An inverse correlation was found between enzymatic and non-enzymatic antioxidants such as: SOD and uric acid (r = –0.401, p = 0.005) (Fig. 4), GPx and TAS (r = –0.346, p = 0.016) in the exudative AMD patients, and between SOD and TAS (r = –0.568, p = 0.016) in the early AMD subgroup. The gene discussed is SOD1; the disease is age-related macular degeneration.
