Summary of Loa loa (Eye worm)
Loa loa is the filarial tissue nematode (roundworm) species that causes Loa loa filariasis. It is commonly known as the "eye worm" as the worm may be visualized crawling in the patient's conjunctiva. If a parasite stops in one place for a short period of time, the human host will suffer from local inflammation known as Calabar swellings. These are localized, tense, inflammatory pruritic subcutaneous edema seen in joints of extremities.Transmission is via the bite of a fly (deer fly, mango fly, horse fly). Treatment is with diethylcarbamazine. Its geographic distribution includes Africa and India.
