AIM To determine (i) the prevalence of glaucoma in people aged > or =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 > or =50 years in randomly selected villages in 24 Parganas South district. The main outcome measures were dia...

This study investigated whether migraine influences the risk of primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) in Taiwan.We retrieved the data analyzed in this study from the National Health Insurance Research Database in Taiwan. We included 17,606 newly diagnosed migraine patients without preexisting glaucoma and randomly selected and matched 70,423 subjects witho...

I read the article titled “ Profile of the glaucomas and intervention in a large eye care center in South East Nepal” by Sarkar S et al (2010). The authors deserve special congratulations for presenting such a large hospital database. They have rightly pointed out that the hospital prevalence of primary angle closure glaucoma (PACG) is higher than that of the primary open angle glaucoma (POAG)....

To estimate the rate of visual field progression in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG), we reviewed the medical records of POAG and PACG patients who had a minimum of 5-year longitudinal Goldmann visual field data. I4e and I2e isopters were quantified using grid systems. The rate of change was calculated from the slope of a linear fit to a series of ave...

The records of all the glaucoma patients seen at the General Hospital Kuala Lumpur over a five year period were analysed. The racial, age and sex distribution of patients with primary open angle glaucoma and primary angle closure glaucoma was determined. The causes of secondary glaucoma were analysed. As no previous records of glaucoma statistics are available in Malaysia, it is hoped that thes...

We present the handbag contribution to Wide Angle Compton Scattering (WACS) at moderately large momentum transfer obtained with a proton distribution amplitude close to the asymptotic form. In comparison it is found to be significantly larger than results from the hard scattering (pQCD) approach.

G laucoma surgery has long relied on ab externo techniques such as augmented trabeculectomy and tube-shunt procedures. While these have excellent potential to lower intraocular pressure (IOP), they are associated with risks, including hypotony, and are therefore conventionally reserved for those with advanced glaucoma or at high risk of visual loss. Traditional filtering surgery attempts to byp...

objectives: this study sought to assess the effects of length and inclination of implants on stress distribution in an implant and terminal abutment teeth in an implant assisted-removable partial denture (rpd) using three-dimensional (3d) finite element analysis (fea).   materials and methods: in this in vitro study, a 3d finite element model of a partially dentate mandible with a distal extens...
