What Out Of This Flies If You Don't Want Worm Living In Your Eye

A man didn't know why he continuously suffered from hazy vision and kept seeing dark spots.
When he got diagnosed, the doctor said he had a parasitic worm in his eye that was eating away at his retina.
While hearing about a worm eating a person's eye may be stomach-churning, experts say parasitic infections occur frequently around the world -- and even in the United States. Such cases often serve as an unsettling reminder that despite modern medicine, humans are not always at the top of the food chain.
Though the eyes are not usually the most commonly infected organs, eye worms are certainly not unheard of.
"The three most common parasitic infections affecting the eyes are toxocariasis, loaiasis [infection with the Loa loa worm] and African river blindness," said Dr. Peter Hotez, chair of the Department of Microbiology, Immunology and Tropical Diseases at George Washington University in Washington, D.C.
An illness of humans caused by larvae (immature worms) of either the dog roundworm (Toxocara canis), the cat roundworm (Toxocara cati) or the fox roundworm (Toxocara canis). Toxocariasis is often called visceral larva migrans . 
Depending on geographic location, degree of eosinophilia, eye and/or pulmonary signs the terms ocular larva migrans, Weingarten's diseaseFrimodt-Møller's syndrome, and eosinophilic pseudoleukemia are applied to toxocariasis. 
Other terms sometimes or rarely used include nematode ophthalmitis, toxocaral disease, toxocarose, and covert toxocariasis. This zoonotichelminthicinfection is a rare cause of blindness and may provoke rheumaticneurologic, or asthmatic symptoms. 
Humans normally become infected by ingestion of embryonated eggs (each containing a fully developed larva, L2) from contaminated sources (soil, undercooked meat, fresh or unwashed vegetables.).

Loa loa filariasis
A skin and eye disease caused by a nematode worm Loa loa, which you can get from the bite of a deer fly or mango fly. Loa loa does not normally affect one's vision but can be painful when moving about the eyeball or across the bridge of the nose. It can cause red itchy swellings call "Calabar swellings". This can be treated with diethylcarbamazine (DEC) or surgery to remove the worms.

Onchocerciasis also known as river blindness
 A disease caused by infection with the parasitic worm Onchocerca volvulus. Symptoms include severe itching, bumps under the skin, and blindness. It is the second most common cause of blindness due to infection, after trachoma.

The parasite worm is spread by the bites of a black fly of the Simulium type. Usually, many bites are required before infection occurs. These flies live near rivers, hence the name of the disease. Once inside a person, the worms create larvae that make their way out to the skin. Here, they can infect the next black fly that bites the person. There are a number of ways to make the diagnosis including: placing a biopsy of the skin in normal saline and watching for the larva to come out, looking in the eye for larvae, and looking within the bumps under the skin for adult worms.

Cordylobia anthropophaga, the mango flytumbu flytumba flyputzi fly, or skin maggot fly, is a species of blow-fly common in East and Central Africa. It is a parasite of large mammals (including humans) during its larvalstage. C. anthropophaga has been endemic in the subtropics of Africa for more than 135 years and is a common cause of myiasis in humans in the region.
