PURPOSE To determine the prevalence of primary open-angle glaucoma (POAG) in Segovia, Spain. METHODS We conducted a cross-sectional, population-based epidemiologic study, the target population of which was residents of Segovia, Spain, aged 40 to 79 years. A sample of 569 subjects was randomly selected in a stratified manner according to gender and age(More)
PURPOSE To determine the diagnostic accuracy of judging optic disc photographs for glaucoma by ophthalmologists. DESIGN Evaluation of diagnostic test and technology. PARTICIPANTS A total of 243 of 875 invited ophthalmologists in 11 European countries. METHODS We determined how well each participant classified 40 healthy eyes and 48 glaucomatous eyes(More)
PURPOSE To evaluate safety and clinical outcomes of a novel supraciliary device, the CyPass Micro-Stent, for surgical treatment of open-angle glaucoma when implanted in conjunction with cataract surgery. PATIENTS AND METHODS Subjects (n=142) with open-angle glaucoma and cataract underwent combined phacoemulsification, with intraocular lens insertion, and(More)
PURPOSE To evaluate the relation between the location of focal visual field defects and optic disk damage in eyes with glaucoma by short-wavelength automated perimetery and confocal scanning laser ophthalmoscopy. METHODS In 14 patients (14 eyes) with open-angle glaucoma, focal optic disk damage, and focal visual field loss, we obtain visual fields with(More)
PURPOSE To develop a quantitative method for analysis of the topographic relationship between structural and functional damage in patients with glaucoma. METHODS We studied 26 patients with primary open-angle glaucoma, focal optic disk damage, and focal visual field loss. The visual field was evaluated with automated perimetry, and the optic disk(More)
OBJECTIVE To measure and compare scanning laser polarimeter measurements of the nerve fiber layer in normal subjects and in patients with ocular hypertension (OHT). METHODS Scanning laser polarimetry was performed in 39 normal subjects and 39 age-matched patients with OHT. One eye of each patient was randomly selected for the study. For each eye, a mean(More)
PURPOSE To assess sensitivity, specificity, and agreement among automated event analysis, automated trend analysis, and expert evaluation to detect glaucoma progression. METHODS This was a prospective study that included 37 eyes with a follow-up of 36 months. All had glaucomatous disks and fields and performed reliable visual fields every 6 months. Each(More)
PURPOSE To study the patterns of structural damage of the optic disk in patients with early focal visual field loss using a confocal scanning laser ophthalmoscope. METHODS Thirty-nine subjects with repeatable early focal visual field loss were included. The Heidelberg Retina Tomograph (Heidelberg Engineering, Heidelberg, Germany) was used to obtain(More)
PURPOSE To assess Stratus optical coherence tomography (OCT) original parameters for identifying glaucomatous damage and to evaluate differences among glaucomatous, ocular hypertensive, and normal eyes. DESIGN Cross-sectional prospective study. SUBJECTS AND METHODS The study was conducted at 2 centers. The study population consisted of 55 normal(More)
PURPOSE To determine the prevalence of refractive errors in Segovia, Spain. METHODS A cohort of 569 subjects was randomly selected in a stratified manner according to gender and age in a cross-sectional, population-based epidemiologic study, the target population of which was urban residents aged 40 to 79 years. All participants underwent an ophthalmic(More)
