Automated Grading of Diabetic Retinopathy with Ultra-Widefield Fluorescein Angiography and Deep Learning

Figure 3

Comparison of the UWFA and simulated 7-SF. (a) UWFA showed wider retina than simulated 7-SF in the normal eye. (b) UWFA image on the early phase showed more nonperfusion in the peripheral retina than simulated 7-SF in the NPDR eye (upper), and more peripheral leakage was found on UWFA image than simulated 7-SF on the late phase (bottom). (c) UWFA image on the early phase showed more nonperfusion and neovascularization in the peripheral retina than simulated 7-SF in the PDR eye (top), and more peripheral leakage was found on UWFA image than simulated 7-SF on the late phase (bottom).
