Microglial cell distribution for the automatic and manual methods.

<p>Mean±SD are shown for the three study groups, both for the manual and the automatic methods in the IPL (A) and OPL (B). (C) Distribution of the glial cell populations for the automatic and manual methods. In this plot, 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, and polygons represent density estimates of data and extend to extreme values. (IPL: inner plexiform layer; OHT: ocular hypertension; OPL: outer plexiform layer). <i>Used with permission from Barrow Neurological Institute</i>, <i>Phoenix</i>, <i>Arizona</i>.
