Outer retinal layer toxoplasmosis.

It is widely held that ocular toxoplasmosis (1) involves inner retinal layers and (2) shows marked vitreous cellular reaction. This article reports on punctate outer retinal layer toxoplasmosis, a subset of ocular toxoplasmosis characterized by grey-white lesions of deep retina and retinal pigment epithelium, and associated with little or no overlying vitreous reaction. Acute lesions may resolve and become fine punctate white dots. Recognition of this uncommon presentation of toxoplasmosis is important, since this may allow for potentially efficacious therapy.
