Natural honey-induced Acanthamoeba keratitis

Abstract

Natural honey in spite of its usefulness is known to contain certain microorganisms. In the present study, we describe a case of Acanthamoeba keratitis after using topical honey administered by a traditional medicine therapist. A 32-year-old male came with red eye and blurred vision. The pain and other symptoms became more severe after the 1st week, with appearance of radial perineuritis at the cornea. A repeated interview revealed that 1 week before appearance of ocular symptoms, the patient had instilled a drop of natural honey in his left eye. Confocal microscopic cornea imaging demonstrated cyst and trophozoite of Acanthamoeba in the corneal stroma.
