Optic nerve evaluation in acute optic neuritis using transorbital sonography

Takeaway

  • Although transorbital sonography (TOS) is a highly accessible, safe, and user-friendly imaging method, no evidence for TOS-sensitive differences in the optic nerve diameter (OND) and optic nerve sheath diameter (ONSD) according to the presence of acute optic neuritis (ON) were observed.

Why this matters

    Imaging acute ON using TOS has been a promising method for diagnosis and follow-up. From this study, TOS does not appear to assist in the diagnosis of acute ON in individuals with a history of demyelinating diseases of the central nervous system (CNS); a large-scale study is suggested to confirm these findings.
