PrefaceBack to top

The treatment of blindness caused by degenerative or dystrophic retinal diseases remains an unsolved medical but also social problem.
Although significant progress has been made, e.g. with the approval of the first gene therapy for RPE65 associated Leber’s Congenital Amaurosis (LCA) on one hand or with the fabrication and implantation of retinal implant systems in RP patients on the other hand, there is still a bumpy road ahead.

Several years ago the implantation of retina implant systems sounded as a success story. Totally blind subjects were able to perceive light, to locate and avoid obstacles, some were even able to slowly read large letters and to identify high contrast objects. However, this success was not well recognized in the ophthalmic community and in the patient community. The number of implantations did not meet the expectations and calculations of the companies. As a result, e.g. Retina Implant AG stopped fabricating the Alpha AMS device and Second Sight also stopped their Argus II activities. Clinical results in a larger scale are now expected from trials with the subretinal photovoltaic device of PIXIUM and also from the cortical stimulation device ORION. Other activites are expected from the Australian and from the Japanese consortium and possibly also from other groups.

However, we learned a lot from the experiences with the early implants. Many research projects are still running to better understand the mechanisms of retinal degeneration, how to interfere with these mechanisms, what components of retinal or cortical implants can be improved or optimized to achieve a better outcome. New projects are planned to solve more general bottlenecks of retinal stimulation using implants.

The Artificial Vision 2019 Conference in Aachen, Germany serves as an interdisciplinary forum bringing together researchers of all disciplines involved in the design, planning, fabricating and testing of visual prostheses as well as scientists from the neurobiological world giving insights in the process of visual system degeneration. We also welcome the participation of patients in this conference to better understand their needs and expectations.

This conference is a fully open, non-invitational meeting. For young researchers we will have a number of travel grants available. The conference is supported by the German Research Association (Deutsche Forschungsgemeinschaft, DFG).

We are welcoming talks and presentations related to any aspect of Artificial Vision. Please send in an abstract via the online abstract submission system ( not later than by September, 29th.

Together with my colleagues Wilfried Mokwa (RWTH), Frank Müller and Andreas Offenhäusser (RC Julich) I cordially invite you to come to Aachen.

Congress OutlineBack to top

The goal of the International Symposium on Visual Prosthetics – Artificial Vision 2019 – is to provide a platform for researchers and clinicians to meet, to present, and to discuss the 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

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.

Travel Grants for young researchers

We especially encourage young researchers to come to the Aachen Meeting and to present your own work and to discuss all aspects of visual prosthetics with colleagues from many different disciplines and countries. To make things easier we will provide travel grants of up to 2,000 EUR for young researchers. Although it is difficult or in other words impossible to define a threshold for being young, a poorly artificial definition and limit has to be set. We feel that usually researchers younger than 40 years of age need more financial support than the older ones. We may be wrong but somehow we need a definition.

To apply for a travel grant please send a CV and a motivation letter to:

Aachen and the EUREGIO area

The city of Aachen is the most western city in Germany close to the borders of The Netherlands and Belgium. Aachen has approx. 250,000 inhabitants and the University and the University Hospital are the largest employer here in Aachen. Aachen has a long history and you can still see significant witnesses of a time long ago, such as the cathedral with its beautiful and mystic octagon and the astonishing gothic city hall. But Aachen with its important historic phase of Charlemagne today is a young and vivid town with its university and the many students from various countries in the world. RWTH Aachen University is one of the leading technical universities in Europe with a strong focus on mechanical and electrical engineering but also on information technology and natural sciences. Aachen forms a cultural, industrial and also scientific cross border triangle together with Liege in Belgium and Maastricht in The Netherlands forming the EUREGIO area. Many cooperations exist between the institutions within this area.

The Artificial Vision Meeting is set to the beginning of December. Although the weather might not be perfect – in fact it could be cold and maybe rainy – it is worth to visit the cosy Christmas Market in the city. You should try “Printen”, a local biscuit speciality with a high “addiction” potential.

Aachen is also not far away from Cologne with its huge cathedral and its several concert halls and the province capital Düsseldorf with its important art and fashion scene. You can also reach the European capitals Paris and Brussels by high speed train within a few hours.

There are also many more reasons to come and visit Aachen and we are looking forward to see you.
