Loa loa in a Sri Lankan expatriate from Nigeria.

A worm was extracted from the subconjunctival space of the left eye in a 14-year old Sri Lankan girl, who returned to Sri Lanka in 1983 after spending six years in Nigeria. It was identified as a male Loa loa. A history of evanescent (Calabar) swellings was obtained. She also had significant eosinophilia. Microfilariae were not detected in the blood. This is the first case of Loa loa infection reported from Sri Lanka.
