AbstractReversible posterior leukoencephalopathy syndrome (RPLS) is induced by acute cerebral edema. Its symptoms include seizures, headache, altered mental status, and visual disturbances. The clinical and radiological findings are usually transient. This report describes a case of RPLS resulting in bilateral total blindness. A 40-year-old man presented with lethargy and bilateral visual loss. He had a 20-year history of hypertension, but had never been treated. On presentation, the left eye was able to perceive light, but the right eye was not. Radiological examination showed diffuse edema in the brain, and ocular fundus examination revealed severe bilateral hypertensive retinopathy. Antihypertensive therapy improved the patient's general condition, including blood pressure. Radiological findings 5 months later showed resolution of most of the abnormal signal areas. However, total blindness had developed in both eyes by day 15, and two courses of pulsed corticosteroid therapy failed to restore the visual loss.
