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...

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...

Static automated visual field testing is now an integral part of the detection and monitoring of primary open angle glaucoma. However, although many aspects of testing are automated, interpretation of the large amounts of data produced by these instruments is not. Two major challenges facing the practitioner are differentiating between the visual fields of a patient with early glaucoma and thos...

The change in intraocular pressure achieved after 98 trabeculectomy operations performed on 70 patients with primary open-angle glaucoma was analysed. The reduction was proportional to the untreated preoperative pressure, and the results indicated that a first trabeculectomy reduced the intraocular pressure to between 16 and 20 mmHg irrespective of its initial level. Cases which required medica...

The purpose of this study was to determine the association of well-being and cognitive impairment with primary open angle glaucoma (POAG) patients attending a tertiary care hospital in Malaysia. Fifty-four individuals were recruited for study as cases were matched with 60 individuals as the control subjects, and data were collected using the WHO well-being index and the validated 6-item cogniti...

PURPOSE To determine if open-angle glaucoma (OAG)-associated single nucleotide polymorphisms (SNPs) are associated with incident glaucoma and if such genetic information is useful in OAG risk prediction. DESIGN Case-control from within a population-based longitudinal study. METHODS study population: Individuals aged over 49 years of age living in the Blue Mountains region west of Sydney and...

Refractive errors and primary open-angle glaucoma are common eye conditions in the United States. The identification and quantification of risk factors for primary open-angle glaucoma is critical to understanding and managing the disease process from both individual and public health perspectives. This narrative review was conducted to present the epidemiology of primary open-angle glaucoma and...

OBJECTIVE The aim of this study was to determine the prevalence of open angle glaucoma in first-degree relatives accompanying POAG patients during routine examination in a reference hospital. METHOD First-degree relatives of primary open angle glaucoma patients who accompanied their relatives to the glaucoma service of a reference hospital were screened for glaucoma. RESULTS One-hundred and...

The CYP1A1 gene is related to the generation of secondary metabolites that are capable of inducing DNA damage. The CYP1A1m1 polymorphism has been examined in many studies, and is located in a region near loci that have been linked to glaucoma, including the locus GLC1I. As a result, this polymorphism has been related to several diseases that are influenced by exposure to xenobiotic as well as p...
