APOE and open-angle glaucoma: For APOE polymorphisms, these parameters were similar in ε2ε3 and ε3ε3, with no statistically significant differences, whereas POAG subjects with the ε2ε3 genotype had worse visual field defects (median PSD=2.2) than those with the ε3ε4 genotype (median PSD=1.77; p=0.01) and POAG subjects with the ε3ε3 genotype had worse MD and PSD values (median= -7.4 and 3.4, respectively) than those with the ε3ε4 genotype (median= -4.1 and 1.77, respectively; p=0.034 and 0.028, respectively).
