Repeatability and Reproducibility of 4.5 by 4.5 mm Peripapillary Optical Coherence Tomography Angiography Scans in Glaucoma and Non-Glaucoma Eyes.

Prcis: Peripapillary vessel parameters from optical coherence tomography angiography (OCTA) 4.5×4.5 mm scans in nonglaucomatous and glaucomatous eyes showed high repeatability and reproducibility, with higher reliability for commercially developed OCTA parameters compared with custom OCTA parameters.

Visual Field Loss Impacts Vision-Specific Quality of Life by Race and Ethnicity: The Multiethnic Ophthalmology Cohorts of California Study.

Purpose: To assess the impact of visual field loss (VFL) on vision-specific quality of life (VSQOL) by race, ethnicity, and age.

Design: Pooled analysis of cross-sectional data from 3 population-based, prospective cohort studies.

Participants: The Multiethnic Ophthalmology Cohorts of California Study (MOCCaS) participants included 6142 Latinos, 4582 Chinese Americans, and 6347 Black Americans from Los Angeles County.

Steps to Measurement Floor of an Optical Microangiography Device in Glaucoma.

Purpose: To compare dynamic ranges and steps to measurement floors of peripapillary and macular metrics from a complex signal-based optical microangiography (OMAG) optical coherence tomography angiography (OCTA) device for glaucoma with those of OCT measurements.

Design: Cross-sectional study.

Methods: Imaging of 252 eyes from 173 patients with glaucoma and 123 eyes from 92 subjects without glaucoma from a glaucoma clinic was quantified using custom and commercial software.

Impact of Visual Field Loss on Vision-Specific Quality of Life in African Americans: The African American Eye Disease Study.

Purpose: To elucidate how visual field loss (VFL) impacts self-reported vision-specific quality of life (VSQOL) in African Americans, who experience a disproportionate burden of visual impairment.

Design: Cross-sectional, population-based cohort.

Methods: Eligible participants (n = 7,957) were recruited who self-identified as African American, were aged 40 years or older, and resided in Inglewood, California, USA.

Intrasession repeatability and intersession reproducibility of peripapillary OCTA vessel parameters in non-glaucomatous and glaucomatous eyes.

Objective: To compare intrasession repeatability versus intersession reproducibility of the peripapillary vessel parameters using optical microangiography-based optical coherence tomography angiography (OCTA) in non-glaucomatous and glaucomatous eyes.

Methods: In an observational, longitudinal study, peripapillary OCTA scans were collected to evaluate intrasession repeatability and intersession reproducibility using within-eye coefficient of variation (CV) and intraclass correlation coefficient (ICC). Images were quantified using a custom research-oriented quantification software calculating vessel area density (VAD) and flux and a commercially developed, clinic-oriented quantification software (Cirrus 11.
