Invest Ophthalmol Vis Sci. 2013. Abstract: PURPOSE: To assess the relationship between intraocular pressure (IOP) and anterior chamber angle (ACA) configuration as assessed by gonioscopy and anterior segment optical coherence tomography (AS-OCT). METHODS: A total of 2045 subjects aged 50 years and older, were recruited from a community clinic and underwent AS-OCT, Goldmann applanation tonometry, […]

Ophthalmology. 2013. Abstract: OBJECTIVE: A recent study found that a combination of 6 anterior segment optical coherence tomography (ASOCT) parameters (anterior chamber area, volume, and width [ACA, ACV, ACW], lens vault [LV], iris thickness at 750 μm from the scleral spur, and iris cross-sectional area) explain >80% of the variability in angle width. The aim […]

Am J Ophthalmol. 2012. Abstract: PURPOSE: To describe the distribution and determinants of lens vault and to investigate the association of lens vault with narrow angles. DESIGN: Prospective cross-sectional study. METHODS: Phakic subjects 50 years and older were evaluated at a primary healthcare clinic with gonioscopy, partial laser interferometry, and anterior segment optical coherence tomography […]

Invest Ophthalmol Vis Sci. 2007. Abstract: METHODS: Subjects older than 40 years underwent a screening examination that included a medical interview, slit lamp examination, tonometry, and fundoscopy. Those with suspected glaucoma (based on optic disc appearance and/or intraocular pressure) underwent a comprehensive ophthalmic evaluation during the definitive examination. Glaucoma was diagnosed based on the International […]

J Glaucoma. 2006. Abstract: PURPOSE: Nonpupil block mechanisms and appositional angle closure after laser iridotomy (LI) have been reported as common findings in Asians. We evaluated the presence of these findings in a cohort of Brazilian patients using ultrasound biomicroscopy (UBM). METHODS: This observational case-control study included 22 open angle eyes and 31 eyes with […]
