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.

With heterochromia, the iris in one eye may be a completely different color than the iris in your other eye. For example, you may have one blue eye and one brown eye. Of the common eye colors, brown eyes have the most melanin and blue eyes have the least.

Animals can have heterochromia, too. At some point, you've probably noticed a Siberian husky, Australian shepherd or border collie with two different-colored eyes. Along with other domestic animals, these dogs experience the same genetic phenomenon as humans.

Do you or does someone you know have different-colored eyes? When you meet someone with one blue and one brown eye, for example, it sometimes takes a minute to register why they may seem a little "not quite right." But then, when you look a little closer, you see how beautiful and unique this trait is. It's a rare phenomenon called heterochromia. So is it always DNA.

Dogs with one blue eye and one brown eye, also known as heterochromia, are truly unique and eye-catching creatures. This rare genetic trait occurs in many dog breeds, including Siberian Huskies, Australian Shepherds, and Border Collies, among others. Dogs with brown eyes have a large amount of melanin, while dogs with blue eyes have none in the stroma, the thickest part of the iris and the one that determines eye color.

Why do some dogs have one blue eye and one brown eye? Most of the time heterochromia is an inherited genetic occurrence, but occasionally it can be a result of an injury. It is characterized by the presence of two different colored eyes in a single individual, typically one blue and one brown. While this trait is not exclusive to dogs, it is particularly striking in them, often causing people to stop and stare.

But what is the significance of heterochromia in dogs? In dogs with complete heterochromia, one eye is blue while the other is brown. Less commonly, a dog can have two different colored eyes with flecks of another color, or one eye that is half one color and half another.
