[Multifocal choroidal ischemia in preeclampsia: report of two cases]. / Ischémie choroïdienne multifocale au cours de la toxémie gravidique : à propos de deux cas.

INTRODUCTION: Multifocal choroidal ischemia is a complication of severe hypertension, notably in preeclampsia. It is a rare phenomenon due to multiple choriocapillaris occlusions. CLINICAL OBSERVATIONS: We report the cases of two patients, age 28 and 32 years, 34 and 26 weeks since last menstrual period, respectively. The first had controlled preeclampsia under treatment. The second had developed Hemolysis, Elevated Liver enzymes, Low Platelet count (HELLP) syndrome complicated by in utero fetal death. Both patients reported visual loss. Comprehensive ophthalmological examination and fluorescein angiography confirmed the diagnosis of multifocal choroidal ischemia, in the acute stage in the first patient and cicatricial in the second. CONCLUSION: Acute choroidal ischemia is an ocular vascular syndrome which must be ruled out by systematic examination in any preeclamptic patient, so as to make the diagnosis and begin treatment early.
