title: Detection of drusen of the optic disc in children by B-scan ultrasonography.
abstract: Distinguishing between anomalous elevation of the optic disc caused by buried drusen and true papilledema can often be clinically difficult. In a prospective study of 18 children with drusen of the optic disc B-scan ultrasonography with a lowered sensitivity was found to be useful in the uncooperative child. A rational approach to the investigation of elevation of the optic disc in children is offered.
