Prevalence of congenital and acquired toxoplasmic uveitis as evidenced by two serologic methods.
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.
