Séminaire impromptu - Friedemann PAULRetinal Imaging in Neurology-current research and clinical applications

Abstract :

 Imaging of the retina with the help of high resolution spectral domain optical coherence tomography (OCT) has leveraged
both clinical and preclinical investigations of inflammatory and autoimmune processes that affect retinal tissue. In the past 10 years, our understanding of the pathophysiology of retinal damage and how this relates to global disease burden and clinical disability in neuroimmunological diseases such as optic neuritis, multiple sclerosis, neuromyelitis optica, Susac syndrome and others has substantially increased. Consequently, OCT is increasingly used to assess patients with autoimmune conditions of the central nervous system in clinical routine and is also implemented as outcome tool in clinical trials investigating the visual system. In preclinical research, OCT retinal imaging is used in animal models to deepen our understanding of the pathophysiologic mechanisms prevailing in these conditions.
The presentation will review both preclinical data and clinical applications of retinal imaging techniques and will discuss future research questions.
