This is iris melanoma. The iris is the colored part of the eye. It is made up of two layers. The outer “stroma” can be blue, hazel, green or brown. The back layer (the iris pigment epithelium) is always brown. Tumors can grow within and behind the iris. Though most iris tumors are cysts or nevi, malignant melanomas can also occur in the iris.
