To evaluate the association profiles of the lysyl oxidase-like 1 gene polymorphisms with pseudoexfoliation syndrome in the Korean population, Genotypes of lysyl oxidase-like 1 gene were analyzed by direct sequencing.

To evaluate the association profiles of the lysyl oxidase-like 1 gene polymorphisms with pseudoexfoliation syndrome in the Korean population, peripheral blood sampling will be done from the patients with pseudoexfoliation.

And genotypes of the three single nucleotide polymorphisms of lysyl oxidase-like 1 gene , rs1048661, rs3825942, rs2165241 were analyzed by direct sequencing.

Inclusion Criteria:

• Clinical diagnosis of Pseudoexfoliation

Exclusion Criteria:

• medical condition that peripheral blood sampling cannot be done

the groups or cohorts will be recruited from glaucoma clinic in Samsung medical center
