Higher levels of moderate and moderate-vigorous physical activity are associated with accelerated thickening rates of the ganglion cell-inner plexiform layer (GCIPL) and macular thickness (MT) across the full course of diabetic retinopathy, suggesting a neuroprotective structural benefit.
Regular exercise helps preserve the physical structure of your retina. Studies show that higher activity levels are linked to better maintenance of retinal layer thickness, which is crucial for preventing vision loss in diabetes. This structural benefit works alongside the risk reduction from morning exercise timing.
Higher MPA and MVPA were correlated with accelerated thickening rates of the GCIPL and MT sublayers, ranging from Pre-DM to those with established DR.

More from this paper
- Moderate-to-vigorous physical activity (MVPA) performed during morning hours (06:00–12:00) significantly reduces the risk of developing diabetic retinopathy (DR) and slows retinal thinning, whereas late-night physical activity increases DR risk.Good
- Body Mass Index (BMI) partially mediates the protective effect of physical activity on diabetic retinopathy, accounting for 35.7% to 58.7% of the total benefit, indicating that weight loss is a significant but not exclusive mechanism.Good
