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
