Background Estimation of intracranial pressure (ICP) may be helpful in the management of
neurological critically ill patients. It has been shown that ultrasonography of the optic nerve …

Abstract Background and Purpose Reported cutoff values of the optic nerve sheath diameter
(ONSD) for the diagnosis of elevated intracranial pressure (ICP) are inconsistent. This …

The optic nerve sheath diameter (ONSD) is considered as an indirect marker for intracranial
pressure (ICP). However, the optimal cut-off value for an abnormal ONSD indicating …

ABSTRACT BACKGROUND AND PURPOSE To date, normal values for optic nerve
diameter (OND) and optic nerve sheath diameter (ONSD) for transorbital sonography (TOS) …

Measuring and monitoring of intracranial pressure is considered standard of care in patients
with suspected intracranial hypertension. Sonographic assessment of the optic nerve sheath …

Background Transorbital sonography (TOS) has been proven to be able to non-invasively
detect elevated intracranial pressure. In this condition TOS shows an increase in optic nerve …

In patients with idiopathic intracranial hypertension (IIH), transorbital sonography (TOS) may
reveal an enlargement of the optic nerve sheath diameter (ONSD) and the presence of optic …

The measurement of optic nerve sheath diameter (ONSD) has been reported as a non-
invasive marker for intracranial pressure (ICP). Nevertheless, it is uncertain whether …

Background The results of studies on changes in intracranial pressure in patients
undergoing laparoscopic surgery are inconsistent. Meanwhile, previous neurosurgery …

Background Our objective was to assess optic nerve sheath diameter (a marker of elevated
intracranial pressure) and optic disc elevation (a marker of papilledema) in pseudotumor …
