BACKGROUND/AIMS Age-related macular degeneration (AMD) and vascular disease share similar risk factors. Recent data suggest AMD may independently predict stroke or coronary heart disease. We prospectively assessed the relationship between AMD and risk of stroke- or cardiovascular-related death in an Australian population. METHODS Of 3654 baseline(More)
PURPOSE To describe the distribution of retinal vascular calibers and their associations with ethnicity, gender, and birth parameters in children. METHODS This was a school-based cross-sectional study of 768 children aged 7 to 9 years who participated in the Singapore Cohort Study of the Risk Factors for Myopia (SCORM). Participants had retinal(More)
PURPOSE To examine the relationship between retinal vascular caliber and glaucoma in an Asian population. METHODS A population-based, cross-sectional study of 3019 persons of Asian Malay ethnicity aged 40 to 80 years residing in Singapore. All participants had dilated digital retinal photographs taken of both eyes. From these, retinal vascular caliber was(More)
OBJECTIVE Gestational diabetes mellitus (GDM) is an increasingly prevalent risk factor for the development of type 2 diabetes in the mother and is responsible for morbidity in the child. To better identify women at risk of developing GDM we examined sociodemographic correlates and changes in the prevalence of GDM among all births between 1995 and 2005 in(More)
OBJECTIVE Fractal analysis can quantify the geometric complexity of the retinal vascular branching pattern and may therefore offer a new method to quantify early diabetic microvascular damage. In this study, we examined the relationship between retinal fractal dimension and retinopathy in young individuals with type 1 diabetes. RESEARCH DESIGN AND METHODS(More)
BACKGROUND We assessed patient outcomes 90 days after hospital admission for stroke following a multidisciplinary intervention targeting evidence-based management of fever, hyperglycaemia, and swallowing dysfunction in acute stroke units (ASUs). METHODS In the Quality in Acute Stroke Care (QASC) study, a single-blind cluster randomised controlled trial,(More)
OBJECTIVE To describe retinal microvascular geometric parameters in young patients with type 1 diabetes. RESEARCH DESIGN AND METHODS Patients with type 1 diabetes (aged 12-20 years) had clinical assessments and retinal photography following standardized protocol at a tertiary-care hospital in Sydney. Retinal microvascular geometry, including arteriolar(More)
OBJECTIVE Alterations in retinal vascular caliber may reflect early subclinical microvascular dysfunction. In this study, we examined the association of retinal vascular caliber to incident retinopathy in young patients with type 1 diabetes. RESEARCH DESIGN AND METHODS This was a prospective cohort study of 645 initially retinopathy-free type 1 diabetic(More)
Retinopathy is the most common complication of diabetes. The assessment of retinopathy signs presents clinicians a unique opportunity to directly visualize and assess the actual morphology of diabetic microvascular damage. Extensive studies have now shown that people with diabetic retinopathy have excess risks of systemic vascular complications, including(More)
There is increasing evidence that the microcirculation plays an important role in the pathogenesis of cardiovascular diseases. Changes in retinal vascular caliber reflect early microvascular disease and predict incident cardiovascular events. We performed a genome-wide association study to identify genetic variants associated with retinal vascular caliber.(More)
