The iris, which imparts the unique color of the human eye, is named after the Greek goddess Iris, meaning rainbow. In the embryology of the eye, iris development starts as early as the fourth week of gestation. The iris develops from both layers of the optic cup. The outer layer of the optic cup forms the pigmented layer of the iris, and the inner layer of the optic cup forms the non-pigmented layer of the iris. Neural crest cells give rise to the muscle layer of the iris. PAX6 is the key gene in eye development. The iris consists of an anterior limiting layer, a stromal layer, an anterior epithelial layer and a posterior pigmented epithelial layer. The anterior surface of the iris is divided into the pupillary zone and the ciliary zone by a zigzag line called the collarette.
