Increase in optic nerve sheath diameter predicts early cerebral involvement in fat embolism syndrome

Chinese Journal of Traumatology, 2021
Early diagnosis of cerebral fat embolism in a patient with contradiction to MRI is challenging. Here we report an interesting case, where the raised optic nerve sheath diameter helped us to predict the early cerebral involvement with fat emboli in a left

Neuromorphic Devices and Computing for Sensing, Memory, and Control

Advanced Science, EarlyView.
This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

Morphometric analysis of myelinated fibre composition in the optic nerve of adult C57BL and CBA strain mice and (C57BL x CBA) F1 hybrid:a comparison of interstrain variation [PDF]

, 1995
In a study involving 50 optic nerves isolated from 3 different strains of adult male mice, C57BL, CBA and (C57BL x CBA) F1 hybrids, and from adult female CBA strain mice, we observed that the mouse had a lower mean total myelinated nerve fibre count than

Evaluation of commercially available point-of-care ultrasound for automated optic nerve sheath measurement

The Ultrasound Journal, 2023
Background Measurement of the optic nerve sheath diameter (ONSD) via ultrasonography has been proposed as a non-invasive metric of intracranial pressure that may be employed during in-field patient triage.

Admission optic nerve sheath diameter and optic nerve sheath diameter/eyeball transverse diameter ratio as prognostic markers in stroke

Journal of Neurosciences in Rural Practice
Objectives: Raised intracranial pressure (ICP) is a major determinant of secondary injury in acute stroke. Optic nerve sheath diameter (ONSD), measurable on computed tomography and magnetic resonance imaging, may provide a simple non-invasive surrogate of ICP, but data from Indian stroke populations are limited.

Optic nerve sheath diameter assessment by neurosonology

Journal of Neuroimaging, 2021
Background and Purpose Reported cutoff values of the optic nerve sheath diameter (ONSD) for the diagnosis of elevated intracranial pressure (ICP) are inconsistent. This hampers ONSD as a possible noninvasive bedside monitoring tool for ICP. Because the influence of methodological differences on variations in cutoff values is unknown, we performed a ...
