Changes in the optic nerve sheath diameter detected by ultrasound are considered an important manifestation of increased intracranial pressure . The normal optic nerve sheath diameter measures up to 5.0 mm and an average optic nerve sheath diameter more than 5 mm is considered abnormal and elevated intracranial pressure should be suspected.Cerebral edema have been demonstrated in 71% to 100% of magnetic resonance imaging in preeclamptic patients and an increase in optic nerve sheath diameter has been described in preeclamptic females compared to healthy pregnant females Therefore, Increased optic nerve sheath diameter can indirectly reflect the state of intracranial edema that could be a part of generalized edema of preeclampsia and it could be a possible marker of generalized tissue edema and fluid overload in these patients.
