This group is for people who have the eye condition called Coloboma. We are not doctors, or genetic counselors, we are just a group of people, from around the world, who share an eye condition. Information found here should not be used for the diagnosis or treatment of any eye condition. A licensed Ophthalmologist should be consulted for diagnosis and treatment.

Coloboma is a Greek word, which means mutilation. People with Coloboma are missing a portion of the structure of the eye. The human eye develops between the fourth and fifteenth week of pregnancy. As the eye starts to develop, a gap opens on the underside of each eye bud. This gap provides a way for the developing eye to be nourished. This gap, called the optic fissure, has to close before the eye is fully developed. Coloboma is the incomplete closer of the optic fissure. Gaps can occur in the eye lid, iris, ciliary body, lens, retina, macula, choroid and optic disc. It can cause from mild to sever vision loss. Coloboma occurs in about 1 in 10,000 births.
