Reflections on the Utility of the Retina as a Biomarker for Alzheimer's Disease: A Literature Review. [PDF]

open access: yes, 2019
As a part of the central nervous system, the retina may reflect both physiologic processes and abnormalities related to diseases of the brain. Indeed, a concerted effort has been put forth to understand how Alzheimer's disease (AD) pathology may manifest
