“Retinal nerve fiber layer thinning in [Alzheimer’s disease] has been hypothesized to occur because of retrograde degeneration of the retinal ganglion cell axons, and these changes have been suggested to occur even before memory is affected. There is also a suggestion that neuroretinal atrophy may occur as a result of amyloid-beta plaque deposits within the retina, although this hypothesis remains more speculative.”
