To assess the value of the provocative tests of glaucoma we investigated the water-drinking and jugular compression tests in about 140 eyes. Three groups of cases were investigated: (i) Normal eyes ... ... ... 50 (ii) Eyes with established glaucoma: (a) chronic simple glaucoma ... ... 33 (b) acute congestive glaucoma ... ... ... 13 57 (c) chronic congestive glaucoma ... ... 1 I J (iii) Pre-glau...

T he reduction of IOP remains the only course of action for primary openangle glaucoma (POAG), despite consistent observations of vascular risk factors such as low ocular perfusion pressure,1-4 vascular narrowing,5 and a higher incidence of risk factors associated with cardiovascular disease.6 As interest grows in a possible vascular role in the development of glaucoma, the number of articles o...

This study tests the hypothesis that abnormal motion displacement thresholds coexist with scotomas on a finer spatial scale than is measurable by conventional Humphrey perimetry. Eighteen patients with primary open angle glaucoma in one eye, and 18 age matched normal controls underwent motion displacement threshold testing and high spatial resolution perimetry. The motion displacement threshold...

We used background adaptation and silent substitution techniques to record full-field ON and OFF-visually evoked cortical potentials (VECPs) selectively from the S-cone and L- and M-cone pathways in 15 patients with primary open angle glaucoma (POAG), and 15 normal controls. The most statistically significant (P=0.01) VECP test for POAG was a voltage change in the S-cone pathway cortical OFF-re...

Glaucoma is the second highest cause of blindness worldwide with an estimated half of the glaucoma population unaware of their disease. To date, intraocular pressure is the most important modifiable risk factor and lowering it has been proven to reduce progression of visual field loss associated with glaucoma. Different strategies are available to lower intraocular pressure and include medical,...

Purpose To examine the factors associated with blindness from primary open-angle glaucoma (POAG) among black and white patients at our institution. Patients and methods For this retrospective, case-control study, patients legally blind from POAG ("cases") were matched on age, race, and gender with non-blind POAG patients ("controls"). Thirty-seven black case-control pairs and 19 white case-co...

AIM To present, through a thorough literature research, current and older scientific efforts to investigate the putative association between Alzheimer's disease (AD) and glaucoma, especially primary open-angle glaucoma (POAG). METHODS We included in our review article epidemiological, experimental and clinical laboratory studies. RESULTS While many authors support the existence of a strong ...

The epidemiology of eye Disease, 3rd edition, edited by Johnson GJ et al. The third edition of this authoritative text is 240 pages longer than the previous version and has 15 additional expert contributors. There is an extra chapter on research synthesis and an expanded section on visual impairment and blindness in children. Dry eye and uveitis now feature as separate entities, and the final t...

PURPOSE To assess the level of plasma glutathione in patients with untreated primary open-angle glaucoma. METHODS Twenty-one patients with newly diagnosed primary open-angle glaucoma and 34 age- and gender-matched control subjects were subjected to a blood analysis to detect the level of circulating glutathione in its reduced and oxidized forms. The effect of age, gender, and systemic blood p...

AIMS To assess the Tuck-Crick and the Quigley-Vitale predictive regression equations against fresh independent real world data for estimating the prevalence of primary open angle glaucoma (POAG) in the UK. To apply the equations to the elderly population of England and Wales, for which there is sample survey data on glaucoma, and demographic data. METHODS Directly measured actual prevalence o...
