ABSTRACT

Visceral larva migrans is the most common infection caused by zoonotic nematodes in many developing countries, was described in 1950 but for years it was considered rare in children. It is caused by the ingestion of larvae of Toxocara through contaminated food or geophagy, adult worms live in the small intestine of dogs and cats and clinical manifestations depend on the organ affected, of helminth migration or intensity infection. It may be an asymptomatic infection or produce manifestations or ocular larva migrans visceral. It is more common in preschool and school. Clinical manifestations of ocular larva migrans typically produce strabismus, endophthalmitis, chronic inflammation of the tissues of the posterior or granulomas chronic uveitis and retinal disturbances which can lead to blindness in the affected eye. The existence of leukocoria is a warning sign which should make differential diagnosis with retinoblastoma because this is the most common intraocular tumor in childhood, accounting for 4.3% of cancer in children. It most often occurs unilaterally and may also have uveitis and retinal detachment and has a current survival of 90% if detected early. A case report of a patient with ocular larva migrans in which it was necessary differential diagnosis with retinoblastoma.
