The intraocular pressure responses to oral academic examination: The influence of perceived levels of public speaking anxiety.

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.
