A Study of AMDX-2011P in Participants With Alzheimer's Disease

This study is testing a new non-invasive method called retinal imaging (taking detailed photos of the back of the eye) to detect early signs of Alzheimer's disease in people who already have a confirmed diagnosis. Changes in the retina may mirror what is happening in the brain. **You may be eligible if...** - You have a confirmed diagnosis of Alzheimer's disease with positive amyloid brain scan (PET) - You are willing to have a genetic test (APOE genotyping) - You are able to have detailed images taken of both eyes **You may NOT be eligible if...** - You have been diagnosed with glaucoma, or are suspected to have glaucoma - You have intermediate or advanced macular degeneration (AMD) in either eye - You have another significant eye condition that prevents valid retinal imaging - You have a medical or psychological condition that, in your doctor's opinion, makes study participation unsafe or unlikely to be completed Talk to your doctor to see if this trial is right for you.
