Abstract: Preeclampsia (PE), a hypertensive disorder manifesting after 20 weeks of gestation, poses significant risks to both maternal and fetal health. This prospective case - control study, conducted from January to September 2023, aimed to evaluate the predictive potential of ophthalmic artery Doppler waveform analysis for PE outcomes. Thirty pre - eclamptic cases and 30 matched pregnant controls were included, with Doppler parameters recorded using a GE Voluson S8 Ultrasound machine. The study found that various Doppler parameters, including mean peak systolic velocity, pulsatility index, resistivity index, and peak ratio, significantly differed between pre - eclamptic cases and controls (p - value < 0.001). Notably, resistivity index and peak ratio effectively distinguished between mild and severe PE, exhibiting high sensitivity and specificity. A Doppler cut - off of 23.3 cm/s demonstrated modest sensitivity (78.2%) and specificity (83.9%) for early - onset PE prediction. Discussion highlights the higher mean age of mothers with PE and the significance of lower impedance in the ophthalmic artery, indicating abnormal hemodynamics beyond normal vasodilatation. Unlike healthy pregnancies, PE - related impedance indices decrease alongside lower peak systolic velocity. In conclusion, ophthalmic artery Doppler emerges as a valuable, non - invasive tool for diagnosing both overall and severe preeclampsia. Parameters like resistivity index, peak ratio, and pulsatility index exhibit high sensitivity and specificity, making ophthalmic artery Doppler a potential screening method for early detection of hemodynamic changes associated with preeclampsia in high - risk cases.
