Spatial distribution of F-BUA. Comparison between both groups in a color-coded map with 168 small areas given by the Keratograph 5 M. In some eyes, several BUA broke simultaneously. Glaucoma patients showed more simultaneous BUA, that is, a bigger initial breakup area. Central location was more frequent in the glaucoma group. Scale from light green to red is represented as the frequency of F-NIBUT happening in each area. White areas: no breakup observed, either because no F-NITBUT was recorded in that area or because that area was not analysed by the device (e.g. shadows or premature blinking)
