The choroidal blood flow of eye during pregnancy and in postnatal period in women with preeclampsia, clinical part for predicting risk of vascular pathology of posterior segment of the eye
Methods: The main group: 42 pregnant women with PE. The 1st experimental group: 30 women with physiological gestation course. The 2nd experimental group: 27 non-pregnant women with vascular pathology of posterior segment of the eye. The control group: 25 healthy non-pregnant women. We determined linear blood flow rate in short posterior ciliary arteries and prothrombin ratio. Results: In group of pregnant women with PE in the III trimester we registered a decrease of average values of linear blood flow rate which in most cases increased to normal values by 6-8th months of after delivery period. These values remained decreased in 12 women that matched with the growth of prothrombin ratio. Occlusions of retinal veins has formed in mentioned cases 1.5-3.5 years later. Conclusions: Studies of linear blood flow rate in short posterior ciliary arteries and level of prothrombin ratio in pregnancy complicated by PE can detect a group of women with increased risk factor of formation of vascular pathology of posterior segment of the eye during a year after delivery.
