Ryan's Retina

Dr. Peter Wiedemann is Professor of Ophthalmology at Leipzig University. He is a vitreoretinal specialist whose expertise includes complex vitreoretinal surgery and macular disorders. Dr. Wiedemann earned his medical degree at Erlangen University, Germany. He started ophthalmic research at the Doheny Eye Institute, Los Angeles, with Dr. Stephen Ryan and completed residency and fellowship in ophthalmology at Cologne University with Prof. Klaus Heimann. In his research Dr. Wiedemann studies retinal and macular disorders and Müller cells pathophysiology. He has authored over 500 peer reviewed publications in ophthalmology and is co-editor of the textbook Ryan´s Retina. He is a member of the German National Academy of Sciences Leopoldina, the German Ophthalmological Society, the American Academy of Ophthalmology and the Club Jules Gonin.
