Srinivas S, et al. - Doppler Fourier-domain optical coherence tomography (FD-OCT) was used to assess retinal blood flow measurements in normal eyes and eyes with varying levels of diabetic retinopathy (DR). Findings revealed that compared with normal eyes, total retinal blood flow was significantly lower in eyes with severe nonproliferative DR (NPDR) and proliferative DR (PDR). Data suggested that for assessing patients with DR, retinal blood flow determined by Doppler OCT may be a useful parameter.
