Serum Cystatin C Level, Kidney Disease Markers, and Incidence of Age-Related Macular Degeneration

Abstract
The finding of a relationship of complement factor H Y402H (1277T→C)genotype status to both age-related macular degeneration (AMD) and kidney disease (membranoproliferative glomerulonephritis type II and hemolytic uremic syndrome) has led to speculation that kidney disease might be associated with AMD.1-16Furthermore, many factors associated with chronic kidney disease (CKD) such as oxidative stress, inflammation, and endothelial dysfunction have been hypothesized to have a role in the pathogenesis of AMD.17-24However, there are few and inconsistent epidemiological data about the relationship of CKD to AMD.25-27
