[Endogenous posterior uveitis and toxoplasma infection: a case-control study].

The present study was first carried out to evaluate the effects of toxoplasma infections on endogenous posterior uveitis in Tian in city. In this report, 118 cases of endogenous posterior uveitis and 236 clinical and health controls were studied by 1:2 pair match case-control method. The clinical controls were OPD patients without uveitis and the health controls were normal persons. The prevalence rate of toxoplasma infection in three groups were 31.4%, 11.9% and 9.3% respectively. The differences of three groups was higher significant. The odds ratio (OR) of toxoplasma infection in posterior uveitis was 3.72 (2.17-6.39). The difference of the two controlled groups was not significant. The odds ratio of toxoplasma infection in central exudative retinochoroiditis and panuveitis were 4.78 and 3.33. The toxoplasma infection was not significantly related to the optic retinitis.
