The contribution of magnetic resonance imaging in the differential diagnosis of optic nerve damage

In this paper we review the findings of magnetic resonance imaging (MRI) in optic neuritis and visual dysfunction due to other optic neuropathies. Wit h advances in MRI technology, it has become possible to visualise optic ner ve pathology. STIR and RARE sequences, contrast-enhanced sequences, and pha sed array surface coils are technical developments that provide fine anatom ical detail and that are sensitive to pathological changes. MRI can offer i nformation in the differential diagnosis of optic neuropathies, the monitor ing of their treatment, and in some instances should provide new insights i nto the underlying pathophysiological mechanisms.
