[The chorioretinal location of Toxoplasma infection]

Considered rare and occurring only in immunocompromised patients or patients with severe infection, Toxoplasma gondii chorioretinitis--as a unique presenting sign of toxoplasmosis appears to occur with increased frequency over the last few years in immunocompetent patients. The typical clinical picture (central chorioretinal lesion with recurrent vasculitic reactions) and positive IgG Toxoplasma gondii serology confirmed our diagnosis. Negative Toxoplasma IgG serology in the mothers of 2 patients excluded the possibility of congenital toxoplasmosis. Clinicians should be aware of the possibility of increased frequency of ocular toxoplasmosis in immunocompetent patients.
