Ocular sonography in pre-eclampsia: A simple technique to detect raised intracranial pressure?

In the past three decades, ultrasonographic images of the fibro-elastic sheath surrounding the optic nerve have become an important application of point-of-care ultrasound.1,2 There is a close correlation between optic nerve sheath diameter (ONSD) and intracranial pressure (ICP) 3 that is sufficiently dynamic to reflect pressure changes.4,5 The ONSD has been validated as an accurate screening tool to detect raised ICP in patients with idiopathic intracranial hypertension (IIH),6 traumatic brain injury (TBI),7,8 and spontaneous intracranial hemorrhage (ICH).
