DOI: 10.1001/jamaophthalmol.2022.1946
Abstract: Importance Countermeasures that reverse the headward fluid shift experienced in weightlessness have the potential to mitigate spaceflight-associated neuro-ocular syndrome. This study investigated whether use of the countermeasure lower-body negative pressure during spaceflight was associated with… read more here.
