“…The heart rate diVerence between trials in the present study is a result of the dehydration experienced (Sawka and Coyle 1999). Other researchers have observed no relationship between heart rate and intraocular pressure (Karabatakis et al 2004). Whilst the current study cannot exclude the possibility that body temperature and heart rate inXuence the intraocular pressure, the scientiWc literature does not support an association.…”

The aim of this study was to determine the intraocular pressure response to differing levels of dehydration. Seven males participated in 90 min of treadmill walking (5 km h(-1) and 1% grade) in both temperate (22 °C) and hot (43 °C) conditions. At baseline and 30 min intervals intraocular pressure, nude body mass, body temperature and heart rate were recorded. Statistically significant interactions (p < 0.05) were observed for intraocular pressure (hot condition: baseline 17.0 ± 2.9, 30 min 15.6 ± 3.5, 60 min 14.5 ± 3.7 and 90 min 13.6 ± 2.9 mmHg; temperate condition: baseline 16.8 ± 2.7, 30 min 16.5 ± 2.6, 60 min 15.8 ± 2.5 and 90 min 15.7 ± 1.8 mmHg) and body mass loss (hot condition: 30 min -1.07 ± 0.35, 60 min -2.17 ± 0.55 and 90 min -3.13 ± 0.74%; temperate condition: 30 min -0.15 ± 0.11, 60 min -0.47 ± 0.18 and 90 min -0.78 ± 0.25%). Significant linear regressions (p < 0.05) were observed for intraocular pressure and body mass loss (adjusted r(2) = 0.24) and intraocular pressure change and body mass loss (adjusted r(2) = 0.51). In conclusion, intraocular pressure was progressively reduced during a period of exercise causing dehydration, but remained relatively stable when hydration was maintained. The present study revealed a moderate relationship between dehydration (body mass loss) and intraocular pressure change.

“…Previous studies have shown a reduction in IOP following different types and intensities of exercise [1], [2], and it has been suggested that all forms of physical exercise such as bicycling, walking and jogging, decrease IOP [3], [4]. In normal subjects, the intraocular pressure decreases during exercise proportional to the work load [5].…”

The Short-Term Effects of Exercise on Intraocular Pressure, Choroidal Thickness and Axial Length

et al. 2014

PurposeTo explore ocular changes in healthy people after exercise.MethodsTwenty five volunteers underwent exercise for 15 minutes on a treadmill. Measurements of choroidal thickness, intraocular pressure (IOP), ocular biometry, and blood pressure were taken before and after exercise. Enhanced Depth Imaging optical coherence tomography (EDI-OCT) was used to measure choroidal thickness at the fovea. Intraocular pressure (IOP) was measured by Goldmann applanation tonometry. Ocular biometric measures were collected using A scan ultrasound. Blood pressure was measured concurrently with the acquisition of the scans.ResultsTwenty five volunteers (25 eyes) with a mean age of 25.44±3.25 years were measured. There was a significant increase in systolic and diastolic pressure after exercise (P<0.05). The IOP showed a significant decrease after exercise (P<0.05). However there was no significant difference in the mean choroidal thickness, ocular axial length, anterior chamber depth, lens thickness, or vitreous length before and after exercise measurements (P>0.05).ConclusionThere was a significant decrease in IOP from exercise without a change in choroidal thickness and ocular biometric measures. IOP and choroidal thickness were not correlated, suggesting that the IOP decrease from exercise is not due to changes in choridal thickness.

“…IOP decreases transiently with aerobic exercise in proportion to intensity and duration [2,9,15,24]. Running has been shown specifically to acutely decrease IOP [13] in proportion to its intensity [16]. There are also several studies suggesting that exercise training may chronically reduce IOP: one showing an IOP difference of 1.1 mm Hg ( P < 0.05) at the end of a 10-wk aerobic conditioning program compared with maintained sedentary lifestyle [31]; two others reporting additional 0.93- and 1.1-mm Hg IOP reductions in subjects participating in a 3-month supervised exercise program versus nonparticipating controls [27,28]; and an uncontrolled study suggesting that IOP decreased 4.6 mm Hg after 3 months of aerobic conditioning and returned to baseline levels once training ended [23].…”

Purpose To assess the dose–response relationship of vigorous physical activity (running distance, km/d) or cardiorespiratory fitness (meters-per-second pace during a 10-km footrace) to the risk for incident glaucoma. Design Prospective epidemiologic cohort study. Methods Participant-reported, physician-diagnosed incident glaucoma was compared with distance run per week and 10-km footrace performance in a cohort of 29,854 male runners without diabetes followed prospectively for 7.7 yr. The survival analyses were adjusted for age, hypertension, current and past cigarette use, and intakes of meat, fish, fruit, and alcohol. Results Two hundred incident glaucoma cases were reported during follow-up. The risk for reported glaucoma decreased 37% per meter-per-second increment in a 10-km race performance (P = 0.005). Relative to the least fit men (i.e., slowest, ≤ 3.5 m/s), the risk for incident-reported glaucoma declined 29% in those who ran 3.6–4.0 m/s (P = 0.06), 54% for those who ran 4.1–4.5 m/s (P = 0.001), 51% for those who ran 4.6–5.0 m/s (P = 0.04), and glaucoma was nonexistent among the 781 men who exceeded 5.0 m/s (P = 0.03). The risk for incident, reported glaucoma decreased 5% per kilometer-per-day run at baseline (P = 0.04), which remained significant when adjusted for the 10-km race performance (5% reduction per kilometer-per-day, P = 0.04), and both body mass index and race performance (P = 0.04). Baseline hypertension was unrelated to the incident glaucoma. Conclusions These data provide preliminary evidence that vigorous physical activity may reduce glaucoma risk, which, in the absence of medical record validation, could represent ocular hypertension in addition to frank glaucoma. Additional follow-up with validation is needed to identify the type of glaucoma affected.
