When comparing with the samples from the comparative subjects (constituted by those undergoing surgery for non-complicated cataracts), MDA/TBARS (p = 2.2 × 10−16), SOD (p = 2.2 × 10−16), GPx (2.2 × 10−16) and NO (6.5 × 10−10) displayed significantly higher values in the aqueous humor of POAG patients (Figure 2A,C,D,F). The gene discussed is SOD1; the disease is cataract.
