ABSTRACT
CASO CLÍNICO: Varón sano de 55 años sin antecedente de traumatismo corneal acude a urgencias por un infiltrado en el ojo izquierdo que responde parcialmente a tratamiento antibiótico tópico. Tras la introducción de corticoterapia tópica presenta un importante empeoramiento de la úlcera. El examen directo y la tinción de Gram permiten un rápido diagnóstico de las hifas de Absidia. Presenta buena respuesta al tratamiento combinado de anfotericina y posaconazol. DISCUSIÓN: Las queratitis por Zygomycetes son raras. Es rara la afectación de pacientes sanos sin antecedentes de traumatismo corneal. El tratamiento combinado de anfotericina y posaconazol ejerce un efecto sinergico contra hongos filamentosos
CASE REPORT: A healthy 55-years-old male went to emergency due to a white infiltrate in the left eye without corneal trauma which partially responds to antibiotic treatment. The infiltrate worsened by the use of topical steroids. Direct microscopic evaluation and Gram stain are a valuable diagnostic tool for the detection of Absidia filaments. There is a successful treatment with anphotericin and posaconazole. DISCUSSION: Keratitis caused by Zygomicetes are unusual. This is a rare condition in healthy patients with no corneal trauma. The treatment with amphotericin and posaconazole are synergistic against filamentous fungi
