Better prognostic value with combined optic nerve sheath diameter and grey-to-white matter ratio on initial brain computed tomography in post-cardiac arrest patients.
AIM We aimed to evaluate the prognostic value of optic nerve sheath diameter (ONSD) and grey-to-white matter (GWR) either alone or in combination in patients treated with targeted temperature management (TTM) after cardiac arrest (CA). METHODS We conducted a retrospective single centre study of post cardiac arrest patients treated with TTM. ONSD and GWR on brain computed tomography (CT) was m...
متن کاملEffect of scuba-diving on optic nerve and sheath diameters
Background :There is not any data available about the effect of high bar pressure condition on intracranial pressure. In this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated. Methods : Twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. Only one perso...
متن کاملUltrasound measurement of optic nerve diameter and optic nerve sheath diameter in healthy Chinese adults
BACKGROUND Measurement of optic nerve sheath diameter (ONSD) is a fast and non-invasive method in detecting elevated intracranial pressure. However, the reported normal range of ONSD was inconsistent. The objective of the study was to determine the normal range of ONSD in healthy Chinese adults. METHODS Eyeball transverse diameter (ETD), optic nerve diameter (OND), and ONSD were measured by u...
متن کاملA novel method of detecting raised intracranial pressure from head computed tomography using optic nerve sheath diameter
Introduction Raised intracranial pressure (ICP) can cause secondary brain injury, which is associated with severe disability and mortality [1]. Invasive ICP monitoring has been linked to increased mortality [2]. Sekhon, et al. [3] demonstrated a strong correlation between optic nerve sheath diameter (ONSD) on CT scan and ICP, with the potential to use this non-invasive method to detect raised ICP.
متن کاملCoronal Axis Measurement of the Optic Nerve Sheath Diameter.
OBJECTIVES The true optic nerve sheath diameter cutoff value for detecting elevated intracranial pressure is variable. The variability may stem from the technique used to acquire sonographic measurements of the optic nerve sheath diameter as well as sonographic artifacts inherent to the technique. The purpose of this study was to compare the traditional visual axis technique to an infraorbital ...
