Artificial Vision 2015 REGISTRATION
27th-28th November 2015
Aachen, Germany

PREFACEBack to top

Worldwide about 150 blind patients received electronic Retina Implant Systems. Currently two products are approved for the use in humans, but more prototypes are in development and a few have been implanted in patients. Electronic visual implants are complex and highly integrated microsystems and many innovations representing cutting edge technologies are used for their fabrication process. However, as we learn from working with patients being implanted with such systems many open questions remain and need to be addressed to improve the outcome of such systems. The fourth International Symposium on Artificial Vision is planned to address these open questions with enough time in a very relaxed and friendly atmosphere. This meeting will provide an interdisciplinary platform for specialists in Ophthalmology, Visual and Neuroscience, Electrical Engineering, Material Science, Computer Science, and Rehabilitation to exchange their thoughts and to learn from each other. Topics among others are mechanisms of degeneration in the visual system and their influence on cellular networks, principles of cell stimulation, electrode – cell interface, design and hardware for electronic visual implants, microsystems fabrication, surgery for electronic implants, biocompatibility, preclinical functional tests, recruitment of patients, patient reported outcomes and measurement of Artificial Vision.

The meeting will take place in Aachen, Germany, the city of RWTH Aachen University, which is one of the leading technical universities in Europe, a place where Natural and Life Sciences, Medicine, and Engineering and Technology are strongly connected. Aachen can be reached easily via the airports of Düsseldorf, Cologne, Frankfurt, Amsterdam or Bruxelles, or by train connections. My colleagues Wilfried Mokwa from RWTH University Aachen, Frank Müller and Andreas Offenhäusser from the Research Center Jülich and I, we cordially invite you to come to Aachen and join us in discussing present aspects and thinking about the future of visual prosthetics.

The thresholds for retinal stimulation in blind RP subjects.
Franz Reuter, Julia Sachtweh, Reinhard Meier
Department of Ophthalmology, Island City, Elsewhere

Objective. To describe the stimulation thresholds for subretinal stimulation using platinum red electrodes embedded into new insulation materials.
Materials and Methods. In six blind RP patients a new subretinal device was implantated and cortical potentials were recorded upon electrical retinal stimulation. Cortical potentials were determined using a new response isolation algorithm developed by Meier et al. The cortical responses were correlated with stimulus parameters.
Results. In all six patients the implantation was done successfully. All patients had visual percepts. In all patients cortical potentials can be recorded and the the stimulus duration necessary to obtain a response was 67 ms cathodic first with an mean amplitude of 435 μV.
Discussion. The stimulation at threshold was well within the non-toxic range for tissue stimulation and no patient had any adverse events.
Acknowledgment. This work was supported by ABC grant 874987.


The goal of the International Symposium on Visual Prosthetics – Artificial Vision 2015 is to provide a platform for researchers and clinicians to meet, to present, and to discuss latest advances and achievements in the field of providing vision with electronic implants to the blind. The symposium will cover all aspects of Artificial Vision such as
