Preeclampsia is a disease of pregnancy classically defined by the development of new-onset hypertension and proteinuria. Serous retinal detachment is a rare complication of severe preeclampsia that is associated with a high incidence of morbidity and mortality. We present the case of a 24-year-old primigravida who was diagnosed with preeclamptic serous retinal detachment at 30 weeks of gestation that occurred in the absence of hypertension. The patient was delivered by cesarean section for fetal malpresentation and she had complete recovery of her vision by three months postpartum. Providers should exercise vigilance for preeclampsia in women presenting with new-onset visual symptoms, even in the absence of hypertension.
