Ultrasound assessment of optic nerve sheath diameter in healthy volunteers

Journal of Critical Care, 2016
Ultrasound assessment of optic nerve sheath diameter (ONSD) has been suggested as a non-invasive measure of intracranial pressure. Numerous small studies suggest its validity; however, discrepancy exists around normal values for ONSD. In this study we sought to define a normal value range for ONSD in a population of healthy adult volunteers.ONSD was ...

Optic Nerve Sheath Diameter for Preterm Infants: A Pilot Study

Neonatology, 2019
<b><i>Objective:</i></b> In preterm infants, early diagnosis and management of a raised intracranial pressure (ICP) may be important to improve neurodevelopmental outcomes. While invasive ICP monitoring is not recommended, ultrasonography of the optic nerve sheath diameter (ONSD) could provide a ...

Optic nerve sheath diameter in normal-tension glaucoma patients

British Journal of Ophthalmology, 2011
Background To report on the optic nerve sheath diameter (ONSD) in patients with normal-tension glaucoma (NTG) compared with controls without known optic nerve (ON) or intracranial disease. Methods In 18 patients with NTG (mean age 64.9±8.9 years; 7 women and 11 men), CT of the orbit was performed.

Optic nerve sheath diameter does not change with patient position

The American Journal of Emergency Medicine, 2005
Optic nerve sheath diameter (ONSD) has been proposed as a marker for increased intracranial pressure. Trendelenburg's position is often used in hypotensive patients and reverse Trendelenburg's position (30 degrees head up) is often used in head injury patients.
