Diffuse Unilateral Subacute Neuroretinitis in South America

Abstract

We describe two cases of diffuse unilateral subacute neuroretinitis in South America. These Brazilian patients presented with subretinal worms similar in size to those described in the southeastern United States. This is the first report, to our knowledge, of diffuse unilateral subacute neuroretinitis occurring outside the United States and Caribbean Islands.
