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 …

Background: Optic nerve ultrasonography (optic nerve sheath diameter sonography) has
been proposed as a noninvasive, quick method for diagnosing increased intracranial …

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 …

Point of care ultrasound (POCUS) allows for rapid, real-time evaluation of cardiovascular
and respiratory pathology. The advent of portable, handheld devices and increased …

Background While venous congestion in the peripheral vasculature has been described and
accepted, intracranial venous congestion remains poorly understood. The characteristics …

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

The objectives of the study were to investigate the value of optical coherence tomography in
detecting papilledema in patients with idiopathic intracranial hypertension (IIH), a disease …

Purpose Monitoring of raised intracranial pressure (ICP) in patients with idiopathic
intracranial hypertension (IIH) is required to prevent secondary optic nerve damage …

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 …

Background Ultrasound measurements of optic nerve sheath diameter (ONSD) and optic
disc height (ODH) measured outside pregnancy correlate with intracranial hypertension …
