Fly larva adherent to corneal endothelium.
Anterior ophthalmomyiasis is a rare condition in which a fly larva invades the globe, causing iridocyclitis and sometimes subluxation of the lens. Humans are accidental hosts in whom such larvae, after entering the eye, undergo little development. We report a case in which the first larval stage of a rodent or rabbit botfly, Cuterebra sp., invaded the anterior chamber, produced a transient iridocyclitis, and adhered to the posterior cornea where it remained as a dead, slightly atrophic body. Identification of the organism was made by slit-lamp and specular photomicrographs. Tapering doses of topical corticosteroids controlled the inflammation. During 27 months of observation the larva changed only slightly in appearance, the surrounding corneal endothelium remained normal, the cornea remained clear, and the visual acuity remained 20/20.
