Visual Outcomes after Anterior Temporal Lobectomy and transsylvian Selective Amygdalohippocampectomy - A Quantitative Comparison of Clinical and Diffusion Data.

In the context of controversial visual outcomes following epilepsy surgery, this study provides clinical as well as neuroimaging evidence for a higher risk and greater severity of postoperative VFDs after ATL compared to tsSAHE. Volumetric OpR-tractography-damage is a feasible parameter to reliably predict this morbidity in both treatment groups and may ultimately support personalized planning of surgical candidates. Advanced diffusion-analysis tools such as FBA offer a structural explanation of surgically induced visual pathway damage, allowing to non-invasively quantify and visualize micro- and macrostructural tract affection.
