(A) False positives—distribution of the number of lashes considered to be touching from images, when no lashes were identified as touching by field grading. (B) False Negatives—distribution of the number of eyelashes touching the globe in cases of trichiasis confirmed on field grading, which were classified as not having trichiasis in the image grading (2D and 3D).
