The Claim
In patients with primary open-angle glaucoma using prostaglandin eye drops, a single session of moderate-intensity aerobic exercise (20% Wmax for 10 minutes) reduces intraocular pressure by an average of 2.37 mmHg, and a single session of high-intensity aerobic exercise (60% Wmax for 5 minutes) reduces intraocular pressure by an additional 5.95 mmHg compared to moderate-intensity exercise, indicating that exercise intensity directly influences the magnitude of acute intraocular pressure reduction.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In people with primary open-angle glaucoma who use prostaglandin eye drops, 10 minutes of moderate aerobic exercise lowers eye pressure by 2.37 mmHg, and 5 minutes of high-intensity aerobic exercise lowers it by an additional 5.95 mmHg compared to moderate exercise.
See the scientific wording
In patients with primary open-angle glaucoma using prostaglandin eye drops, a single session of moderate-intensity aerobic exercise (20% Wmax for 10 minutes) reduces intraocular pressure by an average of 2.37 mmHg, and high-intensity exercise (60% Wmax for 5 minutes) further reduces it by an additional 5.95 mmHg, suggesting that exercise intensity directly influences acute IOP lowering.
When a person exercises, their heart beats faster and they sweat more, which makes the blood thicker with proteins. This thicker blood pulls fluid away from the eye, so the eye makes less of the fluid inside it. Less fluid inside the eye means lower pressure in the eye. The harder the exercise, the more the heart beats and the more the blood thickens, so the pressure drops even more.
What the research says
1 studyFor people with glaucoma using eye drops, a short, easy bike ride lowers eye pressure a little, and a short, harder bike ride lowers it even more — and the study proves this happens exactly as described.
