Probability of association between a visual field point and the optic disc. Probability of insertion around the optic nerve head for a visual field point 3 degrees to the right and 15 degrees above fixation in a right eye. The vertical lines indicate boundaries between the six standard sectors analyzed by the HRT. Calculating the area under the curve for each sector, the probability of this point being associated with the inferior-nasal sector is 26% and with the inferior-temporal sector is 74%.
