• Can I get a retinal scan now to see if I will develop Alzheimer’s?


    Question:

    I read about an OTCA retinal scan that is being worked on or researched to detect signs of Alzheimer’s disease. Is this something that is proven now and when will it be available for doctors to use in their practice? I have a family history of Alzheimer’s and want to be tested as soon as this is available.


    Answer:

    Given the increased prevalence of Alzheimer’s disease, there is considerable interest in finding a noninvasive method of diagnosing the disease earlier, before people begin losing their memory. Optical coherence tomography (OCT) and OCT angiography (OCTA) have been suggested as retina imaging technology that may play a role in detecting signs of this disease. However, at this point, the benefits of OCT and OCTA in Alzeihmer’s has not been proven and its potential benefit is uncertain.
