Researchers based at the Cedars-Sinai Medical centre in Los Angeles have demonstrated the detection of A-beta plaques in post mortem retinas from individuals suspected and confirmed to have Alzheimer’s disease. The study, led by Drs. Maya Koronyo-Hamaoui and Daniel L. Farkas, suggests that a non-invasive in vivo imaging of a hallmark of Alzheimer’s disease may be feasible through retinal imaging. Once validated in the retinas of live Alzheimer’s patients the technology may provide a significant clinical tool in assessing patients for diagnosis, monitoring and response to medical treatment.
