Projection-Resolved Optical Coherence Tomography Angiography of Macular Retinal Circulation in Glaucoma.

ABSTRACT:

Purpose

To detect macular perfusion defects in glaucoma using projection-resolved optical coherence tomography (OCT) angiography.

Design

Prospective observation study.

Participants

A total of 30 perimetric glaucoma and 30 age-matched normal participants were included.

Methods

One eye of each participant was imaged using 6×6-mm macular OCT angiography (OCTA) scan pattern by 70-kHz 840-nm spectral-domain OCT. Flow signal was calculated by the split-spectrum amplitude-decorrelation angiography algorithm. A projection-resolved OCTA (PR-OCTA) algorithm was used to remove flow projection artifacts. Four en face OCTA slabs were analyzed: the superficial vascular complex (SVC), intermediate capillary plexus (ICP), deep capillary plexus (DCP), and all-plexus retina (SVC
