Primary open angle glaucoma (POAG) is a one of the most common eye diseases in the world, especially in China. Many inflammatory markers are likely to be closely related to the development of POAG, especially cytokines. The aim of our investigation is to reveal the potential association of three interleukin-6 (IL-6) gene SNPs on primary open-angle glaucoma risk factors in Chinese. A case-contro...

PURPOSE The present study was designed to determine the association of polymorphisms of the DNA repair genes X-ray cross-complementing group 1 (XRCC1) (c.1316G>A [rs25487]) and xeroderma pigmentosum complementation group D (XPD) (c.2298A>C [rs13181]) with primary open-angle glaucoma (POAG) and primary closed-angle glaucoma (PCAG). METHODS In this prospective case-control study, polymerase cha...

PURPOSE Myocilin gene defects have been originally implicated in primary open angle glaucoma (POAG). Based on multiple reports for the occurrence of Gln48His mutation (c.144G>T; HGMD accession number CM023962) among Indian POAG patients, we wanted to estimate the prevalence of this mutation in primary open angle and primary congenital glaucoma (PCG) in India and assess its role in the causation...

PURPOSE The optineurin gene (OPTN) is the second gene besides MYOC in which mutations have been identified to be associated with primary open-angle glaucoma (POAG). In this study, sequence alterations in the OPTN gene associated with POAG in Chinese subjects were investigated. METHODS All the coding exons of OPTN were screened, including the intron-exon boundaries, for sequence alterations in...

Temporal sensitivity was assessed in patients with primary open-angle glaucoma (POAG) and ocular hypertension (OHT). Three measures of flicker sensitivity were obtained: psychophysical modulation thresholds, visual-evoked potentials (VEPs), and focal electroretinograms (FERGs). We found elevated psychophysical thresholds at higher temporal frequencies (30-50 Hz) in patients with POAG, relative ...

PURPOSE To investigate the safety and efficacy of selective laser trabeculoplasty (SLT) to reduce intraocular pressure (IOP) in patients with pseudoexfoliation glaucoma (PXFG) compared with primary open-angle glaucoma (POAG). DESIGN Non-randomized, prospective, clinical trial. METHODS Nineteen eyes of 13 patients with POAG and 18 eyes of 13 patients with PXFG were treated with SLT. Patients...

OBJECTIVE To test the hypothesis that genetic polymorphisms of the apolipoprotein E (APOE) gene are associated with primary open-angle glaucoma (POAG), based on the association between neurodegenerative diseases and the APOE genotype. METHODS Genomic DNA was examined from an unrelated cohort of 137 POAG patients and 75 control subjects from the ophthalmology department of the Royal Victoria I...

BACKGROUND The association of the WDR36 gene with glaucoma has been controversial in the literature. We therefore conducted a systematic review and meta-analysis to assess the association of all reported common polymorphisms in WDR36 with primary open angle glaucoma (POAG) and its subtypes: high tension glaucoma (HTG) and normal tension glaucoma (NTG). METHODS Publications in PUBMED and EMBAS...

OBJECTIVES To investigate the prevalence of myocilin (MYOC) mutations in Italian families with glaucoma and to determine the relationship of these mutations to primary open-angle glaucoma (POAG), juvenile open-angle glaucoma (JOAG), and pigmentary dispersion glaucoma. METHODS Twenty-six patients with POAG were selected based on a positive family history of glaucoma. All patients and 210 relat...

IMPORTANCE Nitric oxide signaling alterations in outflow facility and retinal blood flow autoregulation are implicated in primary open-angle glaucoma (POAG). Nitric oxide donation has emerged as a POAG therapeutic target. An exogenous source of nitric oxide is dietary nitrates. OBJECTIVE To evaluate the association between dietary nitrate intake, derived mainly from green leafy vegetables, an...
