NEW YORK (Reuters Health) – "Major" differences in the retina of Alzheimer's disease patients can be identified, opening the way for a future in which the disease can be diagnosed by a simple eye exam before the onset of the main symptoms, according to a new study published in the journal Retina. Sky News. "
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 blood vessel density in the retina may reflect what is happening in the microcirculation of the brain, perhaps before we can detect any change in perception."
According to the site "New Attlas", the study was conducted on more than 200 people, were filmed using OCTA technology.
It was found that 39 people had Alzheimer's disease and 37 had a low cognitive impairment (MCI).
One of the main objectives of the study was to identify any retinal lesion that may be directly related to Alzheimer's disease, regardless of the overall cognitive decline associated with age. .
