摘要

Purpose

This study investigated the effects of isometric resistance exercises on intraocular pressure (IOP) and ocular perfusion pressure (OPP) in patients with primary open-angle glaucoma (POAG) and age- and sex-matched controls.

Methods

Twenty-five POAG patients (70.4 ± 6.8 years) and nineteen controls (69.2 ± 6.0 years) participated in this cross-sectional study. Participants performed mid-thigh pull and biceps curl exercises at low and high intensities. IOP was measured before-exercise, during exercise, and after 1 and 5 minutes of recovery. OPP was assessed before-exercise, and after 1 and 5 minutes of recovery.

Results

Both exercises caused a progressive increase in IOP (F = 65.2, p < 0.001, ƞ²p = 0.61), especially at high intensity (F = 103.6, p < 0.001, ƞ²p = 0.71), but IOP quickly returned to baseline afterward. POAG patients showed a significantly smaller IOP increase during the mid-thigh pull at high intensity (2.6 ± 0.8 mmHg) compared to the control group (5.1 ± 0.9 mmHg). A slight increase in OPP was observed after-exercise (F = 3.3, p = 0.048, ƞ²p = 0.07), with no differences after 5 min of recovery, suggesting temporary changes in ocular hemodynamics.

Conclusion

These findings suggest that while isometric exercises can elevate IOP temporarily, they may still be incorporated into training regimens for POAG patients if intensity is carefully managed. Careful monitoring of IOP is essential to avoid exacerbating glaucoma conditions during isometric exercises.
