Abstract

Case report: The case concerns a 6 year-old girl who refers a 6-month history of decreased visual acuity in the right eye. The only relevant data during interrogation was contact with dogs. The initial diagnosis was a retinal hamartoma. The patient was studied with complete blood count, blood chemistry, magnetic resonance imaging, and A and B-scan ultrasonography. Anti-Toxocara canis antibodies were measured (IgG 24.5 U, normal range 0-9 U; IgM and IgA < 2.5 U within normal range). Discussion: After a comprehensive evaluation that ruled out a retinoblastoma, along with laboratory tests and imaging findings, we established a diagnosis of a central granuloma with centripetal vitreoretinal contraction caused by ocular toxocariasis.
