What is Heterochromia?
Heterochromia is a genetic anomaly in which the individual has a different tonality in their eyes, specifically in the iris, making one eye a different color from the other. This can often be seen in dogs and cats, it is believed that only 6 out of every thousand people have this anomaly.
Different eyes can also be caused by a disease, for this reason a person needs to undergo medical tests and procedures. Another way to achieve a different color in a single eye is by using lenses.
Despite the name syndrome or diseases, not all of them have real problems in the person's life, but some need to be taken care of. Here is a list of possible causes of Heterochromia:
- Bloch-Sulzberger syndrome
- Horner's syndrome
- Parry-Romberg syndrome
- Sturge-Weber syndrome
- Waardenburg syndrome
- iris ectropion syndrome
- pigment dispersion syndrome
- Posner-Schlossman Syndrome
- von Recklinghausen's disease
- Bourneville Disease
- Hirschsprung's Disease
- Diabetes
- eye surgery
- Glaucoma
- eye injury
- eye swelling
- iris tumors
Research suggests that most cases of heterochromia in humans are benign and occur without any underlying abnormality.
Types of Heterochromia
There are three types of Heterochromia, they are Sectoral, Central and Complete. Understand a little below:
Sectoral heterochromia
Sectoral Heterochromia is the most common of the three types. It is considered sectoral when the same iris has more than one color, it can be just reflections or one side of the iris differs from the other; one of the colors is always dominant.
It can also be called heterochromia iridum and can appear in both or just one eye. In Japanese it is called kousaiishokushou [虹彩異色症]. Alexander the Third, King of Macedon, is believed to have had some form of heterochromia.
central heterochromia
Central heterochromia consists of the presence of two or more circles in the iris, each one of a color, this type of anomaly is known as "Cat's Eye".
When heterochromia is caused by a genetic abnormality, the carrier's eyes are more likely to be blue and brown, and when it is caused by the syndrome, the carrier is more likely to have green and brown eyes.
complete heterochromia
As the name suggests, this is complete heterochromia that changes the color of the entire eye or when the eye is a completely different or opposite color from the other. This is the rarest type of heterochromia in existence.
Heterochromia in Japan
The breed of cats called Mi-Ke, a kind of lucky cat, often has eyes of different colors, nicknamed gold and silver eyes. These cats often have a yellow and blue eye, but some may accompany hearing disorders on the blue eye side.
There are 2 famous Japanese with Heterochromia, first let's mention Akira Hashimoto a Japanese journalist and critic who passed away in 2017, a former student of Emperor Akihito. He acquired these colors in his eyes because of some injuries.
We also have the actress and singer Megumi Okuna who participated in many dramas, his case is congenital (since he was a baby), but it is not very perceptive from afar. There are probably other unknown Japanese people with different colored eyes.
In creative works from subcultures such as anime, manga, and games, characters are sometimes given the physical characteristics of iridescent heterochromia, or a similar physical appearance where the iris color is different in the left and right eyes.
Although rare in real humans, such character configurations tend to be frequently favoured, and have appeared in many works in recent years. In 2001 it was estimated that one in five works had a character with a different eye color.
