What is Acanthamoeba keratitis?
Acanthamoeba keratitis is a rare but serious infection of the eye that can result in permanent visual impairment or blindness. The infection is caused when a microscopic, free-living ameba called Acanthamoeba invades the transparent outer covering of the eye called the cornea. These amebas are very common in nature and can be found in all areas of the environment, including water, soil, and air.
