This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography (OCT) and OCT angiography (OCTA) as well as ultra-widefield (UWF) fundus photography to assess the structure and function of the retinal and choroidal microvasculature and structure in persons with mild cognitive impairment (MCI) and Alzheimer's Disease (AD), Parkinson's Disease (PD), or other neurodegenerative disease, diseases as outlined.
Using a multidisciplinary approach, this study aims to yield new insight into the vascular and structural pathophysiology of neurodegenerative disease. The investigators propose to develop and evaluate imaging biomarkers from OCT, OCTA, and UWF fundus photos to assess the structure and function of the retinal and choroidal microvasculature and structure in these individuals. The investigators hypothesize that microvascular and structural network alterations in the retina and choroid may mirror and possibly precede changes in the cerebral microcirculation seen in these neurodegenerative diseas…
Inclusion Criteria: * Adults with neurodegenerative disease ((MCI, PD, AD, FTD, DLB, ALS, MS, HD, TBI, concussion, PTSD and other neurodegenerations as well as Down Syndrome) * Adults without neurodegenerative disease Exclusion Criteria: * Inability to cooperate with or complete testing or other neurologic or age- related ocular conditions that would impact image acquisition. * Eyes that have had intraocular surgery, other than cataract surgery. If two eyes satisfy the inclusion criteria, both eyes will be included in the study. If one eye satisfies the inclusion criteria, the eye that qua…
