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

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.

Retinal swelling that then occurs can cause blurred or cloudy vision. What's more, new abnormal blood vessels start to grow here. These are less resilient than the normal ones and leak even more ...

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 ...

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.

New blood vessels. Apart from diabetes, other conditions such as sickle cell disease , retinal vein occlusion, vasculitis (Eales disease and others), ocular ischemic syndrome, and retinopathy of ...
