초록
목적: 결막하를 침범한 동양안충 1예를 보고하고자 한다. 증례요약: 52세 남자가 1달 전부터 발생한 좌안 이물감을 주소로 내원하였다. 세극등 현미경 검사상 좌안 하측 안구결막하에 약 10 mm 길이, 약 0.3 mm 너비의 하얀색의 반투명한 기생충이 살아 움직이는 모습이 관찰되었다. 전방 및 안저에는 특이소견이 관찰되지 않았다. 기생충이 위치한 결막 부분을 약 5 mm 절개하였으며 그 부위를 벌려 겸자를 이용하여 결막 밑에 위치한 기생충을 천천히 잡아당겨 제거하였다. 그 뒤 결막 밑부분을 생리식염수로 세척하였다. 또한 결막낭에서 기생충 5마리가 추가로 발견되어 제거하였다. 기생충은 Thelazia callipaeda로 동정되었으며, 제거 후 1달 동안 외래 추적관찰을 시행하였으나 추가적인 기생충은 발견되지 않았다. 결론: 동양안충의 안내 침범은 흔하지 않은 것으로 알려져 있지만 저자들은 결막낭에 충이 다수 존재하면서 동시에 결막하를 침범한 동양안충을 경험하였기에 보고하는 바이다.
Abstract
Purpose: To report one case involving Thelazia callipaeda subconjunctival infestation. Case summary: A 52-year-old man came in with left eye discomfort that started about a month prior to hospital visit. Slit lamp examination identified a live white translucent parasite about 10 mm in length and about 0.3 mm in width moving under the lower left eye subconjunctiva. No other abnormal findings were found in the front or fundus. An incision of about 5 mm in the conjunctiva where the parasite was located was carried out, and after opening the area, the parasite was slowly pulled out using a clamp. Then, the bottom of the conjunctiva was washed with normal saline. Further, five additional parasites were found in the conjunctival sac and were removed. The parasite was identified as Thelazia callipaeda, and through outpatient follow-up for 1 month after removal, additional parasites were not found. Conclusion: The authors report this case of intraocular Thelazia callipaeda infestation because it is not known to be common; however, the authors witnessed a number of parasites in the conjunctival fornix, as well as Thelazia callipaeda in the subconjuctiva.
