Thirty-four eyes of 26 glaucoma patients (mean age, 55.1 years) were examined. The pattern deviation (85th percentile) of pupil fields was calculated from the difference between age-matched normal and abnormal percentage pupil constriction. Consequently, glaucomatous damages were remarkably distinguished from the normal pupil fields using the pattern deviation of the imo.Keywords: pupil field, glaucoma, pattern deviation
