Diagrams of retinal abnormal grading decision-making. a The grading diagram for geometric features, and the abnormal grade is determined by the comparison result between the geometric features value of target image \(G_{tar}\) and the geometric features value of reference model \(G_{ref}\). b, c The diagrams for morphological features according to the different threshold sets
