White dot syndromes are a group of inflammatory chorioretinopathies that share pathologic features involving lesions in the external retinal layers and choroid. This report describes a case of acute visual loss due to a white dot syndrome superimposed on severe diabetic retinopathy (DR), leading to a challenging diagnosis. A 53-year-old man with severe DR was referred with acute unilateral vision loss, with the presumptive diagnosis of diabetic macular edema. The clinical examination and complementary diagnostic tests revealed the absence of diabetic macular edema but showed disruption of the outer retinal layers and choroidal thickening. Laboratory and imaging testing excluded other etiological factors, so an inflammatory chorioretinopathy superimposed on severe DR was considered. Following the initial presentation, without any therapeutic intervention, rapid anatomical and functional improvement was objectified. This case demonstrated that in rare cases, an inflammatory chorioretinopathy may go unnoticed in the presence of preexisting retinopathy, and the true cause of vision loss may initially be misdiagnosed.
