Figure 1. Change in Pressure Measurements With −15° Head-Down Tilt (HDT) to Simulate Microgravity.

Figure 1.

Data are presented as estimated marginal mean (SD) for each postural allocation. EJVP indicates external jugular venous pressure; IJVP, internal jugular venous pressure; IOP, intraocular pressure; and TLPG, translaminar pressure gradient.

aP < .001 supine vs −15° HDT.
