On October 26, 1987, the authors encountered a case of human thelaziasis involving both eyes. The case in Chollapuk-do, Korea, a farmer aged 23, complained of mild lacrimation for 3 weeks followed by 1 week duration of foreign body sensation in both eyes prior to examination of eyes. The conjunctivae of both eyes appeared slightly reddened. No other abnormalities were noticed. Total 6 worms, one male and two females from each eye, were removed, parasitologically studied, and identified as Thelazia callipaeda Railliet and Henry, 1910.
