Researchers have revealed that the retina, or the light-sensitive layer at the back of the human eye, includes a complex network of blood vessels that can predict critical elements about a person’s risk of stroke, according to what was published by the website health and me.
Researchers from the University of California conducted a study in this discovery of a non-invasive approach to predicting stroke, thus challenging the reliance on classic risk factors alone, such as high cholesterol or blood pressure.
The results of the study revealed that, by examining the retina, it is possible to predict the possibility of a stroke with accuracy comparable to traditional methods. These indicators include characteristics such as the density and complexity of the retinal veins and arteries, which reflect the vascular structure of the eye.
Signs appear on the retina
The researchers used advanced machine learning models, such as the Retinal Microvascular Health Assessment System, to study 30 indicators in 5 major classes of retinal vascular structure, and by examining the blood vessels within them they are anatomically and physiologically similar to the brain. Given this, they constitute an attractive organ for understanding the health of the body’s blood vessels, as many diseases that damage blood vessels throughout the body leave clues in the retina’s microvascular network.
