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 ...

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.

Sudden vision blurring can occur due to various reasons like stroke, diabetic neuropathy, eye trauma, retinal detachment, and ...

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.

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, ...

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

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

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 ...

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.

As compared to the never users group, the HT user group presented significantly greater blood flow of the ITRA (P = 0.006), greater rim volume for the entire ONH region (P = 0.032), and greater ...

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.

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.
