The imo has an eye tracking system that records eye position during tests and assists the device with stimulating corrected points corresponding to eye movement.

They were then passively exposed to simulated 4000 m above sea level for 3 hours and underwent acute mountain sickness (AMS) symptoms evaluation and IOP measurement after 2 hours exposure to HH (T2). Repeat SS AS-OCT measurements and IOP assessments were taken within 15 minutes after leaving the hypobaric chamber (T3). Anterior segment parameters including anterior chamber depth (ACD), lens vault (LV), angle opening distance (AOD500), trabecular-iris space area (TISA500), angle recess area (ARA500) at 500 μm from the scleral spur, iris curvature (IC), iris volume (IV), pupil diameter (PD), and central corneal thickness (CCT) were obtained through SS AS-OCT. These repeated measurements were compared using linear mixed model analysis.</p><p><strong>Results: </strong>In comparison to the sea level, both IOP (16.4±3.4 vs. 14.9±2.4 mm Hg, P =0.029) and PD (5.36±0.77 vs. 4.78±0.89 mm, P =0.001) significantly decreased after exposure to HH. Significant post-HH changes [mean difference (95% CI)] were observed in AOD500 [0.129 (0.006, 0.252), P =0.04], TISA500 [0.059 (0.008, 0.11), P =0.025], ARA500 [0.074 (0.008, 0.141), P =0.029], IV [1.623 (0.092, 3.154), P =0.038], and IC [-0.073 (-0.146, 0.001), P =0.047], whereas CCT, ACD, and LV remained stable. After adjusting for age, post-HH variations in AOD500 (Beta=0.553, 95% CI: 0.001, 1.105, P =0.048) and TISA500 (Beta=0.256, 95% CI: 0.02, 0.492, P =0.034) were associated with decreased IC but were not related to lowered arterial oxygen pressure or IV increase per millimeter of pupil miosis (IV/PD). These differences in anterior segment parameters were neither correlated with differences in IOP nor AMS.</p><p><strong>Conclusions: </strong>After short-term, effortless exposure to hypobaric hypoxia, pupil miosis occurred with widening of the anterior chamber angle and decreased IC.
