| Summary: | Background. Recently, more and more attention has been paid to the development of vascular retinal disorders after suffering preeclampsia. It is noted that the key role in this process is assigned to the systemic endothelial dysfunction that persists for a long time after delivery.Aim: to elucidate the features of vascular-platelet and coagulation hemostasis in relation to the indicators of blood flow in the macular region in women with preeclampsia.Materials and methods. The main group included 45 women with preeclampsia in the third trimester of pregnancy (35–36 weeks). Their age ranged from 19 to 40 years (27 ± 5.2 years). The comparison group was represented by 20 women with physiological pregnancy in the third trimester (35–36 weeks). Their age averaged 26 ± 5.1 years (18–38 years). Somatically healthy non-pregnant women (20 people) were included in the control group. Their age ranged from 19 to 38 years (26 ± 5.4 years). A comparative analysis of the studied parameters of macular blood fl ow, vascular-platelet and coagulation hemostasis between the groups was carried out.Results. When studying the number of platelets in pregnant women, it turned out that in patients with preeclampsia, this indicator was statistically signifi cantly lower compared to the comparison and control groups (p < 0.05). The level of fi brinogen in women with complicated pregnancies was statistically significantly higher than in women with physiological pregnancy and in somatically healthy nonpregnant women (p < 0.05). In addition, retinal microcirculation disorders were observed in women of the main group.Conclusions. The revealed disorders of vascular-platelet and coagulation hemostasis in women during the period of complicated pregnancy were accompanied by disorders of macular blood fl ow in the form of a decrease in the total average density of vessels in the superfi cial vascular plexus, subfoveolar thickness of the choroid and an increase in the area of the avascular zone relative to the group of women with physiological pregnancy and somatically healthy nonpregnant women. |
