Queratitis inflamatoria por Acanthamoeba spp. Análisis estructural por microscopía electrónica de transmisión

Abstract

We present the case of a 36 years old patient, who had turbid vision and a 5 week severe optic pain in her left eye at the moment of the clinical consultation. The patient had the habit to use soft contact lens along with a non-adequate hygiene. Bacteriological and virological tests have been performed with negative results. Corneal biopsy material was extracted and observed under microscopy fresh and also with permanent colouring. Trophozoites and oocystis forms of Acanthamoeba were found using xenic culture media. Colonies were observed using optical microscope and phase contrast microscope in fresh. The amoeba ultrastructure was analyzed using Transmission Electronic Microscope.
