Central heterochromia - an inner ring is a different color than the rest of the iris. The concentration and distribution of melanin determine the eye color, specifically the color of the irises. The affected eye may be hyperpigmented (hyperchromic) or hypopigmented (hypochromic). Additionally, th...
Newborns’ eyes all look blue because it takes weeks for the genetically-designated amount of melanin to ‘color in’ their irises. Today’s scientists believe that two genes control eye color (not just one), and it ishow these genes interactthat provides the full range of colors in people...

an autosomal dominant disorder caused by mutations in the PAX3 gene, is characterized by pigmentary disturbances of the iris, hair and skin, as well as congenital sensorineural hearing loss. But two different eye colors tends to be an isolated finding, which adds to the seemingly endless and ...
(one 10-month-old and four 15-months-olds) or due to low quality of eye tracking because of their bright iris or failure to calibrate (two 10-month-olds and one 15-months-old). For all participants, their parents were provided with a brief explanation of the study and provided written...
