The goal of this study was to compare two OCT-based methods for measuring retinal blood vessels size: Phase-resolved Doppler OCT (DOCT) and OCT angiography (OCTA). The study was conducted in rats (n= 6) using a SD-OCT system operating at 1060 nm with 92 kHz image acquisition rate. Arteries and veins were separated by the phase polarity. Results from this study showed that the venal diameters are significantly larger than the arterial diameters, and there is no significant difference in the vessel diameters measured by both methods.

Optical coherence tomography angiography (OCTA) was used to analyze the alterations in the density of retinal blood vessels and the choriocapillaris (VD) in patients suffering from type 2 diabetes mellitus (T2DM). One hundred sixty-six eyes of 83 patients (43 of whom were men and 40 women, with a mean age of 58.59 ± 14.04) with T2DM and without diabetic retinopathy were examined for the purpose of conducting the observational prospective study. The control group (CG) consisted of 66 eyes in 33 healthy subjects (15 male and 18 female, with a mean age of 55.12 ± 12.70). The measurement regions of vessel density (VD) included the deep capillary plexus (DCP), the superficial capillary plexus (SCP), and the choriocapillaris. The results indicate considerable differences in the VD of the DCP and SCP when comparing the control group with the study groups ( p < 0.001 ). In comparison with the control group ( p < 0.001 ), there was a statistically significant reduction in the VD of the choriocapillaris in the study group. Furthermore, patients with T2DM showed a significantly decreased VD concerning the control in different macular regions. Thickness in several macular regions in the study group significantly decreased compared to the ones in the control group. OCTA was used to gather relevant information about the vascular changes which occurred in T2DM patients, assessed through the quantitative analysis of the blood flow in the retina and choriocapillaris.
