Up to now the recording of electroretinograms (ERGs) and visual evoked potentials (VEPs) is running with a connection to mains power. The instrument “Ephios Eph-01” is able to record ERGs and flash-VEPs without any power supply, which makes it portable at any time. In this study, the instrument was tested in terms of reproducibility of the results based on 20 subjects (ERG) and 10 subjects (VEP). Subsequently, a comparison between the results of “Ephios Eph-01” and the “Toennies Multiliner Vision 1.5”, one of the established instruments in the clinical routine, was drawn. Furthermore, the acceptance of the subjects and the feasibility was examined. As a result, it was shown that the “Ephios Eph-01” is generating reproducible results. The comparison of the instruments showed a significant correlation of the latency of the VEPs. The analysis of the ERGs didn´t generate a consistent result.
