Searching for the Spectral Signature of Alzheimer’s
Could a tri-spectral retinal imaging module offer new hopes for Alzheimer’s disease screening?
-
1
The retina is increasingly recognized as a potential indicator of neurodegeneration in Alzheimer's disease.
-
2
Researchers developed a tri-spectral retinal imaging module that integrates with existing fundus cameras for Alzheimer's screening.

The tri-spectral imaging captures retinal reflectance across blue, green, and red bands, enhancing sensitivity to Alzheimer's-related changes.
-
4
A blue-to-green ratiometric map revealed increased blue reflectance in Alzheimer's patients compared to healthy controls.
-
5
The tri-spectral imaging approach shows promise for non-invasive Alzheimer's screening, but larger studies are needed for validation.
