Retinal Abnormalities in Early Alzheimer's Disease -- Berisha et al. 48 (5): 2285 -- Investigative Ophthalmology & Visual Science

From the paper:

There is evidence suggesting that visual disturbances in patients with Alzheimer’s Disease (AD) are due to pathologic changes in the retina and optic nerve, as well as to higher cortical impairment.

Conclusion: Retinal abnormalities in early AD include a specific pattern of RNFL loss, narrow veins, and decreased retinal blood flow in these veins.
