Neuroretinitis: an unusual presentation of ocular toxoplasmosis

Neuroretinitis is a clinical condition usually seen in young healthy adults that is characterized by rapid profound unilateral loss of vision. Funduscopic findings include swollen disc, splinter hemorrhages, and macular star. Catscratch fever and leptospirosis have been suggested as possible etiologies in this condition. We report a case of a patient with neuroretinitis whose only laboratory abnormality was an elevated enzyme-linked immunosorbent assay immunoglobulin G Toxoplasma titer. The patient responded favorably to treatment with clindamycin, triple sulfa, and systemic corticosteroids. We recommended toxoplasmic serology be added to the workup of patients with neuroretinitis.
