Optic nerve sheath diameter in raised icp
WebApr 10, 2024 · Recently, the optic nerve sheath diameter (ONSD) has become widely used as a surrogate parameter for the noninvasive estimation of ICP [ 7 ]. Anatomically, some of the space surrounding the optic nerve is a direct extension of the subarachnoid space containing cerebrospinal fluid (CSF). WebBackground: Optic nerve sheath tortuosity is a previously reported, but incompletely characterized, finding in idiopathic intracranial hypertension (IIH). We hypothesized that optic nerve angle (ONA), as a quantitative measure of tortuosity, would change dynamically with cerebrospinal fluid (CSF) pressure status of patients with IIH immediately ...
