Age-Related Macular Degeneration Is Associated with Less Physical Activity among US Adults: Cross-Sectional Study.
We have a limited understanding of the effects of age-related macular degeneration (AMD) on physical activity (PA), and we have no prevalence estimates of the daily movement patterns among Americans with AMD. Therefore, we examined the association between AMD and PA and provided estimates of the dai...
