Endoftalmitis de inicio tardío asociada a ampolla de filtración por Moraxella nonliquefaciens / Delayed-onset bleb-related endophthalmitis caused by Moraxella nonliquefaciens

Las endoftalmitis asociadas a la ampolla de filtración tras cirugía filtrante de glaucoma son poco frecuentes, de inicio tardío y la mayoría están asociadas a una blebitis. Los agentes causales suelen ser estreptococos o bacterias gramnegativas. Existen pocos casos descritos en la literatura de endoftalmitis causada por Moraxella nonliquefaciens y la mayoría están asociados a una blebitis tras cirugía filtrante de glaucoma. Presentamos el caso de una paciente de 90 años con endoftalmitis en ojo derecho por Moraxella nonliquefaciens asociada a blebitis 10 años después de la cirugía de glaucoma. Tras el tratamiento, se observó la desaparición de la blebitis 2 semanas después y resolución de la vitritis 29 días después, con recuperación de la visión a valores previos (20/200). La endoftalmitis por Moraxella nonliquefaciens es rara y está asociada a blebitis de inicio tardío tras una cirugía filtrante de glaucoma. A pesar de la virulencia del cuadro, el pronóstico visual suele ser favorable

Bleb-related endophthalmitis is rare and appears months or years after surgery. The causative agents are usually streptococci or gram-negative bacteria. There are few cases in the literature of endophthalmitis caused by Moraxella nonliquefaciens, and most are delayed-onset associated with blebitis after glaucoma filtration surgery. The case is presented of a 90-year-old patient with endophthalmitis in the right eye due to Moraxella nonliquefaciens associated with blebitis 10 years after glaucoma surgery. After treatment, disappearance of blebitis is observed 2 weeks later and resolution of vitritis 29 days later, with recovery of vision to previous values (20/200). Endophthalmitis due to Moraxella nonliquefaciens is rare, and is associated with late onset blebitis after glaucoma filtration surgery. Despite the virulence of the clinical symptoms, the visual prognosis is usually favourable

Queratitis bacteriana por Moraxella nonliquefaciens / Bacterial keratitis due to Moraxella nonliquefaciens

La queratitis bacteriana por Moraxella spp. puede producir importantes complicaciones, siendo la producida por la Moraxella nonliquefaciens(M. nonliquefaciens) la de peor pronóstico. Solo existen tres publicaciones de queratitis por M. nonliquefaciens. Presentamos el caso clínico de un hombre de 79 años, con queratopatía bullosa, recientemente afectado con queratitis infecciosa grave. En la exploración se observa infiltrado estromal denso, profundo y central con hifema. Tras la identificación en cultivo de M. nonliquefaciens y dada la progresión se modifica el tratamiento empírico, según antibiograma, a ciprofloxacino y ceftazidima tópicos, asociando ciprofloxacino y amoxicilina clavulánico orales. Tras 27 días se aprecia resolución total de la lesión con leucoma residual central. La queratitis infecciosa por M. nonliquefaciens es rara y se debe sospechar en pacientes mayores con factores locales predisponentes como daño corneal o cirugía ocular previa. Es importante un tratamiento precoz guiado por antibiograma y un seguimiento cercano para evitar complicaciones y mal cumplimiento

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
