Anomalous optic disc elevation associated with ultrasonographic evidence of increased subarachnoid fluid.
The presence of increased subarachnoid fluid around the optic nerve as measured by ultrasound has been shown to be associated with elevated intracranial pressure, as well as a number of other conditions. This finding has proved useful for distinguishing optic disc elevation secondary to papilledema from disc elevation attributable to other causes. This report describes a patient with anomalous optic disc elevation and increased subarachnoid fluid around the optic nerve.
