Description Coloboma literally means a "gap"-and can be used to describe any fissure, hole, or gap in the eye. The term most often is used to refer to a congenital gap in the disc, retina, the choroid, and the iris. Colobomas occur because the embryonic fissure fails to fuse. Since the fissure closure begins in what will become the inferior retina and continues up to the iris and pupil region including the optic nerve, colobomas are usually inferior to the disc. Colobomas can be of the optic nerve or retina - choroid complex. When they are of the optic nerve, they can mimic optic atrophy. If the coloboma extends to the pupil, pupillary colobomas can also be present. This person has bilateral pupillary colobomas -- gaps inferiorly of the pupil.
