[Amebic keratitis]. / Les kératites amibiennes.

Amoebic keratitis is an uncommon pathology mainly implicated in eye infection in contact lens wearers. The offending parasite is a free-living amoeba of the genus Acanthamoeba. Diagnosis is often delayed because clinical signs are confusing especially at the onset. Samples for parasitic tests should be taken not only for the infection site but also from the lenses and cleaning products. A standard treatment of amoebic keratitis has not been established. Several drugs are theoretically active but achieve inconsistent results. Recently keratitis has been observed at a seemingly high incidence in developing countries but epidemiologic data is still scarce.
