—Insect parts represent an unusual type of corneal foreign body. Their history and presentation may mimic that of other conditions, as this current case demonstrates.
Report of a Case.
—A 64-year-old man was picking up tree branches in his yard when something "blew" into his right eye. He developed redness, tearing, photophobia, and a foreign-body sensation that intensified over a four-day period. His visual acuity had dropped to 20/30 OD, and a fluffy, yellow-white, mounded lesion with mildly filamentary borders and one-half stromal thickness in depth was present inferotemporally in the cornea (Fig 1). The anterior chamber demonstrated only a mild inflammatory response. Because a fungal keratitis was suspected, the cornea was scraped. Two small, brown foreign bodies could be identified in the lesion. These turned out to be insect fragments when examined under the microscope (Fig 2, top). No bacterial or fungal organisms were detected in
