Toxoplasmosis is the most common retinal infection in the United States, and it can severely impact vision. We used data from population-based studies, outbreaks, and the U.S. census to estimate the burden of infection and ocular toxoplasmosis. We estimate that 1,075,242 persons are infected with , 21,505 persons have ocular lesions (both asymptomatic and symptomatic), and 4,839 (range = 2,150–7,527) persons develop symptomatic ocular toxoplasmosis each year in the United States. Toxoplasmosis contributes a significant burden to eye disease in the United States.
