These treatments for the first time have produced actual improvements in vision, rather than simply delaying or arresting the continued loss of vision characteristic of macular degeneration. A number of surgical treatments are also being investigated for macular degeneration lesions that may not qualify for laser treatment, including macular translocation to a healthier area of the eye, displacement of submacular blood using gas, and removing membranes by surgery.

The next step was shown by Robert Thomson Leiper, who described in a 1907 paper that monkeys fed D. medinensis-infected Cyclops developed mature guinea worms, while monkeys directly fed D. medinensis larvae did not.In the 19th and 20th centuries, dracunculiasis was widespread across nearly all of Africa and South Asia, though we lack exact case counts from the pre-eradication era. In a 1947 article in the Journal of Parasitology, Norman R. Stoll used rough estimates of populations in endemic areas to suggest that there could be as many as 48 million cases of dracunculiasis per year. In 1976, the WHO estimated the global burden at 10 million cases per year. Ten years later, as the eradication effort was beginning, the WHO estimated 3.5 million cases per year worldwide. Etymology
Dracunculiasis Latin name, Dracunculus medinensis ("little dragon from Medina"), derives from its one-time high incidence in the city of Medina (in modern Saudi Arabia), and its common name, Guinea worm, is due to a similar past high incidence along the Guinea coast of West Africa. It is no longer endemic in either location. Eradication
The campaign to eradicate dracunculiasis began at the urging of the CDC in 1980. Following smallpox eradication (last case in 1977; eradication certified in 1981), dracunculiasis was considered an achievable eradication target since it was relatively uncommon and preventable with only behavioral changes.
