Purpose. To report a case of conjunctival granuloma formation in response to lodgment of an insect wing.
Method. Case report and review of the literature.
Results. Granuloma formation in the conjunctiva can occur following lodgment of an insect wing. This can cause the patient chronic redness, discharge, and discomfort.
Conclusions. Small foreign bodies with relatively little mass and large surface area can evade the normal protective mechanisms for removal of a foreign body and give rise to a chronic inflammatory response.
Granuloma formation can occur in the conjunctiva as an acute or chronic inflammatory response to foreign materials lodged in it. Inciting agents for granuloma formation in the conjunctiva that have been reported in literature include cilia, caterpillar hair, and natural and synthetic fibers. We herein report a case of conjunctival granuloma secondary to lodgment of an insect wing within the tarsal conjunctiva. To the best of our knowledge, this is the first report in literature of conjunctival granuloma formation in response to an insect wing.
