Optic nerve sheath diameter measurement: a means of detecting increased intracranial pressure in pseudotumor cerebri patients [PDF]

Folia Morphologica, 2022
BACKGROUND: Pseudotumor cerebri (PTC) occurs when the pressure inside the skull increases for no obvious reason. The aim of this study was to investigate three different methods: the optic nerve sheath diameter (ONSD) method, ONSD/eyeball transverse ...

The Prognostic Value of Optic Nerve Sheath Diameter/Eyeball Transverse Diameter Ratio in the Neurological Outcomes of Out-of-Hospital Cardiac Arrest Patients

Medicina, 2022
Background and objectives: The optic nerve sheath diameter (ONSD) is indicative of elevated intracranial pressure. However, the usefulness of the ONSD for predicting neurologic outcomes in cardiac arrest survivals has been debatable. Reportedly, the ONSD/

Bedside ultrasonographic assessment of optic nerve sheath diameter as a means of detecting raised intracranial pressure in neuro-trauma patients: A cross-sectional study

Annals of Indian Academy of Neurology, 2021
Background: Optic nerve sheath diameter (ONSD) measurement is emerging as a noninvasive method to estimate raised ICP. It is helpful in situations where imaging of brain or direct ICP monitoring is not available or feasible. Use of ONSD is still limited,
