Longer moderate-to-vigorous physical activity duration is associated with better macular choroidal circulation in older adults with primary open-angle glaucoma
In a cross-sectional study of older adults with POAG, longer MVPA duration was independently associated with greater choroidal vascular volume (β = 0.04, P = 0.021) and higher choriocapillaris flow density (β = 0.06, P = 0.004). Patients with POAG had lower PA levels and reduced choroidal circulation compared to age-matched controls.

The Claim
Longer moderate-to-vigorous physical activity duration is associated with better macular choroidal circulation in older adults with primary open-angle glaucoma
This conclusion is most relevant to: Older adults aged 60 years or older with primary open-angle glaucoma and age-matched controls.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Physical Activity and Macular Choroidal Circulation in Older Adults With Primary Open-Angle Glaucoma: A Swept-Source Optical Coherence Tomography Angiography Study. (Translational vision science & technology, 2026) —
How It Works
The proposed biological pathway:
- ▸Physical activity increases systemic blood flow and shear stress
- ▸Improved endothelial function and nitric oxide bioavailability in choroidal vessels
- ▸Enhanced choroidal perfusion and vascular volume maintenance
- ▸Result: Better choroidal circulation in glaucoma patients with higher MVPA
Who Might Benefit
Evidence fit by population:
- ▸Older adults aged 60 years or older with primary open-angle glaucoma and age-matched controls
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Cross-sectional design prevents causal inference
- ▸Physical activity was self-reported and actigraphy-based, which may have measurement error
Frequently Asked Questions
What is the minimum amount of MVPA associated with better choroidal circulation?▼
The study did not specify a threshold; it analyzed MVPA duration as a continuous variable.
Can physical activity reverse glaucoma-related choroidal damage?▼
No, this cross-sectional study only shows an association, not causation or reversal.
Was the association seen in both POAG patients and controls?▼
The significant associations were reported specifically among patients with POAG, not in controls.
What type of physical activity counts as moderate-to-vigorous?▼
MVPA includes activities like brisk walking, jogging, or cycling that increase heart rate and breathing, as measured by actigraphy.
