Usual Distribution of Retinal Blood-Vessels

Mature Primate Retinal Blood Vessels

Purpose. To characterize developing retinal blood vessels with vascular markers and to relate the histochemical profile of maturing vessels to morphologic stages in retinal vascular development. Methods. Vessels were examined in frozen and paraffin-embedded retinas and in wholemounts of Macaca monkeys ranging in age from fetal day 75 (F75) to adulthood. Endothelial cells were visualized immunoh...

Direction-Based Segmentation of Retinal Blood Vessels

Using MAS to Detect Retinal Blood Vessels

The segmentation of retinal vasculature by color fundus images analysis is crucial for several medical diagnostic systems, such as the diabetic retinopathy early diagnosis. Several interesting approaches have been done in this field but the obtained results need to be improved. We propose therefore a new approach based on an organization of agents. This multi-agent approach is preceded by a pre...

Width Measurement from True Retinal Blood Vessels

A retinal image can establish the state of human body by simply providing the information about what is happening inside it. Because the AVR status of blood vessels is having good correlation with hypertension, coronary, heart disease and stroke. However they require the accurate extraction of distinct blood vessels and width measurement. The Existing width measurement techniques met with a cha...

Retinal blood vessels extraction using probabilistic modelling

The analysis of retinal blood vessels plays an important role in detecting and treating retinal diseases. In this review, we present an automated method to segment blood vessels of fundus retinal image. The proposed method could be used to support a non-intrusive diagnosis in modern ophthalmology for early detection of retinal diseases, treatment evaluation or clinical study. This study combine...
