Does retinal health affect Macular Pigment Optical Density (MPOD)? MPOD is typically lower in patients suffering from retinal health issues, and declines as average blood sugar (hemoglobin A-1-c) goes up. Many of these patients are also coincidentally affected by age-related eye health issues. While retinal health issues do not cause age-related eye health issues, the two share several risk factors.
One human study showed that supplementation with zeaxanthin and lutein increased MPOD and improved visual acuity, contrast, and foveal thickness. Zeaxanthin and lutein are powerful antioxidants that may help with:
- Contributors to unhealthy ocular conditions
- Oxidative stress
- Associated results
