Eyelid coloboma

What it means

A short discontinuity of the margin of the lower or upper eyelid.

The lateral segment of the lower eyelid is most commonly involved. As the milder forms of this finding are clearly subjective and no boundary of subjective and objective is defined, the term is considered subjective. The term eyelid coloboma has been replaced because the word coloboma should be used only for defects at the site of fusion of embryologic structures, which is not the case here. Modifiers to designate the location of the cleft may be added, such as lower and lateral.
