Central heterochromia, blue with brown. Central heterochromia is also an eye condition where there are two colors in the same iris; but the arrangement is concentric, rather than sectoral. The central (pupillary) zone of the iris is a different color than the mid-peripheral (ciliary) zone. Central heterochromia is more noticeable in irises ...
Heterochromia (heterochromia iridum or heterochromia iridis) is an eye condition in which one iris is a different color from the other (complete heterochromia), or where a part of one iris is a different color from the remainder (partial heterochromia or sectoral heterochromia).
Type 1 is characterised by congenital sensorineural hearing loss, pigmentary deficiencies of the hair such as a white lock of hair in the front-centre of the head or premature greying, pigmentary deficiencies of the eyes such as different-coloured eyes (complete heterochromia iridum), multiple colours in an eye (sectoral heterochromia iridum) or brilliant blue eyes, patches of skin ...
Most cases of heterochromia are the result of genetics, though sometimes, trauma or injury to the eye can disrupt the normal development of melanin in the iris—leading to changes in eye color.
Abnormal clumping of melanosomes does occur in disease and may lead to irreversible changes in iris color (see heterochromia, below). Colors other than brown or black are due to selective reflection and absorption from the other stromal components. Sometimes, lipofuscin, a yellow "wear and tear" pigment, also enters into the visible eye color ...
This is a list of notable people who have been documented as having heterochromia iridis, a condition when the irises have different colours. People who are frequently mistakenly thought to have heterochromia are not included, but may be listed in the Notes section.
With most eye colors, the amount of melanin is consistent across the entire iris—the more melanin, the darker the eye will appear. With hazel eyes, however, varying amounts of melanin exist in ...
