PURPOSE: We report a case of unilateral exudative retinal detachment in a patient with thrombotic thrombocytopenic purpura (TTP), without associated hypertension, successfully treated with plasmapheresis. CASE REPORT: A 46-year-old woman with a medical history of TTP presented with unilateral exudative retinal detachment. Biological and radiological assessment eliminated other causes of exudative retinal detachment, including hypertension. Plasma exchange was performed, followed by a rapid improvement in visual acuity and total disappearance of serous detachment. CONCLUSION: Exudative unilateral retinal detachment is a rare complication of TTP and can be successfully treated by plasma exchange.
