[BDSP. Notice produite par INIST-CNRS 9GnBDR0x. Diffusion soumise à autorisation]. Retinal arteriolar narrowing is a marker of microvascular damage from elevated blood pressure. Between August 2004 and June 2006, the authors examined the association between retinal vascular diameter and chronic kidney disease in a population-based cohort of 3,280 community-dwelling adults of Malay ethnicity aged 40-80 years living in Singapore. Chronic kidney disease was defined as 1) an estimated glomerular filtration rate (eGFR) of17 mg/g for men and>25 mg/g for women. Retinal arteriolar and venular diameters were measured and summarized as central retinal arteriolar equivalent (CRAE) and central retinal venular equivalent (CRVE). Individuals with reduced CRAE were more likely to have chronic kidney disease than those with increased CRAE. After controlling for age, gender, education, smoking, diabetes, hypertension, body mass index, and total and high density lipoprotein cholesterol, the authors found the odds ratio comparing the smallest with the largest CRAE quartile to be 1.42 (95% confidence interval : 1.03,1.96 ; Ptrend=0.02) for eGFR of
