Eyelid Coloboma

Abstract
The term coloboma derives from a Greek word “koloboma,” which means mutilated or curtailed or a hole or a defect in tissue. An eyelid coloboma is a congenital full-thickness defect of the eyelid margin seen in about 1 in 10000 births and may also involve different structures of the eye: eyelids, iris, lens, ciliary body, choroid, retina, or optic nerve.[1]  Congenital eyelid coloboma is can be unilateral or bilateral, involving one or all four lids. The defect may vary from a small marginal notch to a full-thickness absence of the entire eyelid margin involving one third to half of the eyelid. Usually, the upper eyelid is commonly affected, and the most common site is the junction between the medial and middle third of the upper eyelid. Eyelid colobomas represent an incomplete form of cryptophthalmos. Cryptophthalmos is a congenital condition in which there is a failure of differentiation of eyelid structures, and the skin passes uninterrupted from the forehead to the cheek.
