BACKGROUND: In some cases of severe @entity1468 / @entity3036 , brain imaging displays signs compatible with @entity428 . We aimed to estimate the incidence of @entity428 in @entity1468 using ocular ultrasonography. METHODS: Optic nerve sheath diameter (ONSD) measurements were compared in 26 preeclamptic and 25 healthy pregnant @entity1 . For each optic nerve, two measurements were made (transverse plane and sagittal plane) using a 7.5 MHz ultrasound linear probe. Preeclamptic @entity1 were followed-up until postpartum day 7. RESULTS: Median ONSD values were significantly greater in preeclamptic @entity1 compared with healthy pregnant @entity1 at delivery (5.4 mm (95% CI: 5.2, 5.7) vs. 4.5 mm (95% CI: 4.3, 4.8), P < 0.0001). At delivery, 5/26 (19%) of preeclamptic @entity1 had ONSD values above 5.8 mm (value associated in the literature with 95% risk of @entity428 ) whereas none of the healthy pregnant group had such high ONSD values. In the preeclamptic group, ONSD decreased after the third postpartum day. ONSD values at day 7 were not significantly different from those obtained in the normal pregnancy group (P = 0.10). CONCLUSION: In about 20% of preeclamptic @entity1 , ONSD reaches values compatible with intracranial pressure above 20 mmHg. Further work is needed to confirm this incidence and to better understand the diagnostic and therapeutic usefulness of this easy-to-do monitoring technique.
