A unique model for ultrasound assessment of optic nerve sheath diameter.
BACKGROUND Ultrasonic assessment of optic nerve sheath diameter (ONSD) as a non-invasive measure of intracranial pressure (ICP) has been evaluated in the literature as a potential valid technique for rapid ICP estimation in the absence of invasive intracranial monitoring. The technique can be challenging to perform and little literature exists surrounding intra-operator variability. OBJECTIVE...
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...
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 کاملReproducibility and accuracy of optic nerve sheath diameter assessment using ultrasound compared to magnetic resonance imaging
BACKGROUND Quantification of the optic nerve sheath diameter (ONSD) by transbulbar sonography is a promising non-invasive technique for the detection of altered intracranial pressure. In order to establish this method as follow-up tool in diseases with intracranial hyper- or hypotension scan-rescan reproducibility and accuracy need to be systematically investigated. METHODS The right ONSD of ...
متن کاملOptic Nerve Sheath Diameter as a Bedside Assessment for Elevated Intracranial Pressure
A previously fit and healthy 26-year-old lady with no significant medical history presented with a two-month history of headaches. The headaches were prolonged, generalised, and unusually severe for the patient. Examination revealed papilloedema. The patient's optic nerve sheath diameter was measured 3 mm posterior to the globe and found to be 7.5 mm. The patient subsequently had computed tomog...
