"Changes in the retinal vasculature may identify patients in the earliest stages of Alzheimer's disease, possibly well before the first symptoms appear, according to two studies reported here.
One study showed that patients with Alzheimer's disease had significantly reduced macular vessel density (VD) and perfusion density (PD) as compared with patients who had mild cognitive impairment (MCI) and with a group of healthy volunteers. The second study, involving participants in an Israeli registry of familial Alzheimer's disease, showed associations between brain-scan results, cognitive function, and retinal vasculature in asymptomatic individuals with a family history of Alzheimer's disease."
