Alzheimer’s disease learned how to diagnose eyes

Болезнь Альцгеймера научились диагностировать по глазам Retinal vessels and fundus may indicate disease.

Researchers from Duke University in Durham proposed a new method for diagnosing Alzheimer’s disease.

In particular, physicians invited to identify the disease by using eye exams, since the development of this adegeneration disease is accompanied by changes in the tiny blood vessels of the retina.

Scientists claim that their innovative non-invasive technology allows to determine not only the various signs of Alzheimer’s, but mild cognitive disorders, which increases the risk of the above diseases.

The second scientific work conducted by researchers in Medical center Chaim Sheba, confirms the statement of the team from Duke University.

Scientists used a technique called optical coherence tomography angiography (OCTA) to examine the relationship between the retina of the eye and Alzheimer’s disease.

OCTA technology allows ophthalmologists to examine each layer of the retina display and measure their thickness is non-invasive. The technique uses light waves to take photos of the retina.

In the first study, the researchers compared the retina of people with Alzheimer’s disease with patients suffering from cognitive disorders, and healthy volunteers.

Doctors say that people with dementia there is a decrease in blood vessels in the retina at the back of the eye. In addition, a specific layer of the retina was thinner in people with dementia than in patients with the disorder or in healthy participants.

The researchers believe that their diagnostic tool to scan of the eye will improve the lives of people who are predisposed to the development of Alzheimer’s disease.
