Spectral Doppler imaging of vessels in the optic nerve of children.
Elevation and blur of the optic disc margin with hyperemia and flame hemorrhages are classic features of papilledema that may not be present with mild elevations of the cerebral spinal fluid pressure. In children, the disc can be dramatically elevated with indistinct margins in pseudopapilledema. Children with equivocal disc features are sedated for neuroimaging and lumbar puncture to measure opening intracranial pressure.
