Coats' disease in a renal transplant recipient.

We report the first case, to our knowledge, of Coats' disease, an idiopathic exudative retinopathy, in a renal transplant recipient. Due to certain similarities in clinical presentation and confounding factors present in patients who have received kidney allografts, our patient was originally misdiagnosed as having cytomegalovirus retinitis. We emphasise the significance of this diagnostic distinction and the association of this retinal syndrome with renal disease.
