The intensity of immunolabeling for AGEs and RAGE was first qualitatively graded as negative (−), faint (+), moderate (++), and strong (+++). Immunolabeling was then quantitatively graded on digitized images in a masked fashion by measuring the specific immunolabeling areas. A percentage value was expressed for each slide relative to the average ratio of the total area analyzed. Mean values are presented. Immunolabeling for AGEs and RAGE were qualitatively and quantitatively greater in the eyes of donors with glaucoma than in those of age-matched controls. Age-matched control data shown do not include four control eyes of donors younger than 55 years for appropriate age matching (38 glaucomatous vs. 26 control eyes).
