Figure 9From: Automatic method of analysis of OCT images in assessing the severity degree of glaucoma and the visual field loss The impact of cup arrangement with respect to the disk on the values w g and w BGA . A summary of various typical cup arrangements relative to the disk and the effect of their size on the features w g (1), w g (2) and w g (3) as well as w BGA and, in addition, the values of the DDLS, have been shown. A change in the position of the cup centre of gravity relative to the disk is expressed by the feature w g (1). In turn, the feature w g (2) is a measure of the centricity of the cup edge distribution with respect to the disk. w g (3) is the mean value of the RNFL thickness deviation from the standard.Back to article page
