IT is well known that the shadows of the retinal blood-vessels may be seen if a pinhole is held in front of the eyes near to the anterior focus and moved from side to side. They are also sometimes ...

The researchers found that a protein called hypoxia-inducible factor (HIF) builds up in retinal cells during episodes of low ...

New research has found that the endothelial cell-specific A disintegrin and metalloproteinase domain-containing protein 10 ...

Retinal vein occlusion is usually caused by a blood clot blocking the vein. But a nearby artery can sometimes be the problem. Arteries and veins cross over each other in the retina.

Kenichi Toma, PhD, labeled the retinal neurons closest to the blood vessels with a protein that glows green under ultraviolet light so he could observe the lattice as it was forming.

Diabetic Retinopathy results from damaged retinal blood vessels due to high blood sugar, leading to blurred vision and potential blindness. AMD, common in older adults, affects central vision, ...

Branch retinal vein occlusion (BRVO) is when a blockage forms in the veins branching off the retina, which can disrupt blood flow. Treatment depends on the type of blockage and severity of the damage.

Researchers are planning future studies on HIF, the breakdown of the blood-retinal barrier and 32-134D, and hope to conduct clinical studies of 32-134D in patients with diabetic retinopathy.

Features of the retinal blood vessel network can point to diabetic retinopathy, as well as other eye and cardiovascular diseases—even atherosclerosis. However, manual image segmentation is very ...

High blood pressure, also known as hypertension, can be caused due to high salt intake, chronic stress, and more, damaging ...

Retinal vein occlusion develops when blood vessels carrying blood from the retina become blocked. This blockage can cause sudden vision changes and requires immediate medical attention.

In the Arnall Patz Lecture, Richard F. Spaide, MD, discussed advancements in modern OCT technology that allow for the measurement of blood flow velocity in retinal blood vessels.
