Interest of imaging in the early diagnosis of unilateral chorio-retinal coloboma

Ocular coloboma is a congenital malformation occurring around the sixth week of embryonic life. It is due to an abnormality of development of the lens, iris, choroid or retina due to lack of closure of the embryonic cleft. The involvement is variable ranging from a simple irian notch to the absence of retinal tissue on much of the lower retina. It can also include the disc. It is often bilateral and associated with microphthalmia. We report the case of unilateral chorioretinal coloboma associated with microphthalmia diagnosed early with imaging.
