While AI shows promise in detecting Alzheimer's disease through retinal scans, claims of 93% accuracy are misleading. Studies indicate that AI can identify patterns in retinal images, which are extensions of the central nervous system, correlating with Alzheimer's. However, the "93% accuracy" figure is an AUC metric, with actual accuracies ranging from 82% to 89% depending on the study and equipment used. Furthermore, the large datasets cited were often for pretraining, with actual Alzheimer's training sets being much smaller, and the technology is still in proof-of-concept stages without FDA clearance.
