Diffusion tensor imaging of the optic disc in idiopathic intracranial hypertension?

I read with great interest the article by Razek et al. in which they illustrate the results of their study investigating the utility of diffusion tensor imaging (DTI) of the optic disc in differentiating between patients with idiopathic intracranial hypertension (IIH) and control individuals . The authors reported devastating results supporting the possible value of DTI parameters of the optic disc in the clinical evaluation of IIH including significant differences between patients (IIH) and controls; patients with early papilledema and advanced papilledema; patients with early visual field defects; and patients with advanced visual field defects for both parameters of DTI (FA and MD). In their study conclusion, the authors emphasized that DTI parameters of the optic disc are non-invasive reliable imaging tools that may help in the diagnosis of IIH, and they remarked that it was well correlated with the degree of papilledema and visual field defects. First, I...
