Abstract
Peripheral visual field deficits developed through glaucoma have been shown to contribute to balance deficits and a fear of falling. Currently, there is no work that examines the relationship between fear of falling and quiet stance among glaucoma patients. Therefore, this study aimed to examine the impact of a virtual height-induced postural threat on balance control among healthy individuals exposed to a simulated glaucoma impairment. Participants stood on a force plate to measure kinetic responses while wearing a virtual reality (VR) head-mounted display (HMD) which also tracked head position. Surface electromyography (EMG) was also used to measure muscle activity from ankle stabilizing muscles. Trials were 60 s, with two at ground level and two at 7 virtual meters above ground, each exposing participants to normal vision and a VR-simulated glaucoma impairment. Electrodermal activity was collected, and questionnaires were completed following each trial to evaluate psychological aspects of the postural threat. Overall, while experiencing height-induced fear with normal vision, participants developed a tighter control of upright stance (decreased amplitude and increased frequency of balance-related movement); however, this was not observed for the simulated glaucoma conditions. Therefore, balance deficits among glaucoma patients may be mediated by fear of falling contributing to an unexpected postural strategy.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
