ABSTRACT Optic nerve aplasia (ONA) is a rare congenital anomaly with a limited number of published reports. A retrospective review was performed on seven patients with ONA seen during 2004–2017. Patient’s ocular and extraocular manifestations, imaging findings, and clinical course were described. Magnetic resonance imaging (MRI) showed anomalies of the optic chiasm and tracts and other central nervous system involvement. In conclusion, in addition to thorough ophthalmic examinations, MRI is important in evaluating and diagnosing ONA. The patients need to be monitored for both ocular and extraocular concerns.
