background: primary stability is an important factor for the clinical success of orthodontic mini-screws. the present study made an attempt to evaluate the effect of insertion angle changes on the maximum insertion and removal torque of orthodontic mini-screws. materials and methods: in this experimental study, 72 mini-screws (dual top anchor system, jeil, 1.6 mm diameter, 8 mm length) were use...

Primary angle-closure glaucoma (PACG) frequently leads to severe vision loss. Prevalence among older Asian populations is high and given global demographics, the number of persons with PACG will increase dramatically in the coming decades. Improvements in imaging of the anterior segment will help us to identify more of those with angle closure, and important clinical trials that are currently u...

Of a randomly selected sample of 40 patients with chronic simple glaucoma 11 were identified as having failed to comply adequately with medical advice. Noncompliers were more likely: to be men, to have had no other medical disorder but glaucoma, not to rank glaucoma as most troubling if they had another illness, to have experienced side effects from the treatment, and not to have appreciated th...

materials and methods: one hundred and thirty five mesial root canals of mandibular first and second molar teeth were selected. access cavities were prepared. after inserting a k-file size #10 into each canal, radiographs were taken. canal curvature was determined by measuring the schneider angle, canal access angle, as well as the canal radius, length, height and curvature starting distance on...

PURPOSE Glaucoma prevalence can vary geographically and ethnically, which suggests that a genetic element could play a significant role. Studies investigating the role of various mitochondrial haplogroups in the pathogenesis of glaucoma are scarce. METHODS We compared the prevalence of different mitochondrial haplogroups in 107 glaucoma patients (49 primary open-angle glaucoma, POAG; 29 prima...

PURPOSE To determine the incidence and contribution of different types of glaucoma to blindness at Irrua Specialist Teaching Hospital, a suburban tertiary care hospital in Edo State, Nigeria. METHODS Medical records of all new patients with glaucoma who presented to the eye clinic of the hospital from June 2007 to May 2009 were reviewed. RESULTS Out of a total of 2,742 new patients seen ove...

PURPOSE To evaluate in different types of glaucoma frequency of family history of glaucoma (FHG), age at diagnosis, glaucoma risk in relatives, and acceptance rate of genetic glaucoma tests. To assess stage of visual field loss (VFL) in relation to FHG. METHODS Using standardized questions whether an ophthalmologist had found or excluded glaucoma or ocular hypertension (OH), 2170 patients wit...

OBJECTIVE To map new genetic loci for adult-onset primary open-angle glaucoma (POAG) by using families previously unlinked to GLC1A-GLC1F. METHODS Initial genome scan and subsequent saturation mapping confirmed linkage to a locus on chromosome 2p15-p16. Forty-nine DNA samples from a single family with POAG with 113 individuals were used in this study. The 10 affected members of this family ha...

Background Glaucoma, the second leading cause of blindness, affects approximately 64.3 million individuals worldwide. In China, demographic ageing is in rapid progress. Yet detailed and up-to-date estimates of the scale of glaucoma are rare. We aimed to quantify and understand the prevalence and burden of glaucoma in China from 1990 to 2015, with projections until 2050. Methods For this syste...
