Abstract
PURPOSE: To examine the prevalence and risk factors of retinal arteriolar emboli, a risk predictor of stroke, in an Asian population. DESIGN: Population-based cross-sectional study. METHODS: Retinal emboli were ascertained from retinal photographs obtained from both eyes of 3,265 Asian Malays, aged 40 to 80 years, according to a standardized protocol. Risk factors were assessed from detailed standardized interviews, clinical examinations, and laboratory investigations. RESULTS: The overall prevalence of retinal emboli was 0.6% (95% confidence interval [CI], 0.58 to 0.62). A finding of retinal emboli was strongly associated with increasing age (P = .005, for trend), but age-stratified prevale..
