Figure 3From: An easy method to differentiate retinal arteries from veins by spectral domain optical coherence tomography: retrospective, observational case series Cases not applicable for grading of lower border reflectivity feature seen on spectral domain optical coherence tomography. A-C: Red arrows: Small vessels without differentiable lower border reflectivity. D-G: White arrows: Vessels with lower border right at the boundary of hyperreflective and hyporeflective retinal layers.Back to article page
