Epicanthoplasty is a rare eye surgery to modify the epicanthal folds. It can be a challenging procedure because the epicanthal folds overlay the lacrimal canaliculi (tear drainage canals). [ 1 ]
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 possession of "partial epicanthic folds" or "slight epicanthic folds" is noted in the relevant literature.

Girl with epicanthal folds A diagram showing a complete cleft lip and palate. Unevenly positioned eyes that may be crossed or wide-set (hypertelorism) [5] Vision problems due to abnormal facial anatomy, which causes mechanical disturbances of the extraocular muscles, resulting in strabismus (crossed eyes) [3]
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.
This may be accompanied by epicanthal folds (extra fold of skin at the inner corner of the eye), ptosis (drooping of the eyelids), proptosis (bulging eyes), strabismus (inward or outward turning of the eyes), nystagmus (jerking movement of the eyes) and refractive visual errors. The nose may be small, wide, and upturned.
