<P>To investigate the underlying genetic influences of primary glaucoma in Korea, molecular analysis was performed in 112 sporadic cases, and results compared with healthy controls. The <I>myocilin</I> (<I>MYOC</I>) and <I>optineurin</I> (<I>OPTN</I>) genes were directly sequenced in 112 unrelated patients, including 17 with primary open-angle glaucoma, 19 with juvenile open-angle glaucoma, and 76 with normal tension glaucoma. Healthy unrelated Korean individuals (n=100) were used as the non-selected population control. A total of three <I>MYOC</I> and four <I>OPTN</I> variants potentially associated with primary glaucoma were identified in 4 and 18 patients, respectively. A novel variant of <I>MYOC</I>, <I>p.Leu255Pro</I>, was predicted to be potentially pathogenic by <I>in silico</I> analysis. Another, <I>p.Thr353Ile</I>, has been previously reported. These two missense variants were detected in patients with a family history of glaucoma. Combined heterozygous variants <I>p.[Thr123=;Ile288=]</I> were identified in 2 of 112 (2%) patients but not in healthy controls. Among <I>OPTN</I> variants, a novel variant <I>p.Arg271Cys</I> was identified. Homozygous <I>p.[Thr34=;Thr34=]</I> (4/112, 4%), homozygous <I>p.[Met98Lys;Met98Lys]</I> (4/112, 4%), or combined heterozygous <I>p.[Thr34=;Arg545Gln]</I> (9/112, 8%) was significantly associated with the development of primary glaucoma [odds ratio (OR)=8.768, 95% confidence interval (CI)=1.972–38.988; relative risk=1.818, 95% CI=1.473–2.244; P=0.001]. The present study provides insight into the genetic or haplotype variants of <I>MYOC</I> and <I>OPTN</I> genes contributing to primary glaucoma. Haplotype variants identified in the present study may be regarded as potential contributing factors of primary glaucoma in Korea. Further studies, including those on additional genes, are required to elucidate the underlying pathogenic mechanism using a larger cohort to provide additional statistical power.</P>
