Ultrasound 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 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 ...
متن کاملTransorbital ultrasound measurement of optic nerve sheath diameter in normal rabbits
Objective: This study aimed to investigate the feasibility and reliability of transorbital ultrasound (TOUS) measurement of optic nerve sheath diameter (ONSD) in healthy rabbits and evaluate the influence of body weight and head circumference on the ONSD biometry. Methods: TOUS was performed to measure the ONSD 3 mm behind the optic disk in 31 adult male New Zealand White rabbits independently ...
متن کاملAccuracy of optic nerve sheath diameter measurement by emergency physicians using bedside ultrasound.
BACKGROUND Ultrasound (US) measurement of the optic nerve sheath diameter (ONSD) has been utilized as an indirect assessment of intracranial pressure. It is usually performed by trained ultrasonographers. OBJECTIVES To evaluate whether or not emergency physicians (EP) are capable of measuring the ONSD accurately by US. MATERIALS AND METHODS A retrospective measurement of ONSD was conducted ...
متن کاملA unique method for estimating the reliability learning curve of optic nerve sheath diameter ultrasound measurement
BACKGROUND Optic nerve sheath diameter (ONSD) measurement using ultrasound has been proposed as a rapid, non-invasive, point of care technique to estimate intra-cranial pressure (ICP). Ultrasonic measurement of the optic nerve sheath can be quite challenging and there is limited literature surrounding learning curves for this technique. We attempted to develop a method to estimate the reliabili...
