High Levels of 17β-Estradiol Are Associated with Increased Matrix Metalloproteinase-2 and Metalloproteinase-9 Activity in Tears of Postmenopausal Women with Dry Eye
Figure 3
Correlation of 17β-estradiol levels with (a) tear MMP-2 concentrations (ρ = 0.67, ); (b) tear MMP-9 concentrations (ρ = 0.58, ); and (c) Schirmer test results (ρ = −0.58, ). Spearman’s rank correlation coefficients were calculated in 15 dry eye subjects who had detectable levels of 17β-estradiol.
