Figure 4.

Reconstructed images representing PAC and PACG eyes from selected mean values of latent variables of each group. Top row: mean values of ${\eta }_1\sim {\eta }_6$, middle row: tripled mean values of ${\eta }_1\sim {\eta }_6$, bottom row: tripled mean values of ${\eta }_4$. Left column: plain segmented images, middle column: difference map, right column: magnified difference map of the angle with approximate AOD500 marked with arrows. We can see that PACG eyes seem to have a narrower angle (top row, right column) which is more pronounced if we multiply latent variables by 3 (middle row, right column). However, there was no noticeable difference in the width of the angle regarding only ${\eta }_4$ (bottom row, right column). It implies that despite significant statistical difference between two disease groups in ${\eta }_4$, narrower angle in PACG is not a direct result of ${\eta }_4$ but rather a result of combination all latent variables.
