Fig. 9. A. A small focus of Toxoplasma retinochoroiditis adjacent to a healed retinochoroiditic scar near the equator in the right eye of a 23-year-old man. The Toxoplasma antibody titer IgG was 1:64 (indirect fluorescence antibody test). Such small lesions with minimal vitreous reaction may be observed and followed without treatment. B. Left eye of same patient showing a healed pigmented retinochoroiditic scar. Recurrences of Toxoplasma retinochoroiditis are not associated with an increase in antibody titer (B, Courtesy of Dr. John Cavender)
