Brain-derived neurotrophic factor (BDNF) gene polymorphism in a cohort of Egyptian primary open-angle glaucoma (POAG) patients

Abstract

Correlation coefficient analysis showed significant positive correlation between age and right and left cup to disc ratio (r = 0.448, p = 0.001; r = 0.283, p = 0.004 respectively) and significant negative correlation between intraocular pressure and right and left VA (r = − 0.212, p = 0.034; r = − 0.258, p = 0.009 respectively). No significant difference between the 2 groups was found as regards genotype or alleles frequency distribution (p = 0.722).
