PURPOSE: To evaluate the sectoral and global structure-structure (vessel density-retinal nerve fiber layer thickness) and structure-function (vessel density-visual sensitivity loss) relationships of peripapillary vessel density measurements on optical coherence tomography angiography in primary open-angle glaucoma and to determine if fractional polynomial (FP) models characterize the relationships better than linear models. MATERIALS AND METHODS: In a cross-sectional study, structure-structure and structure-function relationships of peripapillary vessel densities were determined in 227 eyes of 143 subjects (63 control and 164 primary open-angle glaucoma eyes) who had undergone standard automated perimetry and optical coherence tomography testing within 6 months of each other, using linear and FP models...

PURPOSE: For patients with comorbid cataract and primary open-angle glaucoma (POAG), guidance is lacking as to whether cataract extraction and traditional filtering surgery should be performed as a staged or combined procedure. Achieving this guidance requires an evidence-based understanding of the effects of phacoemulsification alone on intraocular pressure (IOP) in patients with POAG. For this reason, a systematic review and meta-analysis was undertaken to synthesize evidence quantifying the effect of phacoemulsification on IOP and the required number of topical glaucoma medications in patients with cataract and POAG...

PURPOSE: To assess the accuracy of crowdsourcing for grading optic nerve images for glaucoma using Amazon Mechanical Turk before and after training modules. MATERIALS AND METHODS: Images (n=60) from 2 large population studies were graded for glaucoma status and vertical cup-to-disc ratio (VCDR). In the baseline trial, users on Amazon Mechanical Turk (Turkers) graded fundus photos for glaucoma and VCDR after reviewing annotated example images. In 2 additional trials, Turkers viewed a 26-slide PowerPoint training or a 10-minute video training and passed a quiz before being permitted to grade the same 60 images...

PURPOSE: To determine whether the change in the retinal nerve fiber layer (RNFL) thickness in a region of interest (ROI) is a better measure of glaucoma progression than the change in average circumpapillary (cp) RNFL thickness. METHODS: Disc cube scans were obtained with frequency domain optical coherence tomography from 60 eyes of 60 patients (age, 61.7±12.7 y) with early or suspected glaucoma and controlled intraocular pressure. The average time between 2 test dates was 3...

PURPOSE: To demonstrate the utility of swept-source anterior segment optical coherence tomography (SS-AS-OCT) in guiding placement of transconjunctival sutures in hypotonous patients after a trabeculectomy. PATIENTS AND METHODS: This is a longitudinal case series of 10 eyes from 10 patients who required transconjunctival sutures after a trabeculectomy. SS-AS-OCT was used to aid in the placement of the sutures to improve the function of the overfiltering bleb. RESULTS: SS-AS-OCT reliably identified localized areas of overfiltering, allowing for targeted suture placement in 8 eyes...

Phacolytic glaucoma is an open-angle glaucoma that occurs when lens proteins from hypermature cataracts seep through an intact anterior capsule and induce obstruction of the trabecular meshwork by inflammatory cells. We review the case of a 66-year-old man who presented with acute pain, a hypermature cataract, prominent anterior chamber crystals, and elevated intraocular pressure. After cataract surgery was performed, iridescent crystals were noted in the posterior chamber. Anterior chamber crystals have been associated with phacolytic glaucoma, but this is the first case demonstrating crystals in the posterior chamber as well...
