Brief Summary:
A single-nucleotide polymorphism (SNP) analysis of DNA obtained from peripheral blood of the glaucoma patients and the normal control will be performed to find genetic marker for primary open angle glaucoma.

Condition or disease Intervention/treatment
Single-nucleotide Polymorphism (SNP) for Glaucoma Genetic: SNP analysis of the DNA

Detailed Description:
Unrelated Korean subjects who have primary open angle glaucoma were recruited in the current study. Genotyping for various SNP associated with POAG due to the linkage disequilibrium patterns is to be performed. Genotypes would be statistically compared between patients with primary open angle glaucoma and normal control subjects free of any eye diseases.
