[Statistical importance of tuberculosis and toxoplasmosis of the eye in recent years (1971-1974, Eye-Clinic, Davos) (author's transl)].

Tbc has not yet been eradicated in Western Europe. Among 311 human/bovin-tuberculin tested cases out of 500 patients with uveitis (1971-1974), 37-50% (average age 40-45 years) reacted highly positive. Chorioretinitis disseminata and periphlebitis retinae (Eales' disease): 90% positive. The criteria for a long term tuberculostatic treatment are exposed. 20% of all cases of uveitis and 90% of Jensen Retinochorioditis have been interpreted as caused by toxoplasmosis. 75% are relapses. The gigantic toxoplasmotic lesions of the eyeground is stressed. As a rule low Sabin Feldmann titers are found. Quantitative serology is valuable. In the closing discussion the immunologically well known adjuvans-effect of Koch's bacillus-extract is supposed to be of importance in highly tuberculin positive uveitis.
