The Claim
Individuals with primary open-angle glaucoma experience a greater reduction in intraocular pressure following aerobic exercise compared to healthy individuals, despite having smaller baseline Schlemm’s canal dimensions.
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.
People with primary open-angle glaucoma have a larger drop in eye pressure after aerobic exercise than people without the condition, even though their eye drainage channels are naturally smaller.
See the scientific wording
The magnitude of intraocular pressure reduction following aerobic exercise is greater in individuals with primary open-angle glaucoma than in healthy individuals, despite smaller baseline Schlemm’s canal dimensions in glaucoma eyes, suggesting a heightened IOP responsiveness to exercise in diseased eyes.
When a person exercises, increased blood flow raises pressure in the veins around the eye, which pushes fluid through the eye’s drainage channel. This pressure stretches the drainage channel wider, letting more fluid escape and lowering eye pressure. In people with glaucoma, the drainage channel starts narrower and has more resistance, so the same stretching from exercise opens it more dramatically, letting out much more fluid and lowering pressure more than in healthy eyes.
What the research says
1 studyPeople with glaucoma saw their eye pressure drop more after exercise than people without glaucoma — even though their eye’s drainage channels were smaller to start with. This means their eyes may be more responsive to the benefits of exercise.
