Repeatability, reproducibility and agreement of foveal avascular zone measurements using three different optical coherence tomography angiography devices.

ABSTRACT:

Purpose

To evaluate the repeatability, the reproducibility and the agreement of foveal avascular zone (FAZ) measurements using three different optical coherence tomography angiography (OCT-A) devices.

Procedures

This prospective study included 24 eyes of 24 healthy volunteers. OCT-A imaging was performed using RTVue XR Avanti, Canon OCT-HS100 and Spectralis OCT-A. Repeated measurements were performed under the same conditions on two separate days, and the area of the FAZ was determined and analyzed using the above devices.

Results

All three devices showed a high ICC and there was no significant difference between the ICCs (pairwise comparison) of the three devices (Optovue-Canon (p = 0.66); Canon-Heidelberg (p = 0.21); Heidelberg-Optovue (p = 0.37). Agreement analysis
