Coloboma is a congenital anomaly characterized by a defect in one or more structures of the eye. It results from a failure in the closure of the colobomatous fissure, which typically occurs between the 5th and 7th week of embryonic development. We present the case of a 19-year-old patient from a non-consanguineous marriage, with no notable pathological history, who consulted for a progressive decrease in bilateral visual acuity. Examination with a slit lamp and funduscopy revealed bilateral iris and chorioretinal coloboma in both eyes. A thorough physical examination was performed to rule out other associated malformations, and it returned normal. Regular ophthalmological monitoring is necessary to detect any risk of retinal detachment, the main complication associated with coloboma. It is also essential to evaluate the possibility of systemic involvement, which can have serious implications for overall prognosis.
