What is heterochromia? Heterochromia is when you have eyes that are different colors, or you have color variations within the same eye. Eye colors range from light blue or gray to dark brown. Your iris is the part of your eye that's colorful.
Usually, both eyes match in color. A person with differently colored eyes or eyes that are more than one color has heterochromia. about the symptoms, types, risk factors, causes, diagnosis, and treatment.
Heterochromia of the eye is called heterochromia iridum (heterochromia between the two eyes) or heterochromia iridis (heterochromia within one eye). It can be complete, sectoral, or central. In complete heterochromia, one iris is a different color from the other.
In sectoral heterochromia, part of one iris is a different color from its remainder. In central heterochromia, there is a ring. Heterochromia describes when a person's eyes aren't the same color.
Find out about the different types of heterochromia and what causes it to occur. Ever looked closely into someone's eyes and noticed a vibrant ring of color encircling the pupil, distinct from the rest of the iris? That eye-catching trait is called central heterochromia, and it's more common than you might think. Here are the main types: Central heterochromia.
A different color around the pupil compared to the outer iris (usually in both eyes). Complete heterochromia. One iris is a completely different color from the other (like one brown eye and one blue).
Segmental heterochromia. A section or wedge of one iris is a different color from the rest of. Some conditions can drastically change how one's eyes look, such as albinism, anisocoria, and heterochromia.
These are rare events, but they provide important new information on the complex and varied ancestral human genetic makeup of eye color. Heterochromia, in which a person has two different-coloured eyes, is one such condition. Learn the definition of central heterochromia, a condition that involves eye color, and why it happens.
What is heterochromia and what causes it? Dive into our comprehensive guide for different-colored eyes, and find everything you need to know. The brown allele is dominant over the green allele, and both are dominant over the blue allele. [3] Since many other genes play a role as well, this occasionally creates unexpected iris color.
Congenital heterochromia can be inherited, and autosomal dominant inheritance has been reported. [4].
