OBJECTIVES: This study aimed to compare changes in ultrasonic Doppler parameters, particularly the peak ratio (PR) of the ophthalmic artery (OA) and optic nerve sheath diameter (ONSD), in pregnancies complicated by fetal growth restriction (FGR). Furthermore, it sought to evaluate differences in these parameters across various subgroups and analyze the cut-off value of PR for predicting delivery within 1 week in pregnancies complicated by FGR.
METHODS: A total of 62 pregnant women in the mid-to-late stages of gestation were enrolled, comprising 31 participants in the FGR group and 31 in the control group. The general conditions, pregnancy outcomes, Doppler parameters of the OA, and ONSD were compared between the two groups. Comparative analysis was performed to investigate differences in OA Doppler parameters and ONSD across FGR subgroups. The predictive value of PR for delivery within 1 week was assessed using the area under the receiver operating characteristic curve.
RESULTS: The PR of the OA was significantly elevated in the FGR group compared to the control group, demonstrating a statistically significant difference. The threshold PR value for predicting delivery within 1 week was 0.565, with a sensitivity of 0.88 and a specificity of 0.58.
CONCLUSIONS: The PR value of the OA in pregnant women with FGR is significantly increased and may serve as a reliable predictor for pregnancies complicated by FGR.
