Microglial cell activation for the whole set of images measured with the automatic method (n = 1215) for the different groups of the study.

<p>White circles show the medians; box limits indicate the 25th and 75th percentiles; whiskers extend 1.5 times the interquartile range from the 25th and 75th percentiles; polygons represent density estimates of data and extend to extreme values. Values on the blue background refer to the number of microglial cells found in that layer; those on the yellow background represent the percentage of the area labeled with a reaction to Iba-1 (+). The extreme values (top 10 and bottom 10 results) were eliminated from each group. The number of samples for the each group after this elimination was 121 naïve, 116 contralateral, and 108 OHT eyes. (IPL: inner plexiform layer; NFL: nerve fiber layer; OHT: ocular hypertension; OPL: outer plexiform layer). <i>Used with permission from Barrow Neurological Institute</i>, <i>Phoenix</i>, <i>Arizona</i>.
