In vivo diagnostic imaging of ocular toxocariasis.

摘要

Toxocariasis was first reported in the early 1950s.1 Distribution is worldwide but the incidence is highest in the southeastern United States, Puerto Rico and the West Indies.2 Serological surveys have indicated that from four to 30 per cent of people in the United States are infected wiui the parasite.2 Two clinical diseases are described: visceral larva mig-rans (VLM) affecting multiple systemic organs and ocular larva migrans (OLM) affecting the eye.1 Ocular involvement appears clinically as a granuloma of the posterior pole or peripheral retina, or as an endophthalmitis. Ocular toxocariasis carries a poor visual prognosis secondary to its widespread tissue involvement.
