ABSTRACT
Coloboma of the eyelids, lens, iris, ciliary body, choroid, retina and/or optic nerve arise from failed or incomplete closure of the embryonic fi ssure during development. A ocular colobomas may extend from the pupillary frill of the iris anteriorly to the optic disc posteriorly. Th e ocular colobomata may be associated with many systemic and ocular congenital anomalies. A coloboma can occur in one eye (unilateral) or both eyes (bilateral). People with coloboma may have no vision problems or may be blind, depending on severity. We report a case of unilateral typical coloboma of the iris, retina, and choroid associated with heterochromia of the iris.
