PURPOSE To assess whether or not the c.677C/T and c.1298A/C genetic polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) gene are associated with open angle glaucoma (OAG). METHODS Genomic DNA was examined in a cohort of 131 Japanese patients with normal tension glaucoma (NTG), 133 patients with primary open angle glaucoma (POAG), and 106 control subjects. The mean age at the time...

PURPOSE To investigate the different impacts on patient-reported vision-related quality of life (pVRQOL) outcomes in patients with primary angle-closure glaucoma(PACG) and primary open-angle glaucoma(POAG). METHODS Prospective cross-sectional study. PACG and POAG patients who had a best-corrected visual acuity(BCVA) in the better eye equal to or better than 20/60, intraocular pressure control...

Primary Open Angle Glaucoma (POAG) is a common neurodegenerative disease characterized by the selective and gradual loss of retinal ganglion cells (RGCs). Aging and increased intraocular pressure (IOP) are glaucoma risk factors; nevertheless patients deteriorate at all levels of IOP, implying other causative factors. Recent evidence presents mitochondrial oxidative phosphorylation (OXPHOS) comp...

To analyze the epidemiologic characteristics of hospitalized patients with glaucoma at Shanghai Eye and Ear, Nose, and Throat Hospital in the relative well economic condition area Eastern China.Researchers reviewed the 10 years charts of patients with a discharge diagnosis of glaucoma at this hospital from January 2004 to December 2013. With the criteria used for diagnoses of different types of...

Background: Glaucomatous neuropathy is a type of cell death by apoptosis. The p53 gene is one of the regulatory genes of apoptosis. Recently, p53 codon 72 polymorphism has been extensively studied to determine the risk factors responsible for many diseases. In the p53 gene, a single base change from G to C causes the alternation of amino acid residue 72 from arginine to proline. In this study t...

Primary open-angle glaucoma (POAG) is a primary neuronal disease of the optic nerve without a definable cause, and is often associated with increased intraocular pressure. Worldwide, POAG is the second leading cause of blindness; there are 45 million people today with POAG and bilateral blindness is present in 4.5 million of these. In order to elucidate the possible etiologic factors in POAG, w...

Untreated primary open angle glaucoma (POAG) is a blinding optic neuropathy. Timely medical or surgical treatment is eVective in slowing the rate of optic nerve damage and delaying the onset of visually disabling field loss, but treatment is only eVective in prevention, and there is as yet no means of reversing established axon loss. In the United Kingdom, around 250 000 people suVer from POAG ...

Primary open-angle glaucoma (POAG) is a highly prevalent cause of irreversible blindness which associates cupping of the optic disc and alteration of the visual field, elevation of intraocular pressure being a major risk factor. Provided diagnosis is made at an early stage, treatments are available to prevent visual impairment. A locus, GLC1A, has been mapped on chromosome 1q23-q25 in several f...

BACKGROUND To compare retinal vessel oxygenation and vessel caliber in primary angle-closure glaucoma (PACG), primary open-angle glaucoma (POAG), normal-tension glaucoma (NTG), and normal controls, as well as between eyes of asymmetrical glaucoma severity. METHODS This was a prospective, cross-sectional study. The 159 subjects (PACG, n=39; POAG, n=41; NTG, n=41; normal controls, n=38) underwe...
