Vision Impairment and Intracranial Pressure (VIIP) – 11.22.16

Science Objectives for Everyone
The Vision Impairment and Intracranial Pressure (VIIP) project examined the effect of long-term exposure to microgravity on the structure of the eye along with change in distance and near vision of crew members before and after they returned to Earth.

Science Results for Everyone
I can see (less) clearly now. Many astronauts experience poorer vision after flight, some even for years after. A number of studies have looked for causes and distinct physical changes in the eye itself have been found. MRI scans suggest that pressure changes in the brain and spinal fluid caused by weightlessness may be partly to blame. Many astronauts do not show these effects, though, and more advanced imaging techniques may be needed to understand the role of changing brain pressure in microgravity. This in turn will help researchers assess vision problems and develop ways to prevent them.
