Intraocular pressure (IOP) measurements. (A) Mean pre-and post-flight IOP for flight (FLT) and ground control (GC) mice for left eyes (n = 20). (B) Mean pre-and post-flight IOP for FLT and GC mice for right eyes (n = 20). The animals exhibited no signs of irritation or discomfort during the procedure. Six readings were made to obtain an average count as a single IOP readout. Three IOP measurements were obtained for each eye. Values are means ± SEM. *Significantly lower than that of preflight (p < 0.05).
