What is Canthus?

In the anatomy, the term "canthus" refers to the corners of the eye, where the upper and lower eyelids meet and create a small notch. Media or nasal, canthus is located in the inner corner of the eye, where it extends towards the nose. There is a side canthus in the outer corner of the eye. Canthi is connected by a transversal plane called bicanthal plane that creates the highest facial area known as the middle surface. This area includes lower eyelids, nose, faces and upper lip. These glands receive their name from an Italian scientist, Giuseppe Vincenzo Ciaccio, who first discovered his existence in 1874. Usually there are two to five additional glands of this type in the upper lid. The glands produce tears that keep their eyes lubricated and without debris. It is also located in the inner corner of the OKAE Canaliculi, which are small channels that siphon fluids, usually in the form of tears, far from the surface of the eye and into the tear bag.

A large percentage of the worldThe population has what is called Epicanthus or Epicanthic, a fold of the skin on the upper eyelid that partly obscures the media canthus. Epicanthic folds are most common in individuals of Asian descent, although native Americans, Inuits and members of ocean ethnic groups also have epicáneic folds. When epicanthus is present, the eye occupies a narrower appearance that is often described as a "almond shape". The reason for the existence of Epicanth is not entirely clear, although the common hypothesis states that it provides special protection against ultraviolet rays.

Canthi can be influenced by a number of health conditions. Individuals with genetic syndrome known as Waardenburg's syndrome often represent a lynx known as Dystopia Canthorum or Telecanthus. Dystopia Canthorum results in Canthi widely deployment, although pupils and the rest of the eyes are set at normal distance. Media canthus is also susceptible to the growth of cancerous tumors. Many health conditions related to abnormalitiesRomos, such as Down's syndrome and fetal alcohol syndrome, may result in the formation of epicanth in individuals who are not genetically predisposed to epicant folds.

Since the area described as the center is most susceptible to the symptoms of aging, some individuals may decide to undergo a form of cosmetic surgery known as canoplasty. Canthoplastics involves the transformation of the lower eyelid by stricter muscles that support lateral cantus. This raises the lower lid of the eye and gives younger appearance. In addition to cosmetic advantages, it may also be in cases where canoplasty lids may be required due to the paralysis of the face or the previous surgery on the eye.
