It is important to mention that a significant and weak negative correlation was obtained between SOD and the age of patients in the whole group of AMD (r = –0.285, p = 0.012) (Fig. 5), while a stronger correlation was found in the subgroup of exudative AMD (r = –0.405, p = 0.005). The gene discussed is SOD1; the disease is age-related macular degeneration.
