Abstract: A 26-year-old man residing in a village of Thai Nguyen Province, North Vietnam, visited the Thai Nguyen Provincial Hospital in July 2008. He felt a bulge-sticking pain in his left eye and extracted 5 small nematode worms by himself
half a day before visiting the hospital. Two more worms were extracted from his left eye by a medical doctor, and they were
morphologically observed and genetically analyzed on the mitochondrial cytochrome
c oxidase 1 gene. The worms were
1 male and 1 female, and genetically identical with those of
Thelazia callipaeda. By the present study, the presence of human T. callipaeda infection is frst reported in Vietnam.
Key words: Thelazia callipaeda, oriental eyeworm, eye, human case, Vietnam
