To the Editor Recently, Scott et al1 proposed a potentially simple treatment for spaceflight-associated neuro-ocular syndrome (SANS) with commercially available swimming goggles. The work and hypothesis of Scott et al1 regarding the countermeasures for SANS was interesting. In this letter, we point out potentially anticipated consequences for the lamina cribrosa (LC) of increasing the intraocular pressure (IOP) and intracranial pressure (ICP).
