Value of Optic Nerve Sheath Diameter in Differentiating Ischemic From Hemorrhagic Stroke
Sponsor: Ankara City Hospital Bilkent
Summary
We aimed to examine bedside ONSD values measured by ocular ultrasonography in patients presenting to the ED with stroke, and to determine a diagnostic cut-off value for differentiating ischemic from hemorrhagic stroke.
