Eye nerve size on CT may predict death risk after brain aneurysm rupture

This completed study looked at 114 adults with a type of brain bleed called subarachnoid hemorrhage from a ruptured aneurysm. Researchers measured the optic nerve sheath on early CT scans to see if the size could predict whether a patient would survive for 6 months. The goal was to find a quick, non-invasive way to assess prognosis right after the bleed.
