Abstract

During long-duration spaceflights, some astronauts exhibit ocular structural and functional changes called SANS. Monitoring for SANS is challenging due to time and payload constraints that limit which tests can be performed and at what frequency. A virtual reality (VR)-based system that monitors relevant aspects of ocular properties through multimodal visual function testing can enhance the diagnosis of SANS. Combining visual acuity, color, and contrast sensitivity, visual field and distortion measurement in a short and immersive VR test allows more data to be collected in a shorter period and may reduce the number of devices that need to be sent onboard space missions.
