What is heterochromy?
Heterochromy is an anatomical condition in which the iris in the eyes of a human or animal are two different colors. This condition can also occur in hair or skin color, but is the most common in the eyes. Heterochromy occurs when a person or animal has too much or too little composed melanin in the body. Melanin is a compound found in plants and animals that create a pigment. Different colored eyes may also occur due to bleeding or foreign objects in the eye, glaucoma or some drugs for treatment or neurofibromatosis. Even a slight inflammation in one eye can cause this condition.
When it affects the eyes, this condition can also be called heterochromy Iridis or heterochromy Iridum. Eyes can either have complete heterochromy, which means that each eye is different color or partial or sectoral heterochromy, which means there are two different colors of one iris. Complete heterochromy is more common diversity. Partial or sectoral version usually comes from inherited afterDímek, such as Waardenburg's syndrome and Hirschsprung's disease.
complete heterochromy is the most common in cats, although it can occur in humans. Most often the cat has a "odd eye" one blue eye and one normal eye. It also occurs in dogs, especially in Siberian goose and Dalmatian breeds, some horses, cattle, water buffaloes and certain ferrets. Partial heterochromy is most common in dogs from specific breeds, including Border Collie and Australian Shepherd.
Central heterochromy is when the central pupillary part of the iris is a different color than the middle peripheral or ciliary part, which forms the central "ring" around the pupil of the eye. This type is most common in irises that contain low levels of melanin. The real color is actually an outer ring, while the central ring depicts a color affected by heterochromy.
Medical Council from a healthcare provider should be sought if eachThe person notices changes in one eye. To determine the basic problem, it will need a complete eye examination and a report of any other symptoms. If a child has two different colored eyes, a pediatrician should be consulted, who is likely to want a child to see an ophthalmologist.
