Retina layers segmented by deep learning (IMAGE) NIH/National Eye Institute Caption Spectral-domain optical coherence tomography uses light to image layers of the retina. Many scans taken over five years were analyzed using deep learning, a type of artificial intelligence in which imaging data are fed into an algorithm that learns how to detect patterns. Six retinal layers were segmented and analyzed for changes in thickness. Credit NEI Usage Restrictions No restrictions.
