What is Heterochromia? 2 Different colored eyes


Heterochromia is the term used to refer 2 different-colored eyes

A person with central heterochromia has different colors in precisely the exact same eye. Complete heterochromia is if they have two different colored eyes.

Heterochromia of the eye results from variations in the concentration and distribution of melanin, the pigment that gives color to skin, hair, and eyes.

The word “heterochromia” is derived from ancient Greek in which “heteros” means different and “chroma” implies color. The status is also known as heterochromia iridis or heterochromia iridum.

Quick facts on central heterochromia:

  • Less than 200,000 people in the United States have heterochromia. Some types of heterochromia are common in dogs, cats, and horses.
  • There are 3 types of heterochromia of the eye.
  • An ophthalmologist can diagnose heterochromia and investigate why it has occurred.
  • Treatment for heterochromia is all about handling the underlying causes.

What determines eye color?

Eye color is a result of melanin deposits from the iris, which is the part of the eye responsible for dilating and constricting the student to control the amount of light that enters.

Blue eyes have small quantities of saliva while brownish eyes are full of melanin.

Iris color might not stay constant throughout an individual’s life. For instance, many babies are born with blue eyes that darken within the first 3 decades of life. This change happens as the melanin develops.

Uneven distribution of saliva contributes to central heterochromia and other types of heterochromia.


In most cases, symptoms are present from birth when the problem is called genetic heterochromia.

Research indicates that most instances of heterochromia in humans are benign and occur without any underlying abnormality.

According to the Genetic and Rare Diseases Information Center, most cases of heterochromia of the eye occur occasionally in people without a family history of the condition.

However, some cases of hereditary heterochromia are linked to diseases and syndromes, including:

  • Bloch-Sulzberger syndrome
  • Bourneville disease
  • Sturge-Weber syndrome
  • Waardenburg syndrome
  • Horner’s syndrome
  • Parry-Romberg syndrome

Causes of acquired heterochromia include:

Kinds of eye heterochromia:

The different types of heterochromia of the eye include:

Central heterochromia :

Normally, the outer ring of the iris is one color while the inner ring is another.

The ring often appears to have “spikes” of unique colors that radiate from the pupil or the black circle at the center of the iris. Eyes that have this pattern also known as “cat eyes.”

Central heterochromia will happen in irises that have reduced levels of saliva.

Complete heterochromia:

People with this illness have two different-colored eyes. For instance, they might have one blue eye and one brown eye.

Sectoral heterochromia:

In individuals with sectoral heterochromia, also referred to as partial heterochromia, one part of this iris is a different color from the rest.

Sectoral heterochromia often resembles an irregular place on the iris of their eye and does not form a ring around the student.

Identifying heterochromia:

Heterochromia of the eye is simple to recognize. The person will have two different colored eyes or color differences within one or both eyes.

Color differences could be slight and may only become evident under specific lighting conditions or in photographs.

Aside from variations in eye color, there are typically no additional symptoms and signs of heterochromia.

But if a medical condition or trauma is responsible for the heterochromia, other symptoms and signs might be present.


Most cases of central heterochromia are benign. They are not connected to any medical conditions which affect vision or to any serious complications.

But a checkup is necessary to rule out other medical problems.

Individuals who acquire heterochromia and individuals whose genetic heterochromia changes in appearance should see an eye doctor.

An eye exam will ordinarily be necessary, and other tests, such as blood tests and chromosome studies, may be needed.

Treatments and Therapy:

According to the American Academy of Ophthalmology, if no other problems are present, treatment is not usually needed.

Colored contact lenses may be used for cosmetic reasons if a person who has this wants to alter how their eyes look.

Notable people with central heterochromia:

Several actors and public figures have kinds of heterochromia.

The actors Olivia Wilde, Idina Menzel, and Christopher Walken all have central heterochromia, where the inner ring of this iris is a different color from the outer ring.

Notable individuals with full heterochromia, where their two eyes are different colors, include:

  • Jane Seymour, celebrity
  • Alice Eve, actor
  • Max Scherzer, professional baseball player
  • Josh Henderson, actor
