one X chromosome. It affects only women, and they have only 45 chromosomes.
It is a rare condition that affects about 1 in every 2, girls. Patients with Turners syndrome are recognized by webbed neck, short stature, a hollow appearance to the chest, lack of secondary sex characteristic, lymphedema and skeletal, autoimmune, dermatological and renal problems. Fetal Alcohol SyndromeThis genetic disorder occurs when the mother drinks too much alcohol during pregnancy.
This can lead to low birth weight, delayed growth, abnormal facial features, vision and hearing problems and problems with central nervous system. Children with fetal alcohol syndrome have epicanthal folds. William syndrome is characterized by different medical problems, including cardiovascular disease, high blood pressure, kidney problems, developmental delays, and learning disabilities. Physical appearance of children with William syndrome is distinguished by small stature, small upturned nose, long upper lip, wide mouth, puffiness around the eyes and epicanthal folds.
Noonan syndrome is a rare genetic disorder that prevents normal development of different parts of the body. This may result in chest deformity, undescended testicles and heart defects.The blood in Irish veins is Celtic, right? Well, not exactly. Although the history many Irish people were taught at school is the history of the Irish as a Celtic race, the truth is much more complicated, and much more interesting than that Research done into the DNA of Irish males has shown that the old Anthropological attempts to define 'Irish' have been misguided.
As late as the s researchers were busy collecting data among Irish people such as hair colour and height, in order to categorise them as a 'race' and define them as different to the British. In fact British and Irish people are closely related in their ancestry. Research into Irish DNA and ancestry has revealed close links with Scotland stretching back to before the Ulster Planation of the early s. But the closest relatives to the Irish in DNA terms are actually from somewhere else entirely!
Medieval map of Ireland, showing Irish tribes. Irish origin myths confirmed by modern scientific evidence The earliest settlers came to Ireland around 10, years ago, in Stone Age times. There are still remnants of their presence scatter across the island. Mountsandel in Coleraine in the North of Ireland is the oldest known site of settlement in Ireland - remains of woven huts, stone tools and food such as berries and hazelnuts were discovered at the site in But where did the early Irish come from?
For a long time the myth of Irish history has been that the Irish are Celts. Many people still refer to Irish, Scottish and Welsh as Celtic culture - and the assumtion has been that they were Celts who migrated from central Europe around BCE.
Keltoi was the name given by the Ancient Greeks to a 'barbaric' in their eyes people who lived to the north of them in central Europe. While early Irish art shows some similarities of style to central European art of the Keltoihistorians have also recognised many significant differences between the two cultures.
The latest research into Irish DNA has confirmed that the early inhabitants of Ireland were not directly descended from the Keltoi of central Europe. In fact the closest genetic relatives of the Irish in Europe are to be found in the north of Spain in the region known as the Basque Country.
These same ancestors are shared to an extent with the people of Britain - especially the Scottish.An epicanthic fold is a skin fold of the upper eyelid that covers the inner corner medial canthus of the eye. Among South Asiansthey occur at very high frequencies among the Bhutanese Northeast Indians Kiratiand certain Adivasi  tribes of eastern India.
Epicanthic folds also occur, at a considerably lower frequency, in other populations: Europeans e. Its use, therefore, as a phenotypic marker to define biological populations is debatable. The epicanthic fold is often associated with greater levels of fat deposition around the eyeball, a feature most accentuated in native North Siberian, Aleut and Inuit populations. The adipose tissue is thought to provide greater insulation for the eye and sinuses from the effects of cold, especially from freezing winds, and to represent an adaptation to cold climates.
It has also been postulated that the fold itself might provide a level of protection from snow blindness. Though its appearance in peoples of Southeast Asia can be linked to possible descent from cold-adapted ancestors, its occurrence in various African peoples precludes a cold-adaptive explanation for it appearing in the latter groups. The epicanthic fold found in some African people has been tentatively linked to protection for the eye from the high levels of ultraviolet light found in desert and semi-desert areas.
Many fetuses lose their epicanthic folds after three to six months of gestation. The epicanthic fold is sometimes found as a congenital abnormality. Medical conditions that cause the nasal bridge not to mature and project are associated with epicanthic folds. He used the term mongoloid for the condition. This was derived from then-prevailing ethnic theory  and from his perception that children with Down syndrome shared physical facial similarities epicanthic folds with those of Blumenbach's Mongolian race.
While the term "mongoloid" also "mongol" or "mongoloid idiot" continued to be used until the early s, it is now considered pejorative and inaccurate and is no longer in common use about medical conditions. In Zellweger syndromeepicanthic folds are prominent. From Wikipedia, the free encyclopedia.
