Heterochromia

Heterochromia is a color difference in the color of the iris of the eye. Usually it is congenital, but sometimes it can develop after suffering inflammation of the iris.

In the presence of heterochromic irises (heterochromia iridis), the irises of both eyes are different from each other. In the case of heterochromic iris (heterochromia iridum), one part of the iris of the eye is different in color from the other part.

Heterochromia can be complete, when the irises of the eyes have completely different colors, and partial, when there are areas with different colors.

The causes of heterochromia can be congenital (genetic mutations, developmental disorders) and acquired (inflammation, trauma, tumors). Sometimes heterochromia is associated with systemic diseases.

In some animals (such as cats), heterochromia is quite common. In humans, this is a rare phenomenon that gives a unique appearance. Famous people with heterochromia: David Bowie, Kate Bosworth, Alexander Pushkin, Jane Seymour, Mila Kunis.

Heterochromia: when the eyes speak different languages

Heterochromia is a condition in which the color of the iris varies between the right and left eyes, or even within the same eye. This feature can appear in humans and animals, and it can attract the attention of others. In this article we will take a closer look at heterochromia and its causes.

Heterochromia can be congenital or acquired. In the first case, the difference in the color of the iris is due to hereditary factors. The second case is associated with inflammation of the iris, injury or other diseases.

There are two main types of heterochromia: heterochromia iris (heterochromia iridis) and heterochromia iridum. In iris heterochromia, the irises of both eyes are different from each other. With heterochromia of the iris, one part of the iris is a different color from the other.

Heterochromia can appear in various shades and color combinations. Combinations of blue and brown colors are often found. In some people, heterochromia can be so mild that it is almost impossible to notice, while in others it can be so strong that the eyes appear two-colored.

Although heterochromia may only be a cosmetic defect, it can sometimes indicate the presence of other diseases. For example, heterochromia can be a symptom of glaucoma, inflammation of the eyeball, or other eye diseases. Therefore, if you find signs of heterochromia in yourself or your child, you should consult a doctor to diagnose and identify the causes of this condition.

In conclusion, heterochromia is an interesting feature that can be either congenital or acquired. Although it may simply be a cosmetic defect, in some cases it may indicate the presence of other medical conditions. If you or your child have heterochromia, consult your doctor for a more detailed examination and diagnosis.

Eyes. What first comes to our mind when it comes to human eyes? Hue, or iris, is the colored film through which we see. Our retina is visible behind it. Healthy grey, greenish or blue are common eye images we often see on people. But this is not the final verdict, there are eyes of other colors and formats. One of these options is heterochromia.

Heterochromia of the iris is divided into several types. There are cases in which the iris of the eye is surrounded by a black pigment ring. This is inherent in such types of heterochromia as aniridia and endochromia; There are cases. in which the lighter or darker color of the iris layer of different eyes merges together in the shape of a ring. It can be seen in the transient form of heterochromia. The ring shape can be based on blue, brown or honey color; If at least one color in the eye wallpaper is noticeably brighter than the second, then the type of heterochromia will be called a mixed form. There is also albinism - complete, diffuse or partial; The merging of the colors of the irises into both eyes is called the same type of heterochrony.

Heterochromia is a term used to describe the coincidence of two or more iris colors in one eye. Instead of the generally accepted medical term “heterochromia,” the term “eye color” is often used in this matter, but this is a distortion of reality, since eye color is a concept, not a fact[1], which depends on both genotype and lighting. Heterochromia has a specific scientific term, aniridia, which refers to abnormal pigmentation of the iris [2].

In another sense, heterochromia is a superficial difference in the color of the iris or iris tissues in the same eye. It is found in the animal world, for example among snakes. In human origin it is considered as a variant of the norm. Each of the eyes becomes distinctly colored in different colors and although the rest of the organs are the same color, each scatter may differ in the size of the pupils.

There is a medical concept of heterochromia of the pupils, that is, a difference in the pigmentation of the pupillary zone of the iris in each of the two eyes, the cause of which is most often unknown; there are cases of an acquired nature of this phenomenon. Light shining into the pupil over different periods of time changes the radiation density and it looks different colors under the same lighting. Also among reptiles there are species with multi-colored variations of the iris, including a mutation of two copies in one body, combining colors from different areas of the eyeball.

Color variations in the iris are caused by melanin pigmentation. The difference lies precisely in the difference in the amount of its concentration in different areas of the eye, hence the different colors of the colors in the eyes. The suffix in the term “ano”, which means “unequal”, indicates the reason for the origin of the color of the iris - the pigment is located unequally. The term color difference, which distorts the real state of things regarding the shade of the eyes, can lead to some kind of inferiority of the individual (negative connotation), despite the fact that eyes with different shades are in many ways a beautiful and original manifestation of the genetic inheritance of the body. Moreover, knowledge of any variety of iris color shows the character and characteristics of a person, awareness of preferences or physical anomalies associated with them.
