OCT-angiography: A qualitative and quantitative comparison of 4 OCT-A devices.

ABSTRACT:

Purpose

To compare the quality of four OCT-angiography(OCT-A) modules.

Method

The retina of nineteen healthy volunteers were scanned with four OCT-devices (Topcon DRI-OCT Triton Swept-source OCT, Optovue RTVue-XR, a prototype Spectralis OCT2, Heidelberg-Engineering and Zeiss Cirrus 5000-HD-OCT). The device-software generated en-face OCT-A images of the superficial (SCP) and deep capillary plexuses (DCP) were evaluated and scored by 3 independent retinal imaging experts. The SCP vessel density was assessed using Angiotool-software. After the inter-grader reliability assessment, a consensus grading was performed and the modules were ranked based on their scoring.

Results

There was no significant difference in the vessel density among the modules (Zeiss 48.7±4%, Optovue
