The Artifacts in Macular and Peripapillary OCT Angiography in Patients with Different Severities of Glaucoma.

ABSTRACT:

Purpose

To investigate the prevalence and types of artifacts in OCT angiography (OCTA) among patients with different glaucoma severities.

Design

Prospective cross-sectional study.

Subjects

Patients with open-angle glaucoma from a tertiary center were prospectively categorized into mild (mean deviation [MD] of 24-2 visual field ≥ -6 decibels [dB]), moderate (-6 to ≥ -12 dB), advanced (-12 to ≥ -20 dB), and severe glaucoma group (MD < -20 dB).

Methods

AngioVue OCTA was performed three times within a single visit to obtain superficial and deep macular vessel density (VD) with 3 x 3-mm macular scans, and peripapillary VD with 4.5 x 4.5-mm scans centered on the optic disc. The intrasession variability was assessed by the coefficient of variation (CoV). Different typ
