An illustration of the experimental procedure. In total, 66 ophthalmologists participated in the experiment. All observers were instructed to select one of the possible retinal diseases after reviewing the given SD-OCT image. In step 1, only the SD-OCT image was provided without any AI advice (ie, No AI). In step 2, the decision probability provided by AI was displayed on the system (ie, AI Prob). Finally, in step 3, the visual evidence of the AI decision was provided in addition to the AI probability panel (ie, AI Prob+Evid). The AI model was trained, validated, and tested using 1389, 141, and 163 images, respectively. The experiment was conducted using 100 images randomly sampled from the test set. AI: artificial intelligence; AI Prob+Evid: artificial intelligence assistance with a probability score and visual evidence heatmap; AI Prob: artificial intelligence assistance with a probability score; No AI: without artificial intelligence assistance; SD-OCT: spectral domain optical coherence tomography.
