Brief Summary
The investigators would like to know if different imaging devices can improve the quality of images and visualization of imaged tissues. Also, the investigators would like to find out whether these changes are useful in the diagnosis and treatment of eye diseases. Using images of previous participants will allow us to demonstrate the advancement of different technologies, as well be used to allow comparisons between current technologies.

Age-related Macular Degeneration participants
Interventions
Nidek MP-3 device to be used to take images which will allow measurement of GA in patients with AMD
Eligibility Criteria
Cohort A will consist of patients with AMD, recruited by PI when they come in to the clinic, with whom we will conduct medical record review and imaging procedures, using one of the research devices. Cohort B will consist of control subject with no ocular problems, with whom no record review will be conducted, but imaging will be conducted with study devices.
You may qualify if:
- Normal, healthy participants and patients with AMD
You may not qualify if:
- Those suffering from head, neck or other injury which makes them unable to position themselves in head restraint for imaging
- Participants who are unable to maintain retinal fixation on a specified target
- Participants unable to achieve sufficient pupil dilation and alignment stability for imaging to take place
- Patients with media opacity which preclude high quality imaging will be excluded.
