The results of the region of interest (ROI) separation in the polar coordinate presented in Cartesian coordinate system. The present region of interest is the basis for further analysis related to the determination of the features associated with the area change in the RNFL thickness and the percentage of the area cup/disk ratio. These features are the basis for determining their correlation with the results of perimetry. The areas TE, SU, NA, IN denoting the following areas respectively: temporal, superior, nasal, inferior have been marked on the axis θ. The cup boundaries are marked in red and disk boundaries in green.
