We examined the intraocular pressure responsiveness to oral examination stress, as well as the mediating role of the perceived levels of public speaking anxiety on intraocular pressure changes. Thirty-two university students (intervention group) publicly defended their degree final project, and intraocular pressure and perceived levels of stress were measured before and after the oral presentation, and after 10 min of recovery. The control group (n = 32) was not exposed to any stressful situation, and the dependent measures were taken at the same time points. All participants completed the public speaking anxiety scale. The intervention group exhibited higher intraocular pressure values before the oral presentation (corrected p-values<0.001), with these changes being positively associated with the perceived levels of public speaking anxiety (p < 0.001, r = 0.71). Our results reveal a mediating role of public speaking anxiety on the intraocular pressure responsiveness to oral examination stress, and highlight the utility of intraocular pressure as an indicator of stress in applied situations.

我们检查了眼内压对口腔检查压力的反应性，以及公众讲话焦虑水平对眼内压变化的中介作用。32名大学生（干预小组）公开辩护他们的学位最终项目，并在口头陈述前后，恢复10分钟后测量眼内压和感觉到的压力水平。对照组（n = 32）没有受到任何压力，并且在相同的时间点采取了相关措施。所有参与者均完成了公众演讲焦虑量表。干预组在口服前表现出较高的眼内压值（校正后的p值<0.001），这些变化与公众讲话焦虑的感知水平呈正相关（p <0.001，r = 0.71）。我们的研究结果揭示了公众演讲焦虑对眼压对口腔检查压力的反应性的中介作用，并强调了眼压作为实用情况下压力指标的效用。
