    Quantitative Comparison Of Microvascular Metrics On Three Optical Coherence Tomography Angiography Devices In Chorioretinal Disease

    Purpose: Optical coherence tomography angiography (OCT-A) has emerged as a novel tool for the non-invasive imaging and evaluation of the retinal microvasculature. There is little existing literature that compares OCT-A microvasculature metrics across different OCT-A devices in chorioretinal diseases. Herein, we examined these metrics on three available OCT-A platforms. Patients and methods: All subjects were scanned on each of three OCT-A devices: Optovue Avanti Angiovue, Topcon DRI-OCT Triton Swept-Source OCT, and Zeiss Cirrus 5000-HD-OCT Angioplex. Two investigators independently measured foveal avascular zone (FAZ) area. Superficial capillary plexus (SCP) and deep capillary plexus (DCP) vessel densities (VD) were calculated from binarized ...
