Infection with Larva of dog or cat roundworm (toxocaria cati or canis) ; feces ingestion or dirt intake is the usual source; visceral larval migrans occurs and hyper-eosinophilic syndrome as well; ocular involvement can cause blindness; treatment is corticosteroid usually not anti-helminthic antibiotic
