The results of Chakrabordy et al., like the current study, showed significantly lower serum Zn (Mcataract group = 0.64 mg/L, Mcontrol group = 0.97 mg/L, p < 0.05) and SOD concentrations in the cataract group in comparison to the controls (Mcataract group = 3.28 U/mL, Mcontrol group = 4.06 U/mL, p < 0.001) [27]. Here, SOD1 is linked to cataract.
