Abstract

To describe the clinical presentation of migratory nematodes and to outline a simple strategy to ensure capture. Retrospective case series. Two consecutive patients with suspected migratory nematodes were treated promptly by strategic placement of a pharmacological barrier in the forniceal conjunctiva using 1% lidocaine with epinephrine to block the routes of retreat and to immobilize the worms for controlled retrieval. Two live nematode worms, one subcutaneous dirofilaria and one subconjunctival Loa loa, were successfully removed. A sense of urgency is conveyed to isolate the migratory worm while it is still visible and residing in a location for easy surgical removal. The retreat of the worm to the deeper, inaccessible orbit is prevented by strategic placement of a perimeter of anesthetic.

Anthelmintics (ASM)

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
