Is this combined with diseases?
Iris heterochromia can, but does not have to occur as part of a disease. Iris heterochromia, which is congenital and does not present with any other symptoms, is usually a completely harmless freak of nature. However, iris heterochromia can also occur in some genetic diseases such as Waardenburg syndrome.
Here it is often combined with hearing loss and other symptoms. A newly occurring iris heterochromia is almost always a symptom of a disease. It should therefore be examined by an ophthalmologist. This is of particular importance if additional symptoms such as pain, pupil imbalance or visual disturbances occur.
