Abstract
Purpose: To report a case with unilateral preexisting ocular toxoplasmosis (OT) and newly occurred active retinochoroidal inflammation associated with white-centered retinal hemorrhages (Roth spots) in the healthy eye.Design: Case report.Methods: A 20 year-old man presented with a decrease of visual acuity in his right eye associated with 2+ cells in the anterior chamber. Ophthalmoscopy revealed an active retinochoroidal lesion on the upper nasal border of the optic disc associated with local hemorrhage and vitritis. The posterior pole presented white-centered flame-shaped retinal hemorrhages.Results: Toxoplasmosis serology showed an IgG titer >300IU/ml and a negative IgM titer. A complete blood count revealed no abnormalities; other serologies were negative. After 2 weeks of treatment with sulfadiazine, pyrimethamine, folinic acid and prednisone, although the peripapillary lesion was still active, the Roth spots disappeared.Conclusion: OT may be one differential diagnosis of patients suffering Roth spots in association with retinochoroidal inflammation.
