Two weeks of OMT administration at a dose of 50 μl of 0.25% OMT led to significant increases in some of the antioxidant levels, such as CAT (p < 0.001, p < 0.001, p <0.001) and SOD (p < 0.001, p < 0.01, p < 0.001) when compared to the normal, glaucoma control, and standard groups, respectively, GPx (p < 0.001, p < 0.001) when compared to the glaucoma control and the standard groups, respectively, and GSH (p < 0.001, p < 0.001) when compared to the normal and standard groups, respectively, but with no significant variations from the glaucoma control group. This evidence concerns the gene CAT and glaucoma.
