Predictive value of second-trimester ophthalmic artery Doppler for identifying women at risk for preeclampsia

Figure 2 Doppler imaging of the ophthalmic artery obtained from a patient who subsequently developed preeclampsia demonstrates an elevated second systolic peak velocity of 32 cm/second and a first systolic peak velocity of 52 cm/second, resulting in an increased peak ratio. EDV: End-diastolic velocity; P1: First systolic peak velocity; P2: Second systolic peak velocity.
