Abstract
PurposeTo report panuveitis due to Toxocara, with positive Toxoplasma serology. ObservationA nine-year-old boy presented with a panuveitis, intermittent headaches, and a visual acuity of 20/400 in his left eye. Slit lamp examination showed anterior chamber cells and flare without keratic precipitates (KPs), vitreous cells and veils, and optic disc edema with a blurred fundus view. Initial lab values were positive for toxoplasmosis. Topical cycloplegic and steroid eye drops, in addition to trimethoprim/sulfamethoxazole (TMP/SMX) treatment, was initiated. Four days later, oral corticosteroids were started. As inflammation cleared, the fundus examination showed an inferior tractional detachment, leading to an ultimate diagnosis of ocular Toxocariasis.Conclusion and ImportanceHigh false positives on Toxoplasma serology and diffuse vitritis from toxocariasis limiting retinal visualization may confuse the initial diagnosis.
