Iris Split in Half
The condition is known as sectoral heterochromia. It means that only a portion (or sector) of the iris of one eye has a different color than the rest of the iris of that eye. The condition is rare and typically doesn’t have any other significant symptoms or problems. But how captivating it is to look at! Also known as Heterochromia iridum. It may be part of a genetic condition. It may also be a growth (iris nevus) or occur after an eye injury. In rare instances it may be seen with other disorders.
Forgive me for bringing this up here, however, my corgi (dog) has this exact two colors and split down the middle. He has had it since at least 8 weeks when we adopted him.
