Identification of Optic Disc Elevation and the Crescent Sign Using Point-of-Care Ocular Ultrasound in Children

ABSTRACTPoint-of-care ocular ultrasound has been used to detect papilledema. In previous studies, investigators have evaluated only optic nerve sheath diameter as a screen for increased intracranial pressure. In this series of 4 children, we demonstrate 2 additional optic nerve abnormalities using point-of-care ocular ultrasoundoptic disc elevation and the crescent sign. Assessing the optic nerve for each of these 3 findings may assist the examiner in detecting papilledema.
