    Abstract:
    Moraxella keratitis can lead to important complications. Moraxella nonliquefaciens(M. nonliquefaciens) has the worst prognosis. Only three cases of corneal infections due to M. nonliquefaciens have been published. The case is presented of a 79-year-old man with bullous keratopathy, recently affected with severe infectious keratitis. Dense, deep, and central stromal infiltrates and hyphaema were detected. After the identification of M. nonliquefaciens in the culture, and given the progression of the condition, the initial empirical treatment was modified to topical ciprofloxacin and ceftazidime in accordance with the antibiogram, combining oral ciprofloxacin and amoxicillin-clavulanate. After 27 days, there was total resolution of the lesion, with central residual leucoma. Keratitis caused by M. nonliquefaciens is rare and must be suspected in elderly patients with local predisposing factors, such as corneal damage or previous eye surgery. Early antibiogram-guided treatment and close monitoring are important to avoid complications and poor compliance.
