Objective:
To investigate the relationship between intraocular pressure (IOP), systolic blood pressure (BP), and heart rate (HR) during aerobic exercise in glaucoma patients.
Key Findings:
- IOP increased with exercise intensity, peaking at 18.0±1.3 mmHg at 75 W.
- Post-exercise, 8 out of 10 participants showed IOP levels below baseline.
- Strong correlation between IOP and systolic BP (R² = 0.997) and HR (R² = 0.986) during exercise.
- No significant correlation between IOP and diastolic BP.
- IOP dropped more rapidly than BP or HR after exercise cessation.
Interpretation:
The findings suggest a potential common factor influencing IOP, BP, and HR, possibly linked to sympathetic nervous system activation. Increased IOP during exercise may not be harmful if offset by improved ocular perfusion pressure.
Limitations:
- Small study cohort and varied glaucoma stages.
- Short exercise duration may have missed complete IOP dynamics.
- Lack of healthy control participants.
Conclusion:
Future studies should involve larger, more homogenous samples and longer observation periods to enhance understanding of IOP regulation during physical activity.
