ABSTRACT Diagnosis of ocular toxoplasmosis is usually based on the characteristic necrotizing retinochoroiditis in combination with positive serologic titers. We reported a 54-year-old female patient which the fundus lesions were not so typical and serologic titer was markedly low. The diagnosis was made by isolation of Toxoplasma gondii from subretinal content. Histological study by Giemsa stain and ultrastructural features demonstrated by electron microscopy confirmed the identification.
