Abstract

La queratitis producida por Nocardia spp es raramente reportada en el mundo por lo que su incidencia no está aún bien establecida. En el presente estudio se reporta el primer caso de queratitis por Nocardia brasiliensis en Paraguay en un paciente de sexo masculino, de profesión jardinero, procedente de la ciudad de Asunción, y con antecedente de traumatismo con rama de arbusto quince días antes de la consulta. El paciente acude al servicio de Oftalmología del Hospital de Clínicas, debido a ojo rojo, agudeza visual disminuida e intenso dolor en el ojo izquierdo con una semana de evolución. Se realiza tratamiento con la aplicación de colirio reforzado de gentamicina 14 mg/ml y cefazolina 50 mg/ml, cada una hora, observándose mejoría de los síntomas y de la agudeza visual a los 10 días de seguimiento. La evolución clínica en queratitis a Nocardia spp es buena siempre que el diagnóstico etiológico se realice sin demora y correctamente. Es muy importante diferenciar los bordes de las lesiones de la úlcera de córnea producidas por hongos, bacterias filamentosas y otras bacterias, además considerar la presencia de lesiones satélites.
