The research was adopted Duke University (OCTA), which allows doctors to quickly examine the blood flow in the small capillaries located at the back of the retina.
The main author of Sharon's study ideas: "We measure Blood vessels What can not be seen during a normal eye exam, and we do it using a relatively new and extensive technique that takes high resolution images of very small blood vessels from the retina in just a few minutes. ".
He added, "These changes are likely to reflect the density of the blood vessels retina What's going on in the micro-blood vessels of the brain, maybe before we can detect a change in perception? "
According to the site "New atlas" The study was conducted on more than 200 people, photographed using the technique OCTA. He found that 39 of them had an illness AlzheimerAnd 37 suffer from mild cognitive impairment (MCI).
One of the main goals of the study was to identify any damage to the retina that could be directly related to Alzheimer's disease, regardless of the general cognitive decline associated with aging.

Duke University's research on nonsurgical imaging, called OCTA, allows physicians to quickly examine blood flow in the small capillaries located at the back of the retina.
"We measure blood vessels that can not be seen during a normal eye examination, and we do this using a relatively new and extensive technique that takes high resolution images of very small retinal blood vessels." in just minutes, "said Sharon's senior author.
"These changes in the density of the retinal blood vessels may reflect what is happening in the microvascular brain, perhaps before we can detect changes in perception," he said.
According to the website "New Attlas", the study was conducted on more than 200 people, were filmed using the technique of OCTA. It was found that 39 people had Alzheimer's disease and 37 had a low cognitive impairment (MCI).
One of the main goals of the study was to identify any damage to the retina that could be directly related to Alzheimer's disease, regardless of the general cognitive decline associated with aging.
