Retinal detachment is a rare complication of preeclampsia. In 24,920 consecutive deliveries from 1970 at the Vancouver General Hospital, preeclampsia was diagnosed in 1435 patients (5.76%), and in 2 cases serous retinal detachment occurred. Despite spontaneous retinal reattachment, focal pigmentary macular disturbances with visual impairment may persist. Serial examination of the optic fundi, visual acuity, and central visual field assessment by Amsler grid are simple, indispensable tests that will help identify the visually threatened patient with severe preeclampsia. Timely obstetric intervention in severe cases is suggested.
