Ocular parastrongyliasis (=angiostrongyliasis): probable first report of human infection from a patient in Ceylon (Sri Lanka).

What is considered to be the first case of human parastrongyliasis (angiostrongyliasis) worldwide is described from a patient in Ceylon (Sri Lanka) in 1925. It also predates the description of the parasite in humans by Chen (1935).

Third report of ocular parastrongyliasis (angiostrongyliasis) from Sri Lanka.

A further case of ocular parastrongyliasis has been seen in a patient from Sri Lanka. As it is a juvenile female worm it could not be identified to the species, but it is probably Parastrongylus (= Angiostrongylus) cantonensis which is the commonly reported species in the country. This is the third authentic case of such an infection in Sri Lanka in recent years.
