What Is Heterochromia?

Heterochromia (iris heterochromia; English heterochromia)

Heterochromia

Heterochromia is a kind of physical abnormality, which means that the iris of both eyes has different colors. The color of the eye, especially the color of the iris, is determined by the pigmentation and distribution of the iris tissue. Therefore, any factor that affects the above pigment distribution during the formation process will cause different eye colors.

Basic overview of iris heterochromia

Heterochromia (iris heterochromia; English heterochromia)

Two types of iris heterochromia

People or animals with this condition may have one of the following situations:
The iris of his two eyes have different colors (binocular heterochromia; Binocular Heterochromia);
His eyes may have more than one color in the same iris (Uniocular Heterochromia or Sectoral Heterochromia).
For a person or animal with two eyes with different irises, we will also say that he / it has a two-color pupil or a gold and silver pupil. For example: maybe one eye is blue but the other is grey.

Causes of heterochromia

The appearance of iris heterochromia can be divided into two aspects, congenital and acquired.
Congenitally, it is mainly that the iris color of the two eyes is different, which may be genetically related. Because the color of the eye iris is genetically affected, if one of the parents of the offspring has blue eyes and the other has gray eyes, the offspring of the two offspring may have a pair of blue eyes or a pair of gray eyes , But it is also possible that the iris on one side of the eye is blue and the other side is gray. This may be related to Waardenburg Syndrome or Piebald Syndrome.
The acquired condition may be due to the suffering of Horner Syndrome or iris trichomatitis, causing damage to the iris and atrophy.
It may also be caused by a lack of iris pigment, or it may be related to genes.

Note: About David Bowie's pupils
Gold and silver eyed pupil
This title was coined by the Taiwanese to describe David Bowie's eyes. His eyes looked dramatic, one eye was always brown, and the other was blue-green, and it would change as the light changed-compared to the artificial ghost eyes of Marilyn Manson It's too unnatural. It is said that people with such eyes are the offspring of close relatives, and they are often unstable and dangerous. However, this statement has nothing to do with David Bowie.
At the age of 14, Bowie and his friend George Underwood fought for a girl who was jealous. As a result, Bowie's left eye was damaged, causing the pupil of the left eye to lose light. After that, the two eyes showed different colors because of different reflections of light.
