Iris Coloboma
Coloboma of the iris arises from failed or incomplete closure of the embryonic fissure during development. This process occurs on day 33 of gestation and allows for pressurization of the globe.
The physical exam may reveal obvious defects in the iris and are typically seen at or soon after birth.
There is no cure for a coloboma, and treatment varies depending on the type. People with an iris coloboma may wear coloured contact lenses to make the iris appear round. Surgery can also correct the appearance of the iris.
