Diffusion-Weighted Imaging of Traumatic Optic Neuropathy: Diagnosis and Predicting the Prognosis
Abstract
Traumatic optic neuropathy is an axonal injury of the optic nerve fibers and occurs from a number of mechanisms both in blunt and penetrating trauma. Out of all the types of ocular injuries, traumatic optic neuropathy has one of the worst visual outcomes. For this study, we intended to use high-resolution diffusion-weighted magnetic resonance imaging (DW-MRI) to obtain sufficiently high resolution and detailed imaging of the optic nerve at two time points. This powerful tool has the potential to help predict the outcomes including the degree of vision recovery. We screened patients admitted to the University of Maryland Shock Trauma Center and attempted to recruit them for an initial DW-MRI during their hospital stay, with the intention of doing a 6-month follow-up. Due to uncontrollable circumstances, only one patient underwent MRI of the optic nerves according to the specified protocol. No significant findings or results were obtained from this study. If a follow-up appointment were not required for this study, more patients would have been receptive.
