Heat maps generated using gradient weighted class activation map (Grad-CAM) for the model’s prediction on neovascular age-related macular degeneration (nAMD) recurrence. Grad-CAM visualized the pathologic regions most closely associated with the recurrence of nAMD on the four optical coherence tomography (OCT) images: a pre-injection image, OCT after first injection, OCT after second injection, and OCT after third injection.
