To the Editor Marshall-Goebel et al¹ examined an important safety concern for long-duration spaceflight—whether or not there is an association between postflight structural brain changes and increased total retinal thickness, considered to be a diagnostic criteria for spaceflight-associated neuro-ocular syndrome (SANS). The authors conclude “cerebrospinal fluid redistribution…does not play a substantial role in the development of optic disc edema.”¹

颅内隔室在航天相关神经眼综合征发展中的重要性

致编辑Marshall-Goebel 等人¹研究了长期太空飞行的一个重要安全问题——飞行后大脑结构变化与视网膜总厚度增加之间是否存在关联，这被认为是太空飞行相关神经系统的诊断标准。眼综合征（SANS）。作者得出结论：“脑脊液再分布……在视盘水肿的发展中没有发挥重要作用。” ¹
