    What Is Heterochromia?

    Heterochromia is when a person’s irises are different colors. There are a few kinds of heterochromia. Complete heterochromia is when one iris is a different color than the other. When part of one iris is a different color than the rest of it, this is called partial heterochromia. Central heterochromia is when there is an inner ring that is a different color than the outer area of the iris.

    But what causes heterochromia and should people with the condition be concerned?

    Heterochromia Diagnosis and Treatment

    If your infant has heterochromia, he or she should be examined by an ophthalmologist. The ophthalmologist will confirm the appearance of heterochromia and look for any underlying causes. In most cases, there will be no concerning disease or condition causing the eye color variation. However, it is important to rule out these conditions.

    If you get heterochromia as an adult or it changes in appearance, see your ophthalmologist. He or she can perform a detailed eye exam to rule out any underlying causes and come up with a treatment plan if necessary.

    Treatment for heterochromia focuses on treating any underlying causes for the condition. If there are no other issues with the eyes, no treatment may be needed.
