Hintergrund: Degenerative Netzhauterkrankungen, zum Beispiel Retinitis pigmentosa, führen immer noch zu einem unaufhaltsamen Sehverlust. Eine moderne Methode der Behandlung ist die Implantation von Netzhautstimulatoren. Unsere Gruppe hat sich das Ziel gesetzt, einen besonders großflächigen[zum vollständigen Text gelangen Sie über die oben angegebene URL], 31. Jahrestagung der Retinologischen Gesellschaft

Objective: Degenerative retinal diseases, i.e. Retinitis pigmentosa, lead to a severe decline of visual function. Over the last decades crucial progress in artificial vision conquering imminent vision loss has been achieved. We developed a large array epiretinal stimulator and tested its biocompatibility,[for full text, please go to the a.m. URL], Artificial Vision 2017

Objective: The use of multielectrode arrays (MEAs) allows the physiological characterisation of the retinal neural network. Additionally, MEAs have been described for the electroporation-based transfer of exogenously added molecules. Cells are exposed to an electrical field which results in a reversible[for full text, please go to the a.m. URL], Artificial Vision 2017

Objective: Assess the recording capabilities of custom made penetrating microelectrode arrays (MEAs) for in vitro experiments. Materials and Methods: The spontaneous spiking activity of retinal ganglion cells (RGCs) and responses to optic stimulation as well as to treatment with high potassium concentration[for full text, please go to the a.m. URL], Artificial Vision 2017

Background: The VLARS (very large array retina stimulator) was designed for the purpose of epiretinal stimulation. Due to its unique composition of materials and good surgical feasibility this study aims to determine the feasibility of suprachoroidal-transretinal stimulation of the VLARS device as a[for full text, please go to the a.m. URL], Artificial Vision 2015

Objective: The objective of this work is to develop a flexible microelectrode array (MEA) for an epiretinal prosthesis with high acuity and a large field of view. To ensure a good contact with the retinal tissue and reduce the pressure exerted by the edge area of the structure on the retina these arrays[for full text, please go to the a.m. URL], Artificial Vision 2015

Background: To analyze the biocompatibility of Ruthenium nano-lawn structures in order to optimize the properties of microelectrodes, embedded in prostheses to induce electrical stimulation of surviving retinal cells, in terms of charge transfer capacity and signal-to-noise ratio. Methods: The nano-lawn[for full text, please go to the a.m. URL], Artificial Vision 2015

Objective: The objective was to develop a flexible multi-electrode array with an integrated silicon chip for stimulation of neurons. Materials and Methods: Micro-electrodes and micro-electrode arrays (MEAs) are widely used in medical applications and biological research.
