Prospects Using of Colour Doppler Imaging to Study Ocular Hemodynamics in Pregnant Women with Diabetic Retinopathy. Review

Abstract

Color Doppler imaging became widespread for study hemodynamics in patients with vascular eyes pathologies. A number of studies have shown changes in ocular blood flow velocity and Doppler indices in patients with diabetes mellitus in both the absence and presence of diabetic retinopathy. With the progression of diabetic retinopathy, an increase in parameters’ changes was revealed, variations in ocular blood flow were studied after conservative treatment, retinal laser photocoagulation, against the background of anti-VEGF therapy. Due to its non-invasiveness, color Doppler imaging is used to assess orbital blood flow in pregnant patients at any gestational age. The works of this direction concern the assessment the changes in orbital blood flow during the physiological course of pregnancy and preeclampsia. However, there is still no information on the state of ocular blood flow in pregnant women with diabetes mellitus, which can serve as a basis for further research.
