SANABRIA, R et al. Queratitisdue to Nocardia brasiliensis.First reportin Paraguay. Mem. Inst. Investig. Cienc. Salud [online]. 2012, vol.10, n.1, pp.85-88. ISSN 1812-9528.

Keratitis caused by Nocardia species is rarely reported in the world and therefore, its impact is not yet well established. The present study reports the first case of keratitis by Nocardia brasiliensis in Paraguay in a male patient, a gardener from Asuncion with a history of trauma with a bush branch two weeks before consultation. The patient came to the Department of Ophthalmology of the Hospital de Clinicas because of a red eye, decreased visual acuity and intense pain in the left eye with a week of evolution. The treatment was performed with the application of reinforced eye drops of gentamicin 14 mg/ml and cefazolin 50 mg/ml, every one hour. Improvement of the symptoms and visual acuity was observed at 10 days of follow-up. The clinical outcome of Nocardia spp keratitis is good as long as the etiologic diagnosis is made promptly and correctly. It is very important to distinguish the borders of the lesions of the corneal ulcer caused by fungi, filamentous bacteria and other bacteria apart from considering the presence of satellite lesions.
