Heterochromia
Heterochromia
Heterochromia (pronunciation: /ˌhɛtəroʊkroʊˈmiːə/) is a condition in which the iris of one eye is a different color than the iris of the other eye. The term is derived from the Greek words "heteros" meaning different and "chroma" meaning color.
Etymology
The term 'Heterochromia' is derived from the Ancient Greek words 'heteros' (ἕτερος), meaning 'different', and 'chroma' (χρῶμα), meaning 'color'.
Types of Heterochromia
Heterochromia can be classified into three types:
- Complete Heterochromia: This is when one iris is a completely different color from the other.
- Partial Heterochromia: This is when part of one iris is a different color from its remainder.
- Central Heterochromia: This is when there are spikes of different colors radiating from the pupil.
Causes
Heterochromia is usually an inherited trait, although it may be caused by injury or disease. It can also be a result of a condition called Horner's syndrome, or due to the use of certain medications.
