External ophthalmomyiasis caused by Estrus ovis.
External ophthalmomyiasis occurred in a 16-year-old white girl who was infected on Catalina Island, an endemic area for the sheep bot fly. With the patient under topical anesthesia, we isolated the larva, Estrus ovis, removed it with jewelers' forceps, and examined it with light and scanning electron microscopy. The patient responded well to a treatment regimen of corticosteroids and antibiotics.
