About The Study: The findings of this study suggest crewmembers who did not develop optic disc edema (ODE) on flight day 30 were unlikely to develop clinically concerning ODE on flight day 150. The data suggest that optical coherence tomography imaging during spaceflight missions provides an opportunity to predict the magnitude of ODE that may develop during a longer-lasting mission.
