Palpebral cleft or coloboma, unilateral – http://id.who.int/icd/entity/1369978989

This is a hole in one of the structures of the eye, such as the iris, retina, choroid or optic disc. The hole is present from birth and can be caused when a gap called the choroid fissure, which is present during early stages of prenatal development, fails to close up completely before a child is born. This diagnosis is occurring in one eye (unilateral).
