Fig. 6. Examples of ultra-widefield fundus images with an arrow/circle generated according to heatmaps.

Fig. 6

a The arrow towards the area of retinal detachment in image A1 is established automatically based on the highlighted region in heatmap A2. b The circle located at the centre of retinal detachment in image B1 is created automatically on the basis of the highlighted region in heatmap A2. The arrow/circle is used to instruct patients in preoperative posturing to reduce the progression of retinal detachment between detection and treatment. The dotted diagonal line in the image is used to divide the retina into four quadrants (superior, inferior, left, and right).
