“…One case was a mixed case of anterior and posterior internal ophthalmomyiasis, 125 whereas the remainder solely involved posterior structures. The majority of the cases originated in the United States (53%), 36,43,48,87,94,112,131,170 followed by Europe (27%). 61,81,141,142 Sixteen of the 18 cases had visual outcomes documented: 31% had excellent outcomes (6/6e6/7.5) 48,94,110,131,141,142 ; 18.75% reasonable outcomes (6/12e6/18) 110,112 ; and the remaining 50% had poor outcomes with 25% having perception of light vision, 6% having NPL vision, and 18.75% undergoing enucleation.…”

Eye injury remains the leading cause of monocular blindness in children despite 90% of injuries being potentially preventable. Children interact with animals in a variety of situations, and the associated dangers may be underestimated. Animals are capable of causing ocular and adnexal injuries that are cosmetically and visually devastating. We examine the current literature regarding the nature and severity of animal-inflicted ocular and adnexal injuries in children.

“…This treatment halts additional damage from further larval migration 3,4,6,17 . The use of the laser results in minimal inflammation because the laser energy denatures the organism's proteins resulting in diminished antigenic stimulation 3,4,15,16 . If the larva is dead or immobile and causing inflammation in the face of medical treatment, it should be surgically removed 2,3,9,18,19 .…”

Unilateral chorioretinitis caused by ophthalmomyiasis interna posterior in a 5-month-old, female spayed Dachshund is reported. Larva removal by pars plana vitrectomy was performed after an unsuccessful photocoagulation of the organism. The larva was intact after surgical removal and was identified as a first stage instar Cuterebra spp. larva. The eye remains visual and comfortable with no signs of residual or recurrent inflammation postoperatively. This report describes, for the first time, the successful surgical retrieval of an intravitreal fly larva in a dog using vitrectomy techniques without sacrificing either the globe or vision, and taxonomic identification of the parasite.

“…The clinical signs and prognosis may vary depending upon the viability of the larva and its location in the eye 7 . It has been proposed that larvae within the vitreous incite less inflammation because the avascular vitreous may protect the eye from toxic or immunologic damage from the dead larvae 24,25 . The inflammation may be caused by toxic or enzymatic materials that are produced by the larva 14 or by an immunologic reaction 26 .…”

“…Photocoagulation with an argon laser of live subretinal larvae causes only minimal inflammation in human patients. The minimal inflammation may be a result of the denaturing of the larval proteins, which are then less antigenic 25,32 . The limited number of reported cases of ophthalmomyiasis interna in the veterinary literature makes any conclusions regarding the best therapy difficult.…”
