BACKGROUND/AIMS We studied the change in choroidal thickness (CT) and axial length (AL) after intraocular (IOP) changes produced by trabeculectomy. METHODS Twenty-one eyes of 20 patients were studied preoperatively, and then postoperatively at 1 week, 1, 3, and 6 months. Variables measured included IOP, AL, keratometry, refractive error, central corneal(More)
PURPOSE To assess methods for and variations in identifying the scleral spur (SS) position in anterior segment optical coherence tomography. METHODS In images of 51 eyes (patients) with open and closed anterior chamber angles, we compared the success rate and the variability of 3 approaches for identifying the SS: the ciliary muscle (CM), bump, and(More)
IMPORTANCE With the recent development of enhanced depth imaging spectral-domain optical coherence tomography (SD-OCT), it is now possible to measure choroidal thickness in patients with Sturge-Weber syndrome and detect abnormalities that are not visible as part of the fundus examination. OBSERVATIONS We were successful in imaging at least 1 eye in 12(More)
OBJECTIVE To determine the extent of difference between better-eye visual field (VF) mean deviation (MD) and integrated VF (IVF) MD among Salisbury Eye Evaluation (SEE) subjects and a larger group of glaucoma clinic subjects and to assess how those measures relate to objective and subjective measures of ability/performance in SEE subjects. DESIGN(More)
PURPOSE To study change in choroidal thickness (CT) after water drinking test (WDT), comparing angle closure (AC) to open angle (OA) eyes. METHODS Before and 30 minutes after drinking 1 L of water, 88 glaucoma subjects underwent measurements of CT by spectral domain-optical coherence tomography, IOP, blood pressure (BP), axial length (AL), and anterior(More)
We developed a chondroitin sulfate-polyethylene glycol (CS-PEG) adhesive hydrogel with numerous potential biomedical applications. The carboxyl groups on chondroitin sulfate (CS) chains were functionalized with N-hydroxysuccinimide (NHS) to yield chondroitin sulfate succinimidyl succinate (CS-NHS). Following purification, the CS-NHS molecule can react with(More)
PURPOSE To study factors associated with choroidal thickness (CT) and to compare CT in angle closure (AC), open angle (OA), and normal eyes. METHODS Forty controls, 106 OA, and 79 AC subjects underwent measurements of posterior CT by spectral domain-optical coherence tomography, and of intraocular pressure (IOP), blood pressure, axial length (AL), and(More)
PURPOSE To assess the relationship between the pupillary light reflex (PLR) and visual field (VF) mean deviation (MD) and retinal nerve fiber layer (RNFL) thickness. METHODS A total of 148 patients with glaucoma (mean age 67 ± 11, 49% female) and 71 controls (mean age 60 ± 10, 69% female) were included in this study. Using a pupillometer, we recorded and(More)
PURPOSE Determine how procedural treatments for glaucoma have changed between 1994-2012. DESIGN Retrospective, observational analysis. PARTICIPANTS Medicare Part B beneficiaries. METHODS We analyzed Medicare fee-for-service paid claims data between 1994-2012 to determine the number of surgical/laser procedures performed for glaucoma in the Medicare(More)
PURPOSE To develop and validate an associative model using pupillography that best discriminates those with and without glaucoma. DESIGN A prospective case-control study. METHODS We enrolled 148 patients with glaucoma (mean age 67 ± 11) and 71 controls (mean age 60 ± 10) in a clinical setting. This prototype pupillometer is designed to record and(More)
