NASA looks at visual impairment intracranial pressure risk in astronauts

March 2, 2015

CORONADO, Calif. — NASA is looking at causes of ocular changes in U.S. astronauts before, during and after 6-month space flights on board the International Space Station.

Ocular findings have developed in 22 of 31 astronauts so far, either during or after a 6-month flight, Christian Otto, MD, said at the annual meeting of the American Glaucoma Society. Those findings include hyperopic shift, choroidal folds, optic nerve sheath distention, optic nerve kinking, globe flattening, disc edema and cotton wool spots. In five of six subjects who underwent post-flight lumbar puncture, cerebrospinal fluid opening pressure was elevated by almost 21 cm H2O to 28.5 cm H2O.
