Fig. 13. This is an overview printout of three sequential fields during a 7-month period in a patient with glaucoma. All fields are of good reliability with few fixation losses (FL) or false-negative (FN) and false-positive responses (FP). When we compare the most recent field (bottom) with the initial examination (top), we see an overall increase in threshold sensitivities, particularly in the periphery, with patient experience.
