Heterochromia

Different colours in the two eyes, or two colours within one iris.

Also: heterochromia iridum, odd eyes

Heterochromia means a difference in iris colour. In complete heterochromia the two eyes are different colours; in sectoral heterochromia a wedge of one iris differs; in central heterochromia a ring near the pupil is a different shade. Most people with it are born that way and it causes no trouble. It is uncommon in people but well known in some cats and dogs. A change in eye colour in adulthood is a reason to see a doctor.
