What is Heterochromia in medical sciences ? What are the symptoms of Heterochromia ?

The amount of melanin in the iris is what makes our eyes blue, green, brown or hazel. Most melanin is found in brown eyes, while the least melanin is in the iris of blue eyes. We can say that ‘Heterochromia’ occurs as a result of different concentration of excess or minorities in melanin distribution. Contrary to popular belief, ‘Heterochromia’ does not prevent vision because it is not a disease and does not pose a threat to our health unless it shows serious increases. Heterochromia is not only found in humans but also in animals.

The best known example is Van Cats, one eye blue and one green eye. “Heterochromia” is usually hereditary and congenital, but in some it can also manifest itself in the form of color changes in childhood. “Heterochromia” can occur for many reasons.

What are the types of Heterochromia ?

Full Heterochromia : In this case, the two eyes are completely different colors. It can occur as one eye is brown while the other is blue / green. Alice Eve’s eyes are examples of full heterochromia.

Fragmented Heterochromia : In this case, only part of the iris will be of a different color. You can also think of it as a different color stain on the eye. Jonathan Rhys Meyers is a celebrity with fragmented heterochromia.

Central Heterochromia : In this case, the central part of the iris will have a different color than the real color of the outer part of the eye. Generally, blue eyes can be observed as golden yellow in the middle. People with such eyes are often called cat eyes.

What does Heterochromia mean ?

Heterochromia is the difference in discoloration that can be observed in the eyes, but sometimes in the hair and skin. It is caused by a relatively high or low dispersion of melanin pigment, which is involved in any coloration in the body. The reason for this distribution difference is a mutation that occurs in autosomal chromosomes (usually in the 8th chromosome).

Heterochromia can also be completely (both eyes are different colors), or partially (one eye has two different colors).

What is Heterochromia iridum in medical sciences ?

Heterochromia iridum (heterochromia occurring in the eye) is often hereditary and does not cause any harm (neutral mutation).

However, in some cases, it can be acquired later and in this case it may be necessary to suspect some diseases. Among the cases described so far, diseases in which heterochromia has appeared as a symptom (symptom) include diseases such as glaucoma, incontinentia pigment, Parry-Romberg Syndrome, Neurofibromatosis, Chromosome 8 Trisomy, Eye Hemorrhage, Eye Damage.

What is Heterochromia in Anatomy ?

In anatomy, heterochromia is the presence of different colors. It is usually seen in the iris, but can sometimes be seen in the hair and skin. Heterochromia is the result of excess or deficiency of melanin (pigment). This can be inherited, or for reasons such as genetic mosaicism, chimerism, disease, and trauma.

There are three forms of the eye’s heterochromia (heterochromia iridis or heterochromia iridum; the common misnomer “heterochromia iridium” is not correct in Latin). In full heterochromia, the color of one iris differs from that of the other. Regional heterochromia is the presence of two different colors in different parts of an iris, and finally “central heterochromia” consists of the inner and outer colors being different colors.

Eye color, especially iris color, is determined by concentration and distribution of melanin. The affected eye can be hyperpigment (hyperchromic) or hypopigment (hypochromic). In humans, excessive melanin shows hyperplasia of iris tissues, just as in melanin deficiency.

What does Heterochromia mean in Anatomy ?

Heterochromia is primarily classified as genetic or acquired. Although this distinction has often been made between heterochromia, it affects one eye completely or partially (regional heterochromia), usually genetic (due to mosaicism or congenital) or subsequent, with darker or lighter iris, or some of it affected. Most cases of heterochromia are caused by a hereditary disease or syndrome, or because of a harm. Sometimes an eye can change color following certain diseases or injuries.

What does Heterochromia mean in medical sciences ?

Heterochromia is the difference in colour of the two irides or of different parts of the same iris. It is usually congenital but some cases are associated with some eye diseases such as cataract, corneal precipitates, glaucoma, iridocyclitis, iris melanoma or as a result of siderosis.
