Abnormal Thickness of Ganglion Cell-Inner Plexiform Layer in Patients with Alzheimer's Disease and Mild Cognitive Impairment

A depletion of retinal ganglion cells and axons has been histologically observed in Alzhemier`s disease patients. Previous studies showed that retinal nerve fiber layer(RNFL) is reduced in Alzheimer's Disease (AD) and mild cognitive impairment (MCI) patients. The purpose of this study is to find the differences of Macular and Ganglion Cell-Inner Plexiform Layer thickness in AD, MCI, and control subjects
