The Claim
A single 30-minute session of moderate-intensity aerobic exercise is associated with a 23% increase in Schlemm’s canal cross-sectional area and a 15% increase in diameter in both healthy eyes and eyes 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.
A 30-minute session of moderate aerobic exercise increases the size of Schlemm’s canal by 23% in cross-sectional area and 15% in diameter in both healthy eyes and eyes with primary open-angle glaucoma.
See the scientific wording
A single 30-minute session of moderate-intensity aerobic exercise is associated with a significant increase in Schlemm’s canal cross-sectional area by approximately 23% in healthy eyes and 23% in eyes with primary open-angle glaucoma, and an increase in diameter by approximately 15% in both groups, suggesting transient morphological changes in the ocular drainage pathway.
During moderate aerobic exercise, increased blood flow raises pressure in the veins around the eye, which pushes more fluid into the eye's drainage channel. This extra pressure stretches the drainage channel wider, allowing fluid to flow out faster and lowering eye pressure.
What the research says
1 studyAfter a 30-minute walk or run, the eye’s drainage channel gets about 23% wider and 15% larger in diameter in both healthy people and those with glaucoma, helping fluid drain out better.
