2020-02-14 00:00:00Z


Do you know someone with two different eye colors? Then, you probably have seen a person with heterochromia. It's a rare eye condition that only affects three out of every 500 people. It occurs for a number of reasons.

Genetics

In the vast majority of cases, heterochromia results from unique genetics, a non-malignant alteration that affects the pigment development in one or part of one iris.

Traumatic

Some people can develop heterochromia as an adverse result of injury or disease. Trauma can lead to change in the eye appearance. Disease such as glaucoma and diabetes can make the eyes appear differently than the other.

Types of Heterochromia

Heterochromia can be complete heterochromia, segmental, or central.

  • Complete Heterochromia (or heterochromia iridum) - each iris has different color
  • Segmental Heterochromia (heterochromia iridis) - there's a patch of a different color in one iris.
  • Central Heterochromia - two irises are matched but rings of a different color appears around the pupils.

If your heterochromia is not inborn but you notice one or both of your eye color suddenly change, it's highly recommended to see your eye doctor to assess your eye condition. If in case it is due to unaddressed adverse effect from an injury or a health condition, contact VisualEyes Optometrists.
