This trial is looking for adults with neurodegenerative diseases or no neurodegenerative disease. Participants will undergo imaging tests to assess their eye health.
Are You a Good Fit for This Trial?
You may be able to join if
I have a neurodegenerative disease
I do not have a neurodegenerative disease
You may not be able to join if
I cannot cooperate with tests or have other eye conditions affecting imaging
I have had eye surgery other than cataract surgery

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 qualifies will be included in the study.
