      Sensitivity of optical coherence tomography and visual evoked potential in demyelinating optic neuritis

      Aim The aim of this study is to analyze the structural and functional abnormalities of the optic nerve in multiple sclerosis (MS) patients utilizing optical coherence tomography (OCT) and visual evoked potential (VEP). We compare between eyes with and without a history of neuritis. Patients and methods A cross-sectional study which compared 60 eyes of MS patients with 20 eyes of the healthy control group. MS patients were classified into MS with optic neuritis (MS-ON, n =44) and MS without optic neuritis (MS-NON, n =16). Both VEP and OCT were done. Results Both groups showed thinning in the retinal nerve ...
