Comparison of maternal ophthalmic arteries resistance in pregnant mothers with pre-eclampsia with mothers with normal blood pressure

Abstract

Preeclampsia is a serious challenge for both mother and fetus. This pregnancy complication is associated with hemodynamic changes that affect the ophthalmic artery, which is a branch of the internal carotid artery. Doppler ultrasound of the ocular artery (OAD) is a suitable tool Which can show hemodynamic changes in preeclampsia. In this study, we aim to evaluate changes in ocular artery resistance in pregnant women with preeclampsia compared to pregnant women with normal blood pressure. Materials and Methods: In this case-control study, the hemodynamic changes of Ophthalmic arteries were studied by color doppler ultrasonography in 50 normotensive pregnant women and 50 gravidas with preeclampsia, peak systolic velocity (PSV), end diastolic flow velocity parameters (EDFV), S/D ratio, resistance index (RI) and pulsatility index (PI) were measured and then the study data were analyzed by Two independent sample T-test. Results: Comparison of these findings in the two groups for the peak systolic velocity (PSV) parameter did not show a statistically significant difference (p> 0.05). But Doppler findings were significantly lower in pregnant women with preeclampsia than normal blood pressure pregnant women for resistance index (RI) (p = 0.008) and pulsatility index (PI) (p < 0.001) and S/D Ratio (p = 0.002) and was higher for End-Diastolic Velocity (EDV) (p = 0.032).
