Abstract

PURPOSE: To describe the relationship of retinal vascular caliber with cardiovascular risk factors in an Asian population. METHODS: The Singapore Malay Eye Study is a population-based, cross-sectional survey that included 3280 (78.7% response) persons aged 40 to 80 years. Retinal vascular caliber was measured from digital retinal photographs using a validated standardized protocol. Data on major cardiovascular risk factors were collected from all participants. RESULTS: Of the 3019 participants with retinal vascular caliber data available, the mean retinal arteriolar caliber (CRAE) was 139.5 +/- 15.7 microm (SD), and mean venular caliber (CRVE) was 219.3 +/- 22.2 microm (SD). Smaller retinal ..
