title: Prevalence of congenital and acquired toxoplasmic uveitis as evidenced by two serologic methods.
abstract: Anti Toxoplasma antibodies were sought in 34 patients with uveitis and 20 healthy individuals by IHAT and IFAT. The total sero-positivity rate was 26.5%. The prevalence was significantly higher among patients with posterior (42.9%) than with anterior uveitis (7.1%) and control (10%) indicating significant role of Toxoplasma as an aetiologic agent of posterior uveitis. 14.4% of patients with seropositive uveitis were considered to be due to primarily acquired Toxoplasma infection as evidenced by their significant higher IFAT mean titre (576.7 +/- 322.1) than IHAT (48 +/- 18.5). The reported toxoplasmic anterior uveitis case is most probably secondary to posterior involvement.
