Book excerpt: There are increasing lines of evidence showing that neurodegeneration in Alzheimer’s disease (AD) and Parkinson’s disease (PD) is not limited to the brain but also occurs in the retina. Consequently, AD/PD patients can gradually develop vision problems. This neurological and ophthalmological disorder creates a pressing need for developing therapy to treat vision impairment in AD/PD. On the other hand, pathophysiological changes in the retina may reflect what might happen in the same diseases in the brain. Thus retinal studies may allow us to develop quantifiable measures for the diagnosis and prognosis of disease progression. Furthermore, parallel or early pathophysiological changes of the retina in AD/PD allow us to study retina-brain interactions.
