Handheld ultrasound imaging provides real-time, noninvasive imaging in variable and even nonclinical environments. The development of increasingly portable, handheld ultrasound devices, and the iteration of increasingly user-friendly interfaces, has made sonography an accessible technique for even early practitioners. 22 In spaceflight, ultrasound is commonly used given relatively lightweight imaging options, broad applications for multiple uses, and relative ease of use. 11 , 14 , 16 Currently, ultrasound is the only imaging capability available on the

, noting a 5-mmHg average increase in IOP ( N = unknown) using a hand-held applanation tonomoter. 4 In another parabolic flight study, IOP increased by 7 mmHg (58%, N = 11) within 20 s of weightlessness, measured with a Tono-Pen. 11 Preliminary studies in normal astronauts showed elevations in IOP in the first few hours into microgravity with normalization to baseline IOP values within 4 d in flight. In the German D1 Spacelab mission, IOP increased by 20–25% ( N = 1) after 44 min of microgravity exposure followed by a decrease to baseline. 3 Similarly
