Retinal vessel diameter and cardiovascular mortality: pooled data analysis from two older populations.

AIMS The retinal microvasculature may reflect pre-clinical changes in the cerebral and coronary microcirculations. We assessed whether smaller retinal arterioles and larger venules predicted coronary heart disease (CHD)- and stroke-mortality. METHODS AND RESULTS We pooled data from the Beaver Dam Eye Study (n = 4926, aged 43-86) and the Blue Mountains Eye Study (n = 3654, aged 49-97). Retinal...

Retinal arteriolar emboli and long-term mortality: pooled data analysis from two older populations.

BACKGROUND AND PURPOSE To assess the relationship between retinal arteriolar emboli and mortality in older people. METHODS Pooled data from 2 population-based cohort studies. At baseline, the Beaver Dam Eye Study (BDES) examined 4926 persons 43 to 86 years of age (1988 to 1990), and the Blue Mountains Eye Study (BMES) examined 3654 persons 49 to 97 years of age (1992 to 1994). Retinal arterio...

Retinal Vessel Diameter Measurement Using Unsupervised Linear Discriminant Analysis

An automatic vessel diameter measurement technique based on linear discriminant analysis (LDA) has been proposed. After estimating the vessel wall, the vessel cross-section profile is divided into three regions: two corresponding to the background and one to the vessel. The algorithm was tested on more than 5000 cross-sections of retinal vessels from the REVIEW dataset through comparative study...

Blood vessel diameter Measurement on retinal Image

Accurate measurement of vessel diameters on retinal images plays an important part in diagnosing cardiovascular diseases and early signs of certain systemic diseases, such as diabetes and hypertension. In this study we develop new method based on computer aided to determine the width of retinal blood vessels by analysing the color fundus image. Retinal vessel diameter was measured based on bloo...

Retinal vein occlusion and vascular mortality: pooled data analysis of 2 population-based cohorts.

PURPOSE To assess the association of retinal vein occlusion (RVO) with cardiovascular and cerebrovascular mortality. DESIGN Pooled data from 2 population-based cohort studies. PARTICIPANTS At baseline, the Beaver Dam Eye Study (BDES) examined 4926 persons aged 43 to 86 years (from 1988-1990) and the Blue Mountains Eye Study (BMES) examined 3654 persons aged 49 to 97 years (from 1992 to 1994...
