Description
Summary:49-year-old man with diabetic macular edema refractory to antiangiogenics, it is decided to perform therapy with intravitreal dexamethasone implant (Ozurdex; Allergan, California, United States of America). Seven days after treatment, he showed acute endophthalmitis suggestive signs. Despite the intravitreal injection of antibiotics, the patient got worse. Vitreous sampling was repeated for Gram and cultures, and vitrectomy was performed via pars plana. The culture suggested the development of Brevibacterium species. Through an additional test, the presence of Brevibacterium casei was confirmed. Despite the treatment adjusted by antibiogram, retinal ischemia and macular atrophy was evident. Brevibacterium casei is a Gram-positive bacterium, barely pathogenic, that mainly affects immunodepressed patients. Only two cases of endophthalmitis are described, one endogenous and the other one secondary to vegetal trauma. This is the first case of endophthalmitis, secondary to an ophthalmological procedure. Hombre de 49 años, con edema macular diabético refractario a antiangiogénicos, en el que se realizó terapia intravítrea con implante de dexametasona (Ozurdex; Allergan, California, Estados Unidos de América). Tras siete días, presentó signos sugerentes de endoftalmitis aguda. Pese a la inyección intravítrea de antibióticos, el paciente empeoró. Se repitió la toma de muestras en vítreo para Gram y cultivos, y se realizó vitrectomía vía pars plana. El cultivo sugirió el desarrollo de Brevibacterium species. Mediante una prueba adicional, se confirmó la presencia de Brevibacterium casei. Pese al tratamiento ajustado por antibiograma, se evidenció isquemia retiniana y atrofia macular. Brevibacterium casei es una bacteria Gram-positiva, escasamente patógena, que afecta principalmente a inmunodeprimidos. Se han descrito solo dos casos de endoftalmitis, una endógena y otra secundaria a trauma vegetal. Este es el primer caso de endoftalmitis por Brevibacterium casei, secundaria a procedimiento oftalmológico.
