• Research summary

  Anterior temporal lobe resection for temporal lobe epilepsy carries a risk of injury to the optic radiations, that can result in a visual field defect in the patient. The optic radiation can be visualised by a technique known as tractography. Previous work has demonstrated that intra-operative visualisation of the optic radiation tractography in the interventional MRI suite reduces the risk of acquiring a new visual field deficit. We seek to repeat this study using the Medtronic Stealth Neuronavigation system with microscope integration. The surgeon will have the optic radiation outline overlaid on the microscopic field. We will follow up this cohort of patients with postoperative formal assessment of visual fields.
