[Association between optic disc hemorrhages and the position of central retinal vessels].
PURPOSE To investigate the correlation between optic disc hemorrhages (ODHs) and the position of the central retinal vessel trunk (RVT) in patients with glaucoma. METHODS Fundus photographs of 1,830 participants were reviewed. The exit position of the central retinal vessel trunk was classified as being in the superior or inferior hemisphere of the optic disc and the relative vertical positio...
متن کاملBallotini occlusion of retinal arteries. Collateral vessels.
IN a recent communication (Ashton and Henkind, 1965), the details of a method for embolizing retinal arteries in experimental animals were described, and a brief survey of the findings was provided. A most striking effect of arterial occlusion was the subsequent appearance of collateral vascular channels; these were predominantly arteriolar in nature, but in several instances anastomoses betwee...
متن کاملCollateral vessels reduce mortality.
Christian Seiler, Pascal Meier, and their co-workers of the University Hospital in Bern, Switzerland, well known for their pioneering clinical work on the collateral circulation of the heart, have described a meta-analysis of 12 studies involving 6529 patients of the role played by the collateral circulation in mortality. The authors come to the conclusion that the ‘coronary collateralization h...
متن کاملAutomated localisation of the optic disc, fovea, and retinal blood vessels from digital colour fundus images.
AIM To recognise automatically the main components of the fundus on digital colour images. METHODS The main features of a fundus retinal image were defined as the optic disc, fovea, and blood vessels. Methods are described for their automatic recognition and location. 112 retinal images were preprocessed via adaptive, local, contrast enhancement. The optic discs were located by identifying th...
متن کاملFeature selection for detection of new vessels on the optic disc
The development of new vessels on the retina of people with diabetes is rare, but is likely to lead to severe visual impairment. This paper investigates the selection of suitable image features for the automatic detection of new vessels on the optic disc. The features are chosen based on their discrimination capability (tested using the non-parametric Wilcoxon rank sum and Ansari-Bradley disper...
