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 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.

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.

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 ...
