Optic Nerve Sheath Diameter in Preeclampsia

Evaluation of Intracranial Pressure With Optic Nerve Sheath Diameter Measurement in Women With or Without Preeclampsia

Severe preeclampsia is associated with an elevation in intracranial pressure (ICP). Optic nerve sheath diameter is a non-invasive surrogate of invasive ICP measurement. This study targets to evaluate the ICP in patients with or without preeclampsia.

MRI studies have shown that brain edema due to an elevation in ICP develops in up to 70% of women with preeclampsia. Optic nerve sheath diameter is used to estimate the ICP and has been shown to correlate well with invasive ICP measurement. The present study aims to compare ICP using optic nerve sheath diameter in women with or without preeclampsia.
