Acanthamoeba pathogen is widely distributed in the nature. However, Acanthamoeba keratitis is generally considered as a type of sight-threatening keratitis that is difficult to treat. At early stage Acanthamoeba keratitis usually shows atypical clinical manifestations, that are often misdiagnosed as viral or bacterial keratitis. Moreover, there are not approved topical anti-amoebicdrugs available up to now. We hope ophthalmological practitioners can obtain a comprehensive understanding of this infection through this book.
