Heterochromia iridis
Heterochromia iridis is a condition in which an individual has a variety of colors within a single iris. It is usually transmitted as a congenital (autosomal dominant) trait, but can result from pathologies such as or Piebaldism, pigment dispersion syndrome, Waardenburg syndrome, as well as injury to an eye, bleeding or inflammation within an eye, or eye tumors. It is much less common than the similar condition of heterochromia iridium, when a person has two different colours of separate iris.
Heterochromia iridium
Heterochromia Iridium is a similar condition in which an individual has two irises of different colors. This condition may occur by inheritance or by physical injury to the eye.
Many dogs and cats (particularly Siamese cats and husky dogs) have two differently coloured eyes, but it is less common in humans. One cause of heterochromia iridium is trauma to the eye, but it can also be a hereditary trait. Other causes of heterochromia iridium are certain types of diseases (e.g. Fuchs' heterochromic cyclitis, Horner's syndrome (with the affected side being lighter), pigment dispersion syndrome, Waardenburg syndrome) and the medication taken to treat them, such as topical latanoprost eyedrops when instilled unilaterally for the treatment of glaucoma.
Singer David Bowie is often described as an example, but in fact has two blue irises, with one pupil permanently dilated due to a childhood injury. By comparison, actress Kate Bosworth was born with one blue eye and one hazel eye, and actress Jane Seymour was born with one green eye and one brown eye, and are thus heterochromatic. Also, Mila Kunis shares this condition, with one green and the other blue. Singer Marilyn Manson mimics the condition with his trademark left eye contacts, but in fact, posesses two hazel eyes.
