Ocular larva migrans (OLM), also known as ocular toxocariasis, is the ocular form of larva migrans syndrome.It occurs when roundworm larvae invade the human eye. OLM infections in humans are caused by the larvae of Toxocara canis (dog roundworm), Toxocara cati (feline roundworm), Ascaris suum (large roundworm of pig), or Baylisascaris procyonis (raccoon roundworm).
