purpose. To delineate three-dimensionally the anterior and posterior surfaces of lamina cribrosa, scleral flange, peripapillary sclera, to determine position thickness these structures within digital three-dimensional (3-D) reconstructions monkey optic nerve head (ONH). methods. The trephinated ONH sclera from both eyes three monkeys with early glaucoma (EG; one eye normal, given laser-induced EG) were serially sectioned at 3-μm thickness, embedded tissue block's face stained imaged after...
<h3>Objective</h3> To assess visibility of the scleral spur in anterior segment optical coherence tomography (AS-OCT) images. <h3>Methods</h3> This cross-sectional observational study included 502 participants aged 50 years or older who had no previous ophthalmic problems and were recruited from a community clinic Singapore. All underwent gonioscopy AS-OCT (Visante; Carl Zeiss Meditec, Dublin, California). Scleral location was assessed images by 2 examiners with glaucoma subspecialty...
<h3>Aim:</h3> To describe a new image analysis method and software for anterior chamber images obtained by the anterior-segment optical coherence tomography (AS-OCT) to assess its intraobserver interobserver measurement reproducibility. <h3>Methods:</h3> Twenty 8-bit greyscale 600×300 AS-OCT with apparent wide angles 20 narrow were consecutively selected from database. Two glaucoma fellowship-trained ophthalmologists used proprietary analyse twice. Algorithms defined borders curvatures of...
To delineate three dimensionally the neural canal landmarks-Bruch's membrane opening (BMO), anterior sclera (ASCO), laminar insertion (ALI), posterior (PLI), and scleral (PSCO)-and anterior-most aspect of subarachnoid space (ASAS), within digital three-dimensional (3-D) reconstructions monkey optic nerve head (ONH).The trephinated ONH peripapillary from both eyes early glaucoma (EG) monkeys (one eye normal, one with laser-induced EG) were serial sectioned at 3-microm thickness, embedded...
To assess the diagnostic performance of angle measurements from anterior segment optical coherence tomography (AS-OCT) images for identifying eyes with narrow angles.We conducted a community-based cross-sectional study individuals 50 years or older who had phakic and underwent AS-OCT imaging in dark by single operator gonioscopy an ophthalmologist masked to findings. An eye was considered have angles if posterior pigmented trabecular meshwork not visible at least 180° on gonioscopy....
To assess the prevalence of glaucoma in a South Brazilian population.Subjects older than 40 years underwent screening examination that included medical interview, slit lamp examination, tonometry, and fundoscopy. Those with suspected (based on optic disc appearance and/or intraocular pressure) comprehensive ophthalmic evaluation during definitive examination. Glaucoma was diagnosed based International Society Geographical Epidemiologic Ophthalmology classification.A total 1636 subjects were...
HOW BIG IS THE PROBLEM?A recent estimate of the number people affected by glaucoma worldwide suggested that 2020 there will be approximately 80 million with disease, which 11 bilaterally blind (1) .Due to paucity information on disease prevalence in Latin America, estimates for this region have been derived mostly from studies conducted Hispanic populations living United States .These extrapolated rates are likely inaccurate, particularly Brazil, due its heterogeneous and highly...
<h3>Objectives</h3> To describe the measurement of anterior chamber area and volume by anterior-segment optical coherence tomography to investigate association these parameters with presence narrow angles. <h3>Methods</h3> This was a cross-sectional study subjects aged at least 50 years without ophthalmic symptoms recruited from community clinic. All participants underwent standardized ocular examination tomography. Customized software used measure (cross-sectional bounded corneal...
To determine and compare the effect of severity glaucomatous damage on repeatability retinal nerve fiber layer (RNFL) thickness with GDx-VCC (variable corneal compensation) StratusOCT (optical coherence tomography; both produced by Carl Zeiss Meditec, Inc., Dublin, CA), optic head (ONH) topography HRT-II (retinal tomograph; Heidelberg Engineering GmbH, Heidelberg, Germany) StratusOCT.With each these techniques, two measurements were obtained from 41 eyes control subjects 98 (37 patients...
Baseline anterior segment imaging parameters associated with incident gonioscopic angle closure, to our knowledge, are unknown.To identify baseline quantitative optical coherence tomography the development of closure after 4 years among participants gonioscopically open angles at baseline.Three hundred forty-two aged 50 or older were recruited participate in this prospective, community-based observational study. Participants underwent gonioscopy and years. Custom image analysis software was...
To assess the relationship between intraocular pressure (IOP) and anterior chamber angle (ACA) configuration as assessed by gonioscopy segment optical coherence tomography (AS-OCT).A total of 2045 subjects aged 50 years older, were recruited from a community clinic underwent AS-OCT, Goldmann applanation tonometry, gonioscopy. A quadrant was classified closed on if posterior trabecular meshwork could not be seen. AS-OCT defined presence any contact iris wall to scleral spur. Customized...
