Purpose: To report Two cases of Thelazia callipaeda from the canaliculus after irrigation of lacrimal duct
Case Summary : A 82-year-old male patient and a 64-year-old male patient presented with symptoms of epiphora, itching, and a sense of foreign body. Patients did not report having had flies in their eyes, and keep animals such as dogs, cats, and cows. After the irrigation of lacrimal duct, actively moving worms were identified in conjunctiva and were extracted with forceps. Extracted worms were a white thread-like round worm, 10-15 mm in size. The presence of the Thelazia callipaeda worms was confirmed by light microscopic findings. The patients’ symptoms resolved and there were no recurrences.
Conclusions : Thelazia callipaeda usually lie in the ocular surface, causing ocular surface disease. After removal the worms, symptoms are resolved. For treat and prevention of the thelaziasis, the continious study about life cycles and routes of infection of Thelazia callipaeda is necessary.
