Prediction of Optic Disc Edema Progression in Spaceflight

Neuro-ocular changes have been described in astronauts after long-duration spaceflight, including optic disc edema (ODE), choroidal folds, globe flattening, and a refractive hyperopic shift. Collectively, these findings have been termed spaceflight-associated neuro-ocular syndrome (SANS). Carter et al performed interesting and elegant work exploring the possibility of predicting the magnitude of ODE in astronauts after long-duration space missions.
