Pediatric optic nerve and optic nerve sheath diameter on magnetic resonance imaging

Pediatric Radiology, 2019
The normal values of optic nerve diameter and optic nerve sheath diameter might be beneficial in defining an abnormality such as optic nerve hypoplasia, or enlarged subarachnoid space, reflecting the state of increased intracranial pressure.To study the normal optic nerve diameter and optic nerve sheath diameter on magnetic resonance imaging (MRI) in ...

Optic nerve sheath diameter changes at altitude

Acta Ophthalmologica, 2022
AbstractPurpose: This study aimed to assess variations in Optic Nerve Sheath Diameter (ONSD) as a correlate of Intracranial Pressure (ICP) during ascent to high‐altitude and to explore the relationship between ONSD and Acute Mountain Sickness (AMS). AMS is a high‐altitude illness characterized by headaches, lethargy, nausea and vomiting.

Optic Nerve Sheath Diameter

2020
Ocular sonography with optic nerve sheath diameter (ONSD) does not require specialized skills. This chapter describes the anatomical background supporting the use of ONSD as a surrogate marker of intracranial pressure (ICP). Normal views, technological issues, and methodological aspects are discussed, as well as possible pitfalls and safety concerns.

Effect of intracranial pressure on the diameter of the optic nerve sheath

Journal of Neurosurgery, 2008
Object The subarachnoid space around the optic nerve in the orbit can be visualized using T2-weighted MR imaging with the fat-saturation pulse sequence. The optic nerve sheath (ONS) diameter can be estimated by measuring the outer diameter of the subarachnoid space. Dilated ONS is associated with idiopathic intracranial hypertension and hydrocephalus,

Optic Nerve Sheath Diameter in Preterm Infants: Suggested Values

Neonatology, 2021
<b><i>Objective:</i></b> Timely detection of elevated intracranial pressure (ICP) in highrisk preterm infants may be critical to avoid permanent neurologic sequelae. Size of optic nerve sheath diameter (ONSD) is highly correlated with changes in ICP.

Evaluation of postictal optic nerve sheath diameter at epileptic patients

Epilepsy & Behavior, 2023
During a seizure, metabolic rate and, consequently, cerebral blood flow increase to provide the required maintenance energy. It is thought that this causes an increase in intracranial pressure, but there is no comprehensive research on this subject. In this study, we aimed to measure and follow optic nerve sheath diameter (ONSD) in patients who applied

Diagnostic value of the optic nerve sheath diameter in pseudotumor cerebri

Journal of Clinical Neuroscience, 2016
If persistent severe headache remains the only complaint of a patient, then the diagnosis of pseudotumor cerebri (PTC) can be delayed because in such cases practitioners are hesitant to immediately apply invasive intracranial pressure (ICP) measurement.
