New research from Duke Eye Center suggests loss of blood vessels in the retina could signal Alzheimer’s disease. On the left, the retina of a healthy person shows a dense web of blood vessels, the highest-density areas highlighted in red and orange. On the right, the retina of a person with Alzheimer’s disease shows areas in blue and teal where blood vessels are least dense. The images were captured using optical coherence tomography angiography (OCTA). The full study appears March 11 in the journal Ophthalmology Retina.
