  • CONCLUSIONS: This study further delineates the profile of RON. Visual loss is often acute, profound, and monocular but may decline slowly after acute onset and later affect both optic nerves. High-resolution MRI of the optic nerves usually will display enhancement of a discrete segment of the intracranial prechiasmatic optic nerve, often with accompanying expansion and T2 hyperintensity. In some cases, these imaging features may precede vision loss. They may be subtle or appear after vision loss. Enhancement lingers for a wide interval, ranging in this study from 2 to at least 17 months. Recognition of these imaging characteristics assists in confirmation of the diagnosis of RON.
