Abstract
PURPOSE: To report an uncommon case in which an insect foreign body (FB) in the cornea induced severe marginal ulcerative keratitis. METHODS: The insect body was removed during an eye examination. A shaped deep lamellar keratoplasty was then performed on the ulcerous corneal tissue and pseudopterygium. The insect FB was identified as a member of the nontoxic Diptera insect order, belonging to either the Chloropidae or Sphaeroceridae family. RESULTS: The patient recovered well after the keratoplasty, and her corneal graft was clear with significantly improved visual acuity after 2 months. CONCLUSIONS: Long-time retention of a nontoxic insect FB in the cornea could induce severe noninfectious keratitis. Individually designed deep lamellar keratoplasty successfully restored the transparency of the cornea and visual function.
