BACKGROUND The aim of the present study was to investigate the prevalence and characteristics of primary open-angle glaucoma among the urban population of Pudong New District, Shanghai. METHODS Three residents' committees were randomly selected from Pudong New District, and residents aged 50 and older were screened for primary open-angle glaucoma (POAG) from March to April 2011. In remote scr...

AIMS To determine the age related changes in optic nerve head structure in a group of normal subjects and assess the significance of any changes in relation to those found in open angle glaucoma. METHODS A group of 88 white volunteers and friends and spouses of patients with a normal visual field and normal intraocular pressure was studied. Two different imaging and measurement devices were u...

objective(s):glaucoma is the second leading cause of blindness and it is related to oxidative stress based on numerous studies. glutathione s-transferases (gsts) are members of multigenic family, which have important role in cells as an antioxidant. in the present study, we examined the polymorphism of gstt1 and gstm1 deletion genotypes (t0m1, t1m0, and t0m0) in 100 glaucoma patients (41with pr...

PURPOSE To investigate the test-retest variability of and factors associated with the corneal deformation response, and evaluate its impact on IOP measurement. METHODS Forty normal and 140 glaucoma suspect/glaucomatous eyes of 104 individuals were prospectively included for repeated measurements of corneal deformation response by an ultra-high-speed Scheimpflug camera, followed by corneal hys...

OBJECTIVES To compare intraocular pressure readings of recently introduced dynamic contour tonometry (DCT) with pneumatonometry (PTG) and Goldmann applanation tonometry (GAT) and to correlate central corneal thickness (CCT) with these readings. DESIGN Prospective, cross-sectional observation and instrument validation study. We included 258 independent eyes with normal anterior segment examina...

The relevance of the neuroretinal ring (NRR) for early diagnostic of glaucoma is not a novel concept. In fact, we can all remember the ISNT mnemonic rule, which represented the distribution of sector thicknessess characteristic of a healthy NRR, for discriminating between normal papilla (rule intact) and suspect or glaucomatous papillae (rule infringed). This rule was not infallible because it ...

We report our recent experience of four eyes with spontaneous lens dislocation in four patients with no history of trauma or any systemic disease associated with zonular dialysis. Lens dislocation developed with 0.5 to 6 months following laser iridotomy. All patients were male and two eyes were complicated with acute primary angle closure glaucoma preoperatively. Case 1 showed bilateral lens di...

background: glaucoma is a progressive optic neuropathy and is one of the leading causes of blindness worldwide. different factors have been contributed in the pathogenesis of glaucoma including h. pylori infection. objective: to determine the levels of anti-h. pylori igg antibody in the aqueous humor of patients with pseudoexfoliation and primary open angle glaucoma, in comparison with age and ...

OBJECTIVE To determine the causes and prevalence of ocular morbidity among primary school children in Ilorin, Nigeria. MATERIALS AND METHODS A cross sectional survey of primary school children in 10 randomly selected primary schools within Ilorin, Nigeria was carried out between July 2005 and January 2006. Relevant ocular history and basic ocular examinations were carried out on the children ...
