What is it about?

The retina has been considered a window to the central nervous system (CNS). However, its use to discriminate between CNS disorders was never demonstrated. This paper demonstrates it by imaging the eye with optical coherence tomography (OCT).

Why is it important?

Our findings demonstrate the embedded information in the human retina about brain health/disease, particularly neurological diseases like Alzheimer's and Parkinson's. Moreover, that information helps discriminate between the two diseases.


We hope this article draws attention to these new perspectives on using the eye as a window to the CNS and on exploring information conveyed by optical coherence tomography besides thickness measurements.
