Retinal Detachment is a rare complication of preeclampsia or eclampsia during pregnancy. The incidence of serous retinal detachments is approximately 1% for severe eclampsia and approximately 10% for eclamptic patients. Choroidal ischemia and infarction may be the cause of serous retinal detachment. Retinal detachment will spontaneously resolve within few weeks, and they often did not have any sequelae. However, focal pigmentary macular disturbance with visual impairment had been reported after retinal detachment resolution. Medical treatment with antihypertensive drugs and steroids may be helpful. We reported a rare case of retinal detachment due to severe precelampsia and mild pigmentary macular change with poor vision recovery was found by follow-up examination. To the women having suffered from preeclmapsia or eclampsia during pregnancy and then complained of blurred vision, the possibility of retinal detachment should be considered and fundus examination should be performed.
