We hypothesized that retinal vascular calibre would be altered in patients with RA, who are known to have both elevated cardiovascular risk and chronic, systemic inflammation. Methods: Retinal vascular calibre was measured from digital retinal photographs using computerized methods in 51 RA patients and 51 age- and gender-matched controls. Retinal vascular calibre was compared between RA and control patients with adjustment for relevant variables including cardiovascular risk factors and companion vessel calibre. The relationship between retinal venular calibre and inflammation was assessed by comparing controls and RA patients with high and lower disease activity. Results: Retinal venular calibre [mean (S.D.)] was significantly wider in RA patients than in controls [235.9 (24.6) vs 211.6 (21.0) μm, P||Source Title:||Rheumatology||URI:||http://scholarbank.nus.edu.sg/handle/10635/109607||ISSN:||14620324||DOI:||10.1093/rheumatology/keq428|
