The Claim
The expansion of Schlemm’s canal following aerobic exercise does not consistently correlate with the magnitude of intraocular pressure reduction in either healthy individuals or those with primary open-angle glaucoma.
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.
When people exercise, the drainage channel in the eye sometimes widens, but this widening does not reliably match how much the eye pressure drops, regardless of whether they have glaucoma or not.
See the scientific wording
The expansion of Schlemm’s canal following aerobic exercise does not consistently correlate with the magnitude of intraocular pressure reduction in either healthy individuals or those with primary open-angle glaucoma, suggesting that other physiological mechanisms may contribute to IOP lowering.
When you exercise, your heart pumps more blood, which increases pressure in the veins around the eye. This pressure pushes fluid out of the eye more efficiently, and at the same time, the main drainage channel in the eye widens, letting more fluid escape. Together, these two changes lower the pressure inside the eye.
What the research says
1 studyExercise makes the eye’s drainage channel bigger and lowers eye pressure, but the bigger the channel gets, it doesn’t always mean the pressure drops more — so something else in the body is probably helping too.
