Astronauts have returned from space with visual impairment and intracranial pressure.  One theory is that the intracranial pressure on the optic nerve may be the cause of the change in vision. Digital Astronaut is working to understand the dynamics of this condition so that we can reduce the effects for future crewmembers.

Ocular changes

We do not know the etiological mechanisms and contributing risk factors for ocular structural and functional changes seen in-flight and post-flight.

Evidence from medical records, spaceflight operations and research findings provides the basis for identifying the most significant human risks in space exploration, including physiological and performance effects from hazards such as altered gravity, radiation, hostile/closed environments, isolation and distance. Each risk is assigned to an HRP Element (divisions of human research) to identify knowledge gaps, or the critical questions that must be answered, in order to mitigate the risk. These gaps become the focus of research conducted to reduce the likelihood and consequence of risks becoming a reality.
