摘要

We read with interest the study by Saffra et al. with reference to the sudden appearance of a retinochoroidal coloboma. The indentation between the margins of the optic cup is called the embryonic fissure, which extends from the rim of the optic cup near the lens to the distal optic stalk. To complete the entire wall of the globe, the 2 lips of the embryonic fissure meet and fuse. The term coloboma in medicine means the absence of part or all of a tissue. It may result from developmental disturbance, surgery, or injury. Typical isolated ocular coloboma is a congenital abnormality caused by defective closure of the embryonic fissure during weeks 5-7 of fetal life. Atypical colobomata appear in locations outside the region of the embryonic fissure.
