Heterochromia da Barbara Bonanno BNNRRB Tramite Flickr: Heterochromia means "different (hetero-) colors (-chromia)." Usually the term is used to describe the condition where a person has different colored eyes — one blue eye and one green eye, for example. Other terms to describe different colored eyes are heterochromia iridis and heterochromia iridum. "Iridis" and "iridum" refer to the iris of the eye. The iris is the thin, circular structure that surrounds the pupil and contains the pigment melanin, which gives our eyes their distinctive color. The amount of melanin in the iris determines whether we have blue eyes, green eyes, hazel eyes or brown eyes. Blue eyes have the least amount of melanin in the iris; brown eyes have the most.

Benign heterochromia can give a person a captivating, even exotic, appearance. In fact, a number of celebrities — including Dan Aykroyd, Kate Bosworth, Henry Cavill, Alice Eve, Josh Henderson, Mila Kunis, Jane Seymour and Christopher Walken — have heterochromia. Heterochromia also occurs in animals. Breeds of dogs that commonly exhibit heterochromia include Siberian husky, Australian shepherd, border collie, collie, Shetland sheepdog, Welsh corgi, Great Dane, dachshund and Chihuahua. Such cat breeds include Turkish Van, Turkish angora, Japanese bobtail and sphynx. Often such "odd-eyed cats" have been bred specifically to have this feature. Types Of Heterochromia There are three types of heterochromia, based on where the different colors are located: 1. Complete heterochromia. This is where the iris of one eye is a completely different color than the iris of the other eye. 2. Partial heterochromia (or sectoral heterochromia). This is where only a portion (or sector) of the iris of one eye has a different color than the rest of the iris of that eye. Partial heterochromia can occur in one eye or both eyes. 3. Central heterochromia. In this type of heterochromia, the iris has a different color near the border of the pupil (compared with the color of the rest of the iris), with spikes of the central color radiating from the pupil toward the middle of the iris. Something that's often confused with heterochromia is a benign growth called an iris nevus. A pigmented nevus in the iris usually is round in shape and brown in color. Usually, only one iris nevus is present, but it's possible to have more. Though a person might argue that a brown iris nevus on a blue, green or hazel eye is a type of partial heterochromia, the term heterochromia usually isn't used when the cause of the color variation in the iris is a nevus. Iris nevi (plural of nevus) typically remain stable in size. If you have an iris nevus, your eye doctor usually will want to see you every six months (for a while, at least) to measure its size and rule out any growth that could indicate malignancy.
