Multicenter Study
Distal enlargement of the optic nerve sheath in the hyperacute stage of intracerebral haemorrhage.
Optic nerve sheath diameter (ONSD) enlargement is detectable in patients with increased intracranial pressure. The aim was to detect an enlargement of the ONSD using optic nerve sonography in patients with acute intracerebral haemorrhage (ICH) within 6 h of the onset of symptoms. ⋯ Sonographically measured enlargement of the ONSD may already be detectable in the hyperacute stage of increased intracranial pressure.
