Study design and workflow for Ai-Doctor development

The development of Ai-Doctor consisted of four steps: phase identification (A), disease diagnosis (B), segmentation of NPAs and BRVO areas (C), and CAII threshold exploration for laser therapy suggestion (D). AI, artificial intelligence; BRVO, branch retinal vein occlusion; CAII, clinically applicable ischemia index; CRVO, central retinal vein occlusion; DR, diabetic retinopathy; FFA, fundus fluorescein angiography; NPA, non-perfusion area; ResNet, residual network; ROC, receiver operating characteristic.
