New marker for raised intracranial pressure
September 23rd, 2008
Magnetic resonance imaging (MRI) measurements of the thickness of the optic nerve sheath are a good marker for raised intracranial pressure (ICP). New research published in BioMed Central's open access journal Critical Care shows that a retro-bulbar optic nerve sheath diameter (ONSD) above 5.82mm predicts raised ICP in 90% of cases. The dural sheath surrounding the optic nerve communicates with the subarachnoid space and distends when ICP is elevated. Thomas Geeraerts, from Addenbrooke's Hospital, Cambridge, led a team who investigated whether MRI can be used to precisely measure the diameter of the optic nerve and its sheath. He said, "Raised ICP is frequent in...
