purpose : there are controversial reports regarding the long-term intraocular pressure (iop) lowering effect of non-penetrating glaucoma surgery (npgs). the reported complete success rates from studies in different populations around the world are 13% to 77%. this prospective study was aimed to evaluate the iop lowering effect of deep sclerectomy with mitomycin c (dsmmc) in a group of iranian p...
Pharmacogenomics is an evolving research discipline in medicine. Within ophthalmology, the earliest candidate gene investigations have studied primary and secondary open-angle glaucoma (OAG), as well as normal tension glaucoma (NTG). At this time, pharmacogenomics data are not generally used to make clinical decisions. However, as we collect data from clinical trials, the role of pharmacogenomi...
purpose : to compare the intraocular pressure (iop) lowering effect and side effects of xalatan with generic latanoprost (xalabiost) in adults with open-angle glaucoma or ocular hypertension methods : this was a two-center prospective randomized, crossover clinical trial. eligible patients with open-angle glaucoma or ocular hypertension were sequentially randomized to two parallel study groups ...
BACKGROUND The purpose of this study was to determine outcomes when using Trabectome surgery and to evaluate factors associated with its effects in primary open-angle glaucoma (POAG) and exfoliation glaucoma (EXG). METHODS This was a prospective, non-randomized, observational, comparative cohort study in which Trabectome surgery was used alone in patients with POAG or EXG. Trabectome surgery ...
PURPOSE To investigate in parallel the systemic glutathione levels of patients suffering from primary open angle glaucoma (POAG) or normal tension glaucoma (NTG) with comparable functional loss. METHODS Thirty-four POAG patients, 30 NTG patients, and 53 controls were subjected to blood analysis to detect the level of circulating glutathione in its reduced (GSH) and oxidized (GSSG) forms. Syst...
Purpose: We compared visual field progression among patients with primary open-angle glaucoma (POAG), normal tension (NTG), and angle-closure (PACG).Methods: A total of 115 POAG, 123 NTG, 92 PACG eyes were retrospectively analyzed. Global VF was evaluated by calculating the changes mean deviations. To examine local deterioration, scotoma enlargement deepening analyzed in superior, inferior arcu...
Malignant glaucoma is a rare form of glaucoma that typically follows surgery in patients with primary angle closure and primary angle-closure glaucoma. In this paper, the clinical features, classification, pathogenesis, and principles of management are discussed. Despite a high prevalence of primary angle closure glaucoma in South-East Asia, the vast majority of cases of malignant glaucoma are ...
A glaucoma locus, GLC1A, was identified previously on chromosome 1q. A gene within this locus (encoding the protein myocilin) subsequently was shown to harbor mutations in 2-4% of primary open angle glaucoma patients. A total of 1703 patients was screened from five different populations representing three racial groups. There were 1284 patients from primarily Caucasian populations in Iowa (727)...
PURPOSE To assess the prevalence and mechanism of glaucoma in adults living in an urban area of southern China. METHODS Random clustering sampling was used to identify adults aged 50 years and over in Liwan District, Guangzhou. Glaucoma was diagnosed with the ISGEO (International Society of Geographical and Epidemiological Ophthalmology) classification scheme. All subjects underwent gonioscop...
OBJECTIVE To investigate the association between Primary Open Angle Glaucoma (POAG), Intraocular Pressure (IOP) and systemic hypertension. DESIGN Cross-sectional, convenient and controlled study. SETTING Eye Clinic of the Lagos University Teaching hospital, Idi-Araba, Lagos, Nigeria. SUBJECTS Consecutive newpatients with documented history of hypertension medication of over three months a...
