Recent research from the Istituto Italiano di Tecnologia in Rome highlights a significant advancement in Alzheimer's disease (AD) diagnosis through a novel tri-spectral retinal imaging technique. This method integrates with existing fundus cameras to create an optical biomarker for AD, capturing retinal data across blue, green, and red wavelengths. In a study involving patients with mild AD and healthy controls, the technology demonstrated promising results by highlighting differences in retinal reflectance. Though initial findings are encouraging, further validation is required.
