Assessing changes in the visual pathway in individuals with multiple sclerosis


  • Visual evoked potential (VEP), optical coherence tomography (OCT), and B-mode transorbital sonography (TOS) were valid techniques to monitor visual pathway damage in individuals with multiple sclerosis (MS).

Why this matters

    MS is a heterogeneous disease with a clinical course that varies between individuals. Studying the visual pathway has been of interest as changes there may reflect brain damage that contributes to patient disability. This study provides further evidence that visual pathway changes could act as a biomarker for brain axonal damage and may be successfully measured using inexpensive and noninvasive techniques.
