Elevation in optic nerve sheath diameter due to the pneumoperitoneum and Trendelenburg is associated to postoperative nausea, vomiting and headache in patients undergoing laparoscopic hysterectomy

, 2020
BACKGROUND: Optic nerve sheath diameter (ONSD) measurement with ultrasound has emerged as a simple, noninvasive and reliable surrogate of invasive intracranial pressure (ICP) measurement.

Optic nerve sheath diameter asymmetry in healthy subjects and patients with intracranial hypertension [PDF]

, 2019
Ultrasonography of the optic nerve sheath diameter (ONSD) is used for the non-invasive assessment of increased intracranial pressure (ICP). ONSD values are usually obtained by averaging the measurements of the two eyes, but asymmetric ONSD dilation is ...

Ultrasonographic assessment of optic nerve sheath diameter on the affected and unaffected sides as a predictor of clinical deterioration at discharge in patients with large hemispheric infarction

Frontiers in Neurology
Background and objectivesProgressive cerebral edema worsens prognosis in large hemispheric infarction (LHI). Ultrasonographic optic nerve sheath diameter (ONSD) measurement provides a non-invasive method for estimating intracranial pressure.

Ultrasonographic optic nerve sheath diameter for assessing the effect of pneumoperitoneum and Trendelenburg position on intracranial pressure during gynecologic surgery: a prospective observational study

Asian Journal of Surgery
Background: Previous studies have shown that pneumoperitoneum and the Trendelenburg position can increase intracranial pressure (ICP). The optic nerve sheath diameter (ONSD) measurement using ultrasound has emerged as a simple, noninvasive, and reliable ...

Transorbital ultrasound measurement of the optic nerve sheath diameter (ONSD) as a screening tool for raised intracranial pressure in an acute care setting in children

, 2016
Background: Acute care management of pediatric traumatic brain injury (TBI) can be challenging. Early and reliable diagnosis of intracranial pressure (ICP) in children following TBI is vital in optimizing outcome.

Correlation between optic nerve sheath diameter measured by bedside ultrasound and intracranial pressure in neurologically ill patients in a Chinese population

BMC Neurology
Background We assessed the correlation between optic nerve sheath diameter (ONSD) values measured by bedside ultrasound and intracranial pressure (ICP) changes among patients under neurocritical care and evaluated the diagnostic performance of ONSD for ...

Optic nerve sheath diameter (ONSD) in sovratentorial brain tumor surgery: an option for non invasive raised ICP detection and management. Preliminary results and feasibility assessment (06AP04-9)

, 2017
Background and Goal of Study: Increase in optic nerve sheath diameter (ONSD) in transorbital sonography has been proven to be able to non-invasively detect elevated intracranial pressure in different clinical scenarios. The aim of this study is to assess
