MICHEL-ESPINOZA, Luis R.; ARIAS-CABELLO, Belina; MORENO-PARAMO, Daniel y ARROYO-YLLANES, M. Estela. Ocular toxocariasis simulating a retinal hamartoma. A case report. Rev. mex. oftalmol [online]. 2021, vol.95, n.6, pp.285-288. Epub 16-Dic-2021. ISSN 2604-1227. https://doi.org/10.24875/rmo.m21000159.
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.
