abstract = {Background: This study aimed to compare intraocular pressure (IOP) responses
during isometric handgrip strength tasks between primary open-angle glaucoma
patients and healthy individuals.
Methods: Forty older adults participated: 21 glaucoma patients and 19 controls. Participants randomly performed four trials at two intensities, maximal and submaximal (at
50% of self-perceived maximal effort), with two trials per hand (one for the left eye and
one for the right eye). IOP was measured immediately before exercise, during exercise,
and 5 seconds post-recovery. A four-factor mixed ANOVA was used to analyze IOP
responses, with task intensity and time of measurement as within-subject factors, and
group (glaucoma vs. control) and sex as the between-subjects factors.
Results: IOP responses were comparable between glaucoma patients and healthy
individuals, as the main effect of group (p = 0.117) and its interactions did not
reach statistical significance. The main effect of time reached statistical significance
(p = 0.016) due to greater IOP values during the task (17.3 ± 3.7 mmHg) compared
to pre-exercise (16.3 ± 3.2 mmHg: p < 0.001), but post-exercise IOP (16.9 ± 4.1
mmHg) was not significantly different from pre-exercise (p = 0.334) or during exercise
(p = 0.727). Greater IOP values were observed for the maximal task compared to the
submaximal task (p = 0.001), with no differences between men and women (p = 0.699).
Conclusion: Submaximal isometric strength training is a safe option for glaucoma
patients treated with hypotensive eye drops.},
