Abstract
Purpose: To evaluate the association between chronic kidney disease (CKD) and early age-related macular degeneration (AMD) and peripheral retinal drusen in Korean adults 50 years and older.
Methods: This study included 3008 participants aged 50–87 years. Early AMD was assessed from retinal photographs based on modified Wisconsin AMD grading system and peripheral retinal drusen were assessed with a standardized examination. We defined CKD as estimated glomerular filtration rate of 60mL/min/1.73m2 and below according to the Modification of Diet in Renal Disease equation. Logistic regression was used to examine the association between early AMD, peripheral retinal drusen, and CKD.
Results: There were 88 subjects with early AMD and 42 subjects with peripheral retinal drusen. After adjusting for age, gender, body mass index, smoking status, hypertension, and diabetes mellitus, a significant association was found between CKD and peripheral retinal drusen as well as early AMD. Subjects with CKD were more likely to have early AMD (OR, 1.68; 95% CI, 1.04–2.72) and peripheral retinal drusen (OR, 2.01; 95% CI, 1.02–3.99) than those without CKD.
Conclusions: CKD was associated with peripheral retinal drusen as well as early AMD in Korean adults 50 years and older.
