THIS 12-year-old boy appeared in the "Health Lodge" of a boy scout camp on Catalina Island with the chief complaint that a fly had struck him in the eye, and now it felt as if there were a worm "in there." After ineffective local therapy and 12 hours of patching, the boy returned saying that i9t felt as if "there are more worms in my eye." Examination with a hand-held magnifying glass revealed, indeed, several small worm-like organisms crawling on the bulbar and palpebral conjunctiva. A photograph was taken which showed a string of mucus under the upper tarsus, to the left of which is a small larva of the sheep botfly, Oestrus ovis (Fig 1). The use of topically administered tetracaine and small iris forceps produced 11 small larvae which were identified by Dr. John Belkin, University of California, Los Angeles, as the larvae of O Ovis (Fig 2).
