Conclusion: There were increases in RVOD, RVLD, VWT, and VWCSA, decrease in AVR in patients with GDM. However, no significant difference of retinal vascular parameters was shown between normal pregnant women and normal non pregnant women.
There were statistically significant differences in the retinal venous diameter and arterial vein ratio in the GDM and DM2 groups compared to the control group (P = 0.001 for all). Conclusion: The microvascular density changes seen on OCTA images of pregnant women with GDM are remarkable.
This review discusses the use of optical coherence tomography angiography (OCTA) as a diagnostic tool for the early detection and management of DR. OCTA is a fast, non invasive, non contact test that enables the detailed visualisation of the macular microvasculature in different plexuses.
In this study, we introduced a novel volumetric method to identify arteriolar and venular connected capillaries from three dimensional (3D) OCTA slabs, which we use to characterize arteriovenous differences in healthy eyes.
In this article, we provide a brief summary of technical rationales and clinical applications of differential AV analysis in fundus photography, optical coherence tomography (OCT), and OCT angiography (OCTA).
However, clinical optical coherence tomography angiography (OCTA) instruments lack the function of artery vein differentiation. This study aims to verify the feasibility of using OCT intensity feature analysis to guide artery vein differentiation in OCTA.
The microvascular density changes seen on OCTA images of pregnant women with GDM are remarkable. These changes in retinal vessels appeared to occur rapidly after the onset of the metabolic impairment or might be the reflection of previous insulin resistance as well, as in recent diabetes.
PKSEA Net can assist to identify changes in retinal vascular morphology and diagnose micro vascular lesion early in normal pregnant women and high risk groups of GDM.
We evaluated the diferent methods used to assess retinal perfusion between OCTA studies. MEDLINE and Embase were searched from 2014 to August 2021. We included prospective studies including ≥ 50...
Heidelberg engineering® uses the active eye tracking system (TruTrack™) that assesses simultaneously fundus and OCT images acquisition in order to achieve a better signal to noise ratio.
