Using three-dimensional OCTA metrics improves repeatability on quantification of ischemia in eyes with diabetic macular edema

Purpose: Two-dimensional (2D) optical coherence tomography angiography (OCTA) is known to be prone to segmentation errors, especially in pathologic eyes. Therefore, our aim was to systematically compare intra-session repeatability between repeated scans for 2D and three-dimensional (3D) OCTA metrics in quantifying retinal perfusion in eyes with diabetic macular edema (DME). Methods: Diabetic patients with diabetic retinopathy (DR) and DME who had two consecutive OCTA imaging scans obtained during the same ...
