Heterochromie

Heterochromia is a condition characterized by the presence of two differently colored irises within the same eye. This condition can be congenital, meaning it is present at birth, or it can develop later in life. The most common form of heterochromia is congenital heterochromia, which is usually due to a difference in the amount of melanin pigment in the iris. This can result from a genetic mutation or a developmental anomaly.

Heterochromia can be classified into several types based on the distribution of the different colors. In sectoral heterochromia, the iris is divided into two distinct areas of different colors. In asymmetric heterochromia, one side of the iris is a different color from the other. In heterochromia iridis, the entire iris is a different color from the surrounding tissue.

Heterochromia can be associated with other conditions, such as iris coloboma, a condition where there is a defect in the iris, or iris heterochromia syndrome, a genetic disorder that can affect multiple systems in the body. It can also be a sign of other underlying conditions, such as albinism or certain types of cancer.

Heterochromia is typically a cosmetic condition and does not usually affect vision. However, in some cases, it can be associated with other medical conditions that may require treatment. If you or someone else has heterochromia and is experiencing other symptoms, it is important to consult with a healthcare professional for proper evaluation and treatment.
