The EPI-RET device is the result of the collaborative work of the EPI-RET research consortium coordinated by Rolf Eckmiller (Bonn), Wilfried Mokwa (Aachen), and Peter Walter (Aachen). The main and outstanding contributions to the system, its development, and construction have been given by persons in several centers in Germany, including: Klaus Heimann (deceased 1999), Peter Szurman, Pia Königsfeld, Michael Vobig, Svetlana Held, Reza Shojai, Elham Farvili, Guilia Marzella, and Peter Ruokonen (Department of Ophthalmology, University Hospital Cologne); Norbert Bornfeld, Thomas Laube, Achim Wessing, and Rolf Effert (Department of Ophthalmology, University Hospital Essen); Heinrich Gerding, Constantin Uhlig, and Suphi Taneri (Department of Ophthalmology, University Hospital Münster); Bedrich Hosticka, Hoc Khiem Trieu, Ingo Krisch, Lutz Ewe, Markus Schwarz, and Steffan Kolnsberg (Fraunhofer Institute of Microelectronic Circuits and Systems [IMS], Duisburg); Wilfried Mokwa, Uwe Schnakenberg, Gert Spanier, and Kaspar Hungar (Institute of Materials in Electrical Engineering, RWTH Aachen University); Jörg Uwe Meyer, Thomas Stieglitz, and Werner Haberer (Fraunhofer Institute for Biomedical Engineering [IBMT], St. Ingbert); Horst Richter, Christian Mittermayer, Hans-Christian Lüdtke Handjery, Bernd Sellhaus, and Stephanie Müller-Kämpf (Institute of Pathology University Hospital, RWTH Aachen); Reinhard Eckhorn, Thomas Schanze, Lutz Hesse, and Holger Wilms (Institute for Neurophysics, University of Marburg); Rolf Eckmiller, Ralf Hornig, Natalia Peixoto, Sven Meyburg, Oliver Baruth, and Dirk Neumann (Institute of Neuro Informatics, University of Bonn); Dieter Jäger, Rüdiger Buss, and Frank Prämassing (Institute of Optoelectronics, University of Duisburg), and many others.
