Maternal Ophthalmic Artery Resistance in Pregnancies With Pre‐Eclampsia Compared to Normotensive Participants

This study found significant differences in the ophthalmic artery Doppler indices between pregnant participants with PE and those with normal blood pressure. Specifically, lower RI, PI and S/D ratio, as well as a higher EDV, were observed in the PE group. These findings suggest altered blood flow dynamics in PE. Clinically, spectral Doppler ultrasound of the ophthalmic artery could be a useful, non-invasive tool for detecting and monitoring haemodynamic changes in PE. Given its accessibility and repeatability, it could help identify PE earlier, especially in settings where more advanced diagnostic tools are unavailable.
