The increased intracranial pressure (ICP) can be described as an increase in pressure
around the brain and can lead to serious health problems. The assessment of ultrasound …

Neuro-ocular changes during long-duration space flight are known as spaceflight-
associated neuro-ocular syndrome (SANS). The ability to detect, monitor, and prevent SANS …

Background and purpose Ultrasonographic optic nerve sheath (ONS) diameter is a
noninvasive intracranial pressure (ICP) surrogate. ICP is monitored invasively in specialized …

Purpose Intracranial pressure increases in head‐down tilt (HDT) body posture. This study
evaluated the effect of HDT on the optic nerve sheath diameter (ONSD) in normal subjects …

Background Measurement of the optic nerve sheath diameter (ONSD) via ultrasonography
has been proposed as a non-invasive metric of intracranial pressure that may be employed …

Introduction Transorbital sonographic measurement of optic nerve sheath diameter (ONSD)
is an emerging non-invasive technique for the identification and monitoring of intracranial …

ABSTRACT BACKGROUND AND PURPOSE The optic nerve sheath diameter (ONSD) is a
promising surrogate marker for the detection of raised intracranial pressure (ICP). However …

Objective Characterization of the optic nerve through measurement of optic nerve diameter
(OND) and optic nerve sheath diameter (ONSD) using transorbital sonography (TOS) has …

Treatment with osmoactive agents such as mannitol or hypertonic saline (HTS) solutions is
widely used to manage or prevent the increase of intracranial pressure (ICP) in central …

Transorbital sonography is able to provide reliable information about (a) intra-cranial
pressure estimation through the optic nerve sheath diameter (ONSD) measurement, and (b) …
