Abstract Introduction The dural sheath surrounding the optic nerve communicates with the subarachnoid space and distends when intracranial pressure is elevated. Magnetic resonance imaging MRI is often performed in patients at risk for raised intracranial pressure ICP and can be used to measure precisely the diameter of optic nerve and its sheath. The objective of this study was to assess the relationship between optic nerve sheath diameter ONSD as measured using MRI and ICP. Methods We conducted a retrospective blinded analysis of brain MRI images in a .
