El diagnóstico clínico inicial fue el de un hamartoma retiniano. Se realizó un abordaje con estudios de biometría hemática, química sanguínea, resonancia magnética de cráneo y ultrasonido en modo AB. Se solicitó posteriormente determinación de anticuerpos para Toxocara cani (inmunoglobulina [Ig] G 24.5 U, valores de referencia 0-9U; IgM e IgA &lt; 2.5 U, dentro de parámetros).  Discusión: Tras haber realizado el abordaje de la paciente de manera integral descartando un retinoblastoma, sumado a los hallazgos clínicos y de laboratorio, se establece diagnóstico final de granuloma central por toxocariasis con contracción vitreorretiniana centrípeta. La paciente se encuentra bajo vigilancia y seguimiento en el hospital.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[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 &lt; 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.]]></p></abstract>
