Optic nerve sheath diameter changes at altitude
Acta Ophthalmologica, 2022AbstractPurpose: 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.

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, 2008Object 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,

Diagnostic value of the optic nerve sheath diameter in pseudotumor cerebri
Journal of Clinical Neuroscience, 2016If 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.
