A significant difference was observed between MD, PSD, s-RNFL and m-RNFL levels of groups (p\<0.05) (Table 3), but when compared with Groups of Vit E and AOF, MD and s-RNFL levels of the Group GB were significantly low and PSD level was significantly high in the same group. m-RNFL level of the Vit E group was significantly higher than m-RNFL levels of GB, AOF and Control groups (p\<0.05, p\<0.01). In the comparison of Vitamin E with GB, MD values were found significantly higher and PSD values were significantly low (p\<0.05). No statistically significant difference was present between I-RNFL levels of groups (p\>0.05). While the difference between c/d levels of groups were highly significant (p\<0.01) (Table 3), c/d levels of Vit E and GB groups were found significantly lower than c/d levels of AOF and Control groups (p\<0.01). c/d level of the Vit E group is significantly lower than c/d levels of AOF and Control groups (p\<0.01). No statistically significant difference was found between c/d levels of other groups (p\>0.05).
No statistically significant difference was present between s-GCC and i-GCC levels of groups (p\>0.05). A high statistically significant difference was found between m-GCC levels of groups (p\<0.01). While highly 201 significant and significant difference were present between m-GCC level of the Vit E Group and m-GCC levels of AOF and Control Groups, respectively, (p\<0.01, p\<0.05), m-GCC level of the Group GB was significantly higher than that of Group AOF (p\<0.05). No statistically significant difference was observed between m-GCC levels of other groups (p\>0.05).
