Purpose Although invasive intracranial devices (IIDs) are the gold standard for intracranial
pressure (ICP) measurement, ultrasonography of the optic nerve sheath diameter (ONSD) …

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

Background The invasive nature of the current methods for monitoring of intracranial
pressure (ICP) has prevented their use in many clinical situations. Several attempts have …

Monitoring of intracranial pressure (ICP) is invaluable in the management of neurosurgical
and neurological critically ill patients. Invasive measurement of ventricular or parenchymal …

Importance The crtierion standard method for monitoring intracranial pressure (ICP) can
result in complications and pain. Hence, noninvasive, repeatable methods would be …

Optic nerve sheath diameter (ONSD) ultrasound is becoming increasingly more popular for
estimating raised intracranial pressure (ICP). We performed a systematic review and …

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 …

Objectives The correlation of optic nerve sheath diameter (ONSD) as seen on
ultrasonography (US) and directly measured intracranial pressure (ICP) has been well …

Introduction Measurement of optic nerve sheath diameter (ONSD) by ultrasound is
increasingly used as a marker to detect raised intracranial pressure (ICP). ONSD varies with …

Measuring intracranial pressure (ICP) is necessary for the treatment of severe head injury
but measurement systems are highly invasive and introduce risk of infection and …
