title: [Analysis of the local synthesis of Toxoplasma gondii-specific immunoglobulins in the anterior eye chamber fluid. Report of two cases].
abstract: We reported two cases strongly suspected of ocular toxoplasmosis, in which a puncture of anterior eye chamber was performed for a final verification of clinical diagnosis. In both patients, fresh focal lesions of retinochoroiditis associated with old pigmented retinal scars were diagnosed. The 62-year-old women had a serological evidence of recently acquired T. gondii infection with an increasing IgG titre of a low avidity and a presence of specific IgM and IgA antibodies. In the 13-year-old girl, an immunological profile of the chronic infection was shown, confirmed by a high IgG avidity value. In the patient with a clinical picture of recurrent congenital toxoplasmosis, intraocular production of T. gondii-specific IgG was found in anterior eye chamber. The analysis of the specific antibodies synthesis in ocular fluid by the Western blot seems to be a valuable immunodiagnostic method for a final diagnosis of ocular toxoplasmosis.
