Morning Glory Disc Anomaly with an ipsilateral Optic Nerve Glioma

Morning glory disc anomaly (MGDA) is a congenital disorder characterized by the funnel shape disc excavation with radiating retinal vessels. MGDA is sometimes associated with midline developmental or vascular malformations. On evaluation for visual function, MGDA and concurrent ipsilateral optic nerve enlargement were found. This case is to report a rare CNS association with MGDA and to alert the importance of systemic evaluation in congenital optic nerve anomalies.
