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 Spontaneous intracranial hypotension (SIH) is a condition of low cerebrospinal
fluid volume and pressure caused by a leak of cerebrospinal fluid through a dural defect …

Background Quantification of the optic nerve sheath diameter (ONSD) by transbulbar
sonography is a promising non-invasive technique for the detection of altered intracranial …

OBJECTIVE: Low cerebrospinal fluid pressure (CSF-P) may be involved in the pathogenesis
of glaucoma. We measured the optic nerve subarachnoid space width (ONSASW) as a …

Introduction The orbital subarachnoid space surrounding the optic nerve is continuous with
the circulation system for cerebrospinal fluid (CSF) and can be visualized by using magnetic …

BACKGROUND AND PURPOSE: IIH is a disorder associated with increased intracranial
pressure with no clinical, laboratory, or radiologic evidence of an intracranial space …

Spontaneous intracranial hypotension (SIH) is a condition that results from leakage of
cerebrospinal fluid (CSF) from the spine, and which typically presents with debilitating …

Background: Invasive intracranial pressure (ICP) can result in complications, pain, or even
aggravate intracranial hypotension (IH) or headache in patients with IH. Objective: To …

Intracranial hypotension is not an uncommon diagnosis after lumbar puncture or
neurosurgery. However, spontaneous intracranial hypotension (SIH) is a poorly understood …

OBJECTIVE. Intracranial hypotension is an uncommon cause of headaches that is often
misdiagnosed. The classic MRI features of intracranial hypotension can be variable and …
