Heterochromia iridum
Heterochromia Iridum
Heterochromia iridum (pronounced: /ˌhɛtəroʊkroʊˈmiːə ˈɪrɪdəm/) is a medical condition characterized by differences in coloration of the iris, the colored part of the eye. This condition can be present at birth or develop over time due to genetic mosaicism, disease, or injury.
Etymology
The term "heterochromia iridum" is derived from the Greek words "heteros" (meaning different), "chroma" (meaning color), and "iridum" (referring to the iris of the eye).
Types
There are three types of heterochromia iridum:
- Complete heterochromia: This is when one iris is a different color from the other.
- Partial heterochromia: This is when part of one iris is a different color from the rest of it.
- Central heterochromia: This is when there are spikes of different colors radiating from the pupil.
Causes
Heterochromia iridum can be caused by a variety of factors, including genetic conditions such as Waardenburg syndrome and Sturge-Weber syndrome, diseases such as Horner's syndrome, and injuries to the eye.
