Deep Neural Network-Based Method for Detecting Central Retinal Vein Occlusion Using Ultrawide-Field Fundus Ophthalmoscopy

Figure 4

Representative ultrawide-field fundus images and corresponding heat maps. The ultrawide-field fundus image without central retinal vein occlusion (CRVO) (A), and its corresponding superimposed heat map (B); with CRVO (C), and its corresponding superimposed heat map (D). In the image without CRVO (A), the deep convolution neural network focused on the optic disc (blue), whereas in the image with CRVO (B), the model focused on the optic disc and on the retinal hemorrhages (blue) (D).
