In the case of common myopia there has been one study in a Caucasian cohort that assessed selected SNPs in MMP1, MMP3 and MMP9 and found a positive association of myopia with the rs3025058 in MMP3 (p = 0.015) and the rs17576(R279Q) in MMP9 (p = 0.026) [15]. This evidence concerns the gene MMP9 and myopia.
