Here are some studies showing changes in intraocular pressure (IOP) in response to stress.

Main Study: Psychological Stress and Intraocular Pressure in Glaucoma (2024)

Additional Studies On Stress and Elevated IOP

Conclusion:

Multiple lines of research – from controlled trials to real-life stress scenarios – demonstrate that psychological stress can cause a measurable rise in intraocular pressure. In glaucoma patients, an acute stressor (like the TSST) has been shown to spike IOP on the order of ~4 mmHg (Psychological Stress and Intraocular Pressure in Glaucoma - Ophthalmology Glaucoma), a significant jump that over 60% of stressed patients experienced. Healthy individuals also exhibit IOP increases under stress, though typically more modest (Can Psychologic Stress Elevate Intraocular Pressure in Healthy Individuals? - PubMed).

Sources: The primary study above was published in Ophthalmology Glaucoma in 2024 (See https://www.ophthalmologyglaucoma.org/article/S2589-4196(24)00131-5/fulltext and Stress Found to Increase IOP About 4mm Hg in Glaucoma Patients), with supporting evidence from studies in Ophthalmology Glaucoma (2020) (Can Psychologic Stress Elevate Intraocular Pressure in Healthy Individuals? - PubMed), Applied Ergonomics (2018 (Effect of examination stress on intraocular pressure in university students - PubMed), 2020 (The intraocular pressure responses to oral academic examination: The influence of perceived levels of public speaking anxiety - PubMed)), and BMC Ophthalmology (2019) (Acute emotional stress as a trigger for intraocular pressure elevation in Glaucoma | BMC Ophthalmology | Full Text). Each confirms that psychological stress can cause a notable uptick in intraocular pressure.
