BACKGROUND Genetic polymorphisms of the Optic atrophy 1 gene have been implicated in altering the risk of primary open angle glaucoma (POAG), especially the susceptibility to normal tension glaucoma (NTG), but the results remain controversial. METHODS Multiple electronic databases (up to January 20, 2012) were searched independently by two investigators. A meta-analysis was performed on the a...
PURPOSE To evaluate the association of Toll-like receptor 4 (TLR4) gene polymorphisms with normal tension glaucoma (NTG) in the South Korean population. METHODS A total of 147 normal tension glaucoma patients in South Korea were recruited from April, 2007 to August, 2008. Allele, genotype, and haplotype of 8 different types of TLR4 single nucleotide polymorphisms were analyzed: rs10759930, rs...
PURPOSE Normal tension glaucoma (NTG) is a subtype of glaucoma in which intraocular pressure is within the statistically normal range. NTG may be associated with an immune disorder. The aim of this study was to determine whether specific alleles in the human leukocyte antigen (HLA)-DRB1 and HLA-DQB1 genes correlated with NTG in Japanese patients. METHODS We genotyped the HLA-DRB1 and HLA-DQB1...
PURPOSE To compare the pattern, location, and rate of visual field (VF) change in normal-tension (NTG) and exfoliative high-tension glaucoma (XHTG). METHODS Records of all patients with glaucoma in the New York Glaucoma Progression Study with five or more VF tests were reviewed. Patients were divided into NTG (all known IOP < 21 mm Hg) and XHTG (untreated IOP >or= 21 mm Hg) groups. Automated ...
PURPOSE The expression of natriuretic peptides in the neural bundles of the anterior portion of the optic nerves and their functions in regulating vessel tone and blood flow may suggest a possible role in the pathogenesis of glaucoma. The purpose of this study was to investigate the association between normal-tension glaucoma and the genetic variations of atrial natriuretic peptide (Nppa) and n...
The velocity of blood flow in the ophthalmic artery was measured with a transcranial Doppler ultrasound (2 MHz). Sixty patients with chronic open angle glaucoma (COAG), 42 patients with normal tension glaucoma (NTG), and 35 normals were studied. Peak flow velocity (peak), mean-enveloped velocity (mean) and diastolic velocity were compared in the three groups. The COAG patients and the NTG patie...
Purpose. To assess differences in translaminar pressure gradient (TPG) and neuroretinal rim area (NRA) in patients with normal tension glaucoma (NTG), high tension glaucoma (HTG), and healthy controls. Methods. 27 patients with NTG, HTG, and healthy controls were included in the prospective pilot study (each group consisted of 9 patients). Intraocular pressure (IOP), intracranial pressure (ICP)...
PURPOSE To investigate the relationship between preferred sleeping position and asymmetric visual field (VF) loss in open-angle glaucoma (OAG) patients. DESIGN Retrospective, cross-sectional study. METHODS Six hundred and ninety-two (692) patients with bilateral normal-tension glaucoma (NTG) or high-tension glaucoma were consecutively enrolled. A questionnaire to determine the preferred sle...
PURPOSE The S1 RNA binding domain 1 (SRBD1) and elongation of long-chain fatty acids family member 5 (ELOVL5) have been reported to be susceptibility genes for early-onset normal-tension glaucoma (NTG). The present study we conducted to assess whether these genes were associated with primary open-angle glaucoma (POAG), including late-onset NTG and high-tension glaucoma (HTG). METHODS Three hu...
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...
