A recent study published in Ophthalmology Science presents evidence that chronic kidney disease (CKD) may causally contribute to age-related macular degeneration (AMD). Analyzing data from over 430,000 individuals in the UK Biobank over a decade, researchers found that patients with CKD had a significantly heightened risk for developing advanced AMD. The study employed Mendelian randomization to demonstrate that lower genetically determined kidney function is linked to a twofold increase in AMD risk. Findings suggest AMD should be viewed as a systemic disease, enhancing the need for targeted screening in CKD patients.
