But sometimes new lesions are found to occur at a distance from the old scar. The exact mechanism of these findings of reactivation in ocular toxoplasmic patients is not known. The authors studied 20 patients including acute infected patients, patients with recurrent active toxoplasmic retinochoroiditis, patients with old toxoplasmic retinal scars …
