This eye condition can affect one or both eyes. It usually resembles an irregular patch on your iris and doesn’t form a ring around your pupil. It is the condition where part of one iris has a different type of color from the remaining areas of that iris. This is also referred to as partial heterochromia. For instance, one eye may be blue and the other eye may be brown. Here is how it differs from complete and sectoral heterochromia: Complete HeterochromiaĬomplete heterochromia is the condition where one iris has a different color than the other iris. But the arrangement of the colors is concentric with the central zone of the iris being a separate color from the mid- to peripheral zone. In central heterochromia, an iris shows two colors. Central heterochromia is one of three primary main types of heterochromia that include complete heterochromia, or partial heterochromia. Heterochromia refers to a variation in the colors of the iris. How Is Central Heterochromia Different from Other Forms of Heterochromia? Latanoprost is associated with iris color changes in some patients undergoing long-term latanoprost therapy. Acquired heterochromia can be caused by:Īlso, a medication used to treat glaucoma, latanoprost, may cause heterochromia. The condition is then termed acquired heterochromia and is less common than the genetic type. Other cases of central heterochromia develop later in life, triggered by an injury, illness or medication. Some cases of congenital heterochromia are linked to the following syndromes and diseases: Central heterochromia can occur without any underlying abnormality and is typically benign.Īccording to the Genetic and Rare Diseases Information Center, many heterochromia cases occur sporadically in individuals with no familial history of the eye condition. When this is the case, the condition is called congenital heterochromia. Most cases of central heterochromia stem from genetics and are present from birth. Central Heterochromia is known to be more common than complete Heterochromia. In the United States, fewer than 200,000 people are affected by complete heterochromia, where the color of one iris is different from the other. The exact prevalence of central heterochromia is not known since the condition itself rarely requires medical attention and is thus difficult to document. This condition usually affects both eyes. What Is Central Heterochromia?Ĭentral heterochromia is a condition in which the inner ring of your iris (the section closest to your pupil) has a different coloration from the outer ring of your iris (area along the edge of your iris). The condition is linked to a small variety of illnesses but is usually not serious. Most people who have central heterochromia get it from a family history, but there are sporadic cases of non-genetic causation. Central heterochromia describes an uncommon condition in which the inner and outer rings of the iris are different colors.
