Abstract

Purpose: The purpose of the authors was to report the first case of ciliated protozoa diagnosed in corneal scrapings from keratitis from a hydrophilic contact lens wearer. Methods: The laboratorial research confirmed polymicrobial contamination with bacteria, fungi and protozoa. The results: A 27-year-old Brazilian woman was presented in the ophthalmology ambulatory with complaints of red eye, foreign body sensation, tearing and decreased visual acuity in the left eye during the use of hydrophilic contact lenses. A ciliated protozoan suggestive of Balantidium coli was found in the examination of corneal scrapings (Giemsa). Trophozoites of the ciliated protozoa were also observed in the direct examination and culture of the lens solution, while Acanthamoeba trophozoites were diagnosed only in the culture of the solution. The other agents were diagnosed by culture of material collected from the affected cornea and contact lens. Conclusion: it is necessary to consider ciliated protozoa as potential contaminants of solutions for hydrophilic contact lenses and possible infectious agents of the cornea since there are no reports in the literature of this fact.
