Space Station Live: Ocular Health for Astronauts – 06.05.13
› Watch video

Aboard the International Space Station, Flight Engineers Karen Nyberg and Luca Parmitano recently began the first runs of an important new study looking into the vision changes experienced by astronauts during long-duration missions.

Dr. Christian Otto, principal investigator for the Prospective Observational Study of Ocular Health in ISS Crews experiment (Ocular Health), joined NASA Public Affairs Officer Nicole Cloutier LeMasters in station’s Flight Control Room at the Mission Control Center in Houston to discuss this program to document astronaut eye health during spaceflight.

Astronauts in space experience fluid shifts to the head caused by microgravity, and its hypothesized that all crew members experience increased intercranial pressure to some degree. Researchers have linked this increased pressure to vision changes in long-duration astronauts.

Over the next few years, the Ocular Health study will document systematically any changes in astronauts’ eye health over their six-month increments. Results from these studies also will be beneficial to patients here on Earth who are suffering from diseases such as glaucoma.
