The segmentation of retinal blood vessels can be done using a variety of techniques and procedures. Unsupervised methods and supervised methods are the two types of procedures that are commonly used. A thorough examination of different unsupervised and supervised blood vessel segmentation approaches is ...
retinal hypoxia, which is a known potent stimulus to the dilation of retinal veins; venous stasis, which contributes to capillary engorgement, increased fragility and resulting bleeding; angiospasm, a spasmodic contraction of the blood vessels with increased blood ...

Basically, diabetes is a disease of blood vessels. With large amounts of glucose coursing through the circulatory system, a glycosylation reaction occurs between the sugar and the proteins that make up the vessel walls. Over time, this glycosylation promotes denaturing of collagen protein within the...
For this study, we tested the hypothesis that the headward fluid shifts associated with SANS and Head-Down-Tilt (HDT) bed rest, a well-established microgravity analog, are mediated at least in part by retinal blood vessels. The hypothesis further predicts that retinal vascular response occurs pr...

This usually occurs due to atherosclerosis (thickening) of retinal arteries that subsequently compress the vein as both vessels are inside the same sheath and run together. This blockage of blood flow is like having a “stroke” inside the eye. Damage to the retina includes bleeding, macular ...

it extracts a chemical substance called vasoformative. This substance leads to the growth of new blood vessels to prevent from loss of oxygen, which is dangerous. The new blood vessels are fragile, feeble, and are in form of bundles so theybleed. Thebleedingcreates clothes on the retina, whi...
blood vessels or regressing abnormal blood vessel growth, which can help reduce the risk of vision loss in those patients. This treatment can also be used to treat areas of the retina that are thinned or torn thereby reducing the risk of progression to retinal detachment as well as to seal ...
