BACKGROUND AND PURPOSE: "Congenital cavitary optic disk anomalies" is a term used to include optic disk pit (ODP), optic disk coloboma, and morning glory disk anomaly (MGDA). Imaging the radial peripapillary capillary (RPC) network in congenital optic disk anomalies with optical coherence tomography-angiography (OCTA) can shed light on its pathogenesis. This video describes the OCTA findings of optic nerve head and RPC network using the angio-disk mode in five cases of congenital cavitary optic disk anomalies. SYNOPSIS: The video presents characteristic RPC network alterations in two eyes of ODP, one eye of optic disk coloboma, and two eyes of noncontractile MGDA. HIGHLIGHTS: OCTA in ODP and coloboma shows absence of RPC microvascular network and a region of capillary dropout. This finding is in contrast to MGDA, where the microvascular network is dense. OCTA is an effective imaging modality to study vascular plexus and RPC and their alteration in congenital disk anomalies, which could provide information about the structural differences among them.
