Analysis of Foveal Microvascular Abnormalities in Diabetic Retinopathy Using Optical Coherence Tomography Angiography with Projection Artifact Removal

Figure 1

Measurement of optical coherence tomography angiography parameters on a 3 × 3 mm². (a) The measurement of foveal retinal thickness. (b) The measurement of the foveal avascular zone. The following parameters were evaluated: area, perimeter, acircularity index, and vessel density of FD-300. (c, e) the vessel density in the superficial and deep capillary plexus. (d, f) Color maps show the vessel density in the superficial and deep capillary plexus.
