What is central heterochromia (2)?

(2) This may occur between the two eyes or within one eye. Central heterochromia, in particular, is characterized by differences in pigmentation in the same eyes. Central heterochromia causes a color abnormality that looks like it stems from the pupil at the center of the eyes, like cat eyes.

What does Central heterochromia look like?

Central Heterochromia. This type of heterochromia is characterized by a ring around the pupil with a different pigmentation from the rest of the iris. The ring is usually located at the centre of the iris closest to the pupil. It is sometimes very easy to confuse central heterochromia with the hazel eye color.

What is segmental heterochromia?

Segmental heterochromia is also known as heterochromia iridum, sectoral heterochromia, or partial heterochromia. Again, it occurs when different areas of the same iris vary in pigment. (3) For example, someone might have blue eyes with bits of brown or brown eyes with a patch of green.

What is heterochromia?

Let’s get started. The color of the eyes (in any species) is determined by a substance called melanin (which is a pigment), more specifically, either too much melanin or a lack of it.
