Researchers at Rutgers University are using specialized imaging to examine tiny blood vessels in the white of the eye, according to preliminary findings reported by the research team. The team paired this eye imaging with MRI brain scans in older adults. Older adults with mild cognitive impairment showed more abnormalities in these vessels compared to participants with normal cognitive function, the researchers said.
The eye and brain share similar small blood vessel structures, making the eye a potential window into brain health, according to researchers. Other research supports this connection. According to research published in JAMA Ophthalmology, as vision worsens with age, so too may cognitive abilities [2]. Additionally, McMaster University researchers found that retinal blood vessels reflect heart disease risk and biological aging [8]. The findings from Rutgers have not yet been peer-reviewed, the team noted.
