Intraocular Pressure Response to Perceived Stress in Juvenile-onset Open-angle Glaucoma.

Prcis: High perceived stress from academic pressure is associated with intraocular pressure elevation and reduced fluctuation in juvenile-onset open-angle glaucoma patients. Personalized stress assessment and relief strategies may serve as an adjunct therapy in glaucoma.

Objective: To evaluate the effect of higher perceived stress, resulting from academic pressure, on intraocular pressure (IOP) in juvenile-onset open-angle glaucoma (JOAG) patients compared to healthy individuals.

Participants and methods: The study included 48 university students aged 18 to 27, comprising 24 JOAG patients on antiglaucoma eyedrops and 24 healthy controls. In an examiner-blind pretest-posttest design, participants' IOP was measured weekly using Goldmann tonometry during three follow-up visits at the beginning and end of the academic semester. Perceived Stress Scale (PSS) scores were also evaluated at these two time points to capture the contrast in perceived stress between periods of low and high academic pressure.

Results: Baseline PSS score at the semester's start was lower in both groups (14.1±1.9 in glaucoma vs. 13.5±2.4 in control) and significantly increased by the end of the semester (29.2±2.1 vs. 28.5±1.3; P<0.001), indicating increased perceived stress. Concurrently, IOP rose from 22.01±5.87 mmHg to 25.08±5.84 mmHg in the glaucoma group and from 11.36±2.03 mmHg to 13.65±2.11 mmHg in the control group. Factorial analysis revealed a significant interaction between stress and JOAG [F(1,94)=15.94, P=0.001], partial η2=0.08, with stress having a greater increase on IOP in the glaucoma group (+3.10 mmHg) compared to the control group (+2.23 mmHg) [t(94)=4.457, P<0.001].

Conclusions: Higher perceived stress significantly increases IOP, especially in JOAG patients, suggesting personalised stress management as a potential adjunct therapy for patients.
