Palpebral myiasis.
Myiasis is most prevalent in Mexico, central and south America, tropical Africa, and the southwestern United States. Although dermal myiasis is rare in most of the United States, it is a disorder that may be seen in international travelers. In the United States, external myiasis is usually caused by the cattle botfly. We report here a case of ophthalmomyiasis involving the left upper eyelid of a child. We examined a six-year-old boy who presented to the Massachusetts Eye and Ear Infirmary (MEEI) in September 1998. He complained of persistent swelling of his left upper eyelid for the previous ten days. The edema and erythema were unresponsive to warm compresses and oral antibiotics. Ocular examination revealed a mild preseptal cellulitis of the left upper eyelid with a small draining fistula. On slit-lamp examination, we found one larva protruding intermittently from the fistula site. The larva was extracted with forceps, wrapped in a moist towel and sent in a jar to the parasitology laboratory. The specimen was identified as a Cuterebra larva by a parasitologist at the Harvard School of Public Health. One week later, the patient's eyelid edema and erythema had completely resolved.
