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.

Hypoglycemia promotes inner blood-retinal barrier breakdown and retinal vascular leakage in diabetic mice. Science Translational Medicine , 2025; 17 (796) DOI: 10.1126/scitranslmed.adq5355 Cite ...

which leads to overgrowth and leakage of blood vessels in the retina. Now, scientists have found that HIF plays a role in how the blood-retinal barrier breaks down during hypoglycemia. Researchers ...

This happens because high pressure causes blood vessels in the brain to expand, leading to pain and discomfort. If you experience headaches that don’t go away or happen often without a clear ...

It can feel like a pounding or throbbing pain, often in the back of the head. Why does this happen? High blood pressure puts extra strain on the blood vessels in your brain.

These changes include: Microaneurysms, small bulges in retinal blood vessels that may leak fluid or blood into surrounding tissues. These tiny vascular abnormalities represent the earliest ...

Systolic, the top number of a blood pressure reading, refers to the pressure within blood vessels during a heartbeat. “While blood pressure readings remained elevated at the end of this Phase II ...

This bleeding most commonly occurs in diabetic patients when abnormal retinal blood vessels rupture, though eye injuries and other conditions can cause similar bleeding. The resulting symptoms ...

Each 2.54 square centimetre (a square inch) of human skin has six metres (20ft) of blood vessels. Veins hold about 65 per cent of the body's blood and have one-way valves tohelp blood move.
