mac.com Objective: To investigate the association of optic nerve sheath diameter (ONSD), as a correlate of intracranial pressure (ICP), with acute mountain sickness (AMS). Design: Longitudinal cohort ...

and Nisonic combines the optic nerve sheath diameter (ONSD) with additional information gathered from the nerve sheath to estimate the pressure. "Many neurosurgeons are already using ONSD as a ...

Relationship Between Optic Nerve Sheath Diameter, Deformability Index, and Intracranial Pressure, Operative Neurosurgery (2018). DOI: 10.1093/ons/opy231 Chiara Robba et al, Optic nerve sheath ...

optic nerve ultrasonography (optic nerve sheath diameter sonography) is emerging as a rapid, noninvasive alternative in these cases. However, use of this method remains predominantly limited to ...

A statistically significant reduction in echographic optic nerve sheath diameter was observed in all patients at 3 months postop (P < .001), with further reductions at 6 months (P = .023).

Other methods are invasive, involve radiation, and are not cost-effective," Hedna said in the article, adding, "We feel the optic nerve sheath diameter would just help the clinician make the ...

The optic nerve sheath was approximately twice the diameter of a normal optic nerve sheath and had an irregular and highly vascular appearance. A small portion of the optic nerve sheath was sampled.

The researchers are still studying whether differences in optic nerve sheath diameter from day one to day two were related to patients' risk of death or disability. The team plans to study whether ...
