Ophthalmic Artery Doppler Indices at 11-13 Weeks of Gestation in Relation to Early and Late Preeclampsia.

Preeclampsia (PE) remains a leading cause of maternal and fetal morbidity and mortality. Early prediction is crucial for timely intervention and management. The ophthalmic artery (OA) Doppler assessment in the first trimester has emerged as a potential tool for predicting PE, particularly early PE, with delivery <37 weeks of gestation. This study aimed to evaluate and compare the relationship of ophthalmic artery Doppler parameters at 11-13 weeks of gestation with the subsequent development of early and late PE. A prospective observational analysis was conducted on 4054 pregnant women, including 114 who developed PE. OA Doppler assessment of the pulsatility index (PI) and peak systolic velocity (PSV) ratio, mean arterial pressure (MAP), uterine artery PI (UtA-PI), and serum placental growth factor (PlGF) were compared between women who later developed early PE and late PE with those who did not develop PE. In the PE groups, particularly those with early PE, compared to the no PE group, the OA PSV ratio and UtA-PI were higher and PlGF was lower. A first-trimester OA Doppler assessment shows promise as a non-invasive method for the prediction of PE. Further prospective, multicenter studies are needed to validate these findings.
