Acquired ocular toxoplasmosis. A fluorescein angiography study.

A 31-year-old man exhibited a bilateral deterioration of vision over the course of 1 week. The right fundus showed the picture of a central vein occlusion, and the left of a disseminated choroiditis. Indirect immunofluorescent testing indicated a titer of 1:2048 for toxoplasmosis. Fluorescein angiography revealed a hitherto unique picture of isolated choroidal occlusions but neither a central vein occlusion nor a disseminated choroiditis. Using only specific antitoxoplasmotic therapy, the patient regained full visual acuity on both sides. The original findings and the results of a 14-year follow-up are presented.
