A preliminary application of the diffusion tensor imaging in estimating the functional and structural recovery of the visual pathway in Dysthyroid Optic Neuropathy patients after intravenous methylprednisolone pulse therapy.

The management of DON (dysfunction optic neuropathy) is complex, an effective method to reflect the response of treatment is indispensable. We use the MRI-DTI combine d with DtiStudio software to assess the visual pathway changes in DON patients pre and post intravenous methylprednisolone pulse therapy. The results did demonstrate the improvement of visual pathway. The DTI can be regarded as a reliable tool to assess and follow up DON patients during therapy.
