  Operation Eyesight - River Blindness
Onchocerciasis is often called "river blindness" and occurs in central Africa and central America near rapidly flowing rivers and stream, where the species of fl fly that transmits the disease is most often found.
Currently, river blindness is managed with chemicals to stop the nematodes from reproducing and with insecticides to kill the fl flies that carry the worms.
River blindness is the world’s second leading cause of infectious blindness and is found in more than 36 countries, notably in the central part of Africa and in South America.

Clinical trials in Nigeria have provided new clues to the treatment of river blindness, a disease caused by a worm that infects 18 million people.
Ivermectin, the established drug which successfully treats the infection, is known to be effective against minor damage caused to the front of the eye by the worm, but until now scientists had very little clear evidence about the drug's role in preventing more serious effects of infection, in particular damage to the optic nerve.
The researchers say that sustained, annual doses of ivermectin could prevent 'a substantial proportion' of river blindness in the savanna habitat where the trial was done.

River blindness, a devastating tropical disease that affects 18,000,000 people in Africa, the Arabian peninsula, and Latin America, is caused by parasitic worms that burrow into the skin and release millions of tiny offspring that spread throughout the body.
Instead, it is the worms' symbiotic cargo of Wolbachia bacteria that provokes the body's severe inflammatory response, leading to blindness and serious skin disorders.
With the close connection between worm and bacteria in mind, the researchers devised experiments to uncover Wolbachia's exact role in the development of river blindness.
