TOXOPLASMA CHORIORETINITIS IN ADULTS

Abstract

ORGANISMS morphologically indistinguishable from Toxoplasma have been found in chorioretinal lesions in 53 eyes in the Registry of Ophthalmic Pathology. Included in this group are 41 eyes mentioned in a preliminary report.¹ The patients were from 14 to 83 years of age at the time of enucleation, and, although eye symptoms had been observed for from a few weeks to 32 years, the earliest history of onset was at 12 years, in one instance. On the other hand, six patients had a history of onset in the seventh decade of life, and two, in the eighth. Thirty-seven patients were male; 15 were female, and the sex of one patient was unknown. The preponderance of males may be accounted for by the military source of much of the material examined. Forty-nine of the patients were white; 3 were Negroes, and 1 was a Filipino. The geographic distribution was wide. Specimens
