Acute angle closure glaucoma is an ophthalmic emergency and can lead to blindness if left untreated. Several types of drugs have the potential to precipitate acute angle closure glaucoma. These include adrenergic, cholinergic and anticholinergic, antidepressants, anticoagulants and sulfa-based agents. This article provides a basic overview of the risk factors and pathophysiologic mechanisms inv...

INTRODUCTION Primary angle-closure glaucoma (PACG) is a major cause of blindness among Asians. A better understanding of the disease will improve the treatment and outcome of this condition. METHODS A literature review of all recent publications on PACG was carried out. Articles were retrieved using a key word search of MEDLINE, PubMed and Science Citation Index databases. RESULTS Following...

Shorter axial length observed in patients with primary angle closure glaucoma (PACG) might be due to altered matrix metalloproteinase-9 (MMP9) activity resulting in ECM remodeling during eye growth and development. This study aimed to evaluate common variants in MMP9 for association with PACG. Six tag SNPs of MMP9 were genotyped in a Chinese sample of 1,030 cases, including 572 PACG and 458 pri...

BACKGROUND The purpose of this study was to investigate the association of a novel biometric parameter, relative lens vault (LV), with primary angle-closure (PAC) and primary angle-closure glaucoma (PACG). METHODS We evaluated 101 subjects with PAC (G) and 101 normal subjects that were age- and gender-matched. Based on anterior-segment optical coherence tomography scans, and using customized ...

Aim: To determine (i) the prevalence of glaucoma in people aged >50 years, (ii) the proportions of different types of glaucoma, (iii) the distributions of intraocular pressure and vertical cup disc ratio. Method: Population based prevalence survey in rural West Bengal. People aged >50 years in randomly selected villages in 24 Parganas South district. The main outcome measures were diagnosis of ...

PURPOSE To document the diurnal intraocular pressure (IOP) profile with rebound tonometry performed by primary glaucoma patients in non-clinic environment. PATIENTS AND METHODS Fifty-three medically-treated eyes of 31 primary angle closure glaucoma (PACG) and 22 primary open angle glaucoma (POAG) patients with no previous eye surgery were recruited. Diurnal IOP was measured 5 times per day at...

Radiation has been associated with increases in noncancerous diseases. An effect of low-dose radiation on the prevalence of clinically detected glaucoma has not been previously reported. We therefore investigated the prevalence of glaucoma in A-bomb survivors and its possible association with radiation dose. A total of 1,589 people who participated in the clinical examination program for A-bomb...

PURPOSE Mouse serine protease 56 (Prss56) mutants show a phenotype of angle-closure glaucoma with a shortened ocular axial length. Mutations in the human PRSS56 gene are associated with posterior microphthalmia and nanopthalmos. In this study, variations in PRSS56 were evaluated in patients with either primary angle-closure glaucoma (PACG) or high hyperopia. METHODS A total of 561 participant...

Primary angle-closure glaucoma is a major cause of blindness worldwide. It is a disease of ocular anatomy that is related to pupillary-block and angle-crowding mechanisms of filtration angle closure. Eyes at increased risk for primary angle-closure are small with decreased axial length, anterior chamber depth, and filtration angle width, associated with a proportionately large lens. Angle-closu...
