Dr. Lukas Streese is part of a research group at Düsseldorf University Hospital that aims to investigate the effects of gravitational changes on microcirculation. Astronauts who spend long periods in space face the problem of developing visual impairments. The cause of the so-called "spaceflight-associated neuro-ocular syndrome" (SANS) is not yet known. The "Retinal circulation during gravitation changes in a human centrifuge" (RIDGE) project, led by Prof. Christian Jung from the Department of Cardiology at the University Hospital in Düsseldorf, is trying to get to the bottom of the causes of microvascular changes in the eye. This project also aims to test possible forms of therapy that can reduce the negative effects of space travel on vision. Dr. Lukas Streese is part of the research team that was able to raise €600,000 in funding for this project. Mr. Streese will contribute his expertise in retinal vascular diagnostics to this project. Mr. Streese has already carried out the first trial measurements with the research team (see images). The aim is to measure the retinal microcirculation at different g-forces during the rotation of the centrifuge. The aim is to compare different body positions. The RIDGE project is a great example of how the Tandem Niederrhein project enables interdisciplinary collaboration.
