Optical Coherence Tomography Analysis of the Optic Nerve Head and Surrounding Structures in Long-Duration International Space Station Astronauts

Abstract

After long-duration microgravity exposure, there are disc edema-like changes in the morphology of the ONH and surrounding tissue. The methods developed to analyze the ONH and surrounding tissue can be useful for assessing longitudinal changes and countermeasures in astronauts, as well as potentially for terrestrial disc edema causes.
