Similarities of the whorl pattern between eyes. (A) Distance between eyes on the LDA graph for 67 patients where both eyes were available for analysis. (B) The intra-patient LDA distance is defined as the distance between both eyes of one patient, whereas the inter-patient LDA distance is between two eyes belonging to different patients. (C) The intra-patient distances for 67 patients are significantly smaller than the inter-patient distance tested on random combinations of the same 67 eye pairs. P < 0.001 Student t-test.
