ADULT OCULAR TOXOPLASMOSIS

Abstract

WITHIN recent years the question of the toxoplasmic etiology of uveitis has been the subject of various surveys and investigations. Frenkel⁶(1951) found a correlation between skin test reactions and uveitis in a small group of hospital patients in California. Frenkel and Friedlander⁷(1952) presented the results of the dye test of Sabin and Feldman¹³on the same patients; they found most of the antibody titers to be low and postulated that the parasites could reside in the eye over long periods without stimulating antibody production. Hogan⁸(1951), because of lack of correlation between serological findings and adult uveitis, considered it unlikely that many cases of adult uveitis are due to toxoplasmosis. Hogan, Thygeson, and Kimura⁹(1952) later found the incidence of positive dye test reactions higher in patients of all age groups with chorioretinitis than in other groups, but in most cases the titers
